RESUMO

Motor coordination and physical fitness are multidimensional concepts which cannot be reduced to a single variable. This study evaluated multivariate relationships among morphology, physical fitness and motor coordination in 74 pre-pubertal girls 8.0-8.9 years of age. Data included body dimensions, eight fitness items and four motor coordination tasks (KTK battery). Maturity status was estimated as percentage of predicted mature stature attained at the time of observation. Canonical correlation analysis was used to examine the relationships between multivariate domains. Significant pairs of linear functions between indicators of morphology and fitness (rc = 0.778, Wilks' Lambda = 0.175), and between fitness and motor coordination (rc = 0.765, Wilks' Lambda = 0.289) were identified. Girls who were lighter and had a lower waist-to-stature ratio and % fat mass attained better scores in the endurance run, sit-ups and standing long jump tests, but poorer performances in hand grip strength and 2-kg ball throw. Better fitness test scores were also associated with better motor coordination scores. Relationships between body size and estimated fatness with motor fitness suggested an inverse relationship that was particularly evident in performance items that required the displacement of the body through space, while motor coordination was more closely related with fitness than with somatic variables.

RESUMO

OBJECTIVES: Three questions were addressed: (1) Do female gymnasts have adolescent growth spurts in height, sitting height, and leg length? (2) Are the sequence and magnitude of spurts comparable with female adolescent non-athletes? (3) How do the data compare with other female gymnasts and with short girls? STUDY DESIGN: Height and sitting height were measured annually on 15 Belgian gymnasts from 8.7 +/- 1.5 to 15.5 +/- 1.5 years. The gymnasts trained, on average, approximately 15 h/wk. Leg length was estimated as height minus sitting height. The Preece-Baines Model I was fitted to individual growth records to estimate ages at peak velocity and peak velocities for the three dimensions. Age at menarche and skeletal age were also assessed. RESULTS: Gymnasts have clearly defined adolescent spurts in height, estimated leg length, and sitting height that occur approximately 1 year later and are slightly less intense than in nonathletic adolescent girls. Age at menarche and skeletal age are consistent with later somatic maturation. The pattern of adolescent growth and maturation is similar to that of other gymnasts, short normal late-maturing girls, and late-maturing girls with short parents. CONCLUSIONS: The results emphasize a primary role for constitutional factors in the selection process of female gymnasts at relatively young ages.
