Path of Least Resistance
This principle of resistance training states that training must occur at higher intensities than one is accustomed to.
What is progressive overload?
The body is able to store the most amount of energy in this macronutrient
What is fat (adipose tissue)?
This practice involves measuring the amount of O2 and CO2 exchanged at the lungs
What is Indirect Calorimetry?
Alterations in the CNS that cannot be explained by muscular dysfunction are described as this
What is central fatigue?
This pathway would be the predominant energy source during 2 reps at 90% of 1RM
What is the creatine phosphate (PCr) pathway?
This principle of resistance training is the reason why a sprinter's performance would not benefit from only exercising upper body.
What is specificity?
This product of glycolysis can be used anaerobically or aerobically
What is pyruvate?
This is the energy required at the onset of exercise that cannot be supplied by aerobic metabolism
What is oxygen deficit?
Decreasing ACh release from the NMJ is a sign of this
What is peripheral fatigue?
This is the predominant energy system you would use to walk from the entrance of Dale Hall, up the stairs, and to the classroom (about 45secs to 1min)
What is glycolysis?
Increases in cross-sectional area (CSA) from resistance training occur after this amount of time.
What is 8 weeks?
This enzyme attaches a Pi to ADP in the Electron Transport Chain (ETC) to form ATP
What is ATP synthase?
An RER of 0.72 would indicate that an athlete is predominantly using this energy source for energy
What is fat?
H+ ions that are responsible for fatigue come from this product of metabolism
What is lactic acid?
This is the most likely reason your physically inactive friend saw considerable strength gains after 2 weeks of resistance training
What are neural adaptations?
IGF-1 can be released from the liver or the muscle, but mechano-growth factor (MGF) is only released from this location.
What is the muscle?
During high intensity exercise more H+ is produced, limiting the activity of this enzyme
What is Phosphofructokinase (PFK)?
VO2 Max is the single best indictor of this
What is aerobic fitness?
What is muscle glycogen?
Peripheral fatigue caused by H+ inhibiting myosin ATPase activity would hinder this process
What is cross-bridge cycling?
Loading and stretching of the muscle activates the anabolic hormones IGF-1 and GH who in turn stimulate muscle growth through this pathway
What is mTOR?
This molecule stimulates activity in almost all of the rate-limiting enzymes
What is ADP?
This is the normal range of VO2Max for active, young women
What is 38-42 mL/kg/min?
Increasing levels of H+ ions would inhibit Ca2+ release from the SR, hindering this process of muscle contraction.
What is Excitation-Contraction Coupling (ECC)
Criteria for reaching VO2 Max includes reaching an RPE (19-20), 90-95% Predicted HR Max, 90% of Predicted VO2, RER > 1.1, and these two things
What are VO2 plateau and 8mmol (mM) of blood lactate?
