Yes, because as you exercise more, your body needs more oxygen, so you start breathing more heavily, and your heart starts beating the blood around your body faster.
the rate increase as you do more work
when you exercise, the heart rate increases, (as does your breathing pace), so that more oxygen can be carried in the blood to your muscles. The more intense the exercise, the more your muscles have to work, so more oxygen is required and your heart rate will increase. The quicker you heart rate returns to normal, the better your fitness.
hmm heart rate maybe?
Your heart rate will increase when you exercise for a prolonged period or when you increase your effort. An increase in intensity might occur if you are riding your bike and you encounter a hill or a stiff headwind. Your heart rate will increase as you put more effort into maintaining your speed.
yes
Exercise, emotions, drugs can make your heart rate increase.
Depending on how light or heavy exercise is will depend on the change that occurs. Typically during exercise heart rate will increase. This is in order to increase blood flow to the working muscles to allow for increased respiration - in order for the muscles to work efficiently. Therefore the more strenuous the exercise, the more your heart rate will increase. Blood pressure will also increase during exercise and again depends on intensity levels. During exercise such as running/cycling/swimming systolic pressure will increase progressively whereas diastolic pressure will increase only slightly. During weight lifting exercises, both systolic and diastolic pressures will rise. Obviously these effects will vary from person to person, depending on age, gender, exercise level, exercise intensity etc. etc.
basically your heart rate increase as the duration of excersise increases.
Anticipation. Hormones (adrenalin and noradrenalin) are released pre-exercise. These accelerate heart rate and aid in preparing the body for exercise.
When you exercise, certain muscles need more oxygen. Your body does this by bringing more oxygenated blood to those muscles. This is done by an increase of heart rate.
it will increase
Everyone knows that exercise is heart-healthy, but not as many realize that knowing one's heart rate during exercise can make exercise more efficient. To increase cardiovascular endurance and health, heart rate must reach a rate of 65% to 85% of the individual's maximum heart rate. A rough estimate of maximum heart rate can be determined by subtracting one's age from 220. The Kavoren Formula, among others, may provide more accurate estimations. These formulas can be easily found online. A heart rate monitor is useful to monitor heart rate while exercising.
