Energy Production
With aerobic exercise training, an increase in this organelle is a key change that allows energy production via Krebs Cycle.
What is mitochondria?
This is the receptor for acetylcholine that is involved in heart rate modulation.
What is muscarinic receptor?
This neurotransmitter is released at the neuromuscular junction to elicit muscle contraction.
What is acetylcholine?
This is the best method for assessing Total Energy Expenditure in Free Living Environment.
What is Doubly Labeled Water
These are banned synthetic hormone (included in law 2014) that increases muscle size/strength.
What anabolic androgenic steroids?
The is the key regulating enzyme of glycolysis.
What is phosphofructokinase?
An increase these three factors will causes the oxyhemoglobin curve to shift right.
What are PCO2, temperature, and 2,3 DPG?
The undergraduates agrued two theories of fatigue.
What are peripheral (lactate) vs. central (neuro) fatigue?
This is the method you would use if you want to get a field measurement of exercise energy expenditure.
What is indirect calorimetry?
Performance is affected when dehydration is greater than this % of body mass reduction.
What is 2%?
When this shuttle is used to take NADH from cytosol into mitochondria, we get 2.5 ATP produced per NADH in ETC.
What is malate-asparate shuttle?
This physiological event will reduce afterload.
What is arteriole vasodilation?
This protein covers the binding site for myosin on actin.
What is trypomyosin?
During prolonged exercise, these two substrates are contributing about 25% each towards energy production. (BE specific)
What are blood glucose and muscle glycogen?
Exercising in heat can cause a variety of conditions - in this condition, core temperature is greater than 40 degree C.
What is exertional hyperthermia (lead to exertional heat stroke)?
This is the key regulated enzyme of Krebs cycle.
What is isocitrate dehydrogenase?
Increase in preload and thus stretch and force of contraction is a based on this law.
What is Frank Starling Law?
When this is released, myosin forms a stronger attachment to actin.
What is Pi?
This substrate has little to no contribution of energy needs (energy production) at 25% of VO2 max assessed at 30 min of Exercise.
What is muscle glycogen?
This occurs in cold weather and is characterized by swollen, edema foot, with feeling of numbness.
What is trenchfoot?
This protein can phosphorylate HSL inhibiting IMTG mobilization in skeletal muscle.
What is AMPK?
Peripheral receptors stimulus inactivate these channels which result in cell depolarization.
What are K+ channels
Calcium is released from the sacroplasmic reticulum via this channel. Note: calcium release channel does not count.
What is ryanodine receptor?
Accuracy in these two methods of body composition range to 2-4%.
What are hydrostatic weighing and ADP?
What are carbon monoxide and Oxyhemoglobin curve?
