Functional fitness and fall risk in older adults practitioners or non-practitioners of Tai Chi.

Tai chi is a fundamental tool that has a significant influence on balance, motor function and fear of falling among older adults. The objective of the study was to verify functional fitness and fall risk in older adults (OA) practitioners and non-practitioners of Tai Chi. An ex-post-facto study was carried out in practicing and non-practicing OA of Tai chi. The sample selection was non-probabilistic (convenience). Thirty-one adults with an age range of 65 to 80 years were studied. Two study groups were formed: Group practicing Tai Chi [GPT (n= 15 subjects)] and Group not practicing Tai Chi [GNPT (n= 16 subjects)]. Age, weight, height, waist circumference were assessed. Body mass index (BMI) and fat mass (FM) were calculated. Five functional fitness tests were assessed: biceps curl (30sec), Chair stand (30sec), agility (sec), 2min walk (#rep) and 6min-1 walk (m). Fall risk was measured using a 13-item scale. The GPT showed better performance in all five functional fitness tests (biceps curl, Chair stand, agility, 2min gait and 6min walk) compared to the GPT. The effect size (ES: ~0.20 to 0.48) and Cohen's d (~ 0.39 to 1.10) between both groups were medium to large. There were also differences between the mean values in fall risk between both groups (GNPT: 2.1±1.7points and GNPT: 4.7±1.9points, p<0.05). This study demonstrated that the group of OA practicing Tai Chi presented better levels of functional fitness and less risk of falling in relation to their counterparts who did not practice Tai Chi. These results suggest including this type of old-time exercise in physical activity programs that promote functional fitness wellness and fall prevention among OA.

Systematic review of the anthropometric profile of female futsal players 2010-2020.

The objective was to summarize the scientific literature on the anthropometric characteristics of female futsal players. A systematic review documentary study was carried out. SCOPUS, PUBMED and SCIELO databases were used to search for information on primary studies related to the anthropometric profile of women's indoor soccer (elite and non-elite). The keywords used were: futsal, female, anthropometry. The range of years for the search was from 2010 to 2020. To analyze anthropometric differences, two groups were formed: group A: elite and group B: non-elite. 31 primary studies were identified, 22 (71%) in Scopus, 5 (16.1%) in PUBMED and 4 (12.9%) in SCIELO. Three publication languages were considered (English, Spanish and Portuguese) and 6 countries were identified (Brazil, Spain, Iran, Turkey, Venezuela and Italy). Players in the elite group evidenced higher weight, height, and BMI relative to their non-elite counterparts. Discrepancy in anthropometric characteristics between elite and non-elite players was verified. These results suggest that in order to participate in competitions at the highest level in women's futsal, they should have greater weight, height and BMI than their non-elite counterparts.
