There are actually three separate qualities you need train. Power, Muscular Strength and Muscular Endurance. The next thing to consider is what types of exercise will produce similar muscular contractions through a similar range of motion. My thoughts for power would be split stance long jumps, split stance box jumps, kettlebell swings, and Olympic lifting variations if you have access to the equipment and proper coaching. For strength squats, lunges and stepups in the 6 to 8 rep range. In order to tackle the endurance aspect you could do the same squats, lunges and step ups but you would be in the 12-15 rep range.
