Purpose: Hypertension (HT) can exacerbate impaired blood pressure regulation and thus increase the
risk of falls. The higher incidence of HT and impaired balance in older adults may lead to the hypothesis
of an association between HT and physical function in older individuals. The purpose of this study was to
investigate the effects of HT on muscle strength, balance, and mobility in older adults and the
relationship between them.
Methods: Sixty-one older adults were included in the study and individuals with systolic blood pressure
≥140 mmHg or diastolic blood pressure ≥90 mmHg formed the Hypertensive group (n=31), while the
others formed the Normotensive group (n=30). Quadriceps Femoris (QF) muscle strength was
evaluated with a hand-held dynamometer, mobility was evaluated with the Timed Up and Go Test (TUG),
balance performance was evaluated with the Nintendo Wii Fit Balance Board (NWBB), and physiological
age was evaluated with Wii Fit Age (WFA). The systolic and diastolic blood pressure were measured
before the balance test.
Results: TUG and NWBB scores between groups were significantly better in the Normotensive group
(p<0.05). In both Hypertensive and Normotensive groups, there was a negative correlation between QF
muscle strength and TUG score, and a positive correlation between QF muscle strength and NWBB
score (p<0.05).
Conclusion: HT may worsen mobility and balance in older adults. Further studies are required to better
understand HT and establish better appropriate interventions for older hypertensive adults.

Yaşlı erişkinlerde hipertansiyonun kas gücü, denge ve mobiliteye etkisi

Öz

Amaç: Hipertansiyon (HT), kan basıncı regülasyonunda bozulma ile şiddetlendirerek düşme riskini
arttırabilmektedir. Yaşlı erişkinlerde daha yüksek HT insidansı ve bozulmuş denge, HT ile fiziksel
fonksiyonlar arasında bir ilişki olduğu hipotezine yol açabilmektedir. Bu çalışmanın amacı, yaşlı
erişkinlerde hipertansiyonun kas kuvveti, denge ve mobiliteye etkisini ve onlarla ilişkisini incelemekti.
Yöntem: Çalışmaya 61 yaşlı birey dahil edildi ve sistolik kan basıncı ≥140 mmHg veya diyastolik kan
basıncı ≥90 mmHg olan bireyler Hipertansif grubu (n=31), diğerleri Normotansif grubu (n=30) oluşturdu.
Quadriceps Femoris (QF) kas gücü dinamometre ile, mobilite Zamanlı Kalk ve Yürü Testi (ZKYT), denge
performansı Nintendo Wii Fit Balance Board (NWBB) ve fizyolojik yaş Wii Fit Age (WFA) ile
değerlendirildi. Denge testinden önce sistolik ve diyastolik kan basıncı ölçüldü.
Bulgular: Gruplar arasında ZKYT ve NWBB skorları, Normotansif grubunda anlamlı olarak daha iyiydi
(p<0,05). Hem Hipertansif hem de Normotansif grubunda, QF kas kuvveti ile ZKYT skoru arasında
negatif yönde, QF kas kuvveti ile NWBB skoru arasında pozitif yönde anlamlı ilişki bulundu (p<0,05).
Sonuç: HT, yaşlı erişkinlerde mobiliteyi ve dengeyi kötüleştirebilmektedir. HT'yi daha iyi anlamak ve
yaşlı hipertansif yetişkinleri için daha uygun müdahaleler oluşturmak için daha fazla çalışmaya ihtiyaç
vardır.
