In this work we investigate the consequences of running gravitationalcoupling on the properties of rotating black holes. Apart from the changesinduced in the space-time structure of such black holes, we also study theimplications to Penrose process and geodetic precession. We are motivated bythe functional form of gravitational coupling previously investigated in thecontext of infra-red limit of asymptotic safe gravity theory. In this approach,the involvement of a new parameter $\tilde{\xi}$ in this solution makes itdifferent from Schwarzschild black hole. The Killing horizon, event horizon andsingularity of the computed metric is then discussed. It is noticed that theergosphere is increased as $\tilde{\xi}$ increases. Considering the black holesolution in equatorial plane, the geodesics of particles, both null and timelike cases, are explored. The effective potential is computed and graphicallyanalyzed for different values of parameter $\tilde{\xi}$. The energy extractionfrom black hole is investigated via Penrose process. For the same values ofspin parameter, the numerical results suggest that the efficiency of Penroseprocess is greater in quantum corrected gravity than in Kerr Black Hole. At theend, a brief discussion on Lense-Thirring frequency is also done.
