Mean non-protein respiratory quotients during and after the aerobic load for each of the genetic classifications.

SD: Standard deviation. One-way analysis of variance (ANOVA), significance p<0.05. U: Mann–Whitney test, significance p<0.05. Asterisk (*) indicates the values that significantly differ in the same stage.
K+: K allele carriers. K−: K allele non-carriers. R+: R allele carriers. R−: R allele non-carriers. K+/R+: K and R allele carriers. K+/R−: K allele only carriers. R+/K−: R allele only carriers.

SD：标准差（Standard deviation）。采用单因素方差分析（one-way analysis of variance, ANOVA），显著性检验阈值设为p<0.05。U检验：曼-惠特尼检验（Mann–Whitney test），显著性检验阈值同样为p<0.05。星号（*）用于标注同一阶段中存在显著差异的检测数值。
K+：携带K等位基因（allele）的个体；K−：未携带K等位基因的个体。R+：携带R等位基因的个体；R−：未携带R等位基因的个体。K+/R+：同时携带K与R等位基因的个体；K+/R−：仅携带K等位基因的个体；R+/K−：仅携带R等位基因的个体。
