All-out sprinting and Max HR

[Guest guest]

I did some " all-out " sprinting uphill 5 x 1 minute with 2 minutes walking

down the hill in between. After the third sprint my heart rate

monitor showed a " modest " 238bpm. Is this possible?

I would get my heart rate monitor checked.

Absolutely. I've seen 216 on my HR monitor (confirmed roughly by

finger-on-wrist) on multiple occasions in weight training, and I'm 46

years old.

Ali & Wayne, Get Harvey 'big bud " Maron to verify this -- 238 is too high for

training -- possibilities of fibrillation?. (overkill to its extreme)

Try this for Hill/dune sprints. (dune sprints may? be even more taxing? vary

surfaces and inclinations as possible)

2 sec's accelerate, then *10* secs (NOT 60 SEC's) max effort -- walk/slide

back to bottom of hill dune, walk around a bit and see how high heart rate

gets -- when it returns to 115-120, repeat 5-6 times.

I'm not sure training past max predictable, by age, heart rate is beneficial

on a " regular? " basis. Add seconds to 10 as needed. Never more than 20?

depending on goals, training history, neural efficiency and fiber type?!

I know this isn't the kind of info people want to see on a health and

fitness list, but bear with me. I was recklessly experimental in

high school, and I once tried freebasing cocaine. My heart started

beating so fast that it really frightened and concerned me, so I took

my pulse several times. The readings were consistently well over

200, some near 250, and this lasted for around 10 minutes or so. I

was only about 16, though. As far as I know, the incident caused no

permanent damage. So, in my experience, such heart rates are

definitely humanly possible.

Incidentally, the stereotypical scare info about smoking

crack/cocaine was all true: in the following hours I felt super-cool

and superior to others, was rude to my friends, and despite the scare

I desperately wanted to do it again. Fortunately, I had no real

access to the stuff and never did. Given the addiction potential and

the likelihood that I could have died if my heart wasn't perfectly

healthy, I would now definitely classify it as something too

dangerous to even experiment with.

Sorry I did not pick this up. Sprinting is not one of my interests and

with time always an isssue I did not follow this thread..

Jerry is 100% on the mark. 238 is much too high and is certainly not

normal. I would see an M.D. to set up ambulatory ECG monitoring and

capture the event on tape.

I would not delay since results could be serious.

,

Thanks for your post. I hope that kids will see it and realize that

some things you try (cocaine included) can kill you the first time.

I think many people try to tell youngsters that they can do drugs

once and it's okay.

Thanks,

Yes 238 bpm is 'humanly' possible but I am skeptical about it being achieved via

normal healthy exercise. 238 is roughly 4 beats per seconds, now think back, do

you recall your heart making four full beats each second? Technically I think

238 might be considered some form of cardiac arrest.

I have a form of SVT, super ventricular tachycardia. Basically my heart will

take off beating like a mofo for no apparent reason. I have been clocked by ER

staff on sophisticated monitoring equipment in excess of 225. At this rate I

could not detect any discernable separate heartbeats, it was more like a snare

drum doing a drum roll - very fast beats that all ran together. I, by the way,

was not breathing hard, as you do when you are in oxygen debt, but rather felt a

great heavy invisible pressure on my chest.

This has happened only four times in my life, twice when I was in my teens and

twice during my late 30's, I am 40 now. The episodes in my teens I just laid on

the couch and marveled at my heart rate until it slowed down to normal, around

20 minutes later. The episodes during my 30's my heart was still beating hard

after 45 minutes with no signs of stopping so I called 911 per my doctor's

orders and the paramedics came and gave me a chemical form of defibulation

called Idenicard. The Idenicard is a real trip because it is basically designed

to stop your heart, i.e. go from 238 to 0 in about 1 second. Your heart then

rebounds and starts to climb back up but (hopefully) stabilizes you somewhere

much lower than where you were at before (and you feel loads better).

Anyway, not to bore you with my medical history, but I give you this

backgrounder because I would have to say that based on my experience I would

think a 'normal' exercise induced, oxygen debt replacing type heartbeat just

could not pound that fast that fully. I could be wrong though.

Once when I was 40 with a theoretical max HR of 180 ( I beleive that's correct)

I was jogging with a HR monitor on a mountain trail. While resting and fully

recovered with HR less then 70, my dogs started chasing a momma bear with 2 cubs

(very dangerous, as they sometimes will chase the dogs back to you). Well

anyway, its not often one has opportunity to observe their own HR under such

stimulating circumstances, and yes it almost maxed out at over 175 with only a

slight accelerated respiratory rate. At that no point there was no resumption

of exertion. I found that interesting as I'm not a high level aerobic athlete,

and would have had difficulty exercising hard enough to hold or even achieve a

max HR like that.

Telle--

Your heart rate, in all likelihood, was mental/emotional(adrenalin?) induced

--- much like a race car driver's or basketballl coach's? *Not* a recommended

method!

I suggest you tie your dogs to a tree and you gently --while monitoring heart

rate --chase the cubs (or not).
