Effects of eight-week plyometric training on jumping high and specific movement patterns in badminton players
(Auswirkungen eines achtwöchigen plyometrischen Trainings auf die Sprunghöhe und spezifische Bewegungsmuster von Badmintonspielern)
Introduction: Plyometric training is popular among individuals involved in dynamic sports. Plyometric exercises, such as jumping, hopping, skipping and bounding are executed with the goal of increasing dynamic muscular performance, especially jumping (Kannas et al., 2012; Markovic, 2007). Much less information is available on the effectiveness of plyometric training (PT) in badminton, where jumping high (e.g. forehand overhead jump-smash) is important for success. The aim of the study was to investigate the effects on jumping high, agility and power among male and female junior badminton players of an eight-week periodized PT program using high-impact bilateral plyometric exercises.
Methods: Starting and finishing with the biomechanical diagnostics of the squat jump (SJ), counter movement jump (CMJ), and drop jump (DJ) on force plates, kinematic analysis of forehand overhead smashes, anthropometric data as well as force data for pre- and posttest were analyzed. Before and after the biomechanical diagnostics, the players underwent an 8-week plyometric training (2 units per week) with a total of 2286 jumps. 8 male and 3 female junior badminton players (age: 16.0 ± 1.6 years, height: 175.5 ± 9.9 cm, mass: 69.3 ± 11.4 kg) were tested for their performance in jumping high and forehand overhead jump-smashes.
Results: Looking at the plyometric strength parameters and the floor reaction time of the squat jump (p<0.05; dz=0.8) and the drop jump (p<0.05; dz=1.1), the positive effect of the eight-week plyometric training in junior badminton players is significant. Consequently, this form of training is essential for the development of junior and top-level badminton players. Moreover, the study has shown that the contact of the overhead smash cannot be increased by improving plyometric strength training (p>0.05). Therefore, the focus must be on technical training for complex movements, such as the badminton smash.
Discussion: It is considered to be important to include short-term plyometric programs in in-season preparation in order to improve complex badminton-specific dynamic performance (smash-jumping). The results of this study can directly be applied to specific badminton training. Furthermore, this study provides information on the increase in physical performance in combination with a technical component. The findings can also be used for the prevention of injuries.
