RESUMEN

OBJECTIVE: The aim of our study is to explore the relationship between physical performance and visual acuity in university students in China. METHODS: tests of standing long jump, 50-meter dash and pull-ups sit-ups were conducted. The visual acuity was measured using a logarithm of the minimum angle of resolution (logMAR) chart. Pearson correlation was used to test the correlation of physical performance with visual acuity in university students. RESULTS: The number of pull-ups was negatively associated with visual acuity in the left eye for male students, while a negative correlation was found between the time of the 50-meter dash and visual acuity in the right eye for female students. CONCLUSIONS: Our study identified that physical exercise might help improve visual acuity. University students should practice strength exercises to improve physical performance.

RESUMEN

OBJECTIVE: We investigated the associations between objectively assessed sedentary behavior (SB) and moderate-to-vigorous physical activity (MVPA) and body composition variables among a representative sample of Brazilian adults. METHODS: Using an accelerometer, SB and MVPA were monitored for at least 5 days in 524 participants (261 men; age, 18-65 years). Each minute epoch was classified as sedentary or spent in light, moderate, or vigorous physical activity (LPA, MPA, and VPA, respectively). The measured body composition variables included abdominal perimeter (AP) and neck circumference (NC). RESULTS: Men accumulated significantly more min/day of MPA (37.82 versus 27.28), VPA (1.10 versus 0.31), MVPA (39.02 versus 27.61), and steps/day (14,978 versus 13,443) than women (p<.001). In men, MPA, VPA, MVPA, and steps/day were negatively associated with AP (p<.05) independently of SB. Only VPA was significantly associated with NC (ß= 0.113; p=.002). In women, only SB was significantly associated with AP (ß= 0.003; p=.031). There were no significant associations between physical activity intensities and body composition in women. CONCLUSIONS: Our findings on the unequal association of physical activity with body composition variables between sexes can help inform future intervention strategies in Brasil.

RESUMEN

OBJECTIVE: Cardiorespiratory fitness (CRF) is defined as the capacity of the cardiovascular and pulmonary systems to meet the oxygen demands of the body during physical work. Poor CRF is connected with a higher risk for the development of various noninfectious diseases such as cardiovascular disease or malignancies. The standard test for the assessment of CRF is exercise testing with the measurement of maximal oxygen consumption (VO2 max). Standard VO2 max values for adult men and women in the Czech Republic have been available since the 1970s without being updated. According to experts, these standard values are now unusable for contemporary CRF measurements of the population in the Czech Republic. The Fitness Registry and the Importance of Exercise: a National Database (FRIEND) - 4,494 patients (1,717 men) defined new standard values for bicycle ergometry CRF for the population in the United States of America. The aim of the study was the statistical comparison of VO2 max values (reference standards) in the 1970s population in the Czech Republic with the new reference standards of the FRIEND registry. METHODS: All analyses were performed using IBM SPSS statistics and all tests with a p-value of less than 0.05 were considered statistically significant. RESULTS: VO2 max norms for women in the Czech population were higher in all age categories with statistically significant differences in the categories 30-39, 40-49 and 50-59 (p < 0.001). In the male population aged 20-29 years, VO2 max was significantly higher in the FRIEND registry (p < 0.001) in contrast to the other age categories, 30-39, 40-49 and 50-59, which were significantly higher in the Czech population (p < 0.001). CONCLUSIONS: Czech VO2 max population norms from the 1970s are (with the exception of age category 20-29 years) higher than values from the recent FRIEND registry.

RESUMEN

In order to better understand the possible relationships between the application of training loads and the risk of injury in professional women's basketball, four parameters from a professional women's basketball team (N = 11) were analysed: exposure time, number of injuries, rate of perceived exertion (RPE), and workload (sRPE). A total of 3182h of exposure were registered, 2774 were training hours, and 408 were game hours with a total of 9 time loss injuries. The data obtained from each player was related to the exposure time, injury risk, perception of effort, and workload. Several differences were observed between the injury risk values and the morning RPE (F = 5.0811; p = .032), the sRPE of the morning practices (F = 7.3585; p = .010) and the total time of exposure (F = 3.5055; p=.064). There is also a significant negative relationship between total training time and the number of time-loss (TL) injuries (rho = - .797; p = .003), as well as a possible association between exposure time and a lower risk of TL injury (R2 = .645). These findings suggest that an increase in specific exposure time could be associated with a decrease in the risk of time-loss injuries


