Sovi eone who might Over Overl could use it o control his in Rise gut for Iho general population a we of Tulip jul i just As Uso Lul a  a primary reason to exercise of course in to achieve cardiovascular fitness it is Well established that the Fil person s heart beats More slowly Bolh at real and during exercise. A resting heart Rale Lor a Sec Tenary person might be 70 teals per minute while a highly lit person s rate might be so during moderate sucrose the sedentary person s Rala will shoot up to 150, while the lit person s i Flat Roach Only 100. Over a lifetime a lit person s heart beats perhaps 1 billion fewer times in a comparable lifespan. The Assumption is Ihal a Hearl thai works less lakes longer to Wear out although thare ate no definitive medical studies that prove this. Bui the real measure of fitness is not heart Rato but the body s ability to take up oxygen through the respiratory system and deliver it to the cells where it combines with Glycogen provided by Loed to create Energy the More lit we Are the More blood the heart can pump and the More oxygen can be carried to the Colls. If you gasp for breath during a modest jogging session and feel inferior to joggers who Are not panting it is because their cardiovascular and respiratory systems have no difficulty sending enough oxygen to the cells. Because a Cir body is less til oxygen supplies at the cellular level Tecoma ,1 problem More quickly. When you slow Dovin or Slop or a minute or two and walk oxygen Supply to inc muscle cells has an Opportunity to catch up. Wilh Loo much exertion even in a lit person Iho oxygen Supply is depleted and Malabo film crosses a threshold irom aerobic to an Robic. This is the breathless Ness that maximum exertion brings. In the research Laboratory oxygen delivery can be measured precisely by collecting and analysing exhaled breath during exercise in a Treadmill or stationary bicycle. Bui without such expensive equipment doctors rely on the Hearl Rae since increases in Iho heartbeat roughly parallel oxygen transport. Ii you Are 40 years of.

You doubtlessly would be Over the aerobic thrash hold. If you exercised until it reached 153, you would to exercising near the limit o your body s ability to deliver oxygen to the cells without moving to aerobic exercise although Here is much variability in these heart rate Levels from person to person. But cardiologists such As Thompson and Hask Cli say this theoretical notion founders on the realities of human variability. Target heart rate is based on All people but in the individual it can vary plus or minus about 15 or 20 beats per minute. The larger heart Rale is really lha grosses approximation Thompson said. A Palione will Tell me. I m pushing As hard As i can and i still cannot gel up to my target heart rate that s because of he variability from person to person people need to realize it s just another tool to assist somebody in trying to establish a suitable exam also smoked out by legislation by Peg Byron United press International Eady on not american Solors Are cutting Down on where and when they Light up because increasingly the Law in the United status is giving them no Choice Over 100 municipalities and is slates have Resari Clad Molung in certain Public areas.
