    Gauges measured stress on the metacarpals during punches and slaps on padded-dumbbell targets created with a pendulum-like device.

    I take “a pendulum-like device” to mean they suspended either the arms or the targets and swung them to a collision.

      This whole device sounds morbid but hilarious. Did they like strap dead bodies to a swing and position them like Superman and swing their bodies into a wall fist fist?

        That would have been awesome, but I suspect that it was just the arms and that it was powered in some way, hence “pendulum-like”.
