he aging process is related to numerous physiological changes that interfere with motor performance and general health status.1 Between 50 and 80 years of age, there is an annual loss of 1% of lean body mass.2, 3 This gradual loss of muscle mass and strength over the years is known as sarcopenia,4 and it has an impact on the health of the elderly due to the functional losses caused by gait and balance, increasing the risk of falls and contributing to the reduction of physical and functional independence.5 However, the practice of regular physical exercises

BACKGROUND: Activities in the aquatic environment can be an interesting alternative of physical exercise for the elderly, due to several properties of water, which can favor the physiological, metabolic, perceptive, and musculoskeletal effects. The aim of this study was to compare the effects of performing two hydrogymnastic class methodologies on the functional capacity and flexibility in elderly women. METHODS: Ninety women, aged 55-70 years, were divided into three groups, the control group (CG; N.=30) who did not exercise during the 12 weeks, experimental group 1 (EG1; N.=30), who performed water gymnastics classes with emphasis on lower limb exercises for 12 weeks, and experimental group 2 (EG2; N.=30), who performed conventional hydrogymnastics classes for 12 weeks. The volunteers were evaluated through the 30-second chair stand (30CST), 2-minute step test (2MST), timed up and go (TUG), static balance (SB) and chair sit-and-reach (CSR) tests. RESULTS: In the intragroup comparison, there were significant improvements in the performance of 30CST tests (F=5.5, P=0.022), TUG (F=19.3, P
