The javelin throw is a high-endurance activity that requires the entire body to move in a motion similar to throwing a spear. Lifting, carrying, and throwing the javelin at high speeds requires upper-body strength and flexibility. During the throw, abdominal or core strength and flexibility rotate the body. The legs provide propulsion when pulling the arm backward after it has been released. Throwing the javelin uses muscles from your shoulders to your hips. These include: pecs, triceps, deltoids, rotator cuffs, infraspinatus, teres major, lats, glutes, hamstrings, calves, and feet. Even though it appears as if you are only using your arms, you are actually using your whole body to propel the javelin through the air. Javelins were originally used in ancient Greece for entertainment purposes; however, they were also used in war as a form of artillery. Today, they are used as a sportive event at international competitions. There are two types of javelins: long and short. Long javelins can reach distances of up to 100 meters (328 feet), while short javelins are limited to 70 meters (230 feet). To improve your javelin throw performance, use these techniques: focus on perfecting your technique, work on increasing your speed, and practice making multiple attempts at repition.
