Recreational tennis players tend to have higher incidence of tennis elbow, and this has been hypothesised to be related to one-handed backhand technique and off-centre ball impacts on the racket face. This study aimed to investigate for a range of participants the effect of off-longitudinal axis...

On the back side of the shoulder blade, at about two-thirds of its height, a bony ridge calledthe shoulder blade spineruns diagonally upwards toward the lateral angle and ends as a bony hook–the acromion–, which makes a bony roof of the shoulder joint. The part of the shoulder blade ...
As a consequence off-centre impacts below the longitudinal axis of the racket may be a substantial contributing factor for tennis elbow injuries due to forced wrist flexion and eccentric contraction of the wrist extensors.doi:10.1016/j.proeng.2010.04.179Mark King...
Origin of the long head: Supraglenoid tubercle (lateral angle) of the scapula Origin of the short head: Coracoid process of the scapula Insertion: Tuberosity of the radius (the thinner bone in the forearm) Function: Flexes the arm in the shoulder and elbow, supinates the forearm (which re...
The hitting position and velocity control for table tennis robots have been investigated widely in the literature. However, most of the studies conducted do not consider the opponent’s hitting behaviors, which may reduce hitting accuracy. This paper proposes a new table tennis robot framework that...
