Abstract

Purpose: This study examined the physical determinants of 60-m sprint and long jump (LJ) performance and differences between maturity groups in physical characteristics in young male track-and-field athletes.

Methods: Competition results, countermovement jump, isometric leg press, 10-5 repeated jump test, and 50-m sprint were collected over 3 seasons for 54 male athletes (age 13 [1] y; stature 160.0 [8.9] cm; body mass, 48.0 [9.8] kg; percentage predicted adult height 92.2% [5.5%]) grouped by maturity status: approaching- (n = 16), circa- (n = 19), and post-peak height velocity (PHV) (n = 19).

Results: There were significant between-group differences in 60 m, LJ, and all physical testing variables (P < .001, g = 0.88-5.44) when comparing the approaching- and circa-PHV groups with the post-PHV group. Significant differences were identified between the approaching- and circa-PHV groups in 40-m (P = .033, g = 0.89), 50-m (P = .024, g = 1.64), and 60-m (P < .001, g = 0.89) sprint times. Countermovement jump and 50-m sprint variables were consistently important for projection of 60 m and LJ performance across the valid multivariate models.

Conclusions: Large differences in performance across maturity groups highlight the importance of understanding athletes' maturity status to accurately interpret performance. Several physical performance variables were important for projecting competition 60 m and LJ performance.

不同成熟度的青少年男子田径运动员短跑和跳远成绩的物理决定因素。

目的：本研究探讨了决定年轻男子田径运动员 60 米短跑和跳远（LJ）成绩的体能因素，以及不同年龄组在体能特征上的差异：收集了 54 名男运动员（年龄 13 [1] 岁；身材 160.0 [8.9] 厘米；体重 48.0 [9.8] 千克；预测成人身高百分比 92.2% [5.5%]）三个赛季的比赛成绩、反身跳、等长压腿、10-5 重复跳测试和 50 米短跑成绩，并按成熟度分组：接近成熟度（n = 16）、大约成熟度（n = 19）和身高峰值后速度（PHV）（n = 19）：接近和大约身高峰值组与后身高峰值组相比，在 60 米、长距离跳高和所有体能测试变量方面存在明显的组间差异（P < .001，g = 0.88-5.44）。在 40 米（P = .033，g = 0.89）、50 米（P = .024，g = 1.64）和 60 米（P < .001，g = 0.89）短跑时间方面，接近和大约接近高血压组之间存在显著差异。在有效的多变量模型中，反身跳和 50 米短跑变量对 60 米和长距离跳远成绩的预测一直很重要：不同成熟度组别的成绩差异很大，这凸显了了解运动员成熟度对准确解释成绩的重要性。有几个体能变量对预测 60 米和长距离跳远的比赛成绩非常重要。

期刊介绍： Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach. Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
