rate of force development (RFD) - correct answer is how fast an athlete can
develop force or simply is a measure of explosive strength
-improving an athlete's RFD may make them more explosive as they can develop larger forces in a
shorter period of time
-higher RFD's have been directly linked with better performance for jumping, sprinting, cycling,
weightlifting
stretch shortening cycle (SSC) - correct answer the 'pre stretch' or
'countermovement' action that is observed before the actual movement
-ex bending knees and dipping down before a vertical jump (strong of elastic energy within the tendon
and the muscle enables us to jump higher
-RFD is commonly believed to be manifested during the SSC
SSC-force relationship - correct answer the movement is slower with exercise
with slow-SSC because they have a longer timeframe to develop force than those with a fast-SSC
-this means slow-SSC exercises can typically create higher peak forces but lower RFD
-exercises or movements with a slow-SSC produce lower RFD's than fast- SSC movements.
fast-slow SSC movements - correct answer -exercises characterized by larger
joint displacements (work through a larger range of movement) are typically categorized as slow-SSC
movements
-exercises with smaller joint displacements are commonly referred to as fast- SSC movements
Muscle-tendon stiffness - correct answer in biomechanics "stiffness" and
"compliance" refer to the amount of deformation of an object (muscles, tendon, fascia) in relation to the
amount of force acting on the object.
-an athlete can be both super-flexible and still able to demonstrate considerable stiffness (like a high
jumper)
-stiffness contains structural and contractile components, which means that connective tissues can
adapt to become more stiff and muscles can contract faster and harder to create more stiffness
