Effect of a specialized injury prevention program on static balance, dynamic balance and kicking accuracy of young soccer players

Table 2 Means, standard deviations and analysis of variance comparing performance for kicking accuracy, static balance and dynamic balance

Variable	Experimental		Control		Cohen’s d
	Pre	Post	Pre	Post
kicking accuracy	2.69 ± 0.54	3.06 ± 0.72	2.5 ± 0.51	2.82 ± 0.38	0.11
Static balance - BESS	3.52 ± 0.78	3.35 ± 1.04	1.72 ± 0.66	2.94 ± 1.171	1.92
Dynamic balance - YBT-R	0.98 ± 0.07	1.03 ± 0.07	0.97 ± 0.06	1.00 ± 0.04	0.31
Dynamic balance - YBT-L	0.98 ± 0.08	1.04 ± 0.072	0.97 ± 0.06	1.01 ± 0.04	0.32

¹Significant interaction (F_1,18 = 21.05, P < 0.01);

²Significant improvement (t = 1.78, P = 0.05). BESS: Balance Error Scoring System; YBT-R: Y Balance Test Right leg; YBT-L: Y Balance Test Left leg.
