Three Energy Pathways

1- Define the three energy pathways. For each pathway, identify two exercises that utilize the pathway. If you were training to run a marathon, which pathway would be the focal point of your training? What types of activities would you incorporate into your marathon training and why? How will an understanding of energy pathways help you in your future training endeavors? Pathway:

The Adenosine triphosphate / Creatine Phosphate Energy pathway: It is the energy pathway that provides anaerobic source of phosphate bond energy. The energy librated from splitting of CP rebounds ADP and Pi to form ATP.

ATP is the energy source for all human movement. The release of one phosphate molecule provides the energy for the human movement.

CP is the hi-energy

This process uses either glycogen or glucose to convert ADP back to ATP. In this case the waste product is Lactic ACID! This builds up more quickly than it can be flushed out of the muscle to the point of muscular fatigue. At this point the body must either stop or slow down until the lactic acid is removed which is then converted into Lactate which is used to produce more glucose or as an energy

blood lactate usually return to normal within an hr after activity.

Exercises utilizing this pathway:

Powerlifting: relies mainly on anaerobic energy pathway for energy boosting.

Repeat chase, catch & wrestle drill- In a restricted area (10m X 10m) 1 athlete is the chaser while the other is the evader

Working on 45s intervals- the evader tries to stay away from the chaser

When the chaser catches the evader he/she wraps them up then wrestles the ball from them

The evader makes this ball wrestle as difficult as possible

As soon as the ball is stolen it is thrown back to the evader who again tries to evade the chaser

This continues for the work period- emphasis is on high intensity in the chase/evasion and then the competition for the ball

Complete 5 X 45s work intervals with each new effort beginning on 2:15- 1:2 work:rest

2-minute recovery between blocks

Repeat with the roles changing.

3-The Oxidative Pathway:

It is a system that is aerobic, which means it uses oxygen to produce ATP. More ATP is produced through this pathway then other pathways, however it takes much longer.

It is only in this pathway where fat can be used for energy.
