The study is for effect of sling exercise and proprioceptive neuromuscular facilitation on foot pressure and range of motion for strengthening quadriceps femoris and hamstring in accelerating training after total knee replacement. The study of subject is woman 40 enforcing total knee replacement on both of knees in July 2002, getting surgery again (total of two times) from infection on left knee joints in September 2003 and April 2004. The exercise was applied with level of not being hard on body and pain by total knee replacement exercise, sling exercise and PNF leg pattern exercise for 3 time a week. The study showed with significant differences to pressure rate of left and right side of subject before and after exercise on foot pressure. The measuring angle was increased in range of motion.

In this study, muscular functions, cross-sectional area of muscle and were analyzed through targeting 12 males in 20s and 30s and dividing them into two group: in the group of 6 men for 50% 1RM one repetition maximum and in the group of 6 men for 80% 1RM one repetition maximum, by using the one repetition maximum training program by the types of intensities, and its findings are as follows. 1. Changes in muscular functions 1) In the respect of the isokinetic muscular functions, there was no significant difference between groups, but in both groups, there was a significant difference between the periods, 12 weeks after the exercise. 2) In the respect of the change in 1RM of Smith Squat, there was no significant difference between groups, but there was a significant difference between the periods in 50% 1RM group 6 weeks after the exercise compared to before the exercise and the difference in 80% 1RM group appeared significant 6, 9 and 12 weeks after the exercise than before the exercise. 3) In respect of the change in 1RM of Squat, there was no significant change between groups but both groups showed significant differences after 6, 9 and 12 weeks after the exercise between the periods. 4) In respect of the change in 1RM of Leg Press, there was no significant difference between groups, but between the periods, 80% 1RM group showed a significant difference 6, 9, and 12 weeks after the exercise. 2. Changes in cross-sectional area of muscle 1) There was no significant difference between groups. But both groups showed a significant difference between the periods 12 weeks after the exercise compared to before the exercise.

This research applied the short-term diet control and training program to target the seven Judo professionals who often reduce weight in a short period of time and seven members of the social club who have no experience with excessive weight reduction in order to analyze change in the electrolyte, enzyme activation level in the body after a match and the excessive short-term weight reduction. The following conclusions were reached. 1. Change in the electrolyte 1) As for the change in the Ca, it was significantly low in the two groups during excessive reduction period, but it was significantly high after five minute-long match when it comes to excessive reduction(after six days). It was significantly low during recovery period. 2) As for the change in the Na, it was significantly high in the two groups when it comes to the appropriate reduction (after two days) compared to before the reduction. However, there was no change for the excessive reduction(after six days) prior to the reduction. Moreover, excessive reduction(after six days) was significantly high in the two groups after five minute-long match, and it was significantly low during recovery period. 3) As for the change in the K, it was significantly low in the two groups when it comes to the appropriate reduction(after two days before the reduction. Moreover, excessive reduction(after six days)was significantly low in the two groups after five minute-long match, but the recovery period was high. 4) As for the change in Mg, the two groups increased significantly during excessive reduction period. As for the excessive reduction(after six days), it increased significantly after five minute-long match as well, and it decreased significantly during recovery period. 2. Change in the enzyme activation level 1) As for the change in the LDH, it did not manifest significant change for the two groups during excessive reduction period, but it was high after five minute-long match after excessive reduction. It was low during recovery period. 2) As for the change in the CPK, it did not manifest significant change during the excessive reduction period in case of the group of Judo professional, but as for the group comprised of aficionados, it was significantly high in the appropriate reduction(after two days). In the two groups, they were high after five minute-long match for the excessive reduction (after six days), and they were low during recovery period. 3) As for the change in SOD, it was significantly low in the two groups during excessive reduction period, but it was significantly high after five minute-long match. During recovery period, it was significantly low in case of the group of Judo professionals, while it was numerically low in case of the group comprised of aficionados. The above mentioned results show that the Judo professionals in Korea can reduce weight excessively in a short period of time, with in 6-7% of the weight. However, when this weight reduction is continued for a long time, this can cause abnormal state. Thus, when the short-term weight reduction continues, it can exert negative impact on the electrolyte, enzyme activation level. Although there are differences in case of the Judo professionals depending on the individuals physical state and characteristics when it comes to the excessive short-term weight reduction, excessive weight reduction can produce negative results when it comes to the improvement of competition ability and on the condition before competition as well as competition ability. Result of this research will be leveraged, to produce important base data for conducting additional research to ensure improvement of competition ability when professionals exercise, following the scientific reduction method and appropriate short and long term periods for weight reduction.

The purpose of this study is to examine the effects of acceleration core stabilization on anterior cruciate ligament(ACL) reconstruction in taekwondo player after exercise training were performed for 24 weeks with case study. This study compared and analyzed the effects of isokinetic muscle function and visual analog scale(VAS) of taekwondo player on ACL reconstruction. 1. The isokinetic muscular function of the knee increased at the angular velocity of 60°/sec and the peak torque extension was similar to the unaffected side of the affected side. 2. The isokinetic muscular function of the knee increased at the angular velocity of 60°/sec and the peak torque flexion was similar to the unaffected side of the affected side. 3. The knee VAS decreased significantly after exercise training than before exercise training.

In this study, two times of exercises a week for 8 weeks were implemented by selecting a total of 30 students, 10 students of squat group, 10 students of overhead squat group and 10 students of control group from 30 male students in grade 4 to 6 in an elementary school located in Gyeongsangbuk-do, in order to investigate the effect of overhead squat exercise on body shape change of elementary school students. The analysis results before and after exercise were as follows: The cervical angle from the side view: The overhead squat group showed a statistically significant difference after exercise(p<.001). In scapula height from the back side view(p>.05) in the squat group, but there was a statistically significant difference found in the overhead squat group(p<.05). It is considered that this study helps better understand what kind of positive effects the overhead squat exercise will bring in children’s body shape change and it can be provided as a basic data for the development of a body correction exercise program for growing children.
