Scientist, Robin, Newton discussed on The Science Show
Using exercised beatcancer and now has been made w a scientist of the year must be good Newton. Congratulations on being the wwl. Scientists via well. Yeah it was a great honor very important today. I'm very excited. I think it's opened up a lot of opportunities for myself and my team but also for the university I think right recognition of exercises in medicine. Yeah very very excited about it. And what do you do for the year? Well what I'm doing is promoting exercises a medicine as much as I can help trinity to get out there the message. That exercise is a medicine as effective as many pharmaceutical drugs. If not more effective in some cases and of course has nice artifacts date. Unless you do you need. But the sort of exercises that we're talking about is not simply the walking in the running but often the resistance exercise with whites and the kind of things that you do in gyms. The exercises have different sorts of effects on the body. Certainly exercise is not a single medicine. And that's an important message and you have to actually ty the medicine to address the major issue that you facing so for example if you have issues around muscle loss than walking really has no benefit. You really need resistance training fairly high volume short wrists between exercises because that creates the greatest anabolic environment. So we're looking now at really precision exercise medicine. Assessing the patient healthy individual determining what is most likely to kill them and then really honing in and targeting that with a specific exercise prescription. Well another certain people in places where I live. Who Know that the exercise the trainers know about your work. And what you've just said but how many other trainers are aware of this. Look I think probably leads the world in this field certainly American College. Sports medicine is just come out with their position. Statement on exercise and cancer management and. Look I gotta be honest. I think it's still a little bit behind where the research is. Certainly other countries around the world is very little recognition and the message is mostly just get out there and exercise out there and move. It doesn't matter what you do. Look any sort of physical activities of benefit. There's no doubt about that but we could do a lot better and certainly think it needs a lot more training of exercise physiologists and physiotherapists. I think in particular we need right understanding amongst the medical profession about benefits of exercise about how it can be tyler specifically to have much greater benefit. Well I know that when I came here just over three years ago and I went to the gym which next to way patients get chemo and there was a patient doing the exercise very very happily and I took to a number of doctors on the East Coast or maybe overseas they look blank using Compu- series. The doctors know more now. Do they look? I think that it is increasing in terms of awareness. Certainly the science is there. We have hundreds if not thousands of very high quality randomized controlled trials now which support the efficacy in the safety of targeted exercise. I think we will moving now. Though is applying exercise medicine to people who are really unwell and in the past this being hesitancy around that these people have advanced cancer. Chemotherapy and they really have overwhelming fatigue. There on well. It's too risky all the evidence that it's not if it supervised correctly in the right environment other words exercise clinic or a hospital. It is very very safe and we really need to target. That is people who aren't doing well. Those people who are perhaps even palliative. That's the time where we can really use exercise to certainly improve the quality of life that you've potentially actually extended life even if you feel really rotten you can do little bits and build on that until there's a transition realism. You get good at it absolutely and look the K. Messages some is better than none. So even if you as you say feeling really rotten try to get off the couch. You'll get out of bed and just even if it's just five ten minutes and then build on that certainly more is better than a little. We now know that if the exhaust very targeted particularly high intensity the actual volume and duration of exercise can be quite sure moderately ten or twenty minutes per day but it still can have quite a large benefit particularly saying that with resistance training body whites such as squats. This or step ups can have a very large impact on. The body's health of the body is geared. You built to move. And I've always felt that in some ways if you think of the body producing all this stuff wastes who knows. Then you've gotta get shifted and just being static doesn't make sense but is it good science as to what's going on in the body beyond my crew description the science behind this is really rapidly growing and we've moved to think beyond in cancer for example studies that show that physical activity and exercise improves quality of life. I mean that's a given. We've moved on studies to show that does improvements in strenghten cardio respiratory fitness. That's happened. We we know that well what we're trying to do. Now though understand the mechanisms by which exercise in particular actually suppresses cancer development had exercise facilitate radiation therapy for example? How does it might chemotherapy more effective? That's where we need to move now. We really looking at a molecular basis and a genetic basis here to see how certain types of exercise change the actual environment within the body systemically. We have quite vast changes chemically within the body which occur exercise a nice chemical changes have strong anti-tumor fix once understand that we'll be able to prescribe exercise more effectively because we know what chemicals drugs are released in the body by what exercise in Ham much and from there that obviously we can prescribe exercise more effectively the other aspect which is very exciting. Is that will then be able to use drugs to facilitate affect. We'll never have appeal. That replicates all the effects of exercise that star never going to happen but certainly we're learning. How exercise can work synergistically with certain chemotherapy treatments and radiation treatments to improve cancer therapy. Yeah that was the interesting thing that you're saying even way back. Then the chemo treatment for cancer was working better. If you exercise. Yes studies of patients receiving chemotherapy. We know that they have left side effects. We know that there is less dose reduction. That's very very important. Pretty much every patient will have varying degrees of toxicity chemotherapy side effects and quite often these associate via that. The doctor has to reduce the dose. That's given probably a patient will have on average about a twenty five percent dose reduction if they exercises on your at a ten percent reduction that's a considerably more chemotherapy agent that we're getting into the patient clearly that's got to translate to a better chance of actually beating the disease. You got not shirt on the West Coast Eagles. Do you actually play still now. I've never played a rugby league. We're in my younger days. Not Stein for and you get exercise yourself these days. Yes just about every day. What do all I still like to do? Resistance training two to three times per week but also got caught interested in group exercise classes in boxing classes with my wife and I go along and we hit the punching bags and the FOCUS PADS. And it's fairly high intensity it's only forty seven minutes so forty. Seven minutes is the duration of professional thought. So twelve rounds of three minutes model on that so it's a hard forty seven minutes. I think these days Robin now. I'm really going the show high-intensity work my days of doing house of exercise going. I know we shocked us. I was when I got the statistics for teenagers and around Australia. And how little money nine anything substantial? It's a major concern. This is what is driving the massive rising chronic disease and it's a challenge for the country to challenge for the health system. Because we're saying now. Teenagers who are overweight obese more than two thirds of the population and the incidence of type two diabetes increasing terrible disease. But it's a disease we don't have to have to lifestyle disease and so we really need to turn that around. In terms of that education systems their schools physical education opportunities for sport. I think in particular it is more flicking marginalized communities immigrant communities. We have to turn this around. We cannot afford where we're going. We will never be able to pay for the increasing right of chronic disease. Well congratulations again on. Keep up the good work all. Thanks Robin as always a fantastic pleasure. Swig with you.
