One of the most common clinical mistakes is to arbitrarily assign resistance training levels to older adults, often choosing very low intensities. These low loads are often insufficient to increase muscle strength. Drs. Dale Avers and Marybeth Brown of the American Physical Therapy Association’s Section on Geriatrics published a whitepaper in the Journal of Geriatric Physical Therapy on strength training for older adults.

Both the Section on Geriatrics and the American College of Sports Medicine recommend strength training at 60% of 1 repetition maximum (RM) as the minimal intensity for strength gains. 1RM is the maximal amount of resistance an individual can move for only one repetition. Unfortunately, it’s often difficult to determine 1RM capabilities in older adults. Even using a multiple RM equation to estimate 1RM may not be accurate, since they haven’t been validated in older adults. However, using Thera-Band® resistance to quantify a multiple RM level has been validated in older adults (Manor et al.)

Using a “rating of perceived exertion” or RPE scale has been advocated to better estimate resistance exercise intensity. There are 2 popular RPE scales: the Borg scale and Omni scale.  Several studies on older adults using elastic resistance have used Borg’s RPE scale to dose intensity, and More >
