You just answer the questions. For detail, see additonal materials

Questions.

1.Ona single “line graph”, graph your “feeling of physiological comfort” following both the active recovery and passive recovery exercise sets. (2 pts)

2.Explain why the active recovery protocol allows for improved lactate removal and better overall recovery from intense exercise. (2 pts)

3.Describe what is meant by OBLA or Lactate Threshold and discuss several reasons why blood lactate begins to rise rapidly during increasingly intense exercise. (2 pts)

4.Graph (X-Y graph) the lactate production curves that were created for the OBLA experiment. Identify if there is a distinguishable threshold or point of OBLA. (2 pts)

5.What are the possible fates of blood lactate during the exercise recovery period? (2 pts)
