Study finds regular short breaks can prevent muscle fatigue and injuries in manual workers.
- “Microbreaks” could break the cycle of workplace fatigue and injuries, according to a new study.
- It would be recommended to take a minute break every 10 minutes.
- Simply resting or stretching during this one minute break are equally effective.
In manual occupations such as material handling, inappropriate lifting or excessive strain while working is one of the main causes of musculoskeletal disorders. The University of Alberta could have a solution to reduce these diseases that affect joints, muscles and even tendons. Short breaks of one minute every 10 minutes should be taken to reduce physical fatigue and the risk of injury within the company.
Musculoskeletal disorders: resting 1 minute every 10 minutes reduces injuries
For this study, researcher Karla Beltran measured participants’ fatigue in a laboratory by having them move boxes while tracking their muscle activity and movements using body sensors. The volunteers were divided into three groups: those who performed the task without a break, those who rested one minute every 10 minutes, and those who stretched at the same frequency.
“We observed a significant reduction in muscle fatigue between the different work-rest schedules”specifies the author of the article, published in the journal Sensors. “Taking small breaks during a shift can significantly reduce muscle fatigue and potentially reduce the risk of work-related musculoskeletal disorders without negatively affecting productivity.”
She adds that in terms of recovery, there was no difference between stretching-based microbreaks or simple rest. Both methods were equally effective.
Micro-breaks: they should be promoted within companies
Given the results obtained, the researcher recommends promoting micro-breaks within companies to limit employee fatigue and injuries. The study suggests that small changes to the workplace — whether on a construction site, in a factory or in a warehouse — can be easily implemented at no cost to the employer.
“It’s just about talking to your employer and making a small change to your company culture”assures Karla Beltran in a communicated. “The more they start doing it, the more everyone will eventually see the results.”
