A period of intense or prolonged muscle activity can cause a decline in performance, which can range from muscle weakness to muscle damage and soreness. Muscle fatigue can be largely reversible in minutes or hours. It is generally viewed to be the result of insufficient energy and a lack of availability of key metabolites that enable contracting muscles to meet increased energy demand. However, muscle recovery can fail to take effect quickly, and this can be associated with structural changes and damage within the muscle, inducing a cascade of events leading to immediate or delayed soreness.
In previous research, Sepifit TM Protect, a combination of natural red wine polyphenols, zinc and vitamin E, showed in vitro efficacy with respect to lactate, interleukin-6 and creatine kinase, which are markers of muscle damage and fatigue. We have therefore conducted a pilot clinical study to evaluate the effects of this active complex in healthy men undertaking regular and stable physical activity and who were subjected to a pain induction protocol. The results showed that the consumption of 135 mg of the complex per day for 12 days was effective in reducing creatine kinase release and maintaining muscular power capacity after the pain induction protocol. It also induced a better perception of performance, physical condition and muscle soreness. SEPIFIT TM Protect can thus be considered an interesting complex to contribute to muscle recovery during physical exertion.
