Ruan, M. (2005). The power output of drop jump is greater with approach run. Medicine and Science in Sports and Exercise, 37(5), Supplement abstract 2024.

College males (N = 12) performed a drop jump from 15, 30, 45, and 60 cm with a standing, and one, two, and three approach steps.

A drop height of 30 cm produced the highest combined power output with 60 cm being worse than 15 cm. When steps were introduced, the greater the number of steps, the greater was the power. The approach steps heightened the contribution of the knee to total power.

Implication. A drop jump with an approach produces more power than a standing jump. It trains explosiveness more effectively.
