Energy System Development

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
Were 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 12

8
Phosphagen System

• High level work up to 12 seconds
• Fuel in muscles used
• ATP-CP
• Inactive recovery
• Hypertrophy of type II
• Work/rest 13, 16

9
Aerobic System

• Work beyond 3 minutes
• Requires oxygen to make energy
• Primary fuel at rest
• Work/Rest Ratio 11
• 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?

• Theres a lot of jogging or paced running
• But, theres also sprinting
• Whats the fuel source

13
Football?

• Theres 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 youve
  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
• gt 3 min, light, Aerobic
