Exercise and good nutrition are essential to maintaining a healthy muscular system, according to Healthline. Strength training can slow the loss of muscle that accompanies aging, fortify muscle and connective tissue, increase bone density, reduce the chances of injury and ease arthritic pain, according to WebMD. Studies also show that strength training improves balance, reduces the risk of falling, helps control blood glucose levels and improves sleep and mental health.
Muscle pain can signal any of a wide variety of disorders ranging from bruising to multiple sclerosis, according to Healthline. There are three types of muscles in the body: skeletal, cardiac and smooth muscle. Skeletal muscle is under voluntary control, with more than 600 skeletal muscles making up 40 percent of body weight. Cardiac muscle involves involuntary movement, and is responsible for the rhythmic pulsation that pumps blood through the body. Smooth muscle is also involuntary, and is found in the walls of hollow organs, respiratory passages and blood vessels.
Core exercises help strengthen the abdominals, back and pelvic muscles and enable the body to perform daily activities. Some foods that are needed to maintain good muscle tone include fatty fish such as salmon, which contains vitamin D; eggs for complete proteins; and olive oil containing monounsaturated fats.
