The Athlete Psychological Well-Being Inventory: Factor Equivalence with the Sport Injury-Related Growth Inventory.

Until now, research on growth following sport injury has relied exclusively on retrospective reports and nomothetic measures drawn from other fields of research. Therefore, to more objectively explore growth following sport injury pre- and post-injury, rather than retrospectively, this study adapts and examines the psychometric properties of the Athlete Psychological Well-Being Inventory (APWBI), which can be used throughout the sport injury process (i.e., prior to and following sport injury). A sample of 164 athletes free from injury (71.3% men; M age = 19.7 years, SD = 2.1) were compared to a sample of 168 athletes with history of previous injury (73.2% men; M age = 19.7 years, SD = 2.1). Multigroup Confirmatory Factor Analysis demonstrated the measurement and factor equivalence between the APWBI and a retrospective measure, the Sport Injury-Related Growth Inventory (SIRGI). The APWBI also showed satisfactory to excellent internal consistency reliability for all its sub-dimensions ("sense of mastery", "positive relations with others", "responsibility for one's health", "self-awareness", "emotional ability", "purpose in life", "purpose in sport", and "body awareness") and for the total score. Analysis of the relationships with other self-report measures (i.e., the Positive Functioning Inventory, the Rosenberg's Self-Esteem Scale, and the Lie Scale) provided convergent and discriminant evidence to support the construct validity of the instrument. To conclude, the APWBI is a valid and reliable instrument for use within English-speaking athletes of various competitive levels (from local/county to international level).

Left Ventricular Hypertrophy in Male and Female Judo Athletes.

Changes in cardiac geometry develop after intense and prolonged training. Left ventricular enlargement, increased relative wall thickness, and growing mass of the left ventricle occur after strenuous exercise. Combat sports such as judo can lead to left ventricular hypertrophy. Previous studies have found that there are differences in left ventricular chamber size and thickness between the sexes, with female athletes having smaller wall diameters and less hypertrophy than male athletes. The research aims to examine heart muscle adaptations and remodeling of cardiac geometry among elite judo athletes and to evaluate differences between males and females. A cross-sectional study included a group of 19 (males n=10, females n=9) professional judokas between 20 and 30 years. Demographic and anthropometric data were collected. Cardiac geometry was determined by two-dimensional transthoracic echocardiography. In terms of left ventricular mass and the left ventricular mass index significant differences were found between male and female judokas (233.44±68.75 g vs. 164.11±16.59 g, p=0.009), (105.16±24.89 vs. 84.66±15.06, p=0.044), respectively. A greater enlargement of the heart muscle is observed in male athletes compared to the female group. Left ventricle enlargement is likely to occur among elite-level judokas.

Objectively evaluated physical activity among individuals following anterior cruciate ligament reconstruction: a systematic review and meta-analysis.

Objective: To compare time spent in moderate-to-vigorous physical activity (MVPA) per week, MVPA per day, and steps per day between individuals that were subjected to the anterior cruciate ligament reconstruction (ACLR) and healthy control group. Design: Systematic review and meta-analysis of observational studies. Data sources: Web of Science, Scopus, and PubMed have been comprehensively searched to identify relevant investigations. Eligibility criteria for selecting studies: An observational research that objectively evaluated physical activity among respondents with a history of ACLR. Results: Of 302 records, a total of 12 studies fulfilled the eligibility criteria. Four hundred and forty-three participants underwent the ACLR, 153 men and 290 women. The mean time between anterior cruciate ligament (ACL) surgery and evaluation of analysed outcomes was 34.8 months. The main findings demonstrated that the ACLR group spent less time in weekly MVPA (standardised mean differences (SMD)=-0.43 (95% CI -0.66 to -0.20); mean = -55.86 min (95% CI -86.45 to -25.27); p=0.0003; τ2=0.00), in daily MVPA (SMD=-0.51 95% CI -0.76 to -0.26]; mean = -15.59 min (95% CI -22.93 to -8.25); p<0.0001; τ2=0.00), and they had fewer daily steps (SMD=-0.60 95% CI -0.90 to -0.30); mean = -1724.39 steps (95% CI -2552.27 to -896.50); p<0.0001; τ2=0.00) relative to their non-injured counterparts. Additionally, available investigations indicated that individuals with a history of ACLR participated in 316.8 min of MVPA per week, 67 min in MVPA per day, and 8337 steps per day. Conclusion: Long-term after ACLR, participants undergoing ACL surgery were less physically active compared with their non-injured peers, and they did not satisfy recommendations regarding steps per day. PROSPERO registration number: CRD42023431991.

