Interval Training Question

Perple Gyrl - 27 Feb 2004 05:29 GMT
I started doing interval training on the elliptical for 30 mins at a
stretch.  I do 2 mins on level ten then 2 mins on level 2 for recovery.
Here is my question... Should I be in cardiovascular mode during the high
intensity and fat burning mode during recovery?  I currently aim to hit a
heart rate of about 140-145 during the high intensity 2 mins, then drop to
125-130 during the recovery.  Is this a good level or should I opt for
different heart rates for optimal benefits?

I also switch around and use the treadmill and recumbant bike for variety,
but do not do interval on them.  When I use the bike, I use it in hill mode.
When I use the treadmill, I do vary my walking pace from 2.5-3.5 and my
incline from 5%-10%.

Thanks!!

284/210/199/???

Another plateau *sigh*
I am hopefully building muscle to compensate for stagnant numbers!

You'll probably get other opinions, but I personally don't put much
stock in the "cardiovascular mode" vs. "fat burning mode" ranges that
you see posted.  When I do intervals, I just aim for a period of
intense effort followed by a moderate-effort recovery.  Your heart
rate numbers sound reasonable to me, though I think perhaps you could
work up gradually to a little bit higher numbers during the
high-intensity period -- maybe for a shorter time.  There are all
sorts of good ways to do interval training.

I'm going to agree with Chris on all of this.

For me, a heart rate of 140 is a light workout.   My intensity
intervals, I'll get my heart rate up over 160 and hold it for a while,
then back off, and when it returns to about 125 then I'll do it again.

One thing I found over a period of time doing intervals is that the
recovery period is much shorter.   As in, I can do high intensity and
then cool it down a bit, and find that my heart rate drops to 120
quicker over time.

Thanks guys!  I'll keep your suggestions in mind!

JayJay... my elliptical trainer puts a heart rate over 150 for my age group
in the "danger" zone.  I try not to get that high....

I'm sure age and weight differences could make a difference.   I
forget that not everyone is my age and weight and fitness level.   :-)

whereas I'm 32 and 130.   I've also got low cholesterol and no health
problems.   So, I know I can strain my heart pretty good.

For me, I don't really monitor my heart rate when I exercise.   I just
go until I *feel* maxed out, then I back off a bit.   While on
vacation the machines had the heart rate monitors, so I'd check them
out just to see.   On rare occasions I'll take my pulse during
exercise.    

I don't fret over numbers that much.  Exercise isn't like that for me.

To give another example:  Tom's ex-fiancee, who is 24 and was captain
of a division one lacrosse team in college, will get her heart rate up
to 200-210 on high-intensity intervals.  Not something I'd ever try,
but it works for her.  Tom (26) will get up into the 180-190 range
when he does high-intensity work.

What about what I've heard about staying at 65-70% to burn fat?

I think you can ignore that.  Tom tells me that those numbers are (a)
"cover-your-a.s cautious", and (b) not aimed at people who are more
fit.  I don't recall how old you are, but I'm 55 (56 soon) and
routinely get up in the 160 range when I do intervals.  But I worked
up to it -- didn't do that my first time on a treadmill :-).

Ok thanks Chris... Just wondering why I heard to stay at  65-70% to burn fat
then... are those percentages not accurate either?

I think most people I've talked to think the whole "fat burning range"
thing is bogus.  I'd just ignore it if I were you.

Really?!  All this time I've thought opposite and tried to purposely keep my
heart rate down.... I'll try to go higher and see if that helps me more.

I think there's quite a bit of consensus that doing intervals with
significantly more exertion is better for weight loss.  And there's no
question that it's better for exercising your heart and improving your
endurance, which are important goals for exercise independent of
weight loss.  So go for it :-).

From my understanding, long term exerution of the high heart rates
will cause muscle loss over fat loss.   Usually those people will
report smelling amonia or other odd odors from their sweat.

But, like Chris said, the general consensus is that interval training
where you get your heart rate up high and hold that for a couple mins
at a time, will be more beneficial for weight loss and cardio fitness.

150 = danger zone?  Only if you're 100 yrs old.  For me, "easy" day
workouts are at 135 pulse to 140.  Hard days 150 to 160.  9 to 10
minute miles are "easy", 7.5 to 8.5 min mules are "hard." If I did
intervals, I'd try to get to my max hr rate, 167, during the
intervals. I'm male, 55 years old.  Females, your max hr rate is 225
minus your age (approx).  During intervals, you should try for an
intensity that feels very, very, hard - so that you can't wait for the
minute (or two) to be over.  The principle of training is simple - you
must overload your system to improve.  Overload means doing more than
you are used to doing. You should alternate hard and easy days.  Do
easy days at least until you no longer feel sore.  For excellent
advice on training check out www.drmirkin.com and also look into his
latest book.

I think you received some pretty good responses to this so far.  One thing I
do when doing intervals is to spend a few minutes 3-4 at pace where I'm
working enough to breathe a little heavy but I can still talk, then I'll do
a 1-2 minute sprint which my workout pals and I refer to as "balls to the
wall" meaning it's tough enough that I probably couldn't keep it up any
longer.

For example with running on the treadmill I might go steady at 6.5-6.6 mph
which is work, but I can keep it up for at least a half hour or longer if I
had to.  My sprint interval is up to 8.4 mph and I can hold it for about 2
minutes, then I absolutely have to slow down.  The sprints used to barely be
over 7 mph but they're getting better.  I don't know my HR when running most
of the time because I don't want to slow down or stop long enough to do it
and I can't do even at 6.5 mph because I have trouble finding my pulse most
of the time.

On the elliptical I do a pyramid pattern starting at level 12 for 5 min @
70-75 rpm and move up a level every 5 min until level 15.  Every 3rd
interval I do backwards and I sprint the 4th minute at whatever level I'm on
which increases the rpms to 90-100.  My HR is generally between 140-150 and
then gets a little over 150 during the sprint.  I've tried to get it higher
just to see if I can, but my leg muscles give out before that happens.

I've heard that the "fat burning" interval level is crap but I don't have
anything to back it up one way or another.  I just shoot for keeping the HR
at 75% of max when doing anything but running.  I don't really care what my
HR is when I run, I only care about how much distance I can cover and/or how
fast I can do it.

Cool... I'll try that.  I've worked myself up to level 10 for an extended
amount of time.... I've just always heard that you need to be 65-75% for
maximum fat burning... Its a bit confusing.  Of course, I want to obtain
optimal numbers!

I guess that interval training is a different training
tecnique.
Some studies seem to show that interval training works better for fat
burning purposes than staying in the fat burning range.
I actually do both trainings.
I jog for about one hour, then I do some exercises of interval
training (not every day, because I do not ever feel like doing it).
I run fast for 100 meters, then walk for 100 meters, then again.
The whole "thing" is only 5-6 minutes long at present, but it should
be about 20 minutes long for trained people, I suppose.
Refer to Krista's site for reference.

Krista refers to it as "fartleks".

I also do interval training.  I call it "high intensity interval
training" or "HIIT" for short.  I do it once or twice a week.  The
sessions are necessarily short (if you can do long then you aren't doing
high enough intensity) but they are good for stimulating my metabolism
so that I burn fat more easily.

My sessions are typically 20 to 25 minutes long, where I start out at a
warm-up for 4 or 5 minutes and then do a sprint for a minute, then
recover for a minute, then build back up my pace for two more minutes
and sprint again.  I usually do about four sprints every four minutes or
so then warm down again and I'm done.  I like the workout because it's
so brief to do.  I usually do it on my NordicTrack at home.

That's a running term used for decades. Check out www.runnersworld.com for
