RESUMO

BACKGROUND: Objective monitoring of self-directed physical activity (PA) is a common approach used in both fitness and health settings to promote exercise behavior, but adherence has been poor. Newer mobile health (mHealth) technologies could be a cost-effective approach to broadening accessibility and providing support for PA behavior change; yet, the optimal method of delivery of such interventions is still unclear. OBJECTIVE: This study aimed to determine the feasibility and acceptability of an mHealth exercise intervention delivered in combination with objective monitoring in 3 ways: health education emails, asynchronous exercise videos, or synchronous videoconference exercise classes. METHODS: Physically inactive (<30 min/wk) adults (cisgender women aged 31.5, SD 11.3 years, cisgender men aged 34.1, SD 28.9 years, and nonbinary individuals aged 22.0, SD 0 years) were randomized (1:1:1) to 8 weeks of increasing PA behavioral support: level 1 (health education+objective monitoring, n=26), level 2 (asynchronous contact, level 1+prerecorded exercise videos, n=30), or level 3 (synchronous contact, level 1+videoconference group exercise, n=28). Participants used a heart rate monitor during exercise and a mobile app for interaction. Primary outcomes were feasibility (accrual, retention, and adherence) and acceptability (user experience survey). Secondary outcomes assessed at baseline and 8 weeks included resting heart rate, self-reported PA, and quality of life. The exercise dose was evaluated throughout the intervention. RESULTS: Between August 2020 and August 2021, 204 adults were screened for eligibility. Out of 135 eligible participants, 84 (62%) enrolled in the study. Retention was 50% (13/26) in level 1, 60% (18/30) in level 2 and 82% (23/28) in level 3, while adherence was 31% (8/26) in level 1, 40% (12/30) in level 2 and 75% (21/28) in level 3. A total of 83% (70/84) of the study sample completed the intervention, but low response rates (64%, 54/84) were observed postintervention at week-8 assessments. Program satisfaction was highest in participants receiving exercise videos (level 2, 80%, 8/10) or exercise classes (level 3, 80%, 12/15), while only 63% (5/8) of level 1 reported the program as enjoyable. Level 3 was most likely to recommend the program (87%, 13/15), compared to 80% (8/10) in level 2 and 46% (5/8) in level 1. Self-reported PA significantly increased from baseline to intervention in level 3 (P<.001) and level 2 (P=.003), with no change in level 1. Level 3 appeared to exercise at higher doses throughout the intervention. CONCLUSIONS: Only the videoconference exercise class intervention met feasibility criteria, although postintervention response rates were low across all groups. Both videoconference and prerecorded videos had good acceptability, while objective monitoring and health education alone were not feasible or acceptable. Future studies are needed to examine the effectiveness of videoconference exercise interventions on health-related outcomes during nonpandemic times and how asynchronous interventions might maximize adherence.

RESUMO

Purpose: This study aims to investigate the impact of physical activity and self-control on college students' mobile phone addiction through cross-lagged longitudinal surveys, addressing the limitations of previous cross-sectional studies. Patients and methods: A total of 414 college students were tracked three times during a 12-month period using the Physical Activity Rating Scale-3 (PARS-3), the Mobile Phone Addiction Tendency Scale (MPATS), and the Brief Self-Control Scale (BSCS). AMOS25.0 software was used to construct the cross-lagged relationship model, and the maximum likelihood approach was employed to investigate the model fitting. The asynchronous correlation between variables was investigated from the time series through the cross-lagged path coefficient. Results: The fitting indexes of the cross-lagged model showed x 2/df = 5.098, GFI = 0.977, NFI = 0.969, IFI = 0.975, CFI = 0.974; RMSEA = 0.100, and SRMR = 0.030. The calculation conducted by combining the path coefficient of the model shows that PA and SC are the antecedent variables of MPA, and PA is the antecedent variable of SC. In addition, SC serves as a mediator in the path of PA, affecting MPA. Conclusion: (1) physical activity can positively affect subsequent self-control; (2) physical activity can negatively influence subsequent mobile phone addiction; (3) self-control can negatively affect subsequent mobile phone addiction; and (4) physical activity can indirectly influence subsequent mobile phone addiction through self-control.

