Purpose: to investigate the dynamics of indicators of power endurance of sambists of 14-15 years old under the influence of the offered complexes of exercises by the method «Tabata». Material and Methods. The following methods were used in the research: theoretical analysis and generalization of literary sources; pedagogical observation; pedagogical experiment; pedagogical testing; methods of mathematical statistics. Two groups of sambo wrestlers took part in the research: experimental and control, each of which consisted of 10 sportsmen aged 14-15 years. Pedagogical testing was used to identify the dynamics of physical indicators. Parents of all athletes gave written consent to participate in the pedagogical experiment. Results: the results of pedagogical experiment testify to the improvement of indicators in both groups, however the increase in the experimental group considerably exceeds indicators of the control group on all tests. Statistical check by means of Student's t-test showed that in all tests changes in the experimental group are statistically significant (p<0,01 or p<0,001), while in sportsmen of the control group in many cases the increase of indicators is significantly insignificant. Thus, in the test «Throws of a partner in 1 minute (front footboard)» the increase in indicators of the experimental group amounted to 40,3 %, and the value of t=5,9 (p<0,001) confirms a significant increase in power endurance. In the test «Turns on a throw over a back with an elastic expander for 1 minute» the increase of indicators of the experimental group made 43,5 %, a value t=6,02 (p<0,001) testifies to statistical reliability of this increase. In the test «Throws of a mannequin over a hip for 1 minute», the increase of sportsmen of the experimental group made 29 %, at a value t=5,1 (p<0,001) that indicates a statistically significant result. In the test «Flexion and extension of arms in a lying support» in sportsmen of the experimental group the increase made 55,4 %, and value t=5,13 (p<0,001) confirms significant changes. In the test «Raising of a trunk in a sitting position for 1 minute» indicators of the experimental group by 24,3 %, value t=5,16 (p<0,001) testifies to statistically significant changes. In the test «Pulling up on a crossbar»indicators of the experimental group increased (43,4 %), at t=6,34 (p<0,001) that is statistically significant. In the «Burpees in 30 seconds» test, the increase in the average value of the experimental group increased by 32,8 %, at t=5,06 (p<0,001), which indicates a statistically significant increase. The obtained data confirm the efficiency and advantage of complexes of exercises by the method «Tabata» in the development of power endurance of sambists, improvement of general physical fitness of sambists. Conclusions. It is established that the offered complexes of exercises by the method «Tabata» considerably increase power endurance in the performance of turns with resistance, at the performance of technical techniques that is important for sambo and increases the level of special physical fitness. Also, the offered complexes of exercises improve power endurance of muscles of a back, arms and a trunk, increases the level of the general physical fitness.