Prevalence of metabolic syndrome and its association with rapid weight loss among former elite combat sports athletes in Serbia.

BACKGROUND: In terms of the potential influence of rapid weight loss (RWL) on the metabolic health of former combat sports athletes (CSA), the scientific literature is quite scarce. Therefore, the objective of the presented research was to determine the differences in metabolic syndrome (MetS) parameters and the prevalence of MetS between former athletes who performed RWL and athletes who did not. METHODS: The sample of the presented study comprised 150 participants from Serbia, equally divided into two groups: 75 former athletes who had practiced combat sports and 75 ex-athletes of various other sports who did not practice RWL during their careers. The following parameters related to the MetS were evaluated: waist circumference, high-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure, fasting glucose, and triglycerides. The oral glucose tolerance test (OGTT) was used to assess the participant's body response to sugar. RESULTS: The RWL group had significantly higher both systolic (p < 0.001) and diastolic blood pressure (p < 0.001) compared to the group of athletes who did not practice weight reduction during their careers. Additionally, a tendency toward statistically significant differences between groups was recorded in the variable triglycerides (p = 0.069). Regarding OGTT, increased values of fasting blood glucose at the final measurement were revealed only in the RWL group (p = 0.003). The prevalence of MetS was substantially higher in CSA than in the control group (39.5% vs. 16.2%, respectively p = 0.002). CONCLUSIONS: This study suggests that former elite CSA who used RWL during their sports career are susceptible to negative metabolic alterations at the end of their competitive period.

The influence of body mass index on physical activity engagement following anterior cruciate ligament reconstruction: A systematic literature review.

Background: The objective of this study was to summarize available literature that explored the impact of body mass index (BMI) on physical activity participation among individuals who were subjected to the anterior cruciate ligament reconstruction (ACLR). Methods: A total of three electronic databases, including Web of Science, Scopus, and PubMed, were comprehensively searched to identify relevant investigations. The following inclusion criteria were applied: (1) study design was observational; (2) participants underwent the ACLR; (3) BMI was estimated as a predictor variable; and (4) outcomes evaluated referred to physical activity. The risk of bias was assessed with the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Results: After a database search, 787 studies were found, and only 10 of them met each of the eligibility criteria and were included in the qualitative analysis. Regarding respondents' characteristics, 7171 individuals underwent ACLR, 4080 males and 3091 females, with a mean age of 25.5 years. Most importantly, the average BMI of the examined population was 24.9 kg/m2. In all studies, physical activity was evaluated subjectively using the Tegner activity scale and the Marx activity scale. The main findings unambiguously demonstrated that a negative relationship between BMI and physical activity engagement was observed. More specifically, there is convincing evidence that BMI over 25 kg/m2 harmfully affected subjectively assessed physical activity in individuals with a history of ACLR. Conclusion: The results obtained in the presented research indicated that increased values of BMI were a factor that correlated with reduced physical activity levels in the ACLR population. Hence, taking into account the clinical and health implications of reduced physical activity participation, stimulation of a healthy lifestyle, such as a combination of adequately designed physical exercise and nutrition, seems necessary for the analyzed population.

Rapid weight loss can increase the risk of acute kidney injury in wrestlers.

