The current study examined the effects of using an unstable surface during whole-body vibration (WBV) exercise on leg and trunk muscle activity during a static semi-squat. Twenty-eight recreationally active university students completed 4 different test conditions: 1) stable surface with no WBV; 2) unstable surface with no WBV; 3) unstable surface with 30 Hz WBV low amplitude; and 4) unstable surface with 50 Hz WBV low amplitude. Surface electromyography (sEMG) was measured for the gastrocnemius medialis (GM), vastus medialis oblique (VMO), vastus lateralis (VL), rectus abdominis (RA), and multifidus (MF) muscles. Normalized to the stable condition, WBV at 30 Hz and an unstable surface increased EMG in the GM vs the unstable and stable surfaces (~35%; p<0.05). VMO EMG decreased in the unstable vs stable condition (~20%), WBV at 30 Hz and an unstable surface increased EMG vs all other conditions (~20-40%; p<0.05). MF EMG increased with WBV at 30 Hz (25%; p<0.05) vs the stable condition but not vs all other conditions. Using an unstable surface during WBV exposure increases EMG of muscles in the lower extremities and trunk suggesting the combination of an unstable surface combined with WBV may be an effective modality to further increase EMG.

Objectives: To examine the post-exercise cross-transfer effects of acute whole body vibration (WBV). Methods: Seventeen healthy male volunteers (20.8±1.2 y) performed three unilateral vibration conditions in a randomized order: 1) WBV-50 Hz [high amplitude]; 2) WBV-30 Hz [low amplitude]; and 3) a control no WBV condition (Sham) applied to the dominant leg. Each condition involved maximal voluntary isometric contractions (MVC) followed by three leg press explosive repetitions (40% MVC) with non-dominant and dominant legs; which were conducted prior to and post vibration (immediately; 2 min and 5 min). Surface electromygraphy (sEMG) of the vastus lateralis (VL) and medial gastrocnemius (MG) were measured throughout each condition. Results:A condition x leg x time interaction effect was detected (p=0.001) where 50 Hz-High in the stimulated leg enhanced mean velocity at post-2 min compared to 30 Hz-Low and Sham, remaining elevated at post-5 min. Similarly, 50 Hz-High in the non-stimulated leg increased mean velocity at post-immediately and post-2 min compared to 30 Hz-Low and Sham. There were no changes in sEMG of VL and GM in the stimulated and non-stimulated post-conditions. Conclusion:WBV (50 Hz) can augment cross-transfer in neuromuscular performance. WBV could provide an alternate method of unilateral training to promote cross education explosive strength.

The primary objective of this investigation was to quantitatively identify which training variables result in the greatest strength and hypertrophy outcomes with lower body low intensity training with blood flow restriction (LIBFR). Searches were performed for published studies with certain criteria. First, the primary focus of the study must have compared the effects of low intensity endurance or resistance training alone to low intensity exercise with some form of blood flow restriction. Second, subject populations had to have similar baseline characteristics so that valid outcome measures could be made. Finally outcome measures had to include at least one measure of muscle hypertrophy. All studies included in the analysis utilized MRI except for two which reported changes via ultrasound. The mean overall effect size (ES) for muscle strength for LI-BFR was 0.58 [95% CI: 0.40, 0.76], and 0.00 [95% CI:-0.18, 0.17] for low intensity training. The mean overall ES for muscle hypertrophy for LI-BFR training was 0.39 [95% CI: 0.35, 0.43], and-0.01 [95% CI:-0.05, 0.03] for low intensity training. Blood flow restriction resulted in significantly greater gains in strength and hypertrophy when performed with resistance training than with walking. In addition, performing LI-BFR 2-3 days per week resulted in the greatest ES compared to 4-5 days per week. Significant correlations were found between ES for strength development and weeks of duration, but not for muscle hypertrophy. This meta-analysis provides insight into the impact of different variables on muscular strength and hypertrophy to LI-BFR training. © 2011 Springer-Verlag.

