Boomers Beware! The “Mighty” Old

Senior_on_exercise_bike_mediumWhile the average age of your workforce is probably over 50, many of the jobs in your company were designed for a younger crew?  When average physical abilities of the work force do not meet the physical demands of the job, injuries happen. The following are the changes that creep up on us as we age:

  • Decreased muscle mass and strength (After the age of 40, various studies show that you lose between 15 to 46% of your strength)
  • Reduced bone mass (bone mass decreases up to 30% for females and 15 % for males by age 60)
  • Loss of 1 cm per decade in height after the age of 30 from thinning back discs.
  • Reduced range of motion (ROM) and flexibility
  • Reduced endurance (the older worker has 60-80% less endurance or aerobic capacity than a 20 year old)
  • Increased recovery time needed for many working tissues
  • Increased muscle response time and fatigue
  • Older people may find it harder to maintain good posture and balance

What to do?

  • Try to keep work in “neutral zone” (between knee and shoulder level, close to the body)
  • Continue or begin regular exercise program
  • Change positions regularly and stretch the upper body throughout the day
  • Allow self paced work and opportunity for breaks
  • Design and plan work that eliminates twisting and reduces work with static muscle effort (e.g. sustained positions)
  • Seek simple solutions to accommodate physical limitations (there are many resources available)
