long duration measurements of Whole Body Vibration exposures associated with surface coal mining equipment compared to previous short duration measurements
2016Co-Authors: Robin Burgesslimerick, Daniellie LynasAbstract:ABSTRACTPrevious measurements of Whole-Body Vibration associated with earth-moving equipment at surface coal mines have highlighted the significance of the hazard. Considerable variability in measurement amplitudes, even within the same equipment type operated at the same site, has been noted. However, the measurements have previously been undertaken for relatively short durations. Fifty-nine measurements were collected from a range of earth-moving equipment in operation at a surface coal mine. Measurement durations ranged from 100–460 min (median = 340 min). The results indicate that the measurements previously observed are not an artifact of the relatively short durations and confirm that operators of dozers and off-road haul trucks, in particular, are frequently exposed to vertical Whole-Body Vibration levels which lie within, or above, the Health Guidance Caution Zone defined by ISO2631.1. Further investigations are justified to identify opportunities for reducing operators' exposure to high amplitude...

an ios application for evaluating Whole Body Vibration within a workplace risk management process
2015Co-Authors: James Mcglothlin, Robin Burgesslimerick, Danellie LynasAbstract:Workplace management of Whole-Body Vibration exposure requires systematic collection of Whole-Body Vibration data in conjunction with the numerous variables which influence Vibration amplitudes. The cost and complexity of commercially available measurement devices is an impediment to the routine collection of such data by workplaces. An iOS application (WBV) has been developed which allows an iPod Touch to be used to measure Whole-Body Vibration exposures. The utility of the application was demonstrated by simultaneously obtaining 98 pairs of Whole-Body Vibration measurements from both the iPod Touch application and a commercially available Whole-Body Vibration device during the operation of a variety of vehicles and mobile plant in operation at a surface coal mine. The iOS application installed on a fifth-generation iPod Touch was shown to provide a 95% confidence of +/− 0.077 m/s2 r.m.s. constant error for the vertical direction. Situations in which Vibration levels lay within the ISO2631.1 health guida...

can an ipod touch be used to assess Whole Body Vibration associated with mining equipment
2014Co-Authors: Rebecca Wolfgang, Luke Di Corleto, Robin BurgesslimerickAbstract:The cost and complexity of commercially available Whole-Body Vibration measurement devices is a barrier to the systematic collection of the information required to manage this hazard. The potential for a consumer electronic device to be used to estimate Whole-Body Vibration was assessed by collecting 58 simultaneous pairs of acceleration measurements in three dimensions from a fifth-generation iPod Touch and gold standard Whole-Body Vibration measurement devices, while a range of heavy mining equipment was operated at three surface coal mines. The results suggest that accelerometer data gathered from a consumer electronic device are able to be used to measure Whole-Body Vibration amplitude with 95% confidence of ±0.06 m s(-2) root mean square for the vertical direction (1.96 × standard deviation of the constant error).

Whole Body Vibration exposure of haul truck drivers at a surface coal mine
2014Co-Authors: Rebecca Wolfgang, Robin BurgesslimerickAbstract:Abstract Haul truck drivers at surface mines are exposed to Whole-Body Vibration for extended periods. Thirty-two Whole-Body Vibration measurements were gathered from haul trucks under a range of normal operating conditions. Measurements taken from 30 of the 32 trucks fell within the health guidance caution zone defined by ISO2631-1 for an 8 h daily exposure suggesting, according to ISO2631-1, that “caution with respect to potential health risks is indicated”. Maintained roadways were associated with substantially lower Vibration amplitudes. Larger trucks were associated with lower Vibration levels than small trucks. The descriptive nature of the research, and small sample size, prevents any strong conclusion regarding causal links. Further investigation of the variables associated with elevated Vibration levels is justified. Relevance to industry The operators of mining equipment such as haul trucks are exposed to Whole-Body Vibration amplitudes which have potential to lead to long term health effects. Systematic Whole-Body Vibration measurements taken at frequent intervals are required to provide an understanding of the causes of elevated Vibration levels and hence determine appropriate control measures.

2010Co-Authors: Tom Broekmans, Geert Alders, Machteld Roelants, Peter Feys, Herbert Thijs, Bert O. EijndeAbstract:Objective To investigate the acute effects of long-term Whole-Body Vibration on leg muscle performance and functional capacity in persons with multiple sclerosis. Design A randomized controlled trial. Subjects Twenty-five patients with multiple sclerosis (mean age 47.9 ± 1.9 years; Expanded Disability Status Scale 4.3 ± 0.2) were assigned randomly to Whole-Body Vibration training (n = 11) or to a control group (n = 14). Methods The Whole-Body Vibration group performed static and dynamic leg squats and lunges on a Vibration platform (25-45 Hz, 2.5 mm amplitude) during a 20-week training period (5 training sessions per 2-week cycle), and the control group maintained their usual lifestyle. PRE-, MID- (10 weeks) and POST- (20 weeks) knee-muscle maximal isometric and dynamic strength, strength endurance and speed of movement were measured using isokinetic dynamometry. Function was determined through the Berg Balance Scale, Timed Up and Go, Two-minute Walk Test and the Timed 25-Foot Walk Test. Results Leg muscle performance and functional capacity were not altered following 10 or 20 weeks of Whole-Body Vibration. Conclusion Under the conditions of the present study, the applied 20-week Whole-Body Vibration exercise protocol did not improve leg muscle performance or functional capacity in mild- to moderately impaired persons with multiple sclerosis during and immediately after the training programme.

