Abstract
Objectives: 1. Investigate whether clustered cardiometabolic risk score, cardiorespiratory fitness (CRF), sedentary time (ST) and body mass index Z-scores (BMI Z-scores), differed between participants that met and did not achieve ≥60mins of daily moderate to vigorous intensity physical activity (MPVA). 2. Compare clustered cardiometabolic risk score, BMI Z-score, ST and MVPA by CRF status.
Methods: 101 (n = 45 boys) 10-12year old participants took part in this cross-sectional study, conducted in Liverpool (Summer 2010) and Ulster (Spring 2011) UK. Assessments of: blood markers, stature, sitting stature, body mass, waist circumference, flow mediated dilation, and resting blood pressure were completed. CRF (VO2peak) was estimated using an individually calibrated treadmill protocol. Habitual MPVA and ST were assessed using an individually calibrated accelerometer protocol. Clustered cardiometabolic risk scores were calculated using blood markers and anthropometric measures. Participants were classified as active (≥60mins MVPA) or inactive and as fit or unfit. Multivariate analysis of covariance (MANCOVA) was used to investigate differences in cardiometabolic risk, BMI Z-score, CRF and ST by activity status. MANCOVA was also completed to assess differences in cardiometabolic risk, MVPA, ST, and BMI Z-score by fitness status.
Results: Inactive children exhibited significantly higher clustered cardiometabolic risk scores and ST, and lower CRF than active children. Unfit participants exhibited significantly higher clustered cardiometabolic risk scores, BMI Z-scores and ST and lower MVPA in comparison to fit participants.
Conclusions: This study highlights the importance of children achieving 60mins MVPA daily and provides further evidence surrounding the importance of CRF for health.
