Abstract
Purpose: To examine the reliability of HR measures obtained during the 6 min Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1), and following a 3 min passive recovery, within a group of highly trained youth soccer players.
Methods: Eight players, completed three separate 6 min Yo-Yo IR1 tests, with a passive recovery, over a two week period. Measures of absolute heart rate (bpm) and relative HR (%HRmax) were obtained at the 3rd and 6th min of the test, with measures relative to the end HR (%HRend) 10, 20, 30, 60, 90 and 180 seconds, during the 3 min passive recovery. Variability in HR measures were assessed across successive trials (trial 1 vs. 2 and trial 2 vs. 3) and across all 3 trials, using the intraclass correlation coefficient (ICC), coefficient of variation (CV) and typical error (TE). Results: HR measures obtained during the 6 min Yo-Yo IR1 test displayed good levels of reliability (ICC: 0.95-0.98, CV: 1.1-1.3% and TE: 0.96-2.44).
Results, display a potential learning effect, with lower levels of variability between trial 2 vs. trial 3. Examination of %HRend obtained during the passive 3 min recovery demonstrated an increased variance, as the passive recovery period progressed.
Conclusion: The 6 min Yo-Yo IR1 test presents a novel and potentially practical approach to regularly assessing youth soccer players’ physical response to intermittent exercise. Practitioners and researchers should however, consider the need for appropriate familiarisation when undertaking this test.
