of this alteration is to more fully stress both the alactic and lactic anaerobic energy systems, which are the main source of energy for the first two minutes of exercise. Another alteration that has been made is the repetition of Wingate tests. In current literature, this test has been repeated four, five, or even six times in one testing session. Repeating the Wingate test during training sessions can increase aerobic power and capacity, as well as maximal aerobic capacity. The last common alteration is the workload during the test. The original Wingate test used a load of 0.075 kp per kg bodyweight of the subject. As these were young subjects, some suggest that adult subjects should use higher workloads, and several different loads have been used. Katch et al. used workloads of 0.053, 0.067, and 0.080 kp per kg bodyweight, while other researchers have increased the workload even higher, to 0.098 kp per kg bodyweight. The advantage of increasing the workload can show an increased, and therefore more representative, value for peak power in collegiate athletes. The workload can be altered, but a standard Wingate test still uses the original workload. Common Testing Procedure Before the subject starts the Wingate test, they typically perform a low-resistance warm-up for at least five minutes to help minimize the risk of injury. During the warm-up the subject generally completes two or three 15 second “sprints” to make sure they are used to the fast movement before the test begins. On completing the warm-up the subject should rest for one minute, after which the test begins. The subject gets a five-second countdown to the beginning of the test, during which time they pedal as fast as they can. On the start of the test, the workload drops instantly (within three seconds if using a mechanical ergometer) and the subject continues to pedal quickly for 30 seconds. An ergometer with an electromagnetic brake generally collects and displays data through a computer. With a mechanical ergometer, the researcher must count and record the number of revolutions pedaled for every five second interval during the test, and then determine power data. On test completion, the subject should pedal against low resistance in a cool-down phase. The Wingate test can be completed on several types of bicycle ergometers, which can be controlled with either mechanical or electromagnetic brakes. If an ergometer with an electromagnetic braking system is used,
