FEV, ERV, IRV and VC will increase in a person who is fit cardiovascularly. This is generally the case for swimmers and runners.
VO2 Max would be the most likely because it determines a person's maximum threshold to perform cardiovascular exercise
While it is likely that no respiratory volumes are really considered exaggerated, a better word might be increased. In the case of a person that has cardiovascular fitness the most noticeable increase would likely be in vital capacity.
In a person who has smoked heavily for over twenty years, the total lung capacity (TLC) and residual volume (RV) are likely to be exaggerated. Chronic smoking can lead to emphysema, causing the air sacs in the lungs to become damaged and lose elasticity, resulting in increased air trapping and a higher residual volume. Additionally, the overall lung capacity may increase as the lungs adapt to chronic obstruction, leading to a larger total lung capacity.
One example is the spirometer.
It decreases Residual Volume

I don't know. That's what I am looking for.
COPD can affect the rate and depth of breathing including respiratory volumes. A stress test will also show irregular changes.
Respiratory volume is defined as how much air a person can hold in their lungs. Respiratory volume can be measured by having the person take a deep breath, and blow out into a device that measures air capacity.
Low lung volumes indicate a reduction in the amount of air that the lungs can hold, which can result from restrictive lung diseases, obesity, or neuromuscular conditions. It may lead to decreased oxygen exchange and respiratory difficulties. Clinically, low lung volumes are often assessed through pulmonary function tests, which can help diagnose underlying conditions affecting lung capacity. Overall, addressing low lung volumes is essential for improving respiratory health and quality of life.
The answer depends on what you mean by measurable. Modern inkjet printers deposit inks in volumes of just a few picolitres (trillionth of a litre or billionth of a millilitre). Smaller volumes can be measured and the limit, presumably is the Planck volume = approx 4.22*10-99 millilitres.
Several variables can affect the measurement of respiratory volumes in an individual, including age, sex, body composition, and physical fitness level. Factors such as body position (sitting vs. standing), respiratory rate, and the presence of respiratory conditions (like asthma or COPD) can also influence results. Additionally, environmental factors, such as altitude and temperature, may play a role in lung function and volume measurements. Lastly, the technique and equipment used during the measurement can introduce variability.
