As the age increased, the number of muscle fibers declines. People can lose more than 25% of the type 2 muscle fibers in their bodies from age 30 to age 70. By building muscle mass and strength, resistance exercise can slow down or even reverse the aging process.
Every decade after age 30, people lose 5 pounds of muscle. It helps to build muscle strength.
Some evidence is also present that resistance exercise helps lower moderately high blood pressure.
In the elderly, more strength can lead to fewer falls.
An important factor in maintaining body weight, metabolic rate can also be increased by resistance exercise.
In women, osteoporosis is common condition. In osteoporosis, fractures occur due to accelerated bone mineral loss and it can be a crippling disease. Some research on resistance exercise has shown that it can build bone even in the elderly.
