Intro to Kinesiology
what is Kinesiology?
the scientific study of mechanics and anatomy in relation human movement
MOVEMENT IN THE ANTERIOR DIRECTION; BEING DRAWN FORWARDS is known as?
Protraction
The axis of rotation is known as the:
Pivot Point
site of attachment of the muscle on the bone that moves is known as
Insertion
every muscle in your body can act as any type of muscle mover. True or False?
True
Name 3 possible careers involved in kinesiology?
Physical Therapist, Speech Therapist, Occupational Therapist, Athletic Trainer, Exercise Physiologist, Sports Med Physician, Orthopedic Surgeon, PA, Chiropractor, Teacher, etc.
FLEXION ____________ THE ANGLE BETWEEN THE BONES and EXTENSION ____________ THE ANGLE.
Decreases, Increases
THE NUMBER OF PLANES OF MOTION A JOINT ALLOWS is known as:
Degrees of Freedom
What type of muscle can resist actions of the primary mover and works in cooperation with primary muscles by relaxing & allowing movement?
Antagonist muscles
DESCRIBES THE MOTION OF BONES RELATIVE TO THE THREE CARDINAL PLANES
Osteokinematics
The study of the human body as a machine for the performance of work has its foundations in three major areas of study: what are these 3 areas?
Biomechanics
Exercise Physiology
Neuromuscular Physiology
If the anterior bone surface is rotated towards the midline that is known as?
Internal Rotation
THE SEGMENT FURTHEST FROM THE BODY (DISTAL ASPECT) IS FREE AND NOT FIXED TO AN OBJECT is known as?
Give an example!
Open Chain Exercise
Seated leg curl, leg extension, seated chest press, bicep curls, etc.
What are the 3 types of muscular contractions? Describe what happens during these movements
Concentric contraction (shortening)
Eccentric contraction (lengthening)
Isometric contraction (static)
Is a linear stress pattern representative of an open or closed chain motion?
Closed
What are the 3 sciences associated with the subcategories of Kinesiology?
Physics, Chemistry, and Psych
Circumduction occurs in what 2 planes?
Transverse and Frontal
What are the 3 cardinal planes and identify their body divisions.
Sagittal-left/right
Transverse/Horizontal-top and bottom
What is a synergist muscle mover? Give an example.
muscle(s) that assists or helps
Hold another part of the body in position while the action in question is occurring
Support muscles usually work far away from the joint where an action is occurring.
What is the most common type of ankle sprain? Explain what happens when this type of ankle sprain occurs.
Inversion ankle sprain. When the ankle rolls inwards, stretching the connecting tissue on the lateral side within the ankle joint.
Kinesiology uses scientific based research and assessments to help with what 3 things?
1. Safety: structure movements to avoid harm to the body
2. Effectiveness: success or failure of meeting performance goals
3. Efficiency: striving to achieve movement goal with the least amount of effort.
What are the two terms applied specifically to the motions of bringing the foot upward and pushing the foot downward?
Dorsiflexion and Plantarflexion
There are 3 cardinal planes: What body motion occurs in each of the 3 planes?
Sagittal: flexion/extension
Frontal: abduction/adduction
Transverse: rotation
Someone is performing the bench press exercise. Identify the following:
-Agonist
-Synergist
-Stabilizer
Give an example for each type of joint: Uniaxial, Biaxial, and Triaxial
Elbow, Wrist, Shoulder
