What the Amateur Golfer Should Know About the Biomechanics of the Golf Swing

  1. 1. ==== ====Improve Your Golf Swing - Golf Swing Secretshttp://www.51-local-smart-secrets.com/==== ====If youve read some of my articles in the past, we focused a lot on training the body to help youprovide more power, consistency and accuracy to your golf swing.Today, we are going to get a little more scientific.I am going to explain the biomechanics of golf. Biomechanics is the study of human movement.Using this definition in golf, it is essentially studying how the body moves when swinging a golfclub. Biomechanics is the study what the skeleton, muscles, and nerves of the body do whenhitting a golf ball. There are actually folks out there that make a living studying these movements,they are called Biomechanists. And the great thing about golf is that there have been a ton ofscientific studies on the golf swing. In addition, this research has allowed biomechanists to createa model of the "optimal" swing in the sport of golf.All of this research has been beneficial to the golf industry. It has provided club manufacturers,swing coaches, trainers, and players with an abundant amount of knowledge to improve the gamein many areas.Biomechanics of the Golf Swing Stage by StageMost biomechanists break the golf swing down into phases.We will talk about the swing into the following phases: 1) address, 2) back swing, 3) transition, 4)down swing, 4) contact, 5) follow through, 6) finish. I will also relate what the body does duringeach of these phases, which muscles are active, and any additional information applicable tobiomechanical study of the golf swing.The golf swing begins in the address stage. The address stage is the position that the golferplaces their body in to begin the swing. According to Glenn Fleisig MD, the address position is afunctional body position which includes the proper grip and body position. A balanced, "athletic"address position, which is consistent swing to swing, will provide the golfer with the correct startingposition for the swing. Inconsistency in either how the body is set up or with the grip leads toinconsistency on shot to shot. The body in terms of muscle activity is fairly low at address. Themuscles of the body are supporting the body in a specific anatomical position and preparing it toswing a club.The back swing (take away) is when the body begins to move the club. The back swing is theportion of the swing that places the body in the correct position to begin the downswing. During theentire back swing the body begins the recruitment of energy that will be transitioned at the top of
  2. 2. the back swing towards the ball. Key points from a biomechanical analysis of the back swing are:as the club moves backwards shear force is applied to anterior portion of the right foot, at thesame time a posterior shear force is applied to the left foot (Fleisig, Biomechanics of Golf). This isthe beginning of torque development in the body that will be transitioned into the club head atimpact. Rotation of the knees, hips, spine, and shoulders continues during the back swing creatingadditional torque to be translated into the club head in later stages of the swing. The importantpoint to remember in the back swing is that the entire rotation of these body parts occurs aroundan imaginary axis of the body. EMG activity is moderate during this stage of the swing as a resultthat the body during this portion of the swing is essentially creating/storing energy that will bereleased towards the end of the swing.The completion of the back swing is what is termed the "transition" stage of the swing. Thetransition point of the swing is where the body finishes its backward movement and begins theforward movement of the swing. The best reference point of when the transition stage of the swingbegins is when weight shift onto the inside of the right foot (right-handed golfer) is completed andmovement back towards the left foot begins. The transition in terms of a time frame is very shortand is completed when weight transfer begins to move forward, and the club completes itsmovement backwards. Research states that the transition of the swing is where additional elasticenergy is stored within the body. This is a result of the lower body moving forward and the upperbody still "coiling" backward. Studies show that at the completion of the transition (top of the backswing) the hips are closed to approximately 45 degrees and the shoulders are closed to about 100degrees (Fleisig, Biomechanics of Golf).After completion of the transition, the down swing into impact begins. Weight shift continues duringthe down swing. The generation of torque is created in the lower body and then transitioned upthrough the body into the club and eventually the club head. According to Fleisig, the majority oftorque in the swing is generated by the lower body muscle groups of the glutes, hamstrings,quads, and core region (low back, abdominals, obliques). The torque created in the lower bodycreates acceleration in the upper body as energy is transferred into the club head. EMG studiesindicate that there is moderate activity of the pectoralis major, latissimus dorsi, and rotator cuffmuscles (Geisler, Kinesiology of the Full Golf Swing) during the downswing. The downswing iscomplete at the point in which impact occurs with the golf ball.Impact with the ball occurs for approximately half a milli-second (Fleisig, Biomechanics of Golf).The purpose of impact is to hit the ball in the correct direction with the chosen amount of force bythe golfer. At impact the weight transfer is complete. Shear force from both feet are towards theintended target. Research indicates that at impact the left foot (right-handed golfer) is supporting80% to 95% of the golfers weight (Fleisig, Biomechanics of Golf). Impact again occurs for a veryshort amount of time (.0005 seconds). Impact is the point at which the potential energy created bythe body during the back swing, transition, and down swing is transferred into the club and clubhead. The potential energy created by the body is then transferred into kinetic energy as club headcomes into contact with the ball.After contact, the impact stage of the swing is complete and the follow through stage begins. Thefollow through is essentially the deceleration of the body after contact with the ball has been made.This is completed through the body rotating to a completion point where the club head is behindthe golfer. Deceleration by the body occurs as a result of the absorption of energy back up throughthe kinetic chain of the body. Follow through is where the body slows itself back down and
  3. 3. dissipates all the kinetic energy create by it, which was not delivered into the ball.SummaryAs you can see, the golf swing is directly connected to the body. And it is the body that generates,directs, and delivers energy to the golf ball. Limitations in the body in terms of flexibility, muscularstrength, endurance, or power can create limitations in the swing from a biomechanicalperspective. In addition, mechanical inefficiencies in the swing itself limit the potential and kineticenergy outputs of the body.
