Are you imagining proper form?

Just imagine proper form and you can increase strength in your pinky finger 35%.

Imagine Increased Muscle Strength!-Experiment

In a fascinating experiment, researchers at the Cleveland Clinic Foundation discovered that a muscle can be strengthened just by thinking about exercising it.
For 12 weeks (five minutes a day, five days per week) a team of 30 healthy young adults imagined either using the muscle of their little finger or of their elbow flexor. Dr. Vinoth Ranganathan and his team asked the participants to think as strongly as they could about moving the muscle being tested, to make the imaginary movement as real as they could.

Compared to a control group – that did no imaginary exercises and showed no strength gains – the little-finger group increased their pinky muscle strength by 35%. The other group increased elbow strength by 13.4%.

What's more, brain scans taken after the study showed greater and more focused activity in the prefrontal cortex than before. The researchers said strength gains were due to improvements in the brain's ability to signal muscle. ( Society for Neuroscience, Annual Meeting, November 11, 2001 )


This might explain why form over function is so important in weight lifting.  Form is about getting the correct muscles to fire at the best time in the function of moving the weight from A to B via a path that is most likely not a straight line. Making sure your are firing the right muscles is the job of the brain - the mind controls the brain and it is the mind that imagines, predicts, and sees the future desired state.

Does this relate to other types of activities?  Could we receive a 35% increase in effectiveness just by disciplined practice of proper form in a thought experiment, rather than an actual experience.   I think we could see benefit in this way.

David's notes on "Drive"

- "The Surprising Truth about what Motivates Us" by Dan Pink.

Amazon book order
What I notice first and really like is the subtle implication in the shadow of the "i" in Drive is a person taking one step in a running motion.  This brings to mind the old saying - "there is no I in TEAM".  There is however a ME in TEAM, and there is an I in DRIVE.  And when one talks about motivating a team or an individual - it all starts with - what's in it for me.

Introduction

Pink starts with an early experiment with monkeys on problem solving.  Seems the monkeys were much better problem solver's than the scientist thought they should be.  This 1949 experiment is explained as the early understanding of motivation.  At the time there were two main drivers of motivation:  biological & external influences.  Harry F. Harlow defines the third drive in a novel theory:  "The performance of the task provided intrinsic reward" (p 3).  This is Dan Pink's M…

Exercise:: Definition of Ready & Done

Assuming you are on a Scrum/Agile software development team, then one of the first 'working agreements' you have created with your team is a 'Definition of Done' - right?



Oh - you don't have a definition of what aspects a user story that is done will exhibit. Well then, you need to create a list of attributes of a done story. One way to do this would be to Google 'definition of done' ... here let me do that for you: http://tinyurl.com/3br9o6n. Then you could just use someone else's definition - there DONE!

But that would be cheating -- right? It is not the artifact - the list of done criteria, that is important for your team - it is the act of doing it for themselves, it is that shared understanding of having a debate over some of the gray areas that create a true working agreement. If some of the team believes that a story being done means that there can be no bugs found in the code - but some believe that there can be some minor issues - well, …

Refactoring - examples from the book

Martin Fowler's book Refactoring:  Improving the Design of Existing Code has a simple example of a movie rental domain model, which he refactors from a less than ideal object-oriented design to a more robust OO design. Included in this Refactoring_FirstExample.zip Zip file are the Java source code files of the Movie, Rental, and Customer classes. Along with a JUnit CustomerTest class. Using these example source files you too can follow along with the refactoring that Fowler presents in the first few chapters of his book.


Team Performance Model - by Drexler and Sibbet

Many of you have all heard of the Tuckman model of team dynamics (Forming, Storming, Norming, Performing).  It was created in 1966 and has become the most popular model for describing team behavior.  Is it time to level up in your mental model of team dynamics?  Are you ready for a richer more functional model?

Orientation - Why am I here?
"Orientation is about understanding the purpose of a team and assessing what it will mean to be a member.  you need to understand the reason the team exist, what will be expected of you and how you will benefit from membership.  In a new team, these are individual concerns, because the group is only potentially a team.  that is why these concerns are illustrated as occurring in your imagination at an intuitive level.  As a team leader it is important to provide time and space for people to answer these internal questions themselves."

Do You Put “CSM” After Your Name?

I’ve noticed a new trend—people have been gaining titles. When I was younger, only doctors had initials (like MD) after their names. I always figured that was because society held doctors, and sometime priests (OFM) in such high regard that we wanted to point out their higher learning. I hope it was to encourage others to apply themselves in school and become doctors also. Could it have been boastful?

The Wikipedia describes these “post-nominal initials”:
Post-nominal letters, also called post-nominal initials, are letters placed after the name of a person to indicate that the individual holds a position, educational degree, accreditation, office, or honor. An individual may use several different sets of post-nominal letters. The order in which these are listed after a name is based on the order of precedence and category of the order. That’s good enough for me.
So I ask you: is the use of CSM or CSP an appropriate use of post-nominal initials?
If your not an agilista, you may wonder …
