Ex Science Exam #4 Flashcards
Static Biomechanics
Examining any body mass at rest/constant motion
Dynamic Biomechanics
Examining any body mass that is speeding up or slowing down
Clinical biomechanics
Using biomechanics to understand someone in a clinical way/daily living
Sport biomechanics
Using principles to understand how to change movement for performance enhancement
Kinetics
Understanding forces that are moving an object
Kinematics
Understanding the numbers/path of movement
Types of body motion
Linear vs. Angular
What are the different planes of the body?
Frontal, Saggital( cut across sternum two sides), Transverse (cut in half top & bottom)
What is linear body motion?
All points of the body are moving in the same direction at the same speed. Rectal vs. Curvedalinear
What is angular body motion?
Where the body is moving about an “axis”
Compressive mechanical load
Things that are pressing/pushing
Tensile mechanical load
Pulling apart
Shear mechanical load
Load at perpendicular angle
Study of ergonomics:
Study of how humans interact with objects, and how they function
What is the difference between sequential vs. simultaneous link principles?
Sequential: things in a sequence (golf swing)
Simultaneous: Vertical Jump
Functional testing vs. diagnostic testing
Functional: looking at functional capactiy
Diagnostic: Looking to diagnose a clinical disease
What is validity vs. reliability
Validity: Hitting bullseye repeatedly
Reliability: Repeatability, reliably giving same answer
When testing someone’s fitness…
use their specialty
What does a metabolic cart measure?
Measure energy expenditure indirectly through oxygen consumption
What is an EKG?
Electro cardio gram
What does RER Measure?
Produced CO2/Oxygen consumed
Spirometer
Air Movement
What is an EMG
Measuring electrical activity of the muscle
EEG?
Electical activity of the brain
What is thermotherapy?
A type of therapy using heat
What is a dynamometer?
Meter that measures force
Example of measuring isometric strength:
Hand grip
What is BMI and what is it used for?
Body Mass Index, used to redflag people
DIfference between certification and licensure
Certification: set standard that requires knowledge, testing it through exam
Licensure: Specific legal documentation/standard of capabilities as a practitioner
Why is Exercise-related science having more opportunities for professional careers?
People are lazy, being sedentary increases risk of disease
DIfference between CDC and Department of Health
CDC is outbreaks/immediate health threads
HHS deals with basic human services and needs
NIH is related to research related to health risk
What are Continuing education units?
Renewing credentials to keep up to date with certifications
Single most important risk factor associated with all cause mortality?
Cardio-respiratory fitness
Modifiable risk factors
Smoking, Exercise, obesity, stress, blood glucose
Nonmodifiable risk factors
Age, genetics, race, sex,
DIfference between a clinical trial and epidemiological study
Epidemiological study: study of disease rates in correlation with another factor
Clinical research trial: experimental research with intervention
What is evidence-based medicine?
Follow what the evidence shows to implement an intervention
Healthspan vs. lifespan
Healthspan: Quality of life
Lifespan: # of years
