Assessment of The Validity of McArdle Step Test for Estimation Oxygen Uptake (Vo2max)

The purpose of this study is to assess the suitability of the McArdle step test for determine maximum oxygen uptake in male students. For this purpose we randomly selected thirty male students of Shiraz University, with mean age, height, and weight of 22.6 year, 166.4 cm, and 56.9kg, respectively. Vo2 max of each participant was determined by shuttle run test and also by applying McArdle test within an interval of seven days between the tests. The mean of Vo2 max subjects were 45.53 (ml/kg/min) in Shuttle run (20 m) test and 44.53 (ml/kg/min) in McArdle step test. Also, the results show that Exhibited significant statistical correlation (r=0.71, p < 0.001) between the two tests. The result suggest that McArdle step test can be applied in the studied population to produce a good estimation of maximum oxygen uptake, specially in the field where large numbers of participants are to be evaluated without a well equipped laboratory.
