For 1-Mile Walk Test, the VO2max was measured using a treadmill protocol which included running or walking at a speed that was self-selected, with a two and a half rise in grade every two minutes. Ability to estimate VO2max from the outcomes of maximal and submaximal exercises Introduction VO2max (maximal oxygen uptake) is actually considered as the best way of determining aerobic performance and fitness of cardio-pulmonary. It is believed that the best way of estimating maximum oxygen uptake is by directly measuring the uptake of oxygen during maximal exercise. However, this method is not an easy one due to the requirements of an all-inclusive medical check-up before the exercise and unrelenting supervision of the trial or test by a medical doctor with expertise in the treatment of the circulatory failure. Moreover, proper laboratory apparatus for directly measuring maximum oxygen uptake is quite costly and requires professionalism. Andersen, (1995) says that various methods have been devised to help in the prediction of VO2max from maximal or submaximal exercises. ...
se trials, such as from the ration between the HRrest and HRmax, or even from the self-reported predictor variables that do not involve exercise including the perceived functional ability of the participant to exercise, BMI, gender and habitual physical activity. According to Carey, et al (1995), in the past few years, despite the great technical development in the construction of the up to date or latest facilities for the measurement of the uptake of oxygen, we find that some novel methods of measuring VO2max have increasingly been designed and are regarded as very effective, especially in the researches on samples of large populations. However, these methods were usually applied in the field together with pre-selective researches focusing on the first determination of dispositions to the endurance sports. Witte, et al, (2001) say that nevertheless, there is not information that has been published about the estimation of VO2max from both the maximal and submaximal exercise trial on ski ergometer. This study aims at examining the accuracy of the prediction of the VO2max from maximal and submaximal exercise on three different methods namely; Multistage Fitness Test, 1-Mile Walk Test and Graded Exercise Test. Mitchell, (1997) claim that the MSFT (Multi-Stage Fitness Test), which is also known as the Beep Test or even Leger Test, is in the estimation of the VO2max of an athlete. The measurement of VO2mx is done in ml/kg/min. This is a very common and widely accepted in-season and pre-season fitness examination for athletes. The minimal space and facilities requirement has made it attractive for several coaches. Nonetheless, the interval runs, which are part of the exercise, seem to be very challenging. However, it offers a very good spread in the outcomes, dividing or ...Download file to see next pagesRead More
