Does an 8-month physical training program improve left ventricular structure and function in obese adolescents?
An 8-month physical training program successfully improves cardiovascular fitness and reduces adiposity in obese adolescents, but does not significantly alter left ventricular structure or function.
Mitchell et al. (2002) conducted an RCT in Obesity (n=81). Physical training (PT) plus lifestyle education (LSE) vs. Lifestyle education (LSE) alone was evaluated on Changes in left ventricular mass index (LVM/Ht(2.7)), midwall fractional shortening (MFS), and relative wall thickness (RWT). An 8-month physical training program improved cardiovascular fitness and reduced adiposity but did not significantly improve left ventricular structure and function in obese adolescents.
