Ageing well requires staying fit


Ageing is many peoples greatest fear because many believe that to age is to wane, that life doesn’t get any better but I for one haven’t seen that to be true. Working in a gym gave me an excellent insight because I saw people from all walks of life and in all stages. What I like to remind myself every so often is that the healthiest and fittest people there, and particularly the happiest were sometimes the eldest.

Now don’t get me wrong, age is a big challenge and putting the miles on the clock is going to add some wear and tear but I do like to see the body and mind just like a car. The question being, what kind of miles are you putting on and how do you drive?

In the same way that driving aggressively can cause your car to wear out sooner or by simply not maintaining it properly the body ages badly when not cared for. The fact is that working in the gym I met many people who didn’t just look younger than they were they lived younger too. I got the chance to get to know them personally and get an insight into whether their good health was luck and genetics or whether they themselves had a greater part to play.

The answer I found is that just like with a car it is luck the exact version you are given but the greatest impact on how you age is in how you take care of what you have. For example one of the ladies I knew is an inspiration to this day because I thought she was 60 and doing well for her age. To make conversation I asked her what she was training for to which she replied she was going on a skiing holiday in a few weeks. Skiing is in my eyes on of the most intense activities there is so you have to be pretty darn fit even to do it let alone be any good. This lady was treating it like a normal thing and I thought how great it is to be able to do something this intense as a normal activity at 60. Good for her, I thought, just think of all the other cool things she must be able to do that many of her age can’t like run around with her children because unfortunately even climbing stairs is a challenge for many at that age.



Because I worked in a gym I knew people ages because it’s part of prescribing the right activities and such so I had a quick check and found she was in fact 80. Yep you read that right, an 80 year old grandma thought nothing of popping across to the alps for a bit of skiing. Now that is a woman to be inspired by isn’t it. So the question is Was this exceptional health down to luck and genes. Not really because when I put the question to her she said she was always active through her life and didn’t want to let herself go. Her attitude determined her health, not her genes.

Maybe this is a lucky find but she was not the only person at this gym who had the same result. Several people I found were experiencing health 20 years younger than their nominal age. The pattern I found was that they all had the same attitude that they must use their body or lose it so they chose to maintain it well. The fact is that the body doesn’t just need a yearly check up but a more regular one a few times a week. In fact that’s what cars are like because they still need to be used regularly, often every day, in order to function properly. In fact most cars need to be given a decent run regularly enough to keep themselves working properly.

These insights didn’t just apply in the gym I worked in. When I look wider I find the same story every where. Being older can and should mean the same health and happiness you knew when you were younger. To those who maintain their body properly this is invariably the case.

So that is my personal experience so far and I wanted to see what the existing research has to say. For now though, as a working dad I have found plenty of fascinating insights but haven’t had the time to put them into an interesting story. I list them below so you can look through them.

Being more active improves your ability to prevent damage and recover

merry go round

The overwhelming feeling I get when reviewing all I’ve learned about the benefits of exercise is that the most important benefit you get is the ability to recover from any risk you take or damage or injury you incur.

Take this tweet

FFA transporters move to the plasma membrane during endurance exercise to bring more fat into the muscle. Our muscles are smart #GSSIXP

I need to find the actual source for this insight, unfortunately Kimberley didn’t cite an article because she was tweeting from a conference. That aside it’s becoming increasingly clear that all fuels that humans use for energy are dangerous when not controlled properly. Not surprising when you consider that all fuels we use outside the body like wood, oil and gas are also dangerous when not used and stored properly.

It turns out that fat, sugar and protein are all dangerous if not properly controlled. So too are other chemicals used by the body. Salt being an obvious example because one researcher, marc peletier specifically attributes salt regulation to heart disease.

So the good news is that exercise is natures way of regulating all these dangerous chemicals. The bad news is that not all the research is conclusive yet so let me give you a quick run down of what I have found.

