Lesson 3 Flashcards
It is a branch of biochemistry that focuses on how cells transform energy, often by producing, storing or consuming ATP.
Bioenergetics
It is the study of how energy is being used and distributed throughout the body.
Bioenergetics
3 energy systems of the body
- Immediate/ Explosive Energy System
- Non-oxidative Energy System
- Oxidative Energy System
Also known as Adenosine Triphosphate Phosphocreatine Energy System.
IMMEDIATE/EXPLOSIVE ENERGY SYSTEM
Supplies energy to short duration but high intensity movements.
IMMEDIATE/EXPLOSIVE ENERGY SYSTEM
Also known as Glycolytic Energy System
NON-OXYDATIVE ENERGY SYSTEM
Supplies energy to movements that are moderate in intensity.
⮚ It last longer than the Explosive Energy System
NON-OXYDATIVE ENERGY SYSTEM
Also known as Aerobic Energy System.
OXYDATIVE ENERGY SYSTEM
⮚ Supplies energy to movements that are low in intensity.
⮚ Unlimited, as long as there are nutrients in the body.
OXYDATIVE ENERGY SYSTEM
Is the intake of food, considered in relation to the body’s dietary need. (WHO)
Nutrition

Good Nutrition
Good Nutrition
Should take the characteristics of nutrition in consideration
- Eating in moderation
- Eating in variation
- Eating in a well-balanced diet
substances the body must get from food because it cannot manufacture them at all or fast enough to meet its needs.
