anatomical analysis of throwing a football

While the contribution of the lower body to the proper execution of a football throwing motion is undisputed, Fleisig and colleagues indicated that a considerable amount of force production results from elbow and shoulder joint flexion (2).

When these actions cannot be performed there is an increased likelihood of anterior instability of the glenohumeral joint [3]. Triceps is also at its greatest activity during this phase as the elbow violently moves into extension and across the body. Cocking - Anterior subluxation, internal impingement, glenoid labrum lesions, subacromial impingement. The tibia and tarsals form your ankle joint, which must stay slightly flexed but rigid when you kick so that no power is lost. Detailed analysis of movement is a complex activity requiring sophisticated equipment. These three muscles work with your quadriceps muscle rectus femoris and are responsible for the majority of the power required for kicking a football. Yessis, M. (1984). Improper stabilization of the scapula may be the cause of the increased risk of shoulder impingement in this phase. The subject was asked to completed a standardized warm-up consisting of a 5-minute treadmill run at a moderate intensity, and a set of dynamic warm-up motions such as high knees, butt-kicks, lunge-and-twist, knee to chest, high skips, lateral slides, tuck jumps, A-skips, and forward lunges. Bookshelf 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). The main muscles responsible for hip flexion are psosas major, psosas minor and iliacus, which are collectively known as Iliopsoas, or hip flexors. 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. Four sequential phases of the football throw were consistently reproduced in the 20 NFL athletes whose throws were reviewed: early cocking, late cocking, acceleration, and follow-through (Fig.. Enhancing foot velocity in football kicking: the role of strength training. An overhead throwing motion is broken down into four phases: loading, arm-cocking, acceleration, and follow-through. {Zbla;. Trapezius, serratus anterior and rhomboids produce high MVIC. Handball throwing motion was found to be analogous to football throwing motion except for a greater humeral rotation (4). The lower body and the core muscles are often forgotten in the football throw. Accessibility 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. found a positive relationship between football kicking performance and individual player strength development (10). endobj The wind-up phase is defined as the initial movement to maximum knee lift of stride leg [3]. 2013 Jun;18(2):369-80. doi: 10.1016/j.fcl.2013.02.012. 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). Three broad areas are covered: (1) the technical performance of soccer skills; (2) the equipment used in playing the game; and (3) the causative mechanisms of specific soccer injuries. Observing and analysing movement To help athletes to improve, coaches and performers need to observe and analyse athletes' movements during performance. The SST approach might be a beneficial method for a quick ball release required in the close presence of the defensive player or during execution of a special play. During these simple movements consider the muscles proximally to distally. Numerical models have been used by researchers to gain a better understanding of football heading biomechanics and methods for reducing head impact response. Descriptive statistics and standard deviations (xSD) were calculated for each of the dependent variables. 4 0 obj 7(z@o"EDZl,FKMT k"l)6tR(F )IEf DN5cF BG5EjY>HhP?< W/o ~{*_^ypX?H!SsW%HWMP##^o5_Z=Pf r+~=&#;3e@~hUCE@dR{+ Zw?tr%]#_ &CD:O#WJ5)fL|G?l0-^1:b">-VCXCZWpQ} 3lP'AAA9WLr1jfrRak)tV+d1`MtH.D/,' *Y#QVa1Yq *'qMDH@+)gXrD&T^G7LW\1zjC`6~xH_BSox 3wr The statistical significance level was set a priori to p<0.05.
