Masters athletes, who typically are older adults actively engaged in physical training and competition, often experience various physiological changes as a result of their training and lifestyle. One aspect that does not typically increase in these athletes is bone density. In fact, regular physical activity combined with resistance training can help maintain or even increase bone density, especially in older adults. However, masters athletes, depending on their training focus, can experience differences in bone density compared to the general older population, where non-active individuals may exhibit a decline in bone density due to aging accelerators.

The other options, such as fat mass, body fat percentage, and risk factors for heart disease, can often increase or be exacerbated in the aging population. This is primarily due to metabolic changes, lifestyle factors, or a decrease in physical activity in those who do not engage in structured athletic training, thus leading to higher levels of these risk factors. Therefore, the physiological aspect that does not typically increase among masters athletes is bone density, as their training usually supports its maintenance or improvement.
