Mitochondria are often called the “powerhouses” of the cell because they produce the energy that every cell needs to function. In muscle cells, this energy is essential for repairing small muscle strains that occur during training. Healthy, active mitochondria ensure that muscle fibres recover faster, grow stronger, and maintain flexibility.

ATP (Adenosine Triphosphate) is the energy molecule that powers every cell. When ATP levels are high, cells can repair and regenerate more efficiently, which directly translates into stronger muscles, better endurance, and improved resilience to strain. For horses, this means not only faster recovery after exercise but also a reduced risk of overuse injuries.

Specific wavelengths of LED light penetrate tissue and are absorbed by the mitochondria. This stimulation increases ATP production, boosts circulation, and reduces inflammation, all without invasive procedures or medications. In essence, the treatment supports the body’s normal repair processes, helping the body do what it is already designed to do, but faster and more effectively.

Both technologies rely on the same biological principle: photobiomodulation.

Laser devices deliver concentrated light from a single point. LED systems distribute light across a larger treatment area, making them suitable for muscles, tendons and joints in horses.

This allows consistent coverage without the need for precise positioning during treatment.

Light interacts with biological tissue differently depending on the wavelength used. Some wavelengths act closer to the surface, while others penetrate deeper into muscles, tendons and joints.

For photobiomodulation to work effectively, the light must fall within the optical window, a range where biological tissue allows light to pass through and reach the cells.

LED by CHEVAL systems use four selected wavelengths of red and infrared light between 660 and 850 nm. Together, they support both surface level tissue and deeper anatomical structures during each treatment session.
