Raising calculation precision, to calculate motion effective information more accurately it is possible this invention. In addition, offer of the living body information acquisition system and the living body information acquisition manner which can assure the degree of satisfactory improvement of the user is designated as purpose. As for living body information acquisition system 700, body composition total 707, before the exercising which was measured before the starting the motion acquires with the body composition data and after the motion ending after the exercising which was measured is the configuration which the body composition data. In addition, pedometer 505, is the configuration which acquires the vibrating data which is in the midst of exercising. In addition, it is possible to calculate the consumption calorie of user more accurately by having the consumption caloric calculation means (operation section 554 which calculates consumption calorie) which calculate consumption calorie making use of the consumption caloric amendment coefficient acquisition means (operation section 554 which runs step S816) and the said consumption caloric amendment coefficient which acquire consumption caloric amendment coefficient before the aforementioned exercising the body composition data and after the aforementioned exercising on the basis of the body composition data and the aforementioned vibrating data.この発明は、算出精度を高めて、運動効果情報をより正確に算出することができる。また、利用者の満足度向上を図ることができる生体情報取得システム及び生体情報取得方法の提供を目的とする。生体情報取得システム700は、体組成計707が、運動開始前に測定した運動前体組成データと運動終了後に測定した運動後体組成データとを取得する構成である。また、歩数計505が、運動中の振動データを取得する構成である。また、前記運動前体組成データと前記運動後体組成データと前記振動データに基づいて消費カロリー補正係数αを取得する消費カロリー補正係数取得手段(ステップS816を実行する演算部554)と、該消費カロリー補正係数αを用いて消費カロリーを算出する消費カロリー算出手段(消費カロリーを算出する演算部554)を備えたことにより、利用者の消費カロリーをより正確に算出することができる。
