Jurnal Pendidikan Jasmani dan Olahraga, 2021
The purpose of this study was to analyze the joint motion kinetics of the shoulders, elbows, and wrists between experienced player (skilled player) group and unskilled player group when performing overhead standing smash in badminton game. The samples involved were 26 samples. The samples included 13 male badminton players joining Student Activity Unit who had achieved many achievements and had a high skill (skilled), while the other 13 samples were unskilled players, involving students who had just studied under one year. The mean of participants’ age was 19.4 ± 1.6 years, height was 1.73 ± 0.12m, and body weight was 62.8 ± 3.7kg. This study used 3 Panasonic Handycams, a calibration set, 3D Frame DIAZ IV motion analysis software, and a speed radar gun. Normalization of the kinetic motion score of the shoulder, elbow, and wrist joints was calculated using the inverse dynamics method. The t-test was used to determine the significance of motion kinetic difference of the two different ...

This study aimed to assess the association of the mechanical variables derived from the force-velocity (FV) profile (i.e. theoretical maximal force [F 0 ], velocity [V 0 ] and maximal power output [P max ]) with change of direction (COD) performance in soccer, basketball and tennis players. Fifty-four male athletes (soccer n = 23; tennis n = 16; basketball n = 15) were assessed for the vertical (Vrt) and horizontal (Hzt) FV profiles, COD with the dominant (D) and nondominant (ND) legs, using the modified 505 test, and sprint. Hzt FV profile parameters showed stronger associations with performance than Vrt FV profile in the three sports. Specifically, the Hzt parameter most strongly associated with COD performance was F 0 in tennis (r =-0.83; p<0.001) and P max in soccer and basketball (r =-0.79; p<0.001). Associations between sprint times and COD test ranged from (r = 0.73 to 0.82) in soccer players, (r = 0.74 to 0.87) in tennis players and (r = 0.62 to 0.85) in basketball players, respectively (p<0.05). Considering the whole sample and the random effect of the type of sports, an improvement in sprint acceleration (i.e. one N/kg increase in F 0 and one W/kg in P max) was associated with-0.15 s and-0.04 s to complete the 505 test, respectively. In conclusion, our results suggest the potential usefulness of assessing the Hzt FV profile to maximize acceleration capabilities through training interventions which, in turn, may translate into improved COD performance. However, further longitudinal and experimental research is needed to confirm this hypothesis.

The shoulder is a unique and complex joint in the human body with three bones and four joints, which makes it the most unstable joint in the body due to the amount of motion. To improve approaches toward understanding the performance of overhead throwing movements, this systematic review summarizes the type of analysis related to shoulder biomechanics involving overhead sporting motions. A search of seven databases identified 33 eligible studies, which were subsequently scored using the Modified Coleman Methodology Score scale. A total of nine articles from badminton, seven from baseball, five from volleyball, five from tennis, three from cricket, and one from softball were reviewed. All 33 studies evaluated shoulder kinematics and 12 of them also investigated the forces and torques (kinetics). The most common methods used were 3D motion analysis (76%), digital video cameras (15%), electromagnetic tracking system (6%), and finally 3% used IMU sensors. Overall, shoulder external rota...
Effect of Fatigue on Biomechanical Variable Changes in Overhead Badminton Jump Smash
Annals of Applied Sport Science, 2020
Background. The badminton forehand overhead jump smash is one of the high speed and powerful motions among various racket sports. Objectives. The purpose of this study is to analyze the effect of fatigue on the kinematic variable movement changes during overhead jump smash in badminton. Methods. This study is descriptive quantitative research with the pre-test and post-test design methods used to obtain data from 15 male badminton players, aged 19.4±1.6 years, height 1.73 ± 0.12 m, and weight 60.8 ± 3.7 kg. The study used three high-resolution handy-cams, motion software Frame DIAZ IV, and 14 point manual markers to analyze body segments' movement when carrying out a jump smash. Furthermore, an ergo treadmill was used to test the players' level by running. Results. The results showed that the shuttlecock velocity was faster during pre-fatigue (188 km/h) than under the condition (145 km/h). A significant difference showed in the angle of shoulder internal rotation (p=0.048) and wrist palmar flexion (p=0.037) at the instant of maximal shoulder external rotation phase. Furthermore, there were significant differences in the shoulder's internal angular velocity (p=0.042), elbow extension (p=0.035), forearm supination (p=0.024), and wrist Dorsi dorsiflexion.040). Conclusion. In conclusion, fatigue reduces players' performances during jumping smash in badminton, thereby leading to slower shuttlecock speed and changes in body segment movements.

