It is well known that people of all ages benefit from regular physical activity. Exercise reduces the risk of coronary heart disease, hypertension, certain kinds of cancer, type 2 diabetes, and many other chronic diseases. However, muscular strength is an important component of physical fitness with an independent role in the prevention of many chronic diseases.

More than 80% of people in the United States who are older than 65 years have 1 or more chronic medical problems, and 50% have 2 or more.  The cost of care for the elderly is at least 3 to 4 times that of younger populations and is rapidly growing, mostly because of a lack of preventive approaches and overly medicalized and fragmented care. Physical exercise is one of the few strategies able to improve muscle health in old age through multiple metabolic and gene induced adaptations. Clinicians could use nutritional supplements and exercise strategies, especially protein supplementation plus strength (resistance) training, to effectively improve the physical activity and health of all older patients. Recent evidence, shows that chronic low-grade inflammation also contributes to the loss of muscle mass, strength and functionality, referred to as sarcopenia. Sarcopenia affects both muscle protein breakdown and synthesis through several metabolic pathways. The therapeutic potential of anti-inflammatory strategies is of great interest, as these might add up to/support the anabolic effect of resistance exercise and/or protein supplementation.

The benefits of resistance (strength) training:

  • improved glycemic control and muscle strength in elderly patients with type 2 diabetes
  • resistance training with high intensity can be a strategy to treat patients with type 2 diabetes and sarcopenia associated with aging
  • its helps to restore loss of activity of the endocrine system with aging
  • there is evidence that physical exercise induces activity of the growth hormone-insulin-like growth factor-1 axis and so produces anabolic effects in skeletal muscles
  • physical exercise may increase local effects of sex steroid hormones, and this may be more important than levels of circulating sex steroids for the maintenance and function of skeletal muscles
  • in elderly women, both increased physical exercise and reduced body fat may decrease levels of circulating sex hormones
  • strong functional benefits for older adults with osteoarthritis
  • older adults with osteoarthritis benefit from a strength-training program that provides progressive overload to maintain intensity throughout an exercise program
  • strengthening exercise programs for the core and hip muscles can improve the mobility of older adults, reduce kyphotic posturing, and reduce the risk of osteoporotic vertebral fractures
  • high-intensity resistance training has been demonstrated to improve bone mineral density in lumbar and femoral bones
  • resistance exercise with focus on strengthening the back muscle extensors can be beneficial in the management of osteoporosis, especially in postmenopausal women
  • muscle quality (strength relative to muscle mass) increases with resistance training in older adults possibly for a number of reasons, including increased ability to neurally activate motor units and increased high-energy phosphate availability
  • resistance training in older adults increases power, reduces the difficulty of performing daily tasks, enhances energy expenditure and body composition, and promotes participation in spontaneous physical activity
  • current research has demonstrated that strength-training exercises have the ability to combat weakness and frailty and their debilitating consequences
