Jump performance and thigh muscle cross-sectional area in young female rhythmic gymnasts

BACKGROUND: The relationship between sports injuries, health related quality of life (HRQoL) and parental instruction is still not clear so our aim was to determine sports injuries biosocial predictors in Portuguese youth. METHODS: Information about HRQoL, parental instruction and sports injuries was assessed via three questionnaires (KIDSCREEN-52, RAPIL II and LESADO) and filled by 651 subjects aged 10 to 18 years. Univariate analyses were used to verify significant differences between groups. Logistic, linear and multinomial regression analyses were used to determine significant biosocial predictors of injury, injury rate, injury type and body area injury location. RESULTS: Injury rate was higher in boys with lower scores in school environment dimension of KIDSCREEN-52 (P=.022) and in girls was higher in those with lower scores of moods and emotions dimension (P=.001) and higher scores of self-perception dimension (P<.001). Also in girls, upper limbs injuries were associated with higher scores of moods and emotions dimension and spine and torso with lower scores (P=.037). Lower limbs injuries were associated with lower father’s education and upper limbs (P=.046) and spine and torso injuries (P=.034) with higher father’s education. CONCLUSIONS: Sports injuries were related to several dimensions of KIDSCREEN-52 and parental instruction.
