The muscles get their energy primarily from the breakdown of carbohydrates. For this "burning" (or: "metabolism") oxygen is used if possible. There is enough oxygen, this happens under aerobic conditions. Increase movement speed, the oxygen is scarce, and the cells are forced to reduce carbs without oxygen. This is called anaerobic (without oxygen). Lactic acid, lactate also arises in such conditions as a breakdown product called, which must be reduced in various institutions - mainly in the liver. More lactate than can be reduced, resulting in a greatly increased intensity are your muscles "through" and the body forces you to a significant reduction in the intensity of your load.
Where is the "threshold"?
You are running at your anaerobic threshold (at the), when Laktatbildung based bone formation and bone resorption around the scale. You can maintain such an intensity just about an hour long. A 10-km run läuftst you so easily or clearly about your personal to, depending on what time you for this need. Depending on the level of performance, the anaerobic threshold is set at about 90 to 94% of your maximum heart rate. Targeted training increases the value.
Training sessions at the anaerobic threshold "Buffer substances" are formed, which could from Huff the lactate falling at high Belastungsintensitäten and allow a greater acidification, go down as the untrained. As a result, a higher tempo can be endured longer.
Good foundation important
A workout at the anaerobic threshold is only useful if you have trained your basic endurance on low pulse level long time. If you train too early with intensive units, you inevitably do break your "form".
Workouts are very effective, but also very stressful for the body at the anaerobic threshold. Therefore, such units only in the preparation of the competition should be completed. The next day, you should not intense exercise, but incorporate a maximum a regenerative, loose unit (super compensation). Runners who train for years can expect of course more himself.
Many runners disregard the important rule: not the exercise makes you faster, but the break in between. For this reason, I recommend you first read through the theme of regeneration.
Long threshold training make sense. Usually you completed an such speed endurance runs about 20 to 30 minutes or interval training with the appropriate intensity.
The anaerobic threshold area
The anaerobic threshold range is approximately 88 to 94% of your maximum heart rate. Sports medicine performance tests, you can set this threshold area relatively precisely.
Without performance test, you can determine the approximate personal threshold pace with a 10 km run. In the table you can see your approximate to the tempo with results of competition or test run results. You want a personalised table, so go to the speed table.
Calculation of intervals
If you want to know how quickly, you should complete a stretch of 200 or 400 m in your threshold pace, you can calculate this as:
Formula:
3.6 x (multiplied) distance in meters: (divided by) the speed (in km/h) = time in seconds
Invoice sample at a threshold pace of 12.7 km/h and 400 m - track interval: 3.6 x 400 m / 12.7 km/h = 113 s = 1 min 53 sec for 400 m
