This study aimed to investigate the muscle fatigue and self-perceived exertion level on violin players before and after a training session. Fourteen professional violin players volunteered in this study. Surface electromyography (EMG) was used to record the fatigue level of the upper trapezius muscles before and after a training session. Medium Frequency (MF) of the EMG signals was used to document the fatigue rate of this muscle. Regression analysis and paired sample t-tests revealed no significant difference in the slopes of MF on both sides of trapezius muscle, before and after the training sessions. However, the Borg Scale ratings of perceived exertion revealed significant increase in fatigue level (p=0.003) after the training session. The disparity in the subjective perception with the objective findings indicated that the violists' self-perceived exertion arises from multiple sources. The high prevalence of playing-related musculoskeletal complaints (79%) in this group of players warrants further ergonomic investigation of possible work-related risk factors.

The aim of this research paper was to examine the voice quality of sports coaches using the objective (acoustic) method. A total of 28 sports coaches (mean age 28.58, SD=5.08), from the City of Zagreb participated in this research. Recordings of the phonation of the vowel /a/ before and after one training session were obtained and analyzed using the PRAAT Program. Mean, minimal and maximal values of fundamental frequency, shimmer, jitter and harmonics-to-noise ratio were observed. The statistical analyses showed no statistically significant difference in acoustic voice quality of male and female coaches before and after the training session, or between male and female coaches. However, intra-individual differences among participants were observed, which may be significant in terms of their potential to affect the quality of their voices in the future.

ABSTRACT``Myofascial pain syndrome in upper trapezius muscle is a muscle pain that implicated by one or somemyofascial trigger points in upper trapezius muscle. Working with static position in long time stimulating the presence ofmyofascial trigger points that causing pain and movement limitation of the neck that stimulate neck disability. Physicaltherapy’s intervention for reducing pain in this case could be integrated neuromuscular inhibition technique or contractrelax stretching combined with ultrasound modality. Purpose: to compare the both interventions in reducing neckdisability of myofascial pain syndrome in upper trapezius muscle. Method: this was an experimental study withRandomized Pre and Post Test Group Design. Samples were divided into 2 treatment group that consist 12 samplesfor each group. The first group treated with integrated neuromuscular inhibition technique with ultrasound while thesecond group treated with contract relaxes stretching with ultrasound. The data was collected by measuring neck rangeof motion using goniometer at the time before and after treatment. Result: the 1st group showed that the Neck ROMincrease 5.083±1.0840 (p<0.001) and the 2nd group showed that the Neck ROM increase 3.333±0.7780(p<0.001). Itmeans there were significant effect of each treatment in both groups. The results of independent t-test showed p<0.001,so that there was significant difference of increased Neck ROM between these groups. The result of independent t-testshowed p value 0.001, so there was significant difference between two groups at increasing neck ROM. Conclusion:combination integrated neuromuscular inhibition technique is more effective than contract relax stretching to ultrasoundmodality in increasing neck range of motion of myofascial syndrome in upper trapezius muscle.Keywords: myofascial, neck disability, trapezius, INIT, ultrasound, stretching

Purpose:To assess the weekly fluctuations in workload and differences in workload according to playing time in elite female basketball players.Methods:A total of 29 female basketball players (mean [SD] age 21 [5] y, stature 181 [7] cm, body mass 71 [7] kg, playing experience 12 [5] y) belonging to the 7 women’s basketball teams competing in the first-division Lithuanian Women’s Basketball League were recruited. Individualized training loads (TLs) and game loads (GLs) were assessed using the session rating of perceived exertion after each training session and game during the entire in-season phase (24 wk). Percentage changes in total weekly TL (weekly TL + GL), weekly TL, weekly GL, chronic workload, acute:chronic workload ratio, training monotony, and training strain were calculated. Mixed linear models were used to assess differences for each dependent variable, with playing time (low vs high) used as fixed factor and subject, week, and team as random factors.Results:The highest changes in total weekly TL, weekly TL, and acute:chronic workload ratio were evident in week 13 (47%, 120%, and 49%, respectively). Chronic workload showed weekly changes ≤10%, whereas monotony and training strain registered highest fluctuations in weeks 17 (34%) and 15 (59%), respectively. A statistically significant difference in GL was evident between players completing low and high playing times (P = .026, moderate), whereas no significant differences (P > .05) were found for all other dependent variables.Conclusions:Coaches of elite women’s basketball teams should monitor weekly changes in workload during the in-season phase to identify weeks that may predispose players to unwanted spikes and adjust player workload according to playing time.

