  1. Values are presented as mean ± standard deviation
  2. EA: energy availability, RMR: resting metabolic rate, RMR ratio: measured/predicted RMR, FFM: fat free mass (kg)
  3. Predicted RMR was calculated by race, age, and sex specific formulae [30, 31] in J1; formula developed for Japanese adult female athletes accounting for FFM [33] in J2; Cunningham’s equation [32] in C
