Analysis of Shot Put Throw Nikala Westbrook KIN 417.002 Spring 2015 References Taylor, C. (2007). These factors will then be examined throughout the three biomechanical phases; preparation, execution and follow through. The shot-putter lands on the ball of the right leg, the left foot touches down after the right foot, the feet will have a right heel to left toe relationship, so the hips can open during the putting phase. Dirty palm, clean hand – The individuals should hold the shot in the tips of their fingers – not their palm. Then the factors that determine the trajectory of the shot during flight (product factors) and the contribution of the other causal factors to the put were measured. This can be achieved by increasing the maximal height of the athlete's center of mass during this period. The throw is accompanied by the rapid extension of the right leg. In this article, he breaks down this technique into individual drills, complete with explanations and … Although there are many different factors that are important to success and performance related to the shot put … The execution stage of shot put comprises of many small critical elements. Sign up. Does shot put follow a throw-like or push-like movement pattern? The preparatory phase includes the steps taken to get the velocity needed to successfully throw the shot put, the throwing phase is what needs to happen to release the shot put, and the follow-through phase includes the steps taken to lower the arm, regain balance, and bring the thrower back to a normal standing position. Retrieved June 10, 2014, from http://www.limestone.on.ca/lesaa/FOV1-000B98E6/Training/rules%20for%20shot%20put.htm. The aim of this study is to analyse these factors in order to determine how they influence a … Place it under your jawbone, and extend your other arm in the direction of your throw. The individual rotates their torso and their back knee is bent. 24-42). • Delivery - Additional velocity is applied to the Shot by a sequenced vigorous action of the body before release. Cancer. with wind up and acceleration phases taking approximately 75% of time (1.5 seconds) It takes time to become a good thrower. The individual needs to be able to control their forward momentum after they have released the shot to ensure that they do not over step from the allowed area (Rothery, n.d). This phase includes people ages 65 and over and adults with the following health conditions that put them at high-risk for the virus:. A push-like movement pattern helps control the accuracy of shot, however, a limitation is speed (Blazevic, 2010). It is important that all shot putters and coaches keep these factors in their minds when training for shot put, biomechanics has a significant role in this sport and if this is acknowledged individuals will ultimately experience greater success. Using the arm only, push the shot out, ensuring that the elbow is kept high. Transition Phase - The movement from the rear foot landing in the centre of the circle to the other foot grounding in the front of the circle, including the initial movement of the legs upon landing. Introduction In shot-putting, the athlete tries to project the shot as far as possible while remaining within the con®nes of the throwing circle. This will enable maximum force. On Dec. 1, 2020, ACIP recommended that health care personnel and long-term care facility residents be offered COVID-19 vaccination first (Phase 1a). $lƑz�jI���J� Bronze medallist Reese Hoffa teaches the fundamentals of shot put techniques including footwork and grip. The vast majority of the time beginners will utilise a gliding technique, this is less technical and easier to understand. Shot positions . The optimum angle of release is determined largely by the height of the individual (Blazevic, 2010). How it works. Santino Logan. What biomechanical principles occur in the three different skill learning stages? All of the above takes place in an instant. Chronic kidney … The following is a blog that examines how biomecahanical factors influence shot put. However, there are many factors that must be considered when determining the optimal angle of release (Blazevic, 2010). The earliest findings of shot put date back to over 2000 years ago in the Scottish Highlands. Rotational shot put technique: Biomechanical findings and recommendations for training. Delivery Phase - The movement after the legs initiate the delivery of … For left-handed throwers, foot, leg, hand, arm and body instructions should be directed in the opposite manner. All of these activities follow a push-like movement patter where all aspect of the kinetic chain are moving together (Blazevic, 2010). When the relative release height is positive it means that the object, in the case the shot, is starting from a higher point and from the beginning has extra flight time which ultimately means that the angle of release can be less than 45° (Blazevic, 2010). Seated Position. For a beginner or untrained individual one significant influence over their ability to perform is their level of arousal (Kerr & Cox, 1991). Positioning of the shot is generally maintained behind the p As the individual extents the force moves into the arm as the shot put is released. Until this point all biomechanical components of the shot put performance have centred on the individual using the gliding technique. Xfinity. Shot Put and Discus Throwing Phases. It is important that the individuals build up speed gradually, building speed up gradually allows for greater control over the throw (Zatsiorsky et al, 1981). The Kinetic Chain. 