Vibration Training

This study investigated the effects of a short-term vibration training intervention, using a relatively low-cost side-alternating platform, on the jump performance and corresponding lower body power of a young recreationally active female population. Following institutional ethics approval, nine recreationally active females (mean: age = 21.1 ± 0.6 years; height = 1.66 ± 0.08 m; mass = 68.1 ± 9.8 kg), recruited via a convenience sampling method, were randomly assigned to a whole-body vibration training (WBVT) or control group. The WBVT group performed static squats and lunges, once-per-week over a six-week period, on a side-alternating vibration platform. The control group followed an identical training protocol without vibration exposure. Lower body muscular power was assessed pre- and post- intervention using three maximal vertical countermovement jumps (VCMJ), performed on a contact mat. Results of a repeated measures t-test revealed the WBVT group significantly improved their VCMJ performance (P= 0.012) over the six-week intervention. The control groups’ performance remained relatively stable with no significant increase in jump performance (P =0.68). The current study supports the inclusion of vibration training as part of an exercise regime to increase jumping performance and power in a recreationally active female population. As findings show comparable improvements to those from other studies following similar training protocols, using more expensive vibration platforms, further investigation is now warranted to ascertain responses to vibratory signals received from the variety of low-cost, vibration platform types currently available.

Typing Task

The study evaluated effects of sitting and standing work postures on objective short-term computer typing performance and perceived discomfort. A randomized, repeated measures, study design was used to assess typing performance and perceived discomfort for 12 participants on a 15-minute computer-typing task. Typing performance was measured by number of characters typed and number of errors. Perceived discomfort was measured for the whole body, as well as for upper body and lower body, using a visual analog scale. Results suggest that for a short-term computer typing task, compared to a sitting work posture a standing work posture leads to fewer typing errors without impacting typing speed. Overall levels of perceived discomfort for the whole body are similar for sitting and standing work postures. However, for perceived discomfort there is an interaction of work posture and body region - upper body discomfort is higher in the sitting work posture while lower body discomfort is higher in the standing work posture.

The purpose of this study is to determine the effects of coupling WBV and acute muscular fatigue to determine its effects on countermovement vertical jump (CMVJ) performance and isometric mid-thigh pull (IMTP). Twenty-eight healthy active adults volunteered for five-day study. Testing sessions 2–5 included one of four conditions: No WBV and no fatigue (CON), WBV and fatigue (WBV + FAT), WBV and no fatigue (WBV), and no WBV and fatigue (FAT). WBV was performed using a frequency of 50 Hz and a low amplitude while performing quarter squats for a total of 4 min with a 30 s rest or work ratio. Lower-body fatigue induced using Bosco fatigue protocol. CMVJ and IMTP were performed on force plates. SPSS was used to perform a 2 × 2 Repeated Measures ANOVA. Significant main effects were found for fatigue in CMVJ-height and CMVJ-peak ground reaction force, no significant main effect for WBV, and no significant interactions. Lower-body fatigue decreases vertical jump performance, and WBV did not attenuate the detrimental effects of lower-body fatigue.

Purpose: To examine the effects of a 6-month whole-body vibration (WBV) training on lower-body strength (LBS), lower-body power (LBP), and swimming performance in adolescent trained swimmers. Methods: Thirty-seven swimmers (23 males and 14 females; 14.8 [1.3] y) were randomly assigned to the WBV (n = 20) or the control group (n = 17). Isometric LBS (knee extension and half squat) and LBP (vertical and horizontal jumps and 30-m sprint) tests were performed before and after the intervention period. Swimming performance times in 100 m were collected from official competitions. As time × sex interaction was not found for any variable (P > .05), males and females were analyzed as a whole. Results: Within-group analyses showed a most likely beneficial moderate effect of WBV on isometric knee extension (effect size [ES] = 0.63), 30-m sprint test (ES = 0.62), and 100-m performance (ES = 0.25), although these were corresponded with comparable small to moderate effects in the control group (ES = 0.73, 0.71, and 0.20, respectively). The control group obtained a small possibly beneficial effect of swimming-only training on vertical jump performance, whereas no effect was observed in the WBV group. Unclear effects were observed for the rest of the variables assessed. Between-group analyses revealed unclear effects of WBV training when compared with the control condition in all studied variables. Conclusions: There is no current evidence to support the use of WBV training, and therefore, coaches and sports specialists should select other methods of training when the aim is to increase LBS, LBP, or swimming performance.

Abstract Background Electronic cigarettes have been a popular alternative to tobacco smoking. The effect of tobacco smoking on nasal airway resistance has been investigated before; however, the effect of the aerosol generated by electronic cigarettes is still unknown. This study aimed to evaluate the short-term effects of e-cigarettes on nasal airway resistance. Methods Sixty-one participants were recruited into a vapers group and a control group. The vapers group was instructed to smoke for 5 minutes, and their nasal resistance was measured pre-procedure and at 1 and 5 minutes post-procedure. The results were compared between both groups. Results Repeated measures analysis of variance demonstrated that vaping has no statistically significant effect on total nasal airway resistance. Conclusion Although the differences between both groups were not statistically significant overall, the vapers group showed a reduction in nasal airway resistance in the short term.

