Adherence
Physical activity is inversely associated with insulin resistance and circulating metabolite levels, but these associations are largely attenuated when adjusting for HOMA-IR, suggesting physical activity improves insulin sensitivity directly rather than by lowering specific metabolite levels.
Exercise improves insulin sensitivity directly. While your blood tests might show changes in amino acids after exercising, these changes are likely just a reflection of your improved metabolic health, not the primary mechanism. Don't worry if your amino acid levels don't drop perfectly; focus on the consistency of your physical activity.
Physical activity was inversely associated with insulin resistance index as well as several metabolites... The physical activity associations with metabolites were of smaller magnitude than with HOMA-IR and were attenuated or rendered nonsignificant upon conditioning on HOMA-IR.
Why this rating
Large cohort, clear statistical adjustment, but observational nature prevents definitive causal claims about the direction of effect.

More from this paper
- Elevated circulating levels of branched-chain amino acids (Leu, Ile, Val) and aromatic amino acids (Phe, Tyr) are strongly associated with insulin resistance (HOMA-IR) in young, normoglycemic adults, with associations being significantly stronger in men and in women only when abdominally obese.Good
- Genetic variants that regulate circulating amino acid and lipid levels generally do not cause insulin resistance, suggesting that elevated amino acids are likely secondary markers of insulin resistance rather than causal drivers.Good