RESUMO

BACKGROUND AND OBJECTIVES: It has been shown that total knee replacement improves functional capacity and physical activity; however, the influence of age remains unclear. The objective is evaluate the pre and postoperative physical activity measured with the Knee Society Score (KSS) score and the Tegner score. MATERIALS AND METHODS: A retrospective cohort analysis was conducted on patients who underwent total knee replacement (TKR) between January 2016 and December 2019 at our institution. Demographic variables (age, sex, and body mass index), activities of daily living, age-adjusted Charlson Comorbidity Index, American Society of Anesthesiologists score, the Knee Society Score (KSS) in its clinical (KSSc) and functional (KSSf) subscales, the Tegner functional scale, activity variables from the 2011 KSS version, and pain assessment using the visual analog scale were collected. Differences in these variables were analyzed between two age groups: Group A (between 65 and 79 years old) and Group B (80 years or older). RESULTS: A total of 450 patients were evaluated (Group A=245, Group B=167). Group A showed a Tegner improvement of 1.19 (95% CI 1.06/1.31), whereas Group B averaged 0.61 (95% CI 0.43/0.80) (p<0.001). Age >80 was an independent risk factor for less Tegner improvement. In KSSc, Group A improved by 43 points (95% CI 40.82/46.14), while Group B showed a greater increase of 53 points (95% CI 49.74/57.80). Adjusted for confounders, those >80 showed significantly higher KSSc improvement (12.8 points). For KSSf, Group A improved by 33.91 points (95% CI 31.07/36.75), and Group B by 15.57 points (95% CI 11.78/19.35). Adjusted for confounders, patients >80 had less improvement than those <80 (19 points). CONCLUSIONS: Patients who underwent TKR experienced improvements in physical and functional activity parameters. While these improvements were seen in the entire population, they were most notable in patients younger than 80 years.

RESUMO

Despite evidence that aerobic exercise benefits the aging brain, in particular the hippocampus and memory, controlled clinical trials have not comprehensively evaluated effects of aerobic exercise training on human memory in older adults. The central goal of this study was to determine chronic effects of moderate-to-vigorous intensity aerobic exercise on the hippocampus and memory in non-demented, inactive adults ages 55-80 years. We determine effects of aerobic exercise training with a 6-month randomized controlled trial (RCT) comparing 150 min/week of home-based, light intensity exercise with progressive moderate-to-vigorous intensity aerobic exercise. For the first time in a large trial, we examined temporal mechanisms by determining if individual differences in the rapid, immediate effects of moderate intensity exercise on hippocampal-cortical connectivity predict chronic training-related changes over months in connectivity and memory. We examined physiological mechanisms by testing the extent to which chronic training-related changes in cardiorespiratory fitness are a critical factor to memory benefits. The Exercise Effects on Brain Connectivity and Learning from Minutes to Months (Brain-EXTEND) trial is conceptually innovative with advanced measures of hippocampal-dependent learning and memory processes combined with novel capture of the physiological changes, genetic components, and molecular changes induced by aerobic exercise that change hippocampal-cortical connectivity. Given that hippocampal connectivity deteriorates with Alzheimer's and aerobic exercise may contribute to reduced risk of Alzheimer's, our results could lead to an understanding of the physiological mechanisms and moderators by which aerobic exercise reduces risk of this devastating and costly disease.

RESUMO

INTRODUCTION: Friedreich's Ataxia (FRDA) is a multi-system disorder caused by frataxin deficiency. FRDA-related diabetes mellitus (DM) is common. Frataxin supports skeletal muscle mitochondrial oxidative phosphorylation (OXPHOS) capacity, a mediator of insulin sensitivity. Our objective was to test the association between skeletal muscle health and insulin sensitivity and secretion in adults with FRDA without DM. METHODS: Case-control study (NCT02920671). Glucose and insulin metabolism (stable-isotope oral glucose tolerance tests), body composition (dual-energy x-ray absorptiometry), physical activity (self-report), and skeletal muscle OXPHOS capacity (creatine chemical exchange saturation transfer MRI) were assessed. RESULTS: Participants included 11 individuals with FRDA (4 female), median age 27y (IQR 23, 39), BMI 26.9kg/m2 (24.1, 29.4), and 24 controls (11 female), 29y (26, 39), 24.4kg/m2 (21.8, 27.0). Fasting glucose was higher in FRDA (91 vs. 83mg/dL (5.0 vs. 4.6mmol/L), p<0.05). Individuals with FRDA had lower insulin sensitivity (WBISI 2.8 vs. 5.3, p<0.01), higher post-prandial insulin secretion (insulin secretory rate iAUC 30-180 minutes, 24,652 vs. 17,858, p<0.05), and more suppressed post-prandial endogenous glucose production (-0.9% vs. 26.9% of fasting EGP, p<0.05). In regression analyses, lower OXPHOS and inactivity explained some of the difference in insulin sensitivity. More visceral fat contributed to lower insulin sensitivity independent of FRDA. Insulin secretion accounting for sensitivity (disposition index) was not different. CONCLUSIONS: Lower mitochondrial OXPHOS capacity, inactivity, and visceral adiposity contribute to lower insulin sensitivity in FRDA. Higher insulin secretion appears compensatory, and when inadequate, could herald DM. Further studies are needed to determine if muscle- or adipose-focused interventions could delay FRDA-related DM.

