The warm-up exercises have the function of preparing the body for physical or sports activity. They are performed on the basis that a large number of injuries and heart problems such as arrhythmias can be associated with violent and aggressive exercise, without previously warming up the muscles.
The exercises with which the warm-up is carried out are of many types, and even vary according to the activity that you want to do later. However, in all cases the utility is to increase body temperature, which prevents the aforementioned injuries while delaying the onset of fatigue, and reduces muscle pain.
Most people are aware of the importance of the warm-up exercises to the extent that they have ever performed a sports practice with the muscles in a cold state, that is, stiff and hard: even if a person had to run for some circumstance without prior knowledge that they had to do it, they faced that situation. If the physical activity is strenuous and continuous, it is possible that once it is finished the muscles ache greatly.
What happens in the body?
The biological explanation of the warm-up process is that the exercises help to raise the temperature of the body, increase the pulsations, the pressure and blood and the blood flow towards the peripheral muscles. The blood issue is fundamental since in a state of rest, the heart pumps about five liters of blood per minute, distributed throughout the body, while during sports activity this multiplies by five, taking the muscles involved in the exercise a 84% of that flow.
Other processes take place inside the body during elongation, such as elongation. elevation of enzyme activity to produce energy, making the body aware of the imminence of sports activity. In addition, there is a progressive increase in the speed of nerve impulses, and a more rapid diffusion of oxygen from the pulmonary alveoli to the muscles.
The warm-up process should always be done before starting a sporting activity, and it takes around 20 or 30 minutes, depending on the magnitude of the competition: highly competent athletes must devote a capital importance to this stage.
For each muscle there is one or more postures, and the elongation It is always performed from low to high in intensity, with a single smoothly moving movement. Here are some examples of these exercises:
