Effects of an 8-week aerobic training program on physical working capacity at heart rate threshold
Abstract
The purpose of this investigation was to determine the effect of an 8-week aerobic training program on physical working capacity at the heart rate threshold (PWCHRT). Nineteen sedentary males and females volunteered for this investigation. The control group consisted of three females and four males (N = 7), while the training group contained four females and eight males (N = 12). The subjects were tested for VO2 MAX and PWCHRT before and after an 8-week aerobic training program. The training consisted of riding a cycle ergometer for 30 minutes at 85% of maximal heart rate (HR) three times per week. Two, 2 x 2 repeated measures ANOVAs were performed for group (control versus training) by time (pre-training versus post-training) for VO2 MAX and PWCHRT. A significant (p $<$ 0.05) group by time interaction for PWCHRT was followed up by using t-tests to analyze the simple main effects. PWCHRT for the training group was significantly greater following the 8-week training program, whereas no change occurred for the control group. The results of this investigation demonstrate that PWCHRT is sensitive to an 8-week training program. The increase in PWCHRT was not accompanied by an increase in VO2 MAX.
