Effect of Whole-body Vibration on the Ankle Joint, Plantar Pressure, and Running Paramethers

The main purpose of this study was the assessment of whole-body vibration warm-up, modified drop jumps, and combination of both on the range of motion of dorsiflexion in the ankle joint and running time. 16 recreationally active runners performed 4 different warm-up variants one week apart: 5 sets of 30 s calf raises on the platform but without vibration (CTRL), the same as CTRL group but with vibration with 30 s rest intervals between sets (WBV), 6 drop jumps with a 30 s rest interval between sets (DJ); last group was combination of both WBV and DJ groups (WBV+DJ). The study included muscle flexibility tests for the soleus and gastrocnemius muscles performed before the warm-up, 3 minutes after warm-up and immediately after a 3000 m run on a treadmill. The running time was measured and the run had to be completed in the shortest possible time.

Additionally, in the third week of the study there were performed static and dynamic foot measurements immediately before and after a 3000 m treadmill run. The main purpose of that gait analysis was to assess the impact of a 3km run on plantar pressure patterns and gait parameters in recreational runners.

Primary outcomes

  1. Ankle dorsiflexion range of motion (Gastrocnemius muscle flexibility test)

    Time frame: 3 times - before the warm-up, 3 minutes after warm-up and immediately after a 3000 m run

    The participant laid in a supine position with his knee straight and his ankle joint off the table. The researcher 1 tested the maximum dorsiflexion of the foot and controlled the position of the knee. The researcher 2 applied the AMI digital inclinometer (OPIW, Poland) to the outer edge of the foot. The The angle of dorsiflexion was measured in degrees.

  2. Ankle dorsiflexion range of motion (Soleus muscle flexibility test)

    Time frame: 3 times - before the warm-up, 3 minutes after warm-up and immediately after a 3000 m run

    The participant laid in a supine position with the knee bent 90 degrees. The researcher 1 performed passive maximum dorsiflexion of the foot. The researcher 2 applied the AMI digital inclinometer (OPIW, Poland) to the outer edge of the foot. The angle of dorsiflexion was measured in degrees.

  3. Static foot analysis (FootScan platform)

    Time frame: 2 times - immediately before and after 3000 m run

    In static measurement participants stood barefoot on the Footscan platform at a designated point, assuming a relaxed and natural position, remaining still and looking straight ahead with their arms by their sides. Static paramethers include the pressure of the parts of each foot (impulse - Ns/cm).

  4. Dynamic foot analysis (FootScan platform) 1

    Time frame: 2 times - immediately before and after 3000 m run

    During dynamic measurement participants were asked to walk barefoot in a relaxed manner at a self-selected comfort speed, and not to look at the ground. Dynamic parametrers include foot pressure (impulse - Ns/cm).

  5. Dynamic foot analysis (FootScan platform) 2

    Time frame: 2 times - immediately before and after 3000 m run

    During dynamic measurement participants were asked to walk barefoot in a relaxed manner at a self-selected comfort speed, and not to look at the ground. Dynamic parametrers include gait speed (m/s).

  6. Dynamic foot analysis (FootScan platform) 3

    Time frame: 2 times - immediately before and after 3000 m run

    During dynamic measurement participants were asked to walk barefoot in a relaxed manner at a self-selected comfort speed, and not to look at the ground. Dynamic parametrers include walking time (s).
