1: Where does the energy come from that we use for physical activity?
Energy mainly comes from the sun. The plants and animals, which we eat, prove us with nutrients we need for energy.
2: Define homeostasis?
Maintenance of a constant internal temperature in the body
3: What is metabolism!
Biochemical processes within a living organism that sustain life
4: List and define the two-phase of metabolism.
Phase1: Catabolism (break-down)
Phase2: Anabolism (Build-up)
5: What is BMR and how does it relate to a humans metabolic set point?
The lowest amount of energy required to maintain the body’s life function while in a resting state. This is Usually expressed in calories per hour per square meter of the surface of the body.
6: How do a kilocalorie and a calorie relate?
There are 1000 calories in a kilocalorie
7: Define the thermic effect?
The heat liberated from food as a measure of its energy content.
8: Refer to the chart below:
9: Give 5 metabolic adaptations to endurance training.
increased muscle glycogen storage capacity
increased muscle mitochondrial density
increased resting adenosine triphosphate(ATP) content in muscles
increased resting Creatine phosphate(CP) content in muscles
increased resting creatine content in muscles
10: What are the anaerobic training adaptations.
increased size and number of fast-twitch muscle fibers
increased tolerance to higher levels of blood lactate
increases in enzymes that are involved in the anaerobic stage of glucose breakdown (known as glycolysis)
increased resting levels of ATP CP creatine, and glycogen content in muscles.
increased levels of growth hormone and testosterone after short bouts (45 to 75 min) of high-intensity weight training
11: what is “ATP” and discuss the 3 energy pathways to produce it.
a compound know as Adenosine Triphosphate whose breakdown leads to energy release used for muscle contraction
