Anyone know of a HRM that will alert you while actually swimming (not when standing in shallow end) if you go above or below your target zone? The Mio Fuse? I can't find a good review of someone swimming with it. All the other HRMs seem to need to be out of the water to send readings from the chest strap to the watch and have audible alarms that I know I wouldn't hear while swimming anyway.
I always thought that the target was calculated by getting the max (220 - age) and then taking the percentage from that (such as 85%). Also it's been proven that your HR would be lower in the water than land because the water pressure and the lack of having to fight gravity since when you're swimming, you're usually prone instead of standing.
I'm using the fat burning range described in Christopher McDougall's new book. It works out to 71% - 77% of your formula. The American Heart Association recommends training within 50% -85% of your formula, so it's in the range, but supposedly in the using fat for fuel range. The point is, a 10 bpm zone is tough to stay in.
As for swimming bpm's, I found the following on aquatic deductions from a Swimovate manual for heart rate training:
for a 40 year oldMaximum heart rate on dry land = 220 – age = 180 bpmHeart rate when standing out of pool = 101 bpmHeart rate when armpit deep in pool = 90 bpmAquatic deduction = 101 – 90 = 11 bpmMaximum heart rate in the pool = 220 – age – aquaticdeduction = 220 – 40 – 11 = 169 bpm
