Abstract

Purpose: To quantify the peak post-pitch-entry physical responses of soccer substitutes while assessing contextual influences. Peak responses may be important performance indicators for substitutes introduced to provide a physical impact. Method: Thirty-three professional substitutes wore Microelect...

Peak responses may be important performance indicators for substitutes introduced to provide a physical impact. Method: Thirty-three professional substitutes wore Microelectromechanical Systems during 44 matches (4 &#xB1; 3 observations&#xB7;player&#x2212;1). Post-pitch-entry relative peak values for total and high-speed (&gt; 5.5 m&#xB7;s&#x2212;1) distances, average acceleration, and PlayerLoad&#x2122; were calculated using rolling averages over 60-s to 600-s. Linear mixed models assessed contextual influences (position, substitution timing, scoreline, and location). Results: Substitutes introduced during the final ~15 min of match-play covered less high-speed distance than first-half substitutes (~2.8&#x2013;3.1 m&#xB7;min&#x2212;1) over 480-s to 600-s epochs, and less than 60:00&#x2013;74:59 min substitutes (~1.7&#x2013;1.8 m&#xB7;min&#x2212;1) during 540-s and 600-s epochs. Average acceleration during all except 180-s epochs was lower for 75:00+ min substitutes compared with first-half replacements (~0.27&#x2013;0.43 m&#xB7;s&#x2212;2), and lower than 60:00&#x2013;74:59 min substitutes during 60-s (~0.13 m&#xB7;s&#x2212;2). Substitutes introduced when their team was winning recorded greater distances over 120-s to 600-s (~6.2&#x2013;7.7 m&#xB7;min&#x2212;1), and higher PlayerLoad&#x2122; values during 120-s, 180-s, 300-s, and 480-s epochs (~2.7&#x2013;3.6 arbitrary units&#xB7;min&#x2212;1), compared with when scores were level at pitch-entry. Irrespective of substitution timing, substitute midfielders exceeded the total distance of substitute attackers (~5.9&#x2013;16.2 m&#xB7;min&#x2212;1) for all except 360-s and 600-s epochs, and defenders (~13.3&#x2013;26.7 m&#xB7;min&#x2212;1) during epochs &lt; 300-s. Conclusions: This study provides benchmark data for practitioners tailoring training and recovery protocols, particularly &#x201C;top-up&#x201D; conditioning, to the competitive demands of soccer substitutes.
