What happens to aerobic capacity as an individual ages, assuming no change in activity level?

As individuals age, there is a well-documented decline in aerobic capacity, primarily influenced by physiological changes that occur over time. This reduction in aerobic capacity, primarily measured as VO2 max, tends to occur steadily and predictably, leading to a linear decrease when factors such as activity level remain consistent. Several factors contribute to this decline, including a decrease in maximal heart rate, reduced efficiency of oxygen utilization in skeletal muscles, and a general decrease in muscle mass and function. As the cardiovascular system and muscular endurance systems naturally decline with age, the body's ability to perform sustained aerobic activities diminishes, leading to an overall reduction in aerobic capacity. Maintaining regular physical activity can mitigate this decline to some extent, but without an increase in activity level, the linear decrease in aerobic capacity remains a consistent outcome throughout the aging process.
