Caffeine supplementation in doses between 3 and 6 mg/kg of body mass may improve jump height and sprint ability, particularly in female players, but individual response to caffeine must be considered.
Creatine may improve sprint, agility, and in female players, jump performance.
Protein supplementation can improve sprint and jump performance between matches, especially if protein ingested from food is not up to recommendations.
Beverages containing carbohydrates and electrolytes can be used as part of the strategies to achieve carbohydrate intake during training and match-days but used alone do not benefit athletic performance.
Tart cherry juice might be useful for maintaining athletic performance after matches that produce higher force loss and exercise-induced muscle damage, although polyphenols from the diet might attenuate the effects of tart cherry supplementation.
Nitrate-rich beetroot concentrate can attenuate performance decrease in the days following matches.
Further investigation with sodium bicarbonate alone is necessary, as supplementation protocols with elite players included other substances.
Finally, the available data does not support yohimbine supplementation or the use of Resurgex Plus® to improve athletic performance in elite soccer players.
