Biomechanics Exam 1 (Week 1)Exercise biomechanics - Answer-the study of forces and their effects on human in exercise and sport
2 subdivisions of biomechanics - Answer-1. Qualitative
2. Quantitative
Qualitative Biomechanics - Answer-kinematics
Quantitative Biomechanics - Answer-kinetic
3 ways of classifying movement - Answer-1. linear or translation
2. angular or rotary
3. general (both)
Linear motion - Answer-all points of the body or object move the same distance, in the same direction
and at the same time
Angular motion - Answer-all points of the body or object move in a circle about the same axis or fixed
central line
, - ex. door hinge, movement at joint
General - Answer-- body walking
- combining the angular motions of our limbs can produce linear motions of one or more body parts
Kinematics - Answer-a branch of biomechanics describes spatial and temporal ( position, velocity,
acceleration)
Linear kinematics - Answer-deals with rectilinear (straight line) and curvilinear motions
Angular kinematics - Answer-deals with angular motions cause change in motion
Kinetics - Answer-describes forces that cause or tend to cause changes in motion (force and torque)
Linear kinetics - Answer-deals with force which can cause changes in linear motions
Angular kinetics - Answer-deals with torque or rotational force which can cause changes in angular
motions
Anatomical Planes - Answer-relate to positions in space
3 types of anatomical planes - Answer-1. Frontal
2. Transverse
3. Sagittal
Frontal plane - Answer-splits the body into front and back halves
