he table presented below summarizes the data collected and computed from the analysis of GRF graphs for both countermovement jumps with arm swing and concentric-only jumps for two participants. The calculations were performed using both the Time of Flight method and the Impulse-Momentum relationship.

Measurement	Athlete 1 - CM with Arms	Athlete 1 - Concentric Only	Athlete 2 - CM with Arms	Athlete 2 - Concentric Only
Time of flight (s)	0.54	0.50	0.57	0 .46
Peak Force	1,700 n	1,770 n	2,020 n	2,000 n
