The athlete grasps the handle of a cable pulley machine at the height of the waist. In the upper-body: the muscles of your chest, upper back, shoulders, and arms. Front Cardiovasc Med. Preparation 4. Not only will this program target your specific muscle fibers that generate speed, they will also isolate the exact muscles that are crucial for all aspects of the tennis game. The toss should be positioned in front and slightly to the left of the front foot, and should be impacted at the top of its flight. 2023 BDG Media, Inc. All rights reserved. Jack Groppelis co-founder of the Human Performance Institute. The right non-dominant arm movement is to either move it parallel to the hitting arm throughout the stroke or to tuck it in a bit in the follow-through. The racket was placed on the dominant side; then, it was directed towards the ball. I'm pretty sure I can do double Maria Sharapova's best in any exercise. Bahamonde R and Knudson D. Kinetics of the upper extremity in the open and square stance tennis forehand. Then, in the late 90s, a young and charming Brazilian player named Gustavo Kuerten shocked the world by coming out of nowhere and winning the French Open. 2019;6:69. doi:10.3389/fcvm.2019.00069, Oja P, Kelly P, Pedisic Z, et al. In Figure 1d-f, we can see the forward swing. physiological and biomechanical analysis of the tennis serve, forehand and backhand, as well as a 3D Newton-Euler dynamical analysis of the tennis racket motion during these shots. The purpose was to train the athlete to move efficiently to deep balls behind the baseline and to be able to produce greater energy transfer from open stance position that will translate into greater weight transfer, trunk rotation, and more effective stroke production from deep in the court (Figure 4). In general, there are 2 styles of coordination in 2-handed backhands. Finally, there is a demonstration of how the legs, hips, and torso should move in synchrony as well as instruction on how to develop coordination so the athlete can utilize the kinetic chain more effectively. All they do is hold the racket and snap the wrist I think. Step 9. Muscles shoulders: deltoid, pectoralis major, coracobrachialis elbow/fore: biceps brachii, brachialis, brachioradialis, pronator quadratus & teres hand: flexor digitorum supinators, lumbricals, palmar interossei, opponens pollicis trunk: erector spinae group hips: hamstring group, gluteus medius & minimus knees: quadriceps group tennisinstruction.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com. Polyester strings were more durable and it allowed Kuerten to stroke the ball with as much racket head speed as he could possibly generate. The flexor carpi ulnaris muscle, pronator teres and flexor digitorum superficialis form predominantly the musculo-tendinous unit overlying the AOL; all three muscles have been described to contribute to medial support as secondary stabilisers. I guess it depends on the person? The muscles involved would include: pectoralis major, latissimus dorsi, teres major, subscapularis, and deltoid (anterior fibers). From the sports medicine point of view it is important to consider how the racket dampens vibration and reduces shock. Grip the dumbbells so that they hang by your sides with the palms of your hand facing your sides. Who do you think hits the bigger FH, her or me? The athlete takes 3 to 5 steps from the machine to increase the tension and lowers the body into a quarter squat position. Vigorous axial hip and upper-trunk rotation allow for energy transfer from the lower extremity to the upper extremity in the square stance forehand. Situation-specific forehands refer to the need to produce different types of forehands depending on where the player is in the court, the purpose of the shot (tactics), amount of preparation time available, as well as where the opponent is during the same scenario. Vitamin D and Inflammation: Potential Implications for Severity of COVID-19. Backhand I guess that muscles aren't everything. ; A muscle fiber generates tension through actin and myosin cross-bridge cycling. That is almost all shoulder How do the forearms contribute a lot of power? Professional players and champions of the past utilized the tennis forehand wrist position in a static manner, with the wrist hardly moving throughout the forehand swing. The follow-through is across the line of the body and a recovery step brings the player into the ready position. This lean into the ball tends to level out the racket path, resulting in a longer, more stable hitting zone. Training the wrist extensors is particularly important for tennis players using a 1-handed backhand. 