what is the lactate threshold for an untrained person
between 50%-60% of VO2 max
what is the lactate threshold for an trained person
between 70%-80% of VO2 max
what is the lactate threshold for people with COX deficiency
between 25%-30% of VO2 max
If you increase the workload for a person with PFK deficiency, do you even see a lactate threshold?(refer to page 31)
no you don’t
because they don’t produce lactate, or very little lactate production
what does a higher lactate threshold mean
better aerobic system
what does a lower lactate threshold mean
worse aerobic system
what 3 pathways does free ADP drive
ATP phosphocreatine system
glycolysis
mitochondrial respiration
how does endurance training affect mitochondrial enzyme content (refer to page 32)
Increased Mitochondrial Density: Endurance training stimulates the production of more mitochondria within muscle cells. This increase in mitochondrial density allows for greater aerobic energy production.
review page 33
is there a difference in submaximal VO2 values between untrained and trained individuals
no
only difference in VO2 max