1. Preparation/Glide/Delivery & Recovery. <>>> Swing or free leg action The initiation of the supporting leg is important while the performer lines up in the throwing direction. Optimal angle of release is determined by two factors, these being when the landing point is lower than the height of release and when the height of release is lower than the landing point (Blazevic, 2010). Basic Shot Put Technique (Shot Put Learn-By-Doing) by Mark Harsha, Portage High School Girls' Head Coach. When you’re just learning shot put, use a 4-8 pound shot to reduce the chance on injury. produce projection speed). PDF (574kB) 4411.pdf. The Shot Put can be broken down to four different phases. During the shot put glide technique, this involuntary reflex occurs when the rear leg (leg opposite to the side of the shot put) quadriceps tendon is put under excessive load (stretched) created by the increased vertical height of the athlete’s COM during the flight phase. THE COMPETITION AREA THE IMPLEMENT - The shot … The session will not result in “textbook” technique but will produce happy young learners who at least possess the minimum skills required to participate with some competence in the event. Description There are a number of purposes to this paper. Biomechanical Analysis of Shot Put Optimum Release Angle Force My angle at which I release is 38-41 degrees but is never accurate on one number due to the force of my leg and the accuracy of my elbow when it is applying force on the shot put into the neck curve Origination A wind up (see below); cocking; acceleration; deceleration; follow-through ; Biomechanics. • Glide - The thrower and Shot Put are accelerated across the circle and prepared for delivery. Drive or supporting leg action 2. Shot-Put tries were applied for our sample (the international Paralympic athlete) in eight tries, we choose the best six tries for analysis. In the shot put, the rate of stretch can be enhanced by maximizing the vertical velocity of the athlete when he lands following the flight phase. Athletics - Athletics - The shot put: The putting action is best described as shoving the shot, because the rules require that the arm may not extend behind the shoulders during the putting action. The higher the apex of the center of mass during the flight phase, the greater the athlete's vertical velocity should be upon landing. Many Asian and Non-Asian countries have their active participation in this sport. Throwing technique: Gliding or rotational. The front leg remains straight and the shot is pushed from the tips of the finger at an optimal angle. The aim is to put it as far as possible from a seven-foot diameter (2.135m) circle that has a curved 10-centimetre high toe-board at the front. KANSAS CITY, Mo. A temporal analysis of the put was made and the throwing action was divided into six phases. Olympic … London: A&C Black Publishers Ltd. Blazevic, A. J. Many of these elements have been determined before the performance, however, the individual must implement them into the performance. Dish. Available from ProQuest Dissertations & Theses Global. What is the optimum angle of release and release height? Depending on the age and gender of the athlete the weight of the implement will vary between 3km to 7.26kg. The fingers are slightly spread apart with the thumb for … The shot put is a track and field event involving "putting" (pushing rather than throwing) a heavy spherical ball—the shot—as far as possible. PHASES IN SHOT PUT COACHING POINTS. * Phase breakdown In the shot put we work on getting into the right position at each plase of the shot put throw. I developed the following sequence to teach a basic standing shot putting action to class-size groups of up to thirty children within a thirty to forty minute session. Stance. MR26202). But it really begins from the back foot, then hips, then the arms, and finally the wrist. In this article, he breaks down this technique into individual drills, complete with explanations and videos. Step 2 - ‘Glide’ The main objective of this step is to maintain and transfer momentum through the body. Fingers should be placed all close to the shot. Coach Judge does an excellent job of presenting a technical approach to training high school shot put and discus throwers. A training program has to be developed to meet the individual needs of the athlete and take into consideration many factors: gender, age, strengths, weaknesses, objectives, training facilities etc. The angle of release and height of release both play a significant role in determining how far the shot will carry, the distance is ultimately determined by the way in which force is applied (Coh, Stuhec & Supej, 2008). (2014). Rothery C. (n.d.). List of some of the major dominating Asian countries include China, Saudi Arabia, Thailand, India, Kazakhstan, Korea etc. This will also add to the balance of the individual. The shot is held at the base of the fingers, not the palm. of the shot during the first double supp ort phase, the first si ngle support phase, the flight phase, the second single support phase, and the se cond double supp ort phase. Keywords: athletics, projectile, release angle, shot put, sports biomechanics. Bend at the back knee - This is important as when this leg is extended it generates power (Blazevic, 2010). From pushing off during the acceleration part the momentum given to the shot put needs to be maintained as the athlete moves into the delivery phase. The study of biomechanics is critical for understanding the way in which the human body moves when engaging with a multitude of different activities (Watkins, 2014). Shot Put - Rotational Style - Shot should be placed on the upper pad of the hand. • Preparation - The thrower sets up correctly to commence the glide. The volume for these exercises is highest in the general and specific preparation phases while intensities are highest in the specific preparation phase and the pre-competition phase. When you’re just learning shot put, use a 4-8 pound shot to reduce the chance on injury. The way in which the individual moves is more varied when using a rotational technique, each individual will move slightly different as their body compositions are different (Bartonietz, 1994). The spherical shot is made of metal. %���� The shot is held at the base