High-intensity interval running is perceived to be more enjoyable than moderate-intensity continuous exercise: Implications for exercise adherence

The aim of this study was to objectively quantify ratings of perceived enjoyment using the Physical Activity Enjoyment Scale following high-intensity interval running versus moderate-intensity continuous running. Eight recreationally active men performed two running protocols consisting of high-intensity interval running (6 x 3 min at 90% VO2max interspersed with 6 x 3 min active recovery at 50% VO2max with a 7-min warm-up and cool down at 70% VO2max) or 50 min moderate-intensity continuous running at 70% VO2max. Ratings of perceived enjoyment after exercise were higher (P <>P <>P <>VO2 (71 ± 6 vs. 73 ± 4%VO2max), total VO2 (162 ± 16 vs. 166 ± 27 L) or energy expenditure (811 ± 83 vs. 832 ± 136 kcal) between protocols. The greater enjoyment associated with high-intensity interval running may be relevant for improving exercise adherence, since running is a low-cost exercise intervention requiring no exercise equipment and similar relative exercise intensities have previously induced health benefits in patient populations.