Objective: Restrictive diets, forced starvation or voluntary weight loss are attracting more and more attention from scientists. Overall trends show that about 80% of combat sports athletes use specific methods of reducing body mass. Rapid weight loss could be a risk factor for kidney-related adverse outcomes. This study aimed to examine the impact of high-intensity specific training combined with rapid weight loss in the first and without rapid weight loss in the second phases on body composition and biochemical markers of kidney function. Methods: The study was conducted on 12 male wrestlers. Kidney function markers were measured, including blood urea nitrogen, serum creatinine, uric acid and serum Cystatin-C. Alterations in analysed markers were noted in both phases of the research. Results: According to the data, a significant increase was noted in blood urea nitrogen (p=0.002), uric acid (p=0.000) and serum creatinine (p=0.006) during the first phase in comparison with the second phase. The levels of serum Cystatin-C were slightly elevated after both phases compared with the initial measurement. Conclusion: It is evident that high-intensity specific training combined with rapid weight loss significantly affects the increase in kidney function markers compared with identical training without rapid weight loss. The findings in this study suggest that rapid body mass reduction is associated with an increased risk of acute kidney injury in wrestlers.

Psychometric Properties of the Italian Version of the Emiq-Hp (Exercise in Mental Illness Questionnaire-Health Professionals Version) to Investigate the Views of Health Professionals Regarding Exercise for Treatment of Mental Illness.

Objective: People with mental illness experience a significantly increased mortality rate, partly attributable to high rates of premature metabolic disease. Exercise is increasingly recognized as an evidence-based component of treatment for improving both physical and mental illness. Ensuring health care staff have the necessary competence to support and promote exercise is critical to successful implementation. The Exercise in Mental Illness Questionnaire-Health Professionals Version (EMIQ-HP) was developed to determine the knowledge, attitudes, barriers, and behaviors of health practitioners regarding the role of exercise in the treatment for mental illness. This study aimed to translate and validate the questionnaire into Italian language (EMIQ-HP-IT) and to determine its test-retest reliability. Method: The questionnaire was translated from English to Italian then back translated using an established protocol. To determine the test-retest reliability of the EMIQ-HP-IT, mental health professionals from an Italian psychiatric hospital completed the questionnaire on two separate occasions, seven days apart. Intra-class correlation coefficients (ICC) were calculated for each item. Twenty-five mental health professionals (4 psychiatrists, 9 psychologists, 10 nurses and 2 exercise specialists) completed the EMIQ-HP-IT. Results: Except for two items, ICCs ranged from 0.48 to 0.92. The test-retest reliability of the EMIQ-HP-IT demonstrated comparable results to the English version. Conclusions: The EMIQ-HP-IT is a reliable measure of practitioners' knowledge, attitudes, beliefs, and behaviors regarding exercise interventions for people with mental illness.

European fitness landscape for children and adolescents: updated reference values, fitness maps and country rankings based on nearly 8 million test results from 34 countries gathered by the FitBack network.

OBJECTIVES: (1) To develop reference values for health-related fitness in European children and adolescents aged 6-18 years that are the foundation for the web-based, open-access and multilanguage fitness platform (FitBack); (2) to provide comparisons across European countries. METHODS: This study builds on a previous large fitness reference study in European youth by (1) widening the age demographic, (2) identifying the most recent and representative country-level data and (3) including national data from existing fitness surveillance and monitoring systems. We used the Assessing Levels of PHysical Activity and fitness at population level (ALPHA) test battery as it comprises tests with the highest test-retest reliability, criterion/construct validity and health-related predictive validity: the 20 m shuttle run (cardiorespiratory fitness); handgrip strength and standing long jump (muscular strength); and body height, body mass, body mass index and waist circumference (anthropometry). Percentile values were obtained using the generalised additive models for location, scale and shape method. RESULTS: A total of 7 966 693 test results from 34 countries (106 datasets) were used to develop sex-specific and age-specific percentile values. In addition, country-level rankings based on mean percentiles are provided for each fitness test, as well as an overall fitness ranking. Finally, an interactive fitness platform, including individual and group reporting and European fitness maps, is provided and freely available online (www.fitbackeurope.eu). CONCLUSION: This study discusses the major implications of fitness assessment in youth from health, educational and sport perspectives, and how the FitBack reference values and interactive web-based platform contribute to it. Fitness testing can be conducted in school and/or sport settings, and the interpreted results be integrated in the healthcare systems across Europe.

