AY Honor Heart and Circulation
The Challenging Part
The most challenging requirement of this honor is probably this:
4. Record your resting pulse rate, then exercise strenuously (ie jog, swim laps, climb stairs, etc.) for 10 minutes. Retake your pulse immediately after exercising, and then again after five minutes. Do this each day for one week recording your results on a chart or a graph. Did the exercise affect your heart rate?
