Table 6:

Significance (p-values) for pairwise comparisons of PAA, PLA and total impacts for across the entire sample

PAA
	PRE 1	PRE 2	POST 1	POST 2
PRE 2	0.562
PRE 3	0.294	0.690
POST 2			0.382
POST 3			0.224	0.835
PLA
	PRE 1	PRE 2	POST 1	POST 2
PRE 2	0.877
PRE 3	0.167	0.198
POST 2			0.100
POST 3			0.938	0.158
Total Impacts
	PRE 1	PRE 2	POST 1	POST 2
PRE 2	0.490
PRE 3	0.243	0.795
POST 2			0.698
POST 3			0.830	0.849

Note: PLA = peak linear acceleration, PAA = peak angular acceleration, PRE = 3 practice sessions without the guardian cap and POST = 3 practice sessions with the guardian cap.
