Summary
This study confirms the reproducibility of an intermittent running test. Pacing strategy, perceived exertion, heart rate, and lactate levels remained consistent between test and retest sessions.
Area of Science:
- Exercise Physiology
- Sports Science
Background:
- Reproducibility of physiological testing is crucial for reliable performance assessment.
- Intermittent running tests are commonly used to evaluate endurance capacity.
- Understanding pacing strategy effects on test reliability is important.
Purpose of the Study:
- To assess the reproducibility of an intermittent running test with a self-selected pacing strategy.
- To determine the reliability of physiological and perceptual measures during this test.
Main Methods:
- Ten participants completed a crossover, test-retest study.
- An intermittent running test involved 3-minute sets at 1 km/h above Onset Blood Lactate Accumulation until exhaustion.
- Pacing strategy involved self-selected rest time intervals (RTI) between sets.
Main Results:
- No statistically significant differences (p>0.05) were found between test and retest for RTI, rating perceived exertion (RPE), heart rate (HR), blood plasma lactate concentration ([La]p), and time to exhaustion.
- Good intraclass correlation coefficients were observed for all measured variables.
Conclusions:
- The intermittent running test, incorporating a self-determined pacing strategy, demonstrates high reproducibility.
- Physiological and perceptual responses are reliable across repeated testing sessions.
