An anthropological perspective on hand grip strength as a marker of health, disease and fitness

Abstract

Handgrip strength is a quick way to assess overall muscle strength. Low handgrip strength is an indicator of poor health. While handgrip strength is related with mortality and morbidity, for some parameters, handgrip strength is even a stronger predictor of health than chronological age alone. Handgrip strength is highly sexually dimorphic and has a high heritability. It is thought that this is an outcome of sexual selection and intrasexual competition in our evolutionary history. Some anthropological studies confirm this view, and it is claimed that there are relationships between grip strength and aggression, athletic performance and attractiveness, especially in men. The aim of this study is to review the relationship of diseases with handgrip strength in anthropological perspective and examine the idea that handgrip strength being a marker of biological fitness.

Sağlık, hastalık ve uygunluğun bir göstergesi olarak el kavrama kuvvetine antropolojik bir bakış

Öz

El kavrama kuvveti genel kas kuvvetinin ölçümü için kullanılan hızlı, kolay ve güvenilir bir tekniktir. Düşük el kavrama kuvveti, mortalite ve morbidite ile ilişkili olmakla birlikte, yaşlanmaya bağlı sağlık göstergesi olması açısından, kronolojik yaştan bile daha güçlü bir öngörü gücüne sahiptir. El kavrama kuvveti ayrıca yüksek bir kalıtsallığa sahiptir ve yüksek oranda cinsel dimorfiktir. Cinsiyetler arasında gözlenen kuvvet farkının evrimsel tarihimizde cinsel seçilim ve cinsiyet içi rekabet ile de ilişkili olduğu düşünülmektedir. Bazı antropolojik çalışmalar bu görüşü doğrular şekilde, özellikle erkeklerde kavrama kuvveti ile saldırganlık, atletik performans ve çekicilik gibi olgular arasında ilişkilerin olduğunu ortaya koymaktadır. Bu çalışmanın amacı, el kavrama kuvvetinin sağlık, zindelik ve hastalıkların yanı sıra biyolojik uygunluk ile ilişkisini antropolojik bir bakış açısıyla ele almaktır.
