The effect of a short duration training on blood component by exercises intensity The propose of this study was to investigation the change of blood component after a short duration training. The subjects of this study consist of male college students, two group(A group: 75% HRmax, B group:All-out(95%); 20-26 years), who are following at physical education department in K university. Therefore, The results of this study were as followings; 1.B group(intensity of all-out exercise) was higher than A group(intensity of 75% HRmax) on change of Erythrocyte, Hemoglobin, Hematocrit, Total Cholesterol(p〈.001). 2.There was no difference between two groups for High Density Lipoprtein Cholesterol(p<.05)

The purposes of this study were to analyse and compare the changes of cardiorespiratory function and blood glucose and lactate in rest time and recovery period. The subject in this study were eight male gymnastic athletes(G1) and eight male soccer players(G2) of K University. During the study was measured, compared and analysed the cardiorespiratory function using treadmiill and analysed the blood lactate and glucose using the YSI 2300(start plus). After all of the process we arrived to following conclusions: 1.Cardiorespiratory function The maximum ventilation during exercise showed a very significant difference(p〈.01) and the predominant order of the mean value of this variable during exercise was G1(103.4±8.41l/min) and G2(121.9±11.36l/min). The respiratory rate in rest time showed a very significant difference(p〈.001) and the predominant values were G1(17.8±2.92l/min) and G2(13±1.07n/min). The oxygen uptake in rest time showed a significant difference(p〈.05) and the predominant values were G1 (328.4±49.58ml/min) and G2(275.3±17.97ml/min), and the maximum oxygen uptake during exercise showed a very significant difference(p〈.001) and the predominant values were G1(2906.9±236.66ml/min) and G2(3814±251.37ml/min). The maximum carbon dioxide production during exercise showed a very significant difference(p〈.001) and the predominant values were G1(3827.9±418ml/min) and G2(5014.5±435.06ml/min). The oxygen uptake per weight in rest tome showed a significant difference(p〈.001) and the predominant values were G1(4.7±.88ml/kg/min) and G2(3.7±.36ml/kg/min). The oxygen uptake per weight during exercise showed a very significant difference(p〈.001) and the predominant values were G1(45.1±2.93ml/kg/min) and G2(54.1±4.8ml/kg/min). The oxygen pulse in rest time showed a significant difference(p〈.05) and the predominant values were G1(4.8±.63ml/beats), G2(4.2±.39ml/beats) and the maximum oxygen pulse during exercise showed a very significant difference(p〈.001) and the predominant values were G1(15.3±1.13ml/beats) and G2(20.5±1.25ml/beats). The continuous exercise time showed a significant difference(p〈.05) and the predominant values were G1(16.24±1.67min), G2(19.98±4.16min). 2.The changes of blood glucose and lactate of pre and post-excercise and recovery period: There was not significant difference of blood glucose between rest time and just after exercise and the predominant values after 10 minutes, were G1(4.3±.44mmol/l), G2(5.4±.73mmol/l) and after 20 minutes, were (4±.87mmol/l) and (5.1±.80mmol/l) respectively, and the blood glucose value showed a very significant difference(p〈.05). The blood lactate showed a very significant difference(p〈.05) and the predominant values in rest time were G1(4.5±1.42mmol/1), G2(3±.89mmol/l) and just after exercise, 10 and 20 minutes the lactate did not show significant differences. 3.The systolic blood pressure showed a very significant difference(p〈.05) and the predominant values were, after 20 minutes, was G1(5.1±46mmHg), G2(4.2±1.69mmHg).

This research divided 30 female, who have simple pains in their waist into two groups, a comparative and a contrastive group, and each group consists of 15 persons. 1. Trunk Flexion : It doesn't have any statistically meaningful effects on the contractive group, but has a coefficient of correlation with the comparative group(p〈0.05). 2. Trunk Extension : It doesn't have any statistically meaningful effects on the contrastive group, but has a coefficient of correlation with the comparative group(p〈0.05). 3. Sit-up duration time : It doesn't have any statistically meaningful effects on the contrastive group, but has a coefficient of correlation with the comparative group(p〈0.05). 4. Aquatic rehabilitation execise has effects on flexibility of the waist and muscular power of the abdomen from 0 and 4 weeks to 8 and 12 weeks(p〈0.05).

To evaluate the effect of winter intensive training on pulmonary function in high school baseball players, comparisons of various ventilatory parameters were made before and 3 months of winter intensive training. The subjects were 18 members of a high school baseball players with mean age and caller of 6.45 and 17 years, respectively. The following were mainly observed by spirometry for the study ; respiratiory rate, vital capacity(VC), maximum voluntary ventilation(MVV), forced expiratory volume for 1 second(FEV1), percent FEV1 to forced vital capacity (FEV1%) and forced mid-expiratory flow(FEF25-75%). The result obtanied are summarized as follow. 1.Resipratory rate, tidal volume, forced viatl capacity, 1FEV%, FEF50% and FEF75% showed no significant difference between before and after. 2.MVV in after was significantly(p〈.001) increased to 166 l/min comparing with 136 l/min in before. 3.1FEV in after was significantly(p〈.05) Increased to 4.46 l comparing with 3.76 l in brfore. 4.PEF in after was significantly(p〈.05) increased to 10.40 l/sec comparing with 9.18 l/sec in before. 5.FEF25% in after was significantly(p〈.01) increased to 9.30 l/sec comparing with 8.08 l/sec in before. This suggests that enhanced venyilatory functions in high school baseball players after winter intensive training are primarily due to increased in MVV caused by increase in respiratory muscle strength.
