anatomical analysis of throwing a football

Shoulder injuries to quarterbacks in the national football league. 2 0 obj Although the focus has been more on the shoulder, the entire body movement is required to perform the act of throwing. 3. 2010 Jun;28(8):805-17. doi: 10.1080/02640414.2010.481305. The elbow is a hinge joint formed by the humerus and ulna. x}[6#QhFz/2EfF(Ts"T]E`"2$fiV|9{(gwoao)fLq~77UWbyV~yQ%=6 /KVjxQ4UE^3!r.gW2)pC_@J!Y66? Women's opportunities for competitive physical activity were limited in America until Federal Legislation, commonly referred to as Title IX, became law. PeerJ. :}hK{|p{6CtT)$Vo See the Javelin section for more details. 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. By studying the correlations of the latter with the precision of the shot of the free kick, the aim of this study was to identify the biomechanical variables influencing the accuracy of the direct free kick, while defining the important phases of the execution of the shot of the free kick, in order to provide biomechanical indices to the players and coaches to succeed the direct free kick. The triceps brachii is an agonist in the acceleration part of the throw and an antagonist when the ball is being drawn back. Biceps brachii presents with peak activity during flexion of the elbow in the late cocking phase as it limits anterior translation and compression forces of the humeral head. The data collection instrument is an accuracy test of direct free kick shot on three (03) different positions (Right, Centre, and Left) over a distance of 20m. as shown in the Figure 1. This is the most active phase for the muscles of the shoulder girdle as they work eccentrically to decelerate the arm. Before any testing procedures were conducted, the subject signed an informed consent form. endobj Brunnstrom's clinical kinesiology. These three muscles work with your quadriceps muscle rectus femoris and are responsible for the majority of the power required for kicking a football. With the arm approximately 90 abduction, 30 horizontal abduction, and 50 external rotation, As the ball is removed from the glove, the centre of gravity is lowered by flexing the knee of the pivot leg and the stride leg gradually extends and moves towards the batter, Its main function is to allow a linear and angular motion of the trunk, which lands directly in front of the pivot leg with the toes pointing slightly in. The acceleration phase begins from the point of maximum shoulder external rotation to the point of ball release. There is a tendency for fewer serious injuries, but more minor injuries, on artificial turf than on natural turf pitches. Is There a Relationship Between Foot Reaction Time and Ankle Frontal Plane Torque in Female Soccer Athletes? Sci Rep. 2022 Nov 2;12(1):18493. doi: 10.1038/s41598-022-21508-6. Much of the power for kicking a football comes from the action of straightening your knee. 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. The biomechanics of kicking in soccer: a review. Direct free kick test and data collection. The phases of an overhead throw consist of a: Each phase will illustrate the definition, injury occurrence rate, and lastly pathological possibilities. The hip's bones are the femur and pelvic girdle, which form a ball and socket joint. 2023 Jan 5;10:1046456. doi: 10.3389/fpubh.2022.1046456. //-->. The momentum of ball has a significant correlation of 0.582 and a rate 34% (p<0.01), the ball kinetic energy has a significant correlation of 0.590 and a rate 35% (p<0.01). The shoulder in baseball pitching: biomechanics and related injuries--Part 1. Tight hamstrings may hamper your kicking ability. The soccer season: performance variations and evolutionary trends. Thus, the purpose of this case study was to analyze kinetic and kinematic components for six of the most commonly used quarterback drop throwing patterns, and to provide coaches and strength and conditioning professionals with essential information to help optimize resistance training program development which can ultimately lead to improvements in in-game quarterback throwing performance. Another important factor that needs to be considered is the amount of time required for completion of the throwing motion. 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 Association of lower limb injury with boot cleat design and playing surface in elite soccer. Biceps brachii and brachialis produces marked eccentric contraction to decelerate the elbow extension and forearm pronation. 