Abstract

This study evaluated the effects of continuous and intermittent walking on oxygen uptake (V̇O2), Rating of Perceived Exertion (RPE), and enjoyment during exercise, and excess post-exercise oxygen consumption (EPOC) and enjoyment after exercise. Methods: Four women and six men (mean ± SD) aged 24 ± 5 years completed four walking bouts in counterbalanced order matched for volume (90 metabolic equivalent [MET]-min): 1) one, 30-min continuous walking (CW) bout at moderate-intensity (3 METs; ≈4.8 km/h), 2) three, 10-min intermittent walking bouts (IW) at moderate-intensity (3 METs; ≈4.8 km/h) separated by 20 min of rest, 3) three, 8-min interval walking (IIW1) bouts at moderate-intensity (5 METs; ≈6.4 km/h: 3 METs; ≈4.8 km/h) separated by 20 min of rest, and 4) three, 8-min 40-s interval walking (IIW2) bouts at moderate-intensity (5 METs; ≈6.4 km/h: 3 METs; ≈4.8 km/h separated by 20 min of rest. VO2 was measured during exercise and EPOC was measured for 20 minutes post exercise. RPE was assessed during exercise and enjoyment of exercise was assessed during- and post exercise. Results: Average accumulated O2 uptake during exercise and EPOC in IW (39,186 ± 4,290 mL; EPOC: 2,582 ± 339 mL), IIW1 (36,964 ± 3,789 mL; EPOC: 3,365 ± 507 mL), and IIW2 (35,804 ± 3,979 mL; EPOC: 3,083 ± 339 mL) were higher (all p < 0.05) than CW (24,500 ± 2,427 mL; EPOC: 892 ± 73 mL). There were no differences in average RPE (p = 0.17) or average enjoyment (all p ≤ 0.05) across time points or between conditions. Conclusion: In healthy, young adults, moderate-intensity intermittent walking and intermittent interval walking protocols resulted in higher energy expenditure during and after exercise – as reflected by accumulated VO2 uptake and EPOC, respectively – compared to moderate-intensity continuous walking matched by MET-min with no difference in enjoyment or RPE.
