Abstract

Relationship between Herat frequency and performance in throwing precision in waterpolo”. Purpose: To evaluate if the throwing precision from 4 meters at different heart rate intensities (180, 150 and 120) is altered and to what magnitude the effective loss in the throw to goal. Methodology: 12 waterpolo players from the Costa Rica’s national team, with 4 years of international experience. A waterpolo net (“sniper”) was used to assess throwing precision. Each player had 5 opportunities in each heart rate frequency and the number of successful shots was accounted for in percentages. This procedure was repeated in three different days. A one way ANOVA with repeated measures was done and a Post Hoc Tukey analysis to determine the statistical significant differences . Results: The statistical analysis indicated a significant difference between the three levels of throw that were tested. A continuous increase in precision as the heart rate decreased. Discussion: To go from (120 to 150) the precision decreased 20,53%, unlike when it passed from (150 to 180) there was a decreased from 33,94%. This results point out the importance of performing training where the throw with precision to the goal must be performed at intense heart pulsations and always close to the most possible real situation of match