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. (2012). Analysis of Sprinting The running leg action occurs in a sagittal plane about a frontal axis and involves the hip, knee and ankle joints. The arm acceleration phase begins at maximum shoulder external rotation and ends at ball release [3]. Cocking - Anterior subluxation, internal impingement, glenoid labrum lesions, subacromial impingement. PMC The Biceps Brachii and supraspinatus are shown to be initiated or excited by these mechanoreceptors and assist with the prevention of anterior instability. 2013 Jun;18(2):369-80. doi: 10.1016/j.fcl.2013.02.012. Throwing times were determined from the initiation of the quarterback drop step to the time point of the ball release. The shoulder is abducted about 90, 10 to 20 horizontally adducted and laterally rotates to about 175. Detailed analysis of movement is a complex activity requiring sophisticated equipment. google_ad_client = "pub-6580312449935063"; You are not required to obtain permission to reuse this article in part or whole. These muscles are called your quadriceps, which are made up of group of four individual muscles -- the vastus lateralis, rectus femoris, vastus medialis and vastus intermedius -- that share a common insertion point at the top of your tibia just below your patella, or kneecap. It required American society to recognize a woman's right to participate in sports on a plane equal to that of men. Although the equipment has mechanical characteristics that can be reasonably well quantified, the player-equipment interaction is more difficult to establish; this makes its efficacy for performance or protection difficult to predict. /* Link Bottom Left */ Available from: Toyoshima S, Hoshikawa T, Miyashita M, Oguri T. Contribution of the body parts to throwing performance. Performance requirements limit the scope for reducing these injuries; alternative methods for providing ankle stability are necessary. doi: 10.7717/peerj.14082. Meister K. Injuries to the shoulder in the throwing athlete part two: evaluation/treatment. Citation2017) estimates that the balls initial velocity = 20.4m.s1 so that the ball travels along its flight trajectory during the free kick shot in a minimum amount of time. The objectives of this study are to identify the biomechanical variables that influence the accuracy of the direct free kick, to determine the important phases of the execution of the free kick shot and the parameters that affect the trajectory of the ball during the direct free kick, and to make the hypothesis that there are correlations and statistically significant contribution rates between the biomechanical variables and the accuracy of the direct free kick. Ground reaction forces may be enhanced with a greater number of drop steps, which may ultimately increase quarterback throwing distance. 2. The posterior shear force of about 400 N, the inferior shear force of 300 N, 1090 N of compressive forces and about 97 N-m of horizontal abduction torque are generated during this phase after ball release. Top Contributors - Vinit Kothekar, Vidya Acharya, Kim Jackson, Olajumoke Ogunleye, Wanda van Niekerk, Rachael Lowe, Naomi O'Reilly, WikiSysop and Claire Knott. a no difference when compared to 1SLR (p>0.05)b greater than 3SSA (p<0.05)c lower than 1SLR, 3SSG, 5ST (p<0.05). Registered in England & Wales No. This type of muscle action is called an isometric contraction, which means that while these muscles are generating tension, they are not causing any actual joint movement but merely hold your ankle in place. Baseball pitching demonstrated a greater and earlier occurrence of upper torso rotation, elbow extension, and shoulder internal rotation when compared to a standard quarterback throwing motion (3). A question often asked is to identify the Agonist, Antagonist, Fixator & Synergist Muscles. Perform a kinesiological analysis of someone engaging in a sequential throwing, kicking, or striking skill under each of these force application conditions: momentary contact, projection, continuous application. The shoulder is a ball and socket joint formed between the humerus and the scapula. However, the fundamental analysis of motion can be done visually and should involve the following: The running leg action occurs in a sagittal plane about a frontal axis and involves the hip, knee and ankle joints. eCollection 2022. Abstract and Figures. