Table 1. Descriptive data on jumping heights. Values are means (±SDs).

		DL	NDL	Symmetry Index (%)
Jump Height (m)		.722 (.068)***	.678 (.066)	6.275 (4.796)
Running Velocity (m·s^–1)		7.925 (.492)	7.755 (.416)	2.106 (4.940)
Contact Time	CT (s)	.233 (.020) *	.238 (.023)	-2.355 (6.077)
	CT_des (s)	.054 (.011)	.055 (.012)	-3.042 (7.022)
	CT_asc (s)	.179 (.014)	.183 (.014)	-2.217 (6.081)

* and * * * indicate that difference between the dominant (DL) and non-dominant leg (NDL) is significant p < 0.05 and 0.001, respectively.

Running Velocity, maximal value of the running approach velocity. CT_des, Contact time from touchdown to minimal vertical displacement of the center of gravity (CG_zmin). CT_asc, Contact time from CG_zmin to takeoff.
