Once your arms are parallel with the ground, slowly and in a controlled manner lower the weights back down to the starting position. While it is believed that optimal use of the kinetic chain will maximize performance and reduce the risk of injury (6,11), the transfer of force and energy to the small segments and tissues of the upper extremity do place them under great stress.

Modern Tennis Forehand Ebook She holds a Bachelor of Business Administration from Temple University. It is anticipated that coaches will be able to provide a safer yet more productive and effective strength training regimen for their athletes. Background:The open stance forehand has been hypothesized by tennis experts (coaches, scientists, and clinicians) to be more traumatic than the neutral stance forehand as regards hip injuries in te. Using the upper body to lean forward toward the action just before the legs add their contribution is also the same way that players move to ground strokes.

You use the muscles of your lower body to twist into your swing to put more force behind the ball. http://www.researchgate.net/publicaination_and_forehand_drive_velocity_in_tennis, http://www.cpaqv.org/cinesiologia/artigos/muscle_coordination_tennis.pdf, http://www.ncbi.nlm.nih.gov/pubmed/25123001, http://www.ncbi.nlm.nih.gov/pubmed/25120197, http://www.citeulike.org/user/tboats/author/Stossel:TP. As the ball left the racket, only then did the wrist start straightening out and the forearm start pronating. The backhand volley involves slight internal rotation and abduction followed by slight external . Spend as much time as your practice time allows developing movement. Two-handed backhands have larger extension torques in the rear leg, which result in larger axial torques to rotate the hips and trunk than 1-handed backhands (2,10,19). The EMG activity of the subjects' anterior deltoid muscle and the forearm extensor muscle group was recorded with the subjects using racket grip sizes of 4 1/4, 4 1/2, 4 3/4 inches. Repetitive stress injuries caused by repeated motion of the shoulder, such as in tennis. The way to hit a proper forehand back then was to take the racket back with a relaxed but relatively straight arm and only a slightly laid back wrist. Biomechanics of tennis strokes. Inflammation, which can arise beside repetitive injuries or on its own, often in the joints. Keep in mind that: the function of the racket is to enhance the function of the player.

It is best to engage in functional exercises that will strengthen while also keep them loose and flexible. In Figure 5, the athlete is demonstrating a closed stance catching position. The athlete will need to move laterally (utilizing either the shuffle or the crossover step) to catch the MB (loading phase) and then while maintaining dynamic balance produce a forceful hip and trunk rotation to throw the MB. may email you for journal alerts and information, but is committed Dynamic stretching has sustained effects on range of motion and passive stiffness of the hamstring muscles. Finally, biomechanics involves the design and function of equipment. There are 3 planes of motion (figure 1) - sagittal, frontal and transverse. Who do you think hits the bigger FH, her or me?

Keyword Highlighting It is vital that teaching professionals understand this kinetic chain so that they can better recognize errors or inefficient movement. The hand plays an integral role in generating racket speed. When the shoulders are connected well - meaning there is a certain firmness across . The balls that were coming off his racket were fast and heavy like never before. Every time you hit a groundstroke, you're primarily working the transverse plane (i.e. Not because these muscles create a great deal of joint rotation to accelerate the racket (4) or because grip forces increase ball impulse (13), but because the energy from the lower body and trunk must be transferred to the racket in the later stages of the stroke. A typical sign of poor forehand shoulder rotation is the disengaged non-dominant arm, which tends to dangle down alongside the body.
