Kinetic and Electromyography Characteristics Affecting the Performance of the Backhand with One Hand as a basis for design qualitative exercises in Tennis
This study aims to identify some biomechanical and Electromyography characteristics affecting the performance of one-handed backhand strokes (flat - top spin) as a basis for design qualitative exercises in tennis. Researchers utilized the descriptive method involving a device to measure the muscles and analysis Electromyography employing video imaging and analysis of motor skill search using three-dimensional kinetic analysis software. This study was applied on a single IFT-registered Egyptian national team player. The results of the current study indicate that the highest momentum have emerged through the trunk and upper arm in order to produce strong backhand.
The importance of trunk work as it increases force distance transferred to the arm and the stability of the elbow joint and forearm is maintained by the contraction of the biceps and triceps.
The linear momentum of the trunk is more pronounced leftward, and upward trunk movements are essential for generating the necessary linear momentum of the racquet. Moreover, stabilization of the trunk is also considered to be very effective for the sequential transfer of high force and energy through the trunk work. The muscle activity producing movement is the (Deltoid posterior part), and in the muscles against is the (Erector spine muscle).
