Why Study is Kinesiology?

What is Kinesiology?

Basic knowledge of biomechanics is essential in the analysis of human movement.

Summary

Using math to analyze movement

Using math to analyze movement

Select the appropriate formula to use.

Review the problem statement to determine if more information can be inferred.

Substitute the given information into the formula.

Solving Formal Quantitative Problems:

Quantitative: involving numbers

Based on collected data

Equipment necessary

Focus on forces

Examples:

Stress on shoulder during baseball pitch

Compression force on femur during landing

Qualitative: pertaining to quality (without the use of numbers)

Based on direct observation

Equipment not necessary

Focus on time and space

Examples:

Rotation of femur during golf swing

Adduction of humerus during freestyle swim

OBJECTIVES

Locomotion

Mobility impairment in elderly

Prevention of work-related injuries

Equipment design

Technique/athletic performance

Braces & shoe design

Problems studied by biomechanists:

is the branch of science concerned with the behavior of physical bodies when subjected to forces or displacements

kinetics: study of the actions of forces

kinematics: study of the appearance or description of motion

Mechanics

Dynamics: examines systems that are being accelerated.

Example: Softball pitch

Example: Sprinting

Statics: examines systems not moving or moving at a constant speed.

Equilibrium: Standing still

Example: Walking with a constant speed (no acceleration)

Mechanics

the study of human movement

What is Kinesiology?

Define mechanics, biomechanics, and kinesiology.

Define and provide examples of linear and angular motion.

Define kinematics and kinetics.

Define difference between relative & absolute reference system.

Define sagittal, frontal, and transverse planes along with corresponding frontal, sagittal, and longitudinal axes.

Explain degrees of freedom.

Describe the location of segments or landmarks using correct anatomical terms, such as medial, lateral, proximal, and distal.

Identify segments by their correct name and define all segmental movement descriptors.
