I see it all the time, people begin a new exercise routine and throw themselves headlong into it for a few weeks. Then, suddenly, boom, they get ill, and are forced to lay off for a week or so. This enforced lay-off unfortunately allows detraining to occur, and because the person is new to exercise, the gains disappear extremely rapidly.
Then the self-talk starts; ‘Why should I bother training, if I’ll end up ill again and lose all of my gains?’ or ‘What’s the point? Exercise is meant to make me healthier, not unhealthy.’
This negative spiral of despair continues until the person convinces themselves not to continue their exercise program any more. Chalk another person up to the Health and Fitness scrapheap.
You can’t blame them. The majority of celebrity fitness ‘experts’ and ‘gurus’, where the majority of people access their knowledge of fitness, still trot out the same old ‘no pain, no gain’, and ‘feel the burn’-esque philosophical maxims. Unfortunately just like their vacuous ‘personalities’, their knowledge of physiology and exercise is also found to be wanting.
Beyond all question, any exercise above playground clapping game level, puts your bodily systems under pressure. The body’s response to this challenge is the cause for the defensive changes and growth that is the hallmark of improved fitness.
So unless you want to limit your chosen fitness activity to lawn bowls or crazy golf which provide little challenge and therefore little gain, then you’d better learn to respect your immune system.
If you do however want to make improvements in fitness you need to use effective exercise such as resistance training or play higher intensity sports both of which overload the body quite severely. Overload is the key, but overload, taken too far leads to overtraining and system crash.
Even if you can will yourself through subsequent bouts of illness and continue training, is this really the way to go?
Take for example that a lot of elite sportspeople die earlier than the average person. How can this be? Aren’t they super fit? Yes, but years of excessive overload, whether taken to the point of clinical overtraining or not, depresses the immunity of these people and leaves them prey to disease.
The most obvious disease caused by depressed immunity is Cancer. Your body develops Cancerous cells thousands, if not millions, of times during your lifetime. In the majority of circumstances, your immune system recognises and destroys the abnormal cell before it becomes entrenched and replicates. Cancer like many other diseases are a result of immune system failure.
You may have experienced this yourself or with someone close to you. For instance, it has become popular to run marathons. Whether this be for a personal challenge or to support a charity, both of which are great causes, but a little myopic. The general training plan used by most marathon newcomers is to begin 3-6 months prior to the event and increase volume of training each week until the race date. With a lot of people they are taking a body that may not have seen exercise in maybe 10-20 years or more, and asking it to develop over a period of 12 weeks the ability to run 26 miles. Seen in that light, I’m sure you can appreciate how stressful this is to the body. And it shows, research done on both professional and recreational runners show a huge hike in infections following participation in a marathon. If you’ve attempted a marathon before, think back, did you suffer an illness during the weeks leading up or following the event, when you were supposedly at your fittest?
In fact a few years ago there was quite a high profile case that may have involved the above factors. Big Brother contestant Jade Goody in a well documented lack of preparation attempted to complete the 2006 London Marathon. Jade actually collapsed 21 miles in, demonstrating total body shut down. To complete 21 miles would have been a monumental effort for the young lady and she really should have been advised not to have participated. Two years later Jade was diagnosed with Cervical Cancer and after a valiant effort unfortunately succumbed to the disease. Were the two linked? We don’t know for sure, but to my mind the Marathon scenario sticks out like a red flag.
Your immune system is vital to prevent many diseases and your overall health, without a strong immunity you are prey to all manner of virus’s, bacteria, chemicals and other insults that your body is exposed to daily. In terms of fitness and performance, a strong immunity will take the handbrakes off, allowing you to use the full power of your motor.
In a later article I’ll show you how to bolster your immune system, here I want to leave you with a simple way to identify whether you are falling into overtraining or immune system overload.
We use four measures, three are simple assessments you can easily do at home, the last test requires the assistance of a Doctor or Medical Lab. The tests follow the acroymn HIBI.
H – Waking (H)eart Rate. This needs to be taken daily and immediately upon waking, whilst still lying in bed. If your waking heart rate is eight beats or more above the previous week’s average then this is a sign that you are overloading your immune system.
I – (I)nsomnia. If you have trouble sleeping, or maintaining a regular sleep pattern, despite feeling tired, then it’s likely you are in immunity overload.
B- (B)odyweight. This needs to be measured daily, preferably in the morning. If you find that your bodyweight has dropped by 3lbs or more below your previous week’s average then it’s a good sign you’re immune system is overloading.
I- (I)mmunity. This requires the performance of a Full Blood Count (FBC). You will either need to ask your Doctor for this test, or, if available to you, you can approach an independent lab. What you are looking for (or not looking for really) is elevated levels of Segmented Neutrophils, Lymphocytes, Monocytes and Eosinophils. If you find these measures elevated in the absence of obvious illness or injury, you are in immune system overload.
Using HIBI or just HIB to detect an overloaded immune system can help you eliminate the possibility of losing weeks and months of training gains due to illness. It may even help you reduce the possibility of developing the big diseases, which make lost training time seem trivial by comparison.
To end, I promised a follow up article to show you ways to strengthen immunity, but in the meantime, if you notice any of the above symptoms, cut back on your training to reduce the imposed stress and get more sleep. Sleep is one of the key players in immunity.
