We analyze the problem facing the team that wins the toss at the deciding fifth set of a volleyball match. The team’s decision to serve or to receive the service can make a difference to the eventual outcome of the match. We characterize the conditions under which it is better to serve or to receive the service at that set. These conditions are obtained by first expressing the exact probability...

This paper aimed at comparing expert and novice volleyball players in a visuomotor task using realistic stimuli. Videos of a volleyball setter performing offensive action were presented to participants, while their eye movements were recorded by a head-mounted video based eye tracker. Participants were asked to foresee the direction (forward or backward) of the setter's toss by pressing one of ...

Countermovement jumps loaded with a weighted vest are often used for the training of lower body power to improve jump performance. However, it is currently unknown how this added load affects the lower extremity kinematics and kinetics, in particular whether this results in an increased injury risk. Therefore, the purpose of this investigation was to determine how lower extremity kinematics and...

The purpose of this study was to determine and to compare characteristics of the lower limb extension musculature in Chilean indoor and beach volleyball players and the muscular contribution during the CMJ. The sample was composed by 13 subjects belonging to the Chilean elite beach and indoor volleyball. The subjects performed 3 CMJ jumps for average determination of the height of the jump, ecc...
