The relationship between age and muscle mass is often characterized by a natural decline in muscle strength and size, a condition known as sarcopenia. As individuals age, hormonal changes and reduced physical activity contribute to this decline. Maintaining a regular strength-training routine can mitigate muscle loss, helping older adults preserve their muscle strength and function. Proper nutrition, particularly adequate protein intake, is also essential for supporting muscle health as one ages. Staying active is key to preserving mobility and independence in later years.
