Abstract

The tennis serve is closely related to the quality of the tennis match. However, the isokinetic parameters associated with the tennis serve are still unclear. The aim of this study was to investigate the relationships between ball velocity and isokinetic shoulder strength in tennis serve and to determine isokinetic strength parameters that can predict tennis serve velocity. A total of 13 elite male athletes (16.8 ± 1.5 years) voluntarily participated in the study. The athletes' shoulder internal-external rotation, extension-flexion and abduction-adduction strengths were measured with 5-5-15 repetitions at 60°/s, 180°/s, 240°/s angular velocities. Later, the athletes' 1st, 2nd, and average serve ball speeds were determined using a handheld radar gun. Significant correlations were found between ball speed and isokinetic tennis serve strength (r = 0.556-0.819; p < 0.05). The correlations between ball speed and isokinetic strength performance were higher at 180°/s and 240°/s angular velocities. Extension (240°/s; r = 0.819), flexion (180°/s; r = 0.755), abduction (240°/s; r = 0.733), adduction (240°/s; r = 0.684) and internal rotation (180°/s; r = 0.803) were highly correlated with ball velocity. These findings suggest that strength training to increase the ball speed of the tennis serve should be performed fast at high angular velocities and planning should focus on the strength of extension, flexion, abduction, adduction and internal rotation.

等动肩部力量是网球发球速度的决定因素吗？

网球发球与网球比赛的质量密切相关。然而，与网球发球相关的等动参数仍不清楚。本研究旨在探讨网球发球时球速与肩部等速力量之间的关系，并确定可预测网球发球速度的等速力量参数。共有 13 名精英男子运动员（16.8 ± 1.5 岁）自愿参加了研究。在60°/秒、180°/秒和240°/秒角速度下，以5-5-15次重复测量了运动员的肩部内旋-外旋、外展-屈伸和外展-内收力量。随后，使用手持雷达枪测定了运动员的第一、第二和平均发球球速。结果发现，球速与等速网球发球力量之间存在显著相关性（r = 0.556-0.819; p < 0.05）。在 180°/s 和 240°/s 角速度下，球速与等速力量表现之间的相关性更高。伸展（240°/s；r = 0.819）、屈曲（180°/s；r = 0.755）、外展（240°/s；r = 0.733）、内收（240°/s；r = 0.684）和内旋（180°/s；r = 0.803）与球速高度相关。这些研究结果表明，提高网球发球速度的力量训练应在高角速度下快速进行，并应重点规划伸展、屈曲、外展、内收和内旋的力量。

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.
