anatomical analysis of throwing a football

(PDF) A biomechanical analysis of the soccer throw-in - ResearchGate Scand J Med Sci Sports. 2012 ), foot contact with the ball, and follow-up (Barfield 1998 ), the kicking procedure can also be divided into five essential It is an important phase which is responsible for imparting the velocity which is driven to the point of ball release. It occurs from the point of ball release to maximal humeral internal rotation and elbow extension. Epub 2013 Aug 13. Figure 4. The purpose of this study was to analyze kinetic and kinematic components for six of the most commonly used quarterback drop throwing patterns and determine how further performance improvements can be made. A biomechanical analysis of the soccer throw-in with a particular focus on the upper limb motion. The arm cocking phase can be defined as the beginning of lead foot contact and ends at maximum shoulder external rotation [3]. This is the most active phase for the muscles of the shoulder girdle as they work eccentrically to decelerate the arm. 2 0 obj The graphical representation of the six quarterback throwing approaches examined in this study is presented in Figure 1. It is known that team sports like football are very complex because of the parameters they bring into play. However, the SST throwing arm elbow magnitudes were significantly greater when compared to the rest of the throwing approaches. Players adapt to surface types over a period of several games. During this phase, it is vital to maintain scapular stabilization due to the forward acceleration of the arm which is equivalent of a peak internal rotation angular velocity of approximately 6500/sec near ball release. No difference was observed for ball speed, non-throw arm elbow angle, front leg knee angle, and back leg knee angle between any of the examined throwing approaches. Brunnstrom's clinical kinesiology. People also read lists articles that other readers of this article have read. During these simple movements consider the muscles proximally to distally. Cocking - Anterior subluxation, internal impingement, glenoid labrum lesions, subacromial impingement. Following is the list of potential shoulder injuries in different phases of pitching[1]. 169-174). This phase begins from the point where the stride leg contacts the ground to the point of maximum external rotation of the throwing arm. google_ad_width = 160; Mechanical Analysis of an American Football Tackle - Academia.edu This data can be used by strength and conditioning professionals to obtain a better insight into quarterback kinetic and kinematic throwing performance requirements and serve as a guideline for optimal choice of resistance training exercises, especially considering that peak ground reaction forces can reach a magnitude of approximately three times subjects body weight. Kelly, et al. (1996). Thus, the smaller elbow flexion observed for the SST approach might be initiated by biomechanical adjustments necessary to make up for the lack of force production caused by the quarterbacks inability to take one or more penultimate steps such as observed in the one, three, and five-step throwing approaches. Planes and axes of movement - Movement analysis in sport - Eduqas Determining the hip joint isokinetic muscle strength and range of motion of professional soccer players based on their field position. One-way analysis of variance was used to determine the differences between the six throwing approaches for the kinetic and kinematic variables examined in this study. & Rath, D.A. Elbow injuries are the second most common injuries in baseball pitching. Kicking biomechanics: Importance of balance | Lower Extremity Review Its long head origin is the infraglenoid tubercle of scapula, its lateral heads origin is above the radial sulcus, and its medial head is below the radial sulcus and its insertion is the olecranon process of ulna. MOVEMENT ANALYSIS OF ULTIMATE FRISBEE Flexion of Elbow and Wrist Internal Obliques attaches to thoracolumbar fascia, 2/3 of iliac crest & lateral half of inguinal ligament assists in side bending and flexion of the trunk Elbow and Wrist Actions associated with backhand throw MECHANICS : Backhand Throw Middle: Arm Prior to Release EXTERNAL OBLIQUES Peak right leg force demonstrated significantly lower magnitudes for 1SRL when compared to 1SLR, 3SSG, and 5ST. Simulation studies suggest the importance of ball mass, ball speed and player mass in affecting the severity of impact. 7R@r.CNz[%2>FJ:}uK1. They were noncompetitive, informal, rule-less; they emphasized physical activity rather than competition. Monteiro RLM, Bedo BLS, Monteiro PHM, de Andrade FDSP, Moura FA, Cunha SA, Torres RDS, Memmert D, Santiago PRP. {u7~g]NHzyI~hnhy%hqLT08ps2!ln].;S`K2y@?87% EoUvxoGhXJYj :T2{D(W6mFq%m Movement In Joints, Muscles & Bones: Kicking a Football R[ :`YS%? The triceps brachii is an agonist in the acceleration part of the throw and an antagonist when the ball is being drawn back. n%4$(aH:F7nF?l%\Ln12m/DnL_2#}b_erD@AP3+\3Um#@m&&IgNm To allow hip flexion to occur, your three hamstring muscles -- semitendinosus, semimembranosus and biceps femoris -- must relax. Luo S, Soh KG, Zhang L, Zhai X, Sunardi J, Gao Y, Sun H. Front Public Health. While the muscles listed are responsible for the majority of the movements necessary to kick a football, a number of muscles work to hold various parts of your body steady so your kick is delivered from a solid base of support. All of these muscles, combined with the arm muscles, are extremely active during the throw as you prepare to release the ball. Foot-to-ball contact phase: the momentum of the foot has a statistically significant correlation of 0.455 and a contribution rate of 21% (p<0.01), the kinetic energy of the foot has a significant correlation of 0.416 and a rate of 17% (p<0.01). Based in Harker Heights, Texas, Timothy Onkst has been writing about sports, fitness and health since 2003. National Library of Medicine Hip flexion is the largest joint action when kicking a football, because it starts from a position of extension and finishes with a significant follow-through. Adickes, M.S. Kicking is predominately a lower-body activity but your whole body is involved in maintaining balance and stability. Citation2012) claim that the average ball speed during direct goal kick is 28.3m.s1 for a floating ball shot, the speed is 25.8m.s1 (De Luca etal. Using the central trend (arithmetic mean) and dispersion (standard deviation) parameters for the descriptive part, and the calculation of Bravais Pearsons correlation coefficients (r) for the analytical part, the calculations were performed by the IBM SPSS statistics 20 software analysis utility.
