Position StatementThe following seven points related to the intake of protein for healthy, exercising individuals constitute the position stand of the Society. They have been approved by the Research Committee of the Society. 1) Vast research supports the contention that individuals engaged in regular exercise training require more dietary protein than sedentary individuals. 2) Protein intakes of 1.4 – 2.0 g/kg/day for physically active individuals is not only safe, but may improve the training… 

Muscle-Related Effect of Whey Protein and Vitamin D3 Supplementation Provided before or after Bedtime in Males Undergoing Resistance Training

There is increasing evidence that dietary protein intake with leucine and vitamin D is an important factor in muscle protein synthesis. This study investigated the combined effects of consuming whey

A Systematic Review of the Influence of Bovine Colostrum Supplementation on Leaky Gut Syndrome in Athletes: Diagnostic Biomarkers and Future Directions

It was revealed that vigorous exercise profoundly increases intestinal permeability, and BC supplementation helps to reverse gut permeability in athletes, suggesting that well-designed, placebo-controlled, and randomized studies are needed to evaluate the long-term safety and efficacy of BC supplementation in high-performance athletes.

Effects of protein supplementation in fitness world: A 12-week cross-over studio

Effect of isolated protein supplementation in young amateur athletes did not have affect the performance and body composition significantly and instead, training seems to influence the performance more the supplementation.

An observational study on the dietary intake, nutrition practices, hydration status and energy expenditure in competitive one-day cricket matches : a thesis presented in partial fulfillment of a Masters of Science in Human Nutrition, Massey University, Albany, New Zealand

This book presents a meta-analyses of the determinants of infectious disease in eight operation theatres across the United States over a period of 18 months in the period of May 21 to 29, 2009.

ISSN exercise & sports nutrition review update: research & recommendations

This updated review is to provide ISSN members and individuals interested in sports nutrition with information that can be implemented in educational, research or practical settings and serve as a foundational basis for determining the efficacy and safety of many common sport nutrition products and their ingredients.

Analysis and Screening of Commercialized Protein Supplements for Sports Practice

The conclusions of the study reveal that, due to a lack of knowledge or misleading advertising practices, supplements are often not used properly and the information provided is essential for both professionals and consumers to avoid the risks associated with consumption.

Leucine‑enriched essential amino acids promote muscle protein synthesis and ameliorate exercise-induced exhaustion in prolonged endurance exercise in rats

Background Long-term endurance exercise results in muscle damage as well as muscle protein synthesis (MPS). Recovery from endurance exercise leads to enhancement of physical performance and

Assessment of the diet and body composition of students recreationally training team sports

The results of the assessment of students’ diets indicate the necessity of nutritional education for people undertaking regular physical activity.

The effects of different temperatures of post-exercise protein-containing drink on gastric motility and energy intake in healthy young men

It is demonstrated that consuming protein-containing drink after exercise at 60°C increases energy intake and that this increase may be related to the modulation of the gastric motility.



pH-Dependent behaviour of soluble protein aggregates formed during heat-treatment of milk at pH 6·5 or 7·2

The pH-dependent behaviour of soluble protein aggregates produced by the pre-heating of reconstituted skim milk at 90 °C for 10 min was studied, and it was revealed that during acidification soluble casein in both control and heat-treated samples exhibits variations in its optical properties or size as previously shown with micellar casein.

Enhanced amino acid sensitivity of myofibrillar protein synthesis persists for up to 24 h after resistance exercise in young men.

The results suggest that resistance exercise performed until failure confers a sensitizing effect on human skeletal muscle for at least 24 h that is specific to the myofibrillar protein fraction.

Effect of exercise on protein requirements.

The weight of current evidence suggests that strength or speed athletes and endurance athletes should consume about 1.2-1.7 g protein/kg body weight, and there is no evidence that protein intakes in this range will cause any adverse effects.

Ingested protein dose response of muscle and albumin protein synthesis after resistance exercise in young men.

Dietary protein consumed after exercise in excess of the rate at which it can be incorporated into tissue protein stimulates irreversible oxidation, which suggested that the stimulation of MPS after resistance exercise may be related to amino acid availability.

Ingestion of whey hydrolysate, casein, or soy protein isolate: effects on mixed muscle protein synthesis at rest and following resistance exercise in young men.

It is concluded that the feeding-induced simulation of MPS in young men is greater after whey hydrolysate or soy protein consumption than casein both at rest and after resistance exercise; moreover, despite both being fast proteins, whey Hydrolysate stimulated MPS to a greater degree than soy after resistance Exercise.

Essential amino acids and muscle protein recovery from resistance exercise.

It is concluded that NEAA are not necessary for stimulation of NB and that there is a dose-dependent effect of EAA ingestion on muscle protein synthesis.

A Brief Review of Higher Dietary Protein Diets in Weight Loss: A Focus on Athletes

It is the central thesis of this review that dietary protein should be a nutrient around which changes in macronutrient composition should be framed and that higher protein diets for athletes are discussed.

Contemporary Issues in Protein Requirements and Consumption for Resistance Trained Athletes

An in depth analysis of contemporary issues in protein requirements and consumption for resistance trained athletes and the efficacy of protein supplements and whole food protein sources is presented.

Influence of protein intake and training status on nitrogen balance and lean body mass.

It is concluded that bodybuilders during habitual training require a daily protein intake only slightly greater than that for sedentary individuals in the maintenance of lean body mass and that endurance athletes require daily protein intakes greater than either bodybuilders or sedentary Individuals to meet the needs of protein catabolism during exercise.

Timing and distribution of protein ingestion during prolonged recovery from resistance exercise alters myofibrillar protein synthesis

The results indicate that repeated ingestion of 20 g of protein was superior for stimulating muscle protein synthesis during the 12 h experimental period, and shows that the distribution of protein intake is an important variable to promote attainment and maintenance of peak muscle mass.
