The doping crystal ball: A sporting performance future.



Not too long ago I was having a conversation with someone while we were doing some weightlifting. I was snatching that day and somehow we had come to the topic of drugs in sport. The person I was lifting with is an ironman and in the past I have worked with him to improve his nutrition and overall performance. As you may be aware performance enhancing substances are often linked with weightlifting and also since the outing of Lance (you know who I am talking about) the public is becoming aware of drugs in endurance based events. To be frank I don`t know of many sports where someone hasn`t tried something to get an advantage, golfers have had laser procedures to improve vision after all. During this conversation I told this person about the possible future of performance enhancement in sports and he seemed shocked. I told him I thought the future in performance enhancement is gene doping and about what potential things gene therapy could do. I thought it was worth sharing this information with all of you as well.

So first off what is gene doping? Gene doping is defined by the World Anti-Doping Agency as "the non-therapeutic use of cells, genes, genetic elements, or of the modulation of gene expression, having the capacity to improve athletic performance". Seems simple right? We also have to ask ourselves is it ethical and is it safe. I`ll leave these questions up to you to answer for yourself. 

So how do we detect and stop gene doping? Well I want to be clear about this the World Anti Doping Agency (WADA) and other agencies are trying to get ahead of the game here. It is well known that they had to play catch up with steroids and some other performance enhancing substances. Often I have heard through the sport grapevine that detecting for substances is done via changes in blood and urine and even now some drugs are hard to detect with current methods. Gene doping is introduced differently than these other enhancing methods.  Gene doping can be done in a number of ways these include direct injection of DNA into the muscle, insertion of genetically modified cells or utilising a virus to introduce the information. Right now you may be thinking that it sounds really far out. Gene therapy was created to help those with life threatening disease and I believe the future of medicine lies in stems cells and gene therapy. The problem exists for sporting agencies because these genes are from our genetic codes. In other words the changes that would appear seem like natural mutations in the body. For testing to be successful agencies will have to take a long term approach. Reference values may have to be established from the time an athlete starts competing. The reference values would have to take a far more comprehensive range of values and see if overall homeostasis is disturbed or altered in some shape or form.  That would include even lower levels of competition to track changes over time. This type of testing would also require tissue samples to test DNA which may have to be site specific.

It has been outlined in a basic fashion what gene doping is and how it can be administered, but how could it actually be used? Well gene doping started out in medicine to help save lives. The doping method is the same in both instances with only the outcome being different. The difference being that therapy is used for those that are very sick e.g. someone with severe anaemia requires more haemoglobin or red blood cells (RBC`s) to get oxygen around the body. In comparison a healthy athlete doesn`t require further RBC so when they dope they gain benefits which equates to an advantage i.e. getting extra capacity to carry more oxygen to muscles. There are drugs already in existence that can do something similar but they can easily be detected through testing. Another case that was brought to my attention was those born without the myostatin gene or receptors. Myostatin helps to regulate muscle growth. This happens in a number of species including humans resulting in large and powerful muscles. This is a natural mutation but since gene therapy came along for muscular dystrophy, people have turned their attention to using this for improving sporting performance.  Gene doping has even been hypothesised to be used in concert with these other changes to increase endorphins of the doping athlete to further the effects of the enhanced “abilities”.


Sounds great doesn`t it? How great would it be too be able to run all day and then lift a car and look like the Hulk. Well I want you to think about this saying  “there is no such thing as a free biological lunch” (I am not sure who said that version and if you do please tell me). Those that dope already have to weigh up the risk reward equation. Those that want to increase erythropoietin may be faced with thickening blood that may clot leading to a number of adverse outcomes. It may even come to a point that the heart may stop due to excess load. Athletes don`t seem to stop and think “what are some bigger muscle going to do to me?” There are repercussions for all doping, connective tissues such as tendons and ligaments face extra strain which may lead to sprains, strains and tearing of tendon insertions from the bone. There is also an increased metabolic cost the body having so much muscle.  These are by no means an extensive list but provide food for thought. The ultimate risk is not knowing what could happen to the rest of the body. Will those new genes affect other genes leading to a more complex adverse outcome? No one really knows the long term effects because all of this is relatively new. To me it seems crazy to even think of doing anything like this but in saying that I have always been against drugs in sport. 

