Summary

Cardiorespiratory variables measured during ramp exercise tests are reproducible and comparable to step-wise incremental tests. Peak exercise capacity was similar, with ramp tests showing higher peak power output.

Area of Science:

  • Exercise Physiology
  • Cardiorespiratory Fitness Assessment

Background:

  • Reproducibility of exercise testing protocols is crucial for accurate assessment.
  • Comparing ramp and step-wise incremental protocols provides insights into exercise physiology.

Purpose of the Study:

  • To assess the reproducibility of cardiorespiratory variables using a ramp protocol.
  • To compare cardiorespiratory variables obtained from ramp and step-wise incremental protocols.

Main Methods:

  • Twenty healthy adolescents and young adults underwent two cycle-ergometer tests, one with each protocol.
  • Twelve subjects repeated the ramp protocol test to assess reproducibility.

Main Results:

  • Cardiorespiratory variables measured during ramp exercise were reproducible.

  • Peak values from ramp and step-wise protocols were similar, except for higher peak power in ramp tests.
  • Significant correlations were found between protocols at equivalent submaximal workloads.

    • Conclusions:

    • The ramp exercise protocol is a reproducible method for assessing cardiorespiratory variables.
    • Ramp and step-wise protocols yield comparable results for peak exercise capacity and cardiorespiratory measures.
    • Ramp protocol offers a valid alternative for exercise testing in adolescents and young adults.
