Evaluation of Aerobic Capacity and Workload Predictors on a Bicycle Task

Estimating subject's aerobic capacity through ventilation and heart rates on a bicycle task. Validating Garg's Model for static lifting tasks. Assessing HR, Borg’s Rating, and VO2 as workload predictors from the results showing maximum VO2 and HR values and conclusions drawn from the study. Heart rate and VO2 are linearly correlated with energy expenditure, making them valid workload measures compared to Borg's RPE.

Presentation Transcript

  1. To estimate our subject's aerobic capacity based upon ventilation and heart rates using a bicycle Confirm Garg's Model based on a static lifting task Evaluate HR, Borg’s Rating and VO2 as valid predictors of workload Objectives

  2. Results Max VO2 = 2.42 Max VO2 = 3.53 Max HR = 192 Estimation of the Ventilation • Ventilation = 0.54 + 1.49 number of blocks

  3. Conclusions • For the static lifting, the heart rate increases faster than the dynamic. • The estimation of E should be more accurate, for we are estimating from the real data. The Garg’s model is a generalized model. • The heart rate and the VO2 correlate linearly with energy expenditure. They both seem to be valid measures of workload. • Borg's RPE is not as good a valid measure of workload as heart rate or VO2 .
