Basic Terminology
What is Kinesiology & Why Study it?
What is Biomechanics?
Qualitative & Quantitative Analyses
Objective for Chapter
Solve the equation for the unknown variable.

Do a “common sense” check of the answer.

Box in your answer, including the correct units of measurement.
Solving Formal Quantitative Problems:
Read the problem carefully.

List the given information.

Write down what quantity is to be solved for.

Draw a diagram of the problem situation.
Solving Formal Quantitative Problems:
Evaluate & Improve techniques in sports (PE, coach)

Provides tools to evaluate, rehabilitate and prevent injury (AT, PT, & other professions related to sports medicine)
Why Study is Kinesiology?
What is Kinesiology?
Basic knowledge of biomechanics is essential in the analysis of human movement.

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

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

Rotation of femur during golf swing
Adduction of humerus during freestyle swim
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
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)
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.
qualitative: pertaining to quality (without the use of numbers)

quantitative: involving numbers
Qualitative vs. Quantitative:
Functional Anatomy:

Body components necessary to achieve goal
Focus on function
Example: Analysis of bicep curl

Structure of the body
Focus on structure
Example: Study of biceps brachii
Anatomy vs. Functional Anatomy
Application of mechanical principles in the study of living organisms
What is Biomechanics?
