In all sports, skill is used as an umbrella term that includes not only physical performance of a particular skill but also the complex interaction of cognitive and technical ability to respond to the multitude of scenarios that occur in every match. However, when competing in team sports participants experience, to different degrees, physical and mental fatigue that has a negative impact on the performance of sports specific skills. As nutrition counter measure, the ingestion of appropriate quantities of carbohydrate, at appropriate times, has been shown to maintain or benefit aspects of skill performance. The mechanisms underpinning this preservation of skill with carbohydrate feedings involve a complex series of events between brain and skeletal muscle that interact to minimize the impact of physical and mental fatigue. Although these questions are specific to soccer research, many of the principles are directly transferable to other “stop-and-go” team sports.

The ketone bodies acetoacetate and β-hydroxybutyrate have wide-ranging metabolic and molecular effects on organs such as the brain, heart and skeletal muscle, some of which are suggestive of benefits to athletes in terms of performance and recovery. The recent development and increasing commercial availability of ingestible forms of ketone bodies as exogenous ketone supplements has amplified interest in these compounds. A variety of compounds classified as exogenous ketone supplements are now available and have been subject to several studies in exercise performance and recovery contexts in human participants. While there are mechanistic bases for potential beneficial effects of exogenous ketone supplements in various athletic contexts, most studies to date have failed to observe benefits to performance or recovery.

Because of the discussions on more sustainable food production and the need to improve lifestyle and health, there is a growing interest in the transition towards consuming a more plant-based diet. As a result, daily protein intake will be derived more from the consumption of plant-based proteins at the expense of animal-based proteins. There are many questions on whether this has impact on the capacity of an athlete to recover and recondition following exercise. So far, basic research indicates that the ingestion of plant-derived proteins may not stimulate muscle protein synthesis to the same extent when compared to the ingestion of an equivalent amount of animal-derived proteins. The proposed lesser anabolic properties of plant- versus animal-based proteins have been attributed to differences in protein digestion and amino acid absorption kinetics. Furthermore, most plant-derived proteins have lower essential amino acid contents and can be deficient in one or more specific amino acids. However, it should be noted that very few studies have directly compared muscle protein synthesis rates following the ingestion of plant- versus high quality animal-derived proteins. Theoretically, a lower bioavailability and/or functionality of plant-based protein sources and/or plant-derived protein concentrates may result in greater daily protein requirements for athletes transitioning towards a (more) plant-based diet. However, as athletes typically consume a diet that provides more than 1.5 g protein per day, a lesser protein bioavailability or protein quality will unlikely compromise muscle conditioning in athletes adopting a (more) plant-based diet. However, when athletes are changing to a plant-based diet under conditions of low(er) energy and/or protein intake, a sports dietitian should be consulted to ensure ample protein provision.
