Clickview video – Balance & StabilityBiomechanics, VEA (2002) Select : Video Clip – Biomechanics – Balance & Stability. • Complete listening activity during the video.
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 gravitylink 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
How do we improve performance? • http://www.youtube.com/watch?v=cvOm7dPS0Uw&feature=related • What did David Wesley do wrong in his performance of the lay-up that made him miss his shot?
