[Purpose] Bone union in Jones fracture is difficult to attain. Thus, we aimed to clarify the longitudinal changes in body composition and circumference of the lower extremities from injury to return to training. [Participants and Methods] The subject was a 20-year-old male futsal player. He fell during a practice game of futsal and had a fracture injury. He underwent physical therapy exercise after a 7-week non-weight bearing period (NWBP) and returned to training. [Results] His body weight and whole muscle mass decreased during the NWBP after the operation. Although the muscle proportion of the right lower extremity declined and that of the other side showed an opposite trend, no left-right difference was found in the circumference of the lower extremities. [Conclusion] The results of this study show that changes in the circumferences of the lower extremities are less likely to occur during NWBP. However, with regard to body composition, a decreased muscle ratio was observed in this study.
