The aims of this research are to record and analyze the goals scored during the 64 matches in the 21st World Cup in Russia in 2018, to highlight those factors that are directly related to the teams' effectiveness in scoring, to record the goals approved after the use of new technologies, video assistant referee and goal line technology, as well as their effect on the outcome of the game. Chi-square and univariate general linear methods were used for the data analysis. Statistical difference is observed in the number of goals scored between the two halves (X²=8.699, p<0.005). A comparable percentage of scoring in most of the periods with the exceptions of the periods in overtime, the period from the 16th to 30th min, the additional time of the first and second half and the period from the 76th to 90th min of the game was determined (p<0.01). The teams that scored first won 71.4% matches, lost 9.5% and had a tie 19% of the matches (X²=42.000, p<0.001). Most of the goals were scored following a corner kick (24), penalty (22) and free kick scored non-directly (16), which were significantly different from free kick scored directly (6) and throw in (2) (X²=26.857, p<0.001). 19 goals were scored from cross, 19 from a long-range shot (8 of them with the "inner foot"), 18 from a forward pass and 12 from cutback. Statistical differences between the first four groups and all of the others are determined (X²=27.818, p<0.01). Significant differences were found between the goals that "began" from the offensive third, the middle and the defensive third (X²=73.645, p<0.001). 58.9% of the goals are scored following positional play, which is significantly different compared to the counterattack (29.5%) and direct play (11.6%) (X²=32.611, p<0.001). Over 59 goals were scored from "the inner part of the foot" or "place", and 31 from header, which were significantly different from the other types of shots (X²=89.254, p<0.001).

Purpose. combining resistance and in-water training is a common practice in water polo. The purpose of this study was to examine the acute effects of different external loads during resistance training on the repeated sprint ability in water polo players. Methods. A total of 9 national level water polo players (age: 21.5 ± 2.0 years) executed, on different occasions, a repeated sprint swimming test (8 × 25 m with a 30-s rest) following a low load (50% of 1-repetition maximum) or a high load (80% of 1-repetition maximum) resistance training that consisted of leg press and bench press exercises. During the control condition, the players only performed the repeated ability test. Indices of repeated sprint ability included the best 25-m time (best), the mean time (mean), and the heart rate after the 4 th and the 8 th 25-m effort. In addition, the performance decrement was calculated. Results. control and low load intensity conditions resulted in significantly faster best times than high load intensity (p < 0.01 and 0.05, respectively). Mean times were significantly faster during the control compared with the high load intensity condition (p < 0.05). Performance decrement and heart rate after the 4 th and the 8 th 25-m effort showed no differences between all 3 conditions (p > 0.05). Conclusions. These results suggest that when scheduling intrasession resistance and in-water training in water polo, low load programs should be preferred when the primary goal is the enhancement of repeated swimming performance.
