The Effect of (EAA+B3) Supplementation on Selected Biochemical Variables and Recovery Indicators in Advanced Soccer Players

Abstract

The objective of the current investigation was to examine the effect of essential amino acids (EAA) and vitamin B3 supplementation on various biochemical parameters, recovery, and physical performance of advanced soccer players. An experimental research design was used with two equal groups. The participants were 24 advanced soccer players who were randomly assigned to the control and experimental groups. Each participant was given a placebo or a supplement of essential amino acids and vitamin B3 for 8 weeks.The participants were tested on the Running Anaerobic Sprint Test (RAST) and the Yo-Yo Intermittent Recovery Test Level 2 (Yo-Yo IR2), and the levels of lactate, creatine kinase (CK), and heart rate recovery were measured. The results showed significant differences between the two groups (p ≤ 0.05), which were in favor of the experimental group.The results of the current investigation showed that the supplementation of essential amino acids and vitamin B3 can improve recovery and physical performance of soccer players.