RESUMO

OBJECTIVE: Aim: To assess the current state of students' health in higher educational institutions in Ukraine and identify the main measures, factors, and means of its improvement. PATIENTS AND METHODS: Materials and Methods: The research was conducted in 2022-2023 and involved 266 second-year students (82 males, 184 females) from different faculties. Research methods: analysis of literary sources, observation, questionnaire surveys, and statistical methods. RESULTS: Results: A general downward trend in the level of health among students in higher educational institutions in Ukraine has been established. The deterioration of the health of male students is particularly worrying: the number of students with good health has decreased by 34.1 % over the past 10 years, while the number of students with poor and very poor health has increased by 14.0 % and 3.7 %, respectively. It has been found that 41.5 % of male and 34.2 % of female students do not know the cause of their illness and do not know how to prevent it. Students are well aware of the value of their health but do not care about it, are too lazy to exercise and rely on medications or a doctor when they are ill. CONCLUSION: Conclusions: A student's health is his or her social and personal values, level of culture, ability to withstand heavy physical and mental stress, and ability to adapt to various external factors. Therefore, the primary task of physical education departments should be to form the interests, desires, and motives of students for physical exercise.

RESUMO

There is evidence that neighbourhood walkability and greenery are associated with walking, but less is known about their joint associations. We investigated this using data from the AusDiab3 study (2011/12) with 3032 adults (mean age 60 years). Two-level logistic regression models were used with binary walking outcomes. There was an inverse relationship (r = -0.5) between walkability (a composite measure of residential, destinations and intersections densities) and greenery (the size of densely vegetated areas). However, both walkability and greenery were independently positively associated with odds of walking. Regarding joint associations, in low-walkability neighbourhoods, greenery was positively associated with walking. In high-walkability neighbourhoods, greenery was not associated with walking.

RESUMO

Las actividades que realiza el profesional de la enfermería les producen quebranto en la salud, siendo el estrés el primer factor que va a afectar el ritmo propio, ocasionando irritabilidad y ansiedad. La práctica físico-deportiva tiene un efecto positivo sobre su salud física y mental debido a que produce liberación de endorfinas, lo que conlleva una reducción de la ansiedad, la depresión y el estrés, ya que cualquier tipo de actividad física, ya sea de bajo o alto impacto, libera estas sustancias que actúan directamente sobre el cerebro, produciendo sensación de bienestar y relajación inmediata. Se presenta una investigación con un diseño no experimental, desde el enfoque cuantitativo de tipo descriptivo comparativo de corte transversal. Tiene como objetivo: determinar las relaciones entre actividad física y regulación emocional de un grupo de enfermeras (o) s del Hospital Sur en Chilpancingo, Guerrero, México. Se aplicó la Escala para Evaluación de la Inteligencia Emocional TMMS-24 y el Cuestionario Internacional de Actividad Física (IPAQ). Para determinar la relación entre las variables se empleó la Correlación del Rho de Spearman. Las dimensiones estudiadas son la atención, claridad y reparación emocional por parte de la variable dependiente (Control emocional) y las dimensiones Alta, Media y Baja por la variable independiente (Actividad física). En la comunidad donde se observaron los signos y síntomas de nerviosismo, agitación o tensión asociados a situaciones de ansiedad y estrés, se establecen correlaciones directas entre la intensidad de la actividad física y el control emocional de los sujetos investigados, o sea, a menor intensidad de la actividad física menor control y regulación emocional.


