BIOMECHANIK TENNIS PDF

Anzumerken ist, dass die biomechanischen Prinzipien nicht zur Technikentwicklung, sondern nur zur Technikverbesserung. Das Prinzip des optimalen Beschleunigungsweges geht davon aus, dass bei dem Ziel einer hohen Endgeschwindigkeit der Beschleunigungsweg optimal lang verlaufen muss. Je nach Bewegungsziel kann eine zeitliche Optimierung der Einzelbewegungen wichtiger sein als eine Phasenweise Einsetzung der Einzelbewegungen. Dies kann ebenso gut genau umgekehrt der Fall sein. Das Prinzip der Gegenwirkung bezieht sich auf das dritte Newtonsche Axiom Actio gleich Reactio und besagt, dass zu jeder Bewegung eine Gegenbewegung entsteht. Das Gleichgewicht des Menschen ist beispielsweise ein Zusammenspiel von Bewegungen und Gegenbewegungen.

This article has been cited by other articles in PMC. Abstract Success in tennis requires a mix of player talent, good coaching, appropriate equipment, and an understanding of those aspects of sport science pertinent to the game.

This paper outlines the role that biomechanics plays in player development from sport science and sport medicine perspectives. Biomechanics is a key area in player development because all strokes have a fundamental mechanical structure and sports injuries primarily have a mechanical cause. Keywords: biomechanics, loading, stroke production, tennis Success in tennis is greatly affected by the technique a player uses and biomechanics plays an integral role in stroke production.

All strokes have a fundamental mechanical structure, and sports injuries primarily have a mechanical cause. An understanding of biomechanics from a sports medicine perspective is also important if player development is to occur with minimal risk of injury. The examples given in the following sections are intended to reflect general directions rather than provide a comprehensive review of the literature. More detailed reviews can be found in the ITF publication Biomechanics of advanced tennis, 2 and the books From breakpoint to advantage, 3 The physics and technology of tennis 4 and Biomechanical principles of tennis technique: using science to improve your strokes.

Firstly, biomechanics from a general perspective will be followed by the role it plays in stroke production. Sports medicine, as it plays a role in the development of stroke production, is then discussed from a biomechanical perspective. General theory of biomechanics Biomechanics theory provides coaches, players, and sport science support staff with a general framework for the development of stroke production. I will discuss a number of the general principles that guide this development.

This is also supported by the fact that the concentric action begins with the appropriate muscles under higher tension than would be created if they were to contract purely concentrically from a resting state.

Groundstrokes: Rotation of the shoulders greater than the hips creating a separation angle and the positioning of the upper limb relative to the trunk during the backswing phase of these strokes, place appropriate muscles on stretch. The key to the recovery of the elastic energy is the timing between the stretch and shorten phases of the motion. The benefit of this stored energy is reduced if a delay occurs between these phases of the movement. In tennis it is therefore essential that only a short pause occurs between the backswing and forwardswing phases of stroke production or at maximum knee flexion during the serve.

In strokes where power is required such as the service and groundstrokes , a number of body segments must be coordinated in such a way that a high racquet speed is generated at impact.

Where precision is needed, the number of segments is reduced and segments operate more as a unit such as the volley at the net , although the drive volley now challenges this general principle.
