Myofibre damage in human skeletal muscle: effects of electrical stimulation versus voluntary contraction

Key Points

• Myofibre damage is significantly different between electrical stimulation and voluntary contraction, impacting muscle recovery.
• In evaluations, electrical stimulation has been associated with greater muscle damage compared to voluntary contraction in normalized force outputs.
• This analysis highlights the effects of electrical stimulation on muscle integrity and recovery based on contraction type in human skeletal muscle.
• Understanding these differences may inform rehabilitation strategies following injuries or surgeries to optimize muscle repair.
