One of the tasks for Bulgaria before the second tournament of the Nations League is to improve serve effectiveness. The serve is the only element in volleyball that depends entirely on the performer and is not influenced by the opponent's actions. That is why it is the most suitable component for targeted work between tournaments.
Bulgaria's serving performance
| Match | Serving errors | Effectiveness | Sets | Effectiveness per set |
|---|---|---|---|---|
| Belgium - Bulgaria | 29 | -22% | 4 | -5.50% |
| Bulgaria - Iran | 20 | -21% | 3 | -7.00% |
| Bulgaria - Argentina | 19 | -11% | 4 | -2.75% |
| Bulgaria - Serbia | 16 | -18% | 3 | -6.00% |
Editor's note: "effectiveness per set" is a custom-calculated indicator for comparison between matches of different durations, because such an indicator does not officially exist in volleyball statistics.
| Player | Aces | Errors | Attempts | Success % |
|---|---|---|---|---|
| Asparuhov | 4 | 15 | 56 | 7.14% |
| Nikolov | 4 | 16 | 59 | 6.78% |
| S. Nikolov | 2 | 17 | 50 | 4.00% |
| I. Petkov | 2 | 12 | 33 | 6.06% |
| Atanasov | 2 | 14 | 53 | 3.77% |
| P. Petkov | 1 | 1 | 8 | 12.50% |
| Velichkov | 0 | 1 | 21 | 0.00% |
| Grozdanov | 0 | 5 | 54 | 0.00% |
| Bardarov | 0 | 2 | 3 | 0.00% |
| Palev | 0 | 0 | 4 | 0.00% |
| Antov | 0 | 1 | 2 | 0.00% |
Bulgaria recorded its best performance against Argentina, where 19 service errors were made, and efficiency reached -11% (-2.75% per set). The weakest values were against Belgium (-22%) and Iran (-7.00% per set). The data shows that reducing errors does not automatically lead to better efficiency, which suggests that before the second tournament, Bulgaria should work not only on limiting errors but also on the quality and impact of successful serves.
The numbers themselves do not provide an answer as to whether the reason is excessive aggressiveness, lack of concentration, or technical inaccuracies. However, they clearly show that the serve is the element over which the national team has the most control and, accordingly, the greatest potential for improvement before the next week of the tournament.
