HOW EXERCISE AFFECTS THE HUMAN BODY
During cardio training, many muscles are involved and a large amount of oxygen is consumed. Typical cardio training is jogging, intense walking, swimming, cycling, dancing, active games and the like.
Aerobic exercises are performed with low and medium intensity. They are distinguished by dynamic, continuous and long-lasting nature of execution (more than 5 minutes), which is accompanied by a high heart rate and rapid breathing.
Regular aerobic exercise leads to the fact that the body uses energy resources more economically. Some researchers attribute this to the fact that the level of thyroid hormones decreases.
How does exercise affect the human body?
- They increase the potential of all human systems and organs – in extreme situations, they will work without overvoltage.
- Improve the circulatory system, help the activity of the heart muscle.
- They increase motor activity and compensate for the harmful effects of hypokinesia (low motor activity).
- They can selectively improve both the motor functions of the body (increasing endurance, muscle strength, flexibility, coordination of movements) and vegetative (improving the work of the cardiovascular, respiratory and other systems of the body, metabolism).
- Promote the effective recovery of both physical and mental performance.
- Improve tissue nutrition.
- At rest, all human systems and organs work more economically.
If you decide to start training, you should determine the functional state of your body and the level of physical fitness. Quite often, subjective sensations can be erroneous, and novice athletes, focusing solely on self-awareness, consider themselves capable of withstanding quite large loads. The result of such errors can be, at best, pain in the muscles and joints, and in the worst case, an overstrain of the cardiovascular system.
Before correcting physical activity, consult a doctor or personal trainer.
