Conclusion Overall , our findings do not support the presence of a secondary loss of strength following an acute muscle injury , and strongly suggest that strength , on average , recovers steadily over the first 3 days post-injury
Background An immediate loss of strength follows virtually all types of muscle injury but there is debate whether the initial strength loss is maximal or if a secondary loss of strength occurs during the first 3 days post-injury .
Objective The objective of this analysis was to conduct a systematic review and meta- analysis of the research literature to determine if a secondary loss of strength occurs after an injurious initiating event .
The Effects of Repeated Maximal Voluntary Isokinetic Eccentric Exercise on Recovery from Muscle Damage
Abstract This study investigated whether performing repeated bouts of maximal voluntary isokinetic eccentric exercise ( MAX1 ) on 3 ( MAX3 ) and 6 days ( MAX6 ) after the initial bout would produce significant changes in the indirect markers of muscle damage and total work . A secondary purpose was to determine whether participants ' psychological maximal effort was equivalent to the physiological maximal effort during muscle soreness . Male university students were assigned r and omly to a control group ( n = 12 ) and a group that repeated the exercise ( EX ; n = 12 ) . The MAX1 was 3 × 10 repetitions of the nondominant elbow flexors on the Cybex 6000 system at a speed of 60 deg/s . The EX group performed the same exercise 3 days and 6 days after MAX1 . The range of motion and maximal isometric force ( MIF ) , muscle soreness index , plasma creatine kinase , and glutamic-oxaloacetate transaminase activities were measured before and every 24 hr for 9 days after MAX1 for both groups . MIF was also assessed once before and immediately after each MAX for the EX group . There were no significant changes ( p > .05 ) between the groups for all criterion measures , except for total amount of work ( p < .05 ) . It is concluded that strenuous voluntary isokinetic eccentric exercise performed with damaged muscles does not appear to exacerbate damage or influence the recovery process . Although individuals could perform repeated MAXs , the total work performed was significantly reduced . This has practical implication s in strength training for coaches and athletes during muscle damage
