Therefore, players need excellent joint range of motion (ROM), power, and agility (Tiwari et al., 2011 Wong et al., 2019). Players must repeat actions quickly with high speed and intensity. In addition, badminton players must react by moving rapidly with powerful jumps and agile footwork throughout a game. Performing a good lunge step is usually associated with high flexibility. The lunge step is one of the most frequently performed movements in badminton, accounting for approximately 15% of the total movements in a game (Kuntze et al., 2010 Mei et al., 2017). Athletes, coaches and athletic professionals may consider them when selecting effective warm-up practices to augment athletic performance.īadminton is a popular sport and one of the fastest racquet sports (Lees, 2003). Moreover, the addition of VFR to DS results in a large reduction of muscle stiffness, potentially reducing the risk of sports injury. Taken together, we suggest that practitioners consider DS as a first line of warm-up exercise to increase ROM, CMJ height, and agility in athletes. DS + VFR was not significantly superior to DS, except for muscle stiffness reduction. Results indicated that the protocols improved performance. Main outcome measures: The primary outcome was knee range of motion (ROM), and the secondary outcomes were muscle stiffness, lower limb power (countermovement jump ), and agility. The target muscle groups were the bilateral shoulder, anterior and posterior thigh, posterior calf, and lower back. Forty badminton players performed DS or DS + VFR as warm-up exercises on two occasions in a randomized order. This crossover study investigated the effects of DS or DS followed by VFR (DS + VFR) during warm-ups on flexibility, muscle stiffness, power, and agility of the lower limbs in badminton athletes. Its underlying concept is that it combines foam rolling techniques with local vibration to improve ROM and muscular activation concurrently. Recently, vibration foam rolling (VFR) has emerged. Dynamic stretching (DS) is performed to increase sports performance and is also used primarily for transiently increasing range of motion (ROM).
