What products from the immediate energy sources stimulate the need for (more ATP)glycolysis etc.
AMP, ADP+P (inorganic phosphate)
When are the immediate energy sources predominantly used?
Sprint, high intensity
List the basic equations of the 3 immediate energy sources. (See handouts),
ATP-ATP + H2O <ATPase> ADP+ P (Inorganic phosphate) +Energy)
CP- PC + ADP<CRKinase>ATP + Cr
ADP- ADP+ADP <Adenylatte Kinase> ATP + AMP
What products from the immediate energy sources stimulate the need for glycolysis?
AMP, ADP+P
What are the pros and cons of measuring maximal lactate steady state (MLSS) vs. lactate threshold (LT)?
MLSS- intensity at which LA levels off.-numerous visits
vs.LT- Sharp rise point-One shot
What is the relationship between exercise intensity and lactate production?
More intensity, more lactate---direct relation
How does training influence lactate production, clearance, and overall concentration?
Much better clearance
What influence does the accumulated hydrogen ion (H+)have on performance?Specifically, what influence does it have on the rate limiting step of glycolysis?
Slows PFK action Allo effects H-
If lactate is converted back into pyruvate and NADH, where will the NADH go?
ETC. Lactate goes to blood then LIVER
How does creatine supplementation affect performance?
Helps immediate energy source, fast twitch stuff, raises resting CP stores
Define “energy systems” and (list the three).
Immediate,
glycolysis +phosporalization, B Oxidation
Of the 3 main energy systems, which has the greatest potential amount of ATP supply?
Beta Oxidation
Of the 3 main energy systems, which has the greatest rate of ATP supply?
Fast glycolysis (Lactate)
