  Objectives: This paper introduces a new method for evaluating fitness and
determining effective exercises for reducing abdominal obesity in Korean adults
using the new kind of waist-to-height ratio (WHT2R). Materials and Methods: The
body mass index (BMI), body shape index (ABSI), and two other waist-to-height
ratios (WHT.5R, WHTR) were considered as possible contenders for the WHT2R. The
correlation coefficients were calculated by correlation analyses between the
indices and four fitness tests for comparison. The LMV (lump mean value) and
FSPW (fitness sensitivity percentage to WHT2R) were introduced to find the
association between fitness and abdominal obesity using a linear regression
method and to use as an indicator for the effective control of abdominal
obesity. Results: The WHT2R is more suitable for assessing fitness than the
other indices and can be controlled effectively by decreasing the 10-m shuttle
run score for both males and females. Conclusions: The WHT2R can be used as a
possible contender for evaluating fitness and is an effective indicator for the
reduction of abdominal obesity. The LMV and FSPW can be used to establish
personal exercise aims.