As atividades realizadas pelo profissional de enfermagem causam-lhe problemas de saúde, sendo o estresse o primeiro fator que afetará seu próprio ritmo, causando irritabilidade e ansiedade. A prática físico-esportiva tem um efeito positivo sobre sua saúde física e mental, pois produz uma liberação de endorfinas, o que leva a uma redução da ansiedade, da depressão e do estresse, pois qualquer tipo de atividade física, seja ela de baixo ou alto impacto, libera essas substâncias que atuam diretamente no cérebro, produzindo uma sensação de bem-estar e relaxamento imediato. A pesquisa é apresentada em um desenho não-experimental, a partir de uma abordagem quantitativa, descritiva, comparativa, transversal e de corte transversal. Seu objetivo é determinar a relação entre a atividade física e a regulação emocional em um grupo de enfermeiras do Hospital Sur em Chilpancingo, Guerrero, México. Foram aplicados o Emotional Intelligence Rating Scale TMMS-24 e o International Physical Activity Questionnaire (IPAQ). A Correlação Rho de Spearman foi usada para determinar a relação entre as variáveis. As dimensões estudadas são Atenção, Clareza e Reparação Emocional para a variável dependente (Controle Emocional) e as dimensões Alta, Média e Baixa para a variável independente (Atividade Física). Na comunidade onde foram observados os sinais e sintomas de nervosismo, agitação ou tensão associados a situações de ansiedade e estresse, foram estabelecidas correlações diretas entre a intensidade da atividade física e o controle emocional dos sujeitos investigados, ou seja, quanto menor a intensidade da atividade física, menor o controle e a regulação emocional.


The activities carried out by the nursing professional produce them health problems, with stress being the first factor that will affect one's own rhythm, causing irritability and anxiety. Physical-sports practice has a positive effect on their physical and mental health because it produces the release of endorphins, which leads to a reduction in anxiety, depression and stress because any type of physical activity, whether low or high impact, releases these substances that act directly on the brain, producing a feeling of well-being and immediate relaxation. A research is presented with a non-experimental design, from the quantitative approach of a cross-sectional comparative descriptive type. Its objective is to determine the relationships between physical activity and emotional regulation of a group of nurses from the Sur Hospital in Chilpancingo, Guerrero, Mexico. The TMMS-24 Emotional Intelligence Assessment Scale and the International Physical Activity Questionnaire (IPAQ) were applied. To determine the relationship between the variables, Spearman's Rho Correlation was used. The dimensions studied are attention, clarity and emotional repair by the dependent variable (Emotional Control) and the High, Medium and Low dimensions by the independent variable (Physical Activity). In the community where the signs and symptoms of nervousness, agitation or tension associated with situations of anxiety and stress were observed, direct correlations were established between the intensity of physical activity and the emotional control of the subjects studied, that is, at a lower intensity of physical activity, less control and emotional regulation.

RESUMO

Se reconoce que la danza afroecuatoriana es un lazo de conexión con los ancestros y la identidad, y aporta una educación del movimiento que facilita, a su vez, el desarrollo de valores educativos en torno al tratamiento del cuerpo; ello favorece la motivación hacia la práctica de la actividad física continuada. El objetivo de la investigación radica en proponer la danza afroecuatoriana como una alternativa metodológica para la inclusión de estudiantes con hiperactividad y se contextualiza en décimo año, con un total de 35 estudiantes, y una muestra de un estudiante con trastorno por déficit de atención e hiperactividad, de la Básica Superior de la Unidad Educativa "José Otilio Ramírez Reina", provincia de Esmeraldas en Ecuador. El estudio, se sustentó en un enfoque cuantitativo-cualitativo y el método dialectico-materialista; se emplearon métodos del nivel teórico como el histórico-lógico y el análisis-síntesis y del nivel empírico el análisis documental, la observación y la encuesta, para interpretar las derivaciones obtenidas en cada etapa que transitó desde el nivel exploratorio, descriptivo, hasta llegar a una explicación del fenómeno investigado. Los resultados revelan el insuficiente reconocimiento de la danza afroecuatoriana para la inclusión de estudiantes con este trastorno, así como la escasa producción científica relacionada con la temática. Del estudio realizado se concluyó que la danza afroecuatoriana constituye una vía expedita para un mejor conocimiento, disfrute y preservación de la identidad, en estos estudiantes.


