What should be ready for the summer fitness

Preparation activities, commonly known as & other; Warm up & throughout; , hot summer, also used as preparation before fitness activities? Today we talk about summertime fitness exercises together. Fitness (credit/canopy) refers to the preparation before the formal fitness physical exercises, reasonable and full preparation activities any fitness sports, competitive sports training, the important steps must be completed before the games. Now that call to warm up before exercise improve campaigner, of course, is one of the effect of preparation temperature, increased body temperature makes the nerve conduction speed, viscosity reducing muscle, improve muscle stretching and flexibility, studies suggest that temperature per 1 degree, the body’s metabolic rate increases by 13%. And temperature by 2 degrees, meat shrinkage increases about 20%, visible, can raise the body temperature series for sports physiological changes. In the summer, high temperature and sunlight radiation make people itself has high temperature, the viscosity of muscle is reduced, the extension to strengthen, prepare activity time can be shorten than it was in a cold environment movement, but don’t leave out not to be, and because of the elevated temperature is only one of the effect of preparation. Overcome the internal organs of the physiological inertia is the important role of preparation, any object must overcome inertia to move forward, such as when we took a car, train, from the starting to the high speed, physical inertia to overcome. The movement of the body in addition to the objects with the same physical inertia, also has a peculiar to the organism physiological inertia. Movement was regarded as a kind of complex reflection, nerve impulses to muscles by reflex arc conduction, which requires a certain amount of time, and the excitement of dominate visceral autonomic nervous impulse, made by the cerebral cortex, need more subcortical centers, to get to the mercy of the internal organs. Reason has large inertia, reasonable and appropriate exercises can effectively increase the activity of oxygen transport system, improve the pulmonary ventilation and cardiac output, through the stimulation of benign certain load, the capillary network expansion of cardiac muscle and bone, to participate in the activities of the muscle to get more oxygen supply, which can quickly overcome internal organs physiological inertia. If you don’t prepare activity or inadequate preparation, the start of a vigorous exercise, even the summer temperature is very high, also can not adapt to the internal organs, can cause motility disease or injury, such as the movement of the abdominal pain is mainly caused by sudden contraction, oxygen, blood vessel stimulation of metabolites, spasmodic contraction of smooth muscle, etc, this is often occurred in the activists were not fully prepared activities.
