Is my heart rate monitor watch accurate for the number of calories burned?

Is my heart rate monitor watch accurate for the number of calories burned?

Not really: Calories burned depends somewhat on overall conditioning, weight, and other factors that can't be measured by heart rate alone. However, it is good for judging a relative amount of calorie use, and to give idea of how long it will take to burn off that slice of chocolate cake you had for dessert! ...Read more

Is the rate at which you burn calories dependent on how fast your heart beats, will medication that makes your heart rate increase burn more calories?

Is the rate at which you burn calories dependent on how fast your heart beats, will medication that makes your heart rate increase burn more calories?

Not dependent on hr: not a bit no. For that matter diet pills that induce significant weight loss do not significantly raise metabolism. ( I try for 1000 calories out per day; studies showing m a y b e a tenth of that with drug induced metabolic effects are what I mean by NOT significant). but changing thoughts/ behaviors help. http://www.amazon.com/dp/0692496157/ ...Read more

I have a 57 RHR. I workout 3-4 times per week and struggle to get my heart rate into an aerobic zone. I try to burn 600 calories per workout but per heart rate monitor it takes 1:30 hours. With Bradycardia is heart rate indicative of calorie burn?

Doing good: Please do not obsess about heart rate and calories burnt. If you maintain a healthy weight and exercise 150 minutes/week you are doing great. Over exercising may not be a good idea. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

What should my target heart rate to burn fat?

What should my target heart rate to burn fat?

Ignore pop wisdom: Nobody's going to exercise scientifically for weight loss. It's a fact of human nature. Instead, you owe it to yourself to find something at least moderately strenuous that your physician approves, that you like, and that you can do with friends. Go crazy doing it, and get high from it. This "best heart rate" stuff is window dressing. Go get fit and have a great time doing it. ...Read more

Does ones metabolism slow down in eating 1000 calories per day?

Does ones metabolism slow down in eating 1000 calories per day?

Yes, but...: If you eat less, your metabolism slows some. But it is not that much. It doesn't go down to zero. You still need to pump blood and breath. Exercise can diminish some of the slowing of metabolism. On the flip, when you overeat, your metabolism speeds up as your body attempts to dissipate the excess calories. ...Read more

What's your resting heart rate like just after 70% max heart rate from exercise?

What's your resting heart rate like just after 70% max heart rate from exercise?

Trick Question?: Well... If you just finished exercise at 70% pmhr, your hr is... (drumroll)... 70% pmhr. Now if you're asking about recovery, hr will generally decline to 50% pmhr within 5 minutes for most people, though it depends heavily on whether you had an anaerobic component in there too. ...Read more

I just made 35 push-ups, and my heart rate sky-rocketed to 198 bpm. Is this heart rate too fast, for that exercise intensity?

I just made 35 push-ups, and my heart rate sky-rocketed to 198 bpm. Is this heart rate too fast, for that exercise intensity?

Out of shape: If accurate, HR 198 is high and possibly related to exercise intensity in someone out of shape. Start training in an exercise program using aerobics first and than add push ups and weights. You did not tell me the age but if you are over 35-40 and overweight you should clear the exercise program with your physician ...Read more

Can exceeding your target heart rate during aerobics have a detrimental effect on muscle gain and fat loss?

Can exceeding your target heart rate during aerobics have a detrimental effect on muscle gain and fat loss?

Target zones: For fat loss 70-75% of maximal heart rate for 45 to 60 min is good. For endurance, without loosing muscle mass, 85-90% or more with 1-2 mins sustain, then slowing down to 60-70% resting. Alternating resting and bursting for no more than 30min total. You can, with time, increase burst time and decrease resting time as you get in better shape. 3 times a week with weight lift and increase protein. ...Read more

Medically supervised very low calorie diet (800 calories). Ok to exercise. Principle of ketosis. Burn about 400 cal/day/hr monitor. Safe?

Medically supervised very low calorie diet (800 calories). Ok to exercise. Principle of ketosis. Burn about 400 cal/day/hr monitor. Safe?

No safe shortcuts: This type of diet often makes the body angry, decreasing calories too much too quickly will send your body into starvation mode. Less calories = weight loss, but your body will become more efficient at holding onto calories, so you will gain the weight back and then some later on. Weight watchers is the safest and most consistent in my experience with thousands of people. ...Read more

Went back to gym. .5 miles on treadmill 90 calories burned. Told not to get my heart rate over 161. Between 120-161 normal? Is that ok

Went back to gym.  .5 miles on treadmill  90 calories burned.  Told not to get my heart rate over 161.    Between 120-161 normal? Is that ok

Yes OK after workout: When you work out, your heart rate will be higher than normal for a several minutes as your heart beat begins to normalize down again to baseline. If it was this high all the time, even at resting, you would be in trouble. So follow your doctor's advice, and stay healthy, work out, and exercise. It's good medicine! ...Read more

What to do if heart rate v sweat which is a better measurement for calorie burn up?

What to do if heart rate v sweat which is a better measurement for calorie burn up?

Heart rate: Consider this: you exercise at 85% of your maximum predicted HR for 30 minutes and burn up X calories (depends on your age, weight, sex). Versus-you sit at your desk for 30 minutes in 85° temperature pouring off sweat, burning 0 (or very few) calories. Heart rate wins because it is more directly proportional to your muscular work. (at least, that's my opinion). But it's a GOOD question!! ...Read more

Are you burning muscle if you go above your target heart rate?

Are you burning muscle if you go above your target heart rate?

No: There is no such thing as "target heart rate." depending on your training goals, the "target" could be anything from 60% to 100% of your max heart rate. Exceeding ~80-84% of max heart rate shifts metabolism to anaerobic (airless) metabolism resulting in the production of Lactic Acid and the burning sensation. The body is burning pure glucose here. Muscles break from overuse, not that process. ...Read more

Not necessary: I assume you are talking abou your maximum calculated hr. If thats the case, not necessary. Depend how long you stay there. With high protein diet, weight lifting and short burst 1-2 mins every 5 mins of fast running for no more than 30mins, 3 times a week, probably not. Every person is different but you will built endurance and cardiac capacity. Check with a trainer for better results. ...Read more
