THE SPECIALIST INTERVIEW
Test 1 – Chester Treadmill Test ( CTT ).
CTT Performance ( Sykes 2007 ) is a 12-minute graded , treadmill walk test designed to assess whether or not the subject can achieve the minimum recommended standard for aerobic capacity , namely 42mlsO2 / kg / min .
Test Protocol :
a . Following a gentle loosening and limbering , the subject is then asked to walk on the treadmill at 0 % for a 2-minute warm-up , the speed being gradually increased to 6.2km / hr , when the test is commenced .
b . Level 1 : 0-2 minutes at 0 % gradient . At the end of the level , check that RPE ( see chart ) is less than 18 and if so , continue to Level 2 , increasing the gradient to 3 %.
c . Level 2 : 2-4 minutes at 3 %. At the end of the level , check that RPE is less than 18 and if so , continue to Level 3 , increasing the gradient to 6 %.
d . Level 3 : 4-6 minutes at 6 %. At the end of the level , check that RPE is less than 18 and if so , continue to Level 4 , increasing the gradient to 9 %.
e . Level 4 : 6-8 minutes at 9 %. At the end of the level , check that RPE is less than 18 and if so , continue to Level 5 , increasing the gradient to 12 %.
f . Level 5 : 8-10 minutes at 12 %. At the end of the level , check that RPE is less than 18 and if so , continue to Level 6 , increasing the gradient to 15 %
g . Level 6 : 10-12 minutes at 15 %. At the end of the level , check that RPE is less than 18 . End of test .
After 12 minutes , the subject will have reached the required fitness standard of 42mlsO2 / kg / min ( Table 1 ).
