Abstract

BACKGROUND: In the general population higher levels of exercise capacity seem to protect the cardiovascular system with effects well beyond traditional risk factors. We hypothesize that this phenomenon, called "risk factor gap", could be ascribed to functional components, such as autonomic adaptation to aerobic training. METHODS: In 257 subjects (age 36.2±0.8 years) we measured VO₂peak (incremental cycling exercise), together with arterial pressure and autonomic proxies (baroreflex gain, R-R variance and standing induced increase in marker of excitatory oscillatory regulation of the SA node, ALF_RRnu). RESULTS: Autonomic proxies appeared significantly correlated with indicators of aerobic fitness (age and gender corrected correlation between VO₂peak, baroreflex gain: 7=0.277, P2peak (poor, medium and good). Autonomic indices and arterial pressure appeared significantly ordered with categories of VO₂peak (P
