“…Values generally agreed with the past works that were done for motion capture of badminton racket smash stroke, as seen in [110,111]. Literatures have shown that top players are capable of using the elastic deflection of badminton racket to achieve a higher tip speed [112][113][114]. While it might be critical for racket dynamics, this experiment was only for observing an estimate to develop a launcher.…”

“…Badminton rackets are composed of a rigid handle and a flexible shaft. The proximal-distal sequence contributes by increasing racket velocity to produce a powerful stroke, that allows the maximization of momentum transfer at impact, including racket velocity [17]. Compared with other racket sports, badminton rackets are relatively flexible [18].…”

Aim. Forearm extension and radio-ulnar pronation are two common components of the final movement during each badminton smash stroke. By coordinating the forearm to produce both extension and pronation at the same time, racket head velocity can be increased. Thus, this study examined maximal velocity and racket deflection during both movements in regard with skill level. Materials and methods. Twenty-two players (8 experts and 14 novices) participated in this study. Wrist, handle and racket head velocity were recorded using high speed cameras (Vicon V8i at a frequency of 250 Hz). Results. The racket head velocity with radio-ulnar pronation was 16 % higher than with forearm extension. This higher velocity resulted from an 8 % higher acceleration and a 70 % higher maximal angular velocity of the end points of the forearm segments during radio-ulnar pronation. In each movement, experts’ maximal velocity was higher than that of novices (p < .001).The maximal velocity of the racket for novices was obtained with elbow extension (20.9 ± 4.8 m/s), with a gain of 47 %, whereas for experts, it was obtained with radio-ulnar pronation (33.9 ± 5.8 m/s), with a gain of 53 %. Conclusion. The difference between the best velocities in both samples is 39 %, obtained respectively by radio-ulnar pronation for experts and an elbow extension for novices. Forearm extension and radio-ulnar pronation acceleration on the handle led to an increase in racket head velocity.

Modulus of elasticity (MOE) is one of the important indexes to evaluate the performance of badminton string. In this work, a series of tensile testing were performed to explore the changes in MOE at different temperature, humidity, and tensile rate. Based on the experimental results, an MOE model for badminton string was developed by using response surface methodology. Meanwhile, the significant contribution of each variable and two-factor interactions on MOE were investigated by analysis of variance. The special aim of this work was to determine the optimal processing parameters for maximum MOE for the higher performance of badminton string, and those processing parameters are temperature of 10.7°C, humidity of 0.19%, and tensile rate of 59.98 mm/min, which were propped to be adopted for the actual use of badminton string.