Lower back pain in young climbers: a retrospective cross-sectional study.

Objective: The popularity of sport climbing has been growing since its inclusion in the Olympic Games program, which led to more people practicing it on recreational, amateur, and professional levels. Strenuous climbing training sessions and competitions might lead to frequent and serious musculoskeletal injuries and complaints among competitive climbers. This study aimed to investigate the prevalence of low back pain (LBP) and to explore the influence of various risk factors on LBP in adolescent climbers. Methods: The sample included 180 competitive climbers (46.6% males) aged 13-19 years competing in under-16 (48.3%) or under-20 categories. Data collection was carried out using the Nordic Musculoskeletal Questionnaire (NMQ) and the Graded Chronic Pain Scale (GCPS). Results: A total of 74.4% of the entire sample of participants (male = 75%; female = 74%) reported lower back complaints throughout the past twelve months, and only 15.5% during the last seven days. A major part of complaints was classified as low intensity-low disability (Grade I, 62.8%; male = 72.6%; female = 54.2%). Under-20 competitors reported a small but significantly higher percentage of almost all NMQ measures compared to under-16 athletes. Conclusions: This study found a relatively high prevalence of LBP, although complaints were of limited severity and did not affect climbers' regular training practice. Moreover, climbers did not differ in LBP prevalence according to sex, while climbers from the older age group reported higher complaints and seeking medical attention than younger climbers. Future studies should prospectively monitor the influence of climbing on LBP in youth climbers.

Effects of self-selected versus motivational music on lower limb muscle strength and affective state in middle-aged adults.

Background: Strength training plays a crucial role in promoting healthy ageing and music might affect how individuals perform and perceive strength exercises. This study aimed to investigate the effects of self-selected music (SSM) on muscle strength and affective states during maximal isometric contractions on a customized leg extension. Methods: Twenty-six healthy middle-aged males (50.8 ± 8.4 years) performed maximal and endurance isometric strength tests under three different conditions: SSM, motivational music (MM), and control condition (CC). Peak force and Rate of Force Development (RFD) were assessed during the maximal isometric strength test. The isometric endurance test evaluated the mean force and a fatigue index. Moreover, Felt Arousal Scale (FAS) was administered before the strength protocol, whereas the Rate of Perceived Exertion (RPE) and Feeling Scale (FS) at the end of it. Results: Mean force was significantly higher in the SSM (507.3 ± 132.2 N) than MM (476.3 ± 122.4 N, p < 0.01) and CC (484.6 ± 119.2 N, p = 0.03). FAS was significantly higher in the SSM (4.0 [1.3] than MM (3.0 [2.3], p < 0.01) and CC (3.0 [1.3], p < 0.01) conditions. FS was significantly higher in the SSM (4.0 [2.0] than MM (3.0 [1.3], p < 0.01) and CC (3.0 [1.3], p < 0.01) conditions. No significant differences were found for peak force, RFD, fatigue index, and RPE. Conclusions: Listening to SSM seems to influence isometric endurance strength performance in middle-aged adults positively. Moreover, listening to SSM might improve individuals' affective states without affecting the level of perceived exertion.

