. ▁Acc ur ately ▁meas uring ▁the ▁la ct ate ▁blood ▁concentration ▁involves ▁taking ▁blood ▁samples ▁( norm ally ▁a ▁pin pr ick ▁to ▁the ▁finger , ▁ear lo be ▁or ▁thumb ) ▁during ▁a ▁r amp ▁test ▁where ▁the ▁exercise ▁intensity ▁is ▁progress ively ▁increased . ▁ ▁Acc ur acy ▁of ▁blood ▁samples ▁ ▁Blood ▁samples ▁are ▁a ▁popular ▁way ▁of ▁meas uring ▁the ▁la ct ate ▁blood ▁concentration , ▁however ▁there ▁are ▁many ▁factors ▁that ▁may ▁affect ▁the ▁sample . ▁Every ▁individual ▁has ▁a ▁different ▁health ▁status , ▁thus ▁the ▁results ▁from ▁the ▁blood ▁la ct ate ▁response ▁can ▁vary ▁from ▁factors ▁prior ▁to ▁exercise ▁such ▁as ▁the ▁g ly c ogen ▁status ▁of ▁the ▁particip ant ▁and ▁ambient ▁temperature . ▁“ F ur ther more , ▁the ▁la ct ate ▁concentration ▁measured ▁may ▁vary ▁depending ▁on ▁the ▁sampling ▁site ▁swe at ▁cont am ination , ▁and ▁the ▁accuracy ▁of ▁the ▁la ct ate ▁analy ser .” ▁ ▁There ▁are ▁many ▁factors ▁that ▁may ▁give ▁this ▁test ▁a ▁false ▁reading ; ▁it ▁is ▁important ▁that ▁an ▁individual ▁takes ▁these ▁into ▁consideration , ▁to ▁receive ▁an ▁accurate ▁test . ▁ ▁L act ate ▁measurement ▁of ▁aer ob ic ▁and ▁an a er ob ic ▁th resh olds ▁▁ ▁The ▁aer ob ic ▁threshold ▁( A e T ▁or ▁Aer T ) ▁is ▁sometimes ▁defined ▁as ▁the ▁exercise ▁intensity ▁at ▁which ▁blood ▁la ct ate ▁concentr ations ▁rise ▁above ▁rest ing ▁levels . ▁ ▁Ana er ob ic ▁threshold ▁( An T )
