OBLA

    Cards (25)

    • How is blood lactate level measured in this tutorial?
      Millimolecules of blood lactate per 1000
    • What happens to blood lactate levels as exercise intensity increases?
      They gradually increase
    • What is the definition of OBLA?
      Onset of blood lactate accumulation
    • What does rapid onset of blood lactate accumulation indicate?
      Blood lactate builds up quickly during exercise
    • At what blood lactate level does rapid accumulation begin?
      4 millimolecules per thousand
    • What happens to an untrained performer when they reach 4 millimolecules per thousand?
      They begin to fatigue or slow down
    • Why do hydrogen ions associated with lactate affect exercise?
      They denature aerobic enzymes
    • How does a trained athlete's blood lactate response differ from an untrained athlete's?
      They can exercise at higher intensities before reaching 4 ml
    • What is another term for OBLA?
      Lactate threshold
    • How is OBLA related to VO2 max?
      It is a percentage of VO2 max
    • What effect does increasing VO2 max have on OBLA?
      It delays the onset of OBLA
    • What type of training can help increase tolerance to lactate?
      Aerobic training
    • What is the significance of the 4 millimolecules per thousand threshold?
      It indicates the limit of lactate tolerance
    • How does training affect an athlete's ability to tolerate lactate?
      Training can increase lactate tolerance marginally
    • What is the relationship between exercise intensity and blood lactate accumulation?
      Higher intensity leads to faster lactate accumulation
    • What does the steepening of the curve indicate in the context of blood lactate levels?
      Rapid accumulation of blood lactate
    • How does the concept of OBLA relate to fatigue during exercise?
      OBLA indicates when fatigue begins due to lactate
    • What is the main takeaway regarding trained versus untrained athletes and OBLA?
      Trained athletes can tolerate higher intensities before OBLA
    • What does the term "tolerance to lactate" refer to?
      Ability to withstand higher lactate levels
    • What is the primary focus of this tutorial?
      Understanding OBLA and its implications
    • What does the tutorial suggest about the relationship between training and OBLA?
      Training can increase the threshold for OBLA
    • What is the significance of the term "rapid" in OBLA?
      It emphasizes quick accumulation of lactate
    • What is the role of aerobic enzymes in relation to lactate?
      They are denatured by hydrogen ions from lactate
    • How does the tutorial describe the relationship between exercise and blood lactate levels?
      Exercise intensity affects blood lactate accumulation
    • What is the impact of reaching the OBLA threshold?
      It leads to fatigue and reduced exercise capacity
