Pure Juice Supplementation: Its Effect on Muscle Recovery and Sports Performance.

Strenuous exercise causes increased production of reactive oxygen species (ROS), creating an imbalance between ROS and antioxidants. The reduced antioxidant defence leads to defective elimination of ROS and consequently, delayed-onset muscle soreness (DOMS). DOMS due to exhaustive or prolonged exercise typically peaks between 24 h and 72 h after exercise results in soreness, inflammation, pain and decreased muscle function.

Branched-chain amino acid supplementation improves cycling performance in untrained cyclists.

Objectives: To investigate the effects of acute branched-chain amino acid (BCAA) supplementation on cycling performance and neuromuscular fatigue during a prolonged, self-paced cycling time-trial.

Design: Randomised double-blind counterbalanced crossover.

Methods: Eighteen recreationally active men (mean±SD; age: 24.

Characterizing the plasma metabolome during and following a maximal exercise cycling test.

Although complex in nature, a number of metabolites have been implicated in the onset of exercise-induced fatigue. The purpose of this study was to identify changes in the plasma metabolome and specifically, to identify candidate metabolites associated with the onset of fatigue during prolonged cycling. Eighteen healthy and recreationally active men (mean ± SD; age: 24.
