Know Change Know Pain

Blue marker indicates cleat postion
My last patient yesterday came in to see me with anterior knee pain. This patient recently changed to a new pair of cycling shoes and started having knee pain since 15/10/18.

Despite resting for a few days, the anterior knee pain was still there after trying to cycle on 19th and 24th October.

This patient tells me "cycling is an almost daily affair" and spends a considerable amount on the saddle.

After asking my patient a few more questions and assessing thoroughly, I was convinced the pain was triggered after changing cycling shoes.

I'm reminded of a previous post back in 2012 when Rafael Nadal changed his tennis racquet in his quest to serve better. Tennis fans would clearly remember how Roger Federer had problems affecting his back after a racquet change in 2013. In fact, after an extended period on the sidelines because of an elbow injury Novak Djokovic had to make adjustments to his tennis racquet early this year as well.

Back to my cycling patient. Before my accident when Sports Solutions was still at 108 Amoy Street, I used to cycle to work and back daily. I was very aware of the riding position on my bike. Any slightest change in saddle height, stem length or "strange noises" on the bike I would be able to notice it quickly. If you ride you bike regularly enough, you'll know I'm not exaggerating.
Superficial Front Line
After treating my patient's Superficial Front Line, it's back to cycling yesterday (after treatment) and today albeit on the trainer first and a slight change in pedaling technique.
Able to ride yesterday and today
Don't try to make key changes to your cycling, running shoes, swim technique or golf swing etc right smack in your regular season if you're competing. Just like you wouldn't use a new pair of racing shoes without trying it way before the race.

In my opinion, it's much better to use the new gear after your time off at the end of your season after you've not been riding or running etc. Your body will not be so sensitive to the changes. This I've learnt the hard way.

Just in case you're wondering, we do mark the insert inside the cycling shoe too.

Tensegrity Of The Spine

Lining up half the participants to compare their necks and backs
After Aized and Rachel did Arches and Legs last week, it's the turn of the three amigos this this two days as we do "Tensegrity of the Spine" over the next two days.
Range of movement in the spine

This course is very intense and heavy going as there's a lot of rationale behind the theory involved. Everyone (yes, you read correctly) got lost at some point today, including yours truly.

Let's hope we get a clearer picture tomorrow.

The Amazing Fiona Oakes

Picture from
I've never heard or read about Fiona Oakes before. Until my wife told me about her two days ago. She is so unassuming, humble and in her own words "I'm not really a runner". Actually she is a fantastic runner. Fiona Oakes is the fastest woman in the world to run a marathon on all seven continents and the north pole both in cumulative and elapsed time.

I thought I had it bad when I've had three knee operations before but Fiona has had seventeen knee operations and no patella (or knee cap)! Can you even imagine the rehab she has had to go through?

She was told when she was fourteen that she would find it hard to walk properly, let alone run again. It is truly amazing that she is still able to run so well. All this while being a vegan who eats one meal a day while while running an animal sanctuary.

So maybe we really don't need to eat meat and definitely not the sports and dietary supplements that are being marketed at us.

Watch the video, her partner Martin wonders how she can wake up at 3:30 am to start feeding the animals, run 20 km, come back and work all day cleaning and tending to the animals.

This just shows that the human body is truly resilient, amazing and and can perform really tremendous feats when there is a bigger cause (saving animals in Fiona's case).

If you're a runner, you have to watch the film, it's free until tomorrow.

*In case you're wondering why her running shoes look odd (I did) in the Marathon Des Sables, she's taped them up to avoid them falling apart.

Does Exercising Later In The Day Affects Your Ability To Sleep?

Zzz after a hard ride ...
I've written before in a previous post that I'm a poor sleeper. If you're like me, when I pushed myself too hard at training, I actually found it harder to fall asleep. The more I need (and want it), the harder it is for me to get it.

And sleep you know is critical for your mental and physical well being. If you're athlete, sleep is the easiest and cheapest intervention you can utilize to help your performance.

Hence, I was quite intrigued when I saw work from researchers who tested the effects of whether morning or evening workouts will affect your sleep by measuring melatonin levels. Melatonin is a hormone secreted in the pineal gland that regulates sleep and wakefulness.

Melatonin levels start to rise around your bedtime. It helps to lower your body temperature (now you know why it's so hard to fall aslleep when it's been so hot recently) and a rise in sleepiness. Melatonin levels usually peak around 3 am for most people.

The volunteers in the study were tested on three different days. A day with no exercise, a day when they exercised at 9 am or another at 4 pm. Their workout was a 30 minute  run at 75 percent VO2 max. Melatonin levels were measured with a saliva test at 8 pm, 10 pm and 3 am.

The results showed that those who did the 4 pm exercise session had much lower melatonin levels at 10 pm and 3 pm compared to the 9 am exercise group. It means that those who exercised in the afternoon (or those of you who can only train after work) will have a tougher time falling and staying asleep. End of story, period?

Not really. Don't worry if you're like most other Singaporeans who mostly have time to train only after work hours.

Melatonin is just one part of the equation in your quest to fall and stay asleep. Melatonin levels may not be the main reason why you cannot fall asleep.

For you to get a good night's sleep, it may depend on what you you eat/ drink, the wavelength of light emitted by your smart phone, the temperature of your room, your exercise routine/ intensity and not just your workout time rather than just your melatonin levels.

If you're going for a "relaxing" evening run, and clearing your head over stresses you've encountered during the day, it's gonna be a lot easier than doing sprint intervals. Although some runners may even say that the intervals make them tired and thus make them sleep better. This alone may be far more important than melatonin levels.

Another factor that is not addressed in the paper by the authors is whether genetically you are a "night owl" or a "lark"? The New York Times has a good article on how there's a strong basis on a person's natural inclination with regards to the times of day when they prefer to sleep or when they're most alert.

Some of you reading this now (after exercising late in the day and not sleeping) are likely to be "owls" and not likely to get up early to exercise since you sleep later. This may may due to your circadian wiring rather than exercise timing. So shifting your exercise timings to the morning may "rob" you of your morning sleep without helping you to fall asleep earlier.
