Motor control

Question 1

what is motor control

Answer 1

ability to regulate or direct the mechanisms essential to move

Question 2

info processing model

Answer 2

stimulus
identification
response selection
response programming
move

Question 3

donders subtractive method

Answer 3

simple RT = 1 stimulus, 1 response, RT= 200ms
go/no go RT = 2 stimulus, 1 response, RT= 230ms
choice RT =2 stimulus, 2 response, RT= 285ms

Question 4

angular momentum equation

Answer 4

moment of inertia x angular velocity

Question 5

moment of inertia

Answer 5

resistance of body to change state of angular motion (measure of distribution of mass amount an axis)

Question 6

angular momentum

Answer 6

measure of quantity of rotation of a system of matter

Question 7

why do high jumpers used curved approach

Answer 7

to produce somersault rotation

Question 8

how do long jumpers cope with forward somersault momentum

Answer 8

arms and legs circle forward to prevent rotation

Question 9

rotational energy equation

Answer 9

1/2 angular momentum x angular velocity

Question 10

how can. a twist be initiated during a somersault

Answer 10

using asymmetrical arms or hips

Question 11

how do you control unstable somersault

Answer 11

arm movement

Question 12

torque

Answer 12

force x distance
rate of change of angular momentum
