Background Sports nutrition is a constantly evolving field with hundreds of research papers
published annually. In the year 2017 alone, 2082 articles were published under the key …

With regular practice, resistance exercise can lead to gains in skeletal muscle mass by
means of hypertrophy. The process of skeletal muscle fiber hypertrophy comes about as a …

As a functional amino acid (AA), L-arginine (Arg) serves not only as a building block of
protein but also as an essential substrate for the synthesis of nitric oxide (NO), creatine …

The popularity of natural bodybuilding is increasing; however, evidence-based
recommendations for it are lacking. This paper reviewed the scientific literature relevant to …

Key points• Essential amino acids (EAAs) stimulate increased rates of myofibrillar protein
synthesis (MPS).• Leucine is a key regulator of MPS in rodents; however, its importance …

Nitric oxide related ergogenic aids such as arginine (Arg) have shown to impact positively
on sport performance through several physiological and metabolic mechanisms. However …

Nitric-oxide-stimulating dietary supplements are widely available and marketed to strength
athletes and weightlifters seeking to increase muscle performance and augment training …

The purpose of this study was to compare the effects of l-citrulline (Cit) and l-arginine (Arg)
supplementation on nitric oxide (NO) biomarkers, pulmonary O 2 uptake (V̇ o 2) kinetics …

Protein quality control (proteostasis) depends on constant protein degradation and
resynthesis, and is essential for proper homeostasis in systems from single cells to whole …

Provision of dietary amino acids increases skeletal muscle protein synthesis (MPS), an effect
that is enhanced by prior resistance exercise. As a fundamentally necessary process in the …
