I am 40 years old. I am very health conscious. I have friends who are very athletic and who spend a lot of time in the mountains skiing (downhill and cross country). Some of them are 70 or even 80 years old and they are fitter then I am. I know this couple in their 80s who do 3 hours of cross country skiing a day and I could not keep up with them. They are full of energy and look about 20 years younger. I would like to find out what would be the optimum exercise level in an ideal world, if one had access to any sport and did not have to work. What kind of sports is best to develop so that one can continue to do them into a very old age? I was told that cross country skiing, swimming, walking in nature is very good as they do not place any pressure on the mechanical parts of the body, like knees or joints. What would be an ideal amount of time to exercise per day or per week?
At the moment I do Nordic walking (with sticks) in a forest for 1 – 3 hours per day. Yoga 2 hours per week. I try not to drive anywhere but walk. In the summer I mountain bike 3 times per week. In the winter I climb mountain with snow shoes and then hike in the mountains for 2 to 3 hours per day.
I know all about 30 minutes 4 times per week but I really do not think this is enough if one wants to live past 80 and be as fit and energetic as my 80 year old friends. All the very fit 70 and 80 year olds that I know do at least 1.5 hours of walking or some other exercise per day all of their lives. This is first hand information.
Are there any studies that link longevity with exercise? And also health with exercise?
