BACKGROUND: Total and regional body composition measures are directly related to performance and injury prevention. Multifrequency bioelectrical impedance analysis (MF-BIA) is a feasible method to track season long body composition changes. The purpose of this study was to examine the effect of an 8-week summer strength and conditioning program on body composition in National Collegiate Athletic Association (NCAA) Division I basketball players. METHODS: Body composition of 14 NCAA Division I basketball players (Age=20.4±1.3 yrs, Height=193.3±7.1cm, Weight=90.5±9.6 kg, Percent Body Fat =10.0±3.6%) was measured using MF-BIA at the start of summer training (May 2021) and again after concluding an 8-week strength and conditioning program (July 2021). Total body fat mass (FM), fat free mass (FFM) and regional (trunk, arms, legs) FM and FFM outcomes were evaluated. Paired sample t-tests were used to evaluate the pre- and post-training FM and FFM outcomes. RESULTS: Total body FM decreased significantly from pre- to post-training [Mean Difference (Pre-Post)±Standard Error: 0.89±0.26 kg, p=0.005). Trunk FM (-0.49±0.17 kg, p=0.014), left leg FM (-0.20±0.04 kg, p<0.001), and right leg FM (-0.17±0.03 kg, p<0.001) decreased significantly from pre- to post-training. Total FFM (2.46±0.50 kg, p<0.001) increased significantly from pre- to post- training. Trunk FFM (1.37±0.21 kg, p<0.001), left arm FFM (0.25±0.04 kg, p<0.001), and right arm FFM (0.27±0.05 kg, p<0.001) increased significantly, with no significant change in leg FFM from pre- to post-training. CONCLUSION: The overall increase in total body FFM and decrease in total body FM demonstrates the importance of off-season strength and fitness development. Future evaluations of the effect of number of sessions attended, the volume and intensity of exercise, and years of experience on the efficacy of an off-season training program may be warranted.
