This is an extended Glossary of Terms used on this website. Don't know what an eccentric contraction is? Mixed up over isometric, isotonic, and isokinetic exercises? Need to know what systole and diastole are? Can't remember which is pronation and which supination; which is the sagittal plane and which the transverse; which is the appendicular skeleton and which the axial?

It's all here, explained extensively -- especially useful for you would-be fitness trainers out there who don't want to shell out hundreds of dollars for study materials!
