Abstract
Disclosed are a method for measuring quantity of exercise and an apparatus comprising an acceleration sensor for generating acceleration information by measuring the quantity of exercise according to user movement, sensor control unit for supplying power to the acceleration sensor and sampling the acceleration information generated from the acceleration sensor, a dynamic energy measurement unit for converting the sampled acceleration information into dynamic energy, comparing a local maximum value with a predetermined threshold value if an ascending gradient of the dynamic energy has the local maximum value exceeding a predetermined value and determining a user step if the local maximum value exceeds the predetermined threshold value, a calorie consumption measurement unit for calculating calorie consumption by analyzing an energy level of dynamic energy determined as a user step, a memory for storing information, and a display section for displaying information related to the number of steps and calorie consumption.
