Biomechanics

Question 1

biomechanical intervensions

Answer 1

• > slight alterations to technique to optimize movement

when a coach changes your technique

Question 2

What is biomechanics of physical activity

Answer 2

applies the principles of physics and engineering to the motion, structure, and functionality of all living biological systems

Question 3

what is the point of biomechanics

Answer 3

to understand how the basic laws of physics affect and shape the structure and function of the human body

Question 4

what are the two main themes involved in studying biomechanics; briefly explain

Answer 4

Function - > how we produce forces to generate, maintain or slow down movements during physical activity
Structure - > how forces (such as gravity) affect our body tissues

Question 5

What are Newtons three laws

Answer 5

1. every object in a state of motion will stay in that state unless acted upon by an external force
2. There is a relation between an objects mass (m) its acceleration (a) and the applied force (F); F = ma
3. For every action there is an equal/opposite reaction

Question 6

explain kinematics

Answer 6

what we are able to observe visually when watching a body in motion

Question 7

types of teaching/coaching

Answer 7

quantitative (description of major joint muscles)

qualitative (measure of joint angle)

Question 8

what are kinetics

Answer 8

analysis of the actions of forces

Question 9

how can we understand movement

Answer 9

by linking kinetics and kinematics to determine forces acting on different segments of the body

Question 10

How can we asses movement

Answer 10

determining kinematics of a motion
- > naked eye, video, motion capture
determining the kinetics of a motion
- > physics equations
