When I was in recruitment I conducted the physical testing for applicants. Strength, agility, sprinting etc.
Before the testing they would have to produce certain health related documents from their physicians and I would take their Blood Pressure and Heart Rates to ensure they met the criteria before they started the testing.
These were all very healthy young adults, however it would never fail that I would have to decline a few from participating because of their BP & Heart Rate readings. Some of them, depending on the brand they drank had a resting BP in excess of 150/90 and resting heart rates of 100 plus.
So if you have hypertension or borderline I'd shy away from them.
