    The short-term effect of high versus moderate protein intake on recovery after strength training in resistance-trained individuals Abstract Background: Dietary protein intakes up to 2.9 g.kg−1 .d−1 and protein consumption before and after resistance training may enhance recovery, resulting in hypertrophy and strength gains. However, it remains unclear whether protein quantity or nutrient timing is central to positive adaptations. This ...

    The influence of D-ribose ingestion and fitness level on performance and recovery Abstract Background: Skeletal muscle adenosine triphosphate (ATP) levels are severely depleted during and following prolonged high intensity exercise. Recovery from these lower ATP levels can take days, which can affect performance on subsequent days of exercise. Untrained individuals often suffer the stress and consequences of acute, repeated bouts of exercise ...

    The impact of sleeping with reduced glycogen stores on immunity and sleep in triathletes Abstract Purpose We investigated the effects of a 3-week dietary periodization on immunity and sleep in triathletes. Methods 21 triathletes were divided into two groups with different nutritional guidelines during a 3-week endurance training program including nine twice a day sessions with lowered (SL group) or maintained (CON group) glycogen availability ...

    Repeated High Intensity Bouts with Long Recovery: Are Bicarbonate or Carbohydrate Supplements an Option? The effects of varying recovery modes and the influence of preexercise sodium bicarbonate and carbohydrate ingestion on repeated high intensity performance, acid-base response, and recovery were analyzed in 12 well-trained males.They completed three repeated high intensity running bouts to exhaustion with intervening recovery periods of 25 ...

    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 ...
