|  The BretMetric, Systolic + 1.3 X pulse r  |
|  14 Feb 14 07:02:33  |
 From: bret.e.cahill@gmail.com After taking hundreds of readings waking up in bed in the morning I discovered I could reduce the systolic by ~ 20 mm Hg just by taking a deep breath and exhaling just above/before reaching the systolic pressure. This trick also ran my pulse rate up by ~ 15 points. I started adding the two unrelated numbers together to get something more resistant to fluctuation. So for years whenever I was in good enough shape to swim a mile in 30 minutes in surfing trunks the simple sum would ave. a solid 150. About a year ago I had problems with my neck and could no longer sprint. It's good to sprinkle a few intervals in to break the monotony of lap swim. Six months later the BretMetric went up 15 - 20 points for comparable swim times and it will not go back down, even as swim times approach 2 mph. Either the interval training is what really mattered or I've discovered a more efficient swimming style, the stiff neck not so free style. Consider the above a "text selfie."
