Abstract:
This research aims to analyze the backhand short and flick serving pattern while racket contact shuttlecock while landed on excellent and good areas in Thai badminton players. 14 Thai national badminton players who be the mens double, womens double, and mixs double players were recruited. Each subject was then asked to perform 21 backhand short serves, and 21 flick services from backhand side, respectively. An infrared motion analysis system stemmed from 8 cameras and 1 video camera Qualisys Oqus 7+ (Qualisys, Sweden, 300Hz) was utilized to compile the kinematic determinants of the attendees during their services. To investigate corporeal kinematic and kinetic variables, Qualisys tract manager (QTM) software and Visual3D software (C-Motion, Inc., Rockville, MD, USA) were leveraged. The one-way analysis of variance with repeated measures (One-way anova with repeated measures) was leveraged to determine the difference between mean and standard deviation of kinematic and kinetic data. The results of this research showed the different at elbow angle, angular velocity of wrist, racket head velocity, racket angle with net, distance and time of forward swing phase, acceleration and velocity of shuttlecock while compared among excellent short service with flick service. Moreover, while compared among good short service with flick service showed the different at elbow angle, angular velocity of wrist, racket head velocity, racket angle with net, distance and time of forward swing phase, acceleration and velocity of shuttlecock for determining the level of significance at 0.05. On the other hands, no different while compared among excellent and good short service and flick service for determining the level of significance at 0.05, respectively. From the results can conclusion that elbow angle and angular velocity of wrist maybe the key indicator that influence on discipline of service, velocity and distance of shuttlecock travel that landed on different target area.