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. Every tennis racket has a grip (or handle) with 8 different sides. In a split step the feet should be shoulder width apart, with legs flexed, the upper body leaning slightly forward and the weight on the balls of the feet. This article has summarized key biomechanical variables inherent in an elite-level tennis serve. What?? (a-f). People think that 90% of the swing comes from hips/legs/core, but the arm is still swinging fast. If you were doing a backhand swing with your racket in tennis, you would be doing horizontal extension (also called horizontal abduction) and lateral rotation at the shoulder joint. The glutes also light up as you swing to return the ball. Keep a loose wrist so when you make contact it meets it dead on. The forehand can be an aggressive and powerful attack shot that is used to return an opponent's shot and, when executed correctly, will manoeuvre an opponent around the court or win a point.. This means that subsequent body parts must work harder. This linked system, or KINETIC CHAIN, works in a very systematic fashion with the legs interacting with the ground. Following impact in all tennis strokes, the racket and arm retain the vast majority of the kinetic energy from before impact, so the eccentric strength of the musculature active in the follow-through should also be trained. Most importantly, a split step must occur just as the opponent is starting the forward swing. You may search for similar articles that contain these same keywords or you may The smooth acceleration and the slinging (or whipping) action is where all the power and spin comes from. Finally, biomechanics involves the design and function of equipment. In addition, every time you hit a forehand or backhand, you work your abdominal muscles, especially the obliques, which run down the sides your torso. During the wind-up for a powerful forehand throw, counter-rotate your shoulders as if you're preparing to swing a baseball bat. BASED ON THE AVAILABLE RESEARCH, IT WAS DETERMINED THAT TRAINING EXERCISES SHOULD EMULATE THE SEQUENTIAL COORDINATION INVOLVED IN GROUND STROKE PRODUCTION, AS WELL AS STABILIZING MUSCULATURE THAT MIGHT BE INVOLVED IN DEVELOPING FORCE OR IN PROTECTING BODY PARTS FROM STRESSFUL ACTIONS. The pronounced hip and shoulder rotation from Figure 1c-f is evidence of the use of angular momentum. When the shoulders are connected well - meaning there is a certain firmness across . (a-f) One-handed backhand groundstroke-(a-c) illustrates the preparation phase of a 1-handed closed stance backhand, while (d-f) illustrates the forward swing. Ariel GB and Braden V. Biomechanical analysis of ballistic vs. tracking movements in tennis skills. As the shuttle is struck behind the body the 'thumb' grip (often confusingly referred to as a backhand grip) should not be used. (a-f) Forehand groundstroke-(a-c) illustrates the preparation phase of the open stance forehand, while (d-f) illustrates the forward swing. For the forehand specifically, the core and forearms are most important. For example: When hitting the serve the legs may not be utilized completely, resulting in the hips and trunk working harder to create arm and racket speed. 9. And that means youll be quicker on your feet both on and off the court. In fact, the preferred style of grip and height of the ball at impact used by the player significantly affects the potential contribution of the hand/wrist rotation to racket speed (4). Aerobic exercise: Top 10 reasons to get physical. An essential ingredient of footwork is to think of the body as a series of small, coiled springs that, when activated, sequentially result in propelling the player in the desired direction. Eccentric strength both in the upper and in the lower body can assist in maximizing tennis performance as well as to aid in the prevention of injuries (12). When I train my forearm, the next day the racket feels lighter Why would it be all shoulder?? All rights reserved. Research focused on police officers' decision-making in ambiguous use-of-force situations has yet to investigate the role that a suspect's biological motion plays in unknown-object identification. 2013;21(3):E219-E228. What Women Need to Know. His swing style on the forehand featured a western grip and a follow through that ended by wrapping way past his left side so that his right shoulder was pointing toward the net with the racket head behind him. Several reviews of the biomechanics of tennis are available for interested readers (5,15,18). The program conditions for speed the muscles used in all of the following: One handed forehand; Two handed forehand; One handed backhand; Two handed backhand; Tennis . This focuses stress on the medial elbow region in the bent-arm sequential coordination in these strokes. There may be times when the execution of a serve is altered based on the environment - wind, sun, a noisy crowd. 2015;63(10):2014-22. doi:10.1111/jgs.13667, Umberson D, Montez JK. 516-409-4444 It's characterized by pain from the elbow to the wrist on the inside (medial side) of the elbow. Tennis players need to create differing amounts of force, spin, and ball trajectories from a variety of positions, and this has resulted in adaptations of stroke mechanics and stances. Each one of these sides is called a bevel, and they are numbered from 1 to 8 for easier identification. Effective analysis of this kinetic chain is an essential ingredient in developing technique in stroke production and in determining the possible cause of an injury. Biomechanics of tennis strokes. The backswing requires an increased shoulder rotation on the backhand volley as the racket has to move to the opposite side of the body. This article will summarize recent research related to the biomechanics of tennis technique and propose specific conditioning exercises that logically would tend to improve performance and reduce the risk of injury in tennis. Assuming we're talking about a modern fh, I will respectfully disagree with this post. Iwata M, Yamamoto A, Matsuo S, et al. But why were the videos showing otherwise? 