A high jump approach begins with a simple J-style spin, which generates centrifugal force, propelling the athlete around the curve of the J and up over the bar. The procedure may be broken down into eight to twelve phases. In general, women run 8–10 steps while males run 10–12. However, few people complete a full rotation before jumping, so the actual number of steps taken is usually less than what might appear on the surface.
When performing a high jump, runners should start off by standing with their feet shoulder width apart and arms loose at their side. They will then swing their arms forward, pulling themselves toward the bar with each stride. As they approach it, the bar will seem to get higher and higher until they leap over it at the last minute. Once airborne, high jumpers should try to keep their bodies as upright as possible while still maintaining control; falling over backwards or face first can be extremely dangerous if not done correctly. Runners should also aim to land on both feet to avoid injury or loss of balance.
High jumpers increase speed gradually over several months of training before attempting competitions. Beginners should start off by practicing jumping as far as their height allows without running out of breath. From there, they can add distance by moving their foot landing spots farther away from each other and even on the ground if necessary. Experienced athletes can decrease their maximum reach by 5 inches (13 cm) or more through rigorous training programs.
A high jumper, while not as fast as a long jumper, must nonetheless sprint quickly to her take-off position. She transforms her forward energy to vertical momentum at the last second to jump up and over the bar. The last known high jump was performed by Russian athlete Galina Balyagina on February 17, 2003 in Moscow.
The last known long jump was achieved by American Larry Myricks on July 4, 1976 in East Meadow, New York.
Both events use the same three phases: takeoff, flight and landing. But while the high jumper needs to start from a standing position, the long jumper can take off from a crouch or even lie down. During the flight phase, which accounts for about 80% of the total length of the jump, the legs provide most of the power to the body. At the end of this phase, both athletes will have extended their arms forward in preparation for the landing phase. The long jumper uses her arms for balance and to prevent herself from falling after she jumps.
In contrast, the high jumper starts the takeoff with a quick flexion of her knees and an upward movement of her torso. This rapid sequence of movements allows her to generate enough speed to clear the bar. As soon as the high jumper has cleared the bar, she immediately begins her descent, using her arms and legs to control her velocity.
When running, launching off one foot will allow you to jump higher. Basketball players, for example, frequently hop off one foot to dunk the ball or shoot lay-ups. So, which is better: one leg or two? Two legs are better than one! Having said that, jumping with just one leg is easier and does not require as much effort as when using both feet.
The one-legged jump is useful for saving energy because you do not need to lift your body as high when jumping with one leg. This is especially important for athletes who want to maximize their performance. One study found that basketball players scored more points when they jumped with one leg rather than two.
Another advantage of jumping with one leg is that it makes it easier to balance yourself while moving forward or backward. For example, if you are playing a game of dodgeball and someone gets hit with one leg, they are less likely to be injured because they are balancing themselves better.
Finally, jumping with one leg is good for developing muscle strength in that leg. You should try to jump as high as possible whenever possible because this exercise builds up muscles that many people forget about such as the quadriceps (the large muscles on the front of your thigh) and the hamstring (the group of muscles behind your knee).
