Abstract

The aim of this thesis was to investigate the impacts of physical activity (PA), cardiorespiratory fitness (CRF), body composition and lifestyle education on cardiometabolic (CM) risk in 10-11 year old children. This broad aim was approached using three studies. Studies 1 and 2 were cross sectional observational studies, and study 3 was a clustered randomised control trial, with intervention effects assessed at post intervention and again at 8 to 10 weeks after the intervention. Initially, in the first cross sectional study (Chapter 4) the relationships between non- invasive (LV Mass, E/A, E'/A', E/E', trunk fat mass, whole body fat mass) and invasive CM risk markers (CRP, HOMA-IR, adiponectin, TC: HDL-C), and between all risk markers and CRF (V02 peak), time spent sedentary, moderate to vigorous intensity PA (MVPA) and vigorous PA (VPA) were investigated in 10-11 year old children (n=62). The key findings were significant but generally weak relationships present between some of the non- invasive and invasive markers of CM risk and risk markers also had significant correlations with measures of CRF and PA. CRP was significantly positively correlated with whole body fat in boys (rho=0.486, p<0.05) and girls (rho = 0.485 , p