Whole Body Vibration induced increase in leg muscle activity during different squat exercises
2006Co-Authors: Machteld Roelants, Sabine Verschueren, Oron Levin, Christophe Delecluse, Valere StijnenAbstract:Roelants, M,, S,M,P, Verschueren, C, Delecluse, O, Levin, and V. Stijnen, Whole-Body-Vibration—induced increase in leg muscle activity during different squat exercises, J. Strength Cond. Res. 20(l):124-129. 2006,—This study analyzed leg mus- cle activity during Whole-Body Vibration (WBV) training. Sub- jects performed standard unloaded isometric exercises on a vi- brating platform (Power Plate): high squat (HS), low squat (LS), and 1-legged squat (OL), Muscle activity of the rectus femoris, vastus lateralis, vastus medialis, and gastrocnemius was record- ed in 15 men (age 21,2 ± 0,8 years) through use of surface elec- tromyography (EMG), The exercises were performed in 2 con- ditions: with WBV and without (control (CO)) a vibratory stim- ulus of 35 Hz, Muscle activation during WBV was compared with CO and with muscle activation during isolated maximal volun- tary contractions (MVCs), Whole-Body Vibration resulted in a significantly higher (p < 0,05) EMG root-mean-square compared with CO in all muscle groups and all exercises (between -1-39,9 ± 17,5% and +360,6 ± 57,5%), The increase in muscle activity caused by WBV was significantly higher (p < 0,05) in OL com- pared with HS and LS, In conclusion, WBV resulted in an in- creased activation of the leg muscles. During WBV, leg muscle activity varied between 12,6 and 82,4% of MVC values.

Effects of Whole Body Vibration training on muscle strength and sprint performance in sprint-trained athletes
2005Co-Authors: Christophe Delecluse, R. Diels, Machteld Roelants, Erwin Koninckx, Sabine M.p. VerschuerenAbstract:Despite the expanding use of Whole Body Vibration training among athletes, it is not known whether adding Whole Body Vibration training to the conventional training of sprint-trained athletes will improve speed-strength performance. Twenty experienced sprint-trained athletes (13 male symbol, 7 female symbol, 17-30 years old) were randomly assigned to a Whole Body Vibration group (n=10: 6 male symbol and 4 female symbol) or a Control group (n=10: 7 male symbol, 3 female symbol). During a 5-week experimental period all subjects continued their conventional training program, but the subjects of the Whole Body Vibration group additionally performed three times weekly a Whole Body Vibration training prior to their conventional training program. The Whole Body Vibration program consisted of unloaded static and dynamic leg exercises on a Vibration platform (35-40 Hz, 1.7-2.5 mm, Power Plate). Pre and post isometric and dynamic (100 degrees/s) knee-extensor and -flexor strength and knee-extension velocity at fixed resistances were measured by means of a motor-driven dynamometer (Rev 9000, Technogym). Vertical jump performance was measured by means of a contact mat. Force-time characteristics of the start action were assessed using a load cell mounted on each starting block. Sprint running velocity was recorded by means of a laser system. Isometric and dynamic knee-extensor and knee-flexor strength were unaffected (p>0.05) in the Whole Body Vibration group and the Control group. As well, knee-extension velocity remained unchanged (p>0.05). The duration of the start action, the resulting start velocity, start acceleration, and sprint running velocity did not change (>0.05) in either group. In conclusion, this specific Whole Body Vibration protocol of 5 weeks had no surplus value upon the conventional training program to improve speed-strength performance in sprint-trained athletes.

