LEWIS: Measuring The Intensity Of Training Flashcards
Lactate sampling involves
Taking a minute sample of the performer’s blood
2 methods:
Lactate sampling
Respiratory exchange ratio (RER)
LS: the higher the reading of lactate in the blood, the higher the
Intensity of the workout being taken
LS: through experience and knowledge a coach will know how hard a performer is
Working
Lactate threshold is linked to VO2 Max - specifically the higher the percentage of VO2 max or the higher the pace at which the lactate threshold occurs the
Fitter the athlete
Lactate sampling can also be used to
Monitor training and predict performance as well as measuring potential
LS: allows the performer to personalise training zones in order to get the
Desired training effect
LS: regular lactate testing provides a comparison from which the coach and performer can see whether
Improvement has occurred
Lactate threshold is usually taken to be a
2mmol increase in lactate above resting levels.
Lactate threshold is sometimes referred to as OBLA, but OBLA is taken to be a level of
4mmol of lactate per litre of blood
LS not easily used for games players. The test requires the performer to be relatively stationary. LS tends to be used on those who work on rowing machines or stationary bicycles. these are known as
ergometers (machines designed to measure workload)
RER is the ratio of
Carbon dioxide released to oxygen used by the body
RER can be used to estimate the relative contributions of
Fat and carbohydrate to the provision of energy for ATP resynthesis
RER works as an indicator of fat and carbohydrate breakdown because fat and carbs differ in terms of
Amount of oxygen used and carbon dioxide produced during oxidation
RER fat = major fuel, the amount of oxygen being consumed will tend to be a big number which will make the volume of oxygen consumed (VCO2/VO2) and hence RER a
Small number
