Abstract
INTRODUCTION: There is limited information on the general presentation of limb-specific body composition, in collegiate athletes. Additionally anthropometric measurements, from a 3-dimensional body scanner (3DBS) have seen limited use in an athletic population. The purpose of this study is to investigate segmental lean mass (sLM) and anthropometric measurements (AM) in the extremities of Division 1 athletes, and how these measurements change over a competitive season. METHODS: Dual-energy x-ray absorptiometry (DEXA) and 3DBS assessments were conducted on 188 athletes, 108 males (Age(years): 19.98 ± 1.47; Height(cm): 186.07 ± 7.43; Weight(kg): 102.00 ± 24.69) and 80 females (Age(years): 19.60 ± 1.55; Height(cm): 166.51 ± 8.22; Weight(kg): 64.48 ± 8.22) . SLM assessed with DEXA as well as limb surface area, limb volume, and circumferential measurements from the calf, thigh, forearm, and biceps were assessed with the 3DBS. Paired samples t-tests were used to assess changes in dependent variables over a season, one-way ANOVAs where used to assess inter-sport differences, 2-way mixed measures ANOVAs were used to assess intra-sport differences among male and female cross-country athletes, and Pearson’s correlation coefficients were used to compare dependent variables from the DEXA to dependent variables from the 3DBS. Statistical significance was set a priori at α=0.05. RESULTS: Overall the whole cohort saw an increase in all sLM variables (p < 0.001 – 0.012), and saw changes in all AM, besides right calf circumference, right arm surface area, and right arm volume. Inter-sport analysis showed a difference in all dependent variables between sports in the male cohort (p < 0.001) and in the female cohort (p < 0.001 – 0.012). Correlations between raw sLM and AM values were all strong to very strong (r = 0.764 – 0.951; p < 0.001). CONCLUSION: These results show that athletes from this cohort generally experienced increases in sLM and AM, adaptations to these measurements were different between sports, and strong correlations show there could be a use for the 3DBS in athletics. More research is needed to validate this study’s findings, since there are few studies which assessed limb specific measurements, and the first study which assessed anthropometric measurements in populations assessed.
