"Travis' data shows that his arms work as relatively fixed levers to transfer the force he generates with his body.   The stand out information is the considerable amount of tricep activity he produced.  According to the data, he is engaging the long head of the triceps which acts at the shoulder joint, specifically extension.  The action of applying force to the paddle through the "pulling arm" as it moves from  the catch towards the body explains this activity."

Fixed Levers. Good way of putting it.

"He also engages his pecs and lats considerably.  Pec major activity was slightly higher overall than lat activation at each intensity relative to the respective MVC's.   This makes sense - the pecs are an interesting muscle group.  Simply put, anything that the lats do, the pecs do and more. At sprint speed the pecs were just above MVC whereas the lats were just below.  Pec activation occurs at the shoulder joint in the transfer of trunk force through both the upper and lower arms."

Is the upper arm pushing forward via pec muscle while the lower arm is acting like a lever? Or is the entire upper body just locked in a triangle while the core/hip provide power?
