Table 5:

Significance (p-values) for pairwise comparisons of PAA, PLA and total impacts for the 7 consistent players

PAA
	PRE 1	PRE 2	POST 1	POST 2
PRE 2	0.559
PRE 3	0.985	0.461
POST 2			0.927
POST 3			0.148	0.096
PLA
	PRE 1	PRE 2	POST 1	POST 2
PRE 2	0.387
PRE 3	0.638	0.582
POST 2			0.331
POST 3			0.074	0.395
Total Impacts
	PRE 1	PRE 2	POST 1	POST 2
PRE 2	1.000
PRE 3	0.904	0.876
POST 2			0.343
POST 3			0.616	0.313

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.
