Which component of fitness is particularly affected by obesity?

The correct response is that cardiovascular endurance is particularly affected by obesity. Cardiovascular endurance refers to the ability of the heart, lungs, and blood vessels to supply oxygen to the working muscles during sustained physical activity. Individuals with obesity often experience an increase in body mass and fat levels, which can place additional strain on the cardiovascular system. As a result, the efficiency of oxygen transport and utilization can be compromised, leading to reduced endurance.

When engaging in activities that require sustained effort, those with higher levels of body fat may find it more challenging to perform due to this decreased aerobic capacity. This can manifest in quicker fatigue and a lower overall performance level in aerobic activities like running, swimming, and cycling. Because cardiovascular endurance is essential for overall fitness and health, particularly in physical activities, its decline is a significant concern associated with obesity.
