Peak resultant kinematics for all HAEs by drill classification

Drill Classification		Linear Acceleration (g)	Rotational Acceleration (rad/s²)	Rotational Velocity (rad/s)

(a) Minimal or no Player ^b,c (n = 53)	Mean	7.4	605	7.0
	95% CI	6.3–8.7	518–706	6.1–8.0
	50th %ile	7.0	486	6.7
	95th %ile	20.3	2678	18.2
(b) Multiple Player vs Player ^a,c (n = 2082)	Mean	9.6	690	8.0
	95% CI	9.2–9.97	649–735	7.6–8.4
	50th %ile	9.2	642	8.2
	95th %ile	25.2	1712	16.2
(c) Single Player vs Player ^c,b (n = 1102)	Mean	10.5	750	8.9
	95% CI	10.0–11.0	702–801	8.4–9.4
	50th %ile	9.8	706	9.0
	95th %ile	28.1	1736	17.6

^a-c Classifications that share the same superscript letter have peak kinematics that differ at p < 0.05.
