Kinesiology Dictionary
Please use this dictionary of professional kinesiology terms and definitions to help you learn. New terms and definitions will be added on a regular basis for you to learn from. I have decided to extend the dictionary to include terms and definitions from sciences that relate to and support being a kinesiologist or any other healthcare professional. Knowledge itself is power - use the dictionary to empower yourself. Please use the letters in blue below as links to get to the first letter of the term you are looking for. You will be transferred to another page containing those terms and definitions accordingly. Enjoy!
