The main outcomes were PTmax (maximal PT, muscle contractility), MPmax (maximal metabolic power exercise intensity) and PTdec (PT decline, muscle fatigability) obtained during intermittent runs of increasing intensity with multiple changes of direction interspersed with electrically evoked contractions. Relative total and sprint distances covered during a whole match and during short intervals were quantified from a sub-sample.<\/p>\n<p><strong>Results<\/strong>: PTmax and MPmax were higher for first than for second division (p &lt; 0.047; d = 0.15-0.23) and Under-19 players (p &lt; 0.007; d = 0.17-0.25). MPmax was lower (p &lt; 0.016; d = 0.23-0.32) and PTdec was higher (p &lt; 0.004; d = 0.26-0.39) in the pre-season compared to all the other time points. MPmax was higher for fullbacks than attackers and defenders (p &lt; 0.041; d = 0.20-0.22). PTdec was higher for defenders than fullbacks, midfielders and wings (p &lt; 0.029; d = 0.21-0.28). PTmax was associated with whole-match relative total distance (p = 0.004; d = 0.26). PTdec was associated with whole-match relative total distance and relative short-interval sprint distance (p &lt; 0.050; d = 0.18-0.22).<\/p>\n<p><strong>Conclusion<\/strong>: The ability to sustain repeated change of direction efforts at high intensities while preserving peripheral muscle function should be considered an important determinant of soccer physical performance.<\/p>\n<p>Eur J Appl Physiol.\u00a02022 Jun 29.