Effects of a multimodal physical exercise program on physical and mental health indicators in males with substance use disorder / Efeitos de um programa multimodal de exercícios físicos na saúde física e mental em homens com dependência química

INTRODUCTION: Substance use disorder (SUD) is seen as a serious and growing public safety and health problem worldwide. Long-term sequelae may involve permanent damage to physical fitness, body balance, and coordination skills, with a severe motor, functional, and emotional consequences. OBJECTIVE: To verify the effect of 16 sessions of a multimodal physical exercise program on physical fitness, body balance, and internalized stigma of inpatients for the treatment of Substance use disorder. METHODS: Forty-three males with Substance use disorder (aged 33.9±12.4 years) were divided into an Intervention Group (IG, n=21) and Control Group (CG, n=22). The IG was submitted to eight weeks of training with physical exercises. Participants were submitted to the evaluation of internalized stigma, body balance, agility, and flexibility, before and after the intervention period. RESULTS: Positive results were observed in physical fitness (agility, p=0.001) and body balance variables (center of pressure path with closed eyes, p=0.050, and ellipse area with closed eyes, p=0.031). The time of substance use correlated with lower performance in agility and body balance tests. CONCLUSION: The data seem to support the potential benefit of physical exercise as an adjunct in Substance use disorder rehabilitation process, particularly for physical fitness and body balance variables.

INTRODUÇÃO: A dependência química (DQ) é vista como um problema grave e crescente de saúde e segurança pública ao redor do mundo. As sequelas a longo prazo podem envolver prejuízos à aptidão física, equilíbrio corporal e capacidades coordenativas, com consequências motoras, funcionais e emocionais severas. OBJETIVO: Verificar o efeito de 16 sessões de um programa multimodal de exercícios físicos na aptidão física, equilíbrio corporal e estigma internalizado em pacientes internados para o tratamento de dependência química. MÉTODOS: Foram avaliados 43 homens com dependência química (idade 33,9±12,4 anos), divididos em Grupo Intervenção (GI, n=21) e Grupo Controle (GC, n=22). O GI foi submetido a oito semanas de treinamento com exercícios físicos. Os participantes foram submetidos à avaliação do estigma internalizado, equilíbrio corporal, agilidade e flexibilidade, antes e após o período de intervenção. RESULTADOS: Resultados positivos foram observados na aptidão física (agilidade, p=0,001) e variáveis do equilíbrio corporal (centro de pressão com os olhos fechados, p=0,050, e área da elipse com os olhos fechados, p=0,031). O tempo de uso de substância correlacionou-se com os piores desempenhos nos testes de agilidade e equilíbrio corporal. CONCLUSÃO: Os dados parecem corroborar os potenciais benefícios do exercício físico como um adjuvante no processo de reabilitação da dependência química, particularmente para as variáveis da aptidão física e equilíbrio corporal.

Promoting Physical Activity during School Closures Imposed by the First Wave of the COVID-19 Pandemic: Physical Education Teachers' Behaviors in France, Italy and Turkey.

The COVID-19 pandemic has drastically reduced physical activity (PA) behaviors of many people. Physical education (PE) is considered one of the privileged instruments to promote youths' PA. We aimed to investigate the effects of lockdown on PE teachers' behaviors promoting their students' out-of-school PA and differences between three European countries. A sample of 1146 PE teachers (59.5% females) from France, Italy, and Turkey answered an online questionnaire about guiding students to engage in out-of-school PA, helping them to set PA goals, encouraging in self-monitoring PA, the pedagogical formats of these behaviors and feedback asked to students. RM-MANCOVAs were performed with a two-time (before and during the lockdown), three country (France, Italy, Turkey), two gender factorial design, using teaching years and perceived health as covariates. A significant multivariate main effect time × country × gender (p < 0.001) was reported for the behaviors promoting students' PA, with French and Italian teachers increasing some behaviors, while Turkish teachers showing opposite trends. Significant multivariate main effects time × country were found for formats supporting the behaviors (p < 0.001) and for asked feedback formats (p < 0.001). The massive contextual change imposed by lockdown caused different reactions in teachers from the three countries. Findings are informative for PA promotion and PE teachers' education.

Factors Influencing Weight Loss Practices in Italian Boxers: A Cluster Analysis.

