Which test is commonly used to assess lower-body power through staircase stepping?

• A. Margaria-Kalamen test
• B. vertical jump
• C. 1RM power clean
• D. 1RM bench press

Answer: (A)

Measuring lower-body power through a rapid stair climb is most commonly done with the Margaria-Kalamen test. In this test, an athlete sprints up a flight of stairs while the time to cover a defined number of steps is recorded. Power is estimated from the vertical distance climbed (the height moved) and the body mass, divided by the time to ascend, linking the effort of lifting the body's weight against gravity to the speed of the movement. This setup specifically captures how quickly the legs can generate force to produce explosive, vertical displacement in a stair-stepping pattern. While a vertical jump also reflects leg power, it measures jump height rather than stair-descending or stair-climbing speed; 1RM lifts like the power clean or bench press assess maximal strength or power in a different context and not the stair-stepping pattern described. Therefore, the Margaria-Kalamen test is the best fit for assessing lower-body power through staircase stepping.
