Static Exertion

Last Updated: August 28, 2020

Definition - What does Static Exertion mean?

Static exertion, also called static loading, is the physical act of maintaining a specific position, posture, or stance for an extended period of time. Different jobs require individuals to perform certain functions where sustained exertion to a localized area of the body can compromise musculoskeletal structures including joints, ligaments, muscles, and tendons.

WorkplaceTesting explains Static Exertion

Protracted static exertion can have serious health implications, such as muscle fatigue with the potential of obstructing blood flow, in turn, decreasing oxygen level distribution in the body. Depending on the line of work, employees can experience circumstances where frequently contracted muscles block essential nutrients while, alternately, preventing elimination of biochemical wastes (i.e. acids). For instance, the use of computerized technology imposes static exertion on the hands and wrists compounded by contact stress with a computer and/or desk surface.

Repeated episodes of this working habit can lead to compressed nerves or carpal tunnel syndrome. As a result, important fine motor skills such as typing become compromised, interfering with a person’s capacity to access, input, and retrieve electronic information for employers. Other industrial occupations involve static loading functions where handling tools or assuming fixed or locked body positions for a long duration of time causes swelling, putting pressure on adjacent nerves.

Employers can apply ergonomic measures to help mitigate and/or prevent the risks of developing chronic musculoskeletal conditions. Individuals with sedentary positions are predisposed to decreased blood circulation and subsequent nerve damage. Comfortable furnishings and/or modified equipment designed for ergonomic support can help with aggravating factors linked to perpetual musculoskeletal issues.
