Skeletal muscle systems 2

Question 1

what is work: releif ratio

Answer 1

volume of relief in relation to volume of work performed

Question 2

When are slow oxidative fibres used
-explain force given out

Answer 2

-sub-maximal aerobic work
-contract quickly- give overall low force of contraction
-individual fibres recover quickly

Question 3

Application for training and recovery using slow oxidative fibres

Answer 3

very low work: relief ration- 1:1, 1:0.5
e.g 3 mins moderate intensity- 90s break

training can be performed on daily basis

-advised between heavy weight training sessions -> ^ blood flow, enhacnes healing process

Question 4

Application for training & recovery for fast oxidative glycoltyic fibres

Answer 4

-produce large amount of force quickly
-resist fatigue

-used in high-intensity activities, lasting few minutes (800m)

Question 5

When are fast glycolytic fibres used

Answer 5

-recruited in last 2-10 secs of contraction, when maximal efforts are needed

-accompanied by eccentric muscle fibre damage -> causes DOMS -> 24-48hrs after exercise

Question 6

Application for training & recovery for fast glycolytic fibres

Answer 6

maximal weight training- v high work-to-relief ratios

-1:3+ work: relief ratio, 3-5 mins oc rest between sets of 2-6

-once fast glycolytic muscles been used to exhaustion- take 4-10days to recover
