Because many athletes perform both MI and SS as part of their warm-up routine before a performance event, it is important to understand their effectiveness. Currently, the effects of MI have shown positive benefits, whereas SS has demonstrated negative effects in young healthy individuals. However, these modalities have not been compared with each other in terms of anaerobic performance, specifically power. Therefore, the purpose of this study is to compare the effects of MI and SS on anaerobic performance in trained cyclists. We hypothesized that MI would increase anaerobic performance, whereas SS would cause it to decrease as measured by the Wingate anaerobic power test in young, trained cyclists.
