Figure 3. Bla, HR, CMJloss, RPE, and AIP with different COD speeds in the 5m and 2.5m distance. Abbreviation: BLa, blood lactate concentration (mmol·L–1); HR, heart rate (bpm); CMJloss, the loss of height of countermovement jumps between pre-test and post-test (cm); RPE, rating of perceived exertion; AUC, area under the receiver operating characteristic curve (AU).
