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

Abstract

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 (6×3 min at 90% VO2max interspersed with 6×3 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<0.05) following interval running compared with continuous running (88±6 vs. 61±12) despite higher (P<0.05) ratings of perceived exertion (14±1 vs. 13±1). There was no difference (P<0.05) in average heart rate (88±3 vs. 87±3% maximum heart rate), average 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. © 2011 Taylor and Francis.
