Effect of pre-season and in-season training on anthropometric variables, somatotype, body composition and body proportion in elite basketball players.

The aims of the study were: 1) to evaluate the changes in anthropometric variables, body composition, somatotype and body proportions of elite basketball players throughout the pre-season period; 2) to evaluate the changes in anthropometric variables, body composition, somatotype and body proportions of elite basketball players throughout the in-season period; and 3) to observe if the age and position influenced the variables analyzed. A total of 17 players belonging to the men's ACB league team competing in the Euroleague (age = 23.42 ± 5.28 years-old) participated in the study. The players underwent an anthropometric measurement before and after the pre-season, as well as four evaluations throughout the in-season. Anthropometric indices, somatotype components according to Heath and Carter, and adiposity were calculated. The results show that during the pre-season, body mass, BMI, sum of 6 and 8 skinfolds, waist/hip ratio, adipose tissue (kg), adipose tissue percentage, and endomorphy decreased, while ectomorphy increased. However, no significant changes were found in the variables analyzed throughout the season; except for endomorphy, which increased along the in-season. Playing position and age did not have a significant influence on the changes in the anthropometric variables throughout the pre-season and the in-season. In conclusion, while changes in the anthropometric variables in the pre-season were observed, these remained the same during the in-season.

Resistance training effects on healthy postmenopausal women: a systematic review with meta-analysis.

The aim of this systematic review with meta-analysis was to evaluate the effects of resistance training on physical fitness, physiological variables and body composition of postmenopausal women. The present systematic review was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement and was registered in PROSPERO. A total of 12 studies were included. The literature search was performed in PubMed, Web of Science and EBSCO. Randomized control trials were included. Two blinded investigators performed the search, study selection and data collection, and assessed the quality and risk of bias. A random-effects model was used for all analyses. Compared to the control group, resistance training produced a significant improvement in maximal oxygen volume (standardized mean difference [SMD] = 2.32, p < 0.001), lower extremity strength (SMD = 4.70, p < 0.001) and upper extremity strength (SMD = 7.42, p < 0.001). The results obtained in the systematic review and meta-analysis confirm the benefits of resistance training on physical fitness in postmenopausal women, although there is more debate regarding its influence on bone mineral density, and anthropometric and derived variables. This work provides a solid starting point for promoting resistance training at a frequency of 3 days per week, in 60-min sessions, with the aim of improving parameters directly related to quality of life, functionality and disease prevention of postmenopausal women.

Self-perception of dual career barriers and athletic identity in student-athletes with disabilities according to disability type and level of professionalization.

The objective of this study was to analyze the perceived barriers to dual career success and athletic identity of student-athletes according to disability type and level of professionalization. The final sample consisted of 203 student-athletes with disabilities from five European countries. The questionnaires used were ESTPORT, EBBS and AIMS. Depending on disability type, it was found that student-athletes with hearing and physical impairment showed the highest difficulty in reconciling sports and studies (p = 0.001); that student-athletes with a hearing impairment showed the highest score in the barrier 'the cost of education is high' (p = 0.023); that student-athletes with a physical impairment had the highest scores in the barrier 'Exercise tires me' (p = 0.013); that student-athletes with cerebral palsy showed the highest scores in the barrier 'I do not have enough university/educational institution support' (p = 0.014) and 'Exercise facilities do not have convenient timetables for me' (p = 0.001). Depending on sports professionalization level, semi-professional student-athletes showed the highest values in the barrier 'the university/educational institution is far from my training center' (p = 0.040); while professional student-athletes had the highest score in the barrier 'exercise takes too much time from family responsibilities' (p = 0.034). In most of the variables related to identity as athletes, professional student-athletes showed the highest values, followed by semi-professional athletes (p = 0.043- < 0.001). In conclusion, the self-perception of barriers is quite relevant, with differences arising from disability type and level of professionalization, whereas the identity as an athlete is only different according to the level of professionalization.
