As aging occurs, what physical changes are commonly observed?

The observation of stiffened joints and decreased endurance is well-supported by research on the effects of aging on the body. As people age, they typically experience a natural decline in muscle mass, known as sarcopenia, which can lead to decreased strength and mobility. Joints often lose flexibility due to changes in connective tissue and cartilage, resulting in stiffness. Additionally, endurance tends to decrease because of changes in cardiovascular efficiency and overall physical conditioning.

These changes can negatively impact daily activities and increase the risk of falls and injury, which is why maintaining an active lifestyle, including strength training and flexibility exercises, is crucial for older adults to counteract these effects and promote overall well-being.
