  • How do the muscles work in a bicep curl?

    Q: How do the muscles work in a bicep curl?

    A: The bicep, like other muscles, is primarily controlled by the cerebrum, a section of the brain located just above the brain stem and the cerebellum. The peripheral nervous system relies on the cerebrum to send signals to the bicep's short and long heads so that they function as a single muscle as the bicep contracts during the curl.

  • What happens when muscles get tired?

    Q: What happens when muscles get tired?

    A: According to Gatorade Sports Science Institute, muscles hurt when they tire due to the accumulation of lactic acid. Muscles produce energy by converting glycogen into adenosine triphosphate with the release of acid and carbon dioxide. Muscles tire quickly during heavy exercises causing a demand for more energy. When the amount of oxygen supply to exercising muscles is limited, aerobic respiration takes place, resulting in an acidic environment within muscle fibers.

  • How do muscles work together to produce movement?

    Q: How do muscles work together to produce movement?

    A: According to Boundless.com, muscles are arranged in groupings of agonist, antagonist and synergists that produce and modulate movement.
