Omitting the human factor and ergonomics fitting the workplace to the worker from designs has compromised the safe and efficient production, operation, and maintenance of equipment and facilities, both in the military and civilian sectors, leading to injuries and damage to equipment as well as costly retrofits. Designs that disregard the basics of human physical characteristics and cognitive abilities can be associated with inefficient and costly operation and maintenance and with the injury or even fatality of the user.
The answer to this question is complex. While back belts do indeed provide additional support to the lower back during heavy or strenuous tasks such as liftingthey do not eliminate the risk exposure.
Many people who wear a back belt misunderstand the protection a back belt offers. It is common practice for individuals who wear back belts to lift heavier items that they would not normally consider lifting. This false sense of protection may actually result in an increased risk of injury.
Abdominal and core muscles, when engaged, act as an internal stabilizer for the low back, reducing the risk of injury when lifting. When back belts are worn properly tightened only during the strenuous part of an activitythe chances of the belt weakening your core muscles are minimal.
Studies have shown that the use of back belts can result in reduce back muscle activity. It is possible that prolonged use of a belt can cause weakening of the lifting structures of the back, however additional research is necessary. A simple answer is "It depends on the back support".
Most back belts and supports have no effect on lumbar motion or posture. Some of the more rigid belts especially those with the contoured lumbar insert can alter movement patterns, improving lower back postures and body mechanics.
Be warned, however, that the stresses can be transferred to other unsupported areas of the body and may lead to an increased risk of injury there. Many believe that back belts are a good tool for increasing worker awareness during lifting, thereby reducing the likelihood of risky mechanics or behavior.
It is good practice to remind employees that back belts do not make them stronger and they should not attempt to lift things they wouldn't normally lift.
While back belts can serve as a safety reminder, they are only one component of safe lifting. Using sound ergonomic principles, proper body mechanics, and attempting only those tasks within your physical capabilities can help you avoid injury.
Wear your back belt whenever necessary, but as little as possible.
Tighten your belt only during the strenuous part of an activity. For light tasks and breaks, loosen the belt.
Avoid the "Superman Syndrome". Back belts should not replace good physical condition.Relevance to industry. Our literature review failed to find any systematic analysis that addressed the tightness of abdominal belts, we focused on examining the effect of belt tightness on the psychophysically determined lifting abilities in this study.
Ergonomics is the branch of ergonomics dealing specifically with the office environment.
In recent years the main focus of office ergonomics has been on computer work due to the rapid increase in computer use in the modern office and the associated increase in injuries.

The paper reviews research on the use of abdominal belts for industrial back injury prevention programmes. The evidence for biomechanical, physiological and psychophysical effects of belt use is. Belts increase flexibility.
Belts can help to keep muscles warm. Warmer muscles are more flexible than colder muscles. Belts serve a biofeedback function. The presence of a back belt can help remind workers to use proper body mechanics when lifting. Experts questioning the value of back belts have the following concerns: Belts elevate blood pressure.
