Abstract

Middle-distance athletes require a high carbohydrate intake to support training and racing intensity.

Training volume, duration, and intensity in middle-distance athletes utilize all energy-producing pathways and muscle fiber types.
Energy expenditure varies significantly across training phases, necessitating adjustments in total energy intake to maintain ideal body composition.
Immediate carbohydrate consumption is crucial for optimizing recovery by maximizing glycogen resynthesis rates.
For longer-term recovery, consuming protein alongside carbohydrates is recommended.
Supplementation with beta-alanine or sodium bicarbonate may enhance buffering capacities, potentially leading to a small performance increase.
Future research should explore the effects of different exercise and nutrition stimuli on gene and molecular signaling pathways related to muscle adaptation.

Middle-distance athletes implement a dynamic continuum in training volume, duration, and intensity that utilizes all energy-producing pathways and muscle fibre types. At the centre of this periodized training regimen should be a periodized nutritional approach that takes into account acute and seasonal nutritional needs induced by specific training and competition loads. The majority of a middle-distance athlete's training and racing is dependant upon carbohydrate-derived energy provision. Thus, to support this training and racing intensity, a high carbohydrate intake should be targeted. The required energy expenditure throughout each training phase varies significantly, and thus the total energy intake should also vary accordingly to better maintain an ideal body composition. Optimizing acute recovery is highly dependant upon the immediate consumption of carbohydrate to maximize glycogen resynthesis rates. To optimize longer-term recovery, protein in conjunction with carbohydrate should be consumed. Supplementation of beta-alanine or sodium bicarbonate has been shown to augment intra- and extracellular buffering capacities, which may lead to a small performance increase. Future studies should aim to alter specific exercise (resistance vs. endurance) and/or nutrition stimuli and measure downstream effects at multiple levels that include gene and molecular signalling pathways, leading to muscle protein synthesis, that result in optimized phenotypic adaptation and performance.
