Effect of Vibration Treatment on Symptoms Associated with Eccentric Exercise-Induced Muscle Damage.
We tested the hypothesis that the magnitude of changes in indirect muscle damage markers would be greater after maximal elbow flexor eccentric exercise in the supinated (shorter biceps brachii) than neutral wrist (longer) position, and the difference in the magnitude would be associated with greater elongation over contractions for the supinated than neutral position, rather than the initial muscle length. Ten untrained men (21‐39 y) performed two bouts of 10 sets of 6 maximal isokinetic eccentric contractions of the elbow flexors in the supinated position for one arm and neutral position for the other arm separated by 2 weeks in a randomized order. Biceps brachii myotendinous junction (MTJ) movements during eccentric contractions were recorded by B‐mode ultrasonography, and the displacement from the start to end of each contraction was quantified.
Peak torque (supinated: 367.8±112.5 Nm, neutral: 381.5±120.4 Nm) and total work (1816±539 J, 1865±673 J) produced during eccentric contractions were similar between conditions. The average MTJ displacement increased (P<0.05) from the 1st set (8.0±2.0 mm) to 10th set (15.8±1.9 mm) for the supinated condition, but no such increase was found in the neutral condition (1st set: 5.1±1.0 mm, 10th set: 5.0±0.8 mm). Changes in indirect muscle damage markers (maximal voluntary isometric contraction torque, range of motion, serum creatine kinase activity and muscle soreness) after exercise were greater (P<0.05) for the supinated than neutral condition. These results suggest that the greater muscle damage marker changes for the supinated than neutral wrist position was associated with the greater muscle lengthening (strain).
Objective:
Delayed-onset muscle soreness (DOMS) is a symptom of exercise-induced muscle injury that is commonly encountered in athletes and fitness enthusiasts. Vibration is being increasingly used to prevent or treat DOMS. We therefore carried out a meta-analysis to evaluate the effectiveness of vibration in patients with DOMS.
Method:
We searched nine databases for randomized controlled trials of vibration in DOMS, from the earliest date available to 30 May 2018. Visual analogue scale (VAS) and creatine kinase (CK) levels were set as outcome measures.
Results:
The review included 10 identified studies with 258 participants. The meta-analysis indicated that vibration significantly improved the VAS at 24, 48, and 72 hours after exercise, and significantly improved CK levels at 24 and 48 hours, but not at 72 hours.
Conclusion:
Vibration is a beneficial and useful form of physiotherapy for alleviating DOMS. However, further studies are needed to clarify the role and mechanism of vibration in DOMS.
