## 6 Discussion
The results of the handball players showed a statistically significant relationship between the SPANT cr test and selected body mass components (\(p<0.05\)). A negative correlation was observed with the body fat percentage in the Elite group (r = \(-0.58\)), in the whole group of female athletes (r = \(-0.37\)), as well as with body weight (kg) and lean body mass (kg). Studies have shown that, the lower the level of body fat, the higher the number of observed and correct answers. This suggests that body fat level may affect correct decision-making during a handball match. A parallel situation took place in the test in PAMT cr with body mass (kg) and fat-free mass (kg) in all the groups. This shows that, the higher the body mass, the fatter, the lower the number of correct responses. Moreover, in HECOR MT test was observed a statistical correlation with body fat percentage in all male groups, as well as a correlation with fat-free mass and total body water (kg) in the Sub-Elite group. Meanwhile, in the group of female handball players, SPANT MT correlated with fat-free mass and total body water. Such conclusions are confirmed by the studies of other researchers. [PERSON] et al. [46] observed that the group of participants with a higher level of BMI had a significantly longer reaction time. Moreover, they noticed significant differences between the reaction time of the mid- and high-BMI groups [46]. Meanwhile, in the research of [PERSON] et al. [50], the authors noticed that lower leg fat percentages and fat mass in takewondo athletes affected the reaction time in a positive way. Moreover, [PERSON] et al. [51], in their research on reaction time and body tissue composition of upper limbs in young female basketball players, found a correlation between movement time and the FFM [kg] (r = \(-0.62\)), as with PMM [kg] (r = \(-0.63\)) parameters. Referring to the results obtained in a group of female and male handball players at the different levels of competition, it should be concluded that even small differences in body mass composition can have a substantial influence on the speed of in-time decision-making on the pitch, anticipation of the opponent's movement and reaction time and movement time during each offensive and defensive action in handball. This scientific study has some limitations that need to be taken into account during its interpretation. The number of male handball players is very similar, but only 60 were tested in the female group, divided into Elite and Sub-Elite groups. We also did not have a balanced number between male and female handball players. A larger sample would have ensured greater consistency and range of results presented. Regarding the female sample size in this study, it is important to note that the relatively small number of female participants could impact the broader applicability of the results. Therefore, future research with a larger and more diverse sample of female participants is necessary to enhance the generalizability of the results and provide more comprehensive insights into the psychomotor abilities, body composition and training experience of female handball players across various levels of competition. The findings of this study on psychomotor abilities, body composition and training experience of Elite and Sub-Elite handball players have several practical implications for handball coaches, particularly in the context of optimizing player performance. For example, this study suggests that body fat percentage, fat-free mass and total body water may influence reaction time, movement time and correct responses. Coaches can use this information to identify players who may benefit from adjustments in their body composition, such as implementing specific conditioning training to reduce body fat or increase lean muscle mass. Elite players, who have accumulated more years of experience, may demonstrate superior reaction time and movement efficiency compared to Sub-Elite players.
