10 & 30-second Tri-level anaerobic Tests
The Tri-Level fitness testing battery involve a 10 second, 30 second and aerobic sub-maximal cycle tests. The first two, the anaerobic fitness test components, are described here.
- equipment required: Repco front access cycle ergometer (which uses air resistance to modify workload), work monitor unit, stopwatch, weight scales to record subjects mass.
- procedure: The subject is instructed to pedal as fast as possible for 10 or 30 seconds. The feet must the firmly strapped onto the pedal to enable maximal power output. Strong verbal encouragement will help the subject achieve their maximal score. For the 10 second test, you may want to give the athlete two attempts, with five minutes break between, and record the best effort. Latest model recording units can record power and work output every second, with older units work output can be recorded manually at selected time intervals.
- scoring: The measurements that can be gained from the work monitor unit are total work (Alactic Work Index) and peak power (Alactic Power Index), and for the 30 second test (Lactic Work Index) a fatigue index can be calculated from the decline in power throughout the test. Peak power and total work scores can be divided by body weight for relative scores, and norm tables are available for these tests.
