Cycling to keep your legs healthy

　　First of all, the muscles of the lower limbs are much larger than the muscles of the upper limbs. To maintain muscle strength, a considerable amount of exercise is required. In daily life, the habits of using a car instead of walking, exercising less, and walking less will be exposed in old age; secondly, the lower limbs are further from the heart than the upper limbs. Due to the effect of gravity, it is more difficult for the blood in the lower limbs to return to the heart than in the upper limbs. With the increase of age, the elasticity of the blood vessel wall decreases, which is prone to poor blood circulation, causing fatigue in the lower limbs that is difficult to eliminate; thirdly, elderly The accuracy and speed of the transmission of sensations from the lower limbs to the brain and the transmission of motor instructions from the brain to the lower limbs have decreased. Therefore, in order to ensure that people still have a steady gait and walk like wind in old age, the muscles of the lower limbs should be strengthened. exercise , Keep the muscles of the lower limbs strong.

　　I think that in addition to walking, Tai Chi, jogging and other exercises, cycling is a very good way to slow down the aging of the legs. Due to the special requirements of cycling, the upper limbs and trunk mostly perform static work, while the lower limbs mostly perform dynamic work. Long-term exercise can improve the strength and endurance of the lower limb muscles. Due to the redistribution of blood during exercise, the blood supply to the lower limbs is larger. heart rate The changes also vary according to the speed of pedaling action and the ups and downs of the terrain. Repeated practice in this way will enhance the contractility of the myocardium and increase the elasticity of the blood vessel walls, which is beneficial to the blood circulation of the lower limbs. nerve The system's management of the lower limbs can also be coordinated and precise due to exercise training. Now, with the emergence of fixed resistance and power bicycles, more superior conditions have provided convenience for the majority of fitness enthusiasts. Exercisers can design an exercise program before pedaling, and a variety of information will be displayed on the screen while pedaling, such as heart rate, distance, oxygen consumption, speed and time. These displayed test data make it easier for exercisers to grasp and adjust their exercise intensity in a timely manner to achieve the purpose of scientific fitness.

　　Cycling for fitness, if you persevere, will definitely slow down the aging of your legs and at the same time give you a healthy 's physique.
