Which physical risk factor is defined as how often a task is performed within a short period of time?

• A. Repetitive Motions
• B. Awkward Postures
• C. Forceful Exertions
• D. Static Load

Answer: (A)

The risk factor being described is the frequency at which a task is performed in a short period of time. Repetitive motions involve performing the same movements many times in quick succession, which can prevent muscles and tendons from recovering between cycles and lead to cumulative microtrauma over time. This is why repetitive motions are linked to conditions like tendinitis or CTS in jobs that cycle rapidly, such as data entry, packaging, or assembly work. Awkward postures refer to non-neutral body positions that place stress on joints, which is a separate dimension of risk. Forceful exertions involve high muscle effort or lifting heavy loads, increasing fatigue and injury risk through different mechanisms. Static load means holding a posture or carrying a load without movement for an extended period, which also stresses the body but in a different way.
