VO2 max tests measure the maximum amount of oxygen an athlete can use during intense physical activity. The most common version involves running on a treadmill or cycling while connected to a mask that measures oxygen intake. The Balke test is a simpler version that estimates VO2 max by having the runner run as hard and fast as possible for fifteen minutes. Progress is measured by the distance covered during the workout.
VO2 max tests. They are used to determine the maximum amount of oxygen an athlete’s body can use during sustained, intense physical activity. Athletes strive to increase their VO2 max performance to improve stamina and stamina, and to determine how much improvement the athlete needs, VO2 max tests are used. While VO2 max tests can vary from sport to sport, the general concept is the same: measure the individual’s heart rate, increase the heart rate to the most optimal training rate, maintain the exercise for a set period of time and measure how much oxygen is being used
The most common version of VO2 max testing involves an athlete running on a treadmill or riding a bike. The athlete is connected to a mask that measures oxygen intake by collecting expired carbon dioxide in a bag or container for the duration of the test. The athlete must be in fairly good shape to take the test, as it is rigorous and causes the athlete to perform above the normal peak of the test. While the athlete is running or cycling, a coach will be prepared to schedule the test and increase the training intensity from moderate to maximum. At the end of the test, a special tool is used to measure the amount of oxygen used during the peak of the exercise.
Since this version of VO2 max testing can be expensive due to the equipment and labor involved, there is a simpler test that can only help estimate VO2 max. The Balke test was developed by Bruno Balke with the intention of helping runners determine their own VO2 max. The test is usually done outdoors on a windless day, but it can also be done indoors on a treadmill. The runner will run at a constant speed, as hard and fast as possible, for fifteen minutes. Usually a trainer is on standby to make sure the runner maintains a hard and fast pace. The coach will also note the distance the runner has covered during those fifteen minutes.
Once the test is complete, a mathematical equation is used to determine the runner’s VO2 max. The idea is that the runner’s VO2 max will increase in successive testing periods, as the runner trains to increase VO2 max. Progress is determined by measuring the distance covered during the fifteen minute workout. Generally speaking, if the runner covers more distance during the race, VO2 max is improving. The coach uses the mathematical equation to support this hypothesis, although this test can only give an estimate of how much the runner is actually improving.
