    While there is clear evidence in the literature that the hematological parameters in athletes of different sports are affected by exercise and varying loads, to our knowledge, there are limited studies on the real impact of kickboxing matches on kickboxers' hematological parameters. In this context, this cross-sectional study was conducted to examine the acute changes in the hematological parameters of kickboxers following K1 matches. With the participation of 10 kickboxing K1 athletes, the hematological parameters, including the WBC, Plt, Neut, Lymph, Mono, RBC, Hgb, Hct, CK, La, and glucose levels, were examined before and after matches. Paired sample t-tests were used to compare the pre-test and post-test hematological parameters of the participants. The findings indicated statistically significant differences in the post-match WBC, Plt, Neut, Lymph, CK, La, and glucose levels, while no statistically significant differences were observed in the RBC, Hct, Hgb, and CK levels (p < 0.05). These results not only emphasize the complexity of physiological changes in athletes, but also show consistency with various findings in the literature, while contradicting some. Therefore, it is highlighted that further research is needed to understand the effects of K1 matches on hematological parameters.

    Examining the effects of post-activation performance enhancement on boxers' visual reaction time
    (Stowarzyszenie Idokan Polska-Idokan Poland Assoc, 2024) Ilbak, Ismail; Stojanovic, Stefan; Rydzik, Lukasz; Ambrozy, Tadeusz; Wasacz, Wojciech; Kasicki, Krzysztof; Ilbak, Yunus emre
    Background. There is strong evidence suggesting that Post-Activation Performance Enhancement (PAPE) can acutely enhance various aspects of sports performance, such as strength, endurance, speed, and agility. However, there is a gap in research regarding the effects of PAPE on reaction time performance. Therefore, the aim of this study was to investigate the effects of PAPE on the visual reaction time performances of amateur boxers. Material and Methods. A cross-sectional study was conducted with 17 amateur boxers. Anthropometric measurements were taken, and participants performed a 1-RM Bench Press performance test preceded by 5 minutes of low-intensity running. The PAPE pro- tocol was then administered 72 hours later after another 5 minutes of low-intensity running to avoid fatigue. Visual reaction time was measured immediately before the PAPE protocol and six times at 3-minute intervals afterward. Data were analyzed using IBM Statistics (SPSS, ver. 26.0, Armonk, NY, USA) software. Results. The study found that although there was a difference in the mean visual reaction time performance of participants before and after the PAPE protocol, this difference was not statistically significant (p > 0.05). Therefore, it can be concluded that PAPE does not have an enhancing effect on the visual reaction time performance of boxers. Conclusions. In conclusion, this study suggests that PAPE does not significantly affect visual reaction time performance in amateur boxers. Further research may be warranted to explore other factors that may influence reaction time in this population.
