Therefore, this study aimed to clarify how a muscle fatigue condition affects the success of hamstring injury prevention programs in sprinters. The study subjects were 613 collegiate male sprinters. They employed submaximal\/maximal running for a large number of runs and supramaximal running for a small number of runs in daily training. The hamstring injury prevention program had become the most effective strategy in the past 24 seasons of track and field for preventing hamstring injuries. The number of sprinters who experienced hamstring injuries in three periods over the 24 seasons was recorded. The incidents of hamstring injuries during supramaximal running per athlete-seasons were 137.9, 60.6, and 6.7 for Periods I, II, and III, respectively, showing a significant decline (p &lt; 0.01). Furthermore, the incidents of hamstring injuries during submaximal and maximal running per season showed no significant change. The results of this study indicate that by inducing muscle fatigue, a small number of runs makes hamstring injury prevention programs effective.<\/jats:p>","DOI":"10.3390\/ijerph19159375","type":"journal-article","created":{"date-parts":[[2022,7,31]],"date-time":"2022-07-31T23:37:29Z","timestamp":1659310649000},"page":"9375","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of Various Numbers of Runs on the Success of Hamstring Injury Prevention Program in Sprinters"],"prefix":"10.3390","volume":"19","author":[{"given":"Yusaku","family":"Sugiura","sequence":"first","affiliation":[{"name":"Sport Science, Meikai University, Urayasu 279-8550, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiko","family":"Sakuma","sequence":"additional","affiliation":[{"name":"Graduate School of Health and Sports Science, Juntendo University, Inzai 270-1695, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6930-4403","authenticated-orcid":false,"given":"Shimpei","family":"Fujita","sequence":"additional","affiliation":[{"name":"College of Health and Welfare, J.F.
