measurements of energy expenditure

Question 1

what is lactate sampling

Answer 1

means of testing the point at which obla occurs to monitor training and predict performance

can also be used to measure potential- a fitness test

Question 2

what sports is lactate sampling used for

Answer 2

running
rowing
swimming

Question 3

how is lactate sampling recorded

Answer 3

take a sample of blood using a pinprick device/needle

analyse the blood to see how much lactate is present (blood lactate level)

Question 4

LS- if lactate levels rise during training it is due to ………… higher levels of lactate means ….

Answer 4

anaerobic glycolysis

higher levels of lactate means higher intensity

Question 5

the higher the pace that lactate threshold occurs the

Answer 5

fitter the performer

Question 6

what is the blood lactate level at rest

Answer 6

1-2 mmol

Question 7

the lactate threshold is normally a …….. increase

Answer 7

2 mmol increase of lactate per liter of blood above resting levelss

Question 8

how does lactate sampling relate to the level of performer and what they can do

Answer 8

it will allow the performer to select relevant training zones ( eg hr or power/watts) to get the desired effect of training

Question 9

how does lactate testing allow you to monitor improvements

Answer 9

coach and performer can compare results over time and see if there is an improvement. this is indicated by achieving a lower lactate level at the same intensity

Question 10

achieving a lower lactate level at the same intensity of exercise indicates what

Answer 10

performer has an increase in peak speed/power, increased time to exhaustion improve recovery hr and higher lactate threshold.
