Chapter 4 Flashcards
Respiratory exchange ratio chart
Marathon RER .71 carbs zero fats 100, rest RER .8 carbs 33 fat 67
Resting metabolic rate
70% factors age body temperature stress hormones it is the minimum amount of energy required by the body to sustain basic cellular function
What is the single best test for cardio endurance
VO to Max
Epoc
Excess post exercise oxygen consumption. Payback for deficit
Lactic threshold
The point at which the blood lactate begins to accumulate above resting concentrations causes burning during set
Lactic acid
75% is her moved through oxidation for my bloodstream and is converted into energy. 25% is cleared to glycogen stored gluconeogenesis to produce for their energy
Fatigue in its causes
Lactic acid and hydrogen ions get in the way of calcium attaching to troponin
Glycogen depletion hitting a wall
2500 cal worth of glycogen and glucose and body PCR depletion and glycogen depletion
Bicarbonate
Uses to buy for acidic environment pH of celles between 6.4 at exhaustion and 7.1
Neuromuscular fatigue
Decreased release or synthesis of acetylcholine it’s needed to form ATP
Respiratory exchange ratio
Ratio between CO2 and O2 the RER value at rest is usually close to equal the higher the value of the more carbs being used 1.0 the lower the value the more fat being used .70
