Consider the following graph of a sun salutation sequence, excerpted from The Science of Yoga, Pilates, & Ballet: Volume 1 from Schottenbauer Publishing:
- Which direction is initially in the vertical position: x, y, or z? Why? (Hint: What is the acceleration due to gravity at the earth's surface?)
- Separate the graph into four sections, based on position. Label each section with one of the following: (a) Bow at Waist with Hands in Front or Behind Legs, (b) Hands Up and Around to Backbend, (c) Hands Up and Around to Standing Prayer Position, (d) Standing Prayer Position.
- What are the effects of gravity on fluids in the body (blood, lymph, etc.) during these motions?
- How might these differences in acceleration affect the health benefits and/or risks of yoga?
