Introduction: Following a running session, alterations may take place in how the nervous system receives, processes, and utilizes information to regulate movements [1]. Knowing how skin sensitivity, plantar pressure, and stability change in response to exercise can help coaches and physical therapists to better plan post-exercise recovery.
Aim: To determine whether a 5 km treadmill run affects foot sensitivity, plantar pressure distribution, and postural control in recreational runners.
Materials & Methods: Eleven male runners (35 ± 15 yrs) were submitted to assessment of plantar sensitivity (monofilaments), plantar pressure (baropodometry), and postural control (center of pressure on baropodometer). Assessments were conducted before, immediately after, and at 15 and 30 minutes following a 5 km running session (60% of maximum heart rate [2]) on a treadmill.
Results: Running on the treadmill increased midfoot sensitivity and plantar pressure as well as contact area in the forefoot region, with effects that lasted up to 15 min after the exercise. The displacement of the center of pressure revealed greater body oscillations up to 30 minutes after the exercise.
Summary: A 5 km run can acutely alter both sensory afferent parameters and biomechanical parameters related to postural control and plantar pressure. The choice of exercises after a running session must consider an acute negative effect on the postural control capacity in recreational runners.
