Margaria-Kalamen Anaerobic Power Test
Materials/Procedures
The materials used for the Margaria-Kalamen test are two timing foot plates, a timer to record the contact made with the first and second plate, and duck tape. The first foot plate is placed on the third step of the stair case, while the second foot plate is on the ninth step. The third step plate is connected to the “start” function in the timer, while the 12th step plate is connected to the “stop” function of the timer. When contact is made with the 3rd step, the timer should start while making contact with the 12th step should stop the timer. It is critical that the subject makes contact with the foot plates otherwise the timer would not start or it fails to stop thus resulting in a error. The subjects can perform any stepping strategies that they may feel is most comfortable to them or that may result in a better time such as skipping one, two, or three steps. A 10 to 15 minute warm up is required before performing the Margaria. The subjects will walk one full lap around the gym and another lap consisting of a slow jog. At one end of the court, the subjects will execute high knee jumps across the gym and return back to the starting position. For the final warm up, individuals will slowly jog up the stairs and walk down which is performed a couple times. The starting …show more content…
Work is calculated by force times the distance times the gravitational force (GRF). Force is given by the individual’s mass in kilograms multiplied by gravity acting downwards, which is -9.81 N/kg. In this case the GRF is defined as 6 steps converted into meters while each step is approximately 7 inches and 1 inch is 0.0254 meters. Absolute power output is calculated by work divided by 1.05, which is recorded in watts. Relative power output is defined as the absolute power output over the mass, which is measured in watts per
