13
Q

SO fibre characteristics (types of sport, contraction force, recovery, training ratio)

A
Good for endurance athletes
Provide energy for sub maximal aerobic work
Provide low contraction force
Individual fibres recover quickly
1:1 or 1:0.5 training:recovery ratio
14
Q

FOG fibre characteristics (type of sport, force volume, fatigue)

A

Used in 400m
Designed to give large amount of force quickly
Have capacity to resist fatigue

15
Q

FG fibre characteristics (type of sport, speed of contraction, DOMS, recovery)

A

Used in 100m
Used when maximal effort is needed quickly
Recruited in 2-10 seconds of contraction
Cause eccentric muscle fibre damage which then causes the DOMS for 24-48 hours
Takes 4-10 days to completely recover
