In an effort to elucidate the effect of ethanol on the pulmonary function in athletes, 26 athletic college students were selected. Pulmonary function test was performed after administration of ethanol to the blood ethanol level of 40㎎/㎗. Results of the test were summarized as follows: Forced expiratory volumes were decreased by ethanol, and FVC and FEV_0.5, in particular, showed a significant decrease. Forced expiratory flows were decreased by ethanol. Especially, PEF, PEF_25%, FEF_(200∼1200㎖), and FEF_(25∼75%) showed a significant decrease. MVV was decreased by ethanol ingestion. Alveolar PO_2 and PCO_2 were not changed by ethanol ingestion. Blood pH, PCO_2, PO_2, bicarbonate, base excess, O_2 content and O_2 saturation showed no significant change.

The main purpose of this study was to improve greatly the most important reaction time(RT) and speed of movement (SM) at racket exercise by making program for simulator super quality training (S.Q.T) and applying it. The subjects employed were 25 male athletes composed of soccer players 8, volleyball players 7, shooting players 2, soft-tennis players 2, gymnastics player 1, and rugby football player 1 at the Kyungpook National University. We devided each sport player half and half by means of their pre-testing reaction time, and the subjects were devieded into experimental and control group. Experimental group was drilled by using light stimulus simulator training method and control group was drilled by using sound stimulus simulator training method. The training was practiced 20∼30 minutes a day regularly and 5 times a week for 5 weeks. Two groups practiced concentrically experimental learning by using light and sound simulator equipment by S.Q.T. program under equal condition. The propriety on the training effect was investigated by longitudinal analysis of results tested before and after experiment. As the result of the experiment, superiority and inferiority of two groups was evaluated by trying crosssectional analysis. The results obtained were summarized as follows: 1. Reaction time Experimental group; The performance of this group was greatly improved after experiment. Control group; The performance of this group was greatly improved after experiment. Comparison of two groups; Leftward simple completion time showed a significant difference (p<.01), but the other elements did not showed it. As a whole, experimental group was superior to control group, but statistics showed little difference between the two groups. 2. Speed of movement Experimental group; The performance of all elements were improved after experiment(over p<.05). Control group; The performance of this group was improved at only 4 of 9 elements after experiment Comparison of two groups; The performance of service and dash showed a significant difference (p<.01) and the others did not showed it. But as a whole, experimental group was superior to control group in their performance. 3. Viewing Variance and correlation coefficient at the change of RT and SM, there were differences in the variance. This means that the standard deviation is great; i.e. the individual difference is great. The lower correlation coefficient means that correlationship is low in the performance before and after experiment: i.e. it means that individual difference was decreased because the gap of two groups, correlation coefficient became less. Especially, statistics showed that the record of the lower recorded players could be shortened to a maximum.
