Participants performed unilateral flexibility training (experimental leg; EL) on an isokinetic dynamometer, while the contralateral limb acted as control (CL). Hip range of motion (ROM), passive, isometric, and concentric torques, active optimum angle, and biceps femoris and semitendinosus muscle thickness and ultrasound echo intensity were assessed both before and after the training. Additionally, muscle soreness was assessed before and after an acute eccentric exercise bout in both legs (EL and CL) at post\u2010training only. Hip ROM increased (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001) only in EL after the training (EL\u00a0=\u00a010.6\u00b0 vs CL\u00a0=\u00a01.6\u00b0), but no changes (<jats:italic>P<\/jats:italic>\u00a0&gt;\u00a0.05) in other criterion measurements were observed. After a bout of eccentric exercise at the end of the program, isometric and dynamic peak torques and muscle soreness ratings were significantly altered at all time points equally in EL and CL. Also, active optimum angle was reduced immediately, 48 and 72\u00a0hours post\u2010exercise, and hip ROM was reduced at 48 and 72\u00a0hours equally in EL and CL. Finally, biceps femoris muscle thickness was significantly increased at all time points, and semitendinosus thickness and echo intensity significantly increased at 72\u00a0hours, with no significant differences between legs. The stretching training protocol significantly increased hip ROM; however, it did not induce a protective effect on EIMD in men with tight hamstrings.<\/jats:p>","DOI":"10.1111\/sms.13068","type":"journal-article","created":{"date-parts":[[2018,2,3]],"date-time":"2018-02-03T12:06:38Z","timestamp":1517659598000},"page":"1671-1680","source":"Crossref","is-referenced-by-count":17,"title":["The effects of flexibility training on exercise\u2010induced muscle damage in young men with limited hamstrings flexibility"],"prefix":"10.1111","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2013-1652","authenticated-orcid":false,"given":"C.