Badminton is the fastest racket sport in the world with smash speeds reaching over 111 m/s (400 kph). This study examined the forehand jump smash in badminton using synchronised force plates and full-body motion capture to quantify contributions to shuttlecock speed through correlations. Nineteen elite male Malaysian badminton players were recorded performing forehand jump smashes with the fastest, most accurate jump smash from each player analysed. The fastest smash by each participant was on average 97 m/s with a peak of 105 m/s. A correlational analysis revealed that a faster smash speed was characterised by a more internally rotated shoulder, a less elevated shoulder, and less extended elbow at contact. The positioning of the arm at contact appears to be critical in developing greater shuttlecock smash speeds. Vertical ground reaction force and rate of force development were not correlated with shuttlecock speed, and further investigation is required as to their importance for performance of the jump smash e.g. greater jump height and shuttle angle. It is recommended that players / coaches focus on not over-extending the elbow or excessively elevating the upper arm at contact when trying to maximise smash speed.

The aim of this case study was to identify the effect of the upper arm definition on shoulder and elbow kinematics during the badminton smash. A method was proposed that corrects the false external rotation when using the shoulder-elbow-wrist plane based on the carrying angle (ISB-2C) and compared to ISB recommendations for defining the upper arm (ISB-1 and ISB-2). Differences were found in shoulder and elbow kinematics, in particular angular velocities. Both magnitude and the time history of the angular velocity were affected. In particular, use of the medial and lateral epicondyles was unable to detect a reasonable signal for pronation/supination. ISB-2C reduces some of the problems associated with ISB-1 and ISB-2 e.g. soft-tissue artifact, proximity of medial and lateral epicondyles to the humeral longitudinal axis and false external rotation caused by the carrying angle.
Relationships Between Whole-Body Kinematics and Badminton Jump Smash Racket Head Speed
2020
The purpose of this study was to identify kinematic determinants of shuttlecock speed in the badminton jump smash. Three-dimensional kinematic (400 Hz) data were collected for 18 experienced male badminton players using an 18 camera Vicon Motion Analysis System. Each participant performed 12 jump smashes. The trial with the fastest shuttlecock speed per participant was analysed using an 18-segment rigid body model. Parameters were calculated describing elements of the badminton jump smash technique. Four kinematic variables were significantly correlated with racket head speed. Greater peak wrist joint centre linear velocity, jump height, shorter acceleration phase, and greater shoulder internal rotation at shuttlecock / racket impact.

The aim of this study was to compare the kinematics of the overarm throw for different sports. Eleven elite female handball players and nine elite female volleyball players were selected as subjects for the study. Arm and forearm segment movement in the backswing and acceleration phases of players performing the volleyball spike and the handball jump shot were evaluated. Video data were captured using two Sony 50Hz cameras and were digitized and analyzed using Simi Motion Analysis 5.5 program. In the backswing phase, there were significant differences in the angular width, velocity and acceleration between the volleyball players and handball players on the transverse, vertical, and sagittal planes of the motions (p<.01). In the acceleration phase, the statistically significant difference was found in the angular width of the arm segment motion on the transverse plane (p<.05). On the sagittal plane, the significant difference was found in the angular width, velocity, and acceleration of the arm motions between the volleyball and handball players (p<.05). These results suggest that volleyball players use vertical flexion more frequently, thus increasing the time to gain velocity. Handball players transfer the velocity used in horizontal flexion to the vertical flexion in a short period of time.
A Correlational Analysis of Shuttlecock Speed Kinematic Determinants in the Badminton Jump Smash
Applied Sciences
The forehand jump smash is an essential attacking stroke within a badminton player’s repertoire. A key determinate of the stroke’s effectiveness is post-impact shuttlecock speed, and therefore awareness of critical technique factors that impact upon speed is important to players/coaches. Three-dimensional kinematic data of player, racket and shuttlecock were recorded for 18 experienced players performing maximal effort forehand jump smashes. Joint angles and X-factor (transverse plane pelvis-thorax separation) were calculated at key instants: preparation, end of retraction, racket lowest point, turning point and shuttlecock contact. Peak shoulder, elbow, and wrist joint centre linear velocities, phase durations and jump height were also calculated. Correlational analyses were performed with post-impact shuttlecock speed, revealing significant correlations to peak wrist joint centre linear velocity (r = 0.767), acceleration phase duration (r = −0.543), shoulder internal/external rota...
Kinematic differences between professionals
COACHING & SPORT SCIENCE REVIEW METHODS Twelve (6 males, 6 females) right handed young tennis players, aged 12-16 participated in this study, that are playing in tournaments of the Hellenic Tennis Federation (age: 13,8±1,22 years, height: 167,5±10,11 cm, mass: 55,20±11,15 kg) and 12 professionals who participated in Roland Garros, 6 men and 6 women. Instrumentation The Optitrack kinematic optical analysis system (Natural point Systems Inc., USA) was used to conduct the research. The system uses 9 infrared cameras (Flex 3, Natural Point Systems, USA) with a sampling frequency of 100 Hz, 0.3 Megapixel resolution (640 x 480 pixels). The system software Arena (V.1.15, Natural Point Inc., USA) was implemented for all measurements. Experimental setup The subjects performed a standard warm-up, followed by a 10-minute working out of all three different serves. The athletes then performed the three different services, flat, slice and topspin with three attempts each, which were recorded. The best attempt that was considered representative to analyze was that in service, the ball had to pass over the line of a 0.914m-high tape.
