Haven't exercised in 4 weeks because of virus. When I stand up my heart rate goes up by 30, I'm tired and out of breath and weak. Should I work out?

No exercise now: Under these circumstances the answe should be no until you feel better. Hr that goes up this much with standing implies dehydration--exercising right now will only make that worse. See your doctor and push fluids and nourishment. If still short of breath get an echo to make sure that the virus has not affected the heart or pericardial sac. ...Read more

Y would diastolic BP lower after exercise, is that normal. How quickly should your heart rate go up during exercise and how far. Is 80 high resting ra?

Y would diastolic BP lower after exercise, is that normal. How quickly should your heart rate go up during exercise and how far. Is 80 high resting ra?

Yes!: Normally diastolic blood pressure will fall during exercise and for several hours afterwards. This is because off vasodilation that normally occurs. Systolic BP should always rise. However, in hypertension, the diastolic pressure will rise too, imposing an unnecessary work load on the heart. Increase in heart rate is based on exercise intensity. Normally the HR max is 220-age in years. ...Read more

I'm 18 exercise regularly but am 6ft 200lbs. Sometimes I have a heart rate of 55 but when I exercise it goes up normal. Should I get checked?

I'm 18 exercise regularly but am 6ft 200lbs. Sometimes I have a heart rate of 55 but when I exercise it goes up normal. Should I get checked?

May be normal: The normal resting hear rate is between 60 and 100. The heart rate increases with exercise and people who exercise a lot tend to have lower resting heart rate. Trained marathon runners may have resting heart in the 40's - 50's. If you have dizziness or feel lightheaded when the heart rate is low, you should have it checked. ...Read more

Can you exercise so hard that you go over your max heart rate? If so, is it dangerous?

Can you exercise so hard that you go over your max heart rate? If so, is it dangerous?

Exercise and pulse: Young people can easily exceed the recommended pulse rate of (220-age) x 0.7. First off, it's an artificial, but fair estimate for the average person in average condition. Use it as a gauge for measuring cardiovascular fitness. As you get fit, equivalent amounts of exercise should require lesser heart rates; greater exertion can be done with similar heart rates. Don't over think it or overdo it. ...Read more

When I exercise, my heart rate goes between 160-175bpm. Is this too high for a 37 year old woman? Target heart rate calc says 146 maximum.

When I exercise, my heart rate goes between 160-175bpm. Is this too high for a 37 year old woman? Target heart rate calc says 146 maximum.

Depends: A formula widely accepted is 220-age=maximum heart rate. Keep in mind though that this is a simplistic formula with age as the only variable and standard deviation for this equation is 10 to 15 bpm. Target heart rates for aggressive cardioconditioning are generally recommended at 80% of your calculated maximum for a healthy individual. See your first GP to discuss any possible contraindications ...Read more

A test call head-up tilt table testing could help in the diagnosis. ...Read more

What's a normal change in heart rate with exercise?

What's a normal change in heart rate with exercise?

Increased heart rate: Exercise is cardiovascular (aerobic) if you raise and elevate your heart rate for an extended period of time. Preferably you would like to elevate your pulse to 65-85% of your max hr. Max hr= 220- age. So for example if you are 30yo your max hr = 190 BPM and you would want to elevate your heart rate to at least 125 to 162. If you are strength training it will be a smaller increase than that. ...Read more

Why is my heart rate is high during a moderate intensity exercise? I need some advice.

Predicted heart rate: During exercise, the maximum predicted heart rate for your age is calculated by subtracting your age from 220 (220 - age). At 33 years old that would be 220 - 33 = 187 beats per minute. Any heart rate up to 187 beats/minute during exercise would likely be normal. ...Read more

Is there a way I can naturally lower my heart rate. I exercise everyday, and eat right, yet it still dangerously high as in 100+.

Is there a way I can naturally lower my heart rate. I exercise everyday, and eat right, yet it still dangerously high as in 100+.

I suggest seeing PCP: And may be a Cardiologist to ensure there are NO heart issues, if your Heart rate stays in the hundreds.
Get it checked. Forget the natural ways of reducing it, till you get it checked.
Another possibility is a thyroid problem, which your PCP would be able to Diagnose and deal with.
Good Luck. ...Read more

Could you please tell me the proper way to measure recovery heart rate? Does duration of exercise matter? I was hoping to do it after 30mins of cardio.

Could you please tell me the proper way to measure recovery heart rate? Does duration of exercise matter? I was hoping to do it after 30mins of cardio.

Various ways: Count your pulse immediately after that exercise for 10 seconds and multiply by 6 for the end of exercise heart rate in beats per minute. Measure again in 1 minute and the rate should be at least 12 beats per minute less. In 2 minutes it should be at least 22 beats per minute less. The faster the heart rate goes down the better. Overheating and dehydration may keep pulse elevated. ...Read more
