AB  - BACKGROUND: To investigate more practical handling of Borg's ratings of perceived 
      exertion (RPE) and category-ratio scale of RPE (CR-10), we evaluated 
      interrelationships between RPE, CR-10, and blood lactate concentrations (bLa) 
      during incremental treadmill running tests for young females with different 
      aerobic fitness levels. METHODS: Oxygen consumption, heart rate, bLa, RPE, and 
      CR-10 were measured from distance runners (DR; n = 15), race walkers (RW; n = 6), 
      and untrained females (UT; n = 11). These variables corresponding to the lactate 
      threshold (LT) and onset of blood lactate accumulation (OBLA) were compared among 
      these groups. RESULTS: The UT had significantly lower RPE at LT than DR and RW, 
      although the CR-10 at LT was not significantly different among these groups. The 
      CR-10 at OBLA was significantly lower for the UT than DR. The relationship 
      between bLa and CR-10 was approximated well by two linear regression lines in all 
      groups. The bLa at the intersection only for the RW was significantly lower than 
      that at LT, however, such intersections were observed at CR-10 = 3.1 to 3.2 
      without significant group differences. The CR-10 scores at LT and intersections 
      were not significantly different in each group. CONCLUSION: These results 
      suggested that an intersection between CR-10 and bLa was observed at the CR-10 
      score around three points of first half regardless of the aerobic fitness levels 
      in young females, and such CR-10 scores would be associated with LT.
