Effects of differencing heel heights on the lower limb biomechanics and energy profiles of young thai females during constant speed walking
Abstract:
The purpose of this study was to investigate the wearing of shoes with
different heel height on ground reaction force, peak torque of hamstring and
quadriceps and energy profile in young Thai females. The average aged was 18-22
years, weight about 47.59-53.91 kg., height about 160.23-160.53 cm. and BMI from
18.33-21.20 kg/m2 .
Results revealed the deviation of the three component of ground reaction
force (Fx, Fy and Fz). Whereas Fz1, Fz3, Fy2, Fx1 increased, Fz2, Fy1, Fy3 decreased,
depending on the height of heel (heel height 7.62, 6.35, 5.08 and 3.81 cm., but there
was no significant difference in ground reaction force between each heel height and
bare feet. 30 minutes walking with high-heel shoes affected on the strength of
hamstring and quadriceps muscles, in which the peak torques of hamstring and
quadriceps were decreased, but there was no significant difference between any heel
height and bare feet walking. There was an increase in heart rate, oxygen
consumption, carbon dioxide output and minute ventilation during walking with highheel
shoes. The increasing of energy profiles depends on the height of heel which were
increased significantly higher during standing position. There were no significant
difference between bare feet and high-heel shoes. The increasing of ground reaction
force may affect the joint reaction force and may lead to degenerative joint change
