Improving badmintion skills in beginners

Improving badminton skills

SPEED supported a research exercise conducted by students of the Sport Science Department of the University of Sabaragamuwa on utilizing video evidence to improve the badminton skills of beginners.

The main objective of this research was improving basic badminton skills (lob shot, high service and footwork) through video analysis. One subject was selected. Two video camcorders were used as well as the Kinovea videoanalyzing software. A total of 15 days at two hours a day were spent on the study. Physical tests were performed before commencement of training and throughout the training, the subject maintained correct hydration levels and went through an adequate warm up and warm down.

Results were collected using two methods. The first was by conducting pre & post tests. The other was to videograph the subject’s skills by using two cameras. For video analysis, a sport-analyzing software was used and angles important to badminton were shot. By using linear motion & angular motion formulas in the mechanics, when hip rotation is increased, the kinetic energy increases in high service. The most suitable racket contact point in the lob shot varies with the height of the player. In the lob shot, the vertical angle of the shoulder is inversely proportional to the force.

Although this method of improving skills is suitable for any player it is most useful for intermediate players. Hip rotation, vertical shoulder angle in overarm shots, hip angle for footwork and shuttle contact point in overarm and underarm shots are critical for badminton players and these points can be easily improved by this method.

High service improvement:

According to this analysis, his pre-training body rotation was 470. Post-training this had improved to 900 – a difference of 45cm – 60 cm. That was a significant improvement of the high service. Normally a high service is used in singles matches and the improvement allowed the subject to project the shuttle to the back of the court with minimal effort and conserve energy since a winner had to serve a minimum of 42 times in a game.

High service improvement

Lob shot:

The point of contact of the racket with the shuttle was in front of the body before training resulting in the subject being unable to impart optimal force upon the shuttle using mainly his forearm to impart power to the shuttle with his racket contact point angle being 400. However, after the training his shuttle contact point was right above the head. His arm was straight. His shuttle contact point angle was 310.

Lob shot improvement

Shuttle contact point improvement:

Before the training, his shoulder angle of the contact point of the shuttle was 290. After the training, his shoulder angle of contact point was 130.
