Running is one of the most popular and accessible sport activities enjoyed by people worldwide. Despite the health benefits, running-related musculoskeletal injuries are common in recreational joggers. These problems are often due to incorrect running technique. The aim of the study was to compare the acute effects of two different video biofeedback interventions on running pattern. Candidates for the intervention were recruited from November 1 to December 29, 2023, and were assigned by randomization to one of the two study groups: sensorized insoles (GS) or video-analysis (GV).
Participants were asked to run in their usual running shoes at self-selected speed. First, they completed an 8-minute warm-up on a non-sensorized treadmill. The biofeedback intervention lasted 6 minutes and the assessments were done before and after the intervention, using a sensorized treadmill. All the steps listed above were separated by a five-minute washout time. For both lower limbs, the spatio-temporal parameters of running indicated by the literature were evaluated. The frequency, length and width of the stride and the flight time improved in both groups but not significantly. There were no significant differences between the groups. The results, although not significant and obtained with a small sample, seem to indicate that both techniques have positive effects and deserve further studies, carried out with an adequate sample and for longer times.
