Q

What was take home message number 1 from the lecture? (ha ha guess this one you prick)

A

All measurement tools have limitations. Try to use more than one where possible

17
Q

What is the sweet spot of acute to chronic workload ratio?

A

0.8-1.3:1

18
Q

What is the dangerous area of acute to chronic workload ratio?

A

1.5+ : 1

19
Q

What is acute workload?

A

Your workload in the last week

20
Q

What is chronic workload?

A

your workload in the last 4 weeks

21
Q

What is take home message 2 of this lecture? (gotcha again you fucker)

A

Collect data to answer a problem, dont use it to find them. Make sure you can interpret that data

22
Q

What did Quarrie et al 2013 find about the distances covered in club vs internatinal rugby?

A

Similar distances covered but international rugby run at higher speeds

23
Q

What evidence exists to suggest that rugby players exhibit fatigue over the duration of the game?

A
  • Lacome et al 2013: Decreased acceleration in second half, especially back rows
  • Roberts et al 2008, players cover greater distance in first 10 minutes compared to between minute 50-60.
24
Q

What evidence exists to refute that rugby players exhibit fatigue over the duration of the game?

A
  • Roberts et al 2008: No difference in high intensity activity across game periods
  • Duthie et al 2005: Moement patterns similar between halves
  • Lacome et al 2013: No significant decrease in physical performance between halves
25
Q

What proportion of football activity is ‘high intensity’? Reference pleaaasse

A

Carling et al 2011: Between 5 and 9 percent depending on position

26
Q

Which sport covers more distance in a game, football or rugby? How much distance is that on average?

A

10-12km. Football

27
Q

Which position covers the greatest difference in Football?

A

Midfielders would, in theory.

28
Q

What does Mohr et al 2003 find about top class vs moderate class football players and playing intensity?

A

-Top level players covered 5% more distance. More sprinting, more high intensity running, more moderate intensity running, less jogging.

29
Q

What did Di Salvo et al find about the differences in championship vs premiership football?

A

Small but significantly more distance covered in championship

30
Q

What did Carling 2008 find about differences in distance covered between halves in football?

A

3.5% less distance covered in second half
