Professor Ed Watson, Consulting Exercise Physiologist




A seasoned lecturer at Saint Paul College, exercise physiologist and personal trainer for over 21 years, Mr. Watson is a true showman who creates specialized props while he provides science based - visually oriented education and training curriculum – for teaching students of any age, athletes and coaches,  professional staff or members of yoga studios and gyms actually all audiences.

Yes… most props can be utilized for all audiences! The trick is tweaking specific content and concepts while using specific customized materials. All this provides practical applications for your needs, reference guides and lessons for teachers, and education and training for end-users.

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.










VolvelleThe 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.


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.