Reconhece-se que a dança afro-equatoriana é um vínculo de ligação com os ancestrais e a identidade, e proporciona uma educação em movimento que facilita, por sua vez, o desenvolvimento de valores educativos em torno do tratamento do corpo; Isso favorece a motivação para a prática de atividade física continuada. O objetivo da pesquisa consiste em propor a dança afro-equatoriana como alternativa metodológica para a inclusão de alunos com hiperatividade e está contextualizada no décimo ano, com um total de 35 alunos, e uma amostra de um aluno com transtorno de déficit de atenção e hiperatividade, da Escola Básica Superior da Unidade Educacional "José Otilio Ramírez Reina", província de Esmeraldas no Equador. O estudo baseou-se na abordagem quanti-qualitativa e no método dialético-materialista; Métodos do nível teórico como histórico-lógico e análise-síntese e do nível empírico, análise documental, observação e levantamento, foram utilizados para interpretar as derivações obtidas em cada etapa que passou do nível exploratório, descritivo, até chegar a uma explicação do fenômeno investigado. Os resultados revelam o insuficiente reconhecimento da dança afro-equatoriana para a inclusão de alunos com esse transtorno, bem como a limitada produção científica relacionada ao tema. Do estudo realizado concluiu-se que a dança afro-equatoriana constitui um caminho expedito para um melhor conhecimento, diversão e preservação da identidade destes alunos.


Afro-Ecuadorian dance is a bond of connection with ancestors and identity, and provides an education in movement that facilitates, in turn, the development of educational values around the treatment of the body; this favors motivation towards the practice of continued physical activity. The objective of the research lies in proposing Afro-Ecuadorian dance as a methodological alternative for the inclusion of students with hyperactivity and is contextualized in the tenth grade, with a total of 35 students, and a sample of a student with attention deficit hyperactivity disorder, from the Higher Basic School "José Otilio Ramírez Reina" Educational Unit, province of Esmeraldas in Ecuador. The study was based on a quantitative-qualitative approach and the dialectical-materialist method; methods from the theoretical level such as historical-logical and analysis-synthesis and from the empirical level, documentary analysis, observation and survey, were used to interpret the derivations obtained in each stage that went from the exploratory, descriptive level, until reaching an explanation of the phenomenon investigated. The results reveal the insufficient recognition of Afro-Ecuadorian dance for the inclusion of students with this disorder, as well as the limited scientific production related to the topic. From the study carried out, it was concluded that Afro-Ecuadorian dance constitutes an expeditious route for better knowledge, enjoyment and preservation of identity in these students.

RESUMO

BACKGROUND: The WHO issued recommendations about the ideal amount of physical activity, sedentary behaviour and sleep in infants, toddlers and preschool children. To facilitate their interpretation and translation into public health policies, we analysed the quantity and quality of the evidence that supported the development of each WHO recommendation. METHODS: All data for each exposure-outcome pair analysed in the studies informing WHO guidelines were extracted, and predefined criteria, based upon GRADE methodology, were used to classify each outcome and study result. RESULTS: Among the 237 studies that could be included, 37 were experimental and 200 were observational, yielding 920 analyses of exposure-outcome associations. Sixty-two analyses used a relevant outcome, with or without significant results. Five of the 10 WHO recommendations were based upon zero analyses with significant results on relevant health outcomes. The remaining recommendations were mostly based upon analyses evaluating obesity-related outcomes. Eight of the 10 GLs thresholds were not supported by any significant analysis on clinically relevant outcomes. CONCLUSION: While these findings should not be interpreted as an attempt to disprove the benefits of healthy lifestyle habits in early childhood, neither to minimize the work of the experts in this complex research field, very limited evidence currently supports the adoption of recommended thresholds as behavioural surveillance and public health interventions targets. Therefore, until further data are available, public health interventions should be developed balancing whether to focus on the achievement of specific targets that are still not supported by high-quality evidence or on the general promotion of healthy behaviours.

RESUMO

BACKGROUND: Several studies have examined the impact of leadership on employee well-being and health. However, this research has focused on a variable-centred approach. By contrast, the present study adopts a person-centred approach. AIMS: To (a) identify latent 'resources' profiles among two samples combining vigour at work, work engagement and physical activity levels; (b) examine the link between the identified profiles and indicators of psychological/physical health; and (c) test whether different levels of transformational leadership determine the probability of belonging to a particular profile. METHOD: Two samples of workers, S1 and S2 (NS1 = 354; NS2 = 158), completed a cross-sectional survey before their annual medical examination. RESULTS: For S1, the results of latent profile analysis yielded three profiles: spiritless, spirited and high-spirited. Both high-spirited and spirited profiles showed a positive relationship with mental health, whereas spiritless showed a negative relationship. For S2, two profiles (spirited and spiritless) were replicated, with similar effects on mental health, but none of them was related to total cholesterol. In both samples, transformational leadership determined the probability of belonging to a particular profile. CONCLUSIONS: Transformational leadership increased the probability of belonging to a more positive profile and, therefore, to better workers' health.

