Abstract
Introduction: Because hamstring muscle strain is the most common muscle injury in football, and limited studies have been conducted on the effect of massage with eccentric exercises on the prevention of this type of injury so far, and the results of such research can help to choose an effective technique to prevent injuries to this muscle. Therefore, this study aimed to investigate the immediate and delayed effects of eccentric exercise with and without massage on some risk factors for hamstring strain in male soccer players.
Research Methodology: The subjects who participated in this study included 24 male football players from 2 clubs in Tehran province. Players were randomly divided into 2 groups (intervention 1 and intervention 2). In the pretest stage, the strength of the hamstring muscles was measured by a biodex isokinetic dynamometer. Intervention group 1 performed Nordic exercise and massage protocol on them and intervention group 2 performed only Nordic exercise. Finally, immediately after the end of the exercise and the massage protocol, the subjects were retested, and then one hour after the end of the posttest, the subjects were post-hacked.
Results: The results of this study showed that The ratio of H: Q strength was significant at a speed of 180 ° / s in the group without massage at the posttest-post hoc level, and also the ratio of H: Q strength was significant at a speed of 300 ° / s in the group without massage at the pretest-posttest and pretest-post hoc levels. On the other hand, the concentric hamstring strength at a speed of 60, 180, and 300 ° / s was not significant in any of the groups, speeds, and levels. Finally, the eccentric hamstring strength was measured at a speed of 60, 180, and 300 ° / s. eccentric hamstring strength at a speed of 60 ° / s and 180 ° / s in the group with massage at the pretest-posttest and pretest-post hoc level, and a speed of 180 ° / s in the group without massage at the pretest-post hoc and posttest–post hoc levels and at a speed of 300 ° / s at the pretest-posttest level was significant (P<0.05).
Conclusion: From the findings of this study can be concluded that no significant difference was observed between two groups of eccentric exercises with and without massage.
