A person who is motivated to exercise by competition and intensity.  

Irregular movement of a fluid with movement varying at any fixed point. Rushing or uneven flow of blood in a vessel, usually caused by a partial obstruction. A movement of gas in disorderly currents, associated with high velocity and high density with increased tubing diameter.  

Disturbed or disrupted water flow.  

Heart rate taken in the morning for three consecutive days (after waking but before rising) and then averaged.  

The imaginary horizontal plane that divides the body into upper and lower halves. A plane at right angles to the sagittal plane, running horizontally across the body.  

Readiness for change. With five stages, the model is intended to explain or predict a person’s success or failure in achieving a proposed behavior change, such as developing different habits.  

A training format that provides an option for suspended training in transitional depths (water too shallow for traditional deep-water exercise and too deep for traditional shallow-water exercise). Both suspended moves and movements touching the bottom are possible and appropriate cues must be given for safety and form.  

A verbal or nonverbal instruction to make a change in activity or direction.  

One of the three categories of transitions for deep-water exercise, this involves putting a simple movement (typically a knee-high jog) between two moves to make the transition more fluid.
