Seventeen male\n                    amateur soccer players (24.0\u00b11.8 y) completed three different preconditioning\n                    sessions before the Yo\u2013Yo Intermittent Recovery Test Level 2. The ischemic\n                    preconditioning protocol consisted of three cycles of 4-minute occlusion (220 mm\n                    Hg), followed by 4-minute reperfusion (0 mm Hg) in both thighs (at rest). Active\n                    protocols were similar to ischemic preconditioning; however, during reperfusion,\n                    participants performed intermittent running (ischemic preconditioning+Yo\u2013Yo\n                    Intermittent Recovery Test Level 2) or three-repetition maximum squat\n                    repetitions (ischemic preconditioning+SQUAT). We assessed countermovement jump\n                    and Yo\u2013Yo Intermittent Recovery Test Level 2 performance, heart rate, muscle\n                    oxygen saturation, blood lactate, rating of perceived exertion, and\n                    session-rating of perceived exertion. Ischemic preconditioning+SQUAT resulted in\n                    a greater Yo\u2013Yo Intermittent Recovery Test Level 2 distance compared to ischemic\n                    preconditioning (p=0.02 and effect size=0.3) and ischemic\n                    preconditioning+YOYO (p=0.01, effect size=0.2). Countermovement jump\n                    performance was affected by condition (p&lt;0.01), with ischemic\n                    preconditioning+YOYO presenting higher values compared with ischemic\n                    preconditioning (effect size=1.1), although no time effect was observed. No\n                    significant differences were observed for muscle oxygen saturation\n                    (p=0.09), blood lactate (p=0.32), and rating of perceived\n                    exertion\/session-rating of perceived exertion (p=0.96); however, the mean\n                    heart rate was higher with active reperfusion conditions than ischemic\n                    preconditioning. Active reperfusion combined with heavy squat exercise slightly\n                    improved high-intensity intermittent running performance in soccer players,\n                    while also eliciting higher heart rate responses, which should be considered\n                    during training monitoring.<\/jats:p>","DOI":"10.1055\/a-2934-8226","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T23:23:22Z","timestamp":1787268202000},"source":"Crossref","is-referenced-by-count":0,"title":["Active
