Özet
Amaç: Bu çalışmanın amacı, el kavrama kuvvetinin (HGS) yaşlı yetişkinlerde fiziksel ve bilişsel fonksiyonlar üzerindeki yordayıcı rolünü incelemek ve özellikle alt ekstremite performansı, aerobik kapasite, denge ve bilişsel işlevlerle ilişkisini değerlendirmektir.

Yöntem: Çalışmaya 60 yaş ve üzeri 66 yaşlı yetişkin dahil edilmiştir. HGS, dinamometre ile ölçülmüştür. Alt ekstremite performansı Otur-Kalk Testi (STS) ve Karşıt Hareket Sıçrama Testi (CMJ) ile; aerobik kapasite İki Dakika Yürüme Testi (2MWT) ile değerlendirilmiştir. Bilişsel fonksiyonlar ise Sembol Rakam Modaliteleri Testi (SDMT) ve Raven Standart İlerleyen Matrisler Testi (RSPMT) ile ölçülmüştür.
Bulgular: El kavrama kuvveti, alt ekstremite performansı ve bilişsel fonksiyonlarla pozitif yönde ilişkili bulunmuştur. HGS’nin STS (r = 0.249), CMJ (r = 0.284), 2MWT (r = 0.333) ve SDMT (r = 0.378) ile anlamlı ilişkileri tespit edilmiştir (p < 0.05). Regresyon analizleri, HGS’nin fiziksel performans değişkenlerindeki varyansın %9–13’ünü ve SDMT skorlarının %25’ini yordadığını göstermiştir.

Sonuç: Bu çalışma, el kavrama kuvvetinin yaşlı yetişkinlerde hem fiziksel performans hem de bilişsel işlemleme hızının anlamlı bir göstergesi olduğunu ortaya koymuştur. HGS’nin STS, CMJ, 2MWT ve özellikle SDMT ile olan ilişkileri, çok boyutlu fonksiyonel kapasitenin değerlendirilmesinde pratik bir araç olabileceğini göstermektedir. Bulgular, HGS’nin fonksiyonel düşüş riski taşıyan bireyleri belirlemede klinik değerlendirmeleri destekleyebileceğini düşündürmektedir. Fiziksel ve bilişsel yaşlanmaya yönelik yordayıcı değerinin daha net anlaşılması için uzunlamasına çalışmalara ihtiyaç vardır.

Abstract
Objective: The study examines the predictive value of HGS for physical and cognitive functions in elderly, particularly its specific association with lower limb performance, aerobic capacity, balance and cognition.
Method: A total of sixty-six older adults aged 60 or above participated. HGS was assessed by dynamometer. Performance of lower extremity was assessed by the Sit to Stand Test (STS) and Counter-Movement Jump Test (CMJ). Aerobic performance was evaluated by the Two Minute Walk Test (2MWT). Cognitive abilities were tested using the Symbol Digit Modalities Test (SDMT), and Raven’s Standard Progressive Matrices Test (RSPMT).
Results:. HGS was positively associated with both physical and cognitive performance. Moderate correlations were made with STS (r = 0.249), CMJ (r = 0.284), 2MWT (r = 0.333) and SDMT (r = p <0.05). Regressions showed that HGS accounted for 9–13% of the variance in physical performance and 25% of SDMT scores.

Conclusion: The results provide evidence that HGS is a significant predictor of physical performance functioning and cognitive processing speed in older. Its correlations with STS, CMJ, 2MWT and SDMT indicate that HGS may also function as a feasible multi-dimensional functional capacity. These findings provide supportive evidence for integrating HGS testing in the clinical evaluation, aiming to identify who is at risk of functional limitation. Additional longitudinal studies are warranted to elucidate its predictive role in physical and cognitive aging.
