For this reason, nowadays that there are two defensive players specialized within the position of LIBEROS, it is common for coaches to find some players who are wired to pass on serve-receive and find other liberos who can dig hard-driven balls better than passing a floater serve. The matter of fact is that utilizing the underhand pass in serve receive is both physiologically and neuromechanically different than utilizing it in a defense situation. Notice that when volleyball was introduced to Asia countries, many top defenders acquired the habit to keep their eyes on the ball even during the time that players are touching the ball. Intuitively, players developed a lower stance that chose to contact the ball at the waistline or the level of their thighs because it was developmentally appropriate and more efficient (suitable) for them.Īnother adaptation that happened naturally, was that at the time of contact players would project their eyes to the target. Therefore, we understand that the evolution of the underhand forearm pass happened as a natural adaptation to the game. Therefore, there was (and there has always been) a hardware issue related to why the underhand forearm became so useful in the game of volleyball. Human development psychology explains that it is perfectly normal for some children in this stage to be shortsighted. In some cases, participants at that age also demonstrated some difficulties to play hard-driven balls geared towards their faces. 25 (250 milliseconds or 25 msecs) human speed of reaction threshold.Īnother reason why it is so important to use the underhand forearm pass deals with the notion that many people who first played volleyball were children under the age of 10. However, when the players waited to contact the ball below their waistline or even at the level of their thighs, it would be considerably easier to play the ball because the contact would happen after. The standing position and the use of their hands were always a movement that conflicted with physiological reactions such as leaning their bodies backward and/or closing their eyes when the ball was too fast that a player could not process most likely because of the speed of the ball was faster than the players' speed of reaction. Very early, in the development of volleyball, participants were urged to protect themselves against very fast balls served or attacked at them by their opponents. The startle reflex or Moro reflex happens as a reaction to an abrupt noise or movement, including a movement of other objects thrown at a person's eyes. The fast-driven ball at the players' faces always created body reactions linked to children’s startle reflex trigged by the eyes. The development and evolution of the underhand pass happened as a result of a necessity and/or as a self-protection mechanism. ![]() When volleyball was created, very quickly players learned how to adapt to the fast shots and spikes coming from the opponent side. Many volleyball players might ask this important question.
