Conclusion
EIMD, muscle damage, muscle fatigue, fatigue
Overall, neither AF nor RF affected the extent of EIMD of the hamstrings. However, the participants of the AF/ECC group showed comparable muscle damage even though less muscle work was needed to elicit these effects. Further, muscle fatigue seemed to affect ROM and muscle contractility after muscle damage. Future studies should aim to investigate the influence of different fatigue protocols in order to gain a better understanding on how residual fatigue might affect EIMD. Lastly, the present study further confirmed that the novel muscle measurement methods of TMG and SWE can detect changes in muscle characteristics after EIMD and might serve as useful tools for team physicians and other practitioners to assess muscle characteristics.
