Table 1.

Mean and standard deviation values for age, body mass, height, body mass index (BMI) and duration of practice according to occurrence of injury

Variable	Injury
	Presence (n = 104)	Absence (n = 418)
Age (years)	15.55 ± 1.47*	14.78 ± 1.69
Body mass (kg)	66.63 ± 13.36*	59.09 ± 11.58
Height (m)	1.74 ± 0.12*	1.67 ± 0.10
BMI (kg · m -2 )	21.73 ± 2.57*	20.88 ± 2.85
Duration of practice (years)	3.62 ± 1.66*	3.13 ± 1.67

Note: *Statistically significant difference in relation to absence of injury (p < 0.05). The Student’s t-test for independent samples was used to compare means in two groups for height. The Mann–Whitney test was used to compare medians in two groups for age, body mass, body mass index and duration of practice.
