Exam 1 Kines Intro Flashcards
what is kines?
scientific study of human movement
integrates bio mechanics, muscular anatomy, and neuromuscular physiology
we focus on musculoskeletal anatomy
what is muscular anatomy?
bones, joints, muscles, nervous system
why study kines?
means to improve performance by learning how to analyze movements of the human body and to discover their underlying principles
Three-fold purpose:
S:Safety structure movements to avoid doing harm to the body
E: Effectiveness success of failure of meeting goals of effective performance
E: Efficiency striving to achieve movement goal with least amount of effort
The two methods of study are…
qualitative: do not involve measurements or numbers, more descriptive
quantitative: data that deals with numbers and can be measured

4 step outline of kines analysis
A. Description of motor skill performance
B. Anatomical analysis
C. Mechanical analysis
D. Prescriptions for improvement
Anatomical analysis
joint actions and segment motions
muscle participation in form of contraction
neuromuscular considerations
anatomical principles related to effective and safe performance
force
muscles produce force (entities that push/pull)
magnitude (what direction force goes) (how much)
velocity
how fast something is moving
vector quantity
power
force x velocity (speed)
continuous
connects at the beginning and at the end (tumbling)
when we link things together
–running, walking, swimming etc
discrete
the isolated movements
when you can clearly find the beginning and the end of a serious of actions
–throwing, kicking, etc
simultaneous
segments move as one (overcome external forces, accuracy)
–squats
sequential
segments in an orderly sequence
when you have flow from one joint to the next but aren’t going at the same time
–throwing
