マスターズ女性長距離ランナーの呼吸循環機能に及ぼす年齢及び閉経の影響

This study sought to determine whether the ability to cardiorespiratory endurance is affects by age and menopausal status. Subjects were forty-two trained middle-aged women endurance runners (average training history=11.9±5.3 yr.) from ages of 33 to 68 yr. (average age=51.0±8.8 yr.) were tested on treadmill to examine physiological responses (Vo_2max and Vo_2 at ventilation threshold). Although 1) Vo_2max and Vo_2 at ventilation threshold was lower with age. The younger runners group (-39 and 40-49 yr.) had significantly higher Vo_2max than other two age group (50-59 and 60- yr.). 2) Maximal heart rate did not differ across age group, but HR at ventilation threshold was lower in age over sixty group. 3) Menopausal status in middle-aged women distance runners were not significantly different on any exercise physiological variable when with age. 4) A decrease in Vo_2max of 0.45ml・min ^^・kg^・yr. was determined. These findings suggested that the ability alter cardiorespiratory endurance (Vo_2max) in middle-age women runners is effect of age, but not of menopausal status
