Mechanical energy compensation coefficients (MECs) of the ankle, knee, and Initial hip contact and the Peak knee flexion of front and right lunging (Mean ± SD) for concentric and eccentric energy transfers

Variable		Initial contact			Peak knee flexion
		Professional	Amateur	p-Value	Professional	Amateur	p-Value
		Mean ± SD			Mean ± SD
Ankle	MECC	0.42 ± 0.07	1.69 ± 0.16	< 0.001*	0.52 ± 0.08	0.44 ± 0.24	0.318
	MECE	0.88 ± 0.06	0.84 ± 0.08	0.302	0.79 ± 0.13	0.61 ± 0.13	< 0.007*
Knee	MECC	1.71 ± 0.57	0.29 ± 0.28	< 0.001*	0.03 ± 0.02	0.64 ± 0.16	< 0.001*
	MECE	1.81 ± 0.57	0.44 ± 0.32	< 0.001*	0.30 ± 0.06	2.04 ± 0.33	< 0.001*
Hip	MECC	1.48 ± 0.20	1.33 ± 0.27	0.198	1.46 ± 0.51	0.38 ± 0.23	< 0.001*
	MECE	2.46 ± 1.21	0.38 ± 0.10	< 0.001*	1.37 ± 0.10	0.32 ± 0.16	< 0.001*

Note: *statistically significant differences between the Professional and Amateur groups. **P-value < 0.05 is considered to be statistically significant; MEC always zero for no-transfer conditions