AbstractBackground & ObjectivesThe douche, one of the hydrotherapeutic treatment modality is commonly used by Naturopathy physicians as a treatment of choice in the management of several ailments. This study was done to assess the effect of full body neutral douche in the management of pain and systemic symptoms in adult females with primary dysmenorrhoea.Methods68 subjects of age 18-22 years with primary dysmenorrhoea were recruited for the study and were randomly divided into two groups: the experimental group (n = 34) and the control group (n = 34). The experimental group received whole body neutral douche, whereas the control group followed the routine as usual. Assessments for the pain, systemic symptoms and menstrual cramps were done by using McGill Pain Questionnaire, Verbal multidimensional scoring system and analog scale for severity of pain and menstrual cramps respectively at baseline, day 30 and day 60 of intervention. Two- way repeated measures of ANOVA was performed to understand the between group changes, adjusted for the respective baseline values and age.ResultData was analyzed with SPSS (Version 21.0) package. Neutral douche resulted in significant improvement in pain [F(2,66) = 114.564, p < 0.0005, partial ?2 = 0.771], severity of pain [F(2,66) = 70.418, p < 0.0005, partial ?2 = 0.681], cramps [F(2,66) = 75.986, p < 0.0005, partial ?2 = 0.697] and systemic symptoms [F(2,66) = 14.64, p < 0.0005, partial ?2 = 0.307] as compared to the control group.ConclusionFindings suggest that neutral douche can be used as a non-pharmacological intervention in the management of pain and systemic symptoms in primary dysmenorrhea.

Abstract Background Hemiplegic cerebral palsy (CP) enormously affects the quadriceps and hamstring muscles. It causes weakness in the affected lower-extremity muscles in addition to muscle imbalance and inadequate power production, especially in the ankle plantar-flexor and knee extensor muscles. It also causes anomalous delayed myoelectrical action of the medial hamstring. A whole-body vibration (WBV) exercise can diminish muscle spasticity and improve walking speed, muscle strength, and gross motor function without causing unfavorable impacts in adults suffering from CP. Thus, the aim of this study is to investigate the impacts of WBV training associated with conventional physical therapy on the quadriceps and hamstring muscle strength, endurance, and power in children with hemiparetic CP. Results The post-intervention values of the quadriceps and hamstring muscle force, endurance, and power were significantly higher than the pre-intervention values for both groups (p = 0.001). The post-intervention values of the study group were significantly higher than the control group (quadriceps force, p = 0.015; hamstring force, p = 0.030; endurance, p = 0.025; power, p = 0.014). Conclusion The 8 weeks of WBV training that was added to traditional physical therapy was more successful in improving the quadriceps and hamstring muscle strength, endurance, and power in children with hemiparetic CP when compared to traditional physical therapy alone.

Abstract Background: Attention and memory deficits are common following paediatric acquired brain injury (ABI). However, there are few evidence-based interventions to improve these domains and benefit the everyday life of children post-injury. The Amsterdam Memory and Attention Training for children (Amat-c) has been translated from Dutch to English and shown to improve attention and memory skills in children following ABI. This protocol describes a study to expand accessibility of the program by using online, clinician-supported delivery with children post-ABI. Method/design: The study is a randomized controlled trial. Participants will be 40 children aged 8–16 a minimum of one-year post-ABI. Participants in the treatment group will complete 18 weekly sessions of the Amat-c program with weekly online clinician support. Participants in the active-control group will be administered ABI psychoeducation via a booklet for parents, with weekly online clinician contact. Attention and memory will be assessed at three time points up to six months post-intervention. Results: Analysis will be repeated measures multivariate planned comparisons; using the Statistical Package for the Social Sciences (IBM SPSS Statistics) General Linear Model procedure will compare pre- and post-intervention and six-month follow-up outcomes. Discussion: If shown efficacious in improving attention and memory, our team will then take a key role in implementing Amat-c into clinical care.

We investigated whether depressed patients who received fMRI-based neurofeedback are able to upregulate the activity in brain areas devoted to positive emotion processing and thereby establish improvements in mood state. Eight medicated patients with major depression participated in four separate fMRI sessions, each of which consisted of an emotion localiser and three neurofeedback runs. Target areas were selected individually with a functional localiser that identified the region most responsive to positive affective images. The target areas were in uni- or bilateral prefrontal cortex, insula or amygdala. During neurofeedback runs, patients received real-time feedback about activation levels in the target area. Each patient learnt to increase target area activity over successive sessions. Depression scores on the 17-item Hamilton Depression Rating Scale improved significantly. No such improvement was seen in a non-neurofeedback control group (N = 8) that was matched for symptom severity, demographics and medication and used the same cognitive/affective strategies that were employed successfully by the neurofeedback group, but outside the scanner. This group difference in treatment effects was supported by a significant interaction between the factors time (pre/post-intervention) and group (neurofeedback/controls) on the repeated measures ANOVA (F(1,14) = 10.15, p = .007). The neurofeedback group showed increasing activity in the ventral striatum and regions involved in cognitive control as training progressed. Upregulation of brain areas responsive to positive affective cues through fMRI-neurofeedback is thus a promising tool in the treatment of depression. The novelty of the present approach consists in the combination of biological and cognitive factors in the same intervention.

Objective: To verify the effect of recreational soccer on bone mineral density and sarcopenia in the elderly. Methods: Fourteen elderly people aged 65.9 ± 3.4 years were selected. They were separated into two groups: the intervention group and the control group; the intervention group played recreational soccer for 12 weeks on two days of the week. Assessments were performed for bone mineral density and body muscle mass before and after the intervention. For statistical analysis, the repeated measures ANOVA with Bonferroni’s post hoc test was used. Results: After 12 weeks, there was a significant change in bone mineral density in the region of the total femur (p = 0.020). Analyzing the participants’ sarcopenia, no significant results were found after the intervention period. Conclusion: Playing recreational soccer causes a significant improvement in the total femur and maintains bone regions in the spine, whole body, and femoral neck. Also, it promotes a removal from the threshold for sarcopenia screening in the elderly.