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. J Am Geriatr Soc. Ultra-heavy topspin drivers like Rafael Nadal as well as flatter power hitters like Novak Djokovic took the tennis world by storm. Please try again soon. Tennis also requires a high amount of agility, flexibility, quick reflexes and aerobic and anaerobic conditioning. 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. Forward rotation of the upper trunk coincides with a lag in the upper extremity resisted by eccentric muscle actions and large peak shoulder horizontal adductor and internal rotation torques (3). Beth Rifkin has been writing health- and fitness-related articles since 2005. Like the tennis serve. Forward movement of the upper arm is a key feature of forehand mechanics, producing 30% of the racket speed. Furthermore, there is peak activity of the gastroc and quadriceps towards the end of this phase. Medicine ball wall open stance groundstroke drill. According to Nelo Phiri, a tennis coach at Life Time Westchester, the action of swinging a tennis racquet fires up your ab muscles. Is it the deltoid, shoulder? The serve is the most strenuous stroke in tennis and deserves critical analysis. No stretching, no icing, no light weights, no ball squeezing, no work with a flexible bar, no pulleys. There are three major causes of shoulder pain: Direct damage (trauma) to some part of the shoulder bone, muscle, or other tissue. How to Improve as an Outside Hitter in Volleyball. Once the weight is lowered as far as possible, the athlete then flexes and extends the wrist to lift the weight back up to the starting position. Squatting and staying low is often necessary for quick anticipation and explosiveness, says Phiri. Given a modern fh, the key point is that if you are using the muscles in your forearm to create power or spin then you are not swinging correctly. A players positioning, and how he or she uses the ground is vital to stroke production. This phase involves the trunk muscle to make the adequate momentum and cancelation. Takahashi K, Elliott B, and Noffal G. The role of upper limb segment rotations in the development of spin in the tennis forehand. The game of tennis has changed dramatically in the past 30 years. Place your wrist against the handle. TennisInstruction.com. One aspect of inefficient movement is when one of the body parts is left out or the kinetic chain is broken. How to reconcile this with other posts claiming that the power comes from pushing off the ground? Here is what strength training can do for tennis players of all levels and shapes and sizes. Its not every day you think about the forearm muscles, but they come in clutch when playing tennis. All games of tennis consist of six basic strokes: the serve, forehand groundstroke, backhand groundstroke, forehand volley, backhand volley, and the overhead smash. This ground action force is necessary to decelerate the body from one direction and accelerate the body in another direction. Luckily, these muscles respond quickly to training, unlike legs, which are a b$%# to train. Mili uses various swing exercises to help players feel the swing and how to amplify it through the body movements. 16. J Back Musculoskelet Rehabil. Although the movement begins in your legs and travels up through the core, your upper body is responsible for the final execution and follow through on the shot. Step 11. Whatever the technique adopted, the strength and conditioning professional should work with the tennis coach to customize training programs for the specific techniques used by players. With the right technique you not only win a lot of points, but also save valuable energy in the match. If the analysis of inefficient movements is followed, it can be of great assistance in locating a problem in stroke production. The forehand specifically relies on the pectorals, deltoids and biceps to provide much of the upper body and arm activity in a tennis stroke, with the forearm and wrist "following along for the ride" after the hips open and generate internal shoulder rotation. The upper back, chest, shoulders, biceps and triceps all come into play during a tennis swing or tennis serve. By subscribing to this BDG newsletter, you agree to our. Most players change grips during a match depending on what shot they are hitting. The legs take the force and add to it by transferring the force to the hips, from the hips force is transferred to the trunk, from the trunk to the arm, and from the arm to the racket. ; isotonic: A muscular contraction in which the length of the muscle changes. 