Huang WC, et al. - The beneficial effect of whey protein was contemplated, on the physiological adaptions and exercise performance. It was deduced that whey protein could be advantageous by improving the physiological adaptation, alongside the resistance training. It could serve as a potential nutrient supplement with multiple benefits for amateur runners.

Methods

• The eligible candidates comprised of 12 elite male track runners.
• They were randomly assigned to whey and maltodextrin groups for 5 weeks' supplementation.
• During this period, three time points (pre-, post-, and end-test) examined the associated biochemical parameters, body composition, and performance.
• In addition, the post-test was set 1 day after a marathon for injury status evaluation and the end-test was analyzed after 1-week recovery from endurance test.

Results

• The whey group illustrated considerably lower aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and creatine kinase indicators after the marathon (post-test), as well as at the end-test (p<0.016).
• A prominent elevation was disclosed in the endurance performance in twelve-minute walk/run (p<0.012).
• This could be attributed to an increase in the muscle mass and amelioration of exercise injuries.
