BACKGROUND: Long-term physical inactivity seems to cause many health problems. We studied whether persistent physical activity compared to inactivity has a global effect on serum metabolome towards reduced cardio-metabolic disease risk. METHODS AND RESULTS: Sixteen same-sex twin pairs (mean age 60 yrs) were selected from a cohort of twin pairs on the basis of their over 30-year discordance for physical activity. Persistently (≥5 years) active and inactive groups in three population-based cohorts (mean ages 31 to 52 years) were also studied (1037 age- and sex-matched pairs). Serum metabolome was quantified by nuclear magnetic resonance spectroscopy. We used permutation analysis to estimate significance of the multivariate effect combined across all metabolic measures; univariate effects were estimated by paired testing in twins as well as in matched pairs, in the cohorts, and by meta-analysis over all sub-studies. Persistent physical activity was associated with the multivariate metabolic profile in the twins (P=0.003), and a similar pattern was observed in all three population cohorts with differing mean ages. Isoleucine, α1-acid glycoprotein and glucose were lower in the physically active than in the inactive individuals (P
