Abdurrahman, M.Kes., (2) Karimuddin, S.Pd., M.Pd.Kata kunci: kecepatan reaksi, keseimbangan, keterampilan Tae Kwon DoTae Kwon Do merupakan seni beladiri yang berasal dari Korea, seni beladiri Tae Kwon Do lebih mengutamakan kaki daripada tangan pada saat melakukan penyerangan, pada dasarnya beladiri Tae Kwon Do hampir sama dengan beladiri lainnya semua anggota badan dapat digunakan, akan tetapi beladiri Tae Kwon Do lebih dominan dalam penggunaan kaki. Penelitian ini bertujuan untuk mengetahui Hubungan Kecepatan reaksi dan keseimbangan dengan keterampilan Tae Kwon Do pada atlet Tae Kwon Do PPLD Provinsi Aceh Tahun 2017. Penelitian ini menggunakan metode penelitian deskriptif dengan teknik analisis korelasional. Populasi dalam penelitian ini adalah atlet Tae Kwon Do PPLD Provinsi Aceh yang berjumlah 13 orang. Teknik pengambilan sampel yang dilakukan adalah total sampling. Teknik pengumpulan data dilakukan dengan cara: (1) tes kecepatan reaksi (whole body reaction) (2) tes keseimbangan (bass test) (3) tes keterampilan Tae Kwon Do. Teknik analisis data dilakukan dengan menggunakan rumus analisis korelasi ganda. Berdasarkan hasil analisis data,temuan penelitian ini dapat di kemukakan sebagai berikut: terdapat hubungan yang positif dan signifikan antara kecepatan reaksi dan keseimbangan dengan keterampilan Tae Kwon Do (F=16,52), kecepatan reaksi memberi kontribusi sebesar 42,25%, dan keseimbangan 77,44% dengan keterampilan Tae Kwon Do.Simpulan penelitian ini adalah terdapat sumbangan yang signifikan dari kecepatan reaksi (X1) dan keseimbangan (X2) dengan keterampilan Tae Kwon Do (Y) pada atlet Tae Kwon Do PPLD Provinsi Aceh Tahun 2017. Selain itu juga didukung oleh teknik yang dikuasai oleh atlet, semakin baik teknik yang dikuasai atlet maka hasil yang diperoleh akan semakin optimal

NEW PANNING-VIDEOGRAPHY STRATEGIES FOR THE UNDEWATER MOTION ANALYSIS

The purpose of this study was to evaluate, through simulation, two new panning-videography strategies based on single continuous control volume (continuous-volume approach) in an effort to overcome the shortcomings of the previously reported method that was based on a set of discrete control volumes (discrete-volume approach). Two continuous-volume strategies were tested: the large-frame strategy and the small-frame strategy. A series of camera calibrations were performed based on a theoretical refraction model and an imaginary experimental setup. Both strategies provided continuous DLT parameter-pan angle curves and demonstrated the potential to provide more reliable calibration results than the discrete-volume approach with less discontinuity in the reconstructed object space and less chance of extrapolation

HOW TO WRITE MANUSCRIPTS AND RESPOND TO REVIEWERS' COMMENTS FOR 'SPORTS BIOMECHANICS'

The purpose of this paper is to outline the fundamental writing principles for the manuscripts to be submitted to Sports Biomechanics and how to respond to the reviewers' comments after a review. General and section-specific writing guidelines are presented along with the recommendations for the preparation of the point-by-point responses to the reviewers' comments

Studies on the Density of Soybean Aphids in Different Cultivars, Planting Dates and Spacings

In order to evaluate the fluctuation of the soybean aphid (Aphis glycines Matsumura) population, six leading soybean cultivars were planted on five different planting dates with different plant densities. The survey of aphid population and climate condition was made from June through September in 1978. According to the differences of planting dates and plant density the soybean aphid populations were varied, and varietal response to the aphid was significantly different. Counting of aphid infestation on the top third trifoliate leaf seemed to be efficient for the estimation of soybean aphid population.Originating text in Korean.Citation: Chung, K. H., Kwon, S.

THE CHARACTERISTICS OF DOUBLE KICK IN THE AIR DURING ACTIVE AND PASSIVE ATTACK FOR ELITE TAE-KWON-DO ATHLETES

The purpose of this study is to discuss the reaction time and movement time of the double kick in the air (DKA) of the active and passive attacks for elite tea-kwon-do athletes. The experiment takes six male tae-kwon-do athletes (average age: 20.5 yearold; average height: 174.8cm; average weight: 63kg) who won the national match in the past 2 years as the subjects. A high speed camera (120Hz) was used to shoot their movements, which is quantified by a Silicon Coach at the same time. Based on the experimental result, the DKA can be a long, short, or rapid jumping attack movement, whose vertical displacement is large and the rolling angle of the body in the air is large. Therefore, it is suitable for the combo attack after the active attack in the competition

The Prediction Of Athletic Coping Skills Inventory, Leg Muscle Strength, Agility, Torso Flexibility, Eye-Foot Coordination, Leg Muscle Power With Idan Dollyo Chagi Tae Kwon Do Kyorugi Learning Result (Correlational Study on Player Tae Kwon Do 15-20 Year Age Group Class Under 54 Kilogram at Banyumas District)

This research aims to find out: (1) the prediction of athletic coping skills inventory with the idan dollyo chagi tae kwon do kyorugi learning result, (2) the prediction of leg muscle strength with the idan dollyo chagi tae kwon do kyorugi learning result, (3) the prediction of agility with the idan dollyo chagi tae kwon do kyorugi learning result, (4) the prediction of torso flexibility with the idan dollyo chagi tae kwon do kyorugi learning result, (5) the prediction of eye-foot coordination with the idan dollyo chagi tae kwon do kyorugi learning result, (6) the prediction of leg muscle power with the idan dollyo chagi tae kwon do kyorugi learning result, (7) the prediction of athletic coping skills inventory, leg muscle strength, agility, torso flexibility, eye-foot coordination, leg muscle power with the idan dollyo chagi tae kwon do kyorugi learning result. This research employed the descriptive approach with the methodology correlational. The population of the research in the tae kwon do players age group 15-20 years under 54 kg class Banyumas district, as many as 27 players. The sampling technique was saturated sampling, the size of the samples taken are as many as 27 players. Data analysis technique used technique correlation analysis. To find connectivity (whereabouts of prediction) between predictor variables with criterion variable that is done with correlation analysis product moment. The results of this research showed that when the factors of athletic coping skills inventory, leg muscle strength, agility, torso flexibility, eye-foot coordination, leg muscle power simultaneously having the correlation with the idan dollyo chagi tae kwon do kyorugi learning result, soit will be the happen increased of idan dollyo chagi tae kwon do kyorugi of 0.045 every increase in a rating score of athletic coping skills inventory, 0.037 every increase of leg muscle strength, 2.059 every increase of agility, 0.106 every increase of torso flexibility, 0.353 every increase of eye-foot coordination, 0.001 every increase of leg muscle power
