Potential Role of Amino Acid/Protein Nutrition and Exercise in Serum Albumin Redox State
Abstract: Albumin is the major protein in the serum of mammals. It is synthesized exclusively in the liver, before being secreted into the circulation. Similar to skeletal muscle protein, albumin synthesis is stimulated by dietary amino acids and proteins as well as exercise. Albumin has three isoforms based on the redox states of the free cysteine residue ...
Native whey protein with high levels of leucine results in similar post-exercise muscular anabolic responses as regular whey protein: a randomized controlled trial
Abstract
Background: Protein intake is essential to maximally stimulate muscle protein synthesis, and the amino acid leucine seems to possess a superior effect on muscle protein synthesis compared to other amino acids. Native whey has higher leucine content and thus a potentially ...
Mouth rinsing with a carbohydrate solution attenuates exercise-induced decline in executive function
Abstract
Background: A decline in executive function could have a negative influence on the control of actions in dynamic situations, such as sports activities. Mouth rinsing with a carbohydrate solution could serve as an effective treatment for preserving the executive function in exercise. The purpose of this study was to examine the effects ...
Low Vitamin D Levels Do Not Predict Hyperglycemia in Elderly Endurance Athletes (but in Controls)
Abstract
Background and AimRecent studies revealed a link between hypovitaminosis D3 and the risk for hyperglycemia.Further mechanistic and interventional investigations suggested a common reason for both conditions rather than a causal relationship. Exposure to sunlight is the most relevant source of vitamin D3 (25(OH)D), whereas adipose tissue ...
Fructose ingestion impairs expression of genes involved in skeletal muscle’s adaptive response to aerobic exercise
Abstract
Background: The inverse relationship between exercise capacity and its variation over time and both cardiovascular and all-cause mortality suggests the existence of an etiological nexus between cardiometabolic diseases and the molecular regulators of exercise capacity. Coordinated adaptive responses elicited by physical ...
Evaluation of the effects of two doses of alpha glycerylphosphorylcholine on physical and psychomotor performance
Abstract
Background: Recent studies have suggested that alpha glycerylphosphorylcholine (A-GPC) may be an effective ergogenic aid. The present study was designed to assess the efficacy of two doses of A-GPC in comparison to placebo and caffeine for increasing countermovement jump performance, isometric strength, and psychomotor ...
Effects of two pre-workout supplements on concentric and eccentric force production during lower body resistance exercise in males and females: a counterbalanced, double-blind, placebo-controlled trial
Abstract
Background: Pre-workout supplements purportedly enhance feelings of energy, reduce fatigue and improve exercise performance. The purpose of this study was to examine the performance effects of caffeinated and noncaffeinated multi-ingr...
Effects of Potassium Bicarbonate Supplements on Circulating microRNA Expression
Several studies suggest that neutralizing acid load in the diet with alkali had favorable effects on intermediate markers of musculoskeletal health. We examined whether alkali supplementation with potassium bicarbonate [(KHCO3); 81 mmol/d; n = 12] vs placebo (n = 12) for 84 days altered serum microRNAs, potential biomarkers associated with innumerable biological ...
