Conclusions The current evidence , from cross-sectional and prospect i ve cohort studies , supports that physical activity of any bout duration is associated with improved health outcomes , which includes all-cause mortality .
Purpose This study aim ed to conduct a systematic literature review to determine whether physical activity episodes of < 10 min in duration have health-related benefits or , alternatively , if the benefits are only realized when the duration of physical activity episodes is ≥10 min .
The Effects of Single Long and Accumulated Short Bouts of Exercise on Cardiovascular Risks in Male Japanese Workers: A Randomized Controlled Study
The aim of this study was to determine whether accumulated short bouts of exercise can achieve the same cardiovascular benefits as a single long bout of exercise in sedentary male Japanese workers and to compare the programs ’ relative effects on oxidative stress . Twenty-three sedentary male workers were r and omly assigned into 2 different exercise programs : a Long-bout group , which performed a single period of continuous exercise ( Long-bout group : 30 min × 1 ) 3 d per week , and a Short-bouts group , which performed 3 short bouts of exercise ( Short-bouts group : 10 min × 3 ) 3 d per week . Cardiovascular risk factors , including the plasma thiobarbituric acid-reactive substances ( TBARS ) level , were examined at baseline and after both 10 and 20 wk . In the Long-bout group , waist circumference and maximum oxygen uptake ( VO2max ) significantly improved after 20 wk . The Short-bouts group demonstrated significant increases in VO2max after 10 weeks and in HDL-C after 20 wk . Plasma TBARS significantly decreased after 20 weeks in the Long-bout group and tended to decrease ( but not significantly ) in the Short-bouts group . These results indicate that accumulated short bouts of exercise are an effective option , especially for busy workers , for incorporating exercise into one ’s lifestyle
