In this study, we used evaluation of physique, body composition, and a hierarchical fitness degree balance system to examine changes between the time of enrollment and graduation for newly-recruited male students at a firefighting academy. Results showed a decrease in the body fat percentage of the students. However, we clarified for the first time that the number of students in the “average, standard development of fat” group decreased and the number of students in the “lean, underdevelopment of fat” group increased. Based on these results, we found that reduction of body fat is effective for the “obese” group and the “excessive development of fat” group. However, for the “average” group and the “lean” group, we concluded that the prevention of excessive loss of body fat and the acquisition of muscle mass were the important themes for further improvement of productivity.
