Bernie - in the previous question you answered with 'Any pose that is passive, relaxed (i.e. no muscular engagement needed), and that creates a stress in an appropriate targeted area and can be held for 2 minutes or more safely, is a Yin Yoga pose.'
Reading the Muller Schleip paper on Facial Fitness - they say 'Finally a dynamic muscular loading pattern in which the muscle is both activated and extended promises a more comprehensive stimulation of fascial tissues.' They then talk about the idea of 'soft elastic bounces in the end ranges of available motion can also be utilized for that purpose'
I wonder what your and others view is of the idea of a more 'Dynamic Yin' element. Where the 3 Tattvas are opened up to move beyond the final stillness and sometimes include a stage 4 which brings mobility to the practice?
Back to the paper again - the authors discuss the role of Dynamic Stretching in Fascial training. They talk about 'finding body movements that engage the longest possible myofascial chains (Myers 1997). This is not done by passively waiting as in a classic Hatha yoga pose... Multidirectional movements with slight changes in angle are utilized ... with this method large areas of the fascial network are simultaneously involved.'
Sorry for the long vague ramble - but trying to get my head around the question - Is Dynamic Yin a thing?
