chapter 10 Flashcards
what happens to your CM relative to your body and the ground if you ABD one arm when;
- on ground
- floating
on ground: to body = increase, to ground = increase
floating: to body = increase, to ground = same
what happens to your CM relative to your body and the ground if you ABD two arms when;
- on ground
- floating
on ground: to body = increase, to ground = increase
floating: to body = increase, to ground = same
what happens to your CM relative to your body and the ground if you ABD one leg when;
- on ground
- floating
on ground: to body = increase, to ground = increase
floating: to body= increase, to ground = same
what happens to your CM relative to your body and the ground if you ABD two legs when;
- on ground
- floating
on ground: to body = increase, to ground = decrease
floating: to body = increase, to ground = same
what happens to your CM relative to your body and the ground if you ABD both arms/legs when;
- on ground
- floating
on ground: to body = increase, to ground = decrease
floating: to body = increase, to ground = same
what happens to the distance btwn your headd and CM and the ground while floating when you ABD:
- one arm
- two arms
- one leg
- two legs
- both arms/legs
all decrease distance btwn head and CM and head and ground
factors affecting max vertical displacement
3 of them
- vertical velocity of CM at take off
- height of CM relative to ground should be max efore take off
- vertical distance of fingertips relative to CM at peak height
how do you max height of CM to ground before take off when you want to max vertical displacement
-flex arms 180 degrees
how do you max vertical distance btwn fingertips relative to CM during peak height when you want to max vertical displacement
abduct one arm as CM appraoched peak trajectory
factors affecting max horizontal displacement
3 of them
- vertical velocity at take off
- height of CM at take off
- position of segments relative to CM and bar
