What does RER mean in PHYSIOLOGY

The Respiratory Exchange Ratio (RER) is a ratio of carbon dioxide produced to oxygen consumed during respiration. This ratio helps to determine the amount of energy that the body uses during physical activities like running or exercising. It's also used to assess how efficiently a person's body is using oxygen when compared to other people.

The Respiratory Exchange Ratio (RER) can be measured in two ways. One way involves collecting expired air samples and measuring the ratios of carbon dioxide and oxygen. Another method involves using indirect calorimetry, which measures the metabolic rate of energy production for physical activity from heat production.

Yes, RER is an important metric as it helps to measure how efficiently a person's body uses oxygen when compared to others and shows how efficient their body is utilizing energy during physical activities like running or exercising. By understanding the RER, it allows athletes and trainers alike to create more effective training programs that will get them closer to their goals in a shorter time frame.

Athletes and active individuals who are looking for ways to maximize their performance may want to consider tracking their RER regularly as it provides useful insights into how well their bodies utilize oxygen when compared with other people and can help inform better training strategies tailored specifically for them.

A high respiratory exchange ratio usually indicates that the body is producing more carbon dioxide than it needs, which suggests that the metabolism could be running inefficiently due to lack of exercise or poor eating habits. A low respiratory exchange ratio usually means that not enough carbon dioxide is being produced, which can suggest that aerobic fitness levels are lower than they should be for optimal performance.

Since different people have different metabolic rates, there isn't one standard value for respiratory exchange ratios (RER). It largely depends on factors such as age, gender, health status, diet, etc., so it’s best for individuals monitor theirs on an individual basis rather than comparing themselves against someone else’s values directly.

Yes - higher altitudes tend to increase an individual's respiratory exchange ratio due to decreased atmospheric pressure and increased air density leading up higher altitudes causing respiration systems work harder than normal which in turn increases an individual's RER values temporarily. However this can vary depending on various external factors like acclimatization period etc..

Yes - Regular exercise combined with proper nutrition has proven effective at improving an individual’s respiratory exchange ratios over time so by making exercise and sensible eating habits part of your daily routine you should see improvement in your scores gradually.

Yes - Hydration levels have been found to have a direct effect on respiratory exchange ratios with dehydration leading towards lower scores whereas being well hydrated tends towards higher scores.