  • Sugar: AKA Carbohydrate: Your exercise performance depends greatly on your ability to use sugar so exercise improves your ability to control and use it. Exercise targets the Glucose transporters specifically type 4 which are regulated by insulin which ensures the body can regulate sugar properly
  • Fat: Fat is of course the fuel you want to use the most of yet most people don’t know that your ability to burn fat depends on your ability to mobilise it but also your ability to use carbohyrdate. The saying goes that “You can only burn fat in a carbohydrate  flame” so of course exercise improves sugar and fat mobilisation and use. Insulin also controls fat release but the mechanism is yet to be fully understood. New evidence is coming to light but whether that includes insulin response we will find out.
  • Protein: Protein is half sugar and half amine. The amine part is toxic in large quantities so just like sugar it needs tight regulation. Exercise requires protein partly for fuel but mainly for building and repair work. What exercise does is push the body to become more able to handle the forces applied to it. Therefore it becomes less likely to break under strain. At the same time it creates a strong need to use protein and thus the systems to regulate protein become efficient and tightly regulated.
  • Salt: Salt and salts are actually crucial to the body because they have very useful chemical properties. Two very important functions are to help draw water in and out of the body as required making it easier to regulate water and keep the whole body healthy. The other is to supply the calcium and sodium required by nerves in saltatory conduction. Your entire nervous system including your brain, spine and motor circuits require specific amounts of calcium to repeatedly send message around the body
  • Water: The biggest improvement your body makes when you exercise is in water regulation. This is because every system in the body works better when water is controlled properly. Plenty of studies show that carbohydrate and fat don’t get digested or used properly if the water around them is not correct which is the basis of the sports drinks industry. Exercise puts the greatest strain possible on the bodies ability to supply, transport and regulate water and so it is no surprise that exercise forces the body to keep the required systems up to date.

As you can see from this analysis exercise puts a great and regular demand on all the body as a whole. This act itself forces the body to bring itself up to standard and reminds the body how it is supposed to work and that it must prepare for challenges. The challenge of exercise no longer exists in modern sedentary life and we haven’t yet evolved to handle this. So without the regular challenge of movement the body and its systems fall into disrepair. This is the reason that obesity, heart disease, diabetes and other diseases of western life are all being recognised as the result of the body not working as it normally would and that those who are regularly active suffer much less from these diseases if they suffer at all.

Coming from this angle you see from my list that several keys aspects of the body are kept functioning by activity. From the ability to use fuel to the ability to supply water. At the same time the improvements made to bodily systems to make this happen reduce the damage caused when these systems are not maintained.

Nutrition: A problem of supply and demand

A core concept to understand in maximising health is that our bodies are constantly managing supply and demand.

We have evolved to expect continual change and be ready for both the best and the worst which requires the ability to predict future demand. This is as true for energy as it is for other nutrients like vitamins and minerals. All nutrients are dangerous in too high a quantity and our bodies are designed to store and use them within certain limits. Thus a fine balance is what it aims for along with the ability to manage the situation if too much or too little is taken up. These cases require buffer systems to ensure no major problems occur.

The impact of this was highlighted to me when I learnt about a study that looked into the effects of both supply and demand on nutrients. In this case it was vitamin D.

The overall concept is about balance. Creating demand within the body is critical for it to make proper use of the supply. Good supply is not enough it even risks flooding your body with nutrients it’s unable to properly manage. Leading to damage and side effects.


How can Tai Chi help my daily life? Flow more, Force less

I’ve always wanted to learn about Tai Chi but never found the time. I saw a great deal from TennisOne for a course teaching Tai Chi in relation to tennis. So I thought I would take this as an opportunity to learn Tai Chi while also improving my tennis game.

Continually moving towards your goals is a principle of Cell Your Sole. To do this without overloading myself I like to combine activities and achieve more things with one period of effort. Developing my tennis game through learning Tai Chi makes Tai Chi practical right away.

Tai Chi = Unforced Balance

I’ve heard that Tai Chi is about understanding your body more so you can achieve more physically yet it’s a very relaxed approach using gentle flowing movements. This is the kind of methodology I’m looking for. I need something that:

  • fits into my daily life
  • requires minimal effort: improves me yet doesn’t demand too much.
  • prevents injury
  • improves my day to day activities: Something that is useful every day.

The course is Flow more, force less: Tai Chi Movement and Principles and is provided by Tennis One.

I like Tennis One because it takes me back in time. They aren’t up with current technology but their lessons are timeless. Tai Chi is centuries old and, I hope, as relevant today and tomorrow as yesterday.

The course is a series of lessons available through private youtube videos with downloadable versions you can keep for life if you want.

Finding Neutral

First impressions are really good. Each lesson is exactly what I want. I’ve noticed how most if not all my injuries come from me trying too hard. I push my body beyond what it is comfortable with, often for too long either in matches or practise and generally over days or weeks.
So I’m increasingly interested in the value of small purposeful movements to achieve an end instead of big powerful ones. 

Instead of training just for tennis my philosophy is to use my life to prepare me for tennis and vice versa. So I prefer to use daily tasks like walking my dog, DIY and playing with my son as opportunities to strengthen and train my body so that it is strong enough for tennis.

