Why change the number of pulse beats after physical load
Pulse (heart rate, HR) is synchronous with the periodic contraction of the heart, the dilation of blood vessels, visible by the eye and determined by touch. With each heartbeat arteries pulsate when blood is pushed through
them. (The pulse — wave vibrations propagating in the walls of the aorta, and the resulting contraction of the left ventricle of the heart. Most often the pulse is determined by a fumble with three fingers at the base of the hands on the outside over the radial bone or on the basis of the temporal bone. Usually the pulse is considered for 6 or 10 seconds and multiply respectively by 10 and 6 (the account within 6 seconds is used for the height of the load). but it should be noted that the pulse rate changes, the result may differ, so it is better to count a full minute. The pulse healthy untrained men at rest — 75-80 beats per minute, women 60-75. During physical activity, emotional state change, and when associated with deficiency of hemoglobin in the blood and other diseases of the heart rate is increased because the human body responds to standard requirement of the organs and tissues of high blood flow by increasing heart rate.
The pulse rate also affects growth (inverse relationship — the higher the growth, the less typically the number of heartbeats per minute). age (heartbeat of a newborn baby at rest is equal to 120-140 beats per minute, and only to 15 years is the norm). gender (men, on average, the heart rate is somewhat lower than in women). training of the body (in the susceptibility of the organism continuous active physical exercise, the resting heart rate decreases). Professional athletes pulse to the load — 40-50[citation 170 days] beats per minute. After — 90-100. Fitness also affects the heart rate. In untrained heart rate after raising 7 kg dumbbells 100-120 beats per minute. After a short run 120-150 beats per minute. And after serious physical exertion, such as long-running, strong muscles, etc. the pulse can reach 150-205 beats per minute.
To control the quality characteristics of heart rate and oxygen saturation of arterial blood using the method of pulse oximetry.
Pulse is the pulse of blood, which through muscle contraction is ejected from the left ventricle of the heart into the arteries. The pulse rate is measured by beats per minute. Usually the pulse is determined by fumble fingers at the base of the hands on the outside over the radial bone or on the basis of the temporal bones, counting the number of pulses per minute.
The pulse rate varies with age, sex, functional status of the person. In the adult, the resting heart rate is about 60-80 beats per minute. With age, the heart rate decreases. The pulse of a newborn baby alone is about 130 beats per minute, and only by the age of 15 years to reach the standards.
The heart rate in a healthy person is 60-80 beats per minute at rest, rhythmic, without interruption, good filling and voltage. The pulse rate also affects the height of a man – a tall man, the number of heart contractions less. Physical activity, stress, illness, suffering and experiences — all these factors affect the heart rate. During physical activity, the heart rate increases. In some diseases, the pulse rate may increase as a result of the response of the human body to the demand of organs and tissues of high blood flow by increasing heart rate.
