본 연구는 좌업생활을 주로하는 70-78세의 비만노인 대상자 24명을 30분간 운동시간에 따른 각 걷기 속도(90, 95, 100,105,110,115,120,125, 130, 135,140, 145, 150bpm)별로 운동시간에서 각각의 걷기 속도에 의한 목표심박수를 설정하였으며 이를 운동시간별에서 각 걷기 속도에서 나타난 실제 운동강도와 예측된 운동강도를 요약하면 다음과 같다 1. 적정 운동지속시간과 운동강도에 따른 실제 측정 및 예측한 % 운동강도 운동지속시간 20분과 운동강도 40% 또는 55%이상을 운동강도 기준으로 보면, 20분에서 실제측정된 %예비심박수는 40%이상의 운동강도로 볼 때 120bpm, 125bpm, 130bpm, 135bpm, 140bpm, 145bpm의 속도에서 실제측정된 예비심박수는 41.2%~52.7%, 예측된 예비심박수는 41.7%~53.1%의 운동강도를 각각 유지하고 있으며, 55%의 운동 강도로 볼 때 150bpm의 속도에서 실제측정된 예비심박수는 57.0%의 수준을 보였다. 그리고 예측된 %예비심박수는 150bpm, 155bpm, 160bpm, 165bpm, 170bpm, 175bpm, 180bpm, 190bpm, 195bpm, 200bpm의 속도에서 55.0%~74.0%의 운동강도 수준을 보였다. 25분에서 실제측정된 %예비심박수는 40%의 운동강도 기준으로 볼 때 120bpm 125bpm, 130bpm, 135bpm, 140bm, 145bpm의 속도에서 44.7%~52.9%의 운동강도 수준을 나타냈으며, 55%의 운동강도 기준으로 볼 때 150bpm의 속도에서 56.4%의 수준을 보였다. 그리고 예측된 %예비심박수는 40%이상의 운동강도 기준으로 볼 때 115bpm, 120bpm, 125bpm, 130bpm, 135bpm, 140bpm의 속도에서 40.9%~52.7%의 운동강도를 유지하고 있으며, 55%의 운동강도 기준으로 볼 때 145bpm, 150bpm, 155bpm, 160bpm, 165bpm, 170bpm, 175bpm, 180bpm, 185bpm, 190bpm, 195bpm, 200bpm의 속도에서 55.0%~80.9%의 운동강도 수준을 나타냈다. 30분에서 실제 또는 예측된 %예비심박수는 40%이상의 운동강도 기준으로 볼 때 110bpm, 115bpm, 120bpm, 125bpm, 130bpm, 135bpm의 속도에서 실제 예비심박수는 41.0%~53.7%, 예측된 예비심박수는 57.0%~61.6%의 운 동강도 수준을 보였으며, 55%의 운동강도 기준으로 볼 때 140bpm, 145bpm, 150bpm의 운동속도에서 57.0%~ 61.6%의 운동강도 수준으로 보였다.

The purpose of this study was to establish the optimal target heart rate & % maximal heart rate reserve by each walking speed and exercise of duration, and predict relationship of target heart rate and exercise of duration, and %heart rate reserve and exercise of duration by each walking speed in obese older women. Twenty-four obese women subjects participated in walking exercise in place for 30minute at each walking cadence(90bpm, 95bpm, 100bpm, 105bpm, 110bpm, 115bpm, 120bpm, 125bpm, 130bpm, 135bpm, 140bpm, 145bpm, 150bpm), and the walking exercise in place was randomized using a balanced Latin Square. To order find out the most appropriate exercise intensity at each walking cadence was established & predicted intensity of 40% and 55% of heart rate reserve by Karvonen's formula. Statistical analysis was predicted regression analysis of each walking speed cadence & exercise of duration, and the Oneway AVOVA with repeated measures total target heart rate & % heart rate reserves by walking speed cadences were used to detect statistical difference. The result are as follow; 1. prediction & establishment at walking speed cadence and exercise of duration 1) The actual exercise intensity of 40% heart rate reserves was established as 110bpm, to 150bpm at a 20-mimute, 25-minute, and 30-minute walking, and of 55% heart rate reserves established as 150bpm but, the predicted exercise intensity of 55% heart rate reserves was 150bpm, to 200bpm. 2) The actual exercise intensity of 40% of heart rate reserves far an average of 30min during the walking was established as 120bpm to 150bpm at a 20-mimule, 25-minute, and 30-minute walking, but, the predicted exercise intensity of 40% heart rate reserves was established as 120bpm to 160bpm but of 55% heart rate reserves was established as 165bpm to 200bpm. 2. Changs of target heart rate & % heart rate reserve among walking speed cadence 1) Changs of target heart among walking speed cadence The results of Oneway ANOVA among total target heart rate of walking speed cadences & exercise of durations showed significant different among walking speed cadences(F=164.23, P<0.001). 2) Changs of % heart rate reserve among walking speed acdence The results of Oneway ANOVA among total % heart rate reserve & exercise of durations showed significant different among walking speed cadences(F=169.03, P<0.001).
