Uses of a Bicycle Ergometer

Bicycle ergometers are used to measure the physical fitness and energy output of athletes, astronauts and other professionals whose performance depends upon their strength and endurance. Performance on a bicycle ergometer is a reliable indicator of fitness, because a bicycle requires nearly identical energy output regardless of age and physiology. The rider remains stationary while riding, allowing heart rate and other functions to be continuously evaluated.

Test Physical Fitness
- Monitoring equipment may be attached to the subject while he or she is riding the bicycle to measure heart rate, pulse, oxygen uptake, and other signs of physical strain. Since the energy output required to operate a bicycle is equivalent across genders and age groups, physiological changes while riding the ergometer can be compared with established baselines to evaluate physical fitness.
Measure Work Exerted
- The bicycle ergometer can help riders improve their efficiency. Instruments attached to the bicycle ergometer's pedals measure the net amount of work exerted during a given period of time. A comparison of total work exerted versus energy output among different riders can determine which rider has the most efficient technique.
Monitor Physical Training Progress
- The bicycle ergometer can be used to monitor the progress of athletes training for physically demanding events or astronauts preparing for space travel. By taking daily or weekly measurements of heart rate, oxygen intake and other functions during a certain regimen, such as 50 pedals per minute, the rider can evaluate his or her progress. The ergometer can also be used to evaluate zero-g effects on the human cardiovascular system.