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). So, because of the increased anterior force on the shoulder, it can be assumed that over time the anterior ligamentous structures to the glenohumeral joint may be compromised. Although there are many types of kick, the variant most widely reported in the literature is the maximum velocity instep kick of a stationary ball. For a right-handed pitcher, throwing arm is the right arm, a gloved hand is left, lead/stride leg is left lower extremity and pivot/stance leg is right. 1 0 obj Hinge joints allow flexion and extension only. The direct free kick is an integral part of football and is considered a crucial skill, especially for those who attempt to score goals, such as strikers and other attackers (Bray and Kerwin, Citation2003). HHS Vulnerability Disclosure, Help Unable to load your collection due to an error, Unable to load your delegates due to an error. The ipsilateral leg and trunk rotate approximately 90 and the contralateral hip and knee flex [5]. During the initial movements, the pitcher brings his or her hands overhead and lowers to chest level. When looking at analyzing a goalkeeper dive, one important technique which can be used would be using motion analysis. Simulation studies suggest the importance of ball mass, ball speed and player mass in affecting the severity of impact. Understanding which muscles do the work can help you set up your training regimen to throw the football harder and farther. The shoulder muscles are heavily involved in the throwing motion in football, first to support the arm and then during the motion and follow-through. Following seven joint angle changes corresponding to all these degrees of freedom were obtained throughout the throwing motion. Register to receive personalised research and resources by email. During this phase, the trunk is perpendicular to the batter and upper extremity position is finalized. %PDF-1.7 Due to the high forces generated in this phase, the posterior muscles are highly susceptible to tensile overload, undersurface cuff tears, labrum and bicep pathologies, capsule injuries, and internal impingement [3]. The .gov means its official. It is concluded that there are still many features of the game of soccer that are amenable to biomechanical treatment, and many opportunities for biomechanists to make a contribution to the science of soccer. .KO'Bu~dn"x=>l7B@ktTmx`6j>bR * Penalty feet positioning rule modification and laterality effect on soccer goalkeepers' diving kinematics. During these simple movements consider the muscles proximally to distally. It is reported that about 50% of the velocity of the ball during an overhead throw is generated from step and body rotation. Yessis, M. (1984). Name and discuss anatomical and mechanical factors that apply to representative throwing, kicking, or striking activities. The wrist forms a condyloid joint between the ulna and carpal bones.

The wind-up phase is defined as the initial movement to maximum knee lift of stride leg [3]. This paper will present a history of women's involvement in sport prior to the federal legislation enacted to eliminate sexual discrimination in education and sport. This almost rectilinear trajectory lasts until the balloon is slowed enough for gravity to drop it, giving rise to truncated parabolas. People also read lists articles that other readers of this article have read. Nonetheless, it is always a crucial part of the game, as it is the main objective of the defense. National Library of Medicine Biomechanics of the elbow in the throwing athlete. This site needs JavaScript to work properly. Prior to 1870, activities for women were recreational rather than sport-specific in nature. When kicking the ball then: If you quote information from this page in your work, then the reference for this page is: agonists, antagonists, synergists & fixators, Gluteal muscles (gluteus maximus and gluteus minimus) and Hamstrings (biceps femoris, semimembranosus, semitendinosus), Quadriceps group of muscles (rectus femoris, vastus medialis, vastus lateralis and vastus intermedialis), Hamstrings (biceps femoris, semimembranosus, semitendinosus), Gluteal muscles (gluteus maximus and gluteus minimus), A description of the actual actions which occur at the joints involved, The plane(s) in which the movement occurs, The type of contraction (isotonic - concentric or eccentric, isometric), The range of the muscle action (inner, middle, outer). Teres minor presents with its peak activity during this phase as it resists anterior humeral head translation, horizontal adduction and internal rotation. This is explained by the negative correlation between ball speed and accuracy. 