Abstract Opinion on the role of protein in promoting athletic performance is divided along the lines of how much aerobic-based versus resistance-based activity the athlete undertakes. Athletes seeking to gain muscle mass and strength are likely to consume higher amounts of dietary protein than their endurance-trained counterparts. The main belief behind the large quantities of dietary protein consumption in resistance-trained athletes is that it is needed to generate more muscle protein… 
Protein intake for athletes and active adults: Current concepts and controversies
Within the broad framework of recommended ranges and being cognisant of overall energy and other macronutrient intakes, a personalised and periodised approach to nutrition is required depending on an individual's sport, training volume, phase and goals.
Beyond muscle hypertrophy: why dietary protein is important for endurance athletes.
The role of protein is focused on in facilitating optimal recovery from, and promoting adaptations to strenuous endurance-based training, as well as how the manipulation of dietary protein can facilitate muscle remodelling by promoting muscle protein synthesis.
Considerations for protein intake in managing weight loss in athletes
It is shown that higher protein intakes during periods of energy restriction can enhance fat-free mass preservation, particularly when combined with exercise, and athletes aiming to reduce fat mass and preserve FFM should be advised to consume protein intakes in the range of ∼1.8–2.7 g kg−1 d−1.
Nutrition for sports performance: issues and opportunities
There is an increasing recognition of the role of the brain in determining exercise performance: various nutritional strategies have been proposed, but with limited success, and nutrition strategies developed for use by athletes can also be used to achieve functional benefits in other populations.

So called low-glycogen training, however, can lead to better adjustment/adaptation processes in selected training stages and can increase performance ability.
Impact of Protein Intake on Protein Metabolism and Exercise Performance in Endurance-Trained Males
Background: Current recommendations for athletes consider dietary protein requirements that maintain nitrogen (i.e. protein) balance rather than an optimal dosage to enhance metabolism and exercise
Sprinting: optimizing dietary intake.
There is evidence to support the use of a small number of products to assist sprinters in the training and/or competition environment, but these need to be trialed in training to assess tolerance and likely individual performance response.
Protein Requirements for Master Athletes: Just Older Versions of Their Younger Selves
The argument is put forth that Master athletes have similar muscle characteristics, physiological responses to exercise, and protein metabolism as young athletes and, therefore, are unlikely to have protein requirements that are different from their young contemporaries.
Protein metabolism and physical training: any need for amino acid supplementation?
This review will examine the results obtained under endurance and resistance type of exercise while consuming single or repeated doses of various ingestions of protein products (full meat, essential amino acids, specific amino acids and derivatives, vegetarian food).

Higher protein diets have quite consistently been shown to result in greater weight loss, greater fat loss, and preservation of lean mass as compared with "lower" protein diets, and a framework for understanding dietary protein intake within the context of weight loss and athletic performance is laid out.
Gender differences in leucine kinetics and nitrogen balance in endurance athletes.
The current Canadian RNI for protein is inadequate for those who chronically engage in endurance exercise and leucine kinetics during exercise is concluded.
Exercise training and protein metabolism: influences of contraction, protein intake, and sex-based differences.
The current understanding of muscle protein turnover in response to exercise and feeding is summarized and potential sex-based dimorphisms are highlighted and the underlying anabolic signaling pathways and molecules that regulate these processes are examined.
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.
Evaluation of protein requirements for trained strength athletes.
Protein requirements for athletes performing strength training are greater than for sedentary individuals and are above current Canadian and US recommended daily protein intake requirements for young healthy males.
The Role of Milk- and Soy-Based Protein in Support of Muscle Protein Synthesis and Muscle Protein Accretion in Young and Elderly Persons
Evidence is shown that whey protein is better able to support MPS than is soy protein, a finding that may explain the greater ability of wheyprotein to support greater net muscle mass gains with resistance exercise.
Failure of protein to improve time trial performance when added to a sports drink.
Adding 2% protein to a 6% carbohydrate drink provided no additional performance benefit during a task that closely simulated the manner in which athletes typically compete, but improving an 80-km TT performance in trained male cyclists was found.
Coingestion of protein with carbohydrate during recovery from endurance exercise stimulates skeletal muscle protein synthesis in humans.
It is concluded that ingesting protein with CHO during recovery from aerobic exercise increased muscle FSR and improved WBNB, compared with feeding strategies that provided CHO only and were matched for total CHO or total energy intake.
Resistance training reduces whole-body protein turnover and improves net protein retention in untrained young males.
A program of resistance training that induced significant muscle hypertrophy resulted in reductions of both whole-body PS and PB, but an improved NPB, which favoured the accretion of skeletal muscle protein, suggesting that dietary requirements for protein in novice resistance-trained athletes are not higher, but lower, after resistance training.
Effect of dietary protein content during recovery from high-intensity cycling on subsequent performance and markers of stress, inflammation, and muscle damage in well-trained men.
A nutritive effect of post-exercise protein content was not discernible short term, but a delayed performance benefit was observed following protein-enriched high-carbohydrate ingestion.