It is common practice in combat sports that athletes rapidly lose body weight before a match, by applying different practices-some safer and others possibly dangerous. The factors behind the choice of practices utilised have not been fully studied. This study aimed to investigate the weight loss strategies used by Italian boxers and to look at the difference between higher and lower risk practice adaptors. A modified version of a validated questionnaire has been sent to 164 amateur (88%) and professional (12%) boxers by email. A heatmap with hierarchical clustering was used to explore the presence of subgroups. Weight loss strategies were used by 88% of the athletes. Two clusters were found, defined by the severity of weight loss behaviours. Professional fighters, high-level athletes and females were more represented in Cluster 2, the one with more severe weight-loss practices. These athletes were characterised by a higher weight loss magnitude and frequency throughout the season and reported being more influenced by physicians and nutritionists, compared with the boxers in Cluster 1. Not all the weight loss practices are used with the same frequency by all boxers. The level of the athlete and the boxing style have an influence on the weight-cutting practices.

Multicomponent Exercise Training Improves Gait Ability of Older Women Rather than Strength Training: A Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to compare the effects of multicomponent and strength training programs on dynamic balance, functional capacity, and gait ability in older women. METHODS: Thirty individuals (67 ± 4.3 years; 30.6 ± 3.9 kg/m2) were trained for 12 weeks (3 times per week), following multicomponent (MG: exercises focusing on agility, balance, muscle strength, and aerobic) and strength programs (SG: lower limbs strength exercise). RESULTS: Peak torque of hip flexors (p=0.020) and extensors (p=0.009) and knee flexors (p=0.001) of SG was greater than that of MG at posttraining. In addition, both groups increased peak torque of knee extensors (p=0.002) and plantar extensors with higher effect size for SG (d = -0.41 and -0.48), whereas MG presented higher effect size for plantar flexors muscles (d = -0.55). Only the SG improved the rate of torque development of knee extensors (29%; p=0.002), and this variable was also greater to SG than MG at posttraining (106%). The SG and MG improved dynamic balance although SG presented higher effect size (d = 0.61). Both groups improved the performance on 30 s sit to stand test (p=0.010) with higher effect size for MG (d = -0.54). Only the MG improved the stride length (4%; p=0.011) and gait speed (10%; p=0.024). In addition, the groups improved toe clearance (p=0.035) and heel contact (p=0.010) with higher effect sizes for MG (d = -0.066 and 1.07). CONCLUSION: Strength training should be considered to increase muscle function and dynamic balance in older women, whereas multicomponent training should be considered to increase functional capacity and gait ability in this population.

Test-retest reliability of the Italian version of the M-BACK questionnaire to assess the barriers, attitudes, confidence, and knowledge of mental health staff regarding metabolic health of psychiatric patients.

OBJECTIVES: The Metabolic-Barriers, Attitudes, Confidence, and Knowledge Questionnaire (M-BACK) was developed to determine the barriers, attitudes, confidence, and knowledge of mental health practitioners regarding the metabolic health of patients in order to determine the efficacy of targeted training interventions. This study aimed to validate the Italian version of M-BACK questionnaire (M-BACK-IT) and to determine the test-retest reliability. METHODS: The M-BACK questionnaire was translated into Italian and back-translated using an established protocol. In order to determine the test-retest reliability of the instrument, mental health professionals were recruited from a private psychiatric hospital located in northeast Italy and completed the questionnaire on two separate occasions, seven days apart. Intraclass correlation coefficients (ICC) were calculated for the total score, as well as each of the four M-BACK domains. RESULTS: Thirty mental health professionals (4 psychiatrists, 9 psychologists, 12 nurses, and 5 exercise specialists) completed the M-BACK-IT. ICCs ranged from 0.58 to 0.94. CONCLUSIONS: The test-retest reliability of the M-BACK-IT demonstrated comparable results to the English version. The M-BACK-IT is a reliable measure to assess key elements of practitioners' perceptions of the barriers, their knowledge, attitudes, and confidence regarding metabolic monitoring and intervention in people with mental illness.

