Energy expenditure for LTPA (kcal·week^−1)	1187 ± 1668^†	2320 ± 2707
Energy expenditure for LTPA (kcal·week^−1·kg^−1)	14.1 ± 19.5^†	30.2 ± 36.0
PWC85%HRmax (W)	133.5 ± 41.1^‡	157.0 ± 36.6
PWC85%HRmax/kg (W·kg^−1)	1.56 ± 0.47^‡	1.95 ± 0.53

, , and as compared to the healthy subjects.
LTPA: leisure time physical activity, PWC: physical working capacity, HR: heart rate, TAC: total antioxidant capacity, FRAS: Ferric Reducing Ability of Serum, DPPH: 2.2-diphenyl-1-picryl-hydrazyl, and CHD: coronary heart disease.