The purpose of this study is to evaluate the effectiveness of radial shock waves in myofascial upper trapezius syndrome following the global treatment scheme of key trigger points. Materials and methods 26 patients treated with rESWT (Radial shock wave therapy) after a global postural and myofascial assessment of the patient and the identification of the key trigger points. At the end of the treatment each subject was re-evaluated through the Numerical Rating Scale - NRS and through the examination with Electronic Baropodometer. In this study, we compared the values of NRS and the values of postural biometrics before and after 2 sessions of rESWT, and a statistically significant difference (P <0.05) in all measurements emerged in the values measured with NRS. In the static percentage load, a statistically significant reduction in the percentage load differences (right / left) (P <0.05) was observed in all three evaluation moments (T0, T1, T2). The percentage and statistically significant improvement (P <0.05) were recorded at time T2 in the surface of the ellipse. Greater control of balance and greater awareness of the base of support was found in the calculation of the sway path, in particular with closed eyes. Based on this experience, the use of radial shock waves in pathologies related to myofascial pain with postural implications would be desirable.

Pilates Method

Abstract Background: Currently there are campaigns to raise the awareness of the need to practice some physical exercise with several objectives, mainly as a preventive character. From this perspective, we can see the use of the Pilates method as an instrument of therapeutic exercise for the protection and promotion of health. However, despite being popularly performed, there is still no scientific evidence on the standardization of the use of the method and its progression to an adequate prescription of physical training. Therefore, the purpose of the study was to develop a protocol to monitor the progression of Pilates loads daily between the basic, intermediate and advanced levels, as well as to analyze the effect of the method on the psychometric, cardiorespiratory and autonomic parameters. Methods: there will be a total of 36 sessions of Pilates mat for 32 healthy men. In each training session, initially, cardiorespiratory parameters, pain through the Visual Analogue Scale (VAS), and a psychometric questionnaire will be collected for the volunteers. Heart rate (HR), subjective perception of effort (SPE), and RR intervals will be measured during the sessions for subsequent use to analyze the progression of the loads by monitoring the internal training load and heart rate variability (HRV), respectively. At the end of the sessions, cardiorespiratory parameters, the VAS, the psychometric questionnaire will be measured again and the participants will only be released after 15 minutes of rest for the final HR analysis and to re-respond to the PSE scale. Before and after the 36 sessions of training, participants will also be evaluated in relation to psychometric, cardiorespiratory, and autonomic parameters. Discussion: this study deserves to be highlighted as it is a parallel randomized clinical trial with standardization of training, with the purpose of monitoring the prescription of loads of the method, as well as verifying its efficacy in clinical, cardiorespiratory, and autonomic outcomes. The easy reproducibility of the protocol from its description, also improves the study, besides providing support for prescribing the method to the professionals involved.

The Impact

BACKGROUND: Physical symptoms present in a large percentage of instrumental musicians at all levels of expertise, yet the impact of these symptoms on patterns of muscle use and perceived exertion during performance is still unclear. PURPOSE: Quantify the effects of physical symptoms on muscle activity and perceived exertion in skilled violinists during a range of bowing actions. METHODS: Fifty-five professional or university (undergraduate or postgraduate) violinists performed 5 randomly ordered 45-second musical excerpts designed to elicit a range of right arm bowing actions. Surface electromyography data were obtained from 16 muscles of the trunk, shoulder, and right arm during each excerpt performance. Sites of current physical symptoms were reported using a pre-test questionnaire. Average rating of perceived exertion (RPE) for the excerpt performances was obtained immediately after the final excerpt performance. RESULTS: Right upper trapezius muscle activity levels were significantly reduced in participants reporting right shoulder symptoms (p<0.05). Violinists with right wrist symptoms displayed global increases in average muscle activity across all investigated muscles (p<0.03). RPE did not differ significantly between any groups of symptomatic and asymptomatic participants. CONCLