Abstract

Purpose: To better understand the energy and carbohydrate (CHO) requirements of a professional goalkeeper (GK) in elite soccer, the authors quantified physical loading, energy expenditure (EE), and energy intake (EI) during a 2-games-per-week in-season microcycle.

Methods: Daily training and match loads were assessed in a professional GK (age 26 y, height 191 cm, body mass 85.6 kg) from the English Premier League using global positioning systems (GPS) and ProZone®, respectively. Assessments of EE (using the doubly labeled water method) and EI (using food diaries supported by the remote food photographic method and 24-h recalls) were also completed.

Results: Physical loading was greater on match days than training days as inferred from total distance (4574 [432] vs 1959 [500] m), average speed (48 [5] vs 40 [4] m/min), and distance completed when jogging (993 [194] vs 645 [81] m) and running (138 [16] vs 21 [20] m). Average daily energy and macronutrient intake appear reflective of a self-selected “low-CHO” diet (energy 3160 [381] kcal, CHO 2.6 [0.6], protein 2.4 [0.4], fat 1.9 [0.3] g/kg body mass). Mean daily EE was 2894 kcal.

Conclusions: The average daily EE of this professional GK was approximately 600 kcal/d lower than that previously reported in outfield players from the same team. Such data suggest that the nutritional requirements of a GK should be carefully considered depending on the required daily and weekly loading patterns.
