Other Names for The Lactate Threshold - Answer Aerobic threshold, Lactate breakpoint, onset
of blood lactate accumulation (OBLA), maximal steady rate
What is the lactate threshold? - Answer -an index of the contribution of aerobic and anaerobic
energy systems to energy expenditure
-Most athletes train at or slightly above the lactate threshold (varies markedly by sport)
-The best physiological indicator of aerobic athletic performance
Why is the blood lactate threshold important? - Answer What causes the blood lactate
threshold?
Is the blood lactate threshold related to the "ventilatory threshold?" - Answer Blood lactate
threshold is the aerobic threshold and the ventilatory threshold is the anaerobic threshold, the
ventilatory threshold occurs about the same time BL begins to accumulate
Other Name for Oxygen Debt - Answer Elevated Post Exercise O2 consumption (EPOC)
What is the oxygen debt? - Answer the amount of extra oxygen required by muscle tissue
during recovery from vigorous exercise, the difference between the amount of oxygen required
after strong muscular activity and the amount required in a resting state
What causes the oxygen debt? - Answer Oxygen debt occurs when the body reaches a state of
anaerobic respiration during intense exercise. When a person engages in high levels of physical
activity, the body cannot distribute oxygen to the cells at a sufficiently rapid pace to keep up
with the oxygen demand
What does the oxygen debt have to do with the restoration of muscle CrP, ATP and glycogen? -
Answer muscle glycogen must also be restored
Measurement of energy expenditure - Answer direct calorimetry and indirect calorimetry
,What is diet-induced thermogenesis? - Answer after the ingestion of food, our metabolic rate
increases because energy is required to digest, absorb, distribute, and store nutrients
What causes fatigue? - Answer
What does the wingate test measure? - Answer peak anaerobic power, anaerobic fatigue and
total anaerobic capacity
What is the Wingate test? - Answer All out pedaling for 30 seconds at various resistance
(between 45g/kg for adults to 90g/kg for athletes (pre-draft)
When was the Wingate test developed? - Answer 70s
Anaerobic capacity tests besides Wingate test: - Answer Sprint test, FIFA interval tests, beep
tests
What is a VO2 max? - Answer A maximum rate at which an individual can consume O2 during
maximal exertion
How is VO2 max expressed? - Answer Expressed as the maximum volume of oxygen
consumed/min
Absolute measurement of VO2 max - Answer litres per min (L/min)
Relative measurement of VO2 max - Answer milliliters per kilogram per minute (ml/kg/min)
What is 1 MET? What is the measurement? - Answer metabolic equivalent = A unit used to
estimate the metabolic cost oxygen consumption) of physical activity = 3.6 ml O2/kg/min
How is VO2 Consumption assessed? - Answer By collecting expired air
Two tangible ways to assess VO2 consumption - Answer Douglass bags and metabolic cart
, Defect of VO2 max - Answer Not the best indicator of athletic performance potential
What is a Douglas bag? - Answer an inflatable bag used to collect expired air for the
determination of oxygen consumption and basal metabolic rate
What do you do during the Bruce test? - Answer 3 minutes interval with increases in speed and
incline
What is the Bruce test? - Answer Used to monitor cardiac function in exercising patients (also
called "Stress test")
Why is the Bruce test used? - Answer Used by coaches and exercise physiologist to determine
V02max in runners
How is VO2max measured? - Answer often measured by indirect calorimetry as a global index
of aerobic fitness
Blood lactate concentration - Answer an index of anaerobic metabolism, not anaerobic power
Lactic acid formed in...due to.... - Answer resting skeletal muscle due to breakdown of blood
glucose
Evenly Aerobic - Answer Lactic acid removal matches its production
Unevenly Aerobic - Answer Lactic acid production exceeds its removal capacities
Lactate dehydrogenase (LDH) function - Answer reduces pyruvate to lactate within the cytosol
Lactic Acid metabolism formula - Answer Pyruvate + NADH + H+ {LDH} Lactate + NAD+
What does an acidic environment result in? - Answer Fatigue
Does lactic acid cause fatigue? - Answer No
