Once over the top, the runner should jog slowly down, then go up again, and repeat as many times as desired. Each training method helps runners in a different way. When using various training aids together, independent information can be fused to provide a much clearer picture of each training event. Comparing velocity, position and heart rate can make workouts much more effective. Nothing satisfies a coach and runner more than knowing the runner has trained harder and more effectively then ever before.
Many people use heart monitors to measure how hard their hearts are working.
The monitors usually consist of a chest belt and a special watch unit. Body weight and resting heart rate help determine a person's maximum heart rate. Most people's maximum rate is around 190 beats a minute. Most runners can race only within 90 percent of their maximum heart rate, and a very few of the world's top runners can race at 95 percent of their maximum. Many amateur and intermediate runners have problems with their perception of the difficulty of their current workout.
