A Podcast Network Dedicated to Effective Thinking for Potent Exercise.
 
Our current offering consists of three shows that will help bring your limitless fitness potential within reach by teaching you how to think outside the box and into the undertones of exercise.
 
Think Fit. Be Fit. is released on Mondays, Fitness for Consumption is released on Wednesdays and Peach Pit Fitness is released on the first Monday of every month. 
 
Our host roster have over 70+ years of experience in exercise science, personal training, athletic training, kinesiology and innovating throughout the fitness industry.
 
This ongoing conversation about the nuances of training will help trainers, coaches and fitness lovers connect deeper to their exercise and the process of exercise science. Let's create a new conversation about exercise!

Get ready to stretch the truth.  No, Dr. Juris and Gregory are not promoting little white lies, they’re re-investigating stretching, along with world-class neurophysiologist, Dr. David Behm. 

Stretching and flexibility are topics that seemingly can’t get settled, and there’s no shortage of conventional wisdom, from being insufficient, to being excessive.  This episode unveils the real science behind stretching and flexibility, and explains the difference between too little, too much, or being in the “Goldilocks Zone.

Listen to learn about diffuse noxious inhibitory control and how that can affect pain, relaxation and ultimately, range of motion.  Imagine how you’ll impress your friends at your next Zoom dinner party when you whip that one out!

 

Perhaps, you’re one of many who supports the objective of achieving maximum range of motion.  You may be less convinced after Dr. J reveals his research findings on highly skilled basketball players.  Dr. Behm ultimately explains the meaning of the Goldilocks Zone and Dr. J concludes with a different perspective on stretching.  The fog that surrounds stretching should finally dissipate.  Whether you stretch, or don’t, this episode is a MUST LISTEN!

 

In this episode, we discuss

  • Stretching for range of motion, warm-up and performance
  • The different stretching modalities
  • The challenges with interpreting stretching research
  • The effects of foam rolling
  • Finding the right flexibility balance
  • Considering new perspectives



Glossary

 

Acute - A condition of relatively rapid onset and short duration.

 

Autogenic inhibition - A neuromuscular process in which sensory mechanisms in tendons inhibit further contraction in the related muscles, after sensing increased tension.

 

Chronic - A condition of relatively slow onset and long duration.

 

Diffuse, noxious, inhibitory control - A process by which pain, sensed during stretching, results in inhibition and relaxation of muscles.

 

Electromechanical delay - The latency between a stretch sensed in the muscle and the ensuing contraction, or relaxation. 

 

Fascicle - A bundle of muscle fibers surrounded by connective tissue.

 

Golgi tendon organ - A specialized sensory organ, located in tendons, which responds to increases in muscle tension by inhibiting further muscle contraction.

 

Inhibition - A specific reduction in neural stimulation and activation of a muscle.

 

Muscle spindle - A sensory nerve cell, located within skeletal muscle, with specialized fibers that transmit information about change in length, and rate of change of length to the central nervous system.

 

Nuclear bag fibers - A cluster of fibers within the muscle spindle that is sensitive to dynamic changes in muscle length.

 

Nuclear chain fibers - A sequential chain of sensory fibers, located in the muscle spindle, that detects changes in the length of muscle.

 

Plastic - A semi-permanent state of muscle length.

 

Stretch tolerance - The ability of soft tissues to withstand varying degrees of stretch.

 

Thixotropic - Improving the viscosity of tissues in order to enhance fluidity and mobility.
