Efeitos de um programa de exercícios resistidos periodizado de forma linear na aptidão cardiorrespiratória de idosas

Abstract

Studies relating resistance training to cardiorespiratory fitness, especially in older adults, are scarce. Objective: To verify the effect of a 12-week linearly periodized resistance training program on the cardiorespiratory fitness of older women and to determine if there is a correlation between cardiorespiratory fitness and muscle strength. Method: An uncontrolled intervention study was conducted with 11 older women (69.7 ± 6.5 years) who participated in a 12-week linearly periodized resistance training intervention program with two weekly sessions. Cardiorespiratory fitness (VO₂max) was analyzed using the 1600-meter walking test proposed by Kline et al. (1987), and muscle strength was measured by estimating 1RM using the Epley protocol (1985). Comparisons of pre and post-intervention cardiorespiratory fitness were performed using the paired t-test, and the correlation between cardiorespiratory fitness and muscle strength was assessed using Pearson's correlation coefficient. Results: Slight improvement in the categorical classification of maximum oxygen consumption, but no statistically significant difference in quantitative VO2max values between pre and post-intervention. A positive correlation was observed between muscle strength and cardiorespiratory fitness. Conclusion: Resistance training linearly periodized contributed to the maintenance of cardiorespiratory fitness in elderly women.
