3 Tips You Need to Know to Keep Swinging

We asked our Wellness Practitioner, Chiropractor, former Professional Tennis Player and four-time Canadian Junior National Champion, Dr. Dominique Harmath, for some of her tips for staying pain free on the courts.

Feeling the Weight of the Serve on Your Shoulders?

The average speed of the first serve in professional tennis players ranges between 182-190km/h for men and 155-161km/h for women, with shoulder rotational angular velocities in the acceleration phase of the first serve exceeding 2,500 degrees per second (1,2). These are impressive stats.

What Goes Fast, Must Slow Down.

In this case, it must slow down very quickly to prepare for the return coming back. The deceleration forces acting on the shoulder in the follow through phase of the serve can reach up to 300 newton metres with distraction forces registering 0.5-0.75x a person’s body weight (3).

On average, a player hits 40 serves per set with a 3:1 first to second serve ratio (4). Take that in. Now add the fact that the shoulder is the most mobile joint of the human body (5). Never really considered addressing your shoulder health as a tennis player? I hope I’ve caught your attention.

So what can you do to make sure your shoulder can keep up with your big serves?

1. Have a Mobility Program

Mobility in the Functional Range Conditioning (FRC) framework means a combination of flexibility and control/strength. You want to develop body awareness and motor control in individual joints, in this context the shoulder, to optimize its health and movement. If we are only stretching, we are missing a piece of the puzzle. We want usable movement that we can apply load to. Stretching alone does not ensure that our shoulder has the capacity to actively move with control in that range.

A full body mobility program including the thoracic spine, hips and ankles should also be in place as these are the building blocks of the sequential multi segment movements that occur during serving.

An example of a shoulder mobility exercise that can be performed daily is controlled articular rotations (CARs). Shoulder CARs involve moving the shoulder in a circular, slow, and controlled manner with high effort through its maximal ranges of motion. It does not have to be complicated, but there needs to be intent and commitment. Building tissue resilience takes time.   

2. Strength Train for Tennis

Once we have muscular control in various ranges, we want to train the shoulder to have the capacity to withstand the forces it must transfer and generate. Sounds great. How about some push-ups? Not so fast. During the service motion, the shoulder only contributes about 13% of the kinetic energy (6). It does however transfer a significant amount of the energy that was generated from the legs and trunk to the hand (6).

If there is an energy leak from the trunk or legs, other structures higher up in the sequenced service motion (i.e., the shoulder) will have to compensate to attain the same serving velocity (6). This means our strength programs should be focused on much more than some push-ups. We need a full body strength program that prepares you for the physical demands of tennis.

3. Listen to Your Body

If there is fatigue, pain, or discomfort you need to acknowledge it and adjust what you are doing to give your body the attention it needs to recover. What is the best recovery? That is a topic for another day but keep in mind that you know best how your body feels so practice being in tune with it. You are the one person who will be affected by the environment, training, and recovery you create for yourself.  

The court is calling.
