The hysterical force, or super strength, or superhuman strength, is a demonstration of extreme strength, hypothetically outside human capacity, that is, beyond what is usually interpreted in the context of normality; in general, such manifestations occur in precarious situations between "life or death".
There are quite common anecdotal examples, such as those of certain mothers who have moved real vehicles to save their child stuck in the rubble.
The causes that support these manifestations are not clear, but it is hypothesized that they may be of a hormonal nature. To be precise, the implication of catecholamines should not be excluded; in practice, the hysterical force could be the cause of an uncontrolled discharge of adrenaline. Unfortunately, such situations are not repeatable, rather rare and use little evidence. Assuming that it is possible, the deepening of these phenomena is almost impossible.
It cannot be excluded that the expression of superhuman strength can be realized following the so-called "delirium of excitement".
