The most crucial moment of the jump is on the take-off, when the athlete's center of gravity must be raised to create vertical acceleration for a longer jump. To accomplish this, the athlete's leg muscles must cause maximal downward force. Once in flight, the most important force at work is lift. The more lift, the longer the athlete stays in the air. The more fixed and still the athlete is, the greater the lift.
Activities focus on the science of sport, the Japanese culture, and motivational activities.