The purpose of this meta-analysis was to attempt to gain a clear picture of the magnitude of adaptations in muscular power expected after acute and chronic training, as well as identify specific factors that influence the treatment effects. Studies using a power training intervention and containing data necessary to calculate effect size (ES) were included in the analysis a total of 30 studies. Effect size demonstrated that the type of vibration platform used is a moderator of the treatment effect of vibration on power development is the type of vibration platform employed. Differences were noted in both acute and chronic changes in power when vertical vibration platforms were compared with oscillating platforms. Vertical platforms elicit a significantly larger treatment effect for chronic adaptations (ES = 0.99) as compared with oscillating platforms (ES = 0.36). The data also show that age is a moderator of the response to vibration exercise for power. On the basis of the overall analysis, it is apparent that vibration exercise can be effective at eliciting chronic power adaptations. Exercise professionals can include vibration exercise as a means of fostering power improvements. © 2010 National Strength and Conditioning Association.

The purpose of this meta-analysis was to attempt to gain a clear picture of the magnitude of strength improvements expected after acute and chronic vibration training and to identify specific factors that influence the treatment effects. Studies employing a strength training intervention and containing data necessary to calculate effect size (ES) were included in the analysis. A total of 31 studies met the inclusion criterion. Analysis of ES demonstrated that the type of vibration platform employed is a moderator of the treatment effect of vibration on strength development. Differences were noted in both acute and chronic changes in muscle strength when vertical vibration platforms are compared with oscillating platforms. Vertical platforms elicit a significantly larger treatment effect for chronic adaptations (ES = 1.24) compared with oscillating platforms (ES = -0.13). However, oscillating platforms elicit a greater treatment effect for acute effects (ES = 0.24) compared with vertical platforms (ES = -0.07). The data also show that gender, training status, and exercise protocol are moderators of the response to vibration exercise for strength development (vertical platforms). Based on the overall analysis, it is apparent that vibration exercise can be effective at eliciting chronic muscle strength adaptations. The vibration exercise can be used by exercise professionals to enhance muscular strength. © 2010 National Strength and Conditioning Association.

Following recent literature, we present a model of endogenous firm growth with R&D investment as one of the main mechanisms of growth. Our study evidences a positive effect of R&D intensity on the sales growth by using OLS, quantile regressions, and GMM system estimators for a sample of 754 European firms for the 2003-2007 period. We also find this association is more intense in high-growth firms and is especially significant when referring to high-technology sectors. This paper gives empirical support to those recommendations from policy makers and business leaders for maintaining the R&D expenditures especially in high-technology sectors even when facing a recession. © 2012 Elsevier B.V.

Sedano, S, Marín, PJ, Cuadrado, G, and Redondo, JC. Concurrent training in elite male runners: The influence of strength versus muscular endurance training on performance outcomes. J Strength Cond Res 27(9): 2433-2443, 2013- Much recent attention has been given to the compatibility of combined aerobic and anaerobic training modalities. However, few of these studies have reported data related to well-trained runners, which is a potential limitation. Therefore, because of the limited evidence available for this population, the main aim was to determine which mode of concurrent strength-endurance training might be the most effective at improving running performance in highly trained runners. Eighteen well-trained male runners (age 23.7 ± 1.2 years) with a maximal oxygen consumption (Vo2max) more than 65 ml·kg-1·min-1were randomly assigned into 1 of the 3 groups: Endurance-only Group (n = 6), who continued their usual training, which included general strength training with Thera-band latex-free exercise bands and endurance training; Strength Group (SG; n = 6) who performed combined resistance and plyometric exercises and endurance training; Endurance-SG (ESG; n = 6) who performed endurancestrength training with loads of 40% and endurance training. The study comprised 12 weeks of training in which runners trained 8 times a week (6 endurance and 2 strength sessions) and 5 weeks of detraining. The subjects were tested on 3 different occasions (countermovement jump height, hopping test average height, 1 repetition maximum, running economy (RE), Vo2max, maximal heart rate [HRmax], peak velocity (PV), rating of perceived exertion, and 3-km time trial were measured). Findings revealed significant time × group interaction effects for almost all tests (p < 0.05). We can conclude that concurrent training for both SG and ESG groups led to improved maximal strength, RE, and PV with no significant effects on the Vo2 kinetics pattern. The SG group also seems to show improvements in 3-km time trial tests. © 2013 National Strength and Conditioning Association.

