"Head acceleration" refers to how fast your head is moving or speeding up in a certain direction. It is a measure of the change in velocity of your head and can happen during activities like sports or accidents. It is important to be cautious of
head accelerations as they can cause injuries.

A
high head acceleration occurred when the dummy's head hit the steering wheel through the airbag, indicating that head injuries would be possible.
A high
head acceleration occurred when the dummy's head hit the steering wheel through the airbag, indicating that injuries to the head would be possible.
In particular, they could go beyond relatively simple models that focused on just one or two parameters, such as the maximum
head acceleration during an impact.
Several sets of 10 repetitions in each direction, every day, will
decrease head acceleration that is a leading cause of concussion.
The second potential clinical benefit of impact monitoring systems stems not from the idea of monitoring impacts for the presence of an acute injury - generating hit, but from the potential advantage of accurately cataloguing the number of hits and
post-impact head acceleration being experienced by an athlete over time.
These authors further concluded that species which regularly encounter higher
angular head accelerations during locomotion require more orthogonal canals in order to have more uniform sensitivity to angular accelerations in three dimensions.
Data from the sensors were transmitted wirelessly to a computer on the sideline and processed to measure both the linear and
rotational head acceleration resulting from each impact.
The object of the study was to identify specific football drills that result in high - magnitude head impacts (measured
as head accelerations greater than 40g).
Forces recorded on the driver dummy indicate that an injury to the lower right leg would be possible, and a high
head acceleration occurred when the dummy's head bottomed out the airbag.
Kutcher also sees a second a second potential clinical benefit of impact monitoring systems, one which «stems not from the idea of monitoring impacts for the presence of an acute injury - generating hit, but from the potential advantage of accurately cataloguing the number of hits and
post-impact head acceleration being experienced by an athlete over time.»
The magnitudes of these impacts were determined on the basis of linear (g's) and rotational (radians per square second)
head acceleration measured by the HIT System ™, which the authors report as means and 50th and 95th percentiles.
Inside each youth's football helmet was an accelerometer array that recorded
all head accelerations associated with head impacts and sent this information to a nearby computer.
Inside each athlete's helmet was a Head Impact Telemetry (HIT) System ™, which measures
head acceleration.
Head accelerations from the roof rail and B - pillar hits were low.
Head acceleration from the B - pillar hit was low in the first test.
Head acceleration from the B - pillar hit was low.
Head acceleration from the roof rail hit was low.
Head acceleration from this hit was negligible.
Head acceleration from this hit was high.
Head acceleration from the instrument panel hit is low, as is the risk of significant injuries to other body regions.
Head acceleration from the grab handle contact was low.
Head acceleration from the B - pillar / roof rail contact was low.
Head accelerations from the roof contacts were low.
A high
head acceleration and high neck forces occurred when the dummy's head hit the steering wheel through the airbag, indicating that injuries to the head and neck would be likely.
Head acceleration from the roof / sunvisor hit was low.
Head accelerations from the steering wheel and B - pillar hits were low.
Head accelerations from the roof rail, grab handle, and B - pillar hits were low.
Although the dummy's head did hit the pillar between the doors and the roof rail,
head accelerations were low.
Head accelerations from the roof rail, B - pillar, and grab handle hits were negligible.
This caused a high
head acceleration.
The resulting
head acceleration was high.
«We recorded a high
head acceleration when the driver dummy's head hit the steering wheel through the frontal airbag,» Lund explains.
Smeared greasepaint indicates where the dummy's head hit the B - pillar during rebound, producing a high
head acceleration.
Head acceleration from the grab handle hit was low.
Head acceleration from the roof rail / B - pillar hit was low.
Head acceleration from the B - pillar / roof rail hit was low.
