Summary
Athletic performance at 610 m altitude showed a lower peak oxygen uptake (VO2) but similar work output. This suggests altitude impacts aerobic fitness testing, even at lower elevations.
Area of Science:
- Sports Science
- Environmental Physiology
- Exercise Physiology
Background:
- Anecdotal evidence suggests the Australian Institute of Sport's 610 m altitude may affect athletic performance.
- Lower air resistance at altitude could influence air-braked ergometer mechanics.
Purpose of the Study:
- To compare rowing ergometer performance at sea level (SL) versus Canberra (CB) at 610 m altitude.
- To investigate the physiological effects of low-altitude environments on athletic performance.
Main Methods:
- Fourteen male junior rowers completed two six-minute all-out rowing ergometer tests.
- Tests were conducted in random order at sea level and in Canberra (610 m).
- Performance metrics including peak VO2 and work completed were measured.
Main Results:
- Peak VO2 was significantly lower in Canberra (3.97 L/min) compared to sea level (4.12 L/min).
- Work completed was similar at both locations (1666 m in CB vs. 1672 m in SL).
- Greater oxygen extraction at altitude partially compensated for lower partial pressure of inspired oxygen (PIO2).
Conclusions:
- A lower peak VO2 at 610 m altitude did not significantly reduce rowing performance.
- Increased oxygen extraction at this low altitude partially compensated for reduced PIO2.
- Altitude must be considered when interpreting aerobic fitness test results.
