ABSTRACT
ABSTRACT The Table Tennis game does not involve large displacements by the practitioner in the environment, a characteristic that can promote greater safety for the elderly in locomotor terms. In addition, it needs coordination, agility, speed of reaction, dynamic balance, which have been the focus of current recommendations of physical activity for the health of adults and the elderly. The aim of this study is to investigate the effects of table tennis practice on physical and functional fitness in the elderly. This quasi-experimental research with a parallel and controlled design. The sample consisted of 16 elderly people, allocated 8 in the experimental group (EG) and 8 in the control group (CG). The research lasted 18 weeks, with 2 weeks of evaluation (initial and final) and 16 weeks of intervention. Physical fitness assessments were carried out using the agility and balance and functional fitness tests. In the intra-group comparison (pre-post intervention), EG showed a significant difference for the variable agility (pre: 15.6 ± 1.2 s; post: 14.7 ± 0.7 s). Also, the EG showed a reduction in Area (pre: 11.00±3.32 cm2; post: 6.52±3.06 cm2), AP Amplitude (pre: 4.92±2.77 cm; post: 3.28±0.58 cm) and ML speed (pre: 2.77±1.07 cm/s; post: 2.31±1.03 cm/s) in the Tandem posture with eyes open. Our findings highlight the importance of a Table Tennis program, administered twice a week and consisted of low to moderate intensity activities, to promote a beneficial effect on the agility and balance of physically active elderly people.
RESUMO O jogo de Tênis de Mesa não envolve grandes deslocamentos do praticante no ambiente, característica que pode promover maior segurança ao idoso em termos locomotores. Além disso, precisa de coordenação, agilidade, velocidade de reação, equilíbrio dinâmico, que têm sido foco das atuais recomendações de atividade física para a saúde de adultos e idosos. O objetivo deste estudo é investigar os efeitos da prática de tênis de mesa na aptidão física e funcional de idosos. Esta pesquisa apresenta delineamento quase experimental com um desenho paralelo e controlado. A amostra foi composta por 16 idosos, alocados 8 no grupo experimental (GE) e 8 no grupo controle (GC). A pesquisa teve duração de 18 semanas, sendo 2 semanas de avaliação (inicial e final) e 16 semanas de intervenção. As avaliações da aptidão física foram realizadas por meio dos testes de agilidade e equilíbrio e aptidão funcional. Na comparação intragrupo (pré-pós intervenção), o GE apresentou diferença significativa para a variável agilidade (pré: 15,6 ± 1,2 s; pós: 14,7 ± 0,7s). Além disso, o GE apresentou redução na Área (pré: 11,00±3,32 cm2; pós: 6,52±3,06 cm2), Amplitude AP (pré: 4,92±2,77 cm; pós: 3,28±0,58 cm) e velocidade ML (pré: 2,77±1,07 cm/s; pós: 2,31±1,03 cm/s) na postura Tandem com os olhos abertos. Nossos achados destacam a importância de um programa de Tênis de Mesa, administrado duas vezes por semana e composto por atividades de baixa a moderada intensidade, para promover um efeito benéfico na agilidade e equilíbrio de idosos fisicamente ativos.

Background: Studies have demonstrated the positive effects of physical activity on cardiovascular risk factors. Longitudinal studies using modeled trajectories are necessary to understand patterns of physical activity and association with cardiovascular risk factors. Objective: To analyze the association between sports practice in young people and current physical activity with the trajectory of cardiovascular risk factors in workers at a public hospital. Methods: Four hundred and seventeen workers was followed for four years reporting Physical Activity, health status, lifestyle behaviors and socio-demographic characteristics. Group-based trajectory modeling identified the trajectories of PA and associations with time-stable and time-varying covariates. We considered a range of sociodemographic and health and lifestyle factors as potential covariates. Results: The results shows the association between participation in sports activities in youth and current physical activity and trajectories of cardiovascular risk, adjusted for sex and age (p < 0.05). Adults who reported having played sports in their youth and are currently active have a lower risk of having a history of obesity and low HDL-c than workers who did not play sports in their youth and are currently sedentary 0.690 (0.565-0.844) obesity, 0.647 (0.500-0.837) low HDL-c. Conclusion: The practice of sports in youth and current physical activity is a protective factor against the trajectory of obesity and low HDL-c, mainly in female workers. Programs to encourage the practice of physical activity should be carried out in order to reduce cardiovascular risk factors and prevent chronic diseases in workers.
