## 4 Discussion
The different methodology can justify many of the differences that appear in the research results. However, they all conclude that using a RW schedule can limit the decline in speed test performance compared to passive rest. In the jumps in the present study, a significant decline in performance was observed after passive rest. More specifically, in CMJ, the performance decreased by 13.2%, while in SJ, it decreased by 8.9%. It should be mentioned here that in the RW condition, decreases in both CMJ (7.3%) and SJ (5.2%) were also observed. In addition to the partial eta square indicator, we find a large main effect between the conditions for CMJ (\(\eta^{2}\) = 0.575) and a largemain effect on passive rest for SJ (\(\eta^{2}\) = 0.539). In a previous study, [PERSON] et al. (2015) [16] reported a decline in CMJ performance smaller than that observed in the present study (7.6% for the control group and 3.1% for the RW group). A decrease in CMJ performance after passive rest is also reported by [PERSON] et al. (2013) [28], while [PERSON] et al. (2013) [19] reported an increase in the flight-time-to-contraction -time ratio after RW. In a recent study, [PERSON] et al. (2020) [30] observed better jumping performance after applying RW. However, the studies that have been applied to soccer players and have measured the change in jumping performance after RW are very limited. All of them report that RW reduced the performance decrement or improved it. Unfortunately, the different methodologies do not allow a comparison of the results. The decrease in body temperature is associated with a decrease in the performance of sprints and jumps [31]. Therefore, the drop in body temperature observed after both passive rest and RW may be the reason for the decrease in performance observed in the jumps. We can assume that the performance decreased less after RW program because the drop in body temperature was less. In the Illinois agility test, the reduction in the soccer players' performance was similar for both conditions (3 min RW: 1%; P (15 min): 1.4%) without being statistically significant. From the review of the literature, we find that there is only one other study that used an agility test (the Arrowhead agility test) in the evaluation of performance after RW [27]. In that study, as in the present one, the RW program they implemented did not limit the decline in performance. Unfortunately, there are no other studies that used the same agility test to be able to make comparisons and draw more secure conclusions because the RW program had no effect. It should be mentioned here that the Illinois test applied in the present study is 60 m, while the Arrowhead test is approximately 35 m. The distances are too different to make any comparisons. One of the aims of the study was to investigate the effect of the same RW program in the first 15 min of the second half. For this purpose, a comparison was made between the internal and external load indicators in the first 15 min of each half. From the results, it appeared that the HR differed both between the conditions and between the halves. In the present study, the soccer players showed a higher HR both in the first 15 min of the first half and also in the second half. Studies that evaluated the change in HR in soccer matches after RW are very few. [PERSON] et al. (2014) [16] observed that in the second half, soccer players started with a higher HR and approached the half-time average faster than the control group. The researchers hypothesized that in the RW group, aerobic metabolism was activated more quickly, limiting the contribution of anaerobic metabolism to the onset of the second half. In a recent study, [PERSON] et al. (2022) [27] observed in a match simulation exercise that, after RW, soccer players in the first seven minutes of the second half showed less HR than the control group.
