Body Composition and Weight Changes in a 15-week Marathon Training Program
Abstract: With the increasing rates of obesity worldwide, exercise and nutritional interventions have been at the forefront in attempts to produce positive health changes. The general public often views the effectiveness of an exercise program solely on changes in their weight. This research, demonstrates that weight loss may not occur without months of intervention and that weight loss may be a poor assessment to quantify immediate positive results. This study also gives evidence that the public needs a practical way to access body composition changes through intervention programs designed to lower body weight. Data was collected from a Marathon Training course offered at the University of Minnesota-TC through three consecutive years (2009-2011). Body composition and body weight were compared from a pre/post 15-wk structured marathon training plan. Results provided evidence that significant changes in body composition occurred for both male and females, however not body weight. This phenomenon was more prevalent in females, who actually gained weight, which is consistent with previous literature looking at the dichotomy of gender differences (Bjorntorp, 1980). This data further emphasizes the imperativeness of deemphasizing body weight as a solitary measurement of immediate changes in health gains through exercise. Download poster. [PDF]
