WHY ARE POLES IMPORTANT FOR TRAIL RUNNING?
To fully understand the effects of poles in trail running from a scientific perspective, we need to look at it from two angles. First, the biomechanical perspective. The question here is how the body’s movement, especially muscle activity, changes. Second, the metabolic perspective. How do the chemical processes in our body, oxygen uptake, and especially heart rate behave?
BIOMECHANICS
It is clear that using poles relieves the legs and shifts part of the load to the upper body. At the same time, ground reaction and joint forces are reduced. Essentially, the goal is to lessen the strain on the lower limbs, allowing for longer distances to be covered. The lower body has to do most of the physical work during running. Therefore, every percentage of load that can be distributed to the arms, shoulders, and core helps prevent the legs from tiring after countless kilometers and hours of running.
METABOLISM
In summary, most scientific results show a significant increase in oxygen demand, heart rate, and energy expenditure when using poles. Some studies indicate a significantly lower perceived intensity during steeper ascents and downhills. Additionally, lower muscle soreness and faster recovery have been observed, along with increased running speed when using poles. Essentially, when the legs are spared, this is compensated by more intense cardiovascular work.
HOW LONG SHOULD TRAIL RUNNING POLES BE?
For beginners, the ideal pole length can be easily calculated by multiplying your height by 0.7. However, the pole length also depends heavily on personal preference and individual technique. Most professional athletes use longer poles due to their advanced technique. The longer the poles, the more power is generated from the back muscles and less directly from the shoulders. Particularly tall athletes, such as François D’Haene or Jim Walmsley, prefer a pole length of 135 cm. If you're still unsure or want the length calculated exactly, we also have a pole length guide on our website. Just enter your height and select the activity, and you’ll get the optimal length.
SHARK SYSTEM OR REGULAR LOOP?
The choice depends on the runner's individual requirements and preferences. The Shark System is the first grip-loop system specifically developed for trail running. It is the most efficient way to transfer your arm strength to the pole and create propulsion. In very hot temperatures or rocky terrain with many climbing sections, the regular loop may also be beneficial. It allows for a bit more flexibility and room during long ultramarathons.
WHY ARE THERE TRAIL RUNNING POLES WITH DIFFERENT DIAMETERS?
Trail running poles come in different diameters. The “Superlite” poles with 14/12 mm are used by top athletes. As the name suggests, these poles are extremely light. A good comparison is a Formula 1 car – it’s a racing vehicle, but not designed for everyday use. For regular training, we recommend our standard trail running poles with a 16/14 mm diameter.
WHY LEKI TRAIL RUNNING POLES?
