IE 553 Lab. 3MEASURING AEROBIC CAPACITY AND
PREDICTING ENERGY EXPENDITURE
  • Group 3
  • Group members Billy, David, Rattachut
  • December 11th, 2006

Objectives
  • 1) Estimate an individual's aerobic capacity
    based upon oxygen consumption for bicycling task
    and lifting task
  • 2) Validate Garg's metabolic model, heart rate
    and Borgs subjective rating as means of
    estimation workload

Results
220 - age
Dynamic HR 95.3026.38 V02 (R-Sq 99.9)
hence, V02 - 3.61 0.0379 HR, at Max HR 192,
V02 3.6668
Static HR 88.3841.38 V02 (R-Sq
98.1) hence, V02 - 2.13 0.0241 HR, at Max
HR 192, V02 2.497

Conclusions
  1. Aerobic capacity based upon Vo2 and Garg model,
    HR and Borgs rating all ? monotonically with
    workload. Correlation coefficients all gt 0.95.
  2. In dynamic task, HR is most correlated to Vo2 in
    static task, Garg's model is most correlated to
    Vo2
  3. In dynamic task, Borgs rating deviates from Vo2
    largely in static task, HR deviates from Vo2
    most
  4. With same Vo2, static task shows larger HR than
    dynamic task.
