WEIGHTLIFTING
GPE - the object is lifted straight up at constant speed.
KE - The energy expended from the muscles transforms into kinetic energy as the mass is being lifted.
GYMNASTICS
GPE - The gymnast has potential energy whenever she/he is at the top of the bars due to the gymnast's weight resting there.
KE - The object at rest is the gymnast and the force applied would be swinging on a bar.
DIVING
GPE - The diver on the diving board is raised up above Earth's surface has the potential to fall because of gravity.
KE - Kinetic energy is found when the diver starts to dive from the diving board, creating a force to purposely hit the water.
