Table 3. Standardised coefficients (β) between HRR and body composition measures using multiple linear regression after controlling for age, pulse rate, blood pressure and smoking status.

Body Composition	Boys				Girls
	HRR 1 min		HRR 2 min		HRR 1 min		HRR 2 min
	β	p	Β	p	β	p	β	p
BMI z-score	0.153	NS	0.132	NS	-0.108	NS	-0.008	NS
Body Fat (%)	-0.102	NS	-0.029	NS	-0.233	NS	-0.325	0.008
