What is a primary cause of frailty in later years?

A physically inactive lifestyle is a primary cause of frailty in later years because it leads to a decline in muscle strength, endurance, and overall physical function. Regular physical activity is crucial for maintaining muscle mass, bone density, and cardiovascular health. When individuals do not engage in regular exercise, they may experience sarcopenia, which is the age-related loss of muscle mass. This reduction in muscle strength can increase the risk of falls, weakness, and overall dependence, contributing to the development of frailty.

Being inactive can also have negative effects on metabolic health, leading to conditions like obesity and insulin resistance, which further exacerbate frail conditions. Overall, an inactive lifestyle hinders physical resilience and the ability to perform daily tasks, significantly impacting quality of life and independence in older adults.
