abstract={Encouraging physical activity is a key component of public health. The purpose of this study was to test the hypothesis that interval walking would produce higher oxygen uptake (V?O<SUB>2</SUB>) and similar enjoyment responses during and following exercise compared to continuous walking. Ten healthy adults (4 women, 6 men; mean age = 24 ¡À 5 years) completed the following 3 walking bouts in counterbalanced order and equated for total volume (90 MET¡¤min): 1) 30 min of low-moderate continuous walking (3 METs; ~ 4.8 km/h), 2) 24 min and 24 s of interval walking (IW1) with cycles of 30 s:60 s of high-moderate (5 METs; ~ 6.4 km/h):low-moderate intensities, and 3) 26 min and 20 s of interval walking (IW2) with cycles of 30 s:120 s of high-moderate:low-moderate intensities. Accumulated O<SUB>2</SUB> uptake during exercise was higher during IW2 (28,232 ¡À 2,782 mL) compared to IW1 (26,561 ¡À 2,685 mL; p = 0.03) and continuous walking (24,500 ¡À 2,427 mL; p = 0.001), and higher during IW1 than during continuous walking (p = 0.001). EPOC over 20 min was higher after IW1 (1,268 ¡À 117 mL O<SUB>2</SUB>) compared to continuous walking (892 ¡À 73 mL; p = 0.04); the 2 interval walking protocols were not different (IW2: 1,174 ¡À 178 mL; p > 0.05). Exercise enjoyment before, during, and after exercise did not differ among the walking protocols (all p > 0.05). Interval walking elicited greater V?O<SUB>2</SUB> and EPOC in shorter total durations of exercise compared to continuous walking of a similar enjoyment and volume.},
