when exercising, will i burn more fat with a Heart Rate of 130 or with a HR of 165?

Question

i know there are heart rate zones but do they actually make a difference?

Answer 1

You will burn more calories with a HR of 165. But if you are talking fat loss you will also burn more fat with a HR of 165. Note that your body greatly changes when you are exercising during fatigue. For example do a spin class and then run moderately for 30 minutes after you will see faster results.

You can get scientific but I won't bore you cause in reality it's get mathematics and doesn't work out. But in reality everyone is totally different. Take me for example I work out 6 days a week up to 9 sessions. I burn more body fat & weight during exercises that are high in intensity.

What you are asking is fat not weight so in theory the harder you train the bigger difference you will see so in essence the higher the heart rate the more fat you will burn.

Answer 2

Thats a very controversal question, and if done correctly both will almost produce the same results. Heres why. If someone is exercising at a heart rate of 130, they can withstand a longer duration then someone exercising at a heart rate of 165. (Excluding athletes) So 40 minutes at 130 is equalivant to 20 minutes at 165. Always do at least 20 minutes at target heart rate to get full results. Exercising at a higher heart rate is good for increasing your metabolism which therefore allows you to burn more calories throughout the day. Hiit cardio is also excellent for fat burning. That is where you do 30 secs or a minute at high intensity and then 30 secs to a minute at low intensity consecutively for 20 minutes. That blasts the fat. if you are a beginner though Hiit should be performed for a shorter time period.
Good luck

Answer 3

Good question, and one to which there are a number of possibilities.

First off, you need to make sure that you are exercising in a heart rate which is safe for you. A rough ball park figure can be got from subtracting your age from 220 and then multiplying that answer by 60% for your low end and 80-85% for your high end of your work zone. This is assuming you have no medical conditions which may affect your ability to exercise and are not taking any medication which may alter your base heart rate or blood pressure.

There is a more accurate and complicated formula - contact me if you want it.

The next consideration is your current level of exercise. If you're an absolute beginner, returner to exercise, or have been ill or injured, then stick with the lower end and build up from there. If you've been exercising regularly for a few months, then it's probably time to step things up a bit.

The reason that your low end of your exercise zone interms of heart rate is associated with fat burning (often calle the fat burning zone) is that it replicates conditions inside your body when food is scarce and your emergency fat stores are raided for energy. To get your body to use fat through exercise means you have to stay in this fat burning zone for at least 30mins - 45 is better. Your body will use fat as its primary fuel source for the activity.

However, as your body gets used to exercise, this response will become less activated. Your body will learn that you are not, in fact, starving, but are exercising. our fat is an EMERGENCY store, so the body will burn carbohydrates an d protein much more readily than fat. This means, over a few monts, you will burn less fat at the 60-70% of maximum heart rate. Coupled with a restricted diet, when carbs run out, your body is likely to break down muscle tissue for proteins, rather than use its cherished fat stores.

Stepping your exercise up to more intense bouts of 70-80% of maximal heart rate, then has some considerable advantages. While your body will not burn fat as a primary fuel, it will burn energy (calories) from any available source. This way, although the percentage of energy coming from fat is lower, the total ammount of energy you use at high intensity far outweighs the amount of energy used at 60% effort. Therefore, you actually burn more calories and more fat at a higher intensity - assuming you do at least 20-30 mins a day.

There is a further benefit - afterburn. Your metabolism is raised after exercising and will be running at a much higher rate and for longer after high intensity workouts. This means your body will be using more energy (calorie burning) after you have stopped exercising at a high intensity. Again - more total energy is being used, from all energy sources, so more total fat.

I hope this makes sense. Mail me for more info.

Answer 4

it depends how old you are.

The younger you are the more heart you need to burn fat, egg 18 is between 138 and 148

The older you get, a lower rate is then required to reach the same result.

You will loose more fat at 140, because you will be able to exercise longer, and burn more fat

Answer 5

OK heres the deal......

Heart rates that are lower the body will use stored fat as a source of energy but only with longer durations.

Heart rates that are higher then you will burn more calories, which ultimately means a more time saving, cardiovascular workout.

Basically try and aim for the second option..

Answer 6

Yes it really does. I have been excercising on my upper HR level , but end up with lower percentage of fat burn than when keeping around 120 (my lower level HR). That usually leads to 50% fatburn. This has led me to walk fast on the threadmill (tilted to 7) and a speed of 6-6.5. If I run the same time instead of walking my fatburn drops dramatically but I burn more calories.

Answer 7

The higher heart rate will train your cardiovascular endurance.
The lower heart rate will burn more fat because you maintain that steady accelerated heart rate for longer periods of time.

Answer 8

depends on you age, current weight, body type, present metabolism. speak to someone who is qualified . usually, 65-70 % of your maximum heart rate burns more fat calories. this is calculated by subtracting your age from 220, then Multiply the answer by 65 %....this will calculate what 65 % of your max .heart rate is...fatburning zone!

Answer 9

Stick to an even more low fat protein/green plant diet regime

Answer 10

have a 30 minute split in the heart of ones meal consider exactly how starving an individual still are generally just before receiving to the food
