Abstract
Fundamental movement performance is the product of the interaction of many factors. According to the constraints model, the movement can be influenced by factors of individual constraints, environmental constraints, and task constraints, and there are probably close relationships between individual factors and performance of standing long jump (SLJ). The main purpose of this study was to investigate the performance of SLJ and its correlates among male children in later childhood. Seven selected individual factors, pattern of SLJ, leg strength, leg length, body mass index (BMI), and the flexibility of hip, knee, and ankle were examined its relationships with and predictors for SLJ’s performance. One hundred and twenty-one participants, whose mean age were 11.7 years (SD = 0.6 years), were measured for the seven individual factors, the SLJ performance, and SLJ pattern. Total body approach was used to analyze SLJ pattern. The inter-rater reliability was .85; the intra-rater reliability was .90. The Stepwise Regression analyses showed that: (1) SLJ’s performance was positively correlated with the level of SLJ (r = .79, p < .05), leg strength (r = .33, p < .05), the flexibility of hip (r = .34, p < .05), knee (r = .48, p < .05), and ankle(r = .22, p < .05), SLJ’s performance was negatively correlated with BMI (r = -.41, p < .05), and (2) SLJ’s pattern, the flexibility of hip, and knee accounted for 69% of the SLJ’s performance variance. Therefore, it was concluded that, among children in later childhood, (1) the factors of the level of SLJ, leg strength, BMI, the flexibility of hip, knee, and ankle were correlated with SLJ’s performance, and (2) SLJ’s pattern, the flexibility of hip and knee were the predictors of SLJ’s performance.
Key words: constraints model, later childhood, standing long
jump, movement patterns, individual factors.