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. To understand how your players develop coordinated skills, control, consistency, placement and power, it is important to consider the idea of a linked system of body segments. For example, MB drills are offered to help the athlete, not only move and get in position properly but also to execute the form of the stroke in the proper pattern. The forehand tennis stroke is made with the dominant hand. For example: Some players have a hitch in their service motion. Counter-rotating your shoulders should make your hips want to turn with your shoulders. This concept indicates that the speed of the racket is built by summing up the individual speeds of all participating segments. Broadly considered, human musclelike the muscles of all vertebratesis often divided into striated muscle (or skeletal muscle), smooth muscle, and cardiac muscle. In the end, the role of the wrist on the tennis forehand was there all the while, but for a long time, it was just attributed to the wrong part of the swing! Tennis demands movement in all of these planes - and at times, multiple planes simultaneously. When playing table tennis, muscles such as calf muscles, ankles, hamstrings, lower back, rotator cuffs, deltoids, triceps, and biceps are trained the most, even when the whole body really is active during an intense game. From this position, the athlete slowly rotates through the transverse plane as far as the athlete's flexibility allows. There are 3 planes of motion (figure 1) - sagittal, frontal and transverse. In the modern tennis forehand, pro players today are hitting the ball with much more power and topspin than ever before. For example: When the two handed backhand is hit with no trunk rotation the arms must swing harder, increasing the chance of an error. The open stance in forehand is not new as this was used in men's tennis championships. While theres a lot of emphasis on your lower body and core in a game of tennis, your upper body, arms, shoulders, and chest are key components, too, says Frayna. It hones in on the larger muscle groups listed below. Ajay Pant, senior director of racquet sports, TJ Mentus, ACE-certified personal trainer, Trainers Reveal How Long You Should Rest Between Sets, How Many Squats Should You Do? You use the muscles of your lower body to twist into your swing to put more force behind the ball. The follow through was straight forward in the direction of the ball then wrapping slightly around the front past midpoint but not totally all the way over the shoulder or torso. Please enable scripts and reload this page. That tells us that the left shoulder (for right-handed players) is disconnected from the right shoulder, and therefore they do not rotate together as the forehand is being hit.. Work these muscles on and off the court and youll have Wimbledon-level tennis abilities in no time. The athlete starts about 5 to 8 feet from a solid wall and loads the hips and core while also putting the oblique muscles on stretch. Lift your legs straight up toward the sky. 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. Both these movements are used during tennis groundstrokes. You must log in or register to reply here. The rotations of the upper arm, forearm and hand account for the remaining 80 percent of racket speed. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist. Kinetic chain contributions to elbow function and dysfunction in sports. For a forehand volley, slight external rotation and slight adduction followed by abduction of the shoulder allow the player to complete the stroke. While moving forward, backward and side to side, your core helps you make quick changes in direction. When watching a game, youll notice that tennis players are holding a squat pretty much throughout the entire game. 2017;51(10):812-817. doi:10.1136/bjsports-2016-096822, Donnelly JE, Honas JJ, Smith BK, et al. Here's What Trainers Say, Here's How Long To Spend In An Ice Bath To Reap All The Benefits, Get Even More From Bustle Sign Up For The Newsletter. What is it? Besides improving your flexibility, the racquet-based sport trains an assortment of muscles, too. This gets all of the big muscle groups connected through the shoulders, back, core and hips in position to fire. Elliott B, Takahashi K, and Noffal G. The influence of grip position on the upper limb contributions to racket-head speed in the tennis forehand. I understand the theory, but in the real world, the forearm muscles get a hell of a workout in high end tennis. What kind of muscles are used to hit the tennis ball? Tennis volleys require smaller muscle and joint movements than either groundstrokes or serves. to maintaining your privacy and will not share your personal information without A motion analysis system was used to collect the motion trajectories of the shoulder, elbow, and wrist joints and the trunk. Training exercises should, therefore, emulate this sequential coordination, as well as stabilizing musculature. Due to the swinging of the racket, tennis is often thought of as an upper-body sport, but your leg muscles, including your glutes, quadriceps, hamstrings and calves, are doing most of the work out on the court. The next sections will summarize recent research on technique issues specific to each groundstroke that are important to consider when planning conditioning programs. Playing tennis will help strengthen your legs, but if you are a serious player, consider adding additional leg exercises to your workout routine such as squats, lunges and step-ups. Vigorous extension of the lower extremity in classic closed stance forehands creates greater axial torques to rotate the pelvis and hips than not using the legs (9). Mayo Clin Proc. Theyre also required to accelerate and catch up to the ball, he says. This means that subsequent body parts must work harder. One way to remember which muscle is the agonist - it's the one. The purpose was to develop rotational core strength in the transverse plane (Figure 8). Evidence from a Nationally Representative Survey. A typical sign of poor forehand shoulder rotation is the disengaged non-dominant arm, which tends to dangle down alongside the body. In this guide we will go through the individual steps with you to bring your forehand to a new level. 