So what does the future look like? Will there be hulking twelve year olds breaking weightlifting records or humans making ultra-marathons look like a walk on the beach? I can`t say. What I can say is the future is here and now. I am sure this is not the last of the discussion on gene doping and this will begin to be seen more in the public eye. Who knows maybe the future of sports will be dominated by the genetically doped and manufactured battling it out for our attention and money.  What do you think the future will look like?

Bodybuilding, Crossfit a love hate story



Crossfit V Bodybuilding who’s side are you on? Me personally it’s either both or neither depending on how you look at it. These days between the lovers and haters it seems everyone must choose a side. I want to make myself clear from the get go. I stand completely in the middle of these two methods. I live in what most people would call the grey area. As a result I often find myself in discussion with passionate lovers and haters. 

For those of you at home who haven’t yet found yourself in one of these discussions (just wait you will) there are really only two sides to this argument out there it seems. Lovers are those who see Crossfit as the be all and end all of fitness. The lovers are devotees of the WOD and mixing it up and just generally being prepared for anything. Haters are those that see Crossfit as unsafe and a fad and for whatever reason are often linked with bodybuilders.  

I would like to address both of these types of extremists because as far as I can see you both live in a different world to me. After all every fitness philosophy has perks and drawbacks and for two sides that seem to be locked in quite a headstrong battle, they share a few similarities. That’s right similarities I can hear my inbox filling up with emails already. 

Personally when I create my workouts I like to use a combination of scientific research and methods. I am also a big believer in experience being one of the greatest tools of all. Now in saying this I would like to add that I have five years of Exercise Science studying under my belt as well over ten years combined experience in Martial Arts, Olympic Weightlifting and general fitness. This combined experience fills me with confidence to draw my own conclusions over some of the methodology suggested by both Crossfit and Bodybuilding. After all why else would I pay thousands of dollars for student loans to the government if not for educated blogging? 

What specifically inspired me to write this post was a conversation held with a friend of mine. Like many people I know on both sides of the argument he is a personal trainer with decades of experience and numerous world class sporting achievements. This person in particular was a hater pure and simple. I was shocked by the remarks he was making in regards to Crossfit. Remarks such as “it`s a fad”, “it`s inefficient”, “it`s not long term”, “it`s just crap”. This seems to echo the hater community pure and simple. Other arguments are the programming has no rhyme or reason and the use of kipping is for idiots. The lovers also have a few opinions about bodybuilders. Some of the remarks include bodybuilders are not being functional and they are all about appearances. 

I would like to analyse some of these arguments. The first thing I would like to address is the common term of fad attached to Crossfit. How do you define a fad? The most common description is something that is popular for a short amount of time. Does Crossfit really fit this term? For one think Crossfit has been around for fourteen years give or take (Founded by Greg Glassman in 2000). 

Fourteen years seems like a long time for something to be a fad. So far I believe Crossfit is appearing like most things in the health in fitness industry. First every fitness philosophy starts small and then becomes more mainstream before contracting once again if not evolving into something new. This rule of expansion and contracting works for everything and does not point to Crossfit being a fad. The only things I have truly seen as fads are health and fitness gadgets sold on T.V. Honestly I can’t even tell you if Crossfit has even reached its maximum popularity yet. It could continue growing and evolving for years to come.

Another argument made against Crossfit is their high rep and high load training. Haters see it as downright dangerous pushing yourself so hard all of the time. In this instance I do agree. All research I have ever read on high rep high load Olympic lifting WODs says it will lead to technical breakdown. Technical breakdown basically means after doing the same lift over and over again it will lead to muscle fatigue which off course leads to poor technique and then potential injury. For example say you are doing high load dead lifts over and over eventually you will fatigue, your shoulders might drop and that could lead to a back injury to put it simply. These kind of WODs concern me because they have such a high risk/injury rate. Now I understand that Crossfit mantra of being prepared for anything even if it doesn’t make sense and I have nothing against it. But you can find other exercises that are physically demanding and create the same results without putting the exerciser at risk.