Effects of 24 Weeks of Whole Body Vibration Training on Body Composition and Muscle Strength in Untrained Females
2004Co-Authors: Machteld Roelants, Christophe Delecluse, Maaike Goris, Sabine M.p. VerschuerenAbstract:The aim of this study was to investigate and to compare the effect of 24 weeks "Whole Body Vibration" training and fitness training on Body composition and on muscle strength. Forty-eight untrained females (21.3 +/- 2.0 yr) participated in the study. The Whole Body Vibration group (N = 18) performed unloaded static and dynamic exercises on a Vibration platform (35 - 40 Hz, 2.5 - 5.0 mm; Power Plate). The fitness group (N = 18) followed a standard cardiovascular (15 - 40 min) and resistance training program including dynamic leg press and leg extension exercises (20 - 8 RM). Both groups trained 3 times weekly. The control group (N = 12) did not participate in any training. Body composition was determined by means of underwater weighing. Additionally 12 skinfolds were assessed. Isometric (0 degrees /s) and isokinetic (50 degrees /s, 100 degrees /s, 150 degrees /s) knee-extensor strength was measured by means of a motor-driven dynamometer (Technogym). Over 24 weeks there were no significant changes (p > 0.05) in weight, in percentage Body fat, nor in skinfold thickness in any of the groups. Fat free mass increased significantly in the Whole Body Vibration group (+ 2.2 %) only. A significant strength gain was recorded in the Whole Body Vibration group (24.4 +/- 5.1 %; 5.9 +/- 2.1 %; 8.3 +/- 4.4 %; 7.6 +/- 1.5 %) and in the fitness group (16.5 +/- 1.7 %; 12.0 +/- 2.7 %; 10.4 +/- 2.3 %; 10.2 +/- 1.9 %), at 0 degrees /s, 50 degrees /s, 100 degrees /s and 150 degrees /s respectively. In conclusion, 24 weeks Whole Body Vibration training did not reduce weight, total Body fat or subcutaneous fat in previously untrained females. However, Whole Body Vibration training induces a gain in knee-extensor strength combined with a small increase in fat free mass. The gain in strength is comparable to the strength increase following a standard fitness training program consisting of cardiovascular and resistance training.

effects of Whole Body Vibration training on postural control in older individuals a 1 year randomized controlled trial
2007Co-Authors: An Bogaerts, Sabine Verschueren, Christophe Delecluse, Albrecht Claessens, Steven BoonenAbstract:This randomized controlled trial investigated the effects of a 12 month Whole Body Vibration training program on postural control in healthy older adults. Two hundred and twenty people were randomly assigned to a Whole Body Vibration group (n = 94), a fitness group (n = 60) or a control group (n = 66). TheWhole Body Vibration and fitness groups trained three times a week for 1 year. TheVibration group performed exercises on a Vibration platform and the fitness group performed cardiovascular, strength, balance and stretching exercises. Balance was measured using dynamic computerized posturography at baseline and after 6 and 12 months. Whole Body Vibration training was associated with reduced falls frequency on a moving platform when vision was disturbed and improvements in the response to toes down rotations at the ankle induced by the moving platform. The fitness group showed reduced falls frequency on the moving surfacewhen vision was disturbed. Thus, Whole Body Vibration training may improve some aspects of postural control in community dwelling older individuals.

strength increase after Whole Body Vibration compared with resistance training
2003Co-Authors: Christophe Delecluse, Machteld Roelants, Sabine VerschuerenAbstract:DELECLUSE, C., M. ROELANTS, and S. VERSCHUEREN. Strength Increase after Whole-Body Vibration Compared with Resistance Training. Med. Sci. Sports Exerc., Vol. 35, No. 6, pp. 1033–1041, 2003. Purpose: The aim of this study was to investigate and to compare the effect of a 12-wk period of Whole-Body Vibration training and resistance training on human knee-extensor strength. Methods: Sixty-seven untrained females (21.4 1.8 yr) participated in the study. The Whole-Body Vibration group (WBV, N 18) and the placebo group (PL, N 19) performed static and dynamic knee-extensor exercises on a Vibration platform. The acceleration of the Vibration platform was between 2.28 g and 5.09 g, whereas only 0.4 g for the PL condition. Vibration (35– 40 Hz) resulted in increased EMG activity, but the EMG signal remained unchanged in the PL condition. The resistance-training group (RES, N 18) trained knee extensors by dynamic leg-press and leg-extension exercises (10 –20 RM). All training groups exercised 3 wk 1 . The control group (CO, N 12) did not participate in any training. Pre- and postisometric, dynamic, and ballistic knee-extensor strength were measured by means of a motor-driven dynamometer. Explosive strength was determined by means of a counter-movement jump. Results: Isometric and dynamic knee-extensor strength increased significantly (P 0.001) in both the WBV group (16.6 10.8%; 9.0 3.2%) and the RES group (14.4 5.3%; 7.0 6.2%), respectively, whereas the PL and CO group showed no significant (P 0.05) increase. Counter-movement jump height enhanced significantly (P 0.001) in the WBV group (7.6 4.3%) only. There was no effect of any of the interventions on maximal speed of movement, as measured by means of ballistic tests. Conclusions: WBV, and the reflexive muscle contraction it provokes, has the potential to induce strength gain in knee extensors of previously untrained females to the same extent as resistance training at moderate intensity. It was clearly shown that strength increases after WBV training are not attributable to a placebo effect. Key Words: MUSCLE STRENGTH, TONIC Vibration REFLEX, COUNTER-MOVEMENT JUMP, STRENGTH TRAINING
