Patent ID: 8092381

Claim:
A method for creating on a chart a personalized set of intensity zones of an individual, the method comprising: a. measuring blood lactate level of an individual while the individual exercises, and calculating therefrom a threshold heart rate corresponding to a lactic acid metabolic marker; b. determining an anchor point based on said threshold heart rate; c. providing: i. a computer readable memory for storage of said anchor point; and ii. a processor in communication with said memory that contains instructions that determine a heart rate range as a percentage of said anchor point for each of a plurality of heart rate intensity zones, wherein said heart rate range comprises an upper heart rate and a lower heart rate, and wherein one of said intensity zones comprises a threshold zone beyond which zones of higher intensity correspond to increases in said metabolic marker; d. determining a multiplier associated with each said intensity zone; and e. printing a chart comprising personalized information regarding said intensity zones and said anchor point.
