Comparação das respostas fisiológicas e perceptuais obtidas durante caminhada na esteira em ritmo autosselecionado entre os sexos

The aim of this study was to compare physiological and perception responses between genders during treadmill walking at self-selected pace. 17 men and 17 women aged 23.32 ± 3.06 yr were investigated: (I) anthropometric assessment and incremental exhaustion test, (II) a 20-minute walking bout on treadmill at their self-selected pace. The independent t test was utilized to verify any gender differences, with a level of p < 0.05. The self-selected walking pace was significantly greater in men than women (1.65 ± 0.18 and 1.50 ± 0.12 m·sec-1, respectively), and consequently resulted in higher absolute VO2 for men compared to women (21.2 ± 5.5 and 18.3 ± 2.7, respectively). However, both genders self-selected a similar relative exercise intensity %VO2max (37.5 ± 10.7 and 40.3 ± 7.2 for men and women, respectively). The subjective perceived exertion (SPE) did not differ between genders (10.2 ± 1.0 and 9.8 ± 1.2 for men and women, respectively). The results of the present study demonstrated that regardless of gender, physically active young adults self-selected a similar relative exercise intensity that reflected in similar SPE. Furthermore, gait at self-selected intensity was insufficient to improve cardiorespiratory fitness in this sample.
