누구든 35세 전후로 aging curve 가 온다

에이징 커브(Aging Curve)는 스포츠에서 선수가 늙어서 능력이 감퇴하는 것을 나타내는 표현이다. 사람의 능력에도 흥망성쇠가 있어서 나이가 들면서 성장하고 감퇴하는데, 그 정도를 분석해 함수 그래프로 수치화하면 포물선 커브 모양을 그린다고 해서 붙은 용어이다. 한국에서는 보통 노화로 인해 신체 능력이 떨어지는 현상을 노쇠화라는 용어로 부른다. 특히 스포츠 쪽에서는 선수의 나이, 경력 대비 퍼포먼스를 보고 선수의 미래 가치에 대해 이 에이징 커브를 중요한 잣대로 본다. WHAT DO WE MEAN BY "BENDING THE AGING CURVE"? THIS IS AN EXCERPT FROM BENDING THE AGING CURVE BY JOSEPH SIGNORILE. Using Exercise to Bend the Aging Curves Since we have examined some of the aging curves that affect your clients' independence, metabolic health, and fall probability, I think this is a great time to revisit the title of this book, Bending the Aging Curve. As you have seen, the majority of the curves show an exponential drop as we age as does the overall aging curve. The idea behind the title of this book, and its underlying philosophy, is that you can use targeted exercise prescriptions to improve your client's wellness and "bend" his or her aging curves. The solid line in figure 1.10 is redrawn from the neuromuscular aging curve presented in figure 1.2a. What would this line look like if you were able to improve your client's neuromuscular condition? Let's say you could produce a 30% improvement in your client at 60 years of age, a 50% improvement in your client at 75 years of age, and an 80% percent improvement in your client at 90 years of age. As you can see from the dashed line in figure 1.10, the new curve would be "bent" upward illustrating this improvement. But what about the client who has been training his or her entire life? Will that client still show an exponential drop in performance with age? The answer is yes. But as you can see from the dotted line in figure 1.10, your client that regularly exercised will have a curve that begins at a much higher level than an untrained person, and the decline often will still place the client at a level equivalent to an untrained person years younger.
