Abstract

This study compares the effects of the FIFA 11+ Kids program on lower limb isometric torque among young soccer athletes. Sixty-six male soccer athletes (aged 6-14 years) were allocated for convenience into three groups of different ages: G1 = 12-14 years, G2 = 9-11 years, and G3 = 6-8 years, on whom muscle assessments of isometric knee flexor and extensor torque and of isometric hip abductor and adductor torque were conducted before and after 8 weeks of the intervention. There was an increase in knee extensor torque (p < 0.001) in G1 and G2 and in knee flexor torque in G1 and G3 (p < 0.05) after the intervention, as well as an increase in hip abductor torque in G3 (p = 0.012). Further observations include an increase in hip adductor torque among all groups (p < 0.05) and in time-to-peak knee extensor torque in G1 (p = 0.005), as well as a decrease in time-to-peak knee extensor and hip adductor torque in G3 (p < 0.05) and in time-to-peak knee flexor torque in G2 (p = 0.022). As such, the FIFA 11+Kids program may produce a positive effect on knee extensor/flexor torque and hip abductor/adductor torque in young soccer athletes of different age groups, with an even greater effect when applied early (6-8 years).

国际足联11+儿童项目对不同年龄组足球运动员髋关节和膝关节肌肉扭矩的影响:一项前瞻性准实验研究。
本研究比较了FIFA 11+ Kids项目对青少年足球运动员下肢等距扭矩的影响。为方便起见,将66名6-14岁的男性足球运动员分为3组:G1 = 12-14岁,G2 = 9-11岁,G3 = 6-8岁,在干预8周前后分别对他们进行膝关节屈伸肌等距扭矩和髋关节外展肌、内收肌等距扭矩的肌肉评估。干预后,G1、G2组膝关节伸肌扭矩增加(p < 0.001), G1、G3组膝关节屈肌扭矩增加(p < 0.05), G3组髋关节外展肌扭矩增加(p = 0.012)。进一步观察发现,各组髋关节内收肌扭矩增加(p < 0.05), G1组膝关节伸肌扭矩峰值时间增加(p = 0.005), G3组膝关节伸肌扭矩和髋关节内收肌扭矩峰值时间减少(p < 0.05), G2组膝关节屈肌扭矩峰值时间减少(p = 0.022)。因此,国际足联11+儿童项目可能对不同年龄组的年轻足球运动员的膝关节伸/屈肌扭矩和髋关节外展/内收扭矩产生积极影响,早期应用(6-8岁)效果更大。

期刊介绍: Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
