Actual (reported)Dietary protein has been shown to be important to support physical training. For occupational demands such as military training, new recruits often fail to meet the recommended protein intake during basic training (BT), with negligible amounts consumed in the evening. As such, individuals undertaking BT may require higher intakes than the general population.This study assessed the influence of a daily bolus of protein prior to sleep on performance adaptations, body composition and recovery in British Army recruits.
