第一招:锻炼股四头肌,即大腿前面的肌肉坐在床上或地板上,膝盖向前伸直,在膝盖凹陷处的下方垫一个毛巾卷,紧缩膝盖向下压毛巾卷至少30秒钟然后放松,重复25次为一组,一天两三次即可。这一动作因为不用移动下肢,不必活动关节,所以是一种非常安全的练习。第二招:锻炼大腿后面肌群俯卧在床上,下巴接触到床面。在脚踝处挂一个0,5~1公斤的沙袋,弯曲膝盖,缓慢将小腿抬离床面,再缓慢降下,尚未触及床面时再停一停。重复5~10遍为一组,每天两三次。 The first one: exercise quadriceps, that is, the muscles in front of the thigh sit on the bed or floor, knees forward straight, below the depression in the knees pad a towel roll, squeeze the knee down the towel roll down at least 30 seconds Then relax, repeat 25 times as a group, two or three times a day can be. This action is because it does not have to move the lower limbs, do not have to move joints, so it is a very safe exercise. The second measure: exercise thigh muscles lying prone on the bed, chin to the bed. Hang a 0,5 ~ 1 kg sandbag at the ankle, bend your knees, slowly lift the lower leg from the bed, and then slowly lower, and then stop before touching the bed. Repeat 5 to 10 times as a group, two or three times a day.
