What is your engine size?

Share This Post

Have you ever wondered about the size of your own engine? You know the engine (heart, lungs and circulatory system) that drives your body?? VO2 max stands for the maximum rate that your body can consume oxygen whilst exercising. The larger the amount of oxygen that you can present and utilise at the working muscle, the fitter you are. It is like comparing a 4 cylinder engine with a V8. The latter engine has way more power and consumes way more fuel because it has a bigger capacity to deliver output. Now combine a big engine with a light body and you have the best of both worlds, case in point formula 1 race cars, which have huge engine power and a very light weight yet super strong chassis.

Now let’s put some numbers and real life examples to you. Lance Armstrong, light body, huge engine and therefore an amazing VO2 max. He has one of the biggest VO2 max scores in the world. He has been tested at around 88ml of oxygen per kilogram of body weight per minute. The average person has about one third of that ability. Obviously there is a certain amount of natural endowment with this particular element of fitness. Lance was standing near the top of the queue when this ability was being handed out. The thing that he also brought to the table was an incredible amount of determination and a tolerance level to withstand some serious discomfort.

So what about us mere mortals? It has been said that your absolute VO2 max can be improved by up to 50% with training. So you can increase the size of your engine significantly, which means you will be able to do so much more with your life where fitness is a limiting factor.

So how do you improve it? No surprises here I guess. You must adhere to some basic principles of training. First you must being doing exercises that use large muscle groups in a repetitive way for an extended period of time. Second you must progressively build how much you do because the body keeps adapting and improving.Another variable you could manipulate is the intensity. You must work at a heart rate intensity of 60-90% of your maximum heart rate, use 220-your age as a rough guide to your maximum heart rate.  Lastly, you must also consider rest and recovery because it is critical to the adaptation process.

If any of you are training for the upcoming Bridge to Brisbane you will know about training programs designed to improve your running endurance performance. You will be increasing your VO2 max and in other words your engine capacity. This will be one improvement that won’t cost you money like getting a bigger car will, on the contrary it could buy you time and improve the scope of your existence. Not a bad result for a bit of effort.

Maybe some of us have kind of dabbled in health and fitness. You know ‘The Amazing Watermelon Diet of the Stars’ in the weekly mag, or ‘Pilates is the answer to that flat belly you’ve always dreamt of’ on the prime time ‘health show’ or perhaps it was ‘Go hard or go home’ flyer of the ubiquitous 6 week challenge at the local gym that hooked you in, albeit until it got too hard or just finished.

Your Lifestyle Has Consequences

Your Lifestyle Has Consequences

Have you ever heard the saying, ‘that you become what you think about all day long’? The same also applies to exercise, ‘you become what you do or don’t do on a regular basis’. Hence the headline today. The trick with this ‘consistent exercise gig’ we all know we need is to find your motivation. If you can achieve that, you will no longer need ‘will power’, as the reason for doing it drives the action on auto pilot.
