경기력을 향상시키는 역도선수들의 영양관리 및 식이섭취에 대한 문헌 연구

안효작,신정희 한국체육대학교 2000 韓國體育大學校 敎養敎育論文集 Vol.- No.5

The purpose of this study is to research nutritional nanagement and ergogenic aids which may improve competitive performance of weight-lifter. Increased protein intake for the weight-lifters is significantly important during training for increasing muscle mass. The optimal protein intake for weight-lifter training may be 2g/㎏. Moderate dose of arginine and ornithine may have enhanced body fat loss associated with resistance training, an attribute partially modulated by somatotropin Thus, it is recommended to intake arginine/ornithine during weight-lifter training. Nutrition considerations for weight loss recommends daily low-fat, high protein diet since short-term weight loss decreases muscle mass. Continuous efforts for food pattern and ergogenic aids are needed to improve competitive performance.

안문용,안효작 韓國體育大學校 1998 論文集 Vol.21 No.-

The purpose of this study was to examine the effect on the learning of motor skills between intelligence quotient and motor quotient, the subjects for this study consisted of 102 middle school boys with each group 17 persons, and them I.Q. and M.Q. groups were classified into three groups, that is high average(over115), normal average(98∼105), and Low average(80∼89). Each group was trained for six weeks ball throwing, which is divided into the close skill and the open skill, and in addition to this I.Q. groups were under the controled of M.Q. and M.Q. groups were under the control of I.Q. group made up of average(95∼105). The results obtained from this study were as follows 1) M.Q. H.A. group is definitely superior to the others on the motor skill performance. 2) In the effect of learning of motor skill I.Q. H.A. group is superior to any other group. 3) There was no significant differences between M.Q. H.A. group and M.Q. L.A. one but it was found out that there was significant differences same as above in P<0.05 at level under the pre-test between M.Q. L.A. and M.Q. H.A. group and in addition in p<0.01 at level under final test. 4) It was found out that there was significant differences between I.Q. H.A. and M.Q. H.A. groups under the final tests through the official approval in significant differences, and showed in p<0.01 at level between I.Q. H.A., M.Q. H.A. and I.Q. L.A. groups. 5) The I.Q. influenced upon ball throwing skill. These conclusions have such implications as followed 1) We should give especially consideration to M.Q. than any others in selection of athlete. 2) To cultivate good player of sports it is very important to select the distinguished person in both I.Q. and M.Q. aspect. 3) In selection we should exclude the person who is under L.A. in I.Q. and M.Q.

Eight healthy males performed moderate training program 3days per week for 10weeks. Strength was measured before and after weight training program using a Cybex Ⅱ isokinetic dynamometer set an angular velocity at 60???S?? muscle strength, 180???S?? muscle power, 180????S??50 repetition muscle endurance, respectively. Isotonic one repetition maximum (1RM) was measured before and after training program. Muscle biopsies were taken before and after training from vastus lateralis muscle. Obtained muscle sample serially was cutted with 10??m thick and stained for myofibrillar ATPase with preincubation at pH 10.3, 4.6, and 4.37 for identifing type Ⅰ, Ⅱa, Ⅱb and Ⅱc fibers, resectively. Peak power output was 424 watt and increased by 10.5% after the weight training. Weight training resulted in significant increase one repetition maximum for each types of exercise. Weight training resulted in significant hypertrophy of all types : type Ⅰ (24%), typeⅡa(30%), typeⅡa(9.4%), typeⅡc(35%). In addition, the training resulted in a decrease capillaries of type Ⅰ, Ⅱa, Ⅱb fibers with a concomitant increase in type Ⅱc fibers, suggesting that moderate weight training may lead to muscle hypertrophy and possible fiber type conversions.

I have intestigation 10 regions of the body and the stabilization method of 4 regions of joint in order to examine in to the sports injury of elite players, for an year, with the object of inverstigation being 718 athletes of 23 events As a result of the inverstigation I got to the conclusion as follows. 1. The sports injury occurred most frequently in september(1890) and april(1782) for an year, and it did most rarely in July(379). 2. The event in which the sports injury occurred most frequently was Handball, and the next sequence was Hockey(1075), Wrestling(949), Taekwondo(945), Judo(892), Shot put(885). 3. The event in which the sports injury occurred most rarely was Swimming comparitively There occurred few sports injury in Canoe(69), Boxing(97), Shooting(142), Rowing(148). 4. Of all the regions of the body, The injury of the ankle joint occurred most frequently and the next sequence was the knee joint(1,411), the Lumber vertebra(1,004), the cervical vertebra(684), the shoulder joint(551). There was a very small number of injury in the finger(228), the elbow joint(232), and the hip joint(149). 5. In the stabilization method, the ankle joint is 43.8%, which is the highest percent, the wrist joint being 41.81%, the knee joint being 8.56% and the elbow joint being 5.83%. Judging from the above conclusion, I think that the sports leader to say nothing of the elevation of players power on the game, should protect players from sports injury through the sufficient warming up exercise and the sdvance teaching on sports injury. moreover The sports leaders make the players proteckt well the region of body which is injured most in their own event, and prevent the individual and the team from suffering a loss of power on the game being caused by sports injury.

Following is the conclusion based on a comparative analysis of technical physical strength of athletes; male representative players of Korea and China, ordinary male players of Korea, female representative players of Korea and Taiwan, and ordinary female players of Korea 1. male weight-lifter 1) In terms of technical strength, Chinese representative players was ahead of Korean players, but in terms of percentage, it showed just the opposite, the shows that Korean players are required to intensify their treir training for enhancing technical strength. 2) In snatch, players from both countries showed almost the same level, while in clean and jerk, Korean representative players presented more outstanding performance. 2. female weight-lifer 1) In terms of technical strength, Korean representative players were backward with a wide gap compared to Taiwanese representatives, and in terms of percentage, Korean players were all behind them except for military press. In the meantime, Japanese players wear overall behind Korean representatives, but in high snatch, as well as in high clean push jerk, they were ahead of Korean representatives, and they also recorded the highest figure in terms of percentage. 2) In terms of snatch, both Korean and Japanese representatives shared 58%, and Taiwanese representatives showed 62%. In clean and jerk, the top was Taiwanese representatives who recorded 79%, and the second was Korean representatives who were ahead of Japanese representatives. The gap between snatch and clean and jerk was almost the same the same level of gap between Taiwan and the world record. This demonstrates thet in order for Korea to maintain a continuous superiority, Korean male players are required to supplement technical strength, while female players are required to undergo a comprehensive re-training for both technical aspects and physical strength.

The purpose of this work is to provide an optimal information program to the weight lifting coaches to enhence an competability, by comparing the corelation between physical strength and competition records with 27 junior highschool students, 30 senior highschool students, and 30 adult weight lifters. The fruitful research findings have been drawn from the work: 1) competition records indicate that the record has been downed 3-5% in snatch, 3-4% in clean jerk at the competition. In other words, snatch reaches at the level 78-79% of clean jerk, high snatch at 86-89% of snatch, high clean at 78-88% of squat clean in the recods. Also military press occupies 68-69% of snatch, and jerk 1-3%, clean 5-6%, front squat 16-17%, dead lift 25-30%, and back squat 35-40% of clean jerk, respectively; 2) it can be found that light weight division is an optimal for junior highs to exercising their performance, middle weight for senior highs or adults to performing competability on the basis of physical strength, and adult lifters are considered as the strongest among the three groups of participants which represent junior highs second and senior highs least in the back squat.
