Which of the following statements is incorrect regarding physical performance outcomes?

The assertion that all physical performance outcomes depend solely on overcoming gravity is incorrect because physical performance is influenced by a multitude of factors beyond just gravitational forces. While overcoming gravity is a significant component, especially in activities like running or jumping, performance outcomes also depend on factors such as technique, muscle strength, power, speed, endurance, and energy systems utilized during different activities.

For example, in sports such as swimming, athletes perform against the resistance of water rather than gravity. In cycling, performance is affected by aerodynamics and mechanical efficiency as well. Moreover, other environmental factors such as wind resistance, temperature, and altitude can also impact physical performance. Therefore, it's essential to recognize that physical performance outcomes are multifaceted and not solely determined by the need to counteract gravitational pull.
