Due to missing data, n-sizes ranged: Male = 10–11, Female = 18–21.
Resistance settings ranged from 0–119 clicks.
The Wilcoxon Signed-Rank Test indicated that energy expenditure (kcal/hour) and heart rate (bpm) while using the elliptical device were both significantly greater than energy expenditure and heart rate, respectively, during sedentary sitting for the total sample (p’s < 0.0001), males (p’s < 0.01), and females (p’s < 0.0001).
Borg’s Rating of Perceived Exertion scale: 11 = “fairly light.”28
IQR, interquartile range.
p, adjusted p-values controlling for BMI (18.5–24.9 vs. 25–34.9) from Cochran-Mantel-Haenszel mean score test. Results from Wilcoxon rank-sum tests (unadjusted for BMI) showed a similar pattern of results to the adjusted analyses.
