Effects of a 3-week foam rolling warm-up intervention on ankle dorsiflexion measurements and jumping performance in young rhythmic gymnasts

BACKGROUND: Few studies have analyzed the medium- to long-term effects of warm-up protocols on biomechanical and performance parameters in athletes. This study evaluated the effects of a 3-week foam rolling (FR) protocol integrated into the initial phase of the warm-up on ankle dorsiflexion parameters and jumping performance through the countermovement jump test (CMJ) in young rhythmic gymnasts. METHODS: Twenty-six female young rhythmic gymnasts who met the inclusion criteria participated in the study and were divided into the FR group (n = 12; Age = 13.2 ± 2.59 years; Height = 152.3 ± 13.34 cm; Weight = 39.9 ± 11.22 kg) or the C (Control) group (n = 14; Age = 13.4 ± 2.17 years; Height = 149.5 ± 13.33 cm; Weight = 40.6 ± 10.14 kg). An initial evaluation (T0) and an evaluation after the 3-week FR warm-up protocol were conducted. An inertial sensor was used to analyze ankle dorsiflexion using the following parameters: range of motion (ROM) (°), angular velocity (°/s), and fluency index (0-1). An optical detection sensor detected the jump height and flight time of the CMJ test. RESULTS: = .288) were found. Specifically, significant enhancements in CMJ performance (p < 0.001) and angular dorsiflexion velocity of the right ankle (p < 0.05) were noted after the intervention in the FR group. CONCLUSIONS: Our results suggest that a 3-week FR intervention incorporated into the warm-up routine of young rhythmic gymnasts led to an increase in jump performance, but not in ankle dorsiflexion ROM parameters. Further studies are necessary to investigate the effects of warm-up on biomechanical parameters using longer FR protocols. TRIAL REGISTRATION: NCT07113249. Registration date: 02/08/2025.
