Teacher Training - Muscle Spindles & GTOs

Although the Asana's (poses) of Hatha Yoga are not a system to increase flexibility (it is a system to create balance), flexibility is a consequence of asana and thus one of its main attractions. Many people look to do yoga to improve their flexibility. The theory being, the greater the range of movement at a joint, the less rigid the joint becomes. This leads to freedom of movement and increased health. When a muscle stays partially contracted (or short), an abnormal state of prolonged shortening called contracture develops. Contracture not only shortens the muscle, it makes the muscles less supple, less strong and unable to absorb the shock and stress of various types of movement. The most

How Long Should You Hold a Stretch?

The optimum length of time to hold a yoga pose is approximately 30-60 seconds if the goal of that particular pose is to increase flexibility. It is important to make clear that an increase in flexibility/range of motion is not always the reason to perform a yoga pose. In many cases the goal is simply health, movement and mobility of the muscles and joints. However, research on the hamstring muscle (Bandy, 1994) shows that 30 second stretching yields the best results. There is a theory that the stretch has to progress from the middle of the muscle across to the tendons. This process takes around 10-15 seconds of stretching. A 10 - 15 second stretch may be beneficial to the muscle in terms of

Principle of Adaption

The kinetic chain (nervous, muscular and skeletal system) seeks to maintain a state of physiological balance. Also known as homeostasis. To do this, the body must be able to adapt to the physical stresses placed on it. This ability to adapt to 'stress' is known as the general adaption syndrome. This general pattern of adaption was brought forth by Hans Seyle who showed the kinetic chain responds and then adapts to the stresses placed on it. To respond, however, the body must be confronted with a stressor that warrants a response. In yoga, the body will respond initially to a new pose with caution and then over time the body will adapt to this pose. It will then continue to adapt if the body
