The main objective of the paper was to evaluate the influence of warm up and the rest interval separating it from exercise on maximal anaerobic power and acid-base balance (ABB). The research material included 12 students of physical education with an average age, maximal oxygen uptake, body height and mass The students performed 3 exercise trials. During trial I a 30s Wingate test was preceded by a 15 min warm-up performed on a ergocycle with the intensity set at 50% VO2max and the pedaling frequency equal to 60 rev./min. The rest interval between the end of warm-up and the onset of exercise equaled 5 min. During the second trial the same warm-up procedure was conducted yet the rest interval between the cessation of warm-up and exercise equaled 15 min. On the third occasion the 30 s Wingate test was performed without a warm-up. During the Wingate test the following variables were registered: total external work (WTOT ),maximal power (Pmax), average power (PAV), time of reaching Pmax (TrPmax) the index of power decrement (Pdi%). Additionally the following acid –base variables were evaluated in the blood: LA, HCO3, BE and pH. The results of ANOVA did not show a significant effect of the 15 min warm-up on all the considered anaerobic power indices: WTOT, Pmax, PAV, TrPmax, while statistically significant effects of the warm-up were obtained in post exercise plasma LA concentration and other acid-base balance variables (p<0,001, F=13,06), HCO3 (p<0,001, F= 14,61), pH (p<0,01, F= 11,49), BE (p<0,001, F= 14,97)...
