Abstract

Low cardiorespiratory fitness (CRF) is a risk
factor for cardiovascular disease (CVD) but the association
of muscular fitness phenotypes (strength, endurance
and power) on CVD risk in youth has not been examined.
We examined the cross-sectional association
between muscular fitness phenotypes with individual
and clustered CVD risk factors and determined if any
potential associations are independent of CRF. Participants
were 1,642 youth aged 9, 12, and 15 years from the
Australian Schools Health and Fitness Survey that had
muscular strength (dynamometer), power (standing
long-jump), and endurance (push-ups) as well as CRF
(1.6 km run-time) measured. Outcomes included established
risk factors (body mass index, waist circumference,
blood lipids and blood pressure) and a clustered
CVD risk-score. Muscular strength, endurance, and
power were inversely associated with clustered CVD
risk (all P < 0.05). After adjustment for body mass
index, the association remained for muscular endurance
and power (all P · 0.001), but not strength. Muscular
power was inversely related to prevalence of clustered
CVD risk (¸80th percentile) within low (Ptrend < 0.001),
moderate (Ptrend < 0.001), and high (Ptrend = 0.001) CRF
categories. Among youth, low muscular fitness levels as
well as low CRF should be avoided for primary CVD
prevention.
