Association between Injury and Reported Pain and Lower Extremity Tissue Mass Ratios in Varsity Athletes

The purpose of this study was to determine (a) if the tissue mass ratios (TMRs) of the lower extremities of athletes differ as a function of Sport, Sex and Time of Season; (b) if an association between TMRs and lower extremity injury exist, and (c) whether there is an association between TMRs and self-reported pain. Forty-two varsity athletes attended data collection sessions at the beginning and end of their competitive seasons. Estimates of TMRs and present pain intensity were obtained. Females experienced an increase in the LM (Lean Mass):FM (Fat Mass) ratio and males experienced a decrease in the LM:BMC (Bone Mineral Content) ratio as the season progressed. TMRs and injury were not significantly associated, however as the season progressed, changes seen in TMRs were associated with more athletes reporting pain.
