Abstract

The aim of this study was to examine the impact of a 33-week program, which included two weekly intensive running sessions, on aerobic capacity, BMI, waist circumference and body composition in overweight and obese, inactive adults. An additional aim was to examine the additional impact of lifestyle modification education. Twenty-four participants in the Training Group (exercise only) and 27 in the Nutritional Guidance and Training Group (exercise + nutritional guidance) completed the study. Anthropometric measurements (BMI, waist circumference, visceral fat, muscle mass and fat percentage) and 3000 m running time were measured at start, after 15 weeks (BMI, waist circumference and 3000 m running time) and after 33 weeks of intervention. Significant reductions in BMI, waist circumference, fat percentage and 3000 m running time were found for both groups. A small, but insignificant, increase was found for muscle mass in both groups and visceral fat in the training group. A significant interaction effect for visceral fat was also found. Both groups improved their running time and anthropometric measurements. No significant differences were found between the groups.
