Supplementation with amino acids for muscle recovery can be effective onoxidative stress and muscle damage. This study aims to compare the effects of pea protein and wheyprotein supplements on muscle damage, delayed onset muscle soreness (DOMS), and functionalperformance after high-intensity functional training (HIFT) bout in untrained overweight young men.

In this randomized, double-blind, placebo-controlled clinical trial, 30 untrainedoverweight young men were selected by a purposive sampling method and divided randomly into threedifferent groups of pea protein (n=10), Whey Protein (n=10), and placebo (n=10). Variables relatedto muscle damage and DOMS were measured 24 hours after HIFT. Repeated measures ANOVA andBonferroni post hoc test were used to compare the differences between groups.

There was a significant difference between the two evaluation stages. There was a significantdifference between the Whey protein and pea protein groups compared to the placebo group (P<0.05),but no significant difference was found between the Whey protein and pea protein groups (P<0.05).

The use of Whey protein, compared to pea protein, can reduce muscle damage and DOMSfollowing HIFT

Anxiety has been identified as the most common mental health disorder and 30% of psychological disorders in societies are due to early-life stress. The aim of this study was to investigate the effect of mandatory exercise on anxiety and bowel oxidative stress in male rats following the maternal separation stress

In this experimental study, the maternal separation stress on baby rats was applied, so that, babies were separated from their mother during postnatal day (PND) 2 to 14, for 180 minutes a day. At PND 28, rats were randomly divided into five groups including control group, maternal separation stress group, mandatory treadmill exercise, maternal separation with treadmill, and maternal separation with the intake of fluoxetine. At PND 60, after finishing the program, in addition to behavioral tests, biochemical and tissue biopsy, for measuring the oxidative stress biomarkers (ROS level), were applied.

Our investigation revealed that only the intake of fluoxetine during adolescence can significantly make change on the anxiety-like behaviors, ROS level, and the level of mitochondrial glutathione; however, the observed difference among the other groups was not significant.

This study suggested that maternal separation stress was able to appear anxiety-like behaviors. In addition, a significantly change on the bowel oxidative stress was observed. It seems the effect of exercise on stress can be affected by intensity and duration of exercise, the rest time after exercise, and also the stress level before the exercise
