Local Vibration Reduces Muscle Damage after Prolonged Exercise in Men

Area of Science:

• Sports Medicine
• Exercise Physiology
• Muscle Recovery

Background:

• Prolonged exercise can cause muscle damage, leading to soreness, swelling, and reduced strength.
• Whole-body vibration (WBV) has shown potential in improving exercise recovery by modulating stress hormones and muscle damage markers.
• The efficacy of localized vibration treatment post-exercise on muscle damage indicators requires further investigation.

Purpose of the Study:

• To investigate the effect of local vibration treatment applied after prolonged exercise on muscle fiber damage markers.
• To compare the levels of myoglobin (Mb), creatine kinase (CK), and lactate dehydrogenase (LDH) following vibration therapy versus placebo.

Main Methods:

• Twelve untrained men performed a 180-minute exercise bout at 50% VO2peak.
• Participants received a 60-minute local vibration treatment or placebo therapy post-exercise.
• Blood samples were analyzed for Mb, CK, and LDH levels before, immediately after, and 24 hours post-recovery.

Main Results:

• Immediately after the recovery procedure, the vibration group showed significantly lower Mb, CK, and LDH levels compared to baseline.
• Twenty-four hours post-exercise, the vibration group continued to exhibit significantly lower concentrations of Mb, CK, and LDH.
• Local vibration therapy resulted in significantly reduced muscle damage markers compared to the placebo control group.

Conclusions:

• Topical vibration applied after prolonged physical exertion enhances post-workout recovery.
• Vibration treatment effectively reduces markers of muscle fiber damage, including myoglobin, creatine kinase, and lactate dehydrogenase.
• Local vibration therapy presents a promising strategy for improving recovery from strenuous exercise.
