What is the most appriate rest period for some1 training the LA system

[coolrunnings]

They are doing 4 X 200m sprints at 90%

A- 10-30
B- 30-60 sec
c- 70-100sec
d- 100-120sec?

Questions 5 2010 INSIGHT

[lexitu]

C sounds right.

If one sprint is about 25 seconds, then 75 seconds rest will give a W:R of 1:3.

But this question sucks, we don't know enough about the athlete. What if they can sprint 200m in 19 seconds? Then you could perhaps argue 30-60 seconds as the best range.

+1.

ye its pretty shit i reckon i would have put c. Also i have another question. What is the relationship between VO2 and HR for an elite endurance runner?

It askes which line best represents the athele and has graph with y axis vo2 and x axis hr should it be a steep line of relativly flat?

Couldnt you argue B also? Since you would be training the body to get used to LA in the muscles thus increasing the buffer of the muscles so they can tolerate more lactate?

Id say as Heart Rate rises V02 rises as this will allow a higher consumption of oxygen to be had.

[coolrunnings]

ye but if you say B it could it is more  likely to become aerobic . LA training requires a WR of 1:3

[lexitu]

It's a linear relationship - should be something like a diagonal line.

[ohmyjosh]

Awgh I hope theres no ambiguous questions like these tomorrow.

[coolrunnings]

postive linear and the steepest?? there a few lines but different gradient

[lexitu]

Lmao, yes positive, linear, and not too steep but not too slight a gradient.

Just out of interest how would it make it more aerobic?
Because in the 2010 ACHPER exam it has the rest rate for ATP-PC at 70 seconds, thus it would be 30 seconds rest for LA?
Mind you the sprint distance is 50m so about 7 seconds max.


Edit: Just realised it is 200m sprints so about 30 seconds so I guess that is correct then. I stand corrected.
So B is more aerobic since you are training the body to get used to LA?
And D would be ATP-PC since you are training the body to get used to replacing PC at a faster rate?

[coolrunnings]

So your saying:

Rest time - 70 sec

Work time - 7 sec


This is a work rest ratio of 1:10 Making atp-pc

usually 1;4 AND above is considered ATP-PC

Hope this make sense

Yes i just read your edit: that is correct

[coolrunnings]

Cheers lex

Generally 1:1 aerobic, 1:3 LA, 1:5 ATP-PC
