Bicycle Ergometer 運動前, 後 血液成分 變化에 關한 硏究
林恒鎭,金正洙,朴晶來 公州大學校 스포츠科學硏究所 1991 스포츠科學硏究所論文集 Vol.- No.4-5
This study is meant to calculate the change of circulational ability (Heart rate, Blood pressure) and blood components (RBC, WBC, Hb, Hct, Glucose, Total cholesterol, Total protein) at rest (30 minute of rest before exercise), after exercise and at recovery (30 minutes of rest after exercise) by using bicycle ergometer. The boys (5 athletes group, 5 non-athletes group) were chosen form "K" middle school in "K" city and were examined to raise the expectations about exercise. The method of exercise load was decided with a pre-test at 80% of maximum heart rate with bicycle ergometer (Monark : Sweden). 2 minutes of warming up at 50 in 0 kp was done, and soon without rest, main exercise was done for 5 minutes at 50 in 30 kp. Blood circulational ability and blood components were examined three times respectively at rest, after exercise and at recovery. Blood circulational test was taken at sitting position using finger for heart rate and a Sphygmemanometer (Tycos type, Auto) 5cc of blood was collected using one time injector through the antecubital vein and soon 1cc of blood (anticoagulated, EDTA-2k) was examined for blood components change with Auto Cell Counter (ABX : France). The rest of the blood was placed in a plane tube. Later a biochemistrical test was took with Hand Chemistry Analyzer (Gylford : U.S.A) and Auto chemistry Analyzer (Gylford : U.S.A). Experimental items were physique examination (Height, Weight, Chest), circulational ability test (Heart rate , Blood Pressure), hematological test(RBC, WBC, Hb, Hct) and biochemistrical test (Glucose, Total cholesterol, Total protein). The results were compared and analyzed according to experimental items, Standard deviation and mean were made by SAS package program at rest Exercise, and at recovery, The T-test about the difference in average between athletes and non-athletes was made at level of α=0.05, α=0.01 The results are as follows. 1. At rest , the heart rate of the athletes and non-athletes did not have statistical differences, but after exercise, both groups showed rapid increase with concerning difference (p<0.01). 2. At rest, the maximum blood pressure (at systolic) was lower for the athletes group with no statistical significance for both of the groups. After exercise, both groups showed high increase, and at recovery both groups showed quick recover rate. There were no concerning difference both at after exercise and at recovery. 3. At rest the blood components showed less RBC's and WBC's than the normal adults and an average rate of Hb's and Hct's. Only WBC's and Hb's showed statistical difference (p<0.05, p<0.01). 4. After exercise, both groups showed low increase of RBC's Hb's, and Hct's but WBC's showed high increase WBC's Hb's and Hct's showed concerning increase (p<0.05) 5. At recovery, both groups showed approximately 95% recovery rate of RBC's Hb's and Hct's of the blood components, but WBC's showed a high recovery rate of 106%. Only WBC's and Hb's showed statistical difference (p<0.05) 6. At rest, Glucose and Total cholesterol was lower in athletes group but there were no statistical difference in both groups. After exercise both groups showed low increase in them. Glucose showed concerning difference (p<0.01) At recovery, both groups showed rapid recovery rare, but no concerning difference. 7. At rest, Total protein was low in athletes group with no statistical significance. After exercise, both groups showed low increase with no concerning differences. At recovery, both groups recovered quickly, but were no concerning differences. Concluding the above, compared to the non-athletes group, the athlete group showed low numeric value in blood circulating ability and change in blood components at rest, after exercise and of recovery. The low numeric value in blood circulating ability and quick recovery seems to reason form everyday planed and regular exercise in which physical and biochemical changes occur which gives the ability to adjust to the moving parts. The future subject is to understand the effect to the students of early growth which happen by the influence of developing society and to do continuous research of age, sex distinction, and areas to judge the details and intensity of physical strength training, and need to research with long and planned physical strength examination.
