Figure 3. Serum Metabolome Measures in Individuals With High Fitness Compared With Individuals With Low Fitness According to Aerobic Fitness and Muscular Strength.

The points and lines indicate the differences in individuals with high fitness compared with individuals with low fitness in medians and their bootstrapped 95% CIs scaled in SDs of the pooled data of all 580 participants. Blue indicates serum levels that were statistically significantly higher among individuals with high fitness compared with those with low fitness; navy, serum levels that were statistically significantly lower among individuals with high fitness compared with those with low fitness; and orange, differences were not statistically significant. BCAA indicates branched-chain amino acid; FA, fatty acid.

^aω-3 FA ratio is the ratio of ω-3 FAs to total FAs.

^bω-6 FA ratio is the ratio of ω-6 FAs to total FAs.
