Training effect of repeated rolling motions on boccia players with severe cerebral palsy: comparison with the effect of conventional upper-limb training using a crossover test.

[Purpose] The present study aimed to establish evidence regarding comparisons between training methods for boccia players with severe cerebral palsy. [Participants and Methods] Ten boccia players with severe cerebral palsy were enrolled in this study. This intervention had a cross-over design.

Throwing distance and competitive performance of Boccia players.

[Purpose] This study aimed to clarify the relationship between throwing distance and competitive performance in Boccia players in order to establish a training program based on this evidence. [Participants and Methods] In total, 40 athletes, who competed in the Japan Boccia Championships and are certified players of the Japan Boccia Association, participated in the study. Participants threw the Boccia ball as far as possible, and throwing distances were compared between certified players (Group I, n=8), those who participated in the final round (Group II, n=9), and those who lost in the preliminary round (Group III, n=23).
