Random Effects
SD intercept (95% CI)	5.13 (5.02, 5.24)			5.01 (4.90, 5.12)			5.04 (4.93, 5.15)			4.85 (4.73, 4.96)
SD error 95% CI	6.94 (6.88, 6.99)			6.83 (6.77, 6.89)			6.81 (6.75, 6.87)			6.63 (6.57, 6.70)

SD intercept: SD of the individual variance of the random part of the model; SD error: standard error of linear mixed model; CI = confidence interval. Body fat%, waist circumference, and resting heart rate were normalized by fitness.
