Kaip silpnai žmogus spaudžia dinamometrą, rodo, kokia tikimybė, kad jis greitai numirs

Raumenų silpnumas stipriai koreliuoja su tikimybe numirti, ilgai neužtrunkant. Vidutinis dinamometro spaudimo stiprumas yra 300 niutonų. Kiekvienas sumažėjimas 50-čia niutonų koreliuoja su 16 procentų padidėjančia tikimybe greitai numirti [1].

Rankos paspaudimo stiprumas priklauso nuo kultūros, todėl neatspindi sveikatos.

1. The average grip strength the team recorded was 300 newtons (the force needed to hold a 30.6 kilogram weight against Earth’s gravity). Every 50-newton drop below this was associated with a 16% rise in the risk of death, and a 17% increase in the risk of dying in particular from heart disease. It was also associated with a 7% greater risk of having (but not necessarily dying from) a heart attack, and a 9% rise in the chance of having a stroke. Among those with cancer or chronic heart disease, the strong-gripped were more likely to survive the follow-up period than the limp. The correlation held when the researchers corrected for other factors known to play a part in death rates, including age, education, drinking and smoking.
