The purpose of this study was to determine the impact of fatigue on the results of pinalty kicks on futsal players. This study uses the Pre-Experimental method in a one-group pretest-posttest design, one group is measured or observed not only after being exposed to a type of treatment, but also before. The population used in this study were 12 members of the women's futsal club Futsal 35 who already had 2-3 years of experience. The instrument used in this study was the R.A.S.T Test 6 x 35m. Running-based Anaerobic Sprint (RAST) and lactic acid measuring instrument. The results of data processing and analysis showed the lactate value of 12 people before fatigue with a value of 17.67 mmol / l, and the lactate value after fatigue amounted to 127.75 mmol / l. However, the results have been tested using the RAST test. However, the results that have been tested using the paired sample t test can be explained that there is no difference in the results of penalty kicks against the results with a P value (0.027) > 0.05. This shows that there is no significant effect of the impact of fatigue on the results of penalty kicks in futsal players.
