During exercise, expiratory reserve volume decreases because more air is being exhaled to help meet increased oxygen demands. The respiratory rate and depth of breathing typically increases during exercise, which can lead to a decrease in expiratory reserve volume.
This is the amount of oxygen that is reserved in your body while you work out. The more that you work out the more of a reserve volume your body will have.

Exercise is likely to make you more hungry, so if you're not watching your diet that can happen. Muscle is also heavier than fat by volume, so if you've gained muscle mass you can become heavier even if your measurements are the same or even smaller. Don't worry though, more muscle means you can burn more calories during the same length of exercise.
No, the volume of matter does not increase during evaporation. When a liquid evaporates, its molecules escape into the air as gas. Although the molecules are now more spread out in the gas phase, the overall volume remains the same.
it's endorphins... I'm on the same exam now.
Cardiocascular drift refers to the upward drift in heart rate and consequential downward drift in stroke volume (amount of blood pumped by the heart with each beat). This phenomenon occurs during prolonged steady-state exercise, particularly in the heat, and is due to the influence of increasing core temperature on dehydration and reduced plasma volume. Because HR increases and SV decreases, total cardiac output (amount of blood pumped per min- HR X SV) remains the same. However, one must still exercise at a lesser intesnity to avoid fatigue- near maximal heart rates are often observed during such occasions.
Business Volume means: The number of items sold, or the number of shares sold on the Stock Exchange during a day's trading.Example: The Company has maintained the same volume of business in spite of the recession.
There is no reason for the surface area to remain the same even if the volume is the same.
Muscles during exercise need an adequate supply of glucose and oxygen. Heart rate increases during exercise to provide this supply.
Resting heart rate goes down (maximum stays the same).
Muscles need more oxygen and glucose during exercise.They dilate their arteries to receive more blood . At the same time,working muscles push more blood in the veins to the heart.This increases the volume of blood reaching the heart.The heart therefore has to pump harder and faster.
