The angle of release is a significant factor during this stage that has been determined prior to the shot. Put the Shot at the same time, very late and very fast. Basic Shot Put Technique (Shot Put Learn-By-Doing) by Mark Harsha, Portage High School Girls' Head Coach. Place it under your jawbone, and extend your other arm in the direction of your throw. How it works. The shot is then placed under the chin with the elbow held high. Goal One: Shot Put Grip and Placement. endobj
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. Dish. 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 Are throwers will either throw starting in the power position or the glide position. Shot putters have a choice between two techniques, the glide and the rotational (or spin) style. MR26202). 4 0 obj
Maximising shot put distance and velocity at the point of release through increasing momentum is of interest to coaches. The individual is applying force to the ground with their bent knee, the ground then will apply an opposite force which is sent up through the body and into the throwing arm as the shot is released (Blazevic, 2010). 24-42). This type of movement would be better related to a throw-like movement matter, unlike the gliding technique which suits a push-like movement. x��ko�8�{��~� +��kQ�����n��}X�%V��R+�8��� EҖd��L����p�:��������/ފ�էz9�fy�����L�y{.�\�|����Ĉ�ۗ/�H�JdJE!�T\}{�"s���k!������O�9Uzr5=Փ�S3����9����.�����J'�饙�������տ^�xX &n�4�2+�����-e��s�T�*��q�D����x�e.=��x�����+Y�[T�3�s���4���z���7���f�>7@�4�z�F:��}���b'�Gq�mzj&K���13y��G������fQ�\�`����i���%�|Ҭ`���&_�,�����T������d�&�z㬣dL��R.Ӳ2�@��@

The most obvious answer here is 45°, at this angle horizontal and vertical velocity are equal and the shot has the ability to reach is maximum distance (Blazevic, 2010). — Starting Monday, Missouri is in Phase 1B, Tier 2 of its COVID-19 vaccine rollout plan. The shot is held at the base of the fingers, not the palm. These require that force be applied to the grou nd in order to produce momentum and velocity. Analysis of Shot Put Throw Nikala Westbrook KIN 417.002 Spring 2015 References Taylor, C. (2007). The spherical shot is made of metal. (2006) Seated Shot Put – What’s it all about? Basic Shot Put Technique (Shot Put Learn-By-Doing) by Mark Harsha, Portage High School Girls' Head Coach. Shot Put comes under the track and field job event. 3 0 obj
Playing next. The vast majority of the time beginners will utilise a gliding technique, this is less technical and easier to understand. As the individual extents the force moves into the arm as the shot put is released. (2010).Projectile motion. There is a big debate surrounding how speed should be utilised during the build up to the shot. A push-like movement pattern helps control the accuracy of shot, however, a limitation is speed (Blazevic, 2010). These factors will then be examined throughout the three biomechanical phases; preparation, execution and follow through. Shot Put. 2. Two putting styles are in current general use by shot put competitors: the glide and the spin. Holding the shot put. (304788526). The men’s shot weighs 7.26 kg (16 pounds) and is 110–130 mm (4.3–5.1 inches) in diameter. In simple terms the shot needs to be released between 90° and 0°, however, it is up to the individual to determine what is best (Blazevic, 2010). Please select below. Shot put drills such as: arm strike, reverse stand throws, A drill, stand throws, and full throws using a glide technique. In this case, we have to concentrate upon two aspects very carefully and they are − 1. The following is a blog that examines how biomecahanical factors influence shot put. 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. %PDF-1.5
A temporal analysis of the put was made and the throwing action was divided into six phases. Put the shot at the base of your fingers, then hold the shot at your neck with your elbow bent and parallel to the floor. 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). Athlete’s need to maintain the shot put velocity gained from the first phase set up. Zatsiorsky, V. M., Lanka, G. E., & Shalmanov, A. A biomechanical comparison of the rotational shot put technique used by males and females (Order No. This will enable them to build speed as they swing around (Blazevic, 2010). Track and field quarterly review, 93(3), 18-29. Santino Logan. wind up (see below); cocking; acceleration; deceleration; follow-through ; Biomechanics. Fingers should be placed all close to the shot. Step 2 - ‘Glide’ The main objective of this step is to maintain and transfer momentum through the body. 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.

To execute successful movement in shot put the individual needs to have a solid stable base of support. Shot put phases Shot put comprises four phases: The following instructions assume the athlete is a right-handed thrower. ATHLETICS OMNIBUS - SHOT PUT From the Athletics Omnibus of Richard Stander, South Africa 1. HLPE3531 Skill Acquisition and Biomechanics for Physical Educators. endobj
Although you need strength to throw a shot put, technique and form are much more important than muscle definition. 6 years ago | 234 views. That is now a metal not softer than brass. 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). Bartonietz, K.

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. Biomechanical analysis of shot putting technique. scapula must work in concert with humerus to maintain glenohumeral stability; the entire throwing motion takes approximately 2 seconds. I have used the same sequence to introduce shot put to small groups and also individuals. To begin, stand sideways at the back of the 7 foot circle you’re throwing from. Log in. How to Do the Shot Put Glide Technique. Put simply, speed dynamics refers to the changes in the individuals speed whilst they are going through the movements (Zatsiorsky et al, 1981). What is the optimum angle of release and release height? The shot put should lightly brush their neck. 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. When you’re ready to throw, explode up into a standing position while you twist your body so you’re facing the target. Most world-class male throwers, including 2009 World champion Christian Cantwell, employ the rotational shot put technique. The shot, a metal ball (7.26kg/16lb for men, 4kg/8.8lb for women), is put – not thrown – with one hand. COVID-19 Vaccination Recommendations. In order to attain the maximum projectile range the individual needs to determine the best angle release. These factors include: These factors will then be examined throughout the three biomechanical phases; preparation, execution and follow through. 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. 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. 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). �'�9�KV�6,,I"�*��m�0=-Y�f�G���q�|�.�-@:��А����ijİA��^"�ِ���4��)�x�A�˙�SSMМ�vs8 � ���cqRF�����Mw���n�O�8ga�1��

What biomechanical factors contribute to success in shot put? In this case, we have to concentrate upon two aspects very carefully and they are − 1. 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. In 2014 Asian Games, Speed dynamics. Early shot put events were judged on the distance the stone, or shot, could be thrown from behind a raised wooden board following a short run-up of no more than seven feet. While the rotational technique is an outstanding way to propel a shot put a great distance, it’s not for everyone. For a beginner or untrained individual one significant influence over their ability to perform is their level of arousal (Kerr & Cox, 1991). (1981). Shot Putt Training Program. 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. And how do these factors influence the way the movement will be conducted? 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 execution of the shot put performance follows a push-like movement patter, this means that all of the parts of the kinetic chain are moving simultaneously (Blazevic, 2010). Both athletes in this case study are using the glide technique. Since its introduction to modern Olympics in 1896, the popularity of this sport grew exponentially in different nations. Keywords: athletics, projectile, release angle, shot put, sports biomechanics. 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).
