any muscle having three heads, or points of attachment, but especially the triceps brachii at the back of the upper arm. One head originates on the shoulder blade and two on the upper-arm bone, or humerus. Uniting part of the way down the arm, the heads swell into the belly, or muscle proper. This tapers to a tendon that rounds the elbow and attaches to the ulna, the larger of the two forearm bones. Since contraction of the triceps straightens the arm, the muscle is called an extensor. It also helps lock the elbow when the forearm pushes forward against resistance. The triceps works in coordination with a flexor muscle, the bicepsbiceps
, any muscle having two heads, or fixed ends of attachment, notably the biceps brachii at the front of the upper arm and the biceps femoris in the thigh. Originating in the shoulder area, the heads of the biceps merge partway down the arm to form a rounded mass of tissue

 brachii of the upper arm.



a muscle that arises from three heads. The triceps muscle of the arm, situated on the posterior surface of the humerus, extends the forearm at the elbow joint. The triceps muscle of the calf is at the back of the leg below the knee; it consists of the two-headed gastrocnemius muscle and the one-headed soleus muscle, and it flexes the foot at the ankle joint.

Habitually shod RFS runners who employ a MFS or FFS may over-exert their triceps surae during novice barefoot running, inducing localized muscle fatigue.
We hypothesized that novice barefoot runners would exhibit fatigue to the triceps surae in response to exertion, resulting in altered lower-extremity movement patterns and a reduced ability to attenuate impact.
The triceps surae (I) and rectus femoris (S) muscles were readily available to produce either ankle plantar flexion or rapid hip flexion to drive the COM posteriorly.
When looking at the triceps surae muscles collectively within the leg the normalization values for each muscle were summated and then used to normalize the summated EMG values of each muscle during the task.
Concentric contraction of the triceps surae muscles causes plantar flexion of the ankle from neutral position (0[degrees] plantar flexion) to 30[degrees] plantar flexion, limited by a fixed mechanical stop under the pedal.
However, while a limitation, the intention of using a musculoskeletal model here was to investigate the changes in kinematics, triceps muscle length and Achilles tendon loading in order to assess the impact of altered ankle kinematics on triceps surae mechanics during the flexed and extended knee of the exercise.
