Comments on: Does elevating your heart rate during exercise have the same effect on you as a fight or flight response?

I’ve been working out for years (age 21), and have recently taken a few months off to recover from an injury. when i returned to the gym with my buddy, we continued at our regular rate, and after some fairly intense cardio mixed with push-ups, i felt progressively dizzy and experienced tunnel-vision with a loss of balance. i didn’t check my heart-rate after the workout, so i can’t be sure if it was simply being too far over my limit, but it certainly has never happened before. i went and sat down, putting a cold wet cloth on the back of my neck (thanks to a concerned gym-goer) and soon cooled off enough to continue with weights. the sudden worsening of what i was feeling may have been contributed to by my feeling that i may have pushed my heart too far and possibly put my life in danger, but i’m curious to know if this is fight-or-flight, overexertion or a mix of both?

(for the record, i start basic training for the military soon, so i’ve been trying to get as much cardio as i can)

I am 46 and while riding a bike 2-3 times a week my HR averages 174 for a 1 hour run (which tires me but doesn’t kill me). I am not a regular exerciser. 10 years ago, I got it up to 208 during a stress test and the cardiologist said I just needed to exercise more regularly. Had another ST and it was 196 a year ago and again doctor said nothing wrong with EKG or anything else, just higher than NORMAL people. Please ’splain Lucy!

I am a 17 yr 8 month girl distance runner. I train year round and run between 45-50 miles per week in the summer. I run about 40 miles per week during racing season and alternate hard runs (tempo, intervals) with easy run/ recovery days. During my hard run days, like today, I have noticed that my heart rate will increase to around 180-183. I was running 6 x 1000 m at race pace. After the first two 1000’s, my heart rate was around 182 bpm at the end of each 1000. During the next four 1000’s, which I ran just a few seconds slower, my heart rate actually dropped in #3 & 4 to around 178 at the end. And during my last two, my heart rate did not get over 176, but I was totally exhausted and my perceived exertion was 100%. I don’t understand why my heart rate wouldn’t continue to rise as my effort increases and I get progressively more tired.
thoughts?
