Pacing and Avoiding Performance Predictions

Written by Matt Russ


No athlete likes to be passed during a race. A natural reaction is speed up and attempt to keep pace withrepparttar person whose dust you are now eating, but in doing so you just got pulled out of your game and put into theirs. Most likely you have no idea of their performance potential, pacing, or strategy (if any). Multi-sport events often have a relay team category in which a single athlete will use up everything they have inrepparttar 133129 one leg. The point is, to be truly efficient and race your fastest you must know and race within your limits, not someone else’s. There is only one pace that is most efficient for you and a very fine line between it and over pacing. Proper pacing becomes especially important in distance races such as marathon and Iron Man distance. It is very easy to get caught in a moment and push too hard atrepparttar 133130 wrong time, only to pay for it later.

The scenario athlete who passed you could actually be slower and pacing themselves incorrectly, or a faster athlete who is going to eat your legs up and leave you flat. In either case, if you are atrepparttar 133131 top of your performance envelope chasing them will only slow you down. If you go anaerobic even for a short period of time you are going to have to recover, and recovery takes time. Anaerobic efforts are very fatiguing, especially if you are not trained at these intensities, or to repeat these intensities. It is important to know your performance potential and pace and train yourself accordingly. An athlete should get metabolically tested, or perform performance tests and race simulations to determine such heart rate intensities as lactate threshold and max VO2. These numbers are critical to proper pacing. Where you should be in relation to these heart rates will depend on your race and conditioning. Shorter sprint races may have you at or above LTHR if you are highly trained. Longer endurance races may be mainly at an aerobic level with brief periods above this zone.

Whitetail Deer's Digestive System

Written by David Selman, Tracker-Outdoors.com


Deer are ruminant animals which means they have a four chambered stomach similar to cattle. A fascinating characteristic aboutrepparttar ruminant's stomach is that it allowsrepparttar 133128 animal to gather a lot of food at once and then chew and digest it later. The four chambered stomach is needed to processrepparttar 133129 large amounts of low nutrient food that deer eat in order to getrepparttar 133130 most benefit possible.Depending onrepparttar 133131 type and abundance of food,repparttar 133132 deer can fill its stomach in about one or two hours of grazing. When a deer eats, food is chewed just enough to swallow and store it inrepparttar 133133 first stomach chamber.  The deer has a four section stomach similar to that of cattle. The food goes intorepparttar 133134 first chamber which acts as a fermentation vat. Most ofrepparttar 133135 digestion occurs in this area ofrepparttar 133136 stomach. Deer depend on billions of microorganisms that live in its stomach to break downrepparttar 133137 fibers, cellulose, and other basic plant components, and convert them into materials that can be used byrepparttar 133138 deer's digestive system. Over 40 percent of a deer's energy is derived fromrepparttar 133139 acids absorbed throughrepparttar 133140 walls of its first stomach.
