Abstract
Static stretching (SS) during whole body vibration (WBV) has been suggested for exercise recovery. The purpose was to compare post-exercise self-ratings of fatigue (FAT), mood state (BAM), soreness (SOR), and perceived exertion (RPE) between SS and WBV+SS in swimmers (9 women, mean ± SD: 19.3 ± 1.3 year, 171 ± 5.7 cm, 67.6 ± 7.2 kg, 26.6 ± 4.1 %body fat (%BF); 10 men, mean ± SD: 19.7 ± 1.0 year, 183 ± 5.5 cm, 77.1 ± 4.2 kg, 13.1 ± 2.2 %BF). Athletes were divided by sex, event (sprint, distance), and assigned to SS or WBV+SS. Both conditions consisted of SS performed on the WBV platform with or without WBV (50 Hz, 6 mm). Sessions consisted of: pre and post measures of BAM, FAT, SOR; the condition; and RPE. Mixed factorial ANOVA were run. A significant condition by pre/post interaction was observed (p = 0.035). Post hoc analyses showed WBV+SS elicited lower post-exercise ratings of FAT (p = 0.002) and the BAM affective states, of tension (p = 0.031), and fatigue (p = 0.087). RPE did not differ between conditions. Of interest is the decrease in tension and fatigue noted by the BAM. Mood state can be indicative of how athletes adapt to training volume and intensity.
Highlights
Whole body vibration (WBV) is a mechanical stimulus, which is characterized by oscillatory motion, and is hypothesized to increase neuromuscular stimulation via increased muscle spindle activity and a lowered firing threshold [1,2,3]
The findings demonstrated a significant reduction in two out of six Brief Assessment of Mood (BAM) measures as well as ratings of FAT
A post-exercise WBV+Static stretching (SS) protocol, which consisted of nine, whole-body stretches, was sufficient to reduce self-ratings of fatigue in collegiate swimmers compared to SS without WBV
Summary
Whole body vibration (WBV) is a mechanical stimulus, which is characterized by oscillatory motion, and is hypothesized to increase neuromuscular stimulation via increased muscle spindle activity and a lowered firing threshold [1,2,3]. WBV vibration platforms transfer energy to the human body through intervals of sinusoidal vibrations [2,4]. The intensity of WBV is determined by frequency (rate of oscillation cycles, Hz) and amplitude (displacement or extent of oscillatory motion, mm) [2,4]. Popular with practitioners as a post-exercise recovery modality, the effects of WBV on flexibility, exercise-induced soreness, and fatigue have not been studied extensively
