A group of resistance-trained eumenorrheic women (n = 9) were tested in three phases over the menstrual cycle: bleeding phase, follicular phase, and luteal phase (i.e., days 1–3, 7–10, and 19–21 of the cycle, respectively). Each testing phase consisted of a battery of jumping tests (i.e., squat jump [SJ], countermovement jump [CMJ], drop jump from a 30 cm box [DJ30], and the reactive strength index) and 30 m sprint running test. Two different applications for smartphone (My Jump 2 and My Sprint) were used to record the jumping and sprinting trials, respectively, at high speed (240 fps). The repeated measures ANOVA reported no significant differences (p ≥ 0.05, ES < 0.25) in CMJ, DJ30, reactive strength index and sprint times between the different phases of the menstrual cycle. A greater SJ height performance was observed during the follicular phase compared to the bleeding phase (p = 0.033, ES = −0.22). No differences (p ≥ 0.05, ES < 0.45) were found in the CMJ and sprint force-velocity profile over the different phases of the menstrual cycle. Vertical jump, sprint performance and the force-velocity profiling remain constant in trained women, regardless of the phase of the menstrual cycle. metadata García-Pinillos, Felipe; Bujalance-Moreno, Pascual; Lago-Fuentes, Carlos; Ruiz-Alias, Santiago A.; Domínguez-Azpíroz, Irma; Mecías-Calvo, Marcos y Ramirez-Campillo, Rodrigo mail SIN ESPECIFICAR, SIN ESPECIFICAR, carlos.lago@uneatlantico.es, SIN ESPECIFICAR, SIN ESPECIFICAR, marcos.mecias@uneatlantico.es, SIN ESPECIFICAR (2021) Effects of the Menstrual Cycle on Jumping, Sprinting and Force-Velocity Profiling in Resistance-Trained Women: A Preliminary Study.
