The HR talk got me wondering about resting HR so i measured it last night from when i went to bed at 11:30pm ( still being naughty, Skinny ) to when i woke for a 'wazz' at 4:30am.
There were 10 noticeable spikes in the middle 2 hours, with HR gradually climbing into the 90's (peaking at 99) and then dropping back, each one over a spell of 2-3 mins apart from one which lasted 10 minutes. I guess this is "deep sleep" and as such i find it interesting that HR spikes occur there as i'd expect this to be the period when the HR print is at it's flattest which isn't the case.
The average over the 5 hours sleep was 48 and the lowest was 37 so i guess i should count my resting HR as 37.
Other than for a bit of info/reading,the main point of all this is that my HR didn't reach the low of 37 until 2-3 hours ( when the spikes started) and in the 20 minutes before i woke up it gradually increased to low 40's. When i woke , it was low 50's ( i guess from the effort of leaning down and picking up my Garmin up off the table !! ) and then settled back to mid 40's which is what i've seen before when testing resting HR on waking.
So a potential difference of 8 beats per minute depending on which method you go by to determine resting HR.
Of course, most of you won't give a toss about this but it should definatley be of interest to Big as he may have his resting HR at the wrong mark for training, which could ultimately affect him when he's toeing the line and trying to bag a pb.
Sorry Lit. Madbee, Skinny , the childish twat in me couldn't resist
Good luck racers and parkrunners
