简要总结
The present study aims to analyse first, the acute effects generated by a single bout of Sprint Interval Training (SIT) and, secondly, the effects of a long-term intervention on sedentary participants.
详细描述
The main goal is to determine the optimal dose of high-intensity exercise that enhances the best physiological adaptations.
The cumulative effects of SIT, will be assessed by a series of measures placed throughout the time-course (before, after the 1st , the 2nd and the 3rd block of SIT). Those measures consist of physiological measurements (VO2max), neuromuscular capacities (force-velocity profile) the autonomic nervous system responses (heart rate variability) and blood markers (lactate, Creatine phosphoKinase (CK), cytokinases, µRNA). Acute effects will be measured in the familiarisation sessions (after short (8 sprints) and long (14 sprints) sets) by performing a battery of neuromuscular, perceptual, and autonomic nervous system tests before and after the single session of SIT.
