In your video notes, you should have… � Defined : Base of Support, Line of Gravity, Centre of Gravity. � a note about how change in the base of support affects stability. � a note about how centre of gravity can change stability. � a note about how base of support and line of gravity link to affect stability. � Define balance and give examples of static and dynamic balance. � How can stance make a difference to stability? � Why do boxers and wrestlers compete by weight? � Do these sports also have implications for other sports? If so, which ones
Centre of Gravity (page 40) � Centre of Gravity can be defined as: ‘The point at which the weight and balance of the body is centred’ � Because the centre of mass is the point of an object where all body parts are evenly balanced, it changes depending on what position the body is in. � Stand up and raise your arms above your head. Where is your COG roughly now?
The Base of Support (page 41) � The wider the base of support and/or the greater the number of points of contact with the floor, the greater the stability � The larger the base of support the greater the stability.
Line Of Gravity or (VLG) �Line of Gravity is an imaginary vertical line that passes through the centre of gravity to the ground.
COG and Volleyball � How do the principles of balance and stability affect/improve your volleyball serve performance? � Think about different skills and write a couple of sentences for each explaining how balance is needed to perform in your 3 different volleyball skills correctly- e. g. dig, set, spike
