Acute Effects of Long Interval Training With Varied Recovery Periods in Trained Runners

The aim of this study was to assess the effect of recovery period during long interval training (IT) on mechanical, physiological, perceptive, and neuromuscular parameters. Six men and six women trained runners (23.82 ± 7.83years; 56.27 ± 8.95kg; 167.55 ± 9.77cm) performed three treadmill interval sessions (4x4min) at 1% incline with 1min, 2min or self-selected recovery periods (SSrecovery) at highest possible average running speed. Velocity and distance increased by 2.5% (p
