Osmosis from Elsevier - Knowledge Shot: Concussions
The discussion focuses on the dangers of concussions in sports, highlighting that repeated tackles and collisions in football can lead to traumatic head injuries. Concussions, also known as mild traumatic brain injuries, often result from a hit to the head, affecting a large part of the brain. While football is commonly associated with concussions, they also occur in other sports, notably in female soccer players in American high schools, due to less protective gear and practices like headers. The video explains two main types of concussion injuries: coup-contrecoup and torque injuries. Coup-contrecoup injuries involve the brain hitting the skull at the point of impact and then on the opposite side. Torque injuries involve rotational forces causing the brain to twist, potentially affecting the reticular formation, which controls consciousness. Symptoms of concussions include loss of consciousness, seizures, confusion, and sensitivity to light and noise. Coaches are advised to err on the side of caution and remove athletes from play if a concussion is suspected.
Key Points:
- Concussions are common in football and soccer, especially among female high school soccer players.
- Coup-contrecoup injuries occur when the brain hits the skull at the impact point and opposite side.
- Torque injuries involve rotational forces that can affect consciousness.
- Symptoms of concussions include blackouts, seizures, and confusion.
- Coaches should remove athletes from play if a concussion is suspected.

1. ⚽ The Debate on Concussions in Sports
- Concussions, also known as mild traumatic brain injuries, are a significant concern due to repeated tackles and collisions in sports like football.
- Such impacts can result in diffuse brain injuries, affecting large parts of the brain.
- While football is often highlighted, concussions are prevalent across various sports, not just violent ones.
- In football, the rate of concussions is approximately 0.53 per 1,000 athlete exposures.
- Non-contact sports like soccer and basketball also report significant concussion rates, with soccer at 0.28 and basketball at 0.25 per 1,000 athlete exposures.
- A study revealed that 15% of high school athletes involved in contact sports experience at least one concussion per season.
- Effective strategies, such as training in proper techniques and using protective gear, can reduce the risk of concussions across all sports.
2. 👧 High School Sports and Female Soccer Risks
- Female soccer players in American high schools have a significantly higher likelihood of concussions compared to their peers in other sports, highlighting a key area of concern for player safety.
- A major cause of the increased risk is the lack of protective gear in soccer, especially compared to sports like football where helmets are used.
- Headers, a common practice in soccer where players hit the ball with their heads, contribute to the higher incidence of concussions, emphasizing the need for careful monitoring and potential rule adjustments.
- To mitigate risks, schools and sports organizations could implement training programs focused on safe playing techniques and consider rule changes to limit high-risk activities like headers.
- Additionally, research into protective headgear specifically designed for soccer could offer a promising avenue for reducing concussion rates.
3. 🧠 Types of Concussion Injuries Explained
- There are two main types of concussion injuries: coup contra-coup injuries and torque injuries.
- Coup contra-coup injuries involve damage both at the point of impact (coup) and on the opposite side of the brain where it collides with the skull (contra-coup).
- Torque injuries involve rotational forces that cause the brain to twist relative to the brain stem, stretching regions such as the reticular formation, which controls consciousness.
- Damage to the reticular formation can lead to loss of consciousness (blackout).
- Losing consciousness is a significant indicator of a concussion.
- Other red flags of a concussion include having a seizure, increased sleepiness or confusion, worsening headache, persistent vomiting, and sensitivity to light.
4. 🚨 Recognizing and Managing Concussion Symptoms
- For coaches, if there's any concern about a concussion, the rule is 'when in doubt, sit them out.'
- Implementing a protocol where players are evaluated by medical professionals before returning to play can reduce the risk of further injury.
- Educating players and coaches about the symptoms of concussions, such as headaches, dizziness, and confusion, improves early recognition and treatment.
- Establishing a baseline testing program for athletes can help in assessing the impact of a concussion and determining when it's safe to return to play.
