The paper you linked was about professional boxers. I am not an expert on boxing or kinesiology, but I have to think that receiving a punch from a professional boxer would be a lot worse than receiving one from the average college guy.
Thanks. I responded to a comment which counterfactually disputed the claim of memory loss resulting from concussion. Citing sources derived from accepted canon, I noted how memory loss is actually common to concussions.
The Japanese study was included to illustrate how a single punch could concuss. It was confined to boxers, so there is no evaluation of punches or punch effects delivered or received by non-boxers.
However,
Google is replete with accounts of fatalities (typical of subdural hematomas) resulting from a single punch administered by non-boxers.. It seems to [follow] any single-punch capable of killing an individual could surely trigger "memory loss."
In fact, the paper describes "jarring" vs. "non-jarring" punches and notes that the former is rather specific to boxing (p. 348). "Jarring punches were variously described as a punch that moves the head laterally (38.7%), a punch that turns the head (58.5%), and unknown (12%)." This is the type that is more often associated with memory loss ...
WRT "jarring" and "non-jarring", I believe you've misapprehended the text on 2 levels.
Text: "There is a 'jarring' punch, which only boxers who have experienced this type of punch can know, as well as a 'non-jarring'. When asked to describe 'jarring', boxers gave the following answers: cloudy head and wobbly legs (76.2%), fatigue (4.6%), mentally weakened (27%), weakened legs (8.5%), and temporary loss of memory or consciousness (5.7%)."
You: "In fact, the paper describes 'jarring' vs. 'non-jarring' punches and notes that the former is rather specific to boxing."
1. No, the text describes the ability of
respondents, i.e., boxers, to discriminate "jarring" from "non-jarring." The study does
not imply, state or suggest non-boxers cannot, do not or are not capable of delivering or receiving punches which meet the criteria for "jarring." (Cf.
Google, one-punch)
2. According to the text, respondents did not confine "jarring" to hooks alone. Respondents simply noted punches which turned the head, e.g. hooks (58.5%), were the most common source of jarring while other punches comprised a smaller though significant percentage (38.7%, 12%). Shorter: Any punch can produce a "jarring" effect; among boxers, hooks were more "common" than others.
The point is that we don't know the physics of the punch CR took, so we have to be careful estimating its effects.
Indeed. I've suggested nothing about the type of punch CR allegedly absorbed. I've merely noted single punches can produce concussions, how memory loss is common to & symptomatic of same.
