Analysis of the physical demands placed on football referees during competitive matches
The aim of this study was to examine the procedural knowledge level in young volleyball players and to establish the relationship between procedural knowledge, experiencie and performance, being the performance the championship positions obtained at the end of the competition. Participants in the study were 110 male young players of the regional teams that disputed the Spain Champioship in Cáceres in june of 2005, and with 1 to 6 years of volleyball experience. The variables of this study were proceedural knowledge, experience in organised volleyball, experience in unorganised volleyball and performance (championship position). Procedural knowledge was measured by the volleyball players by means of “volleyball procedural knowledge test” (Moreno, 2006). The results revealed the lineal and significative relationship between procedural knowledge, experience in organised volleyball and performance, indicating that high-procedural knowledge and experience in organised volleyball exhibited high-championship position. Regression analysis indicated that experience in organised volleyball and procedural knowledge were the main predictor of performance. These findings are discussed with previous researchs.
