However, such improvement was blunted by repetitive soccer headings in the heading group (pre, 43.6 ± 7.8 sec; 0 hr-post, 42.7 ± 7.9 sec; 2 h-post, 42.6 ± 7.8 sec; 24 h-post, 40.7 ± 7.3 sec), as illustrated by significant time × group interactions at 0 hr (p = 0.012) and 2 hr (p = 0.002) post-heading/kicking time points in the mixed-effect regression model.Conclusions Our data suggest that the neural circuit encompassing the brain and oculomotor system has tremendous abilities to adapt and improve its function if administered repeatedly, but subconcussive head impacts induced by soccer heading can transiently impair neuro-ophthalmologic function and its adaptive property.
