Dominik Kolinger Title: Immediate effect of posterior chain facilitation using foam rolling on reactive strength performance. Objectives: The main aim of this study is to determine whether the inclination of the trunk towards the vertical changes after foam roller facilitation, whether the magnitude of the jump increases or whether the contact time during reactive force performance is reduced. Methods: In this thesis an experiment in the form of a randomized crossover study was used. Fifteen active female athletes with the problem of physiological maintenance of trunk position during running participated in the measurement. Subjects performed repeated snatch jumps over hurdles 57-68 cm in height. For the skip jumps, we measured jump height and support time using an Optojump (Microgate, Bolzano, Italy) and maximal trunk tilt using a video camera (GoPro HERO 9). After the warm-up, probands completed two measurements (pre-test) within 2 minutes. Then, the intervention group of probands performed foam rolling facilitation - m. triceps surae, mm. hamstrings, m. gluteus maximus, m. erector trunci; for each muscle group for 30 s, with a frequency of 1.5 Hz; the control group had rest...
