TABLE 7.

Multiple linear regression model (R²_adj = 0.65, p < 0.001) for the prediction of soccer players’ individual number of headers from the observed cognitive and sensorimotor performance changes between re-test and post-test.

Parameter	ß	p
Δ Writing analysis SPress [N]	0.347	0.022*
Δ Writing analysis CFreq [Hz]	−0.488	0.002*
Δ Balance DT CoPDist [cm]	0.486	0.002*
Δ 2Back-Task accuracy [%]	0.351	0.023*

Outcomes were controlled for the number of previous head injuries, educational level, player age at baseline, and years of soccer experience.

*p < 0.05.
