Document Summary
Fly : if inexperienced athletes want to move suddenly, they are unable to do so because their stance simply doesn"t allow them to get off the mark quickly. Triangle - right side up and upside down on flat surface: ex. Rotary stability: the resistance of an athlete (or object) against being tilted, tipped over, upended, or spun around in a circle, ex. airborne movements vs. landings. Types of balancing: non stable balancing. A destabilizing torque that upsets an athlete"s stability comes from gravity (improper posture control) How does carrying a long bar work for tightrope walkers? (2 points) Increased moment of inertia, therefore increased rotary resistance. The longer/heavier the pole, the easier to walk. The more bent the bar is, the lower your: stable balancing. A destabilizing torque often comes from an opponent. The axis around which athletes rotate when a torque is applied against them can be any place on their body or an opponent"s body.
