8 health benefits associated with regular physical activity - ANSWER Lowers risk of
heart disease, reduce risk of cancers, reduce stress, anxiety and depression, increase
self esteem, lower blood pressure, increase endurance of cardiovascular system and
respiratory system.
How does interval training improve aerobic performance? - ANSWER Interval training
is used to maximize aerobic power and aerobic endurance as well as anaerobic power.
3 adaptions that occur to improve exercise performance - ANSWER Heart, Lungs and
Muscle to enhance delivery of Oxygen and speed of removal of Carbon Dioxide. Increase
in stroke volume and breathing rate. Higher amount of developed blood vessels in
muscles.
Energy and its food source - ANSWER Energy is the ability to do work. The source of
energy is the Sun.
ATP - ANSWER Adenosine Triphosphate, substance produced by the conversion
process of energy released from chemical/food sources used for muscular contractions
and exercise.
Anaerobic Pathway ATP-CP - ANSWER Energy Source: Creatin Phosphate
Intensity: Very high intensity
Duration: 15-20 seconds
Examples: Sprinting, jumping, kicking, heavy lifting
Lactic Acid System - ANSWER Energy Source: Glucose
, Intensity: Sustained high intensity
Duration: 45-90 seconds
Examples: Soccer, field hockey, basketball, lacrosse
Aerobic Pathway - ANSWER Fuel Source: Carbs, fats, proteins
Intensity: Low/Moderate
Duration: at least 5 minuets w/out fatigue
Examples: Running, Swimming, Cycling, Sleeping, Reading
Aerobic - ANSWER With Oxygen or presence of Oxygen
Anaerobic - ANSWER Requiring no Oxygen
Steady State - ANSWER After 3-4 minutes when O2 uptake has reached an adequate
level to meet O2 demand of tissues. Heart rate, cardiac output, pulmonary ventilation
have all reached constant levels.
Excess post-oxygen consumptionEPOC - ANSWER Oxygen debt- O2 uptake remaining
elevated above resting levels for several minuets during recovery.
Oxygen deficit - ANSWER Period in which O2 consumption is below what is necessary
to supply appropriate ATP production for exercise.
Anaerobic Threshold - ANSWER Point when body can no longer meet its demand for
O2 and anaerobic metabolism is accelerated.
Aerobic Capacity - ANSWER Ability of body to remove O2 from air and transfer it
through lungs and blood to working muscles.
