2. Multiple studies have found that artificial turf can lead to increased risk of injury, particularly in
field sports like soccer. Researchers from the Department of Sports Biomechanics of Kharazmi
University in Tehran, Iran analyzed 76 articles that looked into artificial turf and injuries from
international scientific databases.
Their analysis indicated that the surface of artificial turf is harder and absorbs less shock than
natural grass. Its materials also cause too much friction. Both these qualities can contribute to higher
injury rates than would have occurred on natural grass. Another study, conducted by Pennsylvania
State University, pointed out that the materials for artificial turf lead to increased surface
temperatures, which could also impair athletes.

3. Not Enough Shock Absorption, Too Much Friction
Kharazmi University's analysis found that many studies say artificial turf is a poor playing surface
because of its hardness. This can cause foot pain among younger athletes and make it harder to run
or jump. The researchers included a survey of soccer players that reports surface hardness as a
contributor to their injuries.
Studies also say that artificial turf has increased surface friction. This can put excessive force on
joints, muscles, and bones when athletes stop or change directions. The friction increases when the
material is dryer and has less moisture.
Hotter Than Natural Grass
A paper published by the Department of Crop and Soil Sciences of Pennsylvania State University
found irrigation systems could only lower the surface temperature of artificial lawns for short
periods. The researchers noted that the surface temperature of artificial turf could reach up to 93
Celsius or 199.4 Fahrenheit, which can have serious adverse effects on athletes. No method tested by
the researchers could lower the temperature for long periods.
These factors may be the reason that international sporting associations, such as FIFA, prefer to use
natural grass on their playing fields. Until such time that artificial lawn technology can solve these
issues, private and commercial lawns can benefit from well-maintained natural grass.
