If you watch a paddler with good technique you will see the following:
· The bodies large muscles doing most of the work
· Relaxation of the muscles not engaged during the effort
· Structurally sound body mechanics
These points are all intertwined and play an equal part in good technique. It's important to not only observe what you are doing but also to feel what you are doing while paddling. Without one of these items the others will, in time, fail and injuries or strained muscles will occur.
Rotator cuff injuries or strain
Coaches should be careful not to advocate technique that exposes athletes to injury. One of these injury causing movements is having the top hand above the head exposing the top shoulder to injury. Moving the arm up and down at the shoulder is asking for an injury involving the rotator cuff. Take the time to consciously look at yourself objectively while you are paddling. Where is your uper hand through the stroke? Can you draw on the above points during your stroke? Observation is key to improvement. You must observe and process to change.
The rotator cuff muscles control rotation of the shoulder. These muscles are put under a great deal of strain especially when your arm is above your head repeatedly. The rotator cuff is a group of muscles which work together to provide the shoulder joint with dynamic stability, helping to control the joint during rotation (hence the name). Due to the function of these muscles, sports which involve a lot of shoulder rotation – for example, dragon boating, outrigger paddling, kayaking, etc. – often put the rotator cuff muscles under a lot of stress. (notes from sports injury clinic).
While you are paddling concentrate on your shoulder and arm and feel what they are doing. Are they moving up and down instead of locking into your core and being an extension of your back. Watch the person ahead of you on the boat. What is their shoulder and upper arm doing during the stroke? Your shoulder should be down at all times and therefore providing a strong extension of your large back muscles to plant, pull, and move the boat forward.
