Abstract
The Cardio-Respiratory Response Following a 8-Week Aerobic Interval Training Program in Trained Adolescents
Cross-sectional studies provide some direction on the underlying training adaptations. The development of accurate and reliable non-invasive stroke volume (SV) measurement techniques helped differentiate endurance trained subjects who presented larger maximum oxygen consumption (VO2max) than sedentary and moderately trained people. In fact, it generally established that aerobic exercise training results in an increase in SV at rest but also at the maximal aerobic intensity (or p VO2max) despite similar peak exercise heart rates (HR). Thus, aerobic endurance trained subjects achieve higher cardiac output values (CO) compared to untrained and moderately trained subjects. Furthermore, a high VO2max is also associated with high stroke volume (SV) in individuals who undergo chronic exposure to aerobic endurance exercise compared to sedentary subjects.