An easier life

Very much like in Karate Kid when painting a fence laid the foundation for the boys body to understand karate. My life is getting easier and easier as I apply this concept more. I already find that walking my dog is excellent recovery from my intense Tennis matches and sessions. At the same time the walk challenges my body and encourages strong bones, proper use of energy like fats, carbs and protein and other elements like salt a walk also encourages recovery.

Muscles around your body move rhythmically massaging blood and other items to where they need to go. Synovial fluid starts bathing your joints, nourishing them so they can heal and strengthen. The gentle pressure of the walk encourages healing in the correct direction that nature requires.

it seems fantastical to describe healing in this way but it’s how we have evolved. Gentle activity is the most natural state. Being sedentary isn’t so natural. So our bodies have evolved uses for this activity like using the contraction of the lower leg muscles to push blood back up the body into normal circulation. The motion of walking is important in moving food through the digestive system, helping the process along. As an equal and opposite reaction you find that without activity problems develop because the body is no longer getting the support it requires. Bowel problems can start because food isn’t being moved around the body. Blood may also pool in the legs because it isn’t being returned by the leg muscles through movement. This can obviously cause problems in the legs.

I’ve started the course and already I’ve found it’s just what I wanted. At first glance it’s very simple but just like in Karate Kid the more you apply and learn, the more complex you realise these basic principles are. My initial thoughts are that I have found a beautiful art I can practise every day. I’m already doing similar activities and now I have direction.

Quality over quantity

I like the delivery of Gene Burnett the instructor because it is very level and calming. He doesn’t shout or rush, everything is gentle, well explained and also made relevant to real life first. Basics like how you stand, move to look at things and how to just be. It may sound a bit fanciful but having taught in gyms and had many injuries from bad posture and technique I quickly realise how everything here is about doing a lot with a little effort. Quality over quantity.

So far I’m enjoying the course so much it feels worth writing a post for each lesson sharing what I learn.

Brain’s motor cortex uses multiple frequency bands to coordinate movement

 How and why we move is a fascinating topic. We have long known that muscle movement is coordinated through systematically triggering muscles. The trigger pattern determines the type of movement produced. New research has uncovered how this pattern is widespread throughout the brain structures involved with movement.

Synchrony is critical for the proper functioning of the brain. Synchronous firing of neurons within regions of the brain and synchrony between brain waves in different regions facilitate information processing, yet researchers know very little about these neural codes. Now, new research led by Tomoki Fukai of the RIKEN Brain Science Institute reveals how one region of the brain uses multiple brain-wave frequency bands to control movement.

Low Back Pain

I find Dr Mike Evans presentations excellent.

Back problems often come when the infrastructure of the back doesn’t work as it should. This happens for many reasons and the fix is generally to do with getting the whole system to work in a coordinated fashion again.

Mikes video is an excellent thorough intro that gives you the clear details you need. There is far too much confusing information so it’s important to start with reliable and clear details and then see what it relevant for you.

To understand how walking and related activities help you only need to put your hand on your back while you move. Feel the muscles work while you move and you see that something inherently gentle still asks enough of your back muscles and infrastructure to remind it all how to work together.

Now take a look at Katy Bowmans advice that gives you a really simply thing to do if you have low back pain.

Occasionally I suffer from back pain but I’m fortunate in that I know what causes it. Sometimes it’s induced by activity, typically tennis, and is quickly fixed with a little rest combined with improvements in technique and strengthening the affected area and improving flexibility.

Other times I have had back pain caused by too much rest. This happens when I haven’t been busy, particularly when I haven’t been as active as normal. In these cases even something as simple as walking is enough to prevent back pain for me.

Years ago I drove 1,000 miles in one week for work so I was sitting pretty much all week. That lead to back pain. I made sure I went to play football that week and it was enough to fix it.

Worse happened when I sprained my ankle. Being unable to move normally for days led to excruciating pain to the point that I couldn’t sleep or even lay down without pain. I had to sit up all night and any movement was agony. Painkillers did nothing to stop the pain. Given my previous experience I knew that moving normally would help my back. So once I could put pressure on my ankle I started moving again. This fixed most of the backpain within a day. It got my back to coordinate itself properly and stop causing pain.

As I think of it I’ve seen a few more examples of back pain, each alleviated simply by movement. It won’t fixed or help every condition though it has amazed me just how helpful it can be even in excruciating cases.

I haven’t talked about back pain yet on this blog so I hope this initial post bridges the gap well for now.

Can training your nerves improve athletic performance?