Postural Control of People in treatment for substance use disorder

Abstract Aims: One of the common sequelae of chronic abuse of alcohol and/or illicit drugs is the impairment of body balance control, caused by long-term neurological damage. This study aimed to investigate the postural control of individuals hospitalized for the treatment of substance use disorder (initial phase) and to compare the results obtained by a control group. Method: For this, One-hundred fourteen individuals hospitalized for the treatment of substance use disorder and eighty-eight healthy controls, all males, were analyzed. Body mass, height, and waist circumference were measured. Were performed a balance test in a static upright position with feet side by side using a plantar pressure platform. Results: Individuals with substance use disorder have shown significantly lower results on body balance compared with controls. Individuals with chemical dependence showed balance results open-eyes, similar/lower than control subjects with close-eyes. Still, those who used only alcohol or alcohol combined with other illicit drugs presented worse results. Finally, impairments in body balance variables showed a significant correlation with age and substance time of use. Conclusion: Even in the early stage of treatment, substance use disorder considerably impairs the balance of the investigated men. The worst results were found in alcohol-dependents (alcohol alone or alcohol combined with other drugs).

Estigma internalizado de indivíduos em tratamento para dependência química e sua relação com a prática de atividade física / Stigma internalized by individuals in treatment for substance dependence and its relationship with physical activity / Estigma internalizado de individuos en tratamiento para dependencia química y su relación con la práctica de actividad física

Indivíduos com dependência química tendem a ser estigmatizados e, uma vez que este estigma é internalizado, podem ocorrer prejuízos na adesão ao tratamento e a reinserção social. O objetivo do estudo é analisar o estigma internalizado de indivíduos em tratamento para dependência química e sua relação com a prática de atividade física. Para tanto, 106 indivíduos com dependência química responderam a questionários sobre estigma internalizado e prática de atividade física. Os dados foram tratados com estatística descritiva e análises de correlação. O estigma internalizado mostrou-se em geral elevado, com maiores pontuações para Alienação, Percepção de discriminação e Evitação social. Foi verificada correlação significativa inversa entre a prática de atividade física e o estigma internalizado, indicando que a oferta de programas de atividade física na fase de reabilitação pode ser benéfica não apenas para a melhora da condição física, mas também para a redução dos danos psicológicos impostos pela dependência química

Substance-dependent individuals tend to be stigmatized. Internalizing that stigma may result in impairments to their adherence to treatment and social reintegration. This study analyzed stigma internalized by individuals in treatment for substance dependence and its relation to physical activity. Questionnaires on internalized stigma and physical activity were responded by 106 substance-dependent individuals. The data were treated by descriptive statistics and correlation analyzes. Internalized stigma was generally high, with higher scores for Alienation, Perception of Discrimination, and Social Avoidance. Significant inverse correlation was found between physical activity and internalized stigma, indicating that physical activity programs during rehabilitation may not only improve those individuals' physical condition but also reduce the psychological damages imposed by substance dependency

Para ello, 106 individuos con dependencia química respondieron a cuestionarios sobre estigma internalizado y práctica de actividad física. Los datos fueron tratados con estadística descriptiva y análisis de correlación. El estigma internalizado se mostró en general elevado, con mayores puntuaciones para Alienación, Percepción de discriminación y Evitación social. Se verificó una correlación significativa inversa entre la práctica de actividad física y el estigma internalizado, indicando que la oferta de programas de actividad física en la fase de rehabilitación puede ser beneficiosa no solo para mejorar la condición física, sino también para la reducción de los daños psicológicos impuestos por la dependencia química

Effectiveness of individual counseling and activity monitors to promote physical activity among university students.

