Objective: To investigate the possible relationship between the anthropometric data, the foot types, sex and the dynamic plantar pressure of normally developed teenagers.
Method: The height, weight, body mass index and dynamic plantar pressure were measured from 98 teenagers. Foot types were classified to high arch, normal and flat foot groups depending on the value derived by dividing the minimal length of mid foot area by the maximal length of the rear foot area.
Results: The area with the highest plantar pressure was the middle metatarsal area at both feet. However the plantar pressure of the right medial metatarsal and lateral calcaneal areas was greater than the left, while the plantar pressure of the left lateral metatarsal and medial calcaneal areas was greater than the right. Therefore, supinating and pronating forces were applied to the right and left feet. There were statistically significant differences in body weight and BMI among three groups. The comparison between men and women in plantar pressure measurements and foot type determinations showed that the number of pronated feet group and plantar pressures was greater in males than in females.
Conclusion: The dynamic plantar pressure of teenagers showed high correlation to weight and BMI. Just like the hands, there was lateral dominance at the feet, and analysis of dynamic plantar pressure of each foot showed asymmetry and asymmetrical turning forces.
