Acute and Cumulative Effects With Whole-Body Vibration Exercises Using 2 Biomechanical Conditions on the Flexibility and Rating of Perceived Exertion in Individuals With Metabolic Syndrome: A Randomized Clinical Trial Pilot Study.

ABSTRACT: This study evaluated the effects of 6 weeks of whole-body vibration (WBV) exercise on flexibility and the rating of perceived exertion (RPE) in metabolic syndrome (MetS) individuals using 2 biomechanical conditions (fixed frequency [FF] and variable frequency [VF]). Nineteen MetS individuals were randomly allocated in FF-WBV (n = 9, 7 women and 2 men) and VF-WBV (n = 10, 8 women and 2 men) groups. Anterior trunk flexion (ATF) and RPE were determined before and after each session. The acute cumulative exposure effects were analyzed. The FF-WBV group was exposed to 5 Hz on a side alternating vibrating platform (SAVP), exposed to 10 and 50 seconds with the SAVP turned off. The VF-WBV group individuals were intermittently exposed (1 minute WBV exercise/1 minute rest) to 5 to 16 Hz, increased by 1 Hz per session and the peak-to-peak displacement (PPD) were 2.5, 5.0, and 7.5 mm. Regarding to ATF, significant improvements (P < .05) were observed in the in the acute (VF group) and cumulative intervention (FF and VF-WBV groups). The RPE significantly (P < .05) improved only in VF-WBV (cumulative intervention). In conclusion, WBV exercise improved the flexibility and decreased the RPE in MetS individuals. These findings suggest that WBV exercise can be incorporated into physical activities for MetS individuals.

Project description:The aim of this study was to investigate the convergent validity of session rating of perceived exertion (s-RPE) with objective measures of internal training load (TL) in professional classical ballet dancers. Heart rate and s-RPE data were collected in 22 professional classical ballet dancers across a total of 218 ballet class or rehearsal sessions. Eleven participants completed at least 9 sessions, and were therefore included in analyses of individual relationships between s-RPE and objective measures. To calculate s-RPE, the session duration was multiplied by the RPE, measured using the modified Borg CR-10 scale. The Edwards summated heart rate zones (Edwards TRIMP) and Banister training impulse (Banister TRIMP) methods were used as criterion measures of internal TL. Pearson product-moment correlation coefficients were used to determine intra-individual relationships between s-RPE and objective measures. Repeated measures correlations were used to identify intra-individual relationships common across the cohort. Positive linear relationships were seen between s-RPE and objective measures across all session types [Edwards TRIMP: r rm (195) = 0.81, p < 0.001; Banister TRIMP: r rm (195) = 0.79, p < 0.001], in ballet class [Edwards TRIMP: r rm (58) = 0.64, p < 0.001; Banister TRIMP: r rm (58) = 0.59, p < 0.001], and in rehearsals [Edwards TRIMP: r rm (119) = 0.82, p < 0.001; Banister TRIMP: r rm (119) = 0.80, p < 0.001], as well as across both males [Edwards TRIMP: r rm (136) = 0.82, p < 0.001; Banister TRIMP: r rm (136) = 0.80, p < 0.001], and females [Edwards TRIMP: r rm (57) = 0.80, p < 0.001; Banister TRIMP: r rm (57) = 0.78, p < 0.001]. Intra-individual correlation coefficients ranged from 0.46-0.96 [Edwards TRIMP: mean r = 0.81 ± 0.11, p = 0.051 - < 0.001; Banister TRIMP: mean r = 0.78 ± 0.14, p = 0.13- < 0.001]. These results demonstrate that s-RPE is a valid and practical method for measuring internal TL in professional classical ballet dancers.

Project description:Purpose The aim of this study was to compare biomechanical swallowing outcomes and perceived effort as well as detraining effects of the established Head Lift Exercise (HLE) and the novel Recline Exercise (RE) in healthy older adults. Method Twenty-two healthy older adults were randomized to perform either the RE or the HLE for a period of 6 weeks. Subjects underwent videofluoroscopic swallowing studies at 3 time points (baseline, postexercise, and following a 6-week detraining period). Primary outcome measures included biomechanical measures of superior and anterior hyoid excursion and upper esophageal sphincter opening, obtained using kinematic analyses on the recorded swallows. Perceived exertion ratings during exercise, as measured by the Borg scale, were included as a secondary outcome measure. Linear mixed-effects models were utilized to compare exercise groups and evaluation time points. Results The 2 exercise groups did not differ significantly in age, body mass index, or body fat percentage at baseline. Significant postexercise increases were seen in superior hyoid excursion, F(2, 36.7) = 24.01, p ≤ .0001, and anterior hyoid excursion, F(2, 36.7) = 5.40, p = .0088, for both exercise groups. Upper esophageal sphincter opening did not increase significantly following the exercise regimens, F(2, 36.5) = 2.14, p = .1322. Both groups displayed a significant decrease in perceived exertion levels over the course of the exercises, F(5, 98) = 23.73, p ≤ .0001. On average, Borg ratings were 20% lower for the RE group than the HLE group at all time points, F(5, 20) = 7.94, p = .0106, indicating that this exercise was perceived as easier to perform. Eighteen participants were followed after detraining, and no differences in detraining effects were seen between groups. In general, gains in biomechanical measures were better maintained on larger bolus types. Conclusions In healthy older adults, the HLE and the RE produced similar gains and detraining effects in biomechanical swallow outcomes. The RE exercise, however, required significantly less effort. These findings suggest that the RE is easier to perform for healthy older adults and thus may be a valuable treatment option for individuals who have difficulty performing the HLE. Further investigation in patients with dysphagia is warranted. Supplemental Material https://doi.org/10.23641/asha.7742897.
