啦啦隊組訓12週對大專女子抗氧化能力的影響

Abstract

本研究目的是探討12週啦啦隊組訓對大專女子過氧化傷害與抗氧化能力的影響。受試者以大專啦啦隊女子運動員18人為實驗組，一般同齡學生14人為對照組進行研究，實驗組每週組訓三天，每天訓練三次，每天訓練時間共5小時，並於綜合競賽隊形練習時段監測運動強度，訓練前後各受試者接受血液分析。檢測指標包括：以化學呈色法(Colorimetric method )測定過氧化物歧化酶(SOD), 谷胱甘肽過氧化物酶(GPX), 丙二醛(MDA)，同時採用酵素速率法(Enzymatic rate method) 測定肌酸激酶(CK)與乳酸脫氫酶(LDH) 。各指標在組訓前、後的差異以相依樣本t-test檢驗。結果發現：一、啦啦隊訓練運動強度以個人心跳率來看，最低平均為67.89±3.66次/分鐘，最高平均為203.89±9.37次/分鐘，全程運動強度總平均達到156.21±6.31次/分鐘，約為預估個人最大心跳率的78.11 %。二、實施啦啦隊組訓12週後，肌酸激酶、谷胱甘肽過氧化物酶等值在組訓前、後的差異未達顯著水準(P>.05)，過氧化物歧化酶在組訓後較組訓前顯著提升(P<.01) ，乳酸脫氫酶、丙二醛等值在組訓後較組訓前顯著降低(P<.05)。十二週啦啦隊運動訓練強度適當，不會對女子啦啦隊運動員產生氧化壓力，造成過氧化的傷害，還能有效提昇個體的抗氧化能力。

Objective: The purpose of this study was to investigate the effects of 12-weeks cheerleading training on the change in antioxidative capacity of college female students. Methods: Eighteen college healthy female students (Mean age、height and weight were 18.11±1.84 yrs、159.94±6.06 cm, and 56.99±11.98 kg, respectively) volunteered to participate as the experimental group, and fourteen age-matched healthy female students were selected as the control group. The experimental group received a regular schedule on cheerleading training (3 days for a week, 3 times a day, about 5 hours practice each day), and the control group were prohibited from any physical training. Fasting blood samples were drawn before and after the 12-week training program for determining the creatine kinase (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD), glutathione peroxidase (GPX) and malondialdehyde (MDA). A dependent t-test was used to compare the differences between pretest and posttest data. Results: It was found that the average training intensity of cheerleading about 78% of individual maximal heart rate. The blood SOD levels increased significantly (P<.01), and levels of LDH and MDA decreased significantly (P<.05) for the experimental group at the end of the cheerleading training, as compared to the onset. There was no effect of training regimen on the activity of CK and GPX (P>.05). Conclusion: The results demonstrated that cheerleading is a moderate exercise. Twelve-weeks cheerleading training may enhance antioxidative capability and reduce oxidative stress in college female students.
