Countermovement-jump (CMJ) height, serum concentration of creatine kinase (CK), delayed-onset muscle soreness (DOMS), and perceived recovery and stress (Short Recovery and Stress Scale) were measured 24 h before and 24 h after the training program.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>\n                      <jats:italic>Results:<\/jats:italic>\n                    <\/jats:title>\n                    <jats:p>\n                      The HIT shock microcycle induced a large decrease in CMJ performance (ACT: effect size [ES] = \u20131.39,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05; PAS: ES = \u20131.42,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05) and perceived recovery (ACT: ES = \u20131.79,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05; PAS: ES = \u20132.39,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05), as well as a moderate to large increase in CK levels (ACT: ES = 0.76,\n                      <jats:italic>P<\/jats:italic>\n                      &gt; .05; PAS: ES = 0.81,\n                      <jats:italic>P<\/jats:italic>\n                      &gt;.05), DOMS (ACT: ES = 2.02,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05; PAS: ES = 2.17,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05), and perceived stress (ACT: ES = 1.98,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05; PAS: ES = 3.06,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05), compared with the values before the intervention.
