Fig 1.
Accelerating and decelerating phases during an actual jump squat attempt.
The measurement was performed at the optimum power zone. From the take-off (when the velocity begins to decrease) to the final point of the upward movement (at “zero-velocity”) the athlete vertically jumps ≈ 20 cm.

Mean propulsive power (MPP), MPP load (kg), optimum MPP load expressed as percentage of body mass (MPPBM), relative MPP (MPP REL), mean propulsive velocity (MPV), and jump height performance in the elite individual/team sport athletes.
Fig 2.
Mean propulsive velocity (MPV) and relative mean propulsive power (MPP REL) of elite individual/team sport athletes.
The central, unbroken line represents the mean and the dashed lines represent the confidence interval (95%) of the MPV of all athletes. P T&F = power track & field (sprinters, jumpers, throwers, decathletes, and heptathletes); RB/AF = rugby and American football; Combat Sports = karate and taekwondo.
Fig 3.
Jump height and relative mean propulsive power (MPP REL) of elite individual/team sport athletes.
The central, unbroken line represents the mean and the dashed lines represent the confidence interval (95%) of the jump heights of all athletes. P T&F = power track & field (sprinters, jumpers, throwers, decathletes, and heptathletes); RB/AF = rugby and American football; Combat Sports = karate and taekwondo.
Fig 4.
Relation between mean propulsive power (MPP) and mean propulsive velocity (MPV).
The polynomial lines represent the MPP and the rectilinear lines represent the MPV. The presented values were obtained during actual testing attempts. Black symbols represent a power track and field athlete and the grey symbols represent an endurance runner. Independent of the power values, both athletes achieve the optimum power zone at 1 m·s−1.
