Heart Rate for 60 minute swim at 9C (48F) in Serps 22 April 2012
One, two, three, four, tell the swimmers what he woreThe reasons for swimming with a heart rate monitor
Wed, 02 May 2012
Lately, I have taken to wearing a heart rate monitor (HRM) whilst swimming in open water. Questions ranged from the mild 'what is that' to the ridiculous... but let's not focus on the ridicule, moi indeed!
I use a heart rate monitor to assess the effort I make when training. I do not want to push my body beyond levels expected of a man in his late 40s, but I do want to know what sort of strain I put my heart under during each swim, especially when swimming in cold water and without a wetsuit naturally. The most important muscle in the body is obviously the heart and I want to understand what happens when I swim. I also want to use technology to check if I am doing too much, or conversely too little. I mostly train on my own, and the HRM helps me keep track of my actual swims rather than my perceived efforts.
I have attached the screengrab of my effort from 22 April in the Serpentine. The water was 9C (48F) and I maintained a steady beat of 57 strokes per minute for in excess of one hour. From my interpretation, the data shows that I worked between moderate and hard intensity. I did not overdo my training which is important. There are people with far more and better knowledge than me regarding how to use a HRM, but I'm learning.
If I played golf, I'd probably have purchased all the equipment, thankfully I'm an open water swimmer.
