Table 3 Comparison of resting metabolic rate and ratio between groups according to energy availability level

From: Association of energy availability with resting metabolic rates in competitive female teenage runners: a cross-sectional study

   EA (kcalkg−1 FFMd−1)   
  All > 30 < 30 p Effect size
N 18 12 6   
RMR      
(kcalkg−1 FFMd−1) 26.9 ± 2.4 27.4 ± 2.6 25.9 ± 1.7 0.231 0.59
RMR ratio      
J1 0.90 ± 0.08 0.90 ± 0.09 0.90 ± 0.07 0.969 0.02
J2 0.96 ± 0.08 0.98 ± 0.08 0.93 ± 0.06 0.288 0.52
C 0.77 ± 0.06 0.77 ± 0.07 0.77 ± 0.04 0.878 0.05
  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
