1.1 'Standing Gamer' For Better Health (11/1/2015)
Video games are one of the biggest enablers of a sedentary lifestyle; especially if you regularly indulge in marathon gaming sessions while slumped on a couch. If you’re concerned about your overall health but don’t want to hang up your joypad, the simplest solution is to play standing. In addition to improving your posture, this can provide a swathe of side-benefits, including tempered play sessions, improved sleeping habits and sexily muscled calves.

2.2 Dynamic Sitting? (11/2/2015)
The dangers associated with sitting for too long have been widely documented, but ugh. Sitting? We spend most of our day doing that, and it can’t be that bad, right? Wrong.
Being too sedentary has been linked to an increased risk of cardiovascular disease and cancer, and spending extended periods of time hunched over your computer can affect the shape of your body by causing tissues in various areas to weaken. With that in mind, it’s no wonder dynamic—AKA active—sitting has become such a thing.
So, what exactly is dynamic sitting?
You might be picturing those bouncy-ball chairs, but that’s only part of the deal. While ergonomic chairs are helpful, dynamic sitting involves actively maintaining your body in a dynamic state versus passively sitting, and it can just as easily be achieved with a regular desk chair. “[Dynamic sitting] is designed to encourage the seated occupant to move,” explains MC Bodywork Founder Michael Ciardulli. “It’s basically sitting in motion, meaning you’re changing the posture and position of your body throughout your day.” The main goal is to avoid stiff positions, something that’s common when we get tense and stressed, as this can have extremely adverse effects on your muscles and the blood supply to your spine.

1.2 Spinal curves need to be adaptive and resilient (15/1/2015)
Spinal curves need to be adaptive and resilient. In walking,
dancing or jumping they subtly change the degree of curvature to absorb
and release force. An increase in the curve of the arch allows for
compression forces to be transferred into stretch, where they can be
stored and released to aid further movement. The spine can therefore be
likened to a spring or an upright stack of trussed arches. The following
figure exaggerates the changes in the spinal curvature for the purpose
of clarity of the action.
The
video explains the importance of maintaining Proper spinal curvatures,
and why the curvatures will need to vary dynamically to provide
springiness to movement.
My
view is that to maintain the springiness of the spinal curvatures the
way in which the feet are used and the head is balanced is also very
important. (Not to mention the attention we need to pay to footwear and
attire which are likely to impede movement and balance).
Very
few adults balance their bodies properly. Last Saturday, killing some
time in front of our rubber dealers shop, I had the opportunity to
admire the body balance of a young man, bare footed, bare chested,
wearing a traditional mundu folded up in South Indian fashion, as he
went about his work arranging 50Kg bales of rubber. Head well back,
frequently on his toes, it was poetry in motion.

2.3 Toe to Heel vs Heel to Toe running! (24/2/2015)
Dear Friends,
I
have been trying to understand the issue of good posture from an
engineering perspective since 1975 when I came across 'The Alexander
Principle' by Dr. Barlow - that's 40 years now!
As
luck would have it, I was able to get hold of a missing piece in the
jigsaw puzzle only in March 2014, pertaining to the desired movement of
the feet, which ought to be toe to heel and not heel to toe.
Combining this idea with information on how the head should be balanced, I am making remarkable progress with my posture correction.
One
immediate fallout of the idea of toe to heel movement is that I am now
able to run inside our house barefooted, making it much easier for me to
experiment with improved alignment of the legs and feet. Achieving
proper running balance, one instinctively feels, must be important to
overall postural balance. To be able to run is natural, if there is
difficulty in running something must be wrong!
In case you also wish to experiment with this idea, here are a few dos and don'ts:
1.
Correcting posture is very different from taking exercise. When taking
exercise we will set yourselves goals like we want to do 20 pushups, or
run 5 Km. The idea is 'no pain - no gain'. In posture correction since
we desire to obtain proper alignment of the musculoskeletal system we
must never push ourselves in this manner, we must stop at the first hint
of pain or excessive effort, unless we are able to reduce the pain by
adjusting the musculoskeletal system.
2.
Posture correction cannot be hurried since huge realignment of bones
and muscles must take place over the entire length of the body, so,
while walking regularly is desirable, it is better to run only when you
really feel like running. Since March 2014 I would have run inside our
house only about six times. I have marked out a distance from one corner
inside our house to another corner, a distance of 20 M - x50 makes 1
Km. That's the distance that I am running at present.
3.
Running toe to heel is tricky, it is not comparable to regular jogging,
so it will be necessary to figure the whole thing out over a period of
time. My view is that proper head balance plays an important part in
achieving proper balance.
Regards,
Selvaraj
