Abstract

Purpose: The primary purpose of this study was to examine the effects of head impacts on postural control in NCAA Division I football athletes. An alpha level of 0.05 was set a priori.

Methods: Thirty-one Division I athletes (15 football and 16 non-contact) over the course of one fall season participated in this study. Each participant completed a series of quiet stance trials (three of single leg for 20 seconds; one of double leg for 120 seconds) on a force platform (1000Hz , AMTI model OR-6, Watertown, MA) within two week prior to and following a single fall season. Approximate Entropy (ApEn) in the anteroposterior (AP) and mediolateral (ML) directions were calculated during quiet stance.

Results: ApEn double leg ML showed a significant difference for time [F (1,26) = 4.536, p = .043, η = .149) and group [F (1,26) = 7.596, p = .011, η = .982]. Post-season testing (p = .005, η = .264) was significantly different between groups (p = .005, η = .264). ApEn left foot AP showed significant difference for time [F (1,26) = 11.808, p = 0.002, η = .312).

Conclusions: Over the course of a season subconcussive blows appear to not influence the postural control system. However, due to potential learning effects of an athletic season, athletes demonstrated improved postural control.
