Explain Astrand Cycle Test?
This is a sub maximal test done on cycle ergo meter. In this test, comparatively lower wattages are set. For example, for males less than 35 years of age are given to exercise on 100-150 watts and for females between 100-125 watts. For older adults, the wattage is further declined. Whether to use upper limit or the lower limit depends upon the body weight and prior fitness level of the person. The person is asked to pedal at 60 rp in for 6 munities at chosen loading, taking pulse every minute. Your pulse rate should be steady state (130-160 beats per minute). If pulse is not in target range (above or below), after 2 minutes, adjust loading by 25 watts accordingly for remainder of the test. At the end of minute 6, pulse and resistance loading is recorded. VO2 max in L/min is then converted to ml/kg/min by multiplying it by 1000 and dividing by body weight (kg).
The advantage of this test is that it is simple to do, reasonably accurate and easy for ECG monitoring. However, the disadvantage of this test is that test is less accurate with advancing age.
