Most trees have their diameter measured at breast height, which is considered to be four and a half feet above the ground on the uphill side of the tree. Sierra redwoods however, are measured at six feet above the ground. This is because of the major increase in circumference at the lower end of the tree.
With a higher exercise intensity the lactate level in the blood reaches the anaerobic threshold (AT), or the onset of blood lactate accumulation (OBLA).ccurately measuring the lactate threshold involves taking blood samples (normally a pinprick to the finger, earlobe or thumb) during a ramp test where the exercise intensity is progressively increased.
lactate dehydrogenase (LDH) test, a blood test used to detect levels of LD, which is widely distributed throughout the body. Disease or injury to body tissues such as the heart, liver, red blood cells, kidneys, skeletal muscles, brain, and lungs will result in higher-than-normal blood levels.actate dehydrogenase (LDH) test, a blood test used to detect levels of LD, which is widely distributed throughout the body.
