The aim of the study was to determine canonic relations between the set of basic motor variables and the set of athletic variables assessing the abilities of sprint, throw and long-distance run adjusted for children aged seven years. Study sample consisted of 635 first-graders from Split elementary schools, divided into groups of 325 male and 310 female subjects. The set of nine variables of the basic motor space and three variables of situation motoricity in athletics were applied at the beginning and at the end of the academic year. Association between the sets of variables was determined by canonic correlation analysis. In male subjects, association between the sets of variables revealed a predominant effect of explosive strength on the sprint and throw ability on initial measurement. On final measurement, association in the first pair of canonic dimensions was underlain by the favorable impact of all strength factors with a predominance of explosive strength, which was accompanied by the development of flexibility and coordination, influencing performance in sprint and throwing; the second canonic variable was bipolar, differentiating aerobic endurance ability determined by above-average flexibility, frequency of lower extremity movements and static strength, and throwing ability determined by above-average equilibrium, explosive strength, coordination and repetitive strength. In female subjects, on initial measurement association in the first pair of canonic dimensions was mostly determined by the effect of explosive strength, repetitive strength of the trunk and movement frequency on general ability in athletics defined by the abilities of sprint, throw and long-distance run. Association in the second pair of canonic dimensions was determined by the impact of explosive strength and flexibility on sprint performance on the one hand, and by the effect of movement frequency and repetitive strength of the trunk on long-distance run performance on the other hand. In female subjects, final measurement yielded only one significant canonic correlation underlain by the impact of all strength factors, frequency of lower extremity movements and flexibility on performance in the athletic events of sprint and throw. Relations between the sets of variables are also discussed according to sex.
本研究的目的是确定针对7岁儿童调整后的基本运动变量集与评估短跑、投掷和长跑能力的运动变量集之间的典型关系。研究样本包括来自斯普利特小学的635名一年级学生，分为325名男性和310名女性两组。在学年开始和结束时应用了基本运动空间的九个变量集和田径运动情境运动性的三个变量。通过典型相关分析确定变量集之间的关联。在男性受试者中，变量集之间的关联在初始测量时显示出爆发力对短跑和投掷能力的主要影响。在最终测量时，第一对典型维度中的关联是由所有力量因素的有利影响所支撑，其中爆发力占主导地位，同时伴随着柔韧性和协调性的发展，影响短跑和投掷表现；第二个典型变量是双极的，区分了由高于平均水平的柔韧性、下肢运动频率和静态力量决定的有氧耐力能力，以及由高于平均水平的平衡、爆发力、协调性和重复力量决定的投掷能力。在女性受试者中，在初始测量时，第一对典型维度中的关联主要由爆发力、躯干重复力量和运动频率对由短跑、投掷和长跑能力定义的田径综合能力的影响所决定。第二对典型维度中的关联一方面由爆发力和柔韧性对短跑表现的影响所决定，另一方面由运动频率和躯干重复力量对长跑表现的影响所决定。在女性受试者中，最终测量仅产生了一个显著的典型相关，其由所有力量因素、下肢运动频率和柔韧性对短跑和投掷体育项目表现的影响所支撑。还根据性别讨论了变量集之间的关系。
