A short and graphical article on the impact of concussions in contact sports. The HealthWorks Collective article unfortunately only focuses on concussion when there’s mounting evidence that cumulative sub-concussive blows at 15-20Gs are just as harmful as concussions at 100Gs [TTA 5 June] and a cause of CTE (chronic traumatic encephalopathy). Hard hits in US football can go up to a stunning 150Gs.The main article is from Popular Mechanics which also describes how equipment, including shoulder pads, are being designed to distribute and detect impact. What’s also surprising is how many Gs normal activities such as hopping off a (high?) step (8.1G) and sneezing (2.9G) can be.
