Correct option is D
The correct answer is (d)
Statement I suggests that to start quickly in one direction, the center of gravity should be kept low and as near as possible to the edge of the base nearest to the direction of intended motion. However, this statement is not entirely accurate.
When starting quickly in one direction, the key factor is to generate sufficient force to overcome inertia and accelerate the body forward. While keeping the center of gravity low can help improve stability and balance, placing it near the edge of the base nearest to the direction of intended motion may not always be the most effective strategy. In fact, during the initial phase of acceleration, it is often more beneficial to push off from a stable base with the center of gravity slightly behind the direction of intended motion. This allows for a more powerful push and better utilization of muscular force to propel the body forward.
Statement II focuses on stopping quickly when in rapid motion. It suggests dropping the center of gravity low, widening the base of support, and moving the center of gravity away from the edge of the base nearest the direction of movement. This statement aligns with biomechanical principles of stability and balance.
When stopping quickly from rapid motion, lowering the center of gravity helps to increase stability and reduce the risk of falling or losing balance. Widening the base of support provides a larger area for weight distribution, further enhancing stability. Moving the center of gravity away from the edge of the base nearest the direction of movement helps to counteract the momentum and decelerate effectively.
While Statement II accurately describes principles of biomechanics related to stopping quickly in rapid motion, Statement I is not entirely accurate in Its description of starting quickly.The correct answer is:
(d) Statement I is false but Statement II is true.
