The correct answer is: d. forceful exertions
When you twist while lifting a heavy box, you are combining two risky movements: lifting a heavy object and twisting your body. This combination puts a significant amount of force on your musculoskeletal system, particularly your back.
Forceful exertions refer to activities that require a lot of physical effort, like lifting heavy objects. When you twist your body while lifting, it can lead to overexertion of your muscles and improper alignment of your spine, increasing the risk of musculoskeletal disorders (MSDs) such as strains, sprains, and even more serious injuries like herniated discs.
To prevent MSDs, it's important to use proper lifting techniques, which include keeping the object close to your body, bending your knees instead of your back, and avoiding twisting while lifting. This helps distribute the weight more evenly and reduces the strain on your muscles and spine, decreasing the risk of injury.
