The relationship between impact force, neck strength, and neurocognitive performance in soccer heading in adolescent females.
Head impacts are common in contact sports , but only recently has there been a rising awareness of the effects of subconcussive impacts in adolescent athletes . A better underst and ing of how to attenuate head impacts is needed and therefore , this study investigated the relationship between neck strength , impact , and neurocognitive function in an acute bout of soccer heading in a sample of female high school varsity soccer players . Seventeen participants completed the ImPACT neurocognitive test and had their isometric neck strength tested ( flexion , extension , and bilateral flexion ) before heading drills . Each participant was outfitted with custom headgear with timing switches and a three-dimensional accelerometer affixed to the back of the head , which allowed for measurement of impact during heading . Participants performed a series of 15 directional headers , including 5 forward , 5 left and 5 right headers in a r and om order , then completed the ImPACT test again . Neurocognitive tests revealed no significant changes following heading . However , there were statistically significant , moderate , negative correlations ( r = -0.500:-0.757 , p < .05 ) between neck strength and result ant header acceleration , indicating that those with weaker necks sustained greater impacts . This suggests neck strengthening may be an important component of any head injury prevention/reduction program
