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.
What is muscle fatigue?
A measurement of the electrical activity in a muscle
What is an EMG (electromyogram)?
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.
What is glycogen?
Ca2+ ions bind to this regulatory protein
What is troponin?
This artery carries blood to the brain, face, and head.
What are the carotid arteries?
Elite sprinters and marathon runners differ in the relative proportions of these types of muscle fibers
The parasympathetic nervous system is involved in this overall systemic response.
What is "Rest and Digest"?
Smooth muscle
These are the first two materials used for energy in muscle contraction.
What are stored ATP and creatine phosphate?
These are the three main system that maintain a supply of ATP during exercise, depending on the duration and intensity of the activity.
What is ATP/Creatine (Phosphagen System), Anaerobic (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).
