Collateral Pressure Distribution at Planter Aspect of Standing Posture of Female Sportsperson as an Indicator of Balance Mechanism

Sajjad Ahmad, Ravinder Kumar, Dhananjoy Shaw


Female sportspersons are showing good performance and their performance is improving day by day. There are negligible bio-mechanical research studies on Indian female sportspersons. The measurement of plantar pressure of foot has been accepted as a vital biomechanical parameter to evaluate posture or walking of the human. The plantar pressure measurements during standing, walking and running can demonstrate the mechanics of foot disorders and give objective measures to improve performance in sports or to track disease progression. Several studies in foot biomechanics have reported that the plantar pressure variations are useful to determine the cause of athletic performance or pathological gait. Moreover, women and men are anatomically and physiologically different in a number of ways. They differ in both shape and size. These differences could potentially mean foot pressure distribution variation in athletic as well as nonathletic men and women. Human being having collateral asymmetricity in regard to morphological volume and functional/neurological ability, females are no exceptional. Considering the above analogy, it was hypothesized that the pressure distribution of right and left foot will be different. The present study was carried out on 27 female sportspersons (age 17–25 years). They were given a standing posture test to compare between left and right collateral pressure distribution. The parameters were measured by using the portable pressure measurement system from Zebris Inc; Germany (40×30cm), supported with WinFDM-S software (Germany). The selected variables were age (years), weight (kg), height (m) and body mass index (BMI) to describe the sample and to comply the objectives of the study. Selected variables were average left fore foot force (%), average left back foot force (%), average left foot force total (%), average right fore foot force (%), average right back foot force (%) and average right foot force total (%). Collected data were computed using SPSS software for mean, standard deviation and t-test. The pressure distribution variables were found to be different between left foot (mean = 63.47) and right foot (mean=36.52). It was concluded that the collateral pressure distribution at planter aspect of standing posture of female sportspersons are uneven.