BACKGROUND: Physical activity (PA) promotion among university students is important to contribute to a lifelong healthy lifestyle. Nevertheless, research in the field is still limited in quantity, quality and generalizability. This study aimed at evaluating the effectiveness of two individual-based strategies for promoting PA among university students in such university contexts where course-based interventions are difficult to implement. METHODS: Thirty-three university students were recruited by means of face-to-face interviews and randomly assigned to three groups. The first group attended individual counselling sessions (based on the social cognitive theory and the transtheoretical model of behavior change) via videoconferencing calls, the second used wearable PA monitors designed to motivate to PA, and the third served as control. Interventions lasted 12 weeks. Measures of weekly PA (self-reported by questionnaires and recorded by ActiGraph-GT3X+ monitors) and the stage of change of participants were collected at baseline (t0), immediately after the 12-week intervention (t1), and after a 3-month follow-up (t2). RESULTS: Students in the individual counselling group increased self-reported energy expenditure between t0 and t1 and maintained this improvement at t2; on the contrary, there was no increase in ActiGraph measures of PA. Progression through stages of changes was observed in the same group at t1, followed by some relapses at t2. No significant differences were found neither in the group of students who used the PA monitors nor in the control group. CONCLUSIONS: Although measures of self-reported PA and stage of change suggest the effectiveness of the counselling intervention, the results obtained with accelerometers are contrasting, probably due to the fact that some types of PA participants engaged in could not be recorder by accelerometers. Further studies are needed to determine the efficacy of individual counselling to promote PA in university students. The autonomous use of PA monitors had no effects on PA behavior. The low participation rate in the study suggests considering carefully the difficulties in motivating this population and in finding low time-consuming strategies to incentive participation.

Perceived treadmill function is correlated with enjoyment of use in trained runners: A user-centred approach.

Physical inactivity, a primary cause of most chronic diseases, has been associated with low levels of physical activity enjoyment. Physical activity enjoyment can be impacted by an individual's experience with exercise equipment. The purpose of this study was to adopt a user-centred approach to determine the relationship between physical activity enjoyment and functionality and usability of four treadmills. A running protocol was completed by 57 trained runners (41 male) on four treadmills. Runners reported enjoyment levels as well as their perceptions about treadmill running surface, controls, safety and stability, physical interaction, learnability of data console and aesthetic appeal. Repeated measures ANOVAs showed significant differences between the treadmills for each variable. Multiple regression analysis reported aesthetic appeal significantly predicted enjoyment of use. Results suggest that adopting a user-centred approach to compare exercise equipment usability and features can correlate with enjoyment and further impact on physical activity adherence.

Short-Term Modifications of Postural Balance Control in Young Healthy Subjects After Moderate Aquatic and Land Treadmill Running.

Postural balance control can be altered by land treadmill (LTM) running. This impairment seems to be related to a disturbance of vestibular and visual information. However, no studies are available on aquatic treadmill (ATM) running. The aim of the present study was to investigate the effect of running at moderate intensity over ATM and LTM on the postural balance control both with opened (OE) and closed (CE) eyes. Center of pressure (CoP) trajectory of 20 healthy subjects was collected on a dynamometric platform before and after a 20-min-long running on ATM and LTM at the same rate of perceived exertion (Borg's scale: 3/10). Heart rate (HR) was recorded every 30 s during running. Stabilogram diffusion analysis (SDA) and sample entropy (SampEn) were calculated to deepen motor control mechanisms. HR values were lower during ATM running with respect to LTM running (p < 0.01). A significant effect of the treadmill factor was detected in the OE condition for the sway path (p < 0.01; ηp 2 = 0.364; Power: 0.879), the sway area (p < 0.01; ηp 2 = 0.324; Power: 0.816), and the ML oscillations (p < 0.01; ηp 2 = 0.390; Power: 0.911) while an effect of the time factor was detected for the ellipse area (p < 0.05; ηp 2 = 0.213; Power: 0.576). However, the effect size for all the parameters ranged from 0.06 (trivial) to 0.48 (small). In the OE condition, the SDA highlighted a significant effect of the treadmill factor on all the short-term diffusion coefficients which negatively influenced the open loop motor control strategies. In the CE condition, SampEn analysis underlined a significant decrease of the CoP regularity after LTM running. Although slight modifications of the mechanisms involved in the postural balance control occurred, ATM and LTM moderate running did not seriously threaten postural balance performance. Therefore, the usage of ATM should be taken into account in all those situations where the well-known advantages of the aquatic environment are priorities.
