Abstract

Purpose: One purpose of this study was to assess changes in body composition throughout an off-season of two consecutive seasons, by measuring changes in body mass, fat mass, and lean body mass before and after a 16-week off-season training program. The second purpose of this study was to assess changes in macronutrient composition. Methods: 46 male college football players participated in this study during Season-1. 29 male college football players participated in this study during Season-2. A pre-test, post-test study design tracked body composition from post-season through offseason. Results: Significant changes in lean mass were not observed during the offseason training program. Surprisingly, the change in muscle area at the 66% site of the lower leg significantly increased in area. Total body mass and body fat did not change during the off-seasons. Conclusion: No significant changes in total body lean mass and leg lean mass were observed during a 16-week offseason training program. Because of the low number of participants, comparisons across groups, linemen and skill players, and upper- and lower-classmen were not made. Surprisingly, the change in muscle area at the 66% site of the lower leg significantly increased in area, an indication that the gastrocnemius and soleus muscle increased in mass. A significant difference in macronutrient composition was only found in fat consumption.
