Open AccessEssential amino acid supplements ingestion has a positive effect on executive function after moderate-intensity aerobic exercise
Aerobic exercise acutely improves cognitive function (e.g., executive function (EF); memory recognition (MR)) and increases circulating brain-derived neurotrophic factor (BDNF). In addition, branched-chain ami...

Open AccessThe lactate response to a second bout of exercise is not reduced in a concurrent lower-limb exercise program
We aimed to evaluate the blood lactate level in response to two bouts of exercise. First, we hypothesized that blood lactate elevation in response to moderate-intensity aerobic exercise (MIAE) would be lower a...
