Abstract

<b>Background:</b> This study investigated health related effects of exercise programmes with exercise sessions of similar intensity but different frequency and duration. <b>Methods:</b> Thirty four overweight women were randomised into either long bout (LB) or short bout (SB) exercise groups. Participants performed an 8-week supervised programme, with the LB group exercising for 75 minutes twice per week, and the SB group for 30 minutes on five days of the week. <b>Results:</b> The LB group completed 16 sessions at a HR of 127 ± 1 beat·min-1 and the SB group completed 40 sessions at a HR of 126 ± 1 beat·min-1. Weekly energy expenditure of exercise was not different between groups (LB group, 5.64 ± 0.34 MJ; SB group, 5.83 ± 0.23 MJ). Training significantly (p<0.05) increased measures of cardiorespiratory fitness, decreased waist circumference, insulin resistance, and diastolic blood pressure. The group x time interaction was not significant for any of these factors, indicating that responses to exercise training did not differ between the SB and LB groups. <b>Conclusions:</b> Health related outcomes of exercise programmes with similar energy expenditure are independent of frequency and duration of exercise sessions. This provides individuals with a degree of flexibility in exercise programme planning.
