ALL SYSTEMS GO AGAIN!

ALL SYSTEMS GO AGAIN!

Diagrams, live action, and clear narration work together to explain the energy systems that run human muscles. First, diagrams show muscle fiber structures (including slow- and fast-twitch fibers) and how they work, and then the program discusses the body's three energy systems and their interplay: the anaerobic systems based on ATP-PC and lactic acid as well as the aerobic glycolysis system based on oxygenated blood. Local and central fatigue and recovery are also discussed, and "warm-down" activity is recommended. Grades 7–12. Color. 30 minutes. VEA (Video Education America). ©2006.
