5 Facts About Muscle That You May Not Have Known

Sartorius_muscleHow much do you really know about your body? The body is an amazing organism that is able to function because the heart continually pumps blood throughout the entire body, beating about 100,000 times a day and 1,000,000 times over the course of a week. Depending on the activity you’re doing, the typical heart will pump one to seven gallons of blood a minute, and as much as 2000 gallons a day. In addition to the heart, you have 650 muscle, 185 joints and 206 bones in your body (52 of those bones are in your feet) that enable you to move like an Olympic athlete (on a good day). Let’s look a bit deeper at muscle, here are five facts about muscle that you may not have known.

  • Skeletal muscle makes up about 40% of your body weight.
  • You use 200 muscles to take just one step.
  • Approximately 85% of your body heat is generated by muscle tissue.
  • Muscle can only pull (not push), contract and relax. If all of the muscles in your body could all pull in one direction, it would create a force of 25 tons!
  • The longest muscle is the Sartorius in your thigh (about 12″), the largest is the Gluteus Maximus and the smallest is in your ear, the Stapedius.
