Astrand-Rhythmic Testing
Introduction
Astrand-Rhythmic test is a test conducted to find the maximal oxygen uptake also known as the VO2max of an athlete. It can be used on elite athletes and individual athletes. This test helps to measure the ability to perform. The test can be done on an ergometer or on a treadmill. The measurement of the VO2max is the best measure of the cardiorespiratory system. This is important information as it indicates the body’s ability to transport and consume oxygen. There are two ways to measure the VO2max; it is the direct measurement or indirect estimation. Direct measurement is the usually done with exercise test and a selected protocol and the indirect estimation. One of the most well-known tests is the Astrand Bike Test. These tests are called submaximal tests and are based on the relationship between the heart rate and maximal oxygen intake. Basically we are focusing on the Astrand 6 minutes rhythmic test which is an indirect estimation of the aVO2max.These test was created by Astrand in 1956.
Steps
1. Determine the predicted HRmax using the standard regression equation: 220 – age.
Next calculate 60% and 70% of the subject’s predicted HRmax
2. Work in a group of three. To measure heart rate, and recorded data.
3. Warm up about 10 minutes before the test.
4. Adjust the seat height on the cycle ergometer so that the knees are almost fully extended when the pedal are at the lowest point.
5. Start on the assistance command “GO”.
6. Adjust the work load to 100w and remain at the constant 60rpm for 6 minutes.
7. Assistance would record the heartbeat for every last 15 seconds of each minute.
8. After 6 minutes take the final work rate wattage.
9. Recorded the data onto the brianmac.com astrand 6 minute cycle test for final result of VO2max.
