Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
OTHER	Sprint Interval Training	The Sprint Interval Training (SIT) training consists of 3 successive blocks of 5 training sessions each. The sessions are 24 to 48 hours apart. . One block lasts two weeks. After the end of one block, the following block begins the day after. The Sprint Interval Training lasts 6 weeks. Each session consists of a series of sprints, the number of which varies from 8 to 14. Thus a session will last from 30 to 45 min approximately So, the time frame of this study is Baseline, Block 1, Block 2 and Block 3 (Not in day or week or month)
