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 : Doping is a substance or prohibited substances and methods to increase performance in sports that are not associated with a medical indication. Drug doping is a group that included stimulant, narcotic analgesics, anabolic steroid group, class betabloker, class of diuretics, and peptide groups hormons and analogues. Selection of amphetamines (stimulants) based on the number of athletes who abuse these types of drugs, especially in the branch of cycling. Amphetamines are substances that stimulate the central nervous system works. The use of amphetamines often consumed cyclist can cause effects such as increased alertness, reduce drowsiness, reduced fatigue, and increased motor activity (physical performance).   Key words : doping, amphetamines, cyclist.

Abstract :VO2 reflects one’s fitness level as a capital for a good athlete besides motivation and basic movement. A high VO2 max can inhibits fatigue caused by accumulated lactic acid in blood. The purpose of this research is to find out the correlation between VO2 max and the velocity of lactate acid recovery after sub maximum physical exercise. The samples were 20 people, divided into two groups, each groups consisted of 10 persons. The first group (untrained) had VO2 max 35-40 ml/kg/min and the second (trained) had 55-60 ml/kg/min. Both groups did sub maximum physical exercise (85% HRM) using ergocycle. The blood lactic acid level was taken as the data from the fingertips three times; before the exercise, after 5 minutes and 15 minutes recovery. The average of group 1’s initial lactic acid was 1.86 ± 0.1955 mMol/l and group 2 was 1.55 ± 0.2014 mMol/l; the average lactic acid after 5 minutes recovery of group 1 was 6.61 ± 0.4408 mMol/l and group 2 was 5.62 ± 0.3994  mMol/l; after 15 minutes recovery, group 1 was 5.96 ± 0.568 mMol/l and group 2 was 2.85± 0.7821 mMol/l. The average decrease of group 1’s lactic acid was 0.650 ± 0.369 mMol/l and group 2 was 2.770 ± 0.693   mMol/l. The pace of group 1’s lactate decrease was  6.5x10-2 ± 3.69 x 10-2 mMol/l minutes and group 2 was 0.277 ± 6.93 x 10-2 mMol/lminutes. The result of ANAVA univariate test showed that the difference of the lactic acid decrease and the recovery pace between group 1 and 2 was very significant (p<0.05) and R Square value was 0,836. There was corelation between VO2 max and the velocity of lactic acid recovery after sub maximum physical exercises ;and the recovery of blood lactic acid level after sub maximum physical exercise was faster in a group with 55-60 ml/kg/min of  VO2 max than in a group with 35-40 ml/kg/min of  VO2 max.   Key words : VO2 max, lactic acid, sub maximum physical exercises.
