Soccer presents a metabolic challenge which is not necessarily matched by players' habitual dietary intake. To examine the effects of a bespoke diet, 22 players completed the Ball Sport Endurance and Sprint Test (BEAST(90mod)) protocol, followed by 4days of regulated nutritional intake. The diet consisted of 10g.kg(-1) body mass (BM) and 1.7g.kg(-1) BM of carbohydrate and protein, respectively. On day 5, players followed a prematch nutritional strategy of 7g.kg(-1) BM of carbohydrate and 1g.kg(-1) BM of protein divided into three meals and then repeated the BEAST(90mod). The players' pre-intervention intake consisted of 49 +/- 7.1% or 3.5g +/- 1.0g.kg(-1) BM for carbohydrate and 19 +/- 3.8% of total daily energy intake or 1.3g +/- 0.5g.kg(-1) BM for protein. Following the tailor-made dietary intervention, players ran an additional 887 +/- 233m (8.1%; d=2.4). An acute dietary intervention provided a positive effect on a valid simulated soccer match play test.
