Presentation Transcript

  1. Energy System Development PETH42

  2. Observe People in the Cardio Room • Leisure Jog on the treadmill • Reading the paper while on bike • Watching news on eliptical trainer • Are we working hard enough? • Are we challenging the body? • How far vs. how fast? Quantity vs. Quality

  3. Purpose of ESD • Burn calories • Improve function of heart and lungs • Build endurance • Challenge body so that it can adapt “Progressive Overload”

  4. We’re Forgetful as Adults • Who was picked 1st in grade school • Speed & power =increased muscles and leaner body • Burn calories, increase flexibility, improve nervous system • Ever seen a fat sprinter?

  5. Verstegen Questions Methods • Keeping HR in “fat burning” zone • Training: plow horse or thoroughbred • What do you think?

  6. The 3 Energy Systems • 1. Anaerobic Glycolysis • 2. Phosphagen system • 3. Aerobic system • All systems are active, but participate more according to intensity of activity

  7. Anaerobic Glycolysis • High intensity up to 3-minutes • Handle high acid concentrations • Fiber types? • Active recovery • Work/Rest ratio 1:2

  8. Phosphagen System • High level work up to 12 seconds • Fuel in muscles used • ATP-CP • Inactive recovery • Hypertrophy of type II • Work/rest 1:3, 1:6

  9. Aerobic System • Work beyond 3 minutes • Requires oxygen to make energy • Primary fuel at rest • Work/Rest Ratio 1:1 • Marathons, distance swimming, Ultras

  10. Can you Guess the Primary Energy System? • Intensity? • Duration? • Think Fiber Types • Explosive or paced

  11. Guess this Energy system • Name the primary energy system for baseball • During active times, which are few and far between.

  12. Soccer? • There’s a lot of jogging or paced running • But, there’s also sprinting • What’s the fuel source

  13. Football? • There’s a lot of standing around between each 5-7 second play • But, the movements are explosive

  14. Basketball? • Name the energy system based on what you’ve learned from the previous slides

  15. Effect of Event Duration on Primary Energy System Used Phosphagen System 0 - 12 sec, very intense, Anaerobic Anaerobic Glycolysis 30sec - 3min, heavy, Anaerobic Aerobic System > 3 min, light, Aerobic
