Abstract

Purpose: To investigate the effects of an eccentric hamstring strength training program (EHT) on sprint performance (10-, 20-, and 30-m sprint times) and change of direction speed (4 × 5-m shuttle run and T-Half test) in male European handball athletes at 2 maturity statuses (prepeak and postpeak height velocity [PHV]).

Methods: Forty-five participants (12.68 [1.58] y) were divided into pre-PHV and post-PHV and randomly allocated to a control or intervention group, which performed a guided 2 day per week 6-week EHT of 5 exercises. A mixed-model (within- and between-factor) analysis of variance was conducted.

Results: A significant effect (P < .05) of the interaction time × maturity × training was observed in the T-Half, 10, and 30 m tests. Both intervention groups significantly improved in all the tests, except in the 20 m sprint and the post-PHV in the 10 m sprint. Improvements ranged between 0.93% and 5.74% (effect size: 0.07-0.79). Both control groups yielded no improvements in almost all the tests. The improvements of both groups undergoing the intervention (pre-PHV and post-PHV) were not significantly different (only a tendency in the 10 m sprint).

Conclusion: An EHT program combined with European-handball training improve change of direction and sprint performance in pre-PHV and post-PHV male players. Professionals training European handball and similar team-sport athletes should consider including EHT regardless of athlete's maturity.

不同成熟状态运动员偏心腿筋训练对速度的提高。
目的:探讨偏心腿筋力量训练方案(EHT)对欧洲男子手球运动员在两种成熟状态(峰前和峰后高度速度[PHV])下冲刺表现(10米、20米和30米冲刺时间)和方向速度变化(4 × 5米穿梭跑和T-Half测试)的影响。方法:45名参与者(12.68 [1.58]y)分为phv前组和phv后组,随机分为对照组和干预组,在指导下每周2天进行为期6周的EHT,共5项运动。进行了混合模型(因子内和因子间)方差分析。结果:在T-Half、10和30 m测试中观察到交互时间×成熟度×训练的显著影响(P < 0.05)。除20米短跑和10米短跑后phv外,两个干预组在所有测试中均有显著改善。改善范围在0.93%至5.74%之间(效应量:0.07-0.79)。两个控制组在几乎所有的测试中都没有任何改善。两组接受干预(phv前和phv后)的改善无显著差异(仅在10米短跑中有趋势)。结论:EHT与欧式手球训练相结合,提高了男子运动员phv前后的方向变化和冲刺性能。专业人士训练欧洲手球和类似的团体运动运动员应该考虑包括EHT,无论运动员的成熟度如何。

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.
