INTRODUCTION:
Changes in strength and functional capacity due to aging can be improved through physical exercises practice such as strength training and hydrogymnastics.
OBJECTIVE:
To compare the strength and functional capacity among elderly individuals who practice strength training, hydrogymnastics and non-practitioners of physical exercises.
METHODS:
Descriptive cross-sectional study with voluntary non-probability sampling. The study included 36 elderly (63.6±4.1 years): 12 strength training practitioners, 12 hydrogymnastics practitioners and 12 non-practitioners of physical exercises. The level of physical activity was assessed by the International Physical Activity Questionnaire (IPAQ). The maximum force was performed by the one maximum repetition test (1RM) in upper and lower limbs. Functional capacity was evaluated by tests of rising from a chair in 30 seconds and usual maximum walking speed. One Way ANOVA test with post hoc Bonferroni was used to compare the dependent variables between the groups with α= 0.05.
RESULTS:
All groups were classified as active. The strength training group had the highest values of maximum strength when compared to hydrogymnastics group and non-practitioners of physical exercises (p≤0.01). In addition, hydrogymnastics practitioners and non-practitioners of physical exercises groups showed no differences in maximum strength (p=1.0). As for the chair lifting test, no differences were observed between groups (p=0.07) and the same was observed in habitual (p=0,06) and maximum (p=0,22) walking speed test.
CONCLUSION:
The strength training was more effective for increasing strength, but active lifestyle is sufficient to maintain functional capacity.
