## 4 Discussion  
This study aimed to show the effectiveness of overspeed exercise as a conditioning activity for acute improvement in jump height performance. Moreover, an analysis was extended to consider factors that may be associated with the magnitude of CA effects. The results confirm the potential usefulness of assisted band jumps as a tool for enhancing jumps as a subsequent task. However, differences were observed in time to peak performance, which indicates the need for individualization of rest time. Moreover, analysis of responders and non-responders showed that individual characteristics play a role in the magnitude of change. Practitioners should use a 30% bodyweight reduction in assisted band jump in five repetitions with three sets separated by one minute rest to enhance jump performance, but individual characteristics may affect time to peak performance as well as the magnitude of change. Individuals who possess greater muscular strength, and are more powerful, experienced, and non-asymmetrical individuals are more likely to gain more. Next to high-intensity resistance exercises or isometry, a pyometric-based CA is an effective tool for acute performance enhancement [10; 11; 12; 13; 14]. A study by [PERSON] et al. [45] found that a set of jump exercises induces improvement in subsequent vertical jumps. Another study conducted by [PERSON] and [PERSON] [46] reported that professional rugby union players showed improved performance in CMJ 1-5 min after performing multiple sets of pyometric conditioning activities CA. However, this study only examined the PAPE effects within the first 5 min and found no effects beyond this period, whereas in our study, the performance enhancement was also visible after nine minutes. Conversely, in another study conducted by [PERSON] et al. [47] involving male collegiate soccer players, jump height improvement was observed even 10 min after a pyometric CA. [PERSON] et al. [48] found that pyometric activity is also effective in improving long jump performance. It was shown that one of the important factors for evoking the PAPE effect is a similarity between conditioning activity and subsequent tasks [3; 4]. In these terms, various jumps lead to improvement in subsequent jump tasks due to the use of the same muscle groups and similar patterns of neurological activity [1]. Moreover, the PAPE effect is related to the increase of nervous system activation with joint limitations of muscle energy expenditure  
during pyometric activity [5; 49]. In these terms, assisted band jumps allow for the breaking of the velocity barriers, which leads to higher velocity contraction; therefore, nervous system activity is enhanced. This translates into performance enhancement in subsequent jump tasks [1]. Our study shows some inconsistency in the appearance of peak performance after CA. This was observed in many studies [13]. Despite this, it can be assumed that the general improvement was observed after three minutes post-CA; thus, the time when individuals achieved the best results varied. The meta-analysis by [PERSON] et al. [13] also supports the observation that results improvement is typically seen after a 3-min rest period. Nonetheless, it is important to note that some individuals may require longer rest intervals, up to 6 min, to achieve peak performance. [PERSON] et al. [4] further suggest an optimal rest range of 3 to 7 min for peak performance. However, the variability among individuals regarding peak performance timing is significant, with individual responses to PAPE protocols varying greatly regardless of various factors. In our study, the higher relative strength, measured based on back squat 1 RM with ratio to body mass, contributed the most to a positive response due to the magnitude of change. This is in line with the observations of other authors. [PERSON] et al. [50] showed performance enhancement was linked to the individuals' baseline muscular strength. Stronger ones demonstrated a more pronounced PAPE effect after performing a set of submaximal back squats.
