For Swimmers : Common Injuries, Treatment and Prevention tips
Do you swim leisurely or competitively? If yes, continue to read on.
Recently, one of our physiotherapists, Chng Chye Tuan was interviewed by Style:Men on the common musculoskeletal injuries face by swimmers in the July's issue. Do read on to find out what he has to share.
What are the common problems competitive/regular swimmers face?
The most common swimming injury is the rotator cuff impingement / tendonitis.
- Ball joint of the shoulder compress the tendon against the roof of the socket (acromion) in 2 phases of freestyle – the pullthrough and recovery phase.
- Pull-through phase in the freestyle stroke involves the arm pulling against the resistance of the water. The outstretched arm with internal rotation of the shoulder stresses the tendon and pinched it against the acromion. The pinching can irritate the tendons and give a sudden catching kind of pain.
- The recovery phase involves a body roll and raising the elbow up and out to allow the upper limb to recover out of water efficiently otherwise the shoulder will be working harder at an awkward position to pull the hand out of water.
- Repeated pinching will give rise to inflammation and fraying of the soft tissues.
What are the usual causes?
The usual contributing factors are mainly due to over training, poor technique, poor core muscles and unilateral breathing.
- Over training – when muscles are fatigued, the stabilising component from the rotator cuff muscles becomes compromised thus increasing the chances of the humeral head translating upwards and impinging the rotator cuff tendons. The ball component has to be centralised within the socket of the shoulder to optimise stability and muscle function.
- Technique – the freestyle and backstroke requires the swimmer to roll their trunk such that the drag is minimise and the propulsion force can be maximised. Too much drag will increase the resistence, tiring out the shoulder muscles sooner.
- Strong core muscles and truck control enable the swimmer to do a body roll along the longitudinal axis so that it is easier for the shoulder to pull the upper limb out of water.
- Unilateral breathing can develop a muscle imbalance leading to improper muscle activation and overuse.
What kind of treatments do you recommend?
An assessment of the shoulder girdle, spine and core strength will be performed to be able to properly manage a swimmer’s shoulder.
A key treatment to approach the swimming shoulder is to rehabilitate the rotator cuff muscles to be able to centralise the humerus at different shoulder positions.
Exercises will be prescribed to specifically target these rotator cuff muscles, correcting any imbalances. These exercises include strengthening the weak muscles to improve dynamic support and also stretching exercises to the tight muscles pulling the joint out of position.
As most competitive swimmers will not be able to cease training completely, kinesiotaping complements the rehabilitation therapy by improving the rotator cuff’s ability to stabilise the shoulder joint via better joint awareness from the corrective
Are there preventive measures that swimmers can take to minimise such problems?
Regular stretching exercises, core stability training and work on the techniques. During the early stage of feeling the impingement (catching or pinching) pain, seek help from a sports physician or physiotherapist as soon as possible.
