Skeletal muscles attach to your bones and enable you to conduct various movements and tasks. Skeletal muscle disorders or injuries can have a significant impact on your life. Read on to learn more about skeletal muscle mass, including what it is, how it works, what conditions can influence your muscles, and how to boost your body’s muscle proportion.



Everything You Should Know About Skeletal Muscle Mass

Skeletal muscles are present all over your body and found between the bones. Skeletal muscles make up most of your muscles and account for 30 to 40 percent of your overall body weight. Each muscle fibers run the length of the muscle. Each muscle consists of thousands of fibers. Muscle fibers tighten, allowing the muscles to move bones and conduct various movements.

Skeletal muscle mass is organs of the vertebrate muscular system primarily linked to the skeleton by tendons. Tendons run the length of your body, connecting skeletal muscle tissue to bones. Skeletal muscles include:

  • shoulder muscles
  • hamstring muscles
  • abdominal muscles


Skeletal muscles account for around one-third of your total body weight, but this varies by individual. Skeletal muscle mass is 36% higher in men than in women. People who are tall or obese have more muscular mass. People lose more muscle mass as they get older.


Functions of Skeletal Muscle Mass

The skeletal muscles play an essential role in the musculoskeletal system. Functions of the skeletal muscles include:

  • supporting muscle contraction
  • supporting chewing and swallowing movements
  • expanding and contracting your chest cavity
  • maintaining body posture and balance
  • protecting joints and keeping them in place
  • allowing humans to move and perform activities


Definition of the musculoskeletal system: Musculoskeletal system refers to a set of organs, including bones, cartilage, ligaments, tendons, and connective tissues. This system supports humans’ movements by using muscular and skeletal systems.

What Can Affect Skeletal Muscles Mass?

Skeletal muscle mass can be affected by various illnesses, ranging from minor to major injuries, including life-threatening conditions such as Myopathy. Others include:

  • Muscular Dystrophies: A category of disorders characterized by the gradual loss and weakening of muscles. Muscles atrophy and weaken over time, reducing your ability to walk and perform daily activities.
  • Myasthenia gravis: An autoimmune disease in which the immune system targets the body’s own tissues. This disease interferes with nerve and muscle transmission, affecting your ability to move and probably leading to severe breathing problems.
  • Rhabdomyolysis: A rare condition caused by muscle breakdown and muscle death. This dangerous muscle damage can result from overexertion, trauma, toxic substances, or disease.
  • Sarcopenia: This condition refers to the involuntary loss of skeletal muscle mass and strength that occurs as people age.
  • Muscle strains: This condition happens when a muscle becomes overstretched. Strains usually result from exhaustion, overuse, or inappropriate use of muscles.
  • Tendonitis: Occurs when a tendon becomes inflamed or swollen due to an injury, causing joint discomfort and stiffness.


How To Increase Skeletal Muscle Mass

After understanding how skeletal muscle mass functions, it’s time to look into ways of gaining more muscle or improving muscle definition:

  • Do resistance training plus strength and conditioning exercises.
  • Follow a healthy and balanced diet to help maintain healthy bones and muscles. Your diet should include vitamin D, protein, calcium, and omega-3 Fatty Acids.
  • Maintain healthy body weight and an appropriate percentage of muscle mass.
  • Do stretching and warm-up before/ after physical activities.


To keep a healthy percentage of muscle mass, follow these normal ranges:

  • Ages 20-39: 75-89 percent for men, 63-75.5 percent for women
  • Ages 40-59: 73-86 percent for men, 62-73.5 percent for women
  • Ages 60-79: 70-84 percent for men, 60-72.5 percent for women
