Quantifying head impacts is a vital component to understanding and preventing head trauma in sport. Our objective was to establish the frequency and magnitude of head impact mechanisms in men's lacrosse athletes. Eleven male lacrosse athletes wore xPatch sensors during activity. Video footage of practices and games was analyzed to verify impacts and code them with impact mechanisms. We calculated incidence rates (IR) per 1000 exposures with corresponding 95% confidence intervals (CIs) and used MANOVAs to compare the linear (g) and rotational (rad/sec2) accelerations between mechanisms. A total of 167 head impacts were successfully verified and coded with a mechanism using video footage during 542 total exposures. The highest incidence rate was head to body (IR=118.08, 95% CI=89.15-147.01) and the lowest was head to ball (IR=3.69, 95% CI=0-8.80; IRR=32.00 (95% CI=67.83-130.73). Analysis indicated that impact mechanism failed to significantly alter the combined dependent variables (multivariate F10,306=1.79, P=.06, η2= .06, 1-β=.83). While head to head, body to head, and stick to head mechanisms are penalty-inducing offenses in men's lacrosse, head to ground, head to ball, and combination impacts have similar head accelerations. If penalties and rules are created to protect players from traumatic head injury, we recommend stricter enforcement.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 January 2019.
All research outputs
#24,100,909
of 34,376,207 outputs
Outputs from Journal of Applied Biomechanics
#655
of 912 outputs
Outputs of similar age
#259,299
of 388,367 outputs
Outputs of similar age from Journal of Applied Biomechanics
#16
of 17 outputs
Altmetric has tracked 34,376,207 research outputs across all sources so far. This one is in the 28th percentile – i.e., 28% of other outputs scored the same or lower than it.
So far Altmetric has tracked 912 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one is in the 25th percentile – i.e., 25% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 388,367 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one is in the 5th percentile – i.e., 5% of its contemporaries scored the same or lower than it.
