SYSTEM AND METHOD FOR DETERMINING A MEASURE OF THE PHYSICAL ACTIVITY OF AN OBJECT

摘要

The invention concerns a system and a method for calculating the physical activity level PAL as an objective measure of the physical activity of an object over a certain period of time. The system 1 comprises an activity monitor 2 having three orthogonally mounted accelerometers 4, 5 and 6 for measuring the acceleration of the object, data processing means 7 and memory means 8. The activity monitor 2 further comprises communication means 12 for communicating with calculating means 3 for calculating the PAL. According to the claimed method the calculating means use the following algorithm: PAL = factor 1 + factor 2astvariable 1 factor 3 + factor 4ast variable 2 factor5 + ... + factor 2nast variable n factor2n+1. Herein are variable 1 through variable n related to the object and/or the system and are factor 1 through factor 2n+1 to be determined by validation of the system.