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. Front and back leg knee angle variables represent the internal angle formed between the thigh and shank segments with the fulcrum located at the center of the knee joint (Figure 4). Am J Sports Med. 4 0 obj (1996). Kinematics deals with the position, velocity, and acceleration of a moving object. Unauthorized use of these marks is strictly prohibited. Submitted by: Richard C. Bell, Ed.D., J.D. Kelly, B.T., Barnes, R.P., Powell, J.W., & Warren, R.F. These factors can potentially elicit a negative effect on kinetic chaining synchronization (optimal contraction sequence of neighboring joints and segments) and ultimately impair throwing performance (2,9). Coupled with the arm cocking phase this phase has also been hypothesized to be at increased risk of various shoulder injuries due to the high kinetic energy generated from the lower extremities [3][11]. Moreover, it seems that the larger the number of drop steps the quarterback takes, the greater the rear foot ground reaction forces. Greater throwing arm elbow extension may be induced as biomechanical adjustment due to lack of force production caused by the inability of the quarterback to take a greater number of drop steps. The statistical significance level was set a priori to p<0.05. Figure 4. Previous research found that quarterbacks have five times greater chances of injury when compared to the offensive lineman and linebacker playing positions, with the most injured sites being the knee, wrist, and ankle joints (1). Houglum PA, Bertotti DB. ]]QFZi6c/R_{YT^[^GDLQy;T['({'(o7Z~'v'wTvR3sIkW+&GWayjSy9dTjVXdNlE 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. Previous research indicates that an athletes ability to achieve proper joint alignment and optimal eccentric muscle forces during the cocking phase of the throwing motion can augment the concentric phase of the motion (2,9). Flexion - bending a joint. Subscapularis produces significant eccentric contraction as the humerus passes neutral rotation to control the lateral rotation of the arm. However, there are few scientific data substantiating these concerns in terms of the biomechanical head response to impact. Following is the list of potential shoulder injuries in different phases of pitching[1]. Greater throwing arm elbow extension may be induced as biomechanical adjustment due to lack of force production caused by the inability of the quarterback to take a greater number of drop steps. Biomechanics of baseball pitching A preliminary report. They were noncompetitive, informal, rule-less; they emphasized physical activity rather than competition. Effect of core training on skill-related physical fitness performance among soccer players: A systematic review. Considering that the quarterback throwing motion requires full-body motion involvement, we may assume that these physiological improvements would ultimately lead to throwing performance enhancement. Kinematic variables for the examined quarterback throwing approaches. You need lower-body strength in order to kick a football. (2011). Adickes, M.S. Follow-through is the phase where the body continues to move forward until the arm has ceased motion. The large muscles of the legs and lower body, such as the calves, quadriceps, hamstrings and glutes, all help to drive and provide power as you step into the throw. Peak left leg force for the 3SSA was lower when compared to 1SRL and 1SLR. Scand J Med Sci Sports. They use this data to monitor progress and. Recognised disadvantages include the need for . @^dW%wJ(WYV|CVjqx+~sT>~2-9W^oJKTR5n85ut>u|eI1l{5c!CRf PD9yBE$O wv^Rz$XA2CIW*rq|OwF&,`gA9`AeNQ!z 3 0 obj Kicking a football -- either a round soccer ball, oval American or rugby ball -- uses a lot of muscles and joints. Football kicking is described as a complex motor skill consisting of six important steps: Approach angle, supporting leg forces, swinging of the striking leg, hip flexion and extension at the knee level (Alcock et al. Our results indicate that the majority of ground reaction force production required for an optimal quarterback throwing motion comes from the rear leg, and the magnitudes may reach three times bodyweight forces. In most cases Physiopedia articles are a secondary source and so should not be used as references. Simultaneously the pectoralis major, subscapularis, and serratus anterior are inhibited. FA Davis; 2012. Here the target centre was at eye level (166 11 cm). When these actions cannot be performed there is an increased likelihood of anterior instability of the glenohumeral joint [3]. A successful kick requires good eye-foot coordination, balance, accuracy, skill and power. When a quarterback drops back to throw, commentators and fans often analyze the pass and the quarterback's arm strength. The large arm muscles of the triceps, biceps and forearm are involved in the throwing motion, especially once you begin the throw. Escamilla et al state that a shoulder compressive force slightly greater than bodyweight is generated to resist shoulder distraction, while a posterior shear force of 40-50% of body weight is generated to resist shoulder anterior subluxation. 