| Summary: | Abstract Background Technique and tactics are key elements in assessing table tennis performance and have been widely studied. However, most existing methods classify shots solely by sequence or shot number, overlooking the tactical attributes and their impact on rally outcomes. The First Offensive Shot (FOS) model attempted to address this issue but remained too coarse-grained. To overcome these limitations, this study introduces the Enhanced FOS model (EFOS), which integrates shot type and shot number into a more refined state-transition framework. This novel approach provides a more detailed representation of rally dynamics, enabling a deeper analysis of rally progression. Methods The EFOS model divides a rally into three phases: the pre-offensive phase (POP), the initial-offensive phase (IOP), and the final-offensive phase (FOP). Each phase is further categorised based on shot type and shot number. Transition probabilities between states were computed. A comprehensive analysis was conducted on 105 men’s and women’s singles matches from the Olympic Games Tokyo 2020, with gender, ranking, and match results as independent variables. Results The IOP accounts for the highest usage (70.6%) among the three phases, with FOS and the following shot–FOS + 1–rank second. Male players tend to use defensive techniques to return shots and attack later, whereas female players prefer to attack defensive shots directly. High-ranked players (≤ 40) demonstrated superior transition efficiency and lower error rates, particularly in the IOP, while winners consistently exhibited higher transition rates and fewer errors across all phases. Conclusions Firstly, the initial-offensive phase emerges as pivotal, with the first offensive shot and the subsequent shot significantly influencing rally outcomes. Secondly, attacking defensive shots have proven to be more effective than attacking serves. Thirdly, male players outperform female players in both initial and subsequent attack. These findings offer practical insights for players and coaches, suggesting that training should emphasise the initial-offensive phase and focus on reducing errors during transitions, particularly for low-ranked players. Additionally, gender-specific training strategies may be developed to address the observed performance differences. |
