Soooooo, I like to do high intensity interval training at the gym about 2x a week. My normal method is to do about 30 seconds of high intensity, followed by 60-90 seconds of regular intensity (after a warmup) and repeat that cycle about 8 times, then a cooldown. I’ve never had any real problems with this despite my pulse going to 95% of max during some of the intervals.
Today I decided to try a different cycle which is 20 seconds of high intensity, 10 seconds of regular intensity and do 8 cycles of that. I figured my background in HIIT meant I was in aerobic shape to do this.
However after about the 5th cycle (only after about 2 minutes of HIIT cycles) I started to get a strange taste in my mouth, coughing, trouble taking a deep breath, chest pain, etc. Even when I cooled down and got my pulse down to what I normally try to get it to during my cool down period (during HIIT cycles I go for 90-95% of max, during cooldown I shoot for 70%) I still had the problem. After about 20 minutes it went away. Now over an hour later I just have mild coughing like I just recovered from bronchitis.
The last time I felt like this was in high school when they would make us run. Does anyone know what this condition is? Looking on google the only thing that seems remotely similar is EIPH (bleeding in the lungs due to intense exercise) but the info is mostly for horses.
I don’t understand why I’d have coughing and trouble taking a deep breath for about 10-20 minutes after I quit the intervals. Normally after a 5-7 minute cooldown (doing normal HIIT cycles) I mostly feel fine and I’ve never had trouble taking deep breaths, coughing, etc. due to HIIT. I’ve also never had issues with asthma before.
