Abstract Position Statement: The position of the Society regarding nutrient timing and the intake of carbohydrates, proteins, and fats in reference to healthy, exercising individuals is summarized by the following eight points: 1.

Nutrient timing and exercise: a review of the literature Introduction Previous research has demonstrated that the timed ingestion of carbohydrate, protein, and fat may significantly affect the adaptive response to exercise.

Nutrient timing: pre-exercise Nutritional considerations prior to exercise have traditionally examined the administration of CHO to maximize endogenous glycogen stores [ 2 — 6 ] and maintain serum glucose levels during endurance exercise [ 4 , 7 ]. Nutrient timing: during exercise Much like the consideration of pre-exercise nutrient supplementation, a majority of the literature which has examined the impact of nutrient administration during exercise has focused on aerobic exercise [ 33 — 36 ], with a lesser emphasis on nutrient administration during resistance exercise [ 37 — 41 ].

Glucose administration during endurance exercise The initial research which dealt with nutrient administration during exercise scrutinized the optimal delivery of CHO in an effort to sustain blood glucose.

Mixing carbohydrates to increase carbohydrate oxidation A fairly novel area of research has examined the impact of mixing various forms of CHO in an effort to promote greater levels of CHO oxidation during prolonged exercise. Adding protein or amino acids to carbohydrate during endurance exercise The addition of PRO to CHO during exercise has also been investigated as a means to improve performance and facilitate recovery.

Addition of protein, amino acids and carbohydrate during resistance exercise Delivering nutrients during single bouts of resistance exercise has been used to determine their impact on changes in muscle glycogen [ 40 ], mitigation of muscle damage [ 13 , 37 ], and promotion of an anabolic response [ 38 , 39 , 41 ].

Nutrient timing: post-exercise Many nutritional interventions have been considered to enhance recovery from exercise. Maximization of muscle glycogen re-synthesis Athletes who ingest 1.

Acute changes in amino acid kinetics and protein balance A single bout of resistance training modestly stimulates PRO synthesis, but also further stimulates PRO breakdown resulting in an overall negative PRO balance after exercise [ 75 , 76 ]; an effect which shifts PRO balance more towards neutral as training status progresses [ 76 ].

Post-exercise supplementation for promotion of training adaptations In an attempt to stimulate greater adaptations associated with resistance training researchers have investigated the impact of administering varying combinations of CHO and PRO after 1 — 3 h post-exercise each exercise bout over the course of training [ 8 , 10 , 32 , 84 — 91 ].

Conclusion The scientific literature associated with nutrient timing is an extremely popular, and thus ever-changing, area of research. References Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids.

Since muscles store carbohydrates and amino acids make up the structure of skeletal tissues, feedings are largely focused on carbohydrates and proteins. When studies compared the effects of carbohydrate or protein feedings on muscle protein synthesis, they found that together they have the greatest effect on increasing muscle protein synthesis.

Regarding muscle strength and growth, it has been found that the greatest effect of protein consumption is largely dependent on the last dose consumed.

Regular protein feedings every hours in doses of grams have shown the greatest benefit in improving muscle growth, and strength and leading to favorable changes in body composition.

However, regarding specific feeding windows, muscle protein synthesis is greatest immediately after up to 2 hours post-exercise. How much protein should be consumed in that time frame?

Can essential amino acids also do the trick? Doses of g of essential amino acids can also maximally stimulate muscle protein synthesis.

This can improve recovery and leads to favorable changes in body composition such as increases or maintenance in lean mass and decreases in fat mass. During exercise, frequent feedings of g of high GI carbs per hour of training can help increase performance, maintain normal blood glucose levels, and prevent early fatigue.

Post-exercise, protein should be consumed as soon as possible after exercise. However, you can still maximally stimulate muscle protein synthesis up to 2 hours post-exercise by consuming g of a rich protein.

When it comes to strength, recovery, and improved body composition it is recommended that protein be consumed in intervals of every hours to promote a positive state of nitrogen balance.

If your goal is to build muscle, carbohydrates, and protein should be consumed together. Nutrient timing can be employed at any level, however, if you are looking to gain a competitive edge and boost your performance, nutrient timing may be the key to your success.

Adding PRO to create a CHO:PRO ratio of 3 — may increase endurance performance and maximally promotes glycogen re-synthesis during acute and subsequent bouts of endurance exercise. Ingesting CHO alone or in combination with PRO during resistance exercise increases muscle glycogen, offsets muscle damage, and facilitates greater training adaptations after either acute or prolonged periods of supplementation with resistance training. Post-exercise ingestion immediately to 3 h post of amino acids, primarily essential amino acids, has been shown to stimulate robust increases in muscle protein synthesis, while the addition of CHO may stimulate even greater levels of protein synthesis.
