PROBLEM TO BE SOLVED: To provide a muscle load monitoring device designed to notify a user readily and instantly whether or not his/her muscles are appropriately subjected to a load and prevent the muscles from being damaged unintendedly.SOLUTION: This muscle load monitoring device comprises: a characteristic value storage section 101 for storing characteristic values indicating physical characteristics of a subject a coefficient calculating section 103 which calculates the muscle coefficient of the subjects muscles to be monitored by using a standard formula stored in a standard formula storage section 102 as well as the characteristic values stored in the characteristic value storage section 101 a threshold value calculating section 105 which, by using the muscle coefficient calculated by the coefficient calculating section 103 and an muscle upper load limit value stored in an upper limit value storage section 104, calculates the upper limit muscle load potential corresponding to the muscle upper load limit value a comparing section 107 which compares the upper limit muscle load potential calculated by the threshold value calculating section 105 with the muscle load potential obtained by a measuring section 106 and a notifying section 108 which notifies the subject of the comparison results obtained by the comparing section 107.COPYRIGHT: (C)2013,JPO&INPIT【課題】筋負荷が適切であるか否かを、ユーザが容易かつ瞬時に知ることができ、また、意図しない筋肉損傷の発生を防止することができる、筋肉負荷監視装置を提供する。【解決手段】特徴値保持部101は、被験者の身体的特徴を示す特徴値を保持する。係数算出部103は、標準式保持部102が保持する標準式と、特徴値保持部101が保持する特徴値とに基づいて、被験者の監視対象筋肉の筋力係数を算出する。閾値算出部105は、係数算出部103が算出した筋力係数と上限保持部104が保持する筋負荷上限値とに基づいて、当該筋負荷上限値に対応する上限筋活動電位を算出する。比較部107は、閾値算出部105が算出した上限筋活動電位と、計測部106が取得した筋活動電位とを比較する。報知部108は、比較部107の比較結果を被験者に報知する。【選択図】図1
