Abstract : Factors that affect the martial in execute hook kick in order to obtain maximal speed. The speed of kick technique, agility, also concentration degree affect this speed. One of the factor that lack of attention in execute hook kick is the angle of kick, body declivity and front knee. Coordination between basic technique and angle of kick must get attention, since those movement is simultaneous kick. Formulation of the problem posed in this study were: (1) What is the magnitude of the body segment angle and rotation angle sweeping crescent kick that produce energy, style, and speed of crescent kicks to the fighter category greatest heights high? (2) What is the magnitude of the body segment angle and rotation angle sweeping crescent kick that produce energy, style, and speed of crescent kicks greatest fighter category at low heights? Purpose of this study were (1) Determine measurement analysis of the body segment angles, speed, energy, great style kicks, crescent kicks sweep angle of rotation in sports martial arts categories of high stature. (2) Determine the results of measurement analysis of body segment angles, speed, power, great style kicks, crescent kicks sweep angle of rotation in sports martial arts categories of low height. Method that used in these research is descriptive analysis, that is analyse and serve fact sistmatically until easier to understanding and conclude. These research helped by dartfish program, that a software that essentially needed by someone in measure something that can not by eyes. For this research using dartfish with analyzer facility so that can analyze other movement that seen from the body segment angle, movement line, speed, time, also movement. Conclusions from this research is Based on the category of high stature, at an angle of 103.5 0 ≥ crescent kick and corner kick crescent sweep rotation ≤ 150.62 0 to generate the energy, style, and speed of most large crescent kick and quickly and to produce a significant backlash . Under the category of low height, on the corner of crescent kicks 0 ≤ 119.24 and rotation angle sweep of crescent kicks 0 ≤ 163.88 that produce energy, style, and speed of most large crescent kick and quickly and to produce a significant backlash.

Abstract

Abstract : Lactic acid is produced during intense levels of exercise when the oxygen demands of the muscle fibers increase beyond what the blood is capable of delivering. To produce the energy needed, the body begins another process, which works in the absence of oxygen. Lactic acid—a byproduct of this process—locks up your muscles, and because it is an acid it causes your muscles to experience that burning sensation. But lactic acid is completely washed out of the muscles within 30 to 60 minutes after finish the exercise.Since muscle soreness does not show up until 24 to 36 hours later. Over the 24 hours, the damaged muscle becomes swollen and sore. Chemical irritants are released from the damaged muscles and can irritate pain receptors. In addition to the injured fibers, there is increased blood flow from increased activity to the muscle, causing a swelling of the muscle tissues, which causes enough pressure to stimulate pain receptors. Instead of having free-moving muscle fibers the next morning, the fibers that are fatigued, have microscopic tears and are swollen. Key words : lactic acid, skeletal muscle soreness

Abstract

Abstract: This stuy aima to determine the types of research in sports science students S1 theses (in this case the students are expected to hold a sports degree), especially to determine the percentage of students’ S1 thesis which are categorized as  motion analysis. The data in this research were obtained through the study of documentation, by analyzing the students’ S1 thesis which is documented in the library of S1 Sport Science study program. The study was conducted in December 2011. There are 219 S1 thesis titles obtained in the library. The result of study shows that the types of students’ S1 thesis has been done can be categorized as follows: 22,83% (correlation), 30,14% (contribution), 14,16% (quasi experiment), 8.22% (study of comparative), 10,05% (survey), 5.02% (motion analysis), and the remaining 9.59% (profiles, the game statistics, development of instruments, etc.). Based on the classification is shown that the students thesis which are categorized as motion analysis is still very low, that percentage is only 5,02%
