when performing a movement, as the body takes the path of least
resistance. This means that as the muscles surrounding the shoulder
joint get tired your shoulder position will be compromised.
Lack of flexibility is a very common problem, with many people
having tight pectoralis minor and major, latissimi dorsi and upper
trapezius. As these muscles are used in pulling, pushing and overhead
movements, they experience a large amount of overuse. When these
muscles are tight they worsen the kyphotic thoracic spine posture,
making it difficult for the individual to put their arms overhead without
extending through the thoracic spine. This means that at the end of
the range of the movement, i.e. when you are hanging and swinging
under the bar, you are performing an end of range stretch against
your whole body weight, which is a huge load to put through the
joint. In addition to this, reduced flexibility results in inhibition and
weakening of the scapular stabilisers, such as the lower trapezius
and serratus anterior.
What can we do to prevent injuries?
Encourage clients to have a postural assessment with a good
physiotherapist, and have their general posture and flexibility assessed.
