Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another.. In biomechanics and strength training, ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [1]
The range of motion describes the total range of motion that a joint is able to do. [5] For example, if a part of the body such as a joint is overstretched or "bent backwards" because of exaggerated extension motion, then it can be described as hyperextended.
Joints are classified both structurally and functionally. [4] Joints play a vital role in the human body, contributing to movement, stability, and overall function. They are essential for mobility and flexibility, connecting bones and facilitating a wide range of motions, from simple bending and stretching to complex actions like running and ...
A multiaxial joint, such as the hip joint, allows for three types of movement: anterior-posterior, medial-lateral, and rotational. A multiaxial joint (polyaxial joint or triaxial joint) is a synovial joint that allows for several directions of movement. [9] In the human body, the shoulder and hip joints are multiaxial joints.

Stride range of motion: the leg's integrated path between stance onset and swing offset. Joint angles: Walking can also be quantified through the analysis of joint angles. [10] [11] [12] During legged locomotion, an animal flexes and extends its joints in an oscillatory manner, creating a joint angle pattern that repeats across steps. The ...
A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint. The rotation of the crank drives the linear movement the slider, or the expansion of gases against a sliding piston in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset. In-line
Movement demands include strength, endurance and range of motion. Training oversights occurs when the body is overused. [9] Internally, the joints, muscles, tendons, and ligaments can affect one's flexibility. As previously mentioned, each part of the body has its own limitations and combined, the range of motion can be affected.
This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments. The bones provide stability to the body. Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints.
