miller starts out by swimming three point eight kilometers although he much prefers the two other disciplines. to one sneeze the right take one for the team and do the swimming so we can compete together. he became a triathlete at the age of forty one he would have done it earlier if it hadn't been for the need to swim. a. few min swimming one point five or three point eight kilometers was like running to the moon as far as i was concerned. today he feels more at home in the water he then passes the baton to teo doorbell on the right or. he'll cycle one hundred eighty kilometers the perfect discipline for someone who has long experience of competing in the ironman triathlon the other say i have to do the cycling thema. not bad for an eighty year old he then passes to the youngest member of the team peter zama who is going to run the marathon and.

he too has done a number of triathlons in his time and knows what it's like. because i have great respect for you especially to you at his age i know one hundred eighty kilometers feels like it from. three men who are still happy to take on the challenge despite their age. here with dr who have done and you not only the chief physician of the protestant. church here in berlin but even of the department for jews beatrix and teaching medicine and you're an advocate of science based into the medicine. actually we focus on the physiological aging process it's off the inner organs and these aging processes are the basis for each related diseases we just saw in the report there were three

women who are doing triathlons they were all but quite fit so nobody expects to be as healthy or as fit when he. was but like when he was eighteen you know sort of so so what does healthy aging actually really we coined the term health span basically so this is the number of years that we can live without the burden of chronic disease this is what we would call health span as opposed to life span and of course we try to compress morbidity towards the end of life by all sorts of anti aging measures like prevention of knox's and prevention off risk factors and of course trying to pursue a healthy and happy life basically these factors would promote a longer health spend there are always those famous stories of an uncle or somebody

who has ninety years old always slow but never did. a lot so. it's possible that somebody who's the or. healthy get settled well i should say nature it's just not fair you know these are the examples of the lucky ones whereas others who exercise and who lead a very healthy life may have a very rare disease in younger years so you have to see the statistics and on average people who. prevent. them from smoking who focus on a healthy diet who have strong social ties these rich will be better off in later life whereas others who smoke. who have a pipe blood pressure they will happen. so this is just of course statistics so lifestyle changes are really worth. doing sports and exercise this is what we tell always in

this show get out and do some exercise but why sports helpful watch this. guy likes to keep fit he does cardio and strength training for three decades he did no sport at all but for the past three years he's exercise regularly and feels not only better but also younger. i'm told most physiological age has been reduced by several years or even a decade so i can't sit in the mirror as you did but i can definitely feel it was fun see there lots of sister. is a nurse that they hand over medical school and took part in the study there. the researchers wanted to know how the body responds when people who have been sedentary for years become more active. sixty seven volunteers were asked to exercise for half an hour a day for six months. to. do moderate insurance

training without overdoing it it has numerous anti-aging effect. on we've seen a reversal i mean aging is blood vessels and muscle function. overall but bodily functions and physical performance of the test participants were on a par with those of colleagues who were fifteen years younger. so you know. the test subjects were between forty and sixty five years of age regular exercise later improvements across the board better heart rate. lower blood pressure and blood test results that resemble those of active people up to fifteen years their junior. and the one dozen other studies in the us have looked at the central nervous system into action between nerve cells there was a great study where sixty five year olds began walking and did so regularly for a year. afterwards the connectivity in the central nervous system had improved

significantly. compared to eighteen year olds who never exercised the sixty five year olds who actually had greater connectivity in some areas of the central nervous system. and had. an active. so what actually happens in our body when we exercise. to find out researchers at the silent university medical center went a step further to examine what was happening on the cellular level. working with blood samples from athletes they separated out the white blood cells or leukocytes. these reveal very clearly how we age the white blood cells contain the key that allows you to turn back the clock of your physiological age by a number of years. it's found inside the cell nucleus in the chromosomes which contain the genetic information or d.n.a. . strand of d.n.a.

has a cap at the end known as the telomeres these caps protect the chromosome from becoming damaged. every time our cells divide the telomeres are shortened until eventually they cease to do their job causing the cells to age cease functioning or die. regular exercise appears to slow down this process. we carried out a preliminary study was so called masacre athletes and it was on the performance these are people who have done insurance training all their lives dry. marathon runners olympic champions world champions they trained on average for thirty five years and we found that in this group the aging of the selves was significantly reduced compared to people who never exercised at all that was the first indication that sport has a real anti-aging effect on. the sport rejuvenate ourselves. must effective in the aging process. the scientists had three groups to exercise

for six months. one group. the other two different forms of endurance training just went jogging normally the other did high intensity interval training . and the control group exercise it all two hundred sixty five people took part in the study. and the two groups that did insurance training the telomeres actually. the training effectively reversed the physiological age. measured the telomeres of all the test participants and found at the end durance training course the telomeres to grow by an average fifteen to twenty percent. this did not occur in the control group or amongst those doing weight training. so in durance training is a way to slow the aging process. we were surprised ourselves by the result and very pleased because it underlines the importance of india and sexercise.

that and durrance training is most effective in combating the shortening of the telomeres.
