What is the action of triceps contraction

Triceps brachii contraction refers to the movement of the muscles behind the arm when exerting force, mainly manifested as the tense state of the muscles when the elbow joint is extended or resisting resistance. This type of movement is common in exercises that require arm extension, such as push ups and push ups. The triceps brachii is the largest extensor muscle in the upper limb, consisting of three bundles of muscle fibers: the long head, medial head, and lateral head. When muscles contract, they will pull the arm from a bent state to a straight state, such as pushing heavy objects upwards or keeping the elbow joint locked when doing plank support. Actions such as cleaning windows and pushing doors in daily life also rely on the contraction function of the triceps muscle. The exercises such as neck and back arm flexion and extension, and narrow distance push ups in fitness training can specifically strengthen this muscle group. In special circumstances, the triceps may experience abnormal contractions. neurological disorders such as stroke may lead to involuntary muscle contractions, manifested as persistent stiffness or convulsions in the arms. Long term excessive extension of the elbow joint may also cause compensatory muscle contractions, leading to chronic strain injuries such as tennis elbow. This type of situation needs to be improved by combining physical therapy and neurological rehabilitation training.

It is recommended to scientifically exercise the triceps through a combination of equipment training and self weight training. In the initial stage, you can choose to use an elastic band assisted over the head stretching movement, and gradually transition to equipment compression and other weight-bearing training. Fascia relaxation should be performed before and after training to avoid excessive muscle tension affecting joint mobility. Middle aged and elderly people should pay attention to controlling training intensity to prevent inflammatory reactions at tendon attachment points.
