How Does Exercise Affect The Rate Of Cellular Respiration
Exercise: In order to facilitate the increase in oxygen demand of the muscles during exercise, the heart rate and volume of blood per beat will go up. Cardiac output is the product of heart rate times stroke volume. Therefore cardiac output will increase with exercise. ...Read moreSee 1 more doctor answer
Exercise Or Physical Activity (Definition)
Exercise is a physical activity that is completed to maintain or improve health. Benefits of exercise include weight maintenance, improving mood, increasing energy, preventing or controlling chronic diseases, promoting better sleeping, and improving sex life and libido. ...Read more
Clearance of drugs.: This depends on your muscle and fat and the drug. I would Goolge drug metabolism for a more detialed answer. Also can go to drugs.com and check how different drugs can affect the metabolism of other drugs. ...Read more
Cardiac drift: With prolonged exercise, breathing rate increases to meet the oxygen demands of working muscle. Heart rate increases, but it does not plateau. A steady increase in heart rate is seen with prolonged exercise due to 'cardiac drift'. The heart rate increases in order to maintain your cardiac output in the face of decreased 'preload' due to dehydration and blood diverting to skin for heat loss. ...Read moreSee 1 more doctor answer
Temp and enzyme:
Great wikipedia question. Heat makes molecules move faster and can get in and out of enzyme active site faster.

Depends on cause: Multiple etiologies of CNS inflammation exist, many of which are chronic (infection more acute or subacute). Using the model of ms, we can see cognitive loss, fatigue, weakness, numbness, imbalance or incoordination, loss of vision, problems with bowel/bladder fnctn. So given this ballpark approach, different disorders can affect general fnctn. ...Read more
It shouldn't : If the pacer is set properly and one is pacer dependent, the heart rate is set. Different settings may be set up so that if the heart rate increases or decreases the pacer will start up and take over at a predetermined rate. Other symptoms of anxiety or nervousness or cramps may occur. ...Read more
Exercise increases the size of the heart, hypertrophy. How does this differ from cardiomyopathy and damage to the heart?
Hypertrophy/cardiomy: Just like skeletal muscle will increase in muscle mass to incresae strength of contraction .This is a compensatory response to increase the force of contraction. However, as the heart muscle increases in size it everntually will decrease the size of the heart chamber (ventricle) and decreases the volume of blood in the ventricle. ...Read more
Activity Level: The heart rate of an individual varies with activity level all through the day. The most commonly alluded to figure is the resting heart rate, which is the number of times the heart beats at per minute while the subject is at rest. In adults it averages around 72bpm, but can approach 200bpm with high level of activity. In conditioned athletes, resting heart rate could be as low as 50bpm or less. ...Read more
Millisecond timing: The 2 atria act as reservoirs for returning blood; the 2 ventricles are the "pumpers". The 4 chambers must be coordinated with millisecond timing to maximize the amount of blood pumped (cardiac output). This is done by a network of specialized cells which are found in tracts or bundles that conduct a micro-electrical current to time motion. A gross analogy: think of the distributor in your car. ...Read more
Certain medications: Certain medications obscure the ekg changes, or the exercise capacity reducing the utility of the test. Abnormalities of the resting ekg may also impair accuracy. Nuclear scans or echocardiographic images before and after exercise may be performed and may allow a diagnostic test even in these circumstances and also increase the diagnostic accuracy. ...Read more
Not an easy answer: when a persons body temp goes up asi fever, the mechanisms that help with cooling invoke increased respiration, perspiration, and vasodilation of the blood vessels. Since heart rate increases to maintain cardiac output with vasodilation, blood pressure is usually not affected, but may drop a small amount ...Read moreSee 1 more doctor answer
Can't be answered: There's a lot of confusion about serotonin by the public, in part because some antidepressants are said to work by "increasing serotonin." it's not so simple. Serotonin is a neurotransmitter (it carries signals between nerve and brain cells) that acts throughout the body. There's no single "level" of serotonin in the body, ; it doesn't increase or decrease as a whole. ...Read more
