They are increasing because you need energy for the first few minutes of the race after that few minutes is up the body will start to produce ATP through aerobic respiration again and get it to the muscles. that is also how marathon runners can stay running for so long.
Fasting basically means not having any glucose. This is a good idea to do before testing your glucose levels as it gives you a more accurate number and will allow you to gauge how much glucose you have in your system.
Glucagon is the hormone that raises blood glucose levels.
Glucose levels in urine typically increase after meals when blood glucose levels rise. Glucose excretion in urine is typically higher when blood glucose levels are elevated, such as in uncontrolled diabetes.
Yes, glycogenolysis is the breakdown of glycogen into glucose, which can increase blood glucose levels.
Glucagon is catabolic and increases blood glucose levels, insulin is anabolic decreases blood glucose levels.
when a diabetic is going through puberty or is sexually active the levels of blood sugar can drastically shift due to common changes in the body that is happening during this time.
Adipose tissue is dependent on plasma glucose levels for energy storage and regulation of metabolism. It can uptake glucose from the bloodstream and store it as fat when glucose levels are high.
The liver helps regulate glucose levels in the blood by storing excess glucose as glycogen when levels are high and releasing glucose into the bloodstream when levels are low. It also helps convert other substances into glucose through a process called gluconeogenesis.
When testing blood glucose levels randomly throughout a day the results can vary but as long as they do not vary widely then this doesn't indicate a serious problem. In general normal levels are 80-120 mg/dL before meals or when waking up, 100-140 mg/dL before bedtime.
Insuline and Glucagon control blood glucose. Insuline: brings down high levels of glucose. Glucagon: brings glucose levels back to normal, (brings glucose levels up).
Insulin
Cortisol release can increase blood glucose levels.
