Summary
Ascorbic acid (vitamin C) supplementation may reduce delayed-onset muscle soreness after strenuous calf exercise. This study found a significant difference in pain reduction between ascorbic acid and placebo groups.
Area of Science:
- Exercise Physiology
- Nutritional Science
- Sports Medicine
Background:
- Delayed-onset muscle soreness (DOMS) is a common issue following strenuous physical activity.
- The posterior calf muscles are frequently affected by DOMS after intense exercise.
- The potential role of antioxidants, such as ascorbic acid, in mitigating muscle soreness is of interest.
Purpose of the Study:
- To investigate the efficacy of ascorbic acid in reducing delayed-onset muscle soreness.
- To compare the effects of ascorbic acid versus a placebo on calf muscle pain.
Main Methods:
- A double-blind, randomized, crossover study design was employed.
- Participants received either ascorbic acid or a lactose placebo.
- Pain levels were assessed using visual analog scales and pain-challenging methods.
Main Results:
- A significant difference in soreness was observed between the ascorbic acid and placebo groups at peak soreness.
- Typical soreness abatement scores ranged from 25-44% in the treatment group.
- The study identified limitations including a small sample size (n=19) and lack of an untreated control group.
Conclusions:
- Ascorbic acid may offer a beneficial effect in alleviating delayed-onset muscle soreness.
- Further research with larger sample sizes and varied exercise protocols is warranted to confirm these findings.
