Preparation/Glide/Delivery & Recovery. In this case, we have to concentrate upon two aspects very carefully and they are − 1. The individuals must also ensure that they do not leave the circle until their shot has landed (Rothery, n.d). The difference between the two comes down the ability to have movement, with an open kinetic chain movement is enabled at one end of the chain and with a closed kinetic chain movement is not enabled at either end (Blazevic, 2010). How it works. Please select below. Shot Put and Discus Throwing Phases. As the individual extents the force moves into the arm as the shot put is released. Holding the Shot. This will enable maximum force. Many of these elements have been determined before the performance, however, the individual must implement them into the performance. 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. THE COMPETITION AREA THE IMPLEMENT - The shot … We've partnered with selected media partners in the US to bring you Olympic Channel Plus content. The statement that a trained athlete has a better understanding of how to build speed is not surprising, these individuals are trained to react to these situation in a specific way. 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. In this article, he breaks down this technique into individual drills, complete with explanations and videos. The left arm is dragging behind to delay the rotation of the Dish. 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). All of these activities follow a push-like movement patter where all aspect of the kinetic chain are moving together (Blazevic, 2010). The fingers are slightly spread apart with the thumb for support. (2006) Seated Shot Put – What’s it all about? Balance in an important factor when engaging with a shot put performance. How does this influence the distance that the shot will carry? 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). This was invented in the United States in 1876. Library. There is a considerable disadvantage that comes with using a push like movement and this is that the individual is not able to produce a shot at a greater speed due to the muscle movement within the body (Blazevic, 2010).

Although you need strength to throw a shot put, technique and form are much more important than muscle definition. Most world-class male throwers, including 2009 World champion Christian Cantwell, employ the rotational shot put technique. Watch fullscreen. Direct TV. Playing next. In the case of shot put, the landing point is lower than that of the release height, this means that the relative release height is positive. The higher the apex of the center of mass during the flight phase, the greater the athlete's vertical velocity should be upon landing. The aim of this study is to analyse these factors in order to determine how they influence a shot put performance . Shot Put and Discus Throwing Phases. The phases are the Shot grip and placement, delivery of the shot… In Sports Biomechanics: The Basics (2nd ed., pp. Keywords: athletics, projectile, release angle, shot put, sports biomechanics. Description There are a number of purposes to this paper. Are throwers will either throw starting in the power position or the glide position. Think … Rotational Shot Put Technique … 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. Shot put, at first though, seems to be a relatively easy task, however, when broken down there are numerous small biomechanical factors that determine whether the performance will be successful or a failure. In order to view this content, please sign in with one of our partner accounts. Shot Put - Rotational Style - Shot should be placed on the upper pad of the hand. 1 0 obj When you’re just learning shot put, use a 4-8 pound shot to reduce the chance on injury. endobj When you shoot the shot, flick your wrist in a way similar to how you would shoot a basketball or netball. 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. Holding the shot put. While the rotational technique is an outstanding way to propel a shot put a great distance, it’s not for everyone. Available from ProQuest Dissertations & … ATHLETICS OMNIBUS - SHOT PUT From the Athletics Omnibus of Richard Stander, South Africa 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. Throwing technique: Gliding or rotational. Positioning of the shot is generally maintained behind the p endobj In order to do this drill, the athlete must apply force. In this pattern there are many complex movements occurring all in a specific order. stream Rules for shot put. Drive or supporting leg action 2. The optimum angle of release for an individual is the ratio between the horizontal and vertical velocity (Coh et al, 2008). (304788526). Shot Putt Training Program. At that time, stones were used as opposed to metal, which is what the “shot” is made out of today. The shot, a metal ball (7.26kg/16lb for men, 4kg/8.8lb for women), is put – not thrown – with one hand. (1981). 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 throwing arm will tuck across the individuals body, this will help them to stabilise. The Shot Put can be broken down to four different phases. 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. A biomechanical comparison of the rotational shot put technique used by males and females (Order No. Shot put phases Shot put comprises four phases: The following instructions assume the athlete is a right-handed thrower. 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. Put the Shot at the same time, very late and very fast. The shot put event originates from heavy stone throwing competitions in England and Scotland during the 15th century and was included in the first modern Olympiad of 1896 in Athens. During the ¯ight phase, the shot is essentially a projectile in free ¯ight and so its trajectory But it really begins from the back foot, then hips, then the arms, and finally the wrist. Step 2 - ‘Glide’ The main objective of this step is to maintain and transfer momentum through the body. Then, cup the shot with your fingers and thumb along the back of … The angle of release is a significant factor during this stage that has been determined prior to the shot. Xfinity. Put simply, speed dynamics refers to the changes in the individuals speed whilst they are going through the movements (Zatsiorsky et al, 1981). To execute successful movement in shot put the individual needs to have a solid stable base of support. The phases are the Shot grip and placement, delivery of the shot, power position, and the glide position. 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. scapula must work in concert with humerus to maintain glenohumeral stability; the entire throwing motion takes approximately 2 seconds. List of some of the major dominating Asian countries include China, Saudi Arabia, Thailand, India, Kazakhstan, Korea etc. Speed dynamics. Analysis of Shot Put Throw Nikala Westbrook KIN 417.002 Spring 2015 References Taylor, C. (2007). A push-like movement pattern helps control the accuracy of shot, however, a limitation is speed (Blazevic, 2010). 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. We not play on teaching the rotational shot put. Since its introduction to modern Olympics in 1896, the popularity of this sport grew exponentially in different nations. 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 phases of the shot put were as foll ows: the first double support pha se is from . Using the arm only, push the shot out, ensuring that the elbow is kept high. %PDF-1.5 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). <> Although there are many different factors that are important to success and performance related to the shot put … <> Both athletes in this case study are using the glide technique. 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). The shot put should lightly brush their neck. It can be seen in figure 1.4that movement happens in a sequence, first the individual bends and extends their knee, they begin to rotate, they take off from the ground, they plant their right then left foot and finally they release. Bend at the back knee - This is important as when this leg is extended it generates power (Blazevic, 2010). Goal One: Shot Put Grip and Placement. Wait to leave – The individual needs to wait until the shot has landed before they can leave the circle. Shot putters have a choice between two techniques, the glide and the rotational (or spin) style. Maximising shot put distance and velocity at the point of release through increasing momentum is of interest to coaches. Glide. • Preparation - The thrower sets up correctly to commence the glide. (2010).Projectile motion. The throwing stance varies in width depending on the technique employed by the athlete. 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. All of the above takes place in an instant. The shot put event originates from heavy stone-throwing competitions in England and Scotland during the 15th century and was included in the first modern Olympiad of 1896 in Athens. For a beginner or untrained individual one significant influence over their ability to perform is their level of arousal (Kerr & Cox, 1991). Starting from these phases, graphs of the tangential velocity of the thrower’s CM and the time taken are described. Skip to main content. This type of movement would be better related to a throw-like movement matter, unlike the gliding technique which suits a push-like movement. Fingers should be placed all close to the shot.
