Background: The numbers of people participating in road running are on the rise. However, road running (especially with downhill running) often accompanies muscle soreness, swelling, reduction of joint mobility and decrease in strength, known as exercise-induced muscle damage. Therefore, research has drawn attention to the emphasis on how to alleviate muscle soreness following downhill running (DHR). Among which, the benefits of using self-myofascial release combined with foam roller (SMR) still require further investigation. Purpose: To investigate the effects of SMR on muscle damage induced by DHR. Methods: Twenty-four healthy male participants who exercised regularly were divided into three groups: SMR 45 second group, SMR 30-second group and control group. All participants ran on a treadmill (-15% decline) for 30 minutes at the intensity of their pre-determined 70% V ‧O2max. The two SMR groups performed SMR immediately, after 24 and 48 hours following DHR, while the control group did not perform any SMR. Furthermore, creatine kinase (CK), maximal voluntary isometric contraction (MVIC), muscle soreness (SOR), range of motion (ROM) and circumstance (CIR) were measured before DHR, and 24-72 hours following DHR. Mixed two-way ANOVA were used to analyze the data. Results: The MVIC and ROM of the three groups dropped significantly during 24 to 72 hours after DHR, while SOR、CIR and CK increased significantly. However, after 72 hours of DHR, the MVIC of the SMR 45-second group was significantly higher than SMR 30-second group and control group. Even though SOR of the SMR 45-second group was significantly lower than the SMR 30-second group at all time points, there was no significant difference between the two groups and the control group. In addition, at 72 hours after DHR, the changes of CK from baseline of both SMR 45- and 30-second groups were significantly lower than the control group. There were no significant differences among the three groups in ROM and CIR at all time points. Conclusion: Performing SMR treatments (45 and 30 seconds) following DHR may aid in muscle recovery from damage, which is especially effective in the recovery of MVIC and CK, however, there may be no benefits for the recovery of ROM, SOR and CIR. Furthermore, the effect of performing SMR for 30 seconds may have less benefits when compared to SMR for 45 seconds.
