This study is carried out to examine the effect of applying Feldenkrais method, elastic band training and combined training on trunk muscle. The subjects of this study were 32 modern dance majors and they were divided into four groups which consists of 8 peoples each, Feldenkrais method group(modern dance + Feldenkrais method), elastic band training group(modern dance + elastic band training), combined training group(modern dance + Feldenkrais method + elastic band training), and control group(modern dance). Measurement variables which are trunk muscle were measured before training, and after 4 and 8 weeks training and the results are as follow: In the left muscle strength change at Centaur 0°, Feldenkrais method group, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and combined training group had significant increase after 8 weeks training. In the left muscle strength change at Centaur 45°, Feldenkrais method group and combined training group showed significant increase after 8 weeks training compared to before training and after 4 weeks training. Also elastic band training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and elastic band training group significantly increased after 8 weeks training compared to before training. In the left muscle strength change at Centaur 90°, Feldenkrais method group and combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group showed significant increase after 4 and 8 weeks training compared to before training, and elastic band training group significantly increased after 8weeks training compared to before training. In the left muscle strength change at Centaur 135°, there was no significant changes. In the right muscle strength change, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the left muscle strength change at Centaur 180°, combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, combined training group showed significant increase after 4 and 8 weeks training compared to before training. From above results, applying 8 weeks regular program of Feldenkrais method, elastic band training and combined training to modern dance majors showed positive changes on improvement of trunk muscle strength and physical strength. Also this study implemented to verify the effects of trunk muscle strength and body balance through supplementary training program, and showed the effects in the training group and control group after 8 weeks trunk muscle strengthening program. Feldenkrais method, elastic band training and combined training are very effective to improve trunk muscle strength of modern dance majors so that continuous implementation and application of these effective training program shall be provided for strengthening trunk muscle.

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.
