Metabolism During Exercise

Heat

ATP and Creatine

ATP and Creatine

• decrease in ph
• causes muscle pain/burning
• fatigue

Muscle releases Lactic Acid into liver then filters it, converts it to glucose.

• Strength and agilitys
• split seconds of power

ex: tennis serve, lefting weights, burst of speed

• endurance,
• low and moderate entensity over a long duration
• dependent more on fat

ex: long swim, hiking, jogging

• 1. what is available from the diet
• 2. the intensity and duration of avtivity
• 3. degree in which body is conditioned to perform.

will last during exercise which influences performance.

influence endurance

better performance

• - glycogen
• - fat

Faster

Not only diet but the activity

physical exertion becomes nearly impossible.

after a few hours of strenuous activity (aerobic) glycogen gets depleted.

happens to marathon runners

• - During last stages of endurance activity glucose consumed during the event goes from G1 to muscles providing needed glucose.
• - eating w/in 15 min. accelerates glycogen. high glycemic foods are better

• get glycogen stores as high as possible
• eat little carbs

• do not want to do this often can cause anhythmias
• maybe do it 2-4 times a year

it provides a lot of energy.

over 20 minutes

higher less fat will be used

allows body to adapt. and use more fat. you get more mitocondria out of this.

Substances or devices that enhance energy production, use or recovery and provide athletes with a competitive advantage.
