The primary source of energy for physical activity, particularly in elderly individuals, is carbohydrates. Carbohydrates are quickly metabolized by the body to provide immediate energy for muscle activity. During physical exercise, especially at higher intensities, the body relies on glucose derived from carbohydrates for quick energy.

While fats can also serve as a source of energy, their metabolic conversion is slower and typically utilized during lower-intensity exercises or at rest. Proteins primarily function in repairing tissues and supporting bodily functions rather than being a primary energy source. Vitamins play crucial roles in metabolic processes but do not provide energy themselves.

Therefore, for elderly individuals engaging in physical activities, carbohydrates are essential for meeting energy demands effectively and are vital for sustaining performance and maintaining muscle mass.
