Comparisons of the Physiological and Psychophysical Responses of Handweighted Walking with Three Different Arm Movements in Sedentary Chinese Women
LANGUAGE NOTE | Document text in English; abstract also in Chinese.
The purpose of this study was to compare the physiological and psychophysical responses during six 20-minute walking sessions at 1.34 m sec-1 and 6% gradient, that employed three different arm movements with and without a 0.45kg hand held weight (HHW) per hand, in fifteen sedentary Chinese college females (mean age = 25.1 ± 1.2 years). The sequence of test sessions was randomized and included two normal arm movements, two vigorous arm movements and two moderate arm pumping, walking with and without a 0.45kg HHW per hand. Dependent variables included oxygen uptake (V02, heart rate (HR) and ratings of perceived exertion (RPE). Statistics used included three, 2-way ANOVA (2 loading conditions x 3 different arm movements) and Tukey's post hoc test. Significant differences were noted between protocols involving hand weights and no hand weights (p<0.05) and among the three different arm movements (p<0.01). However, there were no significant differences with post hoc testing and the interaction. Based on lower RPE values, the minimal influence of the natural gait and the increased exercise intensity, walking with a 0.45kg HHW in each hand, while maintaining moderate arm pumping, was a recommended exercise prescription for sedentary Chinese women.
