I try to walk 4 miles every day during the week plus hopefully something longer or some real trail miles on the weekends. At 61 years of age I have always wondered if I am pushing my heart rate too high. Today I took a hike up some local trails followed by a few miles around town. I brought along my wife's pulse/ox meter to take some readings.

While climbing some steep trail at a forced pace I measured 148-152 bpm and 95% ox sat. This was reassuring as my max heart rate calculation comes out to 220 - 61 = 159, so I'm in the right range there. Once down off the mountain I continued my workout on level surface streets around town. In an attempt to get a good cardio workout I aim for 14-15 minutes per mile and indeed my respiration is generally increased to the point of having to breath through my mouth. Taking my pulse after about a mile of this I got 82 bpm and 88% sat. I was totally surprised my heart rate was that low and the lower o2 saturation at that workout level. I generally have a high-ish at-rest heart rate around 75-78 bpm so I was hardly running higher that my at-rest norm.

I'm thinking that having a low-sh heart rate during a brisk walk is a good thing but I am still surprised it was that low. Does this seem normal to you all? I'd especially love to hear from someone in the medical field chime in.

Lower.......less stress. Sat measures level carried in blood. . It doesn't decide what is you sat.... A CO poisoned person can register 100% sat... But it's not O2. I take the USFS pack test every year, I'm 67.... Breath thru mouth. Not uncommon as you get more air .. never have measured bp tho... Personally I'd be happy with a low BP...
