I have said elsewhere here that now I have got my HM out of the way, my "running" over the next couple of months will be only slow and easy. This morning I decided to try out a short experiment - nose breathing only while running. I have tried this previously and given it away very quickly - I really need to breathe through my mouth when running. But I am coming to realise that this is only because I am running too fast and it can be done with practice. Now - whether it is of benefit, I don't know - but there are plenty who say that it does have benefit. nomeatathlete.com/breathing...
So this morning I went out for a 20 minute run and determined that I would run it at a pace that allowed me to continue while breathing through my nose only. I actually started it at my front door and did not even do any warmup walk ( which I normally do to avoid the hill right outside) . The route I took was quite hilly so I wondered if I would be able to do it - but I did complete the task. And my pace was VERY slow - 8:30 mins per k. BUT- I was running and as soon as I stopped , I physically measured my heartrate by just counting my pulse for 15 seconds and multiplied by 4 - the result was 80BPM!!!! I couldn't really believe it and tomorrow I will do a parkrun doing this but wearing a HRM monitor.
I ran a hilly course for 20 minutes and my heart rate at the end was only 80 BPM!!!!!!!!
