The inability of muscle to maintain its strength of contraction of tension; may be related to insufficient oxygen, depletion of glycogen, and/or lactic acid buildup.
Muscle fatigue.
An organic acid present in blood and muscle tissue as a product of the anaerobic metabolism of glucose and glycogen.
Lactic Acid
Ankle-brachial index (ABI). It compares the blood pressure in your ankle with the blood pressure in your arm. Uses Ultrasound machine.
A highly branched polymer of glucose containing thousands of subunits; functions as a compact store of glucose molecules in liver and muscle fibers.
Glycogen
Permitting the exchange of nutrients and gases between the blood and tissue cells is the primary function of these.
Capillaries
This artery carries blood to the brain, face, and head.
What are the carotid arteries?
A technique for temporarily improving athletic performance in which oxygen-carrying red blood cells previously withdrawn from an athlete are injected back just before an event.
Blood Pooling
Arteries carry oxygenated blood, and veins carry deoxygenated blood, with these two exceptions.
Except for the Pulmonary Vein and Pulmonary Artery.
BONUS: What is a better characterization of arteries and veins than whether they are oxygenated?
Smooth muscle
This hormone stimulates red blood cell production.
Erythropoietin (produced by the kidney)
These are the three main system that maintain a supply of ATP during exercise, depending on the duration and intensity of the activity.
Phosphagen System, Glycogen-Lactic Acid System, and Aerobic Respiration. Phosphagen System uses creatine phosphate to make energy; for maximum effort and short duration (sprint). Glycogen-Lactic Acid System uses anaerobic espiration to turn glycogen into glucose and ATP; for slower but longer lasting (swimming). Aerobic Respiration uses all remaining glucose, then burns fat reserves, then breaks down proteins; slow but extremely long lasting (marathon).
