List 8 health benefits associated with regular participation in physical activity. - ANS decrease
U
in: Resting heart rate, blood pressure, depression
increase in: stroke volume, respiratory capacity, metabolic rate
weight loss/maintenance, improved posture
LA
How can interval training improve athletic performance? - ANS increase stroke volume=
increased cardiac output
increased tidal volume and breathing ratio= efficient use of O2 in blood
increase CO2 removal due to high pulmonary ventilation= appropriate acid balance
C
List 3 physiological adaptations that occur to improve exercise performance and state how or
why improvement occurs. - ANS increase of capillaries per muscle fiber= rich supply of O2 and
nutrients
rapid removal of CO2 and waste allows maximum energy production
O
increase in glycogen & triglycoride storage in skeletal muscle
increase in mitochondrial volume and activity= increase in enzymes
D
Define ENERGY and it's food source. - ANS Energy= the ability to do work.
Food source is carbohydrates, protein, and fats.
Define ATP. - ANS High energy phosphate molecule required to provide energy for cellular
function. Produced both anaerobically and aerobically and stored in the body.
ATP-CP/ phosphagen system - ANS Simplest of 3 systems- short bursts of energy
fuel source= creatine phosphate
intensity= very high 95% of max intensity
duration= 15-20 seconds
, Uses of this system= sprinting, jumping, lifting heavy things quickly, throwing a ball, kicking
Lactic acid system - ANS anaerobic glycolytic, sustained high intensity effort lasting 1-2
minutes
fuel source= glucose- carbs breaking down into sugars
intensity= short rallies, bursts, high-moderate 85-94% of max intensity
duration= 1-2 minutes
Uses of this system= prolonged sprints, rallies in soccer, floor routine in gymnastics,
Aerobic system - ANS oxidative metabolism
fuel source= glucose, fat, or protein
A
intensity= moderate 75-85% of max intensity
duration= 3-5 minutes or more
Uses of this system= resting activities, walking, jogging, swimming,
R
AEROBIC - ANS with oxygen; requiring oxygen to be sustained
ANAEROBIC - ANS without oxygen; short bursts w/o oxygen, explosive movements
U
STEADY STATE - ANS constant submaximal exercise below lactate level so that energy
production and oxygen absorption meets requirements of imposed exercise
LA
EXCESS POST-OXYGEN CONSUMPTION (EPOC) - ANS O2 remaining elevated above
resting levels for several minutes during recovery
OXYGEN DEFICIT - ANS O2 consumption is lower than necessary to supply appropriate ATP
production required of any exercise
C
ANAEROBIC THRESHOLD - ANS The point at which the body can no longer meet its demand
for oxygen and anaerobic metabolism is accelerated
O
AEROBIC CAPACITY - ANS Ability of the body to remove O2 from the air and transfer it thru
lung and blood to working muscles
D
LACTIC ACID - ANS By-product of anaerobic metabolism of glucose.
AEROBIC QUALITIES - ANS -complete breakdown of glucose
-can utilize carbs, fats, or proteins as fuel
-long duration activity
-smaller EPOC
-submaximal work (moderate intensity)
-CO2 and H2) are end products
-uses oxygen in chemical breakdown
