The present disclosure illustrates a method and a system for estimating an amount of exercise, which estimate the amount of exercise according to an exercise heart rate for an exerciser. Therefore, the exerciser can adjust an exercise mode or can execute the activity related to exercise based on the estimated amount of exercise, to reach the efficient and quantifiable exercise.本發明提供一種運動量評估方法及系統,其為根據運動者在運動時的運動心率來評估運動量。據此,運動者可根據評估後的運動量來調整運動方式,或是基於評估後的運動量進行運動相關的活動,以進一步達到有效且可量化的運動。100‧‧‧運動量評估系統110‧‧‧量測裝置120‧‧‧電子設備122‧‧‧運算處理單元124‧‧‧操作介面126‧‧‧儲存單元