Con el objetivo de entender mejor las posibles relaciones entre la aplicación de cargas de entrenamiento y el riesgo de lesión en el baloncesto femenino profesional, se analizaron 4 parámetros de un equipo de baloncesto femenino profesional (N = 11): tiempo de exposición, número de lesiones, percepción del esfuerzo después de las sesiones entrenamiento (RPE) y carga de entrenamiento (sRPE). Se registraron 3.182 horas de exposición totales, de las cuales 2.774 fueron de entrenamiento y 408h de competición con un total de 9 lesiones "time-loss" (TL) que comportaron tiempo de actividad perdido. Se relacionan los datos obtenidos de cada jugadora relativos a tiempo de exposición, lesiones, percepción del esfuerzo y carga de trabajo. Se observan posibles diferencias entre los valores de lesionabilidad y RPE de las sesiones de entrenamiento de la mañana (F = 5,0811; p = 0,032), el sRPE de la mañana (F = 7,3585: p = 0,010) y el tiempo total de exposición (F = 3,5055; p = 0,064). Se observa también una relación significativa negativa entre tiempo total de entrenamiento y el número de lesiones TL (rho = -0,797; p = 0,003), así como una posible asociación entre el tiempo de exposición y una menor incidencia lesional TL (R2 = 0,645). Estos valores sugieren que un aumento del tiempo de exposición de carácter específico podría vincularse a la disminución del riesgo de lesiones "time-loss"

RESUMEN

OBJECTIVE: To identify the level of physical activity and glycemic variability of adolescents with type 1 diabetes mellitus and to compare glycemic variability on days with different amounts of moderate to vigorous physical activity (MVPA). SUBJECTS AND METHODS: A sample of 34 subjects aged 10 to 15 years, 18 (52.94%) female; age: 13.04 ± 1.94; HbA1c: 9.76 ± 1.51. Physical activity was measured by wGT3X accelerometer. The glucose data were obtained using continuous glucose monitoring, and the following glycemic variability measures were calculated: standard deviation (SD), low blood glucose index (LBGI), high blood glucose index (HBGI), mean amplitude of glycemic excursions (MAGE), glycemic risk assessment in diabetes equation (GRADE) and coefficient of variation (CV). The most and least active days (the days with greater and lesser time dedicated to physical activities of moderate to vigorous intensity, respectively) were identified. In addition, based on the whole period of accelerometer use, daily means of time spent in MVPA were identified among participants, who were then divided into three groups: up to 100 minutes; from 101 to 200 minutes and above 201 minutes. Then, the measures of glycemic variability were compared among the most and least active days and among the groups too. RESULTS: The amount of MVPA was significantly different between the days evaluated (237.49 ± 93.29 vs. 125.21 ± 58.10 minutes), but glycemic variability measures did not present a significant difference. CONCLUSION: Despite the significant differences in the amount of MVPA between the two days evaluated, the glycemic variability did not change significantly. Arch Endocrinol Metab. 2020;64(3):312-8.

RESUMEN

Pediatric rhabdomyolysis is a common diagnosis that pediatricians need to be able to recognize because prompt treatment can prevent potential complications, such as acute kidney injury. The triggers for rhabdomyolysis are extensive, with viruses being the most common cause in pediatric patients. The pathophysiology behind rhabdomyolysis is complex and still being researched, but having a firm understanding of the cascade that results when muscle injury occurs is essential for proper management. Guidelines for managing pediatric rhabdomyolysis currently do not exist, but this article aims to review the available literature and give clinicians a general approach to aid in history taking, physical examination, diagnosis, acute management, follow-up, and prevention.

RESUMEN

A global pandemic caused by the novel coronavirus (COVID-19) resulted in restrictions to daily living for Canadians, including social distancing and closure of city and provincial recreation facilities, national parks and playgrounds. The objective of this study was to assess how these preemptive measures impacted physical activity behaviour and well-being of Canadians. An online survey was utilized to measure participant physical activity behavior, nature exposure, well-being and anxiety levels. Results indicate that while 40.5% of inactive individuals became less active, only 22.4% of active individuals became less active. Comparatively, 33% of inactive individuals became more active while 40.3% of active individuals became more active. There were significant differences in well-being outcomes in the inactive population between those who were more active, the same or less active (p < 0.001) but this was not seen in the active population. Inactive participants who spent more time engaged in outdoor physical activity had lower anxiety than those who spent less time in outdoor physical activity. Public health measures differentially affected Canadians who were active and inactive and physical activity was strongly associated with well-being outcomes in inactive individuals. This suggests that health promoting measures directed towards inactive individuals may be essential to improving well-being.

