The long jump primarily uses the anaerobic alactic energy system, which provides quick bursts of energy through the breakdown of stored ATP and creatine phosphate for explosive movements. Additionally, there is a contribution from the anaerobic lactic energy system as the event progresses and the athlete's muscles begin to accumulate lactic acid.

The energy system primarily used in a long jump is the anaerobic system. At the start of the jump, the athlete relies on stored ATP-PCr for immediate explosive power. As the jump progresses, the athlete transitions to anaerobic glycolysis for sustained energy production.
Kinetic energy is important for long jumpers because it helps them generate the speed and power needed to take off from the board and propel themselves through the air. By converting their running speed into kinetic energy, long jumpers can maximize their jump distance. The greater the kinetic energy they can build up, the more potential energy they have to turn into distance during the jump.
Potential energy is used to jump off a cliff, as the person's position above the ground gives them the energy to move downwards. As they jump, potential energy is converted into kinetic energy, which allows them to accelerate towards the ground.
When a girl is at the top of her jump, her mechanical energy is primarily in the form of potential energy. This is because at the maximum height of her jump, she has stored energy due to her position above the ground, which can be converted into kinetic energy as she descends back down.
The muscular system and skeletal system work together to allow the long jumper to perform. The muscles provide the force needed to jump, while the bones provide structure and support for the movement. Additionally, the nervous system plays a role in coordinating the movement and balance required for the jump.
