Breathing is very important in long-distance running. Long-distance running belongs to aerobic metabolic exercise, which participates in the circulation of main organs of human body, especially respiratory system. In the process of running, the human body's demand for oxygen is increasing, so we need to pay attention to the breathing rhythm. Under normal circumstances, you can inhale in two or three steps, and pay attention to the rhythm. In the way of inhalation, nasal breathing and mixed inhalation of nose and mouth should be adopted, which can hold the tongue against the upper jaw and avoid the stimulation of direct inhalation of cold air on the chest. In long-distance running, because the oxygen supply lags behind the needs of muscle activity, there will be "maladjustment" (extreme) phenomenon during running, which makes people feel heavy legs, chest tightness and difficulty breathing, and do not want to continue running. At this time, it is necessary to appropriately slow down the running speed, adjust the breathing rhythm, and persist in the determination to run. Soon, the difficulties will be overcome.

Activities and Relaxation after Running Many people are used to going back to rest as soon as they finish running, which is actually not good. After running, the whole body gets activity. At this time, further basic quality exercise can achieve good fitness effect. At this time, you can do a set of extensive gymnastics, and you can also do leg press, kicking, jumping, vertical jumping, one-legged jumping and leg lifting exercises to develop lower limb strength and improve endurance. Don't rush to rest after the whole exercise is finished. You can jump and kick in place, pay attention to the whole body relaxation, swing your arms naturally, and swing your legs alternately back and forth. Then, bend your knees and bend over, clench your fists with your hands or form a knife, and beat your thighs and calves to fully relax your muscles.
