Running can make the line of leg more beautiful. Calf coarsened for wrong running posture
Many people have such concern that running can coarsen the calf, because sprinters' calves are very brawny. But the calves of marathon runners are very thin, because running also firm calf and perfect its line. Calf coarsened for wrong running posture.
In running, when touchdown with forepaws or the whole feet, the calf of the tibia and anterior knee joint will be hurt and its muscle stimulated strongly, then coarsen calf. Correct posture is running as far as possible with the heel, then by ground from heel to sole, which can reduce the pressure of ankles and avoid injuring. Keeping slightly bent for knee and not straight when falling to the ground, so that there is a buffered effect and stretch muscles of calf without strong stimulation. This method won't coarsen calf. We need to make use of all the leg muscles to jump the body when running. To avoid leg like turnip, we can do some stretching movement after running for relaxing tight muscles.
Although adopted the correct running posture, female friends still feel calf is becoming thick in jogging early days, because after running, calf is fatigue, stiff and have tightened feeling, which female make them have illusions.
It's wrong for many people think that running is just an anaerobic exercise. Intensity and drastic running is anaerobic exercise, such as 100 meters, 200 meters, 400 meters and other dash. Sprinters often adopt touchdown with forefeet, so that they can run faster and such running needs the powerful muscle. Therefore, you will find sprinters calves are always coarse. While low- intensity and long-time running is aerobic exercise, such as marathon. Those long-distance runners run 10 kilometers everyday, their legs will not coarsen but thin.
Therefore, the way to avoid coarsening calf is not only to take the correct running posture, but must take low-intensity, rhythmic and long-time aerobic exercise of jogging, which consumes the sugar and fat of the body. The time of jogging needs at least 30 minutes and 1 to 2 hours at most. But the speed can not be too fast to control the heart rate in aerobic exercise, also cannot too slow, or do not have any effects on exercise. More than 20 minutes jogging can large drained the glycogen and also fat.
Please note that those fat persons who want to lose weight are not suitable to have long-term single jogging, for their weight will impact the joints and cause harm to the knee and ankle. But they can have aerobic exercise with the help of elliptic apparatus, mountaineering machine, rowing machine, settled bicycle to lose weight.
