Question

you are using the movement analysis model to analyze a swimmer in order to see what improvements can be made to help her swim faster. during one of the movement analysis steps, you remember that to move faster through the water, one must reduce the force of water resistance by making the body surfaces smooth. you then decide that, for the glide phase, you will have the swimmer keep her arms straight and close to her body to streamline her shape. which analysis step did you carry out?
determine relevant biomechanical principles and movement techniques.
observe, measure, assess, and evaluate.
consider influencing factors.
state performance goals.

Explanation:

The step of determining relevant biomechanical principles (like reducing water resistance by streamlining) and movement techniques (keeping arms straight and close) is being carried out.

Answer:

Determine relevant biomechanical principles and movement techniques.
