In previous studies, we reported that the strength training using Multi Hip Joint Board （MHJB） could increase the cross-sectional area of the psoas major muscle （PMCSA） and improve sprint performance. However, only collegiate male sprinters were tested in these studies, and the effects of MHJB training have not been examined with non-sprinters. Therefore, we aimed to investigate the effects of MHJB training on PMCSA and running performance of a collegiate male middle-distance runner. The present study was conducted during a winter preparation period. The MHJB training was conducted three times per week for six weeks in addition to his normal daily workout. PM CSA and running performance were measured before and after the MHJB training. PM CSA was measured by a magnetic resonance imaging, and the running performance was defined as the certified 800-meter running record. The subject showed improvements in PM CSA and 800-meter running performance after six weeks of training. The MHJB training could be used as one of the training methods to improve running performance of middle-distance runners.
