A 10-Month Physical Activity Intervention Improves Body Composition in Young Black Boys

Table 3

Relationships between Body Composition, CV Fitness and Physical Activity levels at Baseline and Follow-up. (Pearson correlation coefficients).

		Body Composition
	Time	BF	BMI	FM	FFM	MVPA
		(%)	(kg/m^2)	(kg)	(kg)	(hrs/day)
VO2-170 (ml/kg/min)	BL	−0.64	−0.63	0.64	−0.48	0.01
	FU	−0.76	−0.67	0.71	−0.32	0.22
MVPA(hrs/day)	BL	0.20	0.22	0.24	0.22	—
	FU	−0.18	−0.08	-0.1	0.06	—

VO₂-170 = the VO₂ at a heart rate of 170 bpm during the graded treadmill test; BF = body fat; BMI = body mass index; FM = fat mass; FFM = fat free mass; MVPA = moderate-to-vigorous physical activity; BL = baseline; FU = follow-up; Bold italic font indicates a significant relationship (p<.05).
