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 .
Whole-body vibration and the prevention and treatment of delayed-onset muscle soreness.
CONTEXT Numerous recovery strategies have been used in an attempt to minimize the symptoms of  delayed-onset muscle soreness ( DOMS ) .  Whole-body vibration ( WBV ) has been suggested as a viable warm-up for athletes . However , scientific evidence to support the protective effects of WBV training ( WBVT ) on muscle damage is lacking . OBJECTIVE To investigate the acute effect of WBVT applied before eccentric exercise in the prevention of DOMS . DESIGN R and omized controlled trial . SETTING University laboratory . PATIENTS OR OTHER PARTICIPANTS A total of 32 healthy , untrained volunteers were r and omly assigned to either the WBVT ( n = 15 ) or control ( n = 17 ) group . INTERVENTION(S ) Volunteers performed 6 sets of 10 maximal isokinetic ( 60 ° /s ) eccentric contractions of the dominant-limb knee extensors on a dynamometer . In the WBVT group , the training was applied using a vibratory platform ( 35 Hz , 5 mm peak to peak ) with 100 ° of knee flexion for 60 seconds before eccentric exercise . No vibration was applied in the control group . MAIN OUTCOME MEASURE(S ) Muscle soreness , thigh circumference , and pressure pain threshold were recorded at baseline and at 1 , 2 , 3 , 4 , 7 , and 14 days postexercise . Maximal voluntary isometric and isokinetic knee extensor strength were assessed at baseline , immediately after exercise , and at 1 , 2 , 7 , and 14 days postexercise . Serum creatine kinase was measured at baseline and at 1 , 2 , and 7 days postexercise . RESULTS The WBVT group showed a reduction in DOMS symptoms in the form of less maximal isometric and isokinetic voluntary strength loss , lower creatine kinase levels , and less pressure pain threshold and muscle soreness ( P < .05 ) compared with the control group . However , no effect on thigh circumference was evident ( P < .05 ) . CONCLUSIONS Administered before eccentric exercise , WBVT may reduce DOMS via muscle function improvement . Further investigation should be undertaken to ascertain the effectiveness of WBVT in attenuating DOMS in athletes
