Despite a body mass loss of 4.4 kg during Phase 1, the athlete was still required to lose 9.6 kg in the next 7 days. In Phase 2 of the athlete’s strategy, he subsequently underwent a 5-day water-loading protocol

prevalence of players in various categories of relative body mass change following matches. These data show that a wide range of players experienced 1–2% reduction in body mass (up to 12), and an additional two to eight players experienced body mass loss of >−2%.

adequate fluid intake, sweat loss may result in hypohydration (>2% body-mass loss) impairing athletic performance, cognitive performance, and physiological function ( Belval et al., 2018 ; Casa et al., 2015 ; Lopez et al., 2011 ; Rav-Acha et al., 2004 ). Dehydration precipitated by sweat-based fluid

separating samples from runs that resulted in 2.00–2.99% or ≥3.00% body mass loss. The rationale for dividing samples into these categories was made so lower and higher sweat losses would be split into groups of close sizes with a large n (vs. splitting data into tertiles or quartiles) and to provide whole

Thirty-eight collegiate (40.4%) and 44 professionals (59.5%) correctly chose fluid consumption should be based on individual sweat rate, sport intensity, and tolerance. Five collegiate (5.3%) and