RESUMO

AIMS: Physical activity (PA) and nutrition are important determinants of health in late adulthood. However, low levels of PA and poor nutrition are common in older adults and have become more prevalent during the COVID-19 pandemic. We hypothesised that Healthy Conversation Skills could be used to support health behaviour changes beneficial for health in older adults and thus conducted a study nested within the UK Hertfordshire Cohort Study. METHODS: Between November 2019 and March 2020, 176 participants were visited at home. A trained researcher administered a questionnaire and undertook anthropometric and physical performance tests. A total of 89 participants were randomised to the control group and received a healthy living leaflet; 87 participants in the intervention group were interviewed using Healthy Conversation Skills at the initial visit with follow-up telephone calls at 1, 3, 6 and 9 months. Follow-up at 1 year by postal questionnaire assessed change in PA and diet. In total, 155 participants (79 control and 76 intervention) completed the baseline and 1-year follow-up. RESULTS: At baseline, median (lower quartile, upper quartile) age (years) was 83.1 (81.5, 85.5) and median PA time (min/day) from walking, cycling and sports was 30.0 (15.0, 60.0). In total, 95% of participants completed the intervention; the total response rate for postal questionnaires was 94%. There were no statistically significant differences in outcomes between the trial arms. In women, there was a tendency for greater increases in diet quality in the intervention group compared to the control group (p = 0.075), while among men, there was a tendency for reduced decline in self-reported physical function in the intervention group compared to the control group (p = 0.081). CONCLUSION: We have shown that it is viable to utilise Healthy Conversation Skills via telephone to promote healthier lifestyles in older adults. Larger appropriately powered studies to determine the efficacy of such an intervention are now warranted.

RESUMO

AIMS: To investigate the association of accelerometer-measured intensity-specific physical activity (PA) with all-cause and cause-specific mortality among individuals with cardiovascular disease (CVD). METHODS: In this prospective cohort study, 8,024 individuals with pre-existing CVD (mean age: 66.6 years, female: 34.1%) from the UK Biobank had their PA measured using wrist-worn accelerometers over a 7-day period in 2013-2015. All-cause, cancer, and CVD mortality was ascertained from death registries. Cox regression modelling and restricted cubic splines were used to assess the associations. Population-attributable fractions (PAFs) were used to estimate the proportion of preventable deaths if more PA were undertaken. RESULTS: During an average of 6.8 years of follow-up, 691 deaths (273 from cancer and 219 from CVD) were recorded. An inverse non-linear association was found between PA duration and all-cause mortality risk, irrespective of PA intensity. The hazard ratio (HR) of all-cause mortality plateaued at 1800 minutes/week for light-intensity PA (LPA), 320 minutes/week for moderate-intensity PA (MPA) and 15 minutes/week for vigorous-intensity PA (VPA). The highest quartile of PA associated lower risks for all-cause mortality, with HRs of 0.63 (95% confidence interval [CI]: 0.51-0.79), 0.42 (0.33-0.54) and 0.47 (0.37-0.60) for LPA, MPA, and VPA, respectively. Similar associations were observed for cancer and CVD mortality. Additionally, the highest PAF were noted for VPA, followed by MPA. CONCLUSION: We found an inverse non-linear association between all intensities of PA (LPA, MPA, VPA, and MVPA) and mortality risk in CVD patients using accelerometer-derived data, but with larger magnitude of the associations than that in previous studies based on self-reported PA.


This study investigated the associations of accelerometer-derived intensity-specific physical activity (PA) with the risks of all-cause and cause-specific mortality among individuals with cardiovascular disease (CVD). L-shaped dose-response relationships between the duration of PA and all-cause mortality were observed across all levels of PA intensities. The risk reduction for mortality exhibited a sharp decline from 0 to 1800 minutes/week of light-intensity PA, followed by reaching a plateau. Notably, the inflection points for moderate-intensity PA and vigorous-intensity PA were found at 320 and 15 minutes per week, respectively. The population-attributable fraction analysis indicated that a significant number of deaths could potentially be prevented if individuals with CVD engaged in more vigorous physical activities.

