Comparison of the effect of short-term consumption alone and a combination of L-arginine and L-citrulline supplements on aerobic and anaerobic capacity of young football players

The present study was conducted with the aim of comparing the effect of short-term use alone and a combination of L-arginine and L-citrulline supplements on the aerobic and anaerobic capacity of young soccer players.

n this semi-experimental study, which was conducted with a pre-test-post-test design, 60 young male soccer players with an age range of 15 to 18 years were selected as available and in 4 groups of 15 L-arginine supplement, L-citrulline supplement, combined of L-arginine, val-citrulline supplement and placebo. In the pre-test and post-test stages, the aerobic and anaerobic power of the subjects was measured using yo-yo tests and RAST test. The period of supplement consumption was for 7 days. The amount of L-arginine and L-citrulline supplements alone was 2.4 grams per day, and in the combined group, each of the supplements consumed 1.2 grams.

Short-term consumption (7 days) of L-arginine supplement, L-citrulline supplement and a combination of L-arginine and L-citrulline supplement on increasing aerobic power, peak anaerobic power, average anaerobic power, minimum anaerobic power and reducing the fatigue index of football players Young people have a significant effect (P>0.05). Other results indicate the greater effect of the combination of L-arginine and L-citrulline supplements compared to L-arginine and L-citrulline supplements alone in improving the aerobic and anaerobic capacity of young soccer players.

Based on the findings of the present study, it can be concluded that the combined use of L-arginine and L-citrulline supplements can be effective in increasing the aerobic and anaerobic capacity of young football players..
