NOTE: This page features several action props and my 'cell' props. I limit posting many materials due to ease of taking ‘screenshots’ online.

This video features the biomechanical mannequin and two other props. Scroll down this page to see a demo of the Carb Continuum Volvelle and a short description of the ‘muscle cell’ props.

Physiologics provides health professionals, gyms/yoga studios, schools, coaches, and wellness centers with innovative instructional techniques and educational materials for training staff and instructing members, students, or athletes. All lessons and programs utilize specialized visual props, graphics, videos, and schematics.

For 20-plus years, inventor and exercise physiologist Ed Watson has created educational materials and visual props for teaching principles of exercise physiology, applied nutrition, and functional medical biochemistry – with the expressed purpose to provide practical applications for both teachers and the end-user/client.

Art, metaphor, and introducing people to the origins of nutritional/exercise physiology studies meet applied biophysics – with the aim of improving peoples’ health, physical performance and recovery, nutritional knowledge, and satisfaction.

The Carbohydrate Continuum Volvelle. Volvelles are handheld ‘manual computers’ which decode and convert ‘hidden’ mathematical formulas into easily grasped visual forms – for a specific application, e.g. color wheels, star charts, etc. Rotating the volvelle translates the body’s selective depletion of fuel substrates at specific workloads into images of corresponding types of movement. In turn, the pie charts show how the relative and absolute caloric intake of macronutrients must change with intensity and activity. See the video below to see how it works.

The ‘Muscle Cell’: This image is from my book, The Physical Rules.


Consider the fact ‘hot colors’ on a weather map express ‘hot temperatures’.  You feel temperature concretely even though you do not see ‘faster molecular vibration’ of air molecules.

Thus, just as color is used  to express temperature and conceive specific intensities of air molecules ‘vibrating’, the shade of food coloring in the ‘cells’ expresses nutritional, glycolytic demand of a cell - or metabolic rate of a cell as it actively occurs at specific intensity rates within the cytosol. The candles represent mitochondria, where oxidative metabolism occurs.

I use the cell props to integrate principles of exercise physiology, nutrition, micro and macro anatomy, and more. Early lessons allow athletes and students to visualize the rate of glycogen depletion and lactate production associated with specific intensity levels, everyday activities, and physical sensations.