RESUMO

In this editorial, we comment on the article by Stafie et al. Inflammatory bowel disease (IBD) constitutes a cluster of chronic and progressive inflammatory disorders affecting the digestive system. IBD can impede an individual's capacity to perform daily activities, hinder work productivity, limit physical capabilities, and negatively impact medical outcomes. Although physical activity and structured exercise programs are becoming increasingly important in many chronic inflammatory diseases, they are not being sufficiently implemented in IBD patients. Effective prevention of future disability and drug dependence in IBD patients requires timely diagnosis and treatment of musculoskeletal problems, including sarcopenia, as well as decreased muscle strength, aerobic capacity, and bone mineral density. To improve treatment outcomes for IBD patients, it is crucial to develop individualized rehabilitation programs tailored to their unique needs. Equally critical is the active participation of pertinent departments in this process. It is imperative to highlight the significance of creating a personalized rehabilitation program with a multidisciplinary approach in IBD management.

RESUMO

Introduction: The purpose of the present study was to investigate the impact of the FIT FIRST FOR ALL school-based physical activity program on health-related physical fitness in Faroese schoolchildren. The program aimed to add three weekly sessions of organized high-intensity physical activity to the standard weekly physical education sessions for all pupils across the entire school. Methods: A non-randomized controlled design was used to evaluate the effects of the program. Two schools participated, including one intervention school (INT; n =179) and one control school (CON; n =181), with pupils aged 7-16 years (grades 1-9). The FIT FIRST FOR ALL program consisted of three weekly 40-minute sessions of age-adjusted high-intensity physical activity over 10 weeks for the INT school, while the CON school continued their normal school program. Pre- and post-intervention assessments included cardiorespiratory fitness (Yo-Yo IR1C test), agility (Arrowhead Agility test), postural balance (Stork Stand), standing long jump performance, body composition, blood pressure, and resting heart rate. Results: A significant time × group effect (p < 0.001) was observed for cardiorespiratory fitness, which increased by 31% [23;39] in INT (p < 0.001) and remained unaltered in CON (7% [-2;16], p = 0.13). In addition, a time × group effect (p < 0.001) was observed for agility, which improved by 2.1% [1.0;3.2] in INT (p < 0.001) and regressed by 3.3% [2.3;4.4] in CON (p < 0.001). No significant between-group effects were found for standing long jump and balance. A time × group effect (p < 0.001) was observed for changes in total muscle mass, which increased by 1.4 kg [1.2;1.5] in INT (p < 0.001) and by 0.4 kg [0.3;0.6] in CON (p < 0.05). Furthermore, a time × group effect (p < 0.001) was observed for total fat percentage, which decreased by -2.3% [-2.8;-1.9] in INT (p < 0.001) and remained unchanged in CON (-0.3% [-0.7;0.1], p = 0.16). No significant time × group effects were found for blood pressure and resting heart rate. Discussion: The FIT FIRST FOR ALL program significantly improved cardiorespiratory fitness and agility, and it led to favorable changes in body composition in the intervention school. These findings suggest that the program is highly effective in enhancing physical fitness and health status across all investigated age groups when implemented at a school-wide level.

RESUMO

In Swedish school health services, local initiatives have been taken to use physical activity on prescription (PAP) to encourage physically inactive children to become more active. Previous research shows that interprofessional collaboration plays a crucial role in promoting physical activity in children, as well as in promoting health in schools. However, there is a lack of knowledge about PAP for children in the school setting, including how medical and educational staff can work together to encourage children who have been recommended PAP. Therefore, this study aims to explore the perceived facilitators and barriers concerning interprofessional collaboration regarding physical activity on prescription in the school setting, as viewed from the professionals' perspectives. Semi-structured interviews were conducted with 21 professionals who work with the method in school settings. The data were analyzed using Reflexive Thematic Analysis. The results reveal both barriers and facilitators for interprofessional collaboration on PAP in the school setting, as perceived by professionals. Organizational and structural obstacles within school institutions hinder collaboration, while a shared commitment to PAP, characterized by consensus-building, acts as a facilitating factor. PAP for children in a school setting is still an unexplored area and further research is required.

