The Physiology of Yoga

surveyed had experienced a severe injury (such as concussion, dislocation, or fracture) from their sport. The findings of Wiese and colleagues (2019) were consistent with previous reports that found serious injury to be a rare occurrence in yoga (Cramer, Krucoff, and Dobos 2013; Penman et al. 2012).

One such example is the sutures between the bones of the skull, which hardly move (except during birth) in order to protect the brain.

strengthening the back extensors may provide long-term protection against vertebral fractures, independent of bone mineral density (Sinaki et al. 2002).

Another requirement is adequate mechanical loading to induce remodeling.

While a bone is a solid structure, a joint is, in a way, a nonstructure.

These signals are sent to the central nervous system, which responds by instructing the bone to build a stronger and denser framework to support the new demands.

Each individual muscle cell (also called a muscle fiber) contains long units of myofibrils, and each myofibril is a chain of tens of thousands of sarcomeres

Fibrous joints permit very little movement in order to protect the organs behind them.

the muscle contraction is isometric. The prefix iso- means same, and metric refers to length, so isometric means same length. When the muscle length changes while muscle tension remains the same, the muscle contraction is isotonic, meaning same tension.
