The method used was descriptive quantitative, and the data analysis technique was an assessment of the average test difference. Moreover, the sample was 6 skilled and 6 amateur male player groups, with an average height of 1.67 ± 2.43 m, weight 72.4 ± 86.3 kg, and age 25.4 ± 36.2 years. According to the results, four indicators revealed significant differences among the ten kinematics variables investigated, including club speed at impact (P = 0.038), lateral bend after impact ball (P = 0.041), hip rotation at the top (P = 0.045), and shoulder rotation (P = 0.028). In summary, the long drive swing technique in producing maximum ball speed is dependent on the harmonization of the motion sequence from the lower body to the swing of the stick. Furthermore, the rotational speed of the hip joint at the beginning of the downswin followed by the shoulder angular velocity is a movement characteristic of professional players.

Populasi penelitian ini adalah anggota Unit Kegiatan Mahasiswa (UKM) Bulutangkis Universitas Pendidikan Indonesia (UPI). Peneliti mengambil populasi dari UKM Bulutangkis UPI yang didalamnya terdapat persaingan yang cukup ketat untuk mendapatkan tempat sebagai wakil dari Universitas Pendidikan Indonesia untuk menghadapi kompetisi nasional antar mahasiswa 2017. Sampel yang diambil adalah delapan anggota UKM Bulutangkis UPI. Penelitian ini bertujuan untuk (1) mengetahui teknik pukulan apa yang banyak menghasilkan skor di nomor tunggal putra dan di nomor ganda putra UKM Bulutangkis UPI; (2) mengetahui teknik pukulan yang spesifik pada masing-masing nomor pertandingan tersebut. Dilaksanakannya penelitian ini adalah sebagai syarat untuk menempuh gelar sarjana sains di Universitas Pendidikan Indonesia. Dari penelitian ini di dapatkan bahwa, pada tunggal putra UKM Bulutangkis UPI teknik pukulan yang banyak...

Objective: The purpose of this study was to investigate the effect of cardiorespiratory fatigue on throwing ball velocity related to kinematics motion changes in baseball. Methods: The study samples included 12 male baseball athletes (19.3 ± 2.8 years old, height of 1.71.4 ± 3.1 m, and weight of 64.3 ± 3.6 kg). A descriptive quantitative method approach was used. The instruments included two high-resolution handycams (Sony HXR-MC2500, Japan), a high-speed camera (Fastec Imaging TS5-H, USA), a radar speed gun (Bushnell 101922, Germany), a 3D force platform (The AMTI Optima Series 20210, USA), 14 point manual markers, a motion capture system software (Frame DIAZ IV, Japan), and a heart rate sensor (Polar H10, Finland). Results: The results of this study showed that there were...

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.