In the last post I asked Why train your nerves? It was a precursor to explaining the value of a healthy and strong nervous system to athletic performance.

In fact it is little known that the reason sedentary people improve so much when they begin exercising is because their nervous system adapts very quickly. The reason for the inevitable plateau is that the rest of the body takes much longer to adapt. So improvements then reflect the normal pace of change within the body.

Nerves adapt quickly

The specific reason for such vast improvements when people return to activity is pretty much down to nerves triggering muscles. Muscles, bones, ligaments and nerves don’t grow particularly fast so of course improvements couldn’t come from new growth. Instead muscle output and thus strength, endurance and other athletic measures depend on good coordination of all the systems involved. So the big improvements come from the coordination of muscles and at a much smaller level muscles are broken down into groups of muscle cells controlled by motor units which are groups of nerves that tell the muscle cells when to fire.

Coordinated patterns

Despite how it looks and feels it is rare for the whole of a muscle to contract (fire) at once. The reality is that each unit of muscle cells fires at a specific time aiming to produce a pattern of firing that leads to the desired result. Muscles that haven’t been used often therefore become lax at achieving and maintaining the specific firing patterns that are required. They know what to do but are out of practise. We can all relate to that. Specifically they are unable to achieve the exact pattern of firing required but they also tire sooner. They seem to run out of energy.

Lack of nerve

The evidence is that energy for the muscle to move is still there and if triggered it will move. The problem lies with the trigger system. The nerves are simply not able to trigger the muscles for long enough.

I studied sports science at university yet this explanation wasn’t part of my course. I found it delving deeper into books I found. The single point of failure was always assumed to be the muscle even though all the evidence pointed elsewhere.

So of course I’ve been waiting to take this insight further and share. That time has now come.

Muscle output: Is it neural?

An experiment we undertook during my studies at Loughborough taught me early on that it wasn’t muscle fatigue or presence of lactic acid that limited performance despite common knowledge saying otherwise.

We completed some experiments with repeated sprints and measured lactic acid and muscle output from repeated 30 second sprints on a stationary bike. Each participant was a sports science student, fitness wasn’t tested but assumed to be normal or above average.

What has always stuck in my mind was that the participants could always produce more power and muscle output in the second sprint compared to the first. This defies the logic that Lactic acid hinders performance because the second sprint always occurred with much more Lactic acid travelling through the individuals system. So, at least in this experiment Lactic Acid concentration didn’t impede exercise power output.

I was weight training from an early age so I was familiar with having more strength and power in my second set of work than my first and this experiment opened my eyes as to why. I had heard before that Lactic acid doesn’t have the impact that it’s famed for. Not in sprinting and power activities at least.

So I had always wondered if the nervous system had a greater role to play. Over time I have found articles and experiments indicating that the ability of nerves to do their job is the defining factor in performing a skill assuming someone is proficient.

This is based on these three statements:

  1. Do muscles fatigue as quickly as thought?
  2. If not Something else is the weakpoint. What is it?
  3. Does the ability of nerves to trigger muscle activity determine muscle output?

The problem is that I found much of this research before I knew about the internet. So my challenge now is to ask these questions again and see what I find.

Is the quality of energy supply crucial to the effects of Parkinsons and related heart failure.?

Following on from the finding that the ability of your brain to harness energy could explain age related mental decline? there is similar evidence that problems with energy provision could be a factor in  Parkinson’s disease and heart failure.

Researchers at Washington University School of Medicine in St. Louis investigating mouse and fruit fly hearts, found that

a protein known as mitofusin 2 (Mfn2) is the long-sought missing link in the chain of events that control mitochondrial quality.

I’m most interested in their explanation of the effects of poor mitochondrial quality

Heart muscle cells and neurons in the brain have huge numbers of mitochondria that must be tightly monitored. If bad mitochondria are allowed to build up, not only do they stop making fuel, they begin consuming it and produce molecules that damage the cell

This finding implies that the effects of Parkinson are tied to problems of energy handling. The process of getting energy from one place to another fails or is disrupted. That appears to be crucial in Parkinsons and critical to heart failure.

Put in these terms I hope it makes more sense. Throughout the body our cells rely on energy to function properly and do their part in keeping us alive and healthy. So a failure in the energy cycle which is the production, transport and use of energy will inevitably cause problems.

We see the same effects at a different scale in society. When we run out of energy whether it’s petrol for your car or electricity for your house. There are always wider effects and damage to deal with. Freezers defrosting, cars not moving, engines being damaged. Why would the body be any different.?
