Y&B #61 - Ground Reaction Forces in 28 Yoga Poses

10/19/17 • 37 min

What are Ground Reaction Forces (GRFs) and why are they important? In biomechanics GRF is the force exerted from the ground onto the body when they make contact. It's basically Newton's 3rd law: for every action there is a reaction. Measuring these forces helps us understand how yoga poses impact bones and possibly bone mass.

Y&B #60 - Can VR Technology Alter Pain Perception?

Can virtual reality technology affect pain perception? Well, yeah. Catherine Cowey and I discuss a fun study about this co-authored by Lorimer Moseley in 2015 in the Psychological Science Journal. The researchers used VR technology to give subjects (with a history of neck pain) the illusion that they had moved their neck more or less than they actually had. As they hypothesized, this had an effect on their perception of pain.

Y&B #62 - Buteyko Breathing and Asthma

How can Buteyko breathing help with asthma? Research shows 6-30% of asthma sufferers use breathing methods to alleviate their asthma symptoms in the UK. Catherine and I discuss a paper from the Complementary Therapies in Medicine journal about Buteyko breathing and asthma.

Buteyko breathing technique (BBT) is a method that is used in some practices to help with hyperventilation, and asthma. BBT trains people to slow their breath rate, eliminate mouth breathing (using a small strip of tape on the mouth), and use controlled breath pauses to increase CO2 levels. Russian physiologist, Konstantin Buteyko, created it in the 1950’s after experimenting with a slower breathing rate on himself and his patients. He postulated that hyperventilation and mouth breathing create hypocapnia (low CO2), which causes hundreds of ailments, including bronchospasm.