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. Triceps is also at its greatest activity during this phase as the elbow violently moves into extension and across the body. The knee bones involved are the femur and tibia, which form a hinge joint. A biomechanical analysis of the soccer throw-in with a particular focus on the upper limb motion. Throw velocities are reported as the value in miles per hour (mph) displayed on the radar gun. AlTaweel A, Nuhmani S, Ahsan M, Abualait T, Muaidi Q. PeerJ. Before Dx\UhrGhL)jt34j Although not evident in these data, it is likely to be apparent when making realistic throws on an actual field. Goalkeeper landing with the ball hitting the ground first. Descriptive statistics and standard deviations (xSD) were calculated for each of the dependent variables. Youth football injuries. }?,BUxa3Q}Zkv)5y=kJOL]xMf7o?/4(&Z u+Y[oY5Qmi;hL]wP_D&|zZnli]O|q:?upmx3Y&oj\9ljp5WD[W2JUVLEH t=AA~06/6uvV[M&p( ZLR`\J5*vQVt(:-u[/V,QOT=4LA?31VeW'5bPr!Hcgz:k[e @zXSO$?LU.H~Tf`#TDR1Zh 2F(81$.djZ. Available from: I give my consent to Physiopedia to be in touch with me via email using the information I have provided in this form for the purpose of news, updates and marketing. Young, W.B. This is because an increased angled approached allows the hip of the striking leg to rotate more, causing a larger striking surface area of the foot, and therefore a faster ball speed and/or improved accuracy. Biomechanics of pitching with emphasis upon shoulder kinematics. The main muscles responsible for hip flexion are psosas major, psosas minor and iliacus, which are collectively known as Iliopsoas, or hip flexors. stream official website and that any information you provide is encrypted Kicking, a fundamental motor skill usually acquired during childhood, can be . Kicking is predominately a lower-body activity but your whole body is involved in maintaining balance and stability. This difference may be mainly caused by a greater stride length and time allowed for completion of this body motion. Available from: Scotty Gilbertson. This analysis reviews the kinesiology of a quarterback's throwing motion specifically. a greater than all others (p<0.05)b lower than all others (p<0.05), except 1SRL. A Sport-specific Performance and Prevention Program for the Throwing Quarterback. It is an important phase which is responsible for imparting the velocity which is driven to the point of ball release. Baseball pitching demonstrated a greater and earlier occurrence of upper torso rotation, elbow extension, and shoulder internal rotation when compared to a standard quarterback throwing motion (3). The bones of the knee involved are the femur and tibia which form a hinge joint. Loading power moves The trunk continues to rotate and tilt, and energy transferred through upper extremity. Biomechanics of overhand throwing with implications for injuries. Cocking phase is further divided into (a) early cocking and (b) late cocking. The wrist is in neutral and the elbow is elevated to about shoulder height and is 90 flexed. eCollection 2022. The last regime is that of rotating balloons that leads to circles or even pieces of spiral when the distance traveled is large enough. The quarterback position in American football plays a major role in the overall team success and the level of their performance can potentially determine the final game outcome. During this phase, a varus torque of about 64 N-m is generated at the elbow and about 67 N-m internal rotation torque is generated at the shoulder. The results revealed that there are correlations as well as statistically significant contribution rates between the accuracy of the direct free kick shot and the biomechanical variables of the various component phases; the approach phase: the player approach time has a statistically significant correlation of 0.616 and a rate of 38% (p<0.01), the player approach distance has a significant correlation of 0.638 and a rate of 41% (p<0.01), the player approach speed has a significant correlation of 0.483 and a rate of 23% (p<0.01).
