長期從事運動訓練對12分鐘跑走、血壓、心跳率、及血中抗氧化劑的影響

本研究的目的在於探討長期從事有氧及無氧運動訓練對男性運動員12分鐘跑走成績、血壓、心跳率、血中超氧化歧化? (SOD)、及麩胱甘?過氧化? ( GSH-Px)等抗氧化?的影響。本研究以34位長跑(14位)、短跑(12)、及一般大學(8位)男生自願參加本研究之受試者,分為長跑組、短跑組、及控制三組。運動組的受試者每週6天、每天4小時的訓練;而控制組則沒有限制。所有受試者皆作12分鐘跑走測驗;並經八小時禁食後由橈靜脈抽取後、立即實施離心、並以-30(C冷凍、然後用美國Calbiochem公司所製造的SOD及GSH(麥夫胱甘月太)試劑分析血中 SOD 及GSH-Px。各組間12分鐘跑走成績、血液中SOD、及GSH-Px以單因子變異數分析;薛費事後考驗其差異情形;顯著水準設在α= .05。本研究所得的結果如下:1.與短跑組及控制組比較:長跑組擁有較好的12分鐘跑走成績(P < .05)、較低的安靜心跳率(P < .05)。但短跑組及控制組間沒有差別。2.與短跑組及控制組比較:長跑組血中GSH-Px較高(P < .05)。但短跑組及控制組間沒有差別。3.三組間的血壓、血中SOD沒有差異。本研究結論:長期從事運動訓練,特別是從事長跑訓練有助於增進心肺耐力及降低安靜心跳率。因此欲增進個人的有氧能力,應可以從事長跑或是慢跑訓練。另外,長期從事長跑訓練雖有助於增進心肺耐力,但因血中GSH-Px較高顯示:從事這長期運動訓練有增進氧化性壓力的可能,因此長期從事這種運動需補充如維生素C、E、及β葫蘿蔔素等抗氧化劑。 The purposes of the study were to investigate the effects of the 12 min run, blood pressure, resting heart rate, blood superoxide dismutase(SOD), glutathione perioxidase (GSH-Px) after prolonged anaerobic and aerobic training in male athletes. Total thirty-six volunteer including 12 sprinters (AnG), 14 distance runners (AG), and 8 control group (CG), respectively as the subjects. Both the AnG and the AG take prolonged 6 days per week, 4 hours per day of training. The 12 min-run was used the method of Hwang (1996). Blood pressure (BP) was measured by cuff sphygmanometry. Resting heart rate (RHR) was tested at the radial position. Blood samples were obtained by antecubital vein after eight hours fasting. SOD and GSH-Px were analyzed by SOD and GSH assay kit. One-way ANOVA was used ato analyze the difference among three groups in the score of the 12 min-run, BP, RHR, SOD, and GSH-Px. Turkey LSD post hoc t-test was used to analyze the difference between two groups if F-value were significant difference. The α level was equal to .05. The findings were as follows: 1. There was a significant higher (P < .05) score of the 12-min run, lower RHR in the AG than both AnG and CG, respectively. However, no difference was found in the BP among three groups. 2. There was a significant higher of GSH-Px in the AG than both AnG and CG. No difference was found between AnG and CG. 3. No difference was found in SOD among three groups. AG had a higher score cardiovascular endurance and lower resting heart rate than the other two groups indicating better aerobic fitness after long term of distance run. In other words, if one needs to improve his cardiovascular, one should do some kinds of distance training. Meanwhile, AG had a higher of GSH-Px than both AnG and CG indicating oxidative stress occurred for a prolonged aerobic training. Therefore, antioxidants, such as vitamin C, E, and βcarotine supplementation needs to be intake if one needs to do a long time aerobic training.
