The following video was taken by the great performance coach Rett Larson when he worked with China diving in the lead up to the 2012 London Olympics. It speaks to me of the error detection system we all have, that is so important in precision sports like diving. I honestly wouldn't be surprised if this is a deliberate dive.

It's not only important in precision sports. It's pivotal for all movement skills, from rolling over in bed to swinging a kettlebell. As coaches, our eye is trained for our clients to have a minimum acceptable movement skill, then program volume and intensity to develop capacity. The minimum acceptable standard is conceptualised as a performance bandwidth and has three reasons that govern what we consider acceptable. In the Prepare To Perform courses, we explore deeply a number of exercises used in rehab and training with the performance bandwidth in mind. Then we explore how we change this, removing the barriers to performance. 

The Victorian course (in Mornington) is sold out this weekend. The next course is Sydney September 15th and 16th, then Albury 28th and 29th. 

Best performance behaviours are high quality movements, with high force for a long time. 
Improved performance doesn’t happen until behaviour changes and it is the nervous system that permits behaviour to change.  The process of changing behaviour starts with getting the attention of the individual – whether they know it or not. Conscious and subconscious attention getting are the domains of coaching, or programming of training. Each (conscious and subconscious) has a place. 

Getting the attention of the individual requires a nervous system with healthy receptors that respond to stimuli.

The mechanoreceptors that we aim to improve attention of exist in the skin, muscles, tendons and ligaments/capsules. Enhancing the sensory environment by improving mechanoreceptor attention creates a prime environment to use the art of coaching and cueing to enhance movement skills. 

A prime opportunity exists for enhancing mechanoreceptors through the treatment of pain and improvement in mobility. Here is a digitally interactive manual that provides a video library and vast explanatory library of key mobility drills. 

For clinicians who've reduced or abolished pain, and for clinicians and coaches who've improved mobility, improving central nervous system processing is the next step - it starts with breaking patterns - a key element is auditory cueing. 
​
When you talk to an athlete to provide a cue, it requires healthy hearing. ​The role of audition and how it is used in motor performance is a largely understudied area, with some exceptions. The goal of auditory cueing is to gain attention, to break patterns, and to improve learning retention. Since auditory information is processed faster than visual information (but visual information seems to provide more useful information than auditory), it remains a pivotal tool for breaking patterns by gaining attention of the nervous system. 

Summary:

Auditory cues primarily remain useful for breaking patterns by getting attention. To be continued....
