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?
This product of glycolysis can be used anaerobically or aerobically
What is pyruvate?
This practice involves measuring the amount of O2 and CO2 exchanged at the lungs
What is Indirect Calorimetry?
This is the definition of fatigue.
What is the failure to maintain expected or required force?
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?
Glucose derived from muscle glycogen skips this enzyme in glycolysis.
What is hexokinase?
This is the energy required at the onset of exercise that cannot be supplied by aerobic metabolism
What is oxygen deficit?
This is the inability to develop an adequate amount of initial force.
What is weakness?
This is the predominant energy system you would use to sustain exercise lasting beyond 5 minutes.
What are Krebs/ETC?
Increases in cross-sectional area (CSA) from resistance training occur after this amount of time.
What is 8 weeks?
This molecule is responsible for the conversion of pyruvic acid to lactic acid.
What is NADH?
An RER of 0.72 would indicate that an athlete is predominantly using this energy source for energy
What is fat?
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, inhibiting the activity of this enzyme
What is Phosphofructokinase (PFK)?
VO2 Max is the single best indictor of this
What is aerobic fitness?
The build-up of hydrogen ions (H+) can directly impair the ECC, inhibit PFK, and inhibit the activity of this enzyme involved in cross-bridge cycling.
What is Myosin ATPase?
What are carbohydrates?
Loading and stretching of the muscle activate IGF-1, and GH, which 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?
These two factors are responsible for oxygen deficit.
What are 1) lag in oxygen delivery and 2) lag in activation of oxidative enzymes?
What is Creatine Phosphate (PCr)?
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?
