Question: I am a dedicated long-distance runner who keeps accurate logs of my runs - speed, distance and pulse rate. I get my heart beating at a rate of 140 to 160 during by runs. How long after I stop running should my heart rate drop and by how much? - F.N.

Answer: Within five minutes after your run, your pulse would be in the 100 to 120 range. If it isn't, you are probably doing something wrong. You may be training at too great an intensity or not allowing sufficient time between consecutive runs. I hope readers understand that heart rate per minute means the same as heart rate.

Answer: First, experiment with the various tensions and pedal speeds. When you are familiar with them, you can proceed to adjust both to the point where you can get your heart beating at or near your target heart rate. There are various ways to calculate this target rate. It is best to get a figure from your doctor after an exam. Your actual beginning exercise rate might be somewhat slower than that for starters. Work up to the target.
