There exists a large body of scientific evidence to support protein intakes in excess of the recommended dietary allowance RDA 0. Diet-induced weight loss with as low as possible ratio of skeletal muscle to fat mass loss is a situation we refer to as high-quality weight loss.

We propose that high-quality weight loss is often of importance to elite athletes in order to maintain their muscle engine and shed unwanted fat mass, potentially improving athletic performance. Current recommendations for protein intakes during weight loss in athletes are set at 1.

However, the severity of the caloric deficit and type and intensity of training performed by the athlete will influence at what end of this range athletes choose to be. Other considerations regarding protein intake that may help elite athletes achieve weight loss goals include the quality of protein consumed, and the timing and distribution of protein intake throughout the day. This review highlights the scientific evidence used to support protein recommendations for high-quality weight loss and preservation of performance Recommendation International Sport Marketing athletes.

Elite athletes regularly expend high amounts of energy during training and competition. Weight loss in elite athletes, if desired, is commonly achieved by the introduction of a caloric deficit that consists of restriction of dietary energy combined with their training.

Lean body mass, a significant proportion of which is skeletal muscle, is critical for good metabolic function i. Therefore, to reduce the negative consequences of skeletal muscle loss Recommendation International Sport Marketing performance that may accompany caloric restriction, strategies to promote high-quality weight loss i. The responses are, however, transient with feeding and Recommendation International Sport Marketing within hours of not eating, leading to periods of negative energy balance. Thus, in energy balance, over the course of the day periods of positive and negative protein balance are roughly equal, resulting in stable skeletal muscle mass.

To offset this negative net muscle protein balance, strategies such as increasing protein intake and the practice of resistance exercise that could improve muscle protein balance during dietary energy restriction are therefore critical for the maintenance of LBM. During dietary energy restriction in athletes, a high degree of satiety is especially helpful and may promote compliance to reduced energy intake despite higher energy expenditure. Furthermore, many protein-containing foods are nutrient-dense foods; for example, protein from animal sources e. The purpose of this review is to highlight the current body of knowledge around the role of higher dietary protein intakes and dietary supplements during hypocaloric weight loss on LBM retention and fat mass loss in elite athletes.

Read more additional weight management strategies in athletes beyond protein and dietary supplements, we refer the interested reader to a brief review Manore, The recommended dietary allowance for protein, determined by the nitrogen balance method is currently set at 0. Importantly, in situations of energy restriction, the percentage of total energy from protein will change Personal Assignments On The Deadline on the severity of the energy deficit. However, it is important to note that most higher protein weight loss diets still provide protein that is well within the AMDR. Current recommendations for protein intake in athletes during caloric restriction span a large range.

For example, a systematic review reported that resistance trained athletes require 1. Of note, the maintenance of LBM during caloric restriction is affected by a number of different factors that may influence the optimal level of protein intake. Firstly, the more severe the caloric deficit i.

Finally, the training status and volume of work being performed by the athletes may be a factor in determining Recommendation International Sport Marketing protein intakes. For example, the energy expenditure during exercise training will contribute to the caloric deficit and should be accounted for during the weight loss diet. The indicator amino acid oxidation IAAO method is a technique for determining protein requirements by measuring the oxidation of an indicator amino acid in response to differing protein intakes.

Finally, an RDA of 2. Thus, the IAAO method may be useful to determine optimal protein recommendations for athletes undergoing varied Matketing protocols and caloric restriction interventions. To date, there are only a handful of studies investigating the effect of protein quantity on MPS and body composition during dietary energy restriction in physically active adults. Equally as impressive was that the higher protein 2.]
