Triple Jump Phase

Montrail Brooks Dr. Livingston AES 364 Muscular Analysis Introduction Block starts was create out slump created to help the reasons keeper take better c be of the running surface with was made of ashes or cinder. Starting blocks has came a long way from being a single holes dug in the ground to the high tech, lightweight, but yet expensive running aid their now. To properly observe and account the breakdown of the skitter, skip, and jump patterns, while determining the muscles that cause these actions.The triple jump, referred to as the hop, skip and jump, is a running game and field event similar to the long jump. The only difference between the two is that the hop, skip, and jump contain a hop and a step, whereas the long jump involves fitting a jump. In the first phase of the triple jump, the competitor builds momentum by runing down the runway, planting their lead foot at the attach board, and hops into the air, cycling one thole around into phase two.After completin g the cycle, the lead foot strikes the ground again initiating the skip, where the opposite branching is brought up and the body goes into the bounding position. Finally as the body is glide path out of the bounding position, the opposite branch hits the ground in order to propel or jump the body forwards, aiming for distance rather than height, into the pit. pic The phases In the triple jump, there are three joints that aid in movement of the hip, the knee, and the ankle. Together the three joints let in optimum distance and proper stability for the pinny.The hip, which holds the femur and pelvis, allows the jumper to plow as his foot strikes the board. While keeping the knee in flexion, he pushes off into the cycling pattern. In the skip phase, the hip exit live in a flexed position as the trail fork goes into extension. When in the jump phase, the hip allows the pin to go from an extended position, to a partial flexed position. The knee, which hold the fibula, tibia, f emur, and patella, just like the hip is a very important part of the triple jump process.In the initial hop phase, the knee extends, but quickly switches to flexion throughout the cycling pattern. During the skip phase the knee go away remain in flexion, while extending the opposite peg offshoot. Following the second phase, the lead leg switches to the trail leg, which body in flexion for the final jump. Finally, the ankle is made up of three separate joints the talocrucal joint, subordinate tibiofibular joint, and subtalar joint. These joints, just like in the kinetic chain, are where the causality originates from.In the hop phase, the ankle of the lead leg leave alone remain dorsi flexed, and the trail leg will be slightly plantar flexed, but will quickly draw up into the dorsiflexion. As the jumper enters into the skip phase the ankle will remain dorsiflex, while the trail leg switches to the front. This will allow the trail leg to go dorsiflex, and the lead leg to deliver a powerful push-off into plantarflexion. pic The muscles and their functions in the Hop, Skip, and Jump phase.The muscles involved in the triple jump are the quads rectus fermoris (allow hip coaxal flexion and knee role extension), vastus lateralis, medialis, and intermedius (helps the knee eccentric extend) the hamstring muscles semimembranosus, semitendious, and biceps femoris (allows the jumper to extend the hip and normally pair with the help of the eccentric gluteus maximus) and finally, the lower leg muscles concentric tibialis anterior, the concentric extensor digitorum longus (which provide the ankle with the ability to perform dorsiflexion), the peroneus longus, soleus, and gastrocnemius (which allow eccentric planterflexion for that last jump push-off). The main stabilizer, the gluteus medius, acts as a front plane stabilizer and restricts the leg from turning in vargus or valgum, allowing the leg to plant. Conclusion An important factor in determining the power and mome ntum developed in the sprint start is the angle of the front leg in the set position.Most literature accepts that an angle compressed to 90 degrees is the ideal angle in this position. It allows the knee extensors to work outperform at the correct condemnation for maximum power and momentum to be developed. An angle in extravagance of 90 degrees may allow a faster leg speed out of the blocks but will not develop the kindred power and momentum. Borzov (1980) in his investigations into an optimal starting position varies a little, with a signaled ideal front leg angle of 100 degrees. Opinions on rear leg angle sidetrack between 110 degrees and cxxxv degrees. Tellez & Doolittle (1984) suggest an optimal angle of about 135 degrees for the rear leg because it allows the lever to move more quickly and allows greater impulse from a static position.They also suggest that an early body swiftness provided by the rear leg drive past the front leg is a better mechanised position to ac celerate through a more prolonged practical application of force. Conclusion An important factor in determining the power and momentum developed in the sprint start is the angle of the front leg in the set position. Most literature accepts that an angle close to 90 degrees is the ideal angle in this position. It allows the knee extensors to work best at the correct time for maximum power and momentum to be developed. An angle in excess of 90 degrees may allow a faster leg speed out of the blocks but will not develop the same power and momentum.Borzov (1980) in his investigations into an optimal starting position varies a little, with a suggested ideal front leg angle of 100 degrees. Opinions on rear leg angle vary between 110 degrees and 135 degrees. Tellez & Doolittle (1984) suggest an optimal angle of about 135 degrees for the rear leg because it allows the lever to move more quickly and allows greater impulse from a static position. They also suggest that an early body velocity provided by the rear leg drive past the front leg is a better mechanical position to accelerate through a more prolonged application of Reference Track and field News Presents Technique and Drills for the Long Jump and Triple Jump.
