Ergonomics & Biomechanics: Why Your Body Is Part of the Setup

Beitrag von Miki »

SimRacing is a competitive sport for both the brain and the joints. Sitting incorrectly doesn't just cost you lap time; it risks long-term injuries like "brake shin" or carpal tunnel syndrome.

1. Power Transfer: The Aluminum Profile Rig (80/20)

A rig is not a piece of furniture; it is a static foundation.

Flex Analysis: Manufacturers like Sim-Lab (P1-X) or Trak Racer (TR160) use 160mm x 40mm profiles for the base. Why? When driving a Simucube 2 Pro with 25Nm, torsional forces are created that will cause a thinner rig (e.g., Playseat or cheap tube frames) to vibrate and flex.

The "Loss of Detail": Every millimeter of movement in the rig is information from the wheelbase that does not reach your hands. A stable rig makes you more precise.

2. Pedal Geometry & Braking Force

Angle & Height: With high-end pedals like VRS DirectForce or Heusinkveld Ultimate, the height of the pedal plate is crucial for the leverage arm.

GT vs. Formula:

GT Position: Hips and feet almost on the same level. Allows high pressure from the thigh muscles.

Formula Position: Feet significantly above the hip line. Here, the power comes from the lower back and core muscles.

Biomechanics Trick: The brake pedal should be set so stiff that you only reach 100% braking force with maximum effort. This prevents "panic locking" or over-braking in heated situations.

3. FOV & Monitor Technology

Panel Types: Use OLED or IPS with at least 144Hz. VA panels tend to suffer from "ghosting" (blurring), which makes it harder to judge distances in fast corners.

Monitor Distance: Every centimeter the monitor is closer to your eyes increases your natural FOV. Goal: The monitor should be positioned directly behind or even above the steering wheel shaft.
Mir geht es gut weil ich ein Mann bin! :D