RESUMEN

As the benefits of physical activity (PA) in oncology field continue to be demonstrated, multiple structures (sports clubs, associations…) develop PA programs and activities to offer cancer patients survivors the opportunity to continue adapted physical activity. Promoted in the 2014-2019 cancer plan as complementary supportive care, the practice of physical activity is legitimized by the 2016 Health Act of the Ministry of Social Affairs and Health, including the amendment 'prescription health sport', by giving it a legislative framework. In this context of development of new PA offers for cancer patients, it seems necessary to determine and evaluate the structures on their capacities to supervise physical activities for this population with specific needs. This article presents the methodological development and validation process of a tool used to characterize the different structures offering physical activity programs for people who have had cancer, and seeks to define the quality criteria that a structure should meet in the current state of knowledge. Ten of these criteria were selected according to a qualitative methodology and the final tool therefore facilitates the identification of quality programs in post-cancer PA, and could be used systematically by both users and professionals as part of the post-cancer care pathway, as well as by the sport-health platforms themselves in the current dynamics of their deployment throughout the national territory.

RESUMEN

Regular physical activity grants significant health effects and lowers the risk of premature death for all causes, in particular cardiovascular ones in asymptomatic subjects. Physical activity is useful in the primary and secondary prevention of cardiovascular and lung diseases, metabolic diseases, musculoskeletal diseases, cancer and depression. Recent studies correlate inactivity with chronic low-grade inflammation and obesity, at the origin of chronic non-communicable diseases. The evidence must be taken seriously into consideration in this particular CoViD-19 emergency period and long-term effects of prolonged limitation of sports activity must not be overlooked. Contagion in open places is very difficult and the absolute prohibition of sports activities in open places and the closure of parks are creating discomfort and confusion. Institutions and media are generating the wrong message that active people must be looked at with disapproval. Instead, this habit should be encouraged, in order to protect citizens' and community health, lightening the welfare load for society.

RESUMEN

Background: To limit the spread of coronavirus disease 2019 (COVID-19), governments have ordered a series of restrictions that may affect glycemic control in individuals with type 1 diabetes mellitus (T1DM), since physical activity (PA) was not allowed outside home. Methods: We retrospectively evaluated glycemic control of individuals with T1DM using hybrid closed loop (HCL) system in the period before the SARS-CoV-2 outbreak in Italy (February 10-23, 2020-Time 1), when movements were only reduced (February 24-March 8, 2020-Time 2) and during complete lockdown (March 9-22, 2020-Time 3). Information about regular PA (at least 3 h per week) prior and during the quarantine was collected. Results: The study included 13 individuals with a median age of 14.2 years and a good glycemic control at baseline (glucose management indicator of 7%, time in range [TIR] of 68%, time below range [TBR] of 2%). All individuals continued to show good glycemic control throughout the study period. There was an increase in TIR during the study period (+3%) and TIR was significantly higher during Time 3 (72%) than during Time 2 (66%). TBR was significantly lower during Time 3 (1%) both compared with Time 1 and Time 2 (2%). A meaningful variance in TIR at Time 3 between individuals who performed or not PA during quarantine and a significant increase in TIR between Time 2 and Time 3 in individuals both doing PA at baseline and during quarantine was found. At logistic regression, only the presence of PA during quarantine significantly predicted a TIR >70%. Conclusions: Glycemic control of T1DM in adolescents using HCL system did not worsen during the restrictions due to COVID-19 pandemics and further improved in those who continued PA during the quarantine. Maintaining regular PA in a safe home environment is an essential strategy for young individuals with T1DM during the COVID-19 crisis.

RESUMEN

BACKGROUND: To systematically evaluate the effects of physical activity on physiological markers in breast cancer survivors. METHODS: A systematic search of the PubMed, Wed of Science, Medline, CNKI and Wanfang Database was performed to identify eligible randomized controlled trials to explore physical activity on physiological markers in breast cancer survivors. STATA version 13.0 (Stata Corp LP, College Station, TX) was used for all statistical analyses. RESULTS: A total of 11 articles with 941 cases were eligible in this meta-analysis. The results of the meta-analysis showed that physical activity could decrease the levels of insulin (SMD = -1.90, 95%CI: -3.2 to -0.60; I = 92.3%, P < .001), insulin-like growth factor 1 (IGF-I) (WMD = -4.67, 95%CI: -23.14 to 13.79; I = 96.2%, P < .001), insulin-like growth factor binding protein-3 (IGFBP-3) (WMD = -20.09, 95%CI: -47.15 to 6.97; I = 93.3%, P < .001). However, compared with the control group, there was not the significant change of insulin-like growth factor 2 (IGF-II), insulin-like growth factor binding protein-1 (IGFBP-1), leptin, adiponectin, glucose, C-reactive protein (CRP), Interleukin-6 (IL-6), Interleukin-10 (IL-10), and tumor necrosis factor alpha (TNF-ɑ) levels after the intervention. CONCLUSIONS: Physical activity could improve the insulin function that might be associated with decreasing the levels of IGF-I, IGFBP-3 and insulin in breast cancer survivors.

