Combination Supplement May Help Increase Muscle Power Capacity
Workouts cause muscle fatigue and micro-trauma to the muscle tissue and this needs time to repair. Generally, the harder the workout, the longer the recovery period required. According to a new study, supplementing with red wine polyphenols, zinc, and vitamin E may help maintain muscle power capacity and improve muscle recovery.
Thirty healthy men between the ages of 18 and 40 participated in the study. All exercised between 1.5 and 4.5 hours per week prior to the study. They took a supplement containing 135 mg of red wine polyphenols, zinc, and vitamin E or a placebo daily for 12 weeks. They filled out the International Physical Activity Questionnaire-Short Form at baseline and at the end of the study.
Muscular power capacity was evaluated via a functional capacity test at baseline and at the end of the study after completing a pain induction protocol. The pain induction protocol was used to mimic physical exertion and to induce muscular pain. Blood samples were taken at baseline and after the pain induction protocol to measure levels of creatine kinase and lactate. Levels of creatine kinase increase when muscle damage occurs. Lactate is a marker of physical fatigue.
Following the pain induction protocol, the muscular power capacity score for participants in the supplement group decreased by 1.1 cm. The decrease for participants in the placebo group was 5.2% higher, at 2.3 cm. Sixty-seven percent of participants in the supplement group felt less muscle soreness compared to 43% in the placebo group.
In addition, levels of creatine kinase following the pain induction protocol were 70% higher in the placebo group than in the supplement group. No statistical difference was seen in levels of lactate.
The study was conducted by researchers from Seppic. It was published on May 1, 2020 in the journal Nutrafoods.
