The knees is known as a hinge joint, as it can only bend in on direction when it's bent. while the knees is bending the muscles in the leg are expanding creating a wider stride, when the legs comes back the muscle contracts.
The quadriceps muscles are primarily involved in knee extension.
The muscles involved in hip extension are the gluteus maximus, hamstrings, and adductor magnus.
The primary muscles involved in hip extension are the gluteus maximus and the hamstrings. The primary muscles involved in knee flexion are the hamstrings and the gastrocnemius.
In shot put, major muscles involved are the deltoids, pectoralis major, triceps brachii, and core muscles. The actions of the joints include shoulder abduction and flexion, elbow extension, and trunk rotation. These muscles and joint actions are crucial for generating power and distance in shot put throwing.
The actions skeletal muscles can perform are: flexion, extension, abduction, adduction, rotation, elevation, and depression.
Muscles within the brachium are responsible for the extension of the elbow. These muscles also work for the flexing of the arm as well.
The bones involved in long jump are the femur, fibula, tibia, vertebra, metatarsals, phalanges, ulna, radius, and the humerus. The muscles used in the same activity are the gastrocnemius, glutes, quadriceps, hamstrings, biceps, deltoids, triceps, trapezius, latissimus, dorsi, quadriceps, and the abdominals. It also includes the elbow, shoulder, and hip ball and socket joint, the elbow, patella, and toes hinge joint, and the ankles condyloid and synovial joint. The joint actions are flexion, extension, and abduction.
The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
Muscles involved in pushing hard against a wall include the chest (pectoralis major), shoulders (deltoids), triceps, and core muscles for stabilization and power generation. This action primarily engages the upper body muscles.
Back extension primarily works the muscles in the lower back, specifically the erector spinae muscles.
