Question 1

what is VO2 max?

Answer 1

VO2 max can be defined as:

“The highest rate of oxygen consumption attainable during maximal or exhaustive exercise”

Theres Relative and Absolute: Relative take body weight into account, absolute doesnt

Question 2

Steady State

Answer 2

The aerobic steady state is reached once there is a balance between the amount of Oxygen needed for activity and the amount of energy being supplied aerobically by the body

Question 3

LIP

Answer 3

Lactate Inflection Point = The LIP of an individual represents the maximal intensity at which blood lactate is in steady state. The sudden increase occurs when the rate of lactate entry exceeds the rate of lactate removal.

Question 4

Muscle fibre types

Answer 4

slow twitch = slow twitch are for endurance activities

fast twitch = high intensity and short duration activities

Question 5

muscle fibre characteristics

Answer 5

slow twitch = colour = red
speed of action = slow
resistance to fatigue = high
aerobic or anaerobic = aerobic
force production = low
storage fuel = triglycerides
glycolytic capacity = low
fibre diameter = small

fast twitch II = colour = pink
speed of action = fast
resistance to fatigue = moderate/ high
aerobic or anaerobic = both
force production = intermediate
storage fuel = CP, glycogen
glycolytic capacity = high
fibre diameter = intermediate

fast twitch IIb = colour = white
speed of action = fast
resistance to fatigue = low
aerobic or anaerobic = anaerobic
force production = high
storage fuel = CP, glycogen
glycolytic capacity = high
fibre diameter = large
