Recent study in BMC Musculoskeletal Disorders shows that muscle strength of the back extensors declines with age, and accelerates to an approximate 50% decline the third to sixth decade of life.
The result: “Poor physical performance; increased risk of falls, fractures and disability; increased mortality and poor quality of life; fear induced inactivity are associated with a decrease in muscle strength in older adults”
StrongPosture® implication: The more time dedicated to balanced, stronger posture, the lesser likelihood of back extensor decline and loss of muscular and postural strength.
