THE IMPORTANCE OF THE PERFORMANCE MODEL

In this article we will mainly talk about the performance model by analysing it from a physical and conditional point of view, but we know how a physical trainer specialized in a sport, over time, also learns to know the technical and tactical performance model of the sport in which he trains.

It is fundamental when the sport in question becomes competitive and with performance objectives and results. The training of these factors that make up the reference model is studied and investigated in all its forms and with every useful tool in order to improve performance in training and on the field during competition.

Starting from this point, it is essential to study the competition and the athletes that comprise it, through sessions of video analysis of the techniques of shots used, study and analysis of the movements on the field, working angles between body segments, overall duration of the game actions, distances travelled, number of accelerations and decelerations, evaluation of recovery times, physiological parameters, visual and perceptual analysis and training, and mental aspects related to performance and management of emotions.

Quickly summarizing these concepts, it is easy to understand how tennis is a sport that includes many pieces for the puzzle to be assembled. Getting more into the matter, and limiting ourselves to the physical part, we discover that tennis is an intermittent or an aerobic-anaerobic alternating sport, and that is often played for a long time.

A tennis player’s efforts require anaerobic activities, without underestimating the aerobic part, with high-intensity repetitive efforts. The short duration of the game actions and the fact that the tennis player often expresses a high power in the shots suggests that the contribution of the anaerobic alactacid system to the production of energy is rather relevant.

On the basis of the values ​​found in the studies present in the literature, a performance model is outlined that identifies tennis, from a metabolic point of view, as a sport characterized by repeated and rapid increases in energy demand that do not allow the oxidative system to satisfy these applications.

CONCLUSION Optimal performance of the overhead throwing task requires precise mechanics that involve co-ordinated kinetic and kinematic chains to develop, transfer and regulate the forces the body needs to withstand the inherent demands of the task and to allow optimal performance.

These chains have been evaluated and the basic components, called nodes, have been identified. Impaired performance and/or injury can be associated with alterations in the kinetic chain mechanics. The pathomechanics can occur at multiple locations throughout the kinetic chain.

They must be evaluated and treated as part of the overall problem. Observational analysis of the mechanics and pathomechanics using the node analysis method can be useful in highlighting areas of alteration that can be evaluated for anatomic injury or altered physiology.

The comprehensive kinetic chain exam can evaluate sites of kinetic chain breakage and a detailed shoulder exam can assess joint internal derangement of altered physiology that may contribute to the pathomechanics.
