Abstract Recent public concern over the short- and long-term effects of repetitive head impacts (RHI) associated with purposeful heading in soccer has led researchers to study a multitude of variables related to this important aspect of the game. Of particular interests are the effects of soccer heading in the youth population (≤ 13 years old) whose brains are undergoing rapid development. We conducted a review on youth soccer heading that includes purposeful heading frequency, head impact biomechanics, head injuries, clinical outcomes, and modifying factors. We have concluded that youth soccer players head the ball at a low frequency that typically increases with age and with a finding that boys head the ball more often than girls do. Interestingly, although girls head the ball less frequently than boys do, they tend to sustain higher head impact magnitudes. Head injuries are more likely to occur in girls versus boys and during games because of contact with another player. Clinical outcome measures of concussion are often utilized to study the effects of soccer heading, in both field and laboratory environments. Immediately following soccer heading, youth often report having a headache and demonstrate some deficits in balance measures. Modifying factors that may benefit soccer players participating in purposeful heading activities include stronger neck musculature, wearing headgear, and the use of mouthguards. Research involving youth soccer players needs to be expanded and funded appropriately to better understand the consequences of RHI in both the short and long term.

1 Introduction

Youth soccer heading frequency is influenced by age and sex.

Soccer is the most popular sport in the world with over 260 million participants [1]. In the United States alone, youth soccer has grown from just 100,000 players in 1974 to over 3 million participants today [2]. A unique part of soccer involves purposeful heading in which players may use their heads to advance the ball in play. This skill is typically taught after youth players have learned and practiced the fundamentals of dribbling, passing, and shooting. Like most skills, purposeful heading in soccer takes practice to properly execute and master. Soccer heading, along with tackling in American Football and body checking in ice hockey are examples of sport activities where repetitive head impacts (RHI) can occur. Repetitive head impacts, also known as subconcussive impacts, are “cranial impacts that do not result in a known or diagnosed concussion on clinical grounds” [3]. However, some researchers also include impacts that result in a concussion in the definition of RHI [4]. In earlier literature, it was observed that contact sport athletes, with no diagnosed concussion, compared to controls had deficits in neurocognitive functioning, from which the term ‘subconcussion’ originated [3, 5, 6]. The term “subconcu