RESUMEN

INTRODUCTION: Physical activity level during pregnancy is unknown in Middle Eastern and North African countries, since no valid tools assessing it exist in Arabic. The aim of this study is to culturally adapt and translate to Arabic an internationally validated instrument, the Pregnancy Physical Activity Questionnaire (PPAQ), and to measure the physical activity of pregnant women using the adapted PPAQ, Arabic version. This tool is time-sparing, self-administered and is the only one taking into account childcare and household chores. METHODS: After following the guidelines for translation and back-translation by certified translators, a committee composed of professionals in the field reviewed each item of the PPAQ, for its comprehensibility. This Arabic version of the PPAQ was tested on a sample of 179 pregnant Lebanese women, from different educational backgrounds, socioeconomic status and gestational ages. RESULTS: Cross-cultural adaptations were applied on the newly translated PPAQ in Arabic version, thus questions referring to some types of outdoor activities were excluded from the final format. Our results reported that 51% and 1.7% of women engage respectively in light and high intensity physical activity, while 18% had a sedentary lifestyle. Occupational type of activities were significantly more performed by women having a higher education (p value 0.001), as opposed to those who attended only high school, who were physically more active in household activities (p value 0.038). Second trimester was a period where pregnant women were active for household, caregiving (p value 0.031), whereas women in their third trimester were physically more active in occupational activities (p value 0.001). Sport-oriented activities were performed by women reporting a good physical status (p value 0.03). Age and crowding index were significantly correlated with occupational, household and caregiving activities (p values 0.004, 0.008 respectively). No significant correlations were observed with pre-gestational body mass index and the physical activity levels. CONCLUSION: A valid tool will help researchers in Arab countries identify physical activity levels of pregnant women and consequently emit specific guidelines relative to the importance and the benefits of a daily active lifestyle throughout gestation.

RESUMEN

La osteoartritis (OA) es una enfermedad crónica, degenerativa, muy invalidante, que destruye en forma gradual y progresiva el cartílago articular en diversas regiones: rodillas, caderas, hombros, manos, tobillos y columna vertebral. En este sentido, el ejercicio ha sido descrito como la intervención no farmacológica más recomendada para pacientes con OA. La práctica regular de ejercicio es considerada un componente integral del estilo de vida saludable; sin embargo, su efecto en el cartílago se mantiene como objeto de debate y especulaciones, así como la relación del ejercicio con el desarrollo de OA. Algunos estudios de modelos animales sugieren que el ejercicio puede ser beneficioso para la salud del cartílago, mientras otros demuestran su efecto nocivo. Una explicación general a estos resultados inconsistentes es que el correr a intensidad moderada tiene efectos beneficiosos, mientras que correr "vigorosamente" o de manera "extenuante" lleva a un efecto nocivo. El objetivo de este trabajo consistió en realizar una revisión de la literatura acerca de los efectos del ejercicio sobre el cartílago artícular, especialmente enfocado a modelos animales experimentales con ratas.


Osteoarthritis (OA) is a chronic, degenerative, and very disabling disease that gradually and progressively destroys articular cartilage in various regions: knees, hips, shoulders, hands, ankles and spine. In this sense, exercise has been described as the most recommended non-pharmacological intervention for patients with OA. Regular exercise is considered an integral component of the healthy lifestyle. However, its effect on cartilage remains the subject of debate and speculation, as well as the relationship between exercise and the development of OA. Some animal model studies suggest that exercise may be beneficial for cartilage health, while others demonstrate its harmful effect. A general explanation for these inconsistent results is that running at moderate intensity has beneficial effects, while running "vigorously" or "strenuously" leads to a harmful effect. The aim of this work was to make a literature review about the effects of exercise on cartilage, especially focused on experimental animal models with rats.

RESUMEN

Burnout is common in physicians who care for patients with serious illness, with rates greater than 60% in some studies. Risk factors for burnout include working on small teams and/or in small organizations, working longer hours and weekends, being younger than 50 years, burdensome documentation requirements, and regulatory issues. Personal factors that can protect against burnout include mindfulness, exercise, healthy sleep patterns, avoiding substance abuse, and having adequate leisure time. Institutional and work factors that can buffer against burnout include working on adequately staffed teams, having a manageable workload, and minimally burdensome electronic health record documentation.

