The aim of the present study was to examine the effect of partial sleep deprivation at the end of the night (PSDE) on anaerobic performances during the Wingate test (peak (PP) and mean (MP) power) and the hand grip (HG) test in judokas. In a randomized order, twenty-one judokas (age: 19.1 ± 1.2 yrs; height: 176.5 ± 4.2 cm; body mass: 77.3 ± 6.3 kg) performed two sessions after a normal sleep night (NSN) or a PSDE. During each session, they carried out the Wingate and the HG tests before (T0) and after (T1) a judo match. Rating of perceived exertion (RPE) scores were obtained at the end of the combat. PP and MP decreased significantly from T0 to T1 during the two experimental conditions (p < 0.01), and from NSN to PSDE at T0 and T1 (p < 0.05). However, the HG strength decreased only from T0 to T1 (p < 0.001) and was not significantly affected by PSDE. Likewise, the RPE scores were not affected by PSDE. Therefore, PSDE (i) reduced muscle power during the Wingate test and (ii) did not affect muscle strength during the HG test.
