Brief Summary

Aerobic capacity is critical for many athletes, especially for endurance athletes. Althgough several training methods are implemented by coaches to improve endurance performance, recovery following acute endurance training is not adequately studied. However, such information is crucial for coaches to effectively design the most favorable training program, to avoid muscle injuries and overtraining, and ultimately to improve performance of their athletes. This study aims to examine the acute effect of different continuous and HIIT training protocols on indices of metabolism, EIMD, neuromuscular fatigue and performance in middle- and long-distance runners.

Conditions

High Intensity Interval Training; Continuous Running; Control Condition

Outcome Measures

Primary Outcomes (11)

• Changes in Creatine kinase (CK)

  CK will be measured in plasma using a Clinical Chemistry Analyzer with commercially available kits.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in DOMS

  DOMS of knee extensors and knee flexors of both lower extremities will be measured during palpation of the muscle belly and the distal region after performing three repetitions of a full squat.

  Baseline (pre), post-, 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in blood lactate

  Lactate will be measured in capillary blood with a hand-portable analyzer.

  Baseline (pre), 4 minutes post-trial

• Changes in squat jump height

  Squat jump height will be measured with a photocells system.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in mean jump height during a 30 sec Bosco test

  Mean jump height will be measured with a photocells system.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in peak power during a 30 sec Bosco test

  Peak power will be measured with a photocells system.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in mean power during a 30 sec Bosco test

  Mean power will be measured with a photocells system.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in fatigue rate during a 30 sec Bosco test

  Fatigue rate will be estimated through the persent drop in mean jump height between the first 5 jumps and the last 5 jumps.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in maximal voluntary isometric contraction (MVIC)

  MVIC of the knee extensors and knee flexors will be measured on an isokinetic dynamometer.

  Baseline (pre), 1 hour post-, 2 hours post-, 3 hours post-, 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in peak concentric torque

  Concentric torque of the knee extensors and knee flexors will be measured on an isokinetic dynamometer.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial

• Changes in peak eccentric torque

  Eccentric torque of the knee extensors and knee flexors will be measured on an isokinetic dynamometer.

  Baseline (pre), 24 hours post-, 48 hours post-, 72 hours post-trial
