                The purpose of this study was to investigate the result of an eight week-modified High Intensity Circuit
Training (HICT) program on core stabilizer, quadriceps, hamstrings, deltoid muscles strength and quality of life
in obese women. The participants were twenty-two sedentary women between ages of 30 –and 40 years who
had body mass index (BMI) of 25.0 – 29.9 kg/m2. The participants were randomly divided into two groups of 11
persons which were trained group and untrained group. The trained group would be trained with the modified
High Intensity Circuit Training program for eight weeks – three days per week. The exercise time per cycle was
7.5 minutes by exercising one cycle is the first round, two cycles in the 2-3 round, three cycles in the 4-5 round,
four cycles in the 6-7 rounds. Both groups were measured by variables which were quadriceps, hamstrings,
deltoid, core stabilizer muscles and quality of life questionnaire (SF-36 Thai version) at week 0 and week 8. The
results showed that there was no significant difference between the two groups. However, the trained group
had significant increases in muscle strength of core stabilizer muscle (p<0.05) while there was no significant
difference in muscle strength of arms and legs. In addition, the trained group felt less pain on body injury and
more energetic than before training (p<0.05). In conclusion, exercising with an eight-weeks modified HICT
program in obese women could help increase the strength of the core stabilizer muscles and had the effect on
the quality of life in terms of body pain perception and feeling more energetic in the workplace. However, there
was no significant in the control group.
