Exercise conducted simultaneously with the consumption of herbal supplements is one of the suggested methods for controlling obesity and its complications. The present study sought to investigate the lipid-lowering effects of concurrent training and green tea (GT) consumption in overweight women.
In this quasi-experimental study, 40 overweight women were selected and stratified into four groups: control (C), GT, concurrent training+placebo (TP), and concurrent training+GT (three tablets containing 500 mg of GT per week; T+GT) groups. Both the TP and T+GT groups performed exercise three sessions per week for 8 weeks. Fasting blood samples were collected before and 48 hours after the last training session.
Low-density lipoprotein cholesterol levels in the T+GT (=0.03) and TP (=0.001) groups were significantly decreased relative to in the GT group and were significantly decreased in the T+GT group relative to in the TP group (=0.001). Meanwhile, high-density lipoprotein cholesterol levels in the T+GT group were significantly increased as compared with in the GT (=0.01), TP (=0.03), and C (=0.04) groups. Finally, total cholesterol levels in the T+GT group were decreased significantly as compared with in the TP, GT, and C groups (=0.001) and triglyceride levels in the T+GT, TP, and GT groups were significantly increased as compared with in the C group (=0.001).
Exercise performed simultaneously with GT consumption in comparison with either alone has a greater effect on improving the lipid profile in overweight women.
与服用草药补充剂同时进行运动是控制肥胖及其并发症的建议方法之一。本研究旨在调查超重女性同时进行训练和饮用绿茶（GT）的降脂效果。
在这项准实验研究中，选取了40名超重女性并将其分为四组：对照组（C）、GT组、同时训练+安慰剂（TP）组和同时训练+GT组（每周三片，每片含500毫克GT；T+GT组）。TP组和T+GT组每周进行三次运动，共8周。在最后一次训练前和训练后48小时采集空腹血样。
与GT组相比，T+GT组（=0.03）和TP组（=0.001）的低密度脂蛋白胆固醇水平显著降低，且T+GT组相对于TP组（=0.001）显著降低。同时，与GT组（=0.01）、TP组（=0.03）和C组（=0.04）相比，T+GT组的高密度脂蛋白胆固醇水平显著升高。最后，与TP组、GT组和C组相比，T+GT组的总胆固醇水平显著降低（=0.001），且与C组相比，T+GT组、TP组和GT组的甘油三酯水平显著升高（=0.001）。
与单独运动或单独饮用GT相比，超重女性同时进行运动和饮用GT对改善血脂状况有更大的效果。
