Abstract

While often overlooked, hydration state plays an important role in performance and function. A hypohydrated state can bring about decrements in performance in nearly every aspect; 5.5 ± 1.0% for strength, 5.8 ± 2.3% for power, 8.3 ± 2.3% for endurance, and various decrements to flexibility. Hypohydration likely also stunts recovery, with exercise induced muscle damage and exercise associated muscle soreness being worsened. While no research suggests decrements in cognitive abilities, hypohydration encroaches on mood and potentially rate of perceived exertion (RPE). A state of dehydration may use up glycogen storage quicker, leading to inferior performance outcomes. Contrary to popular belief, regular consumption of creatine only increases body weight over a short term period. There is much debate on hydration protocols, mainly around drinking ad libitum or on a schedule. Hydration needs are highly dependent on the individual, and should be assessed on a case by case basis.
