^aIndicates effect size.

^bIndicates the high–initial impact-phase energy-absorption group was different from the low–initial impact-phase energy-absorption group (P < .05).

^cIndicates the high–initial impact-phase energy-absorption group was different from the moderate–initial impact-phase energy-absorption group (P < .05).
