# Acute Effects of Kickboxing K1 Matches on Hematological Parameters of Kickboxers

## TL;DR

This study examines how kickboxing K1 matches affect blood-related parameters in athletes, finding significant changes in several indicators after matches.

## Contribution

The study provides new insights into the acute effects of K1 kickboxing matches on hematological parameters in athletes.

## Key findings

- Significant increases in WBC, Plt, Neut, Lymph, CK, La, and glucose levels were observed after matches.
- No significant changes were found in RBC, Hct, and Hgb levels following matches.
- Results highlight the need for further research on the physiological effects of K1 kickboxing.

## Abstract

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.