At first I wasn’t sure what the reasoning is behind the programming of WODs. Sometimes it seems to be done just to grind people into the ground. That was until I was attending university with a now Crossfit box owner. Instead of stacking his programming with injury inducing WODs his had a clear and intelligent design. He even ran an introductory course to WODs to ensure his clients are using proper technique. If you are willing to chat to the trainers at your local box you are likely to find other like-minded trainers writing there programs like this. 

It seems to me that Crossfit isn’t necessarily dangerous but has the same pitfalls of all competitive sports. Trainers that range from bad, good to great. I am often asked by beginners to martial arts “What’s the best style?” I reply “the teacher, master, coach is the most important thing, not the style”. I think it is no different in regards to programming be it Crossfit or any other sport or exercise endeavour. You need to find a box or gym that programs safely and makes you feel comfortable. If you are finding yourself getting injured a lot more than usual then it’s probably a sign to find a new trainer. If you are not sure what to expect then do some research of your own, the internet provides good and simple advice for free. I would like to emphasis once again this problem is found in all sports. Perhaps the only reason it seems higher in Crossfit is due to their high market saturation currently.

Now for some of the arguments surrounding Bodybuilders. I think the biggest complaint Crossfitters have against Bodybuilders is that they aren’t functional. I love this statement because every man and his dog are really behind functional training movements or exercise. It’s so strange because functional just means that it is designed to have a practical use. The problem with this is what is practical to you may not be for me. It all depends with what fitness goals you are trying to achieve or what sport you are competing in. I have had experience with writing programs for the elderly whose goals are to walk to their mailbox or climb a set of stairs. The programs I write for them are full of functional movements but as you could imagine they won’t apply to everyone equally.
So this belief that there are wrong and right functional movements really isn’t right. Just because exercises bodybuilders do don’t apply to Crossfit doesn’t make them wrong. It just makes them functional for bodybuilding. That being said a lot of these so called functional exercise are actually shared by the two sports. For example the humble squat is used by both Crossfitters and Bodybuilders alike. Yep serious a “functional” movement used by opposing groups. If you really compare the two you will find a lot more of these functional movements in common. For example, deadlifts, thrusters, chin-ups, pull ups and even lunges.

Another argument against Bodybuilding is that it’s all about appearance. Well first off let me say off course it is. During competition they are scored on appearance. Why wouldn’t you work at the very thing that gives you a higher score, after all every sport does it. For sports like Olympic Weightlifting, Martial Arts or Boxing there is a big emphasis on weight class and a lot of extra work goes into maximising you scoring potential for competition. Bodybuilders are doing the same thing by putting emphasis on their appearance. Even Crossfitters do it by utilising kipping to maximise the amount or reps they get during competition. Every athlete is looking for an edge during competitions and as far as I can see there is no reason why that is a bad thing. 

Really there is a deeper and a more complex argument going on here. Both sides seem to stereotype how the other trains even though in truth ultimately it is up to the individual not the whole. It’s hard looking past the hordes to get down to the real bare bones of any sports but until you make the effort to do so you can’t expect to understand why they do and what they do. Another key point both sides have seemed to neglect is the overarching principle of specificity. This principle is something it seems Crossfit has tried to beat but won`t as our own anatomy and physiology is the limiting factor. The idea that training with a specified set of “standards” and a few odd extra`s thrown in makes you the most fittest and prepared for anything person on the planet is limited. Bodybuilding is no different they train for appearances getting strong or fast is a side effect. Being that both are sports and yes Crossfit is now a sport it has rules like bodybuilding they are ultimately bound by the rule of specificity. If both sides laid done their ignorance and see they are just points on the continuum of movement and life they would set their differences aside and just get on with what they are doing. I would go as far to say that if there was some transfer in training both sides would benefit. Maybe it`s time they walk in each other’s shoes even if it is once a week.

Whats the best thing for weight loss.



