Development and Validation of a Questionnaire for Health-Related Physical Fitness in Subjects with Low to Moderate Fitness Levels

適用於低至中等體適能程度者之健康體適能量表的發展與測試

摘要


本研究的主要目的為觀察不同類型的單次運動,對於中年受試者血糖吸收能力之即時影響。受試者分別進行45分鐘的游泳運動(1000公尺)或45分鐘的登山運動(昇高海拔約500公尺),在運動結束後一小時內,進行口服葡萄糖耐受度試驗。血液中的CK(creatine kinase)則於此單次運動三天後於空腹狀態下進行指尖採樣與分析。單次游泳運動對於空腹血糖值之影響不明顯,但對於這些中年受試者葡萄糖耐受度具明顯改善效果(在口服攝取75公克葡萄糖後的血糖值較前測低)。在登山運動方面,葡萄糖耐受度反而呈現相反效應,且血液CK濃度明顯因單次登山運動而增加(在攝取75公克葡萄糖後的血糖值較前測高)。已知運動訓練對於第二型糖尿病具有治療效果。本研究進一步顯示,對於中年受試者從事不同型態運動時,造成改善葡萄糖耐受度的即時效應有明顯差異。

It is generally known that physical inactivity is considered as a strong riskfactor for type Ⅱ diabetes.The current study investigated effect of different typeof acute exercise on glycemic control in middle age people.Twenty-onevolunteers were randomly assigned into two groups and performed eithermountaineering or swimming activities,respectively.A modified oral glucosetolerance test was performed before and 45minutes after the mountaineering orswimming activities under an overnight fasted condition.Blood creatine kinaselevel was measured before and three days after the activities.An acuteswimming produced little effect on fasting glucose level,but significantlyimprove glucose tolerance in these middle age subjects.Unlike swimming,mountaineering significantly attenuated glucose tolerance in untrained subjects.Mountaineering subjects display a significant elevation in blood creatine kinaselevel after the mountaineering activity.These results suggest that an acute boutof mountaineering could be detrimental on glycemic control to mid-agesedentary individual.It is known that exercise composes therapeutic effect totype Ⅱ diabetes.This study suggests that the mode of exercise is important forthe purpose of maintaining optimal glycemic control in middle age people.
