Excerpt
An elliptical stationary exercise machine (EM, Precor, USA) has been developed to simulate running kinematics while eliminating the foot-ground impact. To determine if peak oxygen consumption (VO2peak) and heart rate (HRpeak) were similar during treadmill running (TMR) and EM exercise, 13 subjects (n=4 females, 58±12 kg, 24±5 yr, n=9 males, 77±10 kg, 25±5 yr) completed 2 graded exercise tests (GXT). One GXT was completed per test day with tests 48 hours to 1 week apart. Test time-of-day was similar between test days and test order randomized. During the TMR GXT, speed and/or ramp height were increased each stage, while during EM GXT, cadence or machine resistance level was increased each stage. Variables were tested via repeated measures ANOVAs. There was no difference in VO2peak or HRpeak between TMR (53±8 ml·kg−1·min−1, 193±10 bpm) and EM (52±11 ml·kg−1·min−1, 191±12 bpm) (p>0.05) and no interaction between mode of exercise and gender (p>0.05). No differences were observed between time to exhaustion between modes of exercise (p>0.05). For the population tested, the EM and TMR GXTs resulted in comparable peak responses, indicating that the EM may be a suitable alternative to running.
