BIOMECHANICS BASICS
The physics of motion exhibited or produce by biological systems
What is Biomechanics?
Examples of this measurement can be height, weight, hip and waist measurements and bone length to name a few.
What are anthropometric measurements?
This type of movement analysis describes how the body "looks" as it performs skills.
What is qualitative motion analysis?
Every force has an equal and opposite reaction force.
What is Newton's 3rd Law or Law of Action-Reaction (Reciprocal Actions)
State in which a system is at rest or is maintaining a constant velocity.
What is equilibrium?
The study of spatial and temporal characteristics of motion without regard to causative forces.
What is kinematics?
Any structure of organization of related structures whose state of motion is of analytical interest.
What is a system?
This symbol is used to represent forces in a free-body diagram.
What are arrows?
The force that resists movement between two objects in contact w/one another.
If an object is this, it is more resistant to forces intended to disrupt its equilibrium.
What is stable?
This includes motor control, motor development, and motor learning.
What is motor behavior?
This plane divides the body into top and bottom segments.
What is the transverse plane?
A scaler quantity possesses magnitude but this type of quantity adds direction to its magnitude.
What is a vector quantity?
These 2 non-contact (field) forces are important in the study of Biomechanics.
What are electromagnetic and gravitational forces?
A system with increased stability is often accompanied by decreased this.
What is mobility?
This type of skill occurs at a faster rate than feedback can be offered.
What are open-loop skills?
This most common motion is a combination of movements, such as translation and rotation.
What is general motion?
This is the qualitative approach that is sometimes described as "error analysis strategy".
What is the component approach? (to qualitative analysis)
This is the concept that explains how much the material will strain with applied forces.
What is Young's modulus?
By lowering the COG and widening the BOS, a system can increase this.
What is rotational stability?
This system is links the exercise physiology and biomechanics.
What is the neuromuscular system?
Movements can be classified an a variety of ways. These two movements describe how motion appears.
What are discrete and continuous movement?
The Pythagorean Theorem and this basic trigonometric function can help use find angles and magnitudes of vectors.
SOACOHTOA
This Principle states that the buoyant force pushing upward on a body in fluid is equal to the weight of the fluid that the body displaces.
What is Archimedes Principle?
Static, linear and rotational are all examples of this type of equilibrium.
