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 .
Sensory level electrical muscle stimulation: effect on markers of muscle injury
Background : Monophasic high voltage stimulation ( MHVS ) is widely prescribed for the treatment of inflammation associated with muscle injury . However , limited scientific evidence exists to support its purported benefits in humans . Objective : To examine the efficacy of early initiation of MHVS treatment after muscle injury . Methods : In a r and omised , cross over design , 14 men performed repetitive eccentric contractions of the elbow flexor muscles followed by either MHVS or control treatment . MHVS treatments were applied five minutes and 3 , 6 , 24 , 48 , 72 , 96 , and 120 hours after eccentric contractions . Results : MHVS result ed in a significant reduction ( p<0.05 ) in delayed onset muscle soreness 24 hours after eccentric exercise compared with controls . Elbow extension was significantly increased immediately after administration of MHVS compared with controls . No significant differences were observed between MHVS treatment and controls for maximal isometric strength , flexed arm angle , or arm volume . Conclusions : Early and frequent application of MHVS may provide transient relief from delayed onset muscle soreness and short term improvements in range of motion after injurious exercise . However , MHVS treatment may not enhance recovery after muscle injury because of lack of improvements in strength and active range of motion
