Define functional strength - ✔✔The ability of the NM system to contract eccentrically, isometrically and
concentrically in all three planes of motion
Define neuromuscular efficiency - ✔✔The ability of the human movement system to allow agonists,
antagonists, synergists and stabilizers to works synergistically to produce, reduce and dynamically
stabilize the entire human movement system
Define integrated training - ✔✔A comprehensive approach that attempts to improve all components
necessary for an athlete to perform at the highest level and prevent injury
Define the stretch-shortening cycle - ✔✔An active stretch (eccentric contraction) of a muscle followed
by an immediate shortening (concentric contraction) of that same muscle
In a stretch-shortening cycle, what are needed to decrease the time between the concentric and
eccentric contraction? - ✔✔Stabilization strength
Core strength
Neuromuscular efficiency
What is the mechanism behind balance training? - ✔✔Stimulates neuromuscular adaptations leading to
improved intramuscular and intermuscular coordination, that is, recruiting the right muscles to work at
the right time with the right amount of force for the desired outcome.
Define rate coding and what does it mostly pertain to? - ✔✔Muscular force can be amplified by
increasing the rate of incoming pulses from the motor neuron after all prospective motor units have
been activated
What is the main function of plyometric training? Mechanism behind it? - ✔✔Rate of force production
regulated by the CNS, how quickly a muscle can generate force (Force x velocity)
,Overloads the stretch-shortening cycle to enhance neuromuscular efficiency, rate of force production
and reduce neuromuscular inhibition by stimulating the proprioceptive mechanisms and elastic
properties of the HMS.
Why is stabilization training important before strength and power training? - ✔✔research has shown
that inefficient stabilization can lead to...
1) Altered force production in muscles
2) Increased stress at joints
3) Tissue overload
4) Injury (Cumulative injury cycle)
What are the requirements for embarking on power training? - ✔✔Reserved for athletes who have
demonstrated...
1) Postural control
2) Balance
3) Core strength and stability
4) Excellent landing mechanics
What are the two main subdisciplines of Biomechanics and what are they defined as? - ✔✔1)
Kinesiology: The study of human movement
2) Biomechanics: A physics term involving the study of how forces affect a living body
Equal-opposite reaction forces that are felt when walking on the ground are also known as...? -
✔✔Ground reaction forces
What is quantitative and qualitative analysis and how do they differ and what are they apart of? -
✔✔Both are apart of analyzing human motion, a.k.a. biomechanical analysis
,Quantitative: involves taking physical measurements and making mathematical computation to reach a
conclusion
Qualitative: involves applying principles of proper technique and combining them with observations in
order to make an educated evaluation.
In an eccentric muscle contraction, the overall tension within the muscle is ____ than the external forces
trying to lengthen the muscle - ✔✔Less
What are the four behavioral properties of muscles? - ✔✔Extensibility: Ability of being stretched or
lengthened
Elasticity: muscle's ability to return to normal or resting length after it has been stretched
Irritability: muscle is able to respond to stimulus
Ability to develop tension
What soft tissue components make up the deep longitudinal subsystem? - ✔✔Erector spinae
Thoracolumbar fascia
Sacrotuberous ligament
Biceps femoris
Peroneus longus
What is the function of the deep longitudinal subsystem?*
*Extra credit - ✔✔Stabilization of the lumbosacral joint complex and medial longitudinal arch of foot
eccentric deceleration of forward leg swing
, control of pronation and supination of the foot ankle/complex from heel strike through mid-stance
Potentially the primary mechanism of propulsion during lower intensity walking
Proprioceptive mechanism communicating information about ground reaction forces during high
intensity activity
What components belong to the Anterior Oblique Subsystem? - ✔✔Internal/external oblique muscles
Adductor complex
Hip external rotators
What is the function of the Anterior Oblique Subsystem? - ✔✔Aid in pelvic stability and rotation
contributing to leg swing
Factor in the stabilization of the SIJ
What are the components of the lateral system? - ✔✔Gluteus medius
Tensor fascia latae
Adductor complex
QL
What is the function of the lateral system? - ✔✔Frontal plane stability
