Aerobic Fitness is your best health predictor
The graph below shows the highly significant effect that cardio-respiratory fitness (CRF, or aerobic fitness) has on premature death, particularly with its effect compared to other more commonly discussed health issues. I am truly baffled that while this SHOULD be common knowledge to health and medical professionals, they rarely apply it as part of their assessment or targeted treatment!
Effect of increasing fitness
Sure, you have been advised by your health professional that you should introduce exercise in your life… that you should get out for a walk or two during the week. The graph below shows us two critical things about this advice. First is the obvious difference in protective effect of general physical activity vs fitness. You are busy, and ‘exercise time’ is hard to schedule, so the last thing we want is for you to not get the best possible return on your time investment! This data show the multiplied protective effect that increasing your fitness has on your health compared to just ‘being active’. While your low level general incidental activity is important, having a focused and safe approach to improving your fitness will reap huge returns on your investment.
Second, if you don’t know where to start, this data show that just getting underway will give you great returns. In fact, as the graph shows, even if you shift the needle from being very inactive or unfit, to being just in the lowest quarter of either ‘active’ or ‘fit people’ you achieve the greatest return on your investment! For example if you are in the lowest 10% of either ‘active’ or ‘fit’ people, you get very little protective effect; but if you move to the 25th percentile in activity levels, you get about a 10% protective effect, but a whopping 40% protective effect for being in the 25th percentile in FITNESS levels!!
Let me summarise the point I’m trying to make: While being generally active (such as going for regular easy walks, etc) is good for your health, spending time getting FITTER will give you multiplied returns, in body composition, general capacity, and primarily in health, so you can get the most out of life for as long as possible! So if you are short on time, and have high expectations on your investments, then this makes a lot of sense. NOW, if you are concerned about increasing the intensity of your exercise due to health issues, or risk of injury, please get in touch with us. We have proven systems to improve your fitness in a safe and progressive manner.