Study design:Randomized two-group parallel.Objectives:The objective of this study was to analyze the adaptations on the popliteal artery (mean blood velocity (MBV), peak blood velocity (PBV), arterial resting diameter (RD) and blood flow (BF)) induced by 12 weeks of simultaneous application of whole-body vibration and electromyostimulation (WBV+ES) in patients with spinal cord injury (SCI). Secondarily, the musculoskeletal effects of this therapy on the gastrocnemius muscle thickness (MT) and femoral neck bone mineral density (BMD) were analyzed.Setting:Valladolid, Spain.Methods:Seventeen SCI patients (American Spinal Injury Association (ASIA) A or B) were randomly assigned to the experimental group (EG=9) or the control group (CG=8). Each subject was assessed in four different occasions: at baseline, after 6 weeks (Post-6) and 12 weeks of the treatment (Post-12) and 8 weeks after the end of the treatment (Post-20). Subjects in the EG performed 30 10-min sessions of WBV+ES during 12 weeks.Results:In the EG, RD increased compared with the baseline value at Post-6 (9.5%, P<0.01), Post-12 (19.0%, P<0.001) and Post-20 (16.7%, P<0.001). Similarly, in the EG, BF increased compared with the baseline value and with CG only at Post-12 ((33.9%, P<0.01) and (72.5%, P<0.05), respectively). Similarly, WBV+ES increased the MT of the gastrocnemius. BMD of both hips remained invariable during the study. CG showed no change at any point.Conclusions:WBV+ES improved popliteal artery BF, RD and MT after 12 weeks in SCI patients. This increase in RD remained above baseline after 8 weeks. The combination of WBV and ES could be considered a promising alternative to reverse the musculoskeletal atrophy and improve peripheral vascular properties in SCI patients.Spinal Cord advance online publication, 3 May 2016; doi:10.1038/sc.2016.60. © 2016 International Spinal Cord Society

Little by little, architecture comes closer to society more through sensations than through geometry. The architectonic culture has changed; the needs of the society have changed; we live in an era of "no places". In this paper, we will reflect about the place of what is modern, focusing on specific architectures that appear rootless from their location, since their time of permanence is brief. Thus, simply by handling everyday life, architecture can take us into the domain of dreams.

To determine whether 10 weeks of whole-body vibration (WBV) training has a significant effect on strength, muscle mass, muscle power, and mobility in older women, 26 subjects were randomly assigned to a WBV training group (n=13; mean age 79 years) and a control (CON) group (n=13; mean age 76 years). Maximal voluntary isometric contraction (MVIC) increased 38.8% in the WBV group, without changes in the CON group. Electromyographic activity of the vastus medialis (VM), the vastus lateralis, and the biceps femoris (BF) did not change in either group. Thigh muscle cross-sectional area increased significantly after training in VM (8.7%) and BF (15.5%). Muscle power at 20%, 40%, and 60% MVIC decreased from pre-test to post-test in the CON group; however, WBV training prevented the decrease in the WBV group. Consequently, mobility, measured by the Timed Up and Go test, increased significantly after training (9.0%) only in the WBV group. Ten weeks of lower limb WBV training in older women produces a significant increase in muscle strength induced by thigh muscle hypertrophy, with no change in muscle power. The adaptations to WBV found in the present study may be of use in counteracting the loss of muscle strength and mobility associated with age-induced sarcopenia. © 2009 John Wiley & Sons A/S.
