高齢者における運動に対する呼吸・循環応答の特性を明らかにすることは、運動処方を作成する上で非常に重要であると考えられる。先行研究では、運動時の酸素摂取量の立ち上がりは、若者に比べ高齢者では遅れることが報告されているが、運動開始直後15秒以内に見られる換気や心拍数の急増(Phase I)に関して、高齢者と若者を比較した研究はこれまで行われていない。そこで本研究では、運動開始20秒内での高齢者の呼吸・循環応答を明らかにすることを目的として実験を行った。被検者は60才以上の高齢者12名と、比較群として健康な成人男子20才台の若者12名で、1)騎座姿勢で体重の約5%の重りを足首に装着し、安静状態から随意による両脚交互の伸展-屈曲動作を1秒/回のテンポで20秒間行わせる随意運動、2)安静状態の被検者に対し、同じような動作になるように、検者が被検者の脚を受動的に引っ張る受動作用を20秒間、それぞれ12回行わせ、その時の換気量や吸気ガス濃度をbreath-by-breathで、また、心拍数、インピーダンス法による心拍出量、トノメトリ法による血圧をbeat-by-beatで測定した。その結果、高齢者は、随意運動および受動作動開始直後の換気増大分が、若者に比べ有意に低いことが明らかとなった。高齢者の中には運動時に換気が安静時よりも低下したり、運動中全く無呼吸になるなど、呼吸が抑制される場合も見られた。また、心拍数や心拍出量については、高齢者の立ち上がりは若者と比べ遅い傾向が見られた。血圧は高齢者、若者とも運動開始20秒以内には顕著な変化を示さなかった。このことから、高齢者は若者に比べ運動開始直後の呼吸・循環応答が低く、運動に対する適応が遅延する傾向を持つことが明らかとなった。従って、高齢者に運動処方を行う場合、これらに留意し、ゆるやかに運動を始める必要があることが示唆された。

People with high levels of health care are required to respond to the characteristics of the information system, and the participants are required to make sure that the information is very important. First of all, we should study the amount of acid in the first place, and then take the amount of acid in the first place. If it is higher than that, we should make a report on it. The number of heart beats within 15 seconds after the start of the exercise should be monitored. The number of heart beats (Phase I) will be very high. If you are more likely to do so, we will do more research. In the first 20 seconds of the beginning of this study and exercise, the breathing of those who were high-level should be informed that the purpose of this study was to improve the performance of the students. There were 12 men who were over 60 years old, 12 men who were over 60 years old, 12 men who were 20 years old than those who were healthy, and 12 men who were 20 years old. 1) the posture, weight, foot, foot In the same period of time, the exercise time was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the clock time was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, the time limit was 12 seconds, the time limit was 20 seconds, The results of the test, those who are in high school, and those who are free to participate in the exercise will have a large score immediately after the start of the activity. if it is lower than the intention to do so, they will be aware of the situation. In the middle of the exercise cycle, when the person with high altitude is in the middle of the exercise, when the exercise is quiet, the alarm is low, the breath is full, and the breath is suppressed. The number of heart beats, the number of beats, the number of beats. For those with high blood pressure, if the person is busy within 20 seconds of the start of the exercise, he or she will show his or her health within 20 seconds of the start of the exercise. If you are in a bad mood, if you are in a situation where your breath is lower than that immediately after the start of the exercise, you may want to make sure that you do not know what you are going to do. It is necessary to show that it is necessary for the parties to cooperate with each other, pay attention to them, and make sure that it is necessary to do so at the beginning of the action.
