Swing flaws and body limitation characteristics: Reverse spine angle

The reverse spine angle swing flaw is evident when the player demonstrates a lean of their upper body toward the target. For a right handed golfer this would be to their left at the top of their backswing. 

This lean of the upper body toward the target is a key characteristic of the reverse spine angle.

Shot Implications

This position makes it very difficult to properly sequence your downswing. The proper kinematic sequence is for the hips and pelvis to begin the movement of the downswing followed by the upper body, arms, and finally the hands and club. This allows for the energy stored in the muscles of the trunk to be released in such a way that maximizes power into the ball. If this sequence is abnormal then power is bled from the swing and increased forces can be put into the body. This position also makes it difficult to find the proper path of the golf club as it travels toward the ball, which leads to inconsistency in the path of your ball toward your selected target. 

A SHANK IS WHEN YOU HIT THE BALL MORE TOWARD THE HOZEL OF THE CLUB.

Body Factors

In order to maintain your spine angle during the backswing your body has to be able to do certain things. First, you have to be able to separate your upper body from your lower body. If you are unable to do this it could be because of a mobility issue ( joint stiffness, or muscular tightness). Another reason why you may not be able to separate your upper body from your lower is because of what is called a motor control/stability issue. This is when your body must be trained in how to properly move.

Mobility in the thoracic spine (upper part of your back) as well as your hips are critical during your backswing. If mobility in these areas is limited your body will lean and sway to compensate. This compensation is the reverse spine angle swing flaw. This position puts a lot of stress on the right side of your low back. 

Mobility and flexibility are shown here, but don't try this as a warm-up before your golf round.

Stability in the core and around the hips is critical to efficiently move and properly sequence your swing. We know stability is an issue when we test you using the TPI screen and other exam techniques. Working on strengthening the core and looking at your rolling patterns is a way that we help to train your stability. 

Exercises

Try this exercise to ensure you are keeping your pelvis in neutral. This is another body issue that can cause you to extend or arch your back which then puts you in a reverse spine angle position.

Swimmers, Why Do Your Shoulders Hurt?

All of those dedicated hours in the pool to get ready for your next big meet. Have you ever wondered why your shoulder hurts when you swim? I am going to write a series of blogs discussing some of the causes of shoulder pain in swimmers and what you can do about them. 

Shoulder Impingement

Anatomy of the Shoulder

Anatomically the shoulder joint is a very unstable joint. I equate it to a golf ball sitting on a golf tee. The ball is the head of your humerus (upper arm bone) and the tee is the glenoid fossa ( socket which is part of the scapula or shoulder blade). The shoulder relies heavily on ligaments, muscles, and cartilage to help provide stability.

Impingement Explained

Impingement is when the humerus glides upward and causes stress on structures that sit under your acromion (part of your shoulder blade). There are a lot of pain sensitive structures that lie under this subacromial space, namely your rotator cuff musculature and your bursa sac. The rotator cuff is the musculature that helps to perform certain movements of the arm and shoulder blade as well as what helps to provide stability to the joint. A bursa sac is a fluid filled sac that helps to dampen forces and helps the shoulder joint move more freely. During the recovery phase or above water portion of the swim stroke the arm is going into a flexed and internally rotated position. This position along with the force of the water during hand entry puts a lot of stress on the shoulder joint and its surrounding structures. 

The supraspinatus muscle (shown below) and its tendon are often affected in impingement of the shoulder.

This muscle plays a key role is stabilizing the head of the humerus to prevent it from migrating upward into the acromion. This muscle along with others are susceptible to fatigue as the swimmer's practice progresses. This is where performing specific dry land training exercises helps to strengthen and build the endurance of those muscles. 

Try this exercise: It has shown a large level of contraction in the supraspinatus muscle. Make sure you are using a weight that you can perform 2-3 sets of 15 to 20 repetitions. Don't raise your arms straight ahead, but angled out slightly.
