Steady state exercise yielded a recovery energy expenditure of only 13-71 kJ (3-17 kcal), suggesting that attributing substantial energy expenditure to the recovery period is misleading.
Cross-Sectional (n=16)
Does exercise intensity, mode, and aerobic fitness affect recovery energy expenditure following steady state exercise?
Statements attributing substantial energy expenditure to the post-exercise recovery period may be misleading, as it only amounts to 3-17 kcal for steady state exercise.

This study examined the effects of intensity, mode of exercise, and aerobic fitness on the energy expended during recovery (recovery oxygen consumption, or rec VO2) following steady state exercise. Eight runners (4 males, 4 females; 22-32 yr) walked at 3.2 and 6.4 km X h-1 and ran at 8.1 and 11.3 km X h-1 (18, 33, 50, and 68% peak VO2). All subjects completed 3.2 km of walking or running each session. Eight sedentary adults (4 male, 4 female; 21-33 yr) completed the 6.4 km X h-1 test. For the runners, net rec VO2 for 3.2, 6.4, 8.1 and 11.3 km X h-1 exercise was (X +/- SE) 12.52 +/- 3.00, 29.53 +/- 5.41, 28.64 +/- 2.91, and 44.27 +/- 5.32 ml X kg-1, respectively, for the recovery period (18-48 min). Differences among group means were significant (P less than 0.05), except between 6.4 and 8.1 km X h-1 walking (29.53 +/- 5.41 and 35.09 +/- 9.39 ml X kg-1). Statements attributing substantial energy expenditure to the recovery period may be misleading to people exercising at levels similar to those described in this study, since the recovery energy expenditure only amounted to approximately 13-71 kJ (3-17 kcal).
Brehm et al. (Tue,) conducted a cross-sectional in Healthy adults (n=16). Steady state exercise (walking and running) vs. Different intensities and fitness levels was evaluated on Recovery oxygen consumption (net rec VO2) (p=<0.05). Steady state exercise yielded a recovery energy expenditure of only 13-71 kJ (3-17 kcal), suggesting that attributing substantial energy expenditure to the recovery period is misleading.
