Muscles and tendons (a tendon is the fibrous tissue that attaches muscle to bone in the human body) can become too weak which will lead to them not being able to stabilise the joints anymore. (This can quickly become a challenge for the joints which, in turn, might also, be affected.) Weak muscles will mean they will deliver less endurance and are more susceptible to injury.
When there is excessive stretching of a muscle or tendon resulting in pain, soreness and inability to use normally it’s called a strain. Signs of strain: pain, muscle contraction or tremor, and loss of strength.
How do muscle and tendon injuries occur?
Causes of strain are excessive use, pull or stretch of tissue affected. Strain may come about suddenly or develop from chronic use or overuse.
A typcial tendon injury is Tendovaginitis (inflammation of the sheath of the tendon) from overuse, or tendinitis.
Swelling, moderate hematoma, pain at weight bearing.
