Eccentric exercise requires a higher heart rate (HR) for the same oxygen uptake (VO2) compared to concentric exercise. Individual adjustments in HR and cardiac output (Q) vary, necessitating personalized training prescriptions.

Area of Science:

  • Exercise Physiology
  • Cardiovascular Response
  • Sports Science

Background:

  • Eccentric (ECC) and concentric (CON) exercise elicit different cardiovascular responses despite identical oxygen uptake (VO2).
  • Understanding these differences is crucial for effective exercise prescription in rehabilitation and training.

Purpose of the Study:

  • To determine heart rate (HR) values for equivalent VO2 in ECC and CON cycling.
  • To assess interindividual variability in circulatory adjustments (HR, stroke volume (SV), cardiac output (Q)) between ECC and CON exercise modes.

Main Methods:

  • Eight healthy males performed incremental CON and ECC cycle exercises.
  • VO2 was measured via breath-by-breath gas analysis.
  • Cardiac output (Q) and SV were determined using beat-by-beat thoracic impedancemetry.

Main Results:

  • At matched VO2, stroke volume (SV) was similar, but HR was 17% higher and Q was 27% higher in ECC vs. CON cycling (P < 0.01).
  • Significant interindividual variability was observed in net HR and Q adjustments between ECC and CON exercise (CVs of 30-32%).

Conclusions:

  • Higher HR is required to achieve a given VO2 during ECC cycling compared to CON cycling.
  • Individualized HR prescription for ECC exercise is recommended, based on VO2/HR relationships from ECC incremental testing, to account for circulatory variability.
