Muscle Mass – Why should I know it?
According to the American College of Sports Medicine
(ACSM), lean muscle mass may decrease by almost 50%
between the ages of 20 and 90. An inactive/sedentary
lifestyle can cause loss of lean body mass while body fat
increases. It is also important to know your muscle mass
percentage during weight reduction. At rest, the body
burns approximately 110 additional calories for each
kilo of muscle gained. Benefits of gaining muscle mass
include:
• Reversing the decline in strength and bone density
• Maintenance of flexible joints
• Guide weight reduction when combined with a healthy diet
