Abstract

Objective: Increased
pronation in rearfoot can affect daily living activities such as doing sports,
long standing and walking and physical fitness of people by disrupting
biomechanics of foot. The aim of this study is to examine the relationship
between increased pronation in rearfoot and physical performance in young
adults.

Material and Methods: 64 healthy young adults aged 18 to 25 years were included in the study voluntarily. The demographic information of the subjects participating in the study was recorded and the rearfoot pronation was assessed by navicular drop test. The physical performances of the individuals were assessed by vertical jump test, side step test and shuttle running test. Spearman Correlation Analysis was used to evaluate the relationship between rearfoot pronation and physical performance. Statistical significance was accepted as p <0.05.

Results: A statistically significant relationship was found between the navicular drop test and side step test and shuttle running test (p <0.05). As the severity of rearfoot pronation of individuals increased, side step and shuttle running test performances were worsened. There was no statistically significant relationship between the navicular drop test and vertical jump test (p˃0.05).

Conclusions: Increased rearfoot pronation negatively affects physical performance of individuals such as leap and running. Early prevention of increased pronation progression, which is common in young adults, and reduction of future musculoskeletal anomalies and decrease in physical performance is an important issue to be consider in preventive programs.

Arka Ayaktaki Pronasyon Artışının Fiziksel Performans Üzerine Etkisi

Abstract

Amaç: Arka ayaktaki pronasyon artışı
ayağın biyomekaniğini bozarak,
kişilerin spor yapma, uzun süre ayakta kalma ve yürüme gibi
günlük aktivitelerini ve fiziksel uygunluğunu etkileyebilmektedir. Bu çalışmanın
amacı genç yetişkinlerde arka ayakta pronasyon artışıyla fiziksel performans
arasındaki ilişkinin incelenmesidir.

Gereç ve Yöntem: Çalışmaya 18 ile 25
yaş arası 64 sağlıklı genç yetişkin, gönüllü olarak dahil edildi. Çalışmaya katılan
bireylerin demografik bilgileri kaydedilerek arka ayak pronasyonu navikular
düşme testi ile değerlendirildi. Bireylerin fiziksel performansları ise dikey
sıçrama testi, side step testi ve mekik koşu testi ile değerlendirildi. Arka
ayak pronasyonu ile fiziksel performans arasındaki ilişkinin
değerlendirilmesinde Spearman Korelasyon Analizi kullanıldı. İstatistiksel
anlamlılık değeri p<0.05 olarak kabul edildi.

Bulgular: Navikular
düşme testi
ile side step testi ve mekik koşu testi arasında istatistiksel olarak anlamlı
bir ilişki bulunmuştur (p
<0.05). Bireylerde arka ayaktaki pronasyon şiddeti arttıkça side step
testi ve mekik koşu testi performanslarının kötüleştiği görülmüştür. Navikular
düşme testi ile dikey sıçrama testi arasında istatistiksel olarak anlamlı bir
ilişki bulunmamıştır.

Sonuçlar: Arka ayak pronasyonunun artması  bireylerin sıçrama ve koşu gibi fiziksel
performanslarını olumsuz etkilemektedir. 
Genç yetişkinlerde sıklıkla görülen artmış pronasyonun ilerlemesinin
erken dönemde önlenmesi ve ileride oluşabilecek muskuloskeletal anomalilerin ve
fiziksel performanstaki düşüşlerin en aza indirilmesi, koruyucu programlarda
ele alınması gereken önemli bir konudur.
