Problems of sleep disorders and disruption are common particularly in Arab populations, and sleep insufficiency hinders the pursuit of high performance and optimal recovery following training and competition. Adequate investigation and personalization of dietary interventions to enhance sleep and recovery requires employing suitable methods of experimentation that involves repeated administration of treatment and placebo conditions, following a replicate crossover trial design, for derivation of athlete by dietary treatment interaction to inform decisions of supplementation dosing personalization embedded into routine service provision. Nevertheless, no study in sports performance explored this and other issues following adequate methodology and research design requirements. Accordingly, the project seeks to investigate the main effects and whether inter-individual variability exists in free-living objective sleep and recovery responses to novel nutritional blend supplementation in the form of a mixed juice (15000 mg cherry juice concentrate, 220 mg cherry extract, 250 mg cocoa extract, 200 mg of tryptophan, 100 mg of L-5-Hydroxytryptophan, 3000 mg of glycine, 300 mg of magnesium, 200 mg of theanine) adopting a replicate crossover design.
