Table 1.
Characteristics of study participants and mean energy expenditure during each activity. Data are expressed as mean ± SD. For all activities, percent increase above resting values is shown in parentheses. Values with different letters indicate a significant difference in energy expenditure. Values with the same letter were not significantly different.
