Physiotherapists in Wakefield treat many different conditions including the issues profiled below.

Muscle Fibre Types

Muscle has three main fibre types which are specialised for different functional abilities. Type 1 muscle fibres, also known as slow twitch fibres, have a good capillary supply and use a mostly aerobic energy system. Type 2 fibres use a non-aerobic energy system more typically and in general the proportion of Type 1 to Type 2 fibres is fixed genetically in an individual. Muscle cells don.t turn over like many other body cells, the muscle continues for the life of the person. Muscles get larger and stronger by the individual muscle cells gaining mass and the number of muscle cells does not change.

Muscles are very adaptive tissues and can respond to altered work demands very much more quickly than other tissues, enabling us to build up the ability to do something new in a short time. The way the muscles are exercised has strong effects on the way muscles adapt to the new stresses. If endurance training is performed, with lower weights and higher repetitions, the largest changes are in the Type 1 slow twitch fibres which exhibit increases in their blood supply and in the enzyme systems which deliver energy. This allows these muscle fibres to contract for longer periods without tiring.

The Shoulder

The human shoulder is a design of great functional ability and ingenuity, designed entirely around placing our hands in the places we want them to be. The hand is the tool with which we connect with the world and we need to be able to place it in a great variety of positions so we can manipulate objects. The shoulder contributes to a very large extent to our ability to do this and to achieve this goal it has an extremely large range of motion permitting great flexibility. However, in satisfying the requirement for flexibility it sacrifices stability.

To allow the large range of motion the shoulder is designed with a relatively small socket and a very large ball, the head of the arm bone. The shoulder capsule, the fibrous ligamentous bag which surrounds and supports the joint, is relatively lax and contributes little to stability. The nervous and muscular systems have the job of keeping the large humeral head balanced on the small glenoid cavity (shoulder socket). The large shoulder muscles are more concerned with gross movements of the shoulder, and it is the rotator cuff muscles which perform much of the stabilising work of the joint.