of the fingers, not the palm. �=��-0�ineϔ2�Z\H0 The throwing arm will tuck across the individuals body, this will help them to stabilise. HLPE3531 Skill Acquisition and Biomechanics for Physical Educators. London: A&C Black Publishers Ltd. Coh, M., Stuhec, S., & Supej, M. (2008). In this pattern there are many complex movements occurring all in a specific order. The significant factors in shot put include angle and height of release, speed dynamics and push-like movement. Balance is a significant factor in the follow through of shot put. Kerr, J., & Cox, T. (1991). The men’s shot weighs 7.26 kg (16 pounds) and is 110–130 mm (4.3–5.1 inches) in diameter. ; On Dec. 11, 2020, the FDA issued an Emergency Use Authorization (EUA) for use of the Pfizer-BioNTech COVID-19 vaccine external icon in persons aged 16 years and older and on Dec. 13, 2020, ACIP … Is a rotational shot put technique more beneficial than a gliding technique? A push-like movement pattern is best in shot put for many reasons, one of significance being that simultaneous motion will result in a more accurate movement due to the body travelling  in a straight-line, accuracy is extremely important in shot put to enable the shot to carry further (Blazevic, 2010). How to Do the Shot Put Glide Technique. Comparative Biomechanical Analysis of the Rotational Shot Put Technique. Shot put has been competed since the modern Olympic Games were begun in 1896. (2006) Seated Shot Put – What’s it all about? Shot putters have a choice between two techniques, the glide and the rotational (or spin) style. 2 0 obj That is now a metal not softer than brass. Fundamental Biomechanics of Sport and Exercise. 6 years ago | 234 views. The Shot Putter is required to push a steel ball as far as possible without throwing it. Speed dynamics has a significant influence over these other activities as well. Shot Put and Discus Throwing Phases. Biomechanical Analysis: Shot Put A biomechanical standpoint, the shot put and has many different aspects that can be look at upon the affects of many different factors. The individual must ensure that they have the correct stance before starting movement, they must ensure their back leg is bent at the knee and that they are applying force to the ground to enable an equal but opposite reaction as they push the shot (Blazevic, 2010). Library. The speed at which the individual is moving when performing a shot put will greatly influence the distance at which it will carry and speed dynamics play a critical role in this (Zatsiorsky, Lanka & Shalmanov, 1981). Two putting styles are in current general use by shot put competitors: the glide and the spin. stream Balance in an important factor when engaging with a shot put performance. Keywords: athletics, projectile, release angle, shot put, sports biomechanics. The shot put should lightly brush their neck. Phase breakdown In the shot put we work on getting into the right position at each plase of the shot put throw. In order to view this content, please sign in with one of our partner accounts. Coach Jim Aikens also teaches the glide technique to his athletes because it is an easier technique for them to master, and helps them develop a good finish on the ball. To analyse the shot put technique of two Olympic level female heptathletes; Introduction . On one side it is suggested that the individual should try and achieve maximum speed early on with initial movement, however, on the other side it is suggested that speed should be built up gradually (Zatsiorsky et al, 1981). By the early 1890s, the run-up had been replaced by a seven-foot-diameter circle marked on the ground with the raised board, now shaped to follow the front edge of the circle. Maximising shot put distance and velocity at the point of release through increasing momentum is of interest to coaches. How do speed dynamics influence the distance the shot will carry? Biomechanical analysis of shot putting technique. Report. Exercise and sport sciences reviews, 9, 353-389. 3 0 obj We've partnered with selected media partners in the US to bring you Olympic Channel Plus content. Then, cup the shot with your fingers and thumb along the back of … Rules for shot put. The shot, a metal ball (7.26kg/16lb for men, 4kg/8.8lb for women), is put – not thrown – with one hand. Playing next. At that time, stones were used as opposed to metal, which is what the “shot” is made out of today. Think … Rotational Shot Put Technique Explained Read More » These require that force be applied to the grou nd in order to produce momentum and velocity. The shot is then be placed under the chin with the elbow held high. Shot put phases Shot put comprises four phases: The following instructions assume the athlete is a right-handed thrower. Browse more videos. Young competitors, other than beginning shot putters , will naturally gravitate to the more direct glide technique . There is a big debate surrounding how speed should be utilised during the build up to the shot. Personality and Individual Differences, 12(10), 1075–1085. Track and field quarterly review, 93(3), 18-29. Zatsiorsky, V. M., Lanka, G. E., & Shalmanov, A. 6 years ago | 234 views. <> Grip. Arousal and individual differences in sport. 1. The shot should be placed at the base of the first three fingers, which should be evenly spread but not stretched, with the little finger and thumb supporting the shot. Shot Put comes under the track and field job event. Build speed gradually – Speed should be built up gradually rather than having a burst of speed at the beginning (Zatsiorsky et al, 1981), Simultaneous movement - The individual should move in a smooth manner with all parts of the kinetic chain moving together. Throwing the shot and disc can be a challenge. In 2014 Asian Games, While the rotational technique is an outstanding way to propel a shot put a great distance, it’s not for everyone. phase of the approach). Holding the shot put. Skip to main content.
