Effects of Whole-Body Vibration on Heart Rate Variability During Post-Exercise Recovery (WBV-HRV)
Effects of Whole-Body Vibration Versus Passive Recovery on Frequency-Domain Heart Rate Variability Following High-Intensity Exercise: A Randomized Crossover Trial
This study aims to investigate the acute effects of whole-body vibration (WBV) and passive recovery on heart rate variability (HRV) following high-intensity intermittent exercise in male soccer players.
Ten male soccer players will participate in a randomized, two-period crossover study. Each participant will complete two experimental sessions separated by a seven-day washout period. During each session, participants will perform the Yo-Yo Intermittent Recovery Test Level 1 until exhaustion, followed by either 15 minutes of seated whole-body vibration or 15 minutes of seated passive recovery.
During the WBV condition, participants will remain seated with their knees flexed at approximately 90 degrees and their bare feet positioned on a vibration platform operating at 35 Hz with a peak-to-peak amplitude of 2 mm. During passive recovery, participants will remain seated without vibration.
Heart rate variability will be continuously recorded throughout the exercise test and the entire 15-minute recovery period using a chest-strap heart rate sensor. Frequency-domain HRV parameters, including very-low-frequency (VLF), low-frequency (LF), and high-frequency (HF) power, will be analyzed.
The study will compare the autonomic responses associated with the two recovery methods to determine whether seated whole-body vibration produces different short-term HRV responses compared with passive recovery.

Descrição detalhada
This study is designed as a randomized, two-period crossover trial to examine the acute effects of whole-body vibration (WBV) and passive recovery on frequency-domain heart rate variability (HRV) following exhaustive intermittent exercise.
Ten male soccer players will participate in the study. Participants will be randomly assigned to one of two intervention sequences: WBV followed by passive recovery (AB) or passive recovery followed by WBV (BA). A seven-day washout period will separate the experimental sessions to minimize potential carryover effects.
At each experimental session, participants will complete the Yo-Yo Intermittent Recovery Test Level 1 until voluntary exhaustion. Following exercise, participants will undergo a 15-minute recovery intervention according to their assigned sequence.
During the WBV intervention, participants will sit on a chair with their knees flexed at approximately 90 degrees and their bare feet placed on a vertical vibration platform operating at 35 Hz with a peak-to-peak displacement of 2 mm. During the passive recovery intervention, participants will remain seated in a comparable position with their feet resting on the floor and without vibration exposure.
Heart rate variability will be recorded continuously throughout the exercise test and the complete 15-minute recovery period using a Polar H10 chest-strap sensor. HRV data will be processed using Kubios HRV software to obtain frequency-domain parameters, including VLF, LF, and HF power.
The primary objective is to compare frequency-domain HRV responses between WBV and passive recovery conditions. Statistical analyses will account for the paired crossover design and evaluate differences between recovery conditions.
The findings are expected to contribute to the understanding of acute autonomic responses to whole-body vibration as a post-exercise recovery intervention in soccer players.

Experimental: Sequence AB (WBV → Passive Recovery)
Participants assigned to Sequence AB will undergo whole-body vibration (WBV) recovery during the first experimental period, followed by passive recovery during the second period. A seven-day washout period will separate the two sessions. Both recovery interventions will last 15 minutes and will be performed in a seated position following the Yo-Yo Intermittent Recovery Test Level 1. During WBV recovery, participants will remain seated with their feet placed on the vibration platform, operating at 35 Hz and 2 mm peak-to-peak amplitude. |
Participants assigned to the whole-body vibration (WBV) intervention will undergo a 15-minute recovery session immediately following the Yo-Yo Intermittent Recovery Test Level 1. During the intervention, participants will remain seated on a chair with their knees flexed at approximately 90 degrees and their bare feet placed on a vertical vibration platform. The platform will operate at a frequency of 35 Hz and a peak-to-peak amplitude of 2 mm. Heart rate variability will be continuously recorded throughout the 15-minute recovery period to evaluate autonomic nervous system responses. Participants assigned to the passive recovery intervention will undergo a 15-minute seated recovery session immediately following the Yo-Yo Intermittent Recovery Test Level 1. During this period, participants will remain seated on a chair with their feet resting on the floor, without receiving whole-body vibration or any other active recovery intervention. Heart rate variability will be continuously recorded throughout the 15-minute recovery period to evaluate autonomic nervous system responses. |
