Abbreviations: USG = urine-specific gravity; LD = long distance (>400 m distance events); SD = short distance (≤400 m distance events). Notes: 1 Data presented as n (%), where n = number of observations across the sport and gender by session; 2 Classifications based on the National Athletic Trainers’ Association position statement [17]; euhydrated ≤ 1.020; hypohydrated > 1.020; 3 Classifications based on previous recommendations to raise hypohydration classification thresholds to USG >1.025 to increase the specificity in detection [18]; 4 Classification based on the American College of Sports Medicine position stand guidelines [19]; Excessive dehydration > 2% body mass loss from water deficit.
