PSYCHOPHYSIOLOGY, MIND-BODY INTEGRATION, AND HEALTH BEHAVIOR
Maya has a taken a summer job working on a cruise ship. "Sunshine, vacation, here I come," she thinks. She will be teaching water aerobics, beginning yoga, and a morning "rise and shine" walking class. Maya anticipates that this will be a nice change from the four part-time jobs she has been working for the past several years.

Thankfully, her kinesiology coursework, her years of experience, and her continuing education classes have kept her up to date in the health field, so she can answer the deluge of questions she receives, refer clients appropriately, and make informed decisions about the situations she encounters.
Her first surprise client presents himself in her beginning yoga class on the afternoon of departure. Nick is several years older than the others in the class and stiff as a board, but, with the attitude of a man ready to conquer the world, he muscles his way through the postures, pushing himself to the point of straining, and ignoring Maya's instructions to the class to go slowly and gently.

Maya's first priority is to keep everyone free of injury. How is she going to connect with Nick and help him work with his body rather than against it?
Understanding and applying the psychology of health and fitness requires basic knowledge of psychophysiology and health. ...
