Posture for Engineers

Who cares about posture?

We do! (Or we should!) Those of us who work on computers daily may or may not realize the potential detriment to our health that is caused by sitting in the same position for long periods of time.

But standing desks!

Well, that is a good start, but our posture can still be affected negatively if we are standing all day (or if we do not have good standing posture).

What do we do about it?

Nerd out about posture! We can learn about the muscles that are weakened and those that are over-used during our everyday jobs, and what each of those muscles do for us when they are working properly. No need to learn all the names, but you can if you want. Anatomy is pretty cool. The most important thing is to understand what our bodies are capable of.

So what will this talk teach me?

At the end of this workshop you will: * Feel more confident about moving your body during the day. * Learn some yoga poses if you did not know them already. * Know at least a few exercises to do regularly that will help improve posture. * Know what each position will do for you. * Have tried something fun ^_^ * Be smiling!

  1. Posture for Engineers by Marylou Lenhart

  2. Konnichiwa, YAPC Asia!

  3. Our Future :C

  4. Posture! Body is adaptable, tries to be efficient Bad posture

    causes some muscles to be overworked, some to be weakened Bad posture pulls vertebrae out of alignment Seemingly unrelated symptoms can be due to spinal misalignment
  5. Chiropractic! Your spine: the center of everything If a vertebra

    in the spinal column is out of place, it puts pressure on nerves Nerves connect to every part of the body
  6. However! Chiropractic works best combined with Exercise Strengthening muscles helps

    _keep_ bones aligned correctly Otherwise you will just keep going back and never improve! As it turns out, it is not so difficult to strengthen our posture-related muscles daily
  7. Body Image Every body is different Participation is encouraged, but

    entirely _optional_ “The posture (asana) for Yoga meditation should be steady, stable, and motionless, as well as comfortable…” 
 (2.46 of the Yoga Sutra)
  8. Standing Desks? Great stuff! But we still have to use

    our muscles while standing Engaging thighs and calves, grounding through feet to strengthen arches, slight bend at knees
  9. Tadasana (Mountain)

  10. 1. Forward Head Posture Arrow from ear should line up

    with center of shoulder Weight added to sternocleidomastoid muscles: overworks them Trapezius muscles between shoulder blades are weak in this condition
  11. Exercising the Trapezius muscle Sit up against a wall or

    flat surface, shoulder blades flat against it Allowing the crown of the head to reach upward, keeping head/gaze completely level Move head forward for 4 counts, backward for 4 counts
  12. Another related muscle is the Serratus Anterior: it helps keep

    the shoulders relaxed down the back
  13. Chakravakasana (Cat/Cow)

  14. 2. “Extension” of the abdomen Weak/overstretched ab muscles Chronic lower

    back pain Tight hip flexors
  15. 3. Anterior/Posterior Pelvic Tilt “flat back” reduces natural curve in

    lumbar spine (lower back) tight abs, shortened hip extensors, weak hip flexors “weak lower back” pelvis forward and down (more than normal) weak abs, shortened hip flexors, weak gluteus maximus
  16. Exercising the Abdomen _NOT CRUNCHES_ Sit on an exercise ball!

    A couple of the following exercises…
  17. None
  18. Star Open/Close

  19. Anjaneyasana variation (Crescent Lunge)

  20. None
  21. Ardha Uttanasana (Halfway Lift)

  22. So let’s avoid this…

  23. Thank you!