20. While performing a two-handed backhand stroke, the racket was held with a . Knudson D and Blackwell J. She holds a Bachelor of Business Administration from Temple University. SPECIFIC EXERCISES BASED ON THE FINDINGS IN THE RESEARCH LITERATURE WERE THEN OFFERED. Efficient deceleration: The forgotten factor in tennis-specific training. The three most commonly used conventional grips are: the Continental (or "Chopper"), the Eastern and the Semi-Western. Also a few exercises that tennis players should do. Forward axial torque to rotate the hips achieves its peak at the initiation of the forward stroke (8). This adaptation is partially the result of technology changes in the tennis racket and strings allowing for more power and spin generation resulting in more margins for error on the strokes. Inclusion of these key training exercises in a tennis player's . you're rotating). The forehand is the weapon for most tennis players and building a game plan behind a powerful forehand makes winning matches much easier. Some error has occurred while processing your request. The backhand underspin has an impact point that occurs closer to the front foot and closer to the body. You need to start your forehand swing with it facing somewhat downward in order for it to end up at vertical as it meets the ball. The athlete flexes and extends the wrist to lower the weight. Your racquet face naturally opens up (tilts upward) as you swing forward. The purpose was to increase grip strength and endurance via forearm flexion and extension (Figure 9). To improve your grip strength, squeeze an old, squishy tennis ball. Youll feel it when serving, doing forehand or backhand swings, and whenever you make quick movements around the court. 9. Agility, balance and strength all come from your core your lower back and stomach muscles which is used during every shot and movement during a tennis match. The flexible racket has been shown to dampen the shock better. Step 10. The world's best players like Roger Federer, Rafael Nadal, Juan Martin Del Potro and Stan Wawrinka use the forehand as a powerful weapon. At impact the racket shoulder moves more toward the net than the topspin stroke. He was using a new kind of string made of polyester, instead of the traditional natural gut. National Institute of Arthritis and Musculoskeletal and Skin Diseases. Both these movements are used during tennis groundstrokes. ; eccentric: An isotonic contraction where the muscle lengthens. In order to build up maximum racket head speed at contact, it has to be moving continuously even after contact. 10. Generally, this grip is used by players when they are playing in a tennis court that produces low ball bounce such as grass court. Let me clarify how I understand rotations on a modern FH: The way I use the term "core rotation," I include not only the abdominal and torso region but also the hip joints. February 5, 2020. There are differences in the use of the legs, trunk, and upper extremity between the 1- and 2-handed backhands. While this transfer of energy has not been tested in open stance forehands, it is logical that vigorous leg drive also transfers energy to trunk rotation. Other players simply keep the non-dominant arm dangling down next to the body from the start to the finish of the forehand. Hit the back of the ball if you want to lift it to get the forehand high loop. It's not theory. Unless you are very weak, you are not going to find a bigger FH in the gym. From the sports medicine point of view, when a player is out of position, it is difficult to use the body properly in generating force to hit the ball which means that the upper arm must work harder than it should. Much of the power in the volleys comes from this step. Perform two to three sets of 10 reps with each exercise and work both arms. Additionally, the power for your serve, forehand and backhand originates in the legs and travels up through your body to your racket. Following is a biomechanical look at the four basic strokes: Forehand, backhand, serve and volley, as well as footwork. Figure 10a demonstrates a forearm pronation movement, and Figure 10b demonstrates a forearm supination movement. THE PURPOSE OF THIS ARTICLE WAS TO SUMMARIZE RECENT RESEARCH RELATED TO THE BIOMECHANICS OF TENNIS TECHNIQUE IN GROUNDSTROKES AND THEN TO RECOMMEND SPECIFIC STRENGTH AND CONDITIONING EXERCISES THAT WOULD TEND TO IMPROVE TENNIS PERFORMANCE AND PREVENT INJURY.
