Popis: INTRODUCTION: After anterior cruciate ligament reconstruction surgery, returning the knee to previous levels of strength and function is challenging, with the failure to do so associated with an increased risk of re-injury and long-term degenerative problems. Blood flow restriction (BFR) is gaining popularity as a rehabilitation technique, however its effects on the mechanics of these exercises have not been fully explored. In this study we aimed to determine the acute effects of BFR on the performance of a step-up exercise protocol, and to assess the acceptability of the technique. METHODS: Twenty individuals (12 female / 8 male, mean age 30.6 years), who had recently undergone anterior cruciate ligament reconstruction and 20 controls (11 female / 9 male, mean age 28.0 years) performed a step-up exercise protocol with and without BFR. Lower limb kinematics and kinetics were measured and compared between groups and conditions. Testing was completed in June 2019. RESULTS: Participants in both groups had increased external rotation of the tibia of 2° (p
