This means that the higher speed of movement, the greater the number of beats per minute reaching the limit (estimated at 220 minus age for men and 200 minus age for women).

Regarding metabolism can be based on the concept that it requires about 70 calories per kilometer race (always depending on the intensity), so if you make your calorie count, you can discern how to remove excess run. For example, if you have entered 2200 calories and has run 7 kilometers, has used its reserves to 300 calories, and required 2000 for basal metabolism and 500 to run that distance.
