Soccer, the most popular sport in the world, is played by over 250 million people globally. However, there is growing concern about the potential consequences of heading the ball in soccer, particularly the short- and long-term effects on players’ neurochemistry.
The Impact of Heading on Soccer Players
Heading the ball in soccer often involves collisions with other players, the ground, or even the goalpost. Although most headings do not result in concussion symptoms, studies have shown that the average g-force experienced during heading ranges from 16 to 28g, with peak forces reaching up to 60g. This raises the question of whether repeated heading could lead to subconcussive head impacts (RSHI) and the subsequent neurochemical changes.

Exploring Neurochemical Alterations
Research has already demonstrated alterations in the brain’s white matter microstructure in professional soccer players, even in the absence of concussive brain trauma. Additionally, an association has been found between heading frequency and alterations in cerebral white matter microstructure in amateur players. These findings suggest that soccer players may be at risk for neurocognitive impairment later in life.
Magnetic Resonance Spectroscopy (MRS) Study
A recent study utilized magnetic resonance spectroscopy (MRS) to investigate the long-term effects of subconcussive head impacts on brain chemistry in former professional soccer players without a history of concussion. The study revealed significant alterations in brain chemistry, including increased myo-inositol (mI) and an imbalance of choline (Cho), which indicate glial cell activation and damage to cell membranes.

These findings help shed light on the potential neurochemical consequences of heading the ball in soccer. Understanding the long-term effects of subconcussive head impacts is crucial in order to protect the well-being of soccer players. Further research is needed to explore the effects of subconcussive brain trauma, particularly the impact on gray matter and its implications for neurocognitive function.
FAQs
1. What is subconcussive head impact?
Subconcussive head impact refers to the impact to the head that produces neuronal changes similar to those seen in concussion, but without the immediate symptoms of a concussion.
2. How many headings do soccer players perform on average per game?

On average, soccer players perform 6-12 headings per game, accumulating thousands of headings over the course of their careers.
3. Can heading the ball in soccer lead to neurocognitive impairment later in life?
Studies have shown that soccer players are at a higher risk for neurocognitive impairment later in life, although further research is needed to fully understand the relationship between heading and long-term cognitive consequences.
Conclusion
The study utilizing MRS in former professional soccer players provides valuable insight into the long-term neurochemical alterations resulting from subconcussive head impacts. These findings emphasize the need for proactive measures to protect soccer players from potential neurocognitive impairments. As the discussion surrounding heading in soccer continues, further research is necessary to fully comprehend the impact on gray matter and its implications for players’ overall brain health.
