Abstract in brief

  • This study examined how different work durations in self-paced interval running affect physiological responses like VO2 max, heart rate, perceived exertion, and blood lactate levels in well-trained runners, finding that longer intervals (up to 6 minutes) generally lead to higher physiological strain but perceived exertion remains consistent around 17 on the RPE scale.
  • Runners achieved their highest VO2 and heart rate during 4-minute intervals, suggesting that this duration might be optimal for maximizing physiological load without increasing perceived effort.
  • Despite increases in perceived exertion during sessions, blood lactate levels remained similar across all interval durations, indicating that perceived effort does not directly correlate with lactate accumulation in this context.]

It is ~20 years since this simple descriptive study of physiological and perceptual responses to different HIT prescriptions was published, but I still go back to it myself: https://t.co/t3bcXN5sWb
