Accurate Heart Rate Monitor watch needed!!?
August 25th, 2011
Can someone please provide a link or info to a heart rate monitor watch that calculates steps, calories and heart rate with entering in your height and weight? I have a Sportline watch that I bought at Walmart for 0 that doesnt require me entering in my height and weight and I am a little uncertain about the accuracy of the calories burned reading. It uses pulse technology.

New Exercise Bike with [possible] Screwy Meter Readings?
February 17th, 2011
My boyfriend and I recently got an exercise bike. We like it alright, though the resistance isn’t THAT great.
regardless, it has a pulse monitor on it. I saw that the first time i used it my pulse hit like 165.
the 3rd time my pulse went to 230 something.
my boyfriend used it and his did the same thing.
We’re questioning it’s accuracy. My friend said that once your pulse hits a certain point you lose aerobic efficiency.
My question is, does the bike sound like it’s reading accurately?
If it is, does that mean i’m losing aerobic efficiency?
How do you avoid having your pulse rate go that high?
is it dangerous to our health?

Possible sources of error in lab?
February 13th, 2011
This experiment was conducted to answer the question “What factors affect heart rate?”. In particular, this experiment endeavoured to find out the effect of mammalian diving reflex on heart rate. In this lab, a girl’s head was submerged in water. While she held her breath and stayed underwater for 20 seconds, her pulse was carefully monitored for any sudden decreases. The dependant variable was heart rate and the independent variable was time, measured in seconds. A heart rate monitor was used to increase accuracy. The girl was asked to repeat this procedure ten times, with the time interval between each “dive” being four minutes. Other constants include the temperature of water (5℃), air pressure, and the mass of the girl. Where could we have made an error?!