“What`s the best thing for losing weight?”, I have heard this question so often and most likely it is the question you want to have answered. First let me backtrack I have spent a great deal of time learning about the body, working out and most things to do with health and fitness. This will culminate in a Masters in Exercise Physiology soon to be completed in the next month.  I am also a qualified P.E teacher and a training competing athlete. I have worked with people from high level athletes to the little old lady that needs to be able to lift her grocery`s.  Of all of the things that dominate the world of health and fitness, obesity is the biggest of them all (no pun intended).  

So back to the question “what is the best thing for losing weight?” this is a broad question and I’ll assume that you want to lose body fat and look and feel better.  Losing fat mass and being healthier ,because that is what we should aim for is a matter of behavior change. Right now you say so “how do I do that?” Behavior change is a complex thing but I will aim to simplify it for you. Firstly lets break it down, what is weight gain is caused by? Often weight gain is due to eating too much making poor eating choices and a lack of physical activity. So what do we do about that? Well something I am passionate about is keeping a food diary. 

First though let’s look at this more logically for example a man eats 1800 calories a day and exercises for 30minutes he burns 200 calories. He then goes and eats a chocolate bar that`s 241 calories.  It becomes a little bit clearer that what and how much we eat makes a bigger impact to our waist line then most exercise an average person may undertake. There is an old saying “you can`t train away a bad diet”. Now let me make this clear this isn`t a license to not exercise in fact diet and exercise go hand in hand. In this post though I am focusing on keeping a food diary.  A couple of extra reasons to keep a diary includes a recent study that lasted for six months published in the American Journal of Preventive Medicine found those that kept a food diary lost twice as much weight as those that didn`t. Furthermore keeping a food diary has been shown to increase the chances of losing the weight and keeping it off. A food diary can also provide insight into what you eat and what is really going into your body. So should you keep a diary in a note book? Well you can but my advice is to use technology. There are literally dozens of apps and programs for computers that are simple and effective.  These apps and programs are often free and provide easy to access food databases and information displays. Often you will find that they will be able to track food intake and exercise. The two I have had experience with is Myfitnesspal and Mapmyfitness programs. These are both accessible on multiple platforms and are free. 

Let me start with Mapmyfitness I started using this to log both my food and my exercise  and it has an easy to access menu and is easy to navigate. I found it a little bit less user friendly for the food diary portion and this was the main purpose for me to use this app. The exercise section though is great. It contains a lot of different choices and allows you to put in many selections of activity.  Something that is handy is the ability to take on fitness challenges that can often be set in your local area. How? Map my fitness has the ability for you to map a route that you take and it can tell you cool statistics like your elevation and ascent. Of course a big factor in weight loss is support and this app has the function to share your achievements with your friends and support network. 

But what about Myfitnesspal well I have been using this app for a few years now and I think it`s great. It is simple and effective. Mapmyfitness tends to be a bit overwhelming at times and for those that are used to in some degree to using a smart phone or computers this will be easy to use. The data base is quite large so more often than not you can find the food or brand you are looking for. During set up you set your weight goal and activity levels as well as the usual information. You can also choose how many meals you have and what nutritional information you see. The drawback I have found is the exercise portion is lacking a little bit. The choices of exercise are limited and though it calculates the calories burnt it can be quite off in either direction.  I tend to use a heart rate monitor to get around this and more on this in the future.  My fitness pal is redeemed by being able to input your own recipes and share your diary with other people if you wish. For me I have always advised using myfitnesspal because it is simple to use. The results for people I have worked with are always positive when they use myfitnesspal as part of their weight loss. 

A few other things though when using either program you should measure your food so you’re accurate and try to keep notes. Make using it a habit as this will take discipline but you will be rewarded much like exercising with discipline. Believe it or not keeping a diary makes you more aware and responsible and more likely to achieve you S.M.A.R.T goals. Lastly if you are thinking I don’t want to choose you can always use booth. Both programs can now be linked so you have the best of both worlds. So visit www.myfitnesspal.com and www.mapmyfitness.com now and improve your health now. Only you can achieve your own goals, no one can do it for you.
