The main aim of this study was to examine the mediating effect of the change of direction speed (CODs) on reactive agility (RA) in female players participating in different team sports (TS). In total, there were 31 elite female players from the Polish national basketball (n = 12, aged 24.98 ± 3.38) and handball (n = 19, aged 27.34 ± 4.68) teams participated in this study. Two experiments using the ‘five-time shuttle run to gates’ test with similar movement patterns were used to determine the players’ RA and CODs. A simple mediation model was utilised to investigate the potential mediation role of CODs and its effect on RA. The results revealed a primary, statistically significant effect of TS on RA (B = 0.796, p = 0.005), which decreased and became statistically insignificant after including the CODs variable into the model of mediation analysis (B = 0.337, p = 0.192). The RA test results were mediated by changes in CODs (B = 0.764, p < 0.001). Likewise, TS affected CODs (B = 0.602, p = 0.016). The general conclusion is that the relationship between TS and RA is not inherent. The direct effect of TS on RA disappears in the presence of the mediator CODs. Study results confirm the relevance of using the mediation analysis to apply in sport training. Identification of the critical ingredients of the athletes’ agility performance can improve training programs by focusing on effective components.

Key words: Competitive sport, motor performance, performance analysis

           Key Points
  • The three-variable parallel analysis used in the study indicates that the relationship between type of sports and reactive agility is not inherent in professional team game players.
  • The direct effect of the type of sport on the reactive agility disappears in the presence of the mediator change of direction speed.
  • The sport-specific change of direction technique can be the basis for more complex agility tasks in team sports.
