title says it all. is there a diffrence between burning fat and carido heart rate. like for instance if your rate is 90 is it better for burning fat than say 140-150

BEETROOT

yes, you burn a higher percent of calories from fat at a lower heart rate (60-65% of max). you burn more calories overall (and more from fat, but at a lower % vs. total) at a higher rate (80-85%), but you won't be able to keep up that rate as long.

a rate of 90 won't do jack. there are certain formulas to determine where your target heart rates should be (try google), but in general I shoot for between 130-150 for low intensity.

90 HPM won't do anything. Beetroot is correct, 60-65% of max -- typically calculated as 220 minus your age -- is the best for burning fat, so for you, a HR of 118-127 would be best. If you're in better shape, you can increase that.

i was just usen that number off the top of my head. so you could get the idea of what i was talkign about.. but thanx for the info i try to keep my heart rate anywhere from 130-150 is that to high for burning fat?

BEETROOT

depends on the shape you are in, but thats a good ballpark number.

try this:

220 - (age + resting HR) = y

y * .65 (65% = HR for fat burning)

+ (resting HR) = highest HR for fat burning



so for me:

220 - (25 + 55) = 140

140 * .65 = 91

91 + 55 = 146


So basically anything less than 146 would be considered low intensity, anything above high intensity.

my heart rate approaches 190 when im running. its that really bad? ive seen it get to the mid 180s a few times

BEETROOT

I don't think its bad. A guy I used to run with would be in the 180's when I was at 160 or so and he was in perfect health.

Also a few factors to consider - Is it up that high just from jogging or is that from a sprint? What kind of shape are you in? How old are you? Are you new to running?

Beelzebub

Not really.

Also you max HR is a absolute, and it doesn't go by the formula.

In an intense period I can get to 190. (although it feels like my heart will explode)

Take into account that I am 35 and a resting HR of around 40. and right after I wake up it is in the low 30s.

I have had paramedics ask me unusual questions on some of my rides in ambulances.

BEETROOT

are you an ex (or current) road biker? how did you get your resting rate so low?

Beelzebub

Current rodie. (with some mountain biking thrown in, for variety)

Before I started road riding almost 14 years ago my resting pulse was around 65.

I also have problems donating blood, as it is below the minimum that they will take(45)

BEETROOT

Thats incredible. Mine is about 55 and I get comments on it when I've had it checked.

Minch00

Mine is 80? Is that bad?


And my average heart rate is like........150-170 depending on what I'm doing when I'm working out. I've seen 200s before, during like full sprints and things of that nature.

Jaydef03

i hit 185 in a heavy jog, maybe 7.5 mph. im 21, 200 pnds

Jaydef03

sooooo umm can having to high of a heart rate kill you?

Whiskers

If you are working out and your heart rate goes too high (200-250??) then you can go into cardiac arrest.

JJ4Short

Hmmm makes me want to buy a heart monitor watch, because sometimes I work myself to the brink of passing out.

Whiskers

You should absolutely get one. I got a Nike one, which works fine.

BEETROOT

No, thats not bad. As you continue to do cardio over time you will see it come down.

Jaydef03

heart arrest at 200? ive hit 200 before and i wasnt even running, but that was back when i was taking ephedra free (stacker*) type pills.

Whiskers

I put question marks on that cause I not too sure. If you are unhealthy then 200 may kill you. If you are fit then maybe 300...
