Summary
Performing push-ups with a neutral wrist protects the wrist and elbow from injury by altering force distribution. This finding allows for tailored training protocols to prevent upper extremity injuries.
Area of Science:
- Biomechanics
- Kinesiology
- Sports Medicine
Background:
- Push-ups are a common exercise for upper body strength and evaluation.
- Extended wrist push-ups can lead to wrist, elbow, and shoulder injuries, limiting participation for those with prior injuries.
Purpose of the Study:
- To compare elbow and shoulder joint movement patterns during neutral versus extended wrist push-ups.
- To hypothesize differences in force transfer between the two push-up styles for training protocol adjustment.
Main Methods:
- Fourteen healthy males performed push-ups with neutral and hyperextended wrists.
- Motion capture technology (Vicon) tracked upper extremity kinematics.
- Force plates measured ground reaction forces.
Main Results:
- Shoulder and elbow joint loading and movement patterns differ significantly between neutral and extended wrist push-ups.
- Neutral wrist push-ups result in less elbow movement and load, and more shoulder movement and load compared to extended wrist push-ups.
- The direction and magnitude of joint forces vary between the two push-up styles.
Conclusions:
- Push-up style significantly impacts upper extremity joint kinematics and kinetics.
- Neutral wrist push-ups can protect the wrist and elbow from ligamentous injury.
- Understanding these differences enables customized strengthening, treatment, and rehabilitation programs for various athletic demands.

Muscles that Move the Forearm
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Muscle Coordination and Action
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.

Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
