The purpose of this study was to determine the effectiveness of a program created to improve the blocking performance of a men's university volleyball team. Its effectiveness was verified by comparing the performance of the volleyball team before and after the introduction of the program. We hypothesized that improving the six component elements of body movement in the preparatory phase of blocking would be effective for improving blocking performance. A practice program was thus created to improve the blocking skills of the team. The team members used this practice program six days a week for ten weeks. The numerical values for each component element of two teams—Japan's top team in the V·Premier League and the university team—were compared. The practice program was then created on the basis of these data. The team trained with this program six days a week for ten weeks. The university team consisted of six men: height 187.7±3.4 cm, weight 77.3±6.4 kg, age 19.3±0.5 years and career 9.7±2.6 years. The autumn league games were played after training with the new practice program. Performances in the spring and autumn seasons were compared based on an analysis of the six component elements. The analysis results showed that the six component elements of body movement in the blocking process improved after training with the new practice program. Furthermore, the number of effective blocking performances increased dramatically. Thus, the results of this study show that improving the individual components of the blocking process is effective for improvement of overall blocking performance.
