The lead tutor/nurse on the Cardiac Rehabilitation programme that I am attending quizzed us on exercise. It seems that going for a dander, a stroll or even a long walk, whilst still important, might not count as exercise.
I now have a new refrain sounding often in my mind - “activity isn’t exercise”.
“If exercise is the medicine” the nurse continued, “then what is the dose?” The answer will , as is often the case, “it depends.” This is because we are all different and with different types and degrees of health challenges.
I walk often, nearly always with Una. We cover quite a bit of ground (6 month daily average steps). Sometimes we walk at a decent pace sometimes it’s a stroll. For heart health I need to up my game. When walking I’ve to get my heart rate up (between 87 and 110 bpm - ) and I’ve to be slightly more breathless though yet still able to have a conversation.
And I’ve done that this past week. Delightedly so - there were no heart rate spikes on those walks. There have been spikes of course. These were on very simple and short walks. There has been some fatigue as well. Friday afternoon I was so, so tired. Had to have a late afternoon nap.
Yesterday I had some “angina” type symptoms just sitting still (more on that another time). Decided to go for a walk anyhow. Mistake. There were spikes aplenty. Or perhaps one prolonged event, can’t be sure. We were out for an hour and there were hills. Getting back home was quite the test.
We’ll walk again today - carefully (a more level route definitely). I refuse to sit in my armchair and watch the world go by.
I’m working out how I answer the dosage question. How hard should I push? How often and for how long? Back at the Cardiac Rehab tomorrow. I’ll report all these goings on and ask how I might best calculate my personal dosage.
Let me leave you with a question. When and how often do you get your heart rate up? To that level where it constitutes exercise? Safely?
Worth looking into folks