RESUMO

It is widely assumed crime and related concerns, including neighborhood incivilities and fear of crime, are barriers to physical activity (PA). Past studies reveal mixed evidence. Studies of impacts for crime-protective factors are less common but have similarly mixed results. This paper evaluates a comprehensive transdisciplinary conceptual framework of cross-sectional associations between crime-related perceptions and reported minutes/week of recreational walking inside and outside one's home neighborhood. Safe and Fit Environments Study (SAFE) recruited and surveyed 2302 participants from adolescents to older adults from four U.S. metropolitan areas. A zero-inflated model estimated two components of each outcome: whether the respondent walked, and minutes/week walked. Correlates of recreational walking were location-specific, differing based on walking location. Fear of crime, risk evaluation, victimization, and incivilities were not consistently associated with walking for recreation inside one's neighborhood. People with crime concerns about their own neighborhoods, however, more commonly walked for recreation outside their neighborhoods. Protective crime-related perceptions that seldom have been studied in relation to PA, such as street efficacy (i.e., the perceived ability to avoid and manage danger), were strongly associated with recreational walking in both locations, indicating the additional heuristic value of the SAFE conceptual framework. Crime-related perceptions and walking for recreation: Evaluating a conceptual model.

RESUMO

INTRODUCTION: Cardiovascular disease (CVD) remains a leading cause of mortality and morbidity globally, particularly among older adults. In India, the rapid demographic transition has resulted in a significant increase in the aging population, necessitating a deeper understanding of the factors influencing CVD prevalence. This study examines the association between physical activity and the prevalence of CVD among individuals aged 60 and above. DATA & METHODS: The study utilized cross-sectional data from the LASI, comprising a nationally representative sample of 28,935 individuals. Logistic regression analysis was employed to investigate the relationship between physical activity and CVD. Population Attributable Factor (PAF) was calculated to determine the proportion of CVD cases preventable by recommended physical activity levels. RESULTS: Adequate physical activity was significantly associated with lower odds of CVD (OR 0.72, 95% CI 0.67-0.78). Inadequate physical activity also showed a protective effect (OR 0.88, 95% CI 0.83-0.94) compared to those who never worked. Other significant factors influencing CVD risk included age, sex, educational level, living arrangements, self-rated health status, body mass index, smoking habits, and multi-morbidity. The comparison between adequate physical activity levels and never physically active shows a PAF estimate of 0.093 (95% CI: 0.071 - 0.114), indicating that 9.3% of cardiovascular disease cases could be prevented by increasing physical activity from never active to adequate levels. CONCLUSION: The findings highlight the significant role of physical activity in reducing CVD risk among older adults in India. Promoting regular physical activity through community-based programs and healthcare interventions could substantially lower the burden of CVD.

RESUMO

INTRODUCTION: Physical inactivity and sedentary behavior are recognized as independent risk factors for many diseases. However, studies investigating their associations with total and cause-specific mortality in low-income and Black populations are limited, particularly among older adults. METHODS: A prospective cohort study was conducted among 8,337 predominantly low-income and Black Americans aged ≥65 years residing in the southern United States. Participants reported their daily sitting time and leisure-time physical activity (LTPA) at baseline (2002-2009), and mortality data were collected through 2019. Analysis was conducted from September 2022 to October 2023. RESULTS: During a median follow-up of 12.25 years, nearly 50% (n = 4,111) were deceased. A prolonged sitting time (>10 hours/day vs. <4 hours/day) was associated with an elevated all-cause mortality (HR, 1.15; 95% CI, 1.04-1.27) after adjusting for LTPA and other potential confounders. LTPA was associated with a reduced risk of all-cause mortality, with an adjusted HR of 0.75 (95% CI 0.64, 0.88) associated with 150 to 300 minutes per week of moderate-intensity physical activity. Individuals who were physically inactive and had a sitting time of >10 h/d had the highest mortality risk (HR, 1.48; 95% CI, 1.23-1.78), compared with those who were physically active and had low sitting time. These associations were more pronounced for mortality due to cardiovascular diseases (CVD). CONCLUSIONS: High sitting time is an independent risk factor for all-cause and CVD mortality, and LTPA could partially attenuate the adverse association of prolonged sitting time with mortality.

RESUMO

On a global scale, 15% of couples experience infertility. Approximately 50% of these cases refer to male infertility. This literature review investigated the effects of exercise activities on male fertility and reproductive health. This subject was explored using studies conducted on human and animal models. Physical activity is widely recognized to improve overall well-being, but engaging in excessive exercise might potentially lead to male infertility due to the negative impact on hypothalamic-pituitary-testicular (HPT) function, increased oxidative stress, and the presence of chronic inflammation. Infertility might result from the fundamental factors that induce a decline in testosterone production and semen quality. Physical activity has the potential strategy to enhance male fertility in cases of infertility caused by obesity and diabetes. Exercise enhances spermatogenesis and semen quality in lifestyle-induced infertility by increasing testicular antioxidant defense, reducing pro-inflammatory cytokines, and promoting steroidogenesis.
