Question 4

Muscle fibre arrangement

Answer 4

Unipennate: when muscle fibres branch of one side of muscle.
Bipennate: when muscle fibres branch of both sides of muscle
Mulitipennate: when muscle fibres branch to all sides of muscle

Question 5

What is interplay

Answer 5

When all three energy systems work at once

Question 6

Types of contractions

Answer 6

Isotonic : when muscle contracts and muscle changes length

Isometric: when muscle applies force without changing length

Isokinetic: maximal tension is developed

Question 7

What is reciprocal inhibition

Answer 7

When muscles on one side of a bone or joint relax to allow for the other side of the bone to contract

Question 8

Systolic blood pressure

Answer 8

Pressure in the arteries when the left ventricle contracts

Linear motion

Answer 13

Is the movement of a body along a straight or curved path where all body parts move on the same direction at the same speed

Question 14

Newtons law

Answer 14

Interia
Acceleration
Action & reaction

Question 15

Interia

Answer 15

An object at rest will remain at rest unless acted upon by fierce

Question 16

Acceleration

Answer 16

A force applied to an object will produce change in motion

Question 17

Action & reaction

Answer 17

For every action their is a equal and oppose reaction

Question 18

1st class levers

Answer 18

The Axis is between the force and resistance

Eg: seashaw

Question 19

2nd class lever

Answer 19

The resistance is between the axis and force

Eg: wheelbarrow

Question 20

3rd class levers

Answer 20

The force is between the axis and resistance

Eg: biceps

Question 21

Angular momentum

Answer 21

Involves rotation around a central axis or fixed point

Question 22

Impulse

Answer 22

Force applied to an object overtime

Force X time

Question 23

Summation of forces

Answer 23

The sequence of movement of each body segment to produce maximum velocity

Question 24

Friction

Answer 24

The resistance that one surface or object encounters when moving over another

Question 25

Movements

Answer 25

Adduction: body party moves towards midline of the body Abduction: body part moves away from the midline of the body Dorsi flexion: foot moves towards shin Plantar flexion: foot moves away from shin Inversion: soul of foot rolls inwards Evervison: soul of foot rolls outwards Elevation: shoulders up depression : shoulders down

Question 26

Coefficient of restitution And factors that effect ^^

Answer 26

A measure of elasticity of bodies involves in a collision Contracting surfaces Temperature Impact Velocity

Question 27

Flexion

Answer 27

Occurs when angle decreases at the joint

Question 28

Extension

Answer 28

Occurs we angle increases at the joint

Question 31

Q=

Answer 31

Cardiac output SVxHR

Question 32

Newtons laws

Answer 32

Inertia = an object with remain at rest unless acted upon by force Acceleration= a force applied to an object will produce a change in motion Action and reaction = with every action their is an equal and oppose reaction
