Resumo
The number of road runners has increased considerably all over the world. Analyzing
variables such as plantar pressure and posture provide important information that
helps to understand several factors related to running performance and prevent
musculoskeletal injuries. The objective of this work was to evaluate, understand and
correct the plantar pressure of beginner runners, through the proposal and application
of training using sensory insoles and biofeedback. The present work was of field
research type, with a longitudinal study with 30 participants. The experimental protocol
was divided into three phases: in the first, the initial assessment of anthropometric data
was carried out, assessment of the biomechanical characteristics of the foot, followed
by static postural assessment using the Kinovea software and, subsequently, the
assessment of static plantar pressure using the platform Pedana Sensor Medica with
FreeStep® software; in the second phase, the participants performed the training
protocol, for 4 weeks, totaling 12 treadmill running interventions and the use of the
ARION® sensory insole with visual biofeedback, for 15 minutes in the first two weeks
and 30 minutes in the last two. In the third phase, the same reassessment as in the
first phase was carried out. Statistical analysis was performed with the SPSS Software
for Windows version 20.0, considering the value of p ≤ 0.05. It was possible to
demonstrate that there was a statistically significant variation between the
measurements of plantar pressure in the forefoot after running training for the variables
surface and surface/load ratio. In the investigation of the forefoot/rearfoot ratio, there
was a significant difference for the surface, load and surface/load ratio variables. There
was a statistical difference in the postural assessment after the protocol with a
reduction in the angles of the head and lower limbs in the anterior view, the head on
the left side in the lateral view and the left ankle and right lower limb in the posterior
view. Experimental results demonstrated that the use of the sensory insole with
biofeedback helps to improve the distribution of plantar pressure and postural angles
of the participants. Therefore, it is possible to infer that the use of this device in new
training methodologies, with a visual interface of the runner's biomechanical
performance, can help reduce injuries and optimize the practice of road running.
