Tensiomyography (TMG) is a measuring method for detection of skeletal muscles' contractile properties. [1] Tensiomyography assesses muscle mechanical response based on radial muscle belly displacement induced by a single electrical stimulus. [2] It is performed using the TMG S2 system.
Electromyograph: An electromyograph measures muscle activation levels through the use of electrodes which are either placed on the muscle in the form of pads, or inserted into the muscle in the form of needles. It is able to measure muscle activation levels for isometric holds as well as for presses and pulls.
There are various ways to measure physical strength of a person or population. Strength capability analysis is usually done in the field of ergonomics where a particular task (e.g., lifting a load, pushing a cart, etc.) and/or a posture is evaluated and compared to the capabilities of the section of the population that the task is intended towards.
The parallel muscle architecture is found in muscles where the fibers are parallel to the force-generating axis. [1] These muscles are often used for fast or extensive movements and can be measured by the anatomical cross-sectional area (ACSA). [3] Parallel muscles can be further defined into three main categories: strap, fusiform, or fan-shaped.
A better estimate is provided by the total area of the cross-sections perpendicular to the muscle fibers (green lines in figure 1). This measure is known as the physiological cross-sectional area (PCSA), and is commonly calculated and defined by the following formula, developed in 1975 by Alexander and Vernon: [4] [5] [6]
Strength training also requires the use of proper or 'good form', performing the movements with the appropriate muscle group, and not transferring the weight to different body parts in order to move greater weight (called 'cheating'). An injury or an inability to reach training objectives might arise from poor form during a training set.
Additionally, stretching the chest muscles and strengthening the back muscles can also help improve posture. [47] Exercises that strengthen the back muscles include rows, pull-ups, and shoulder blade squeezes. Exercises like doorway stretches for the chest can help stretch out tension that contributes to rounded shoulders.
An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs.
