5. Anatomy and physiology (skeletal, muscular, nervous, circulatory, and respiratory systems)
The skeletal system provides structure, shape, and movement, and also protects vital organs. Long bones such as the femur act as levers, while joints allow specific ranges of motion. Understanding how the skeleton functions helps teachers design age-appropriate activities. For example, growth plates in children’s bones are vulnerable, so heavy resistance training for young children should be carefully monitored.
The muscular system works with the skeleton to generate movement. Skeletal muscles can be trained for strength, endurance, or power depending on fiber type recruitment. For instance, plyometric exercises target fast-twitch fibers, while continuous running conditions slow-twitch fibers. Muscle balance is important—teaching students to strengthen both quadriceps and hamstrings reduces knee injury risk.
