Table 1.

Selected parts of each movement to study hesitation. Athletes took different steps between movements due to their different levels of expertise. Therefore, in MOV2 and MOV3, the last step before jumping was considered the beginning of the selected part.

Movements	Video		Velocity Signal
	Start	End	Start	End
MOV1	Frame where athletes start bending.	Frame before athletes begin to rise, in which knees are at the maximum degree of bending.	Relative maximum before the sudden drop due to knee bending.	Absolute minimum in the same deflection.
MOV2	Last step before athletes jump over the second plinth.	Last frame before the first foot leaves the ground.	Relative maximum coincident with the athletes' last step before the jump over the second plinth.	Subsequent absolute minimum of deflection.
MOV3	Last step before jumping.	Last frame that precedes the athletes' jump.	Relative maximum coinciding with the athletes' last step.	Subsequent absolute minimum of deflection.
