Quiz 3 kinesiology

Biomechanics

examines the internal and external forces acting on the human body and the effects produced by these forces

Quantitative Analysis

measurement of variables to optimize or maximize performance *recording a certain # to track performance (measurable)

Qualitative Analysis

obtaining visual or aural information to asses performance. *tracks what motion produced looks like (visual)

Acceleration

rate of change of velocity

velocity

displacement per unit of time

mass

the measure of how much matter an object has

weight

the measure of force of gravity, which is measured in newtons

balance

the base of support and location of the center of mass is manipulated

what are the types of motion?

general motion, linear motion, angular motion

what are the causes of motion?

force, constant velocity, linear motion, & angular motion

what are the three classes of levers?

1st: First Class

2nd: Second Class

3rd: Third Class

best way to maximize jump height exercise

increase the force of takeoff by strengthening the legs by doing plyometric exercises to improve explosive power

factor(s) important to athletic performance?

-balance

-technique

-strength

-speed

-flexibility

-endurance

-coordination

-agility

how can we increase stability?

-increase base of support (feet further apart)

-lower center of mass (bend knees) 

-keep center of mass within base of support (don’t lean to far)

-increase body mass/ inertia 

-increase friction with the ground (don’t slip)

how can we analyze skill?

-break it into phases

-observe

-compare

-identify errors

-correct errors (feedback)

how can we increase stability?

how can we analyze a skill?

describe the factors that affect development of movement intelligence

-starting at a young age

-learning time

-instructor

-equipment

-progression

Cognitive stage (1st stage)

when a task or skill is first introduced

Associative stage (2nd stage)

focused on preforming and refine the skill

Autonomous stage (3rd stage)

performance/ skill is automatic and very proficient

stages of motor learning

-Cognitive stage (1st)

-Associative stage (2nd)

-Autonomous stage (3rd)

Describe factors that control effectiveness of learning

-readines

-motivation

-reinforcement

-individual diferences

-learning environment

-transfer of learning

intrinsic feedback

information provided as a natural consequence of preforming an action

(ex:you feel tired after a workout) (your own body tell you)

extrinsic feedback

information provided to learner by somebody else like a coach or teacher

(ex: someone scoring you, someone correcting you, being told how you did)

knowledge of performance

feedback about the quality (HOW the skill was preformed)

ex: arm extension when hitting the tennis ball

knowledge of results

feedback about the outcome (what happened after the movement)

ex: watching the tennis ball land in the opponent’s court

progression

gradually increasing the difficulty or intensity of training/skill so the body continues to adapt and improve
