The test score is the time taken on the test, in minutes. This can also be converted to an estimated maximal oxygen uptake score using the calculator below and the following formulas, where the value "T" is the total time completed (expressed in minutes and fractions of a minute e.g. 9 minutes 15 seconds = 9.25 minutes). As with many exercise ...
Beta-blockers slow the heart rate, lowering blood pressure and making the heart beat less forcefully. They’re prescribed to treat and prevent heart attacks, high blood pressure, and chest pain ...
