Effects of dietary supplements on athletic performance in elite soccer players: a systematic review
How dietary supplements may affect athletic performance in top soccer players
AI simplified
Abstract
A total of 18 studies involving elite soccer players were reviewed for the effects of various dietary supplements on athletic performance.
- Caffeine supplementation at 3 to 6 mg/kg of body mass may enhance jump height and sprint ability, especially in female players, though responses can vary individually.
- Creatine supplementation could improve sprinting, agility, and jump performance in female soccer players.
- Protein intake may enhance sprint and jump performance between matches when dietary protein is insufficient.
- Carbohydrate and electrolyte beverages can support carbohydrate intake during training and match days but do not independently enhance performance.
- Tart cherry juice might help maintain performance after matches that lead to muscle damage, although dietary compounds could lessen its effectiveness.
- Nitrate-rich beetroot juice may reduce performance decline in the days following matches.
