*Location: Sarcoplasm
* Primary Energy Source: Stored ATP and PC
* Byproducts: none
* Energy Yield: 1 ATP
* Duration of Activity: 8-12sec
* Sporting Events: 100m sprint, high jump
* Advantages: High energy in short time
* Limiting Factors: concentration of stores
* Recovery: 2-3mins (30s half recovery)
Anaerobic lactic system
a.k.a (Anaerobic glycolysis)
* Location
* Primary Energy Source:
* Byproducts:
* Energy Yield:
* Duration of Activity:
* Sporting Events:
* Advantages:
* Limiting Factors:
* Recovery:
Location: Sarcoplasm
Primary energy source: stored glucose and glycogen
Byproducts: Lactic acid
Energy yield: 2 ATP (glucose)
Duration of activity: 20s-3m
sporting events: 200-400m sprint, 50m sprin
Advantages: fairly quick delivery of energy
Limiting factors: concentration of stored glycogen and lactic acid buildup
Recovery: 2hrs
Aerobic system
a.k.a oxidative system
* Location
* Primary Energy Source:
* Byproducts
* Energy Yield
* Duration of Activity:
* Sporting Events:
* Advantages:
* Limiting Factors:
location: Mitochondria
Primary energy source: Glycogen (CHO), glucose (CHO), fats
ByProducts: H20 and CO2
Energy yield: 36 ATP (glucose) 460 ATP (TG/fat)
Duration of activty: > 3 mins.
sporting events: Walking, jogging, swimming, walking up stairs
Advantages: Large amount of energy over a
long period of time, removal of lactic acid
Limiting factors: Lung function, max. blood flow, oxygen availability, excess. energy demands
rate of accumulation of lactic acid can be decreased by:
- reducing the rate of lactate production
- increasing effectiveness of aerobic oxidative system - Increasing the lactate elimination
Aerobic Power or VO2 max evaluated by:
(ml/min/kg) maximal volume of oxygen that can be consumed per kilogram of mass in a given time.
Absolute vs. Relative VO2 max
Absolute = (L/min)
Relative = (ml/min/kg)
What are the primary roles of the cardiovascular system?
- to transport oxygen from the lungs to the
tissues - to transport CO2 from the tissues to
the lungs - to transport nutrients from the digestive
system to other areas in the body - to transport waste products from sites of
production to sites of excretion.

define Diastole and systole
Diastole: ventricles relaxing & filling with
blood
Systole: ventricles contracting, push blood
through
All arteries carry oxygenated blood, except ___________. All veins carry deoxygenated blood except ___________.
Pulmonary artery and pulmonary vein.
Plasma carries approx __% blood, comprised mainly of water __%.
55% blood, 90% water
identify the components of the respiratory system
-Diaphragm/ribs
-pharynx/trachea
-bronchioles/lungs
describe the physiology characteristics of the respiratory system
Summarize the function of the RS in
maintaining optimal health and performance
Discuss the physical activity demands of, and training effects on the cardiovascular and respiratory system collectively.