RESUMEN

Marathon runners demonstrate a high incidence of coronary artery plaque; however, studies on runners with exercise-induced hypertension (EIH) are sparse. We aimed to investigate the prevalence of coronary artery plaque among marathon runners with EIH.Veteran male marathon runners (≥40 and <60 years) underwent an exercise stress test. They were divided into 2 groups: normal blood pressure group (NBPG, n = 22), with resting systolic blood pressure (SBP)/diastolic blood pressure <140/90 mm Hg and maximal exercise SBP <210 mm Hg, and EIH group (EIHG, n = 28), with resting blood pressure <140/90 mm Hg and maximal exercise SBP ≥210 mm Hg. Coronary artery plaque and stenosis were compared using multi-detector computed tomography.The proportion of subjects with a coronary artery calcium (CAC) score ≥10 or ≥100 units, 1 or ≥2 plaques, or plaques in ≥2 blood vessels was higher in the EIHG than in the normal blood pressure group (NBPG) (P<.05). The absolute CAC score was higher in the EIHG (42.6 ±â€Š67.8) than in the NBPG (2.8 ±â€Š6.0; P < .05). The CAC score distribution was higher in the EIHG (5-300 units) than in the NBPG (P < .05). The prevalence of coronary plaques and maximal luminal artery stenosis was higher in the EIHG than in the NBPG (P < .05). The EIHG showed 12 cases of stenosis, whereas the NBPG showed only 1 case (P < .05).In marathon runners, EIH was associated with increased prevalence of coronary artery plaques and could be a new risk factor for coronary artery plaque formation. Therefore, preventive measures and EIH monitoring using an exercise stress test, alongside multi-detector computed tomography, are recommended.

RESUMEN

BACKGROUND: Middle-aged and older individuals suffer from skeletal muscle loss due to aging, increasing the risk of sarcopenia. Muscular dystrophy reduces lower-extremity muscle endurance. The annual incidence of falls in the community is about 30-40%. Falls contribute to disability and fractures, affect quality of life, reduce mental health, and, in severe cases, result in death. Therefore, preventing lower limb muscle weakness in middle-aged and older individuals should be taken seriously. PURPOSE: The purpose of this study was to promote community health with a focus on older, community-dwelling individuals. The effects of a lower-extremity exercise intervention on middle-aged and older individuals in terms of improving functional fitness, physiological indexes, exercise self-efficacy, sleep quality, and mental health were explored. METHODS: This study used convenience sampling to recruit community residents over 55 years old as participants, with 50 participants assigned to the control group and to the experimental group, respectively. The experimental group participated in a 50-min lower extremity exercise intervention three times a week for 12 weeks. Differences in functional fitness, basic physiological index, exercise self-efficacy, sleep quality, and mental health variables between the two groups were assessed at the conclusion of the intervention. RESULTS: The lower-extremity muscle exercise program significantly improved functional fitness, physiological indexes, exercise self-efficacy, sleep quality, and overall mental health status in the experimental group, as compared to the control group (p < .05). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: It is recommended that the concept and application of lower extremity movement intervention should be popularized among middle-aged and older individuals to promote physical and mental health, prevent the decline and loss of lower extremity muscle strength, and help realize healthy aging goals.

RESUMEN

Oxidative stress is the core of most pathological situations, and its attribution toward disease conversion is not yet well established. The adaptive capacity of a cell can overcome ROS-induced pathology. However, when a cell fails to extend its maximum adaptive capacity against oxidative stress, it could lead a cell to misbehave or defunct from its normal functions. Any type of physical activity can increase the cells' maximum adaptive capacity, but aging can limit this. However, whether aging is the initiating point of reducing cells' adaptive capacity against oxidative stress or oxidative stress can induce the aging process is a mystery, and it could be the key to solving several uncured diseases. Paradoxically, minimum ROS is needed for cellular homeostasis. Nevertheless, finding factors that can limit or nullify the production of ROS for cellular homeostasis is a million-dollar question. Regular physical exercise is considered to be one of the factors that can limit the production of ROS and increase the ROS-induced benefits in the cells through inducing minimum oxidative stress and increasing maximum adapting capacity against oxidative stress-induced damages. The type and intensity of exercise that can produce such positive effects in the cells remain unclear. Therefore, this review discusses how physical exercise can help to produce minimal positive oxidative stress in preventing skeletal muscle aging.
