What are you studying? (Break Time)

Exercise Physiology. 10:00a.m. final.


Don't read past here. Just a copy and paste...
Resting Cardiovascular Changes Observed After Endurance Training
• Training Cardiac Hypertrophy
• (Greater vent. cavity size)
• Greater Blood Volume
• Lower [Hgb], Hct
PV increases more than RBC Vol.
• Greater Capillary Density
• Greater PNS (vagal) tone
• Lower SNS influence
• No Q change. ‘
• Lower HR
• Greater PNS/Lower SAS
• Greater SV
• Bigger cavity Size
• Longer filling time
SUBMAXIMAL ENDURANCE
• Cardiac Output during the same submaximal exercise is the same after Endurance Training.
• Increased SV
• Decreased HR
• Muscle blood flow is lower after Endurance Training.
• Increased liver/skin flow
• VO2 Not Changed
• (a-v)O2 diff is higher
MAXIMAL ENDURANCE
• Cardiac Output is Higher
o Stroke Volume is higher
• Increased Pre-Load (longer filling time, More Plasma)
• Smaller After-Load
o HR doesn’t change
• Muscle Blood flow is higher
• (a-v)o2 difference is higher
• V02Max is higher
o Increased Cardiac Output (Greater SV)
o Increased (a-v)o2 Diff
• Increased muscle blood flow, capillaries, mitochondria, and myoglobin
• The Greater VO2max with training is due to roughly equivalent increases in Q, (a-v)O2 diff [VO2max = Qmax x maximal (a-v)O2 diff]
o Trained people deliver more O2 because of Greater pumping capacity of the heart, rather than by increasing the CaO2.
• Genetics accounts for ~40% of the differences observed in VO2max.
o Effects of Endurance Training on The Heart
o Lower resting heart rate
o Lower heart rate for standardized, submaximal exercise
o Faster recovery of heart rate after standardized exercise
o Higher blood volume pumped per heart beat (stroke volume)
o Higher size of heart muscle (cardiac hypertrophy)
o Greater blood supply to heart muscle
o Greater strength of contraction of the heart
• Effects of Endurance Training on The Blood Vessels and Blood Chemistry
o Reduced resting systolic & diastolic pressures
o Reduced risk of atherosclerosis
o Serum lipids
o Lower blood triglycerides
o Lower total cholesterol
o Lower LDL cholesterol
o Higher HDL cholesterol
o Greater blood supply to muscles
o Greater blood volume
• Improved glucose tolerance
o Greater sensitivity of cells to insulin
o Lower insulin secretion in response to glucose


• Endurance Training increases Mitochondrial Power
• Endurance trained muscle has more:
o [Myoglobin]
o Size of Mitochondria
o Number of Mitochondria
o TCA Enzymes
o Enzymes for Fatty Acid Oxidation
o Enzymes of Ketone Oxidation
o Electron Transport Enzymes
o Malate Aspartate Shuttle
• The increase in mitochondrial enzymes allows muscle to breakdown Fatty Acids faster
o Allows muscle to use 02 faster
• Endurance trained muscle has less of Most Glycolytic Enzymes:
o PFK
o Phosphorylase
o Total LDH
o LDH-M
• More Heart Type LDH
• Biochemical Changes in Skeletal Muscle After Endurance Training
o Capillaries (increased capillary density*)
o Muscle [Glycogen]
o Muscle [Triglyceride]
o Decreased SympathoAdrenal Activity
o Decreased Blood [Epinephrine]
• Endurance trained people can increase their VO2 more quickly when they start exercising

Right now: working on a paper on Tokyo's Transportation Systems. Great topic, but shit, a lot of writing.

Next week:
Quantitative Methods for Geographers (Stats class)
GIS
Cartography

Got out of a final a few hours back.. picked up a six pack and chilled over at a buddy's place for a few hours and relaxed. Couldn't switch gears into another subject after the final I took.. my mind is absolutely shred to pieces.
