- Repco front access cycle ergometer (which uses air resistance to modify resistance)
- Heart rate monitor
- Work monitor unit (optional, some bikes have a workload dial attached to the cycle)
- Stop watch
- Scales to determine the body weight of the athlete prior to the test
How to conduct The Tri-Level Aerobic Test?
- The athlete is weighed
- The athlete’s 75% MHR is determined – if unknown calculate MHR as 220-age
- The athlete pedals in one minute increments of 25 Watts (starting at 25 Watts) until their heart rate reaches 75% of their predicted maximum heart rate.
- The athlete continues pedalling until the end of the minute period during which the target heart rate is achieved.
- The workload at which the 75% predicted heart rate is achieved is recorded
Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.
The athlete’s Aerobic Index is determined by dividing the workload at which the 75% predicted heart rate is achieved by the athlete’s body weight.
This test is suitable for sprint and endurance athletes and players of endurance sports (eg football, rugby) but not for individuals where the test would be contraindicated.
Reliability would depend upon how strict the test is conducted and the individual’s level of motivation to perform the test.
There are no published tables to relate results to potential performance in competition.
