1. All-Star Cheerleading
2. Most athletes do not demonstrate proper technique or strength, usually resulting in injury.
"Some days in tumbling, we do not even do the skill they are working on. For instance, a back handspring requires strength in plyometrics, core, shoulders, hamstrings, and glutes, and the athlete also must know how to engage her head, core, and power bases. I have seen many people spend thousands of dollars on a back handspring when all they needed to do was strengthen their body appropriately and the skill would have been easy.
Athletes must follow progressions from A to Z to learn well and completely. Plus, it will keep them injury-free and psychologically relaxed. Conditioning is extremely important, so do not neglect it."

3. My Hypothesis:
If a spring floor is used, a cheerleader falling from 10 ft would not break their bones, contrary to on other surfaces.
4. I plan on testing the critical heights of surfaces used by cheerleaders in order to find the potential of bone breakage that would occur at or above those critical heights. I plan to use the vernier force plate to measure the force exerted by the collision of a weight and the surface I'm testing. I will take into account the height at which the weight is dropped, the velocity of the object before it hits the surface, the work done on the object, and the impulse, deformity or energy lost in the resulting impact. The tools I will use will be a meter stick for height, scale for weight, equations to find work done and impulse.By finding this data I can compare it to data found in different studies that give numbers for the force required to break bone and critical heights of certain surfaces.
