Vegan diets: practical advice for athletes and exercisers
Abstract: With the growth of social media as a platform to share information, veganism is becoming more visible, and could be becoming more accepted in sports and in the health and fitness industry. However, to date, there appears to be a lack of literature that discusses how to manage vegan diets for athletic purposes. This article attempted to review literature in order to provide recommendations for how to construct a vegan diet for athletes and exercisers. While little data could be found in the sports nutrition literature ...

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 study investigated the effect of total dietary protein content, whilst controlling for protein timing, on recovery in resistance trainees. Methods: ...

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 by
not having the ability to perform or recovery sufficiently to exercise on subsequent days. Conversely, trained individuals
may be able to ...

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 during the overnight recovery period. In addition to performance tests, sleep was monitored every night. Systemic and mucosal immune parameters as ...

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 min under the following conditions: sodium
bicarbonate, active recovery (BIC); carbohydrate ingestion, active recovery (CHO); placebo ingestion, ...

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 at position 34. The redox state of serum albumin has long been extensively investigated in terms of oxidative stress-related chronic diseases, with ...

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 greater anabolic effect on muscle than regular whey (WPC-80). This study compared the acute anabolic effects of ingesting 2 × 20 g of native whey ...

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 of mouth rinsing with a carbohydrate solution on executive function after sustained moderately high-intensity exercise. Methods: Eight young healthy ...
