Implementing a pre-shift stretch and flex program is a fairly common practice in the construction industry, but there are differing opinions on whether or not it serves to effectively prevent workplace musculoskeletal disorders. This study, conducted by researchers from the University of Wisconsin-Whitewater and Central Washington University, provides a clear, statistically significant conclusion that stretch and flex programs are shown to reduce OSHA recordable injuries and lost workdays as well as workplace musculoskeletal disorders. Note that one of the study authors has an impressive background of education and work in Oregon!
Another type of pre-shift physical preparation, known as dynamic warm-ups, has risen in popularity as an alternative/companion to static stretching programs. This article from the Cleveland Clinic discusses the pros and cons of dynamic warm-ups versus basic static stretching: Dynamic Stretching vs Static Stretching (clevelandclinic.org). The takeaway is that for common construction activities, it may make sense to start the day with a dynamic warm-up and end the day with a static stretching cool down.
In addition to the benefits of injury prevention that a dynamic warm-up or stretch and flex routine may provide is the opportunity it gives site supervisors to evaluate fitness for duty. It is reasonable to conclude that workers who are unable to participate in pre-shift warm-ups may also be unable to perform work safely that day. If you have a pre-shift stretch and flex program or dynamic warm-ups in place, make sure your site supervisors/foremen understand they are expected to evaluate the crew as they warm up for the work that day. This simple preventative step can save your company and employees from unnecessary risk and potential injury in multiple ways.
As the title suggests, stretch and flex programs upgrade the fitness of your business and provide a competitive advantage over companies who have chosen not to implement such programs.
