Increased level of blood lipids is one of the risk factors for cardiovascular diseases. Considerable research has done to assess the effects of physical exercises on lipid profile, of which aerobic exercises are the main part of evidence. However, in recent years, resistance exercise has been less investigated. Thus, the present study investigates the effect of resistance exercise on lipid profile in coronary artery disease patients.
This study was a randomized clinical trial. Forty eligible participants were selected through selective sampling and were assigned randomly to either intervention or control groups (20 participants in each group). Fasting blood sample was taken for measurement of lipid profile before, after, and after 4 weeks of the end of intervention. The intervention period lasted 8 weeks and included two exercise sessions of 45-60 minutes per week. Resistance exercise was performed by use of light weights in the range of motion of the elbow, shoulder, and knee joints. The number of repetitions was initially 10 and was gradually increased to 15. Then, the weight was increased by 3-5% and the number of sets too. Data were analyzed on significant level of < 0.05.
In both the groups, the mean and mean changes of lipid profile, before, after. and 4 weeks after the end of the intervention were not significantly different ( < 0.05).
The 8-week of resistance exercise did not lead to a significant decrease in the mean lipid profile.
血脂水平升高是心血管疾病的危险因素之一。人们已经进行了大量研究来评估体育锻炼对血脂谱的影响，其中有氧运动是主要的证据来源。然而，近年来，抗阻运动的研究较少。因此，本研究调查抗阻运动对冠心病患者血脂谱的影响。
本研究为随机临床试验。通过选择性抽样选取40名符合条件的参与者，并随机分为干预组和对照组（每组20名参与者）。在干预开始前、干预结束后以及干预结束4周后采集空腹血样以测量血脂谱。干预期持续8周，包括每周两次45 - 60分钟的锻炼课程。通过在肘关节、肩关节和膝关节的运动范围内使用轻重量器械进行抗阻运动。重复次数最初为10次，逐渐增加到15次。然后，重量增加3 - 5%，组数也增加。数据在显著性水平<0.05下进行分析。
在两组中，干预前、干预后以及干预结束4周后的血脂谱均值及均值变化均无显著差异（<0.05）。
8周的抗阻运动并未导致血脂谱均值显著降低。
