The effect of plyometric and resistance training on MMP and CoQ10 in tennis players

This study was conducted to investigate the effects of plyometric and resistance training on MMP and CoQ10 in tennis players. A total of 24 tennis players between the ages of 20 and 25 studying at Van Yüzüncü Yıl University were included in the study, including the control group (n=8), plyometric training group (n=8) and resistance training group (n=8). Experimental study model, one of the quantitative research methods, was applied in the study. The levels of MMP 2, MMP 9, TIMP 1, TIMP 2 and CoQ10 analytes were determined in the blood samples taken from the participants. Statistical Package for the Social Sciences (SPSS; IBM Corp, Armonk, NY) version 22 and a seven-day free trial of GraphPad Prism 8 were used for statistical analyses. Data were analyzed at a significance level of p<0.05. When MMP 2, MMP 9, TIMP 1, TIMP 2 and CoQ10 blood results were analyzed, there was a significant difference (p<0.05) between the pre-post test plasma CoQ10 and MMP 9 levels of the resistance group and the plyometric group. This difference was realized as a decrease in serum CoQ10 and MMP 9 levels. There was no difference between the groups (p>0.05). TIMP 2 level was significant in the resistance training group compared to the control and plyometric training groups (p=0.019) and the serum TIMP 2 level of the resistance training group was in a decreasing trend compared to the other two groups. The between-group difference in serum CoQ10 level between the resistance training group compared to the control and plyometric training group was significant (p=0.017) and the serum CoQ10 level of the resistance training group had a decreasing trend compared to the other two groups. There was no significant difference in the comparisons of other analytes between groups and between measurement times (p>0.05).In conclusion; resistance training and plyometric training had a positive effect on MMP 2, MMP 9, TIMP 1, TIMP 2 and CoQ10 parameters. In conclusion, it was determined that resistance training and plyometric training provided a positive result on MMP 2, MMP 9, TIMP 1, TIMP 2 and CoQ10 parameters. However, further longitudinal studies are needed by increasing the sample size. Keywords: tennis, plyometric, resistance, mmp, tımp, coq10
