Objective:

To compare peak oxygen consumption (VO2) and heart rate (HR) during treadmill (TM) running and exercise on an elliptical trainer (ET).

Design:

A graded exercise test (GXT) during TM running and ET exercise.

Participants:

Physically active college students (N = 14; 25 ± 4.6 years). Each completed a TM GXT and ET GXT on separate days.

Results:

There were no differences in either VO2peak or peak HR between TM (53.0 ± 7.7 ml · kg–1 · min–1, 193.4 ± 9.4 bpm) and ET (51.6 ± 10.7 ml · kg–1 · min–1, 191.2 ± 11.5 bpm; P > .05). Correlations between HR and VO2 data for all stages of exercise for all subjects were similar between machines (ET: r = .88; TM: r = .95; P > .05).

Conclusion:

No adjustments to the target HR used during TM running are necessary when using the ET.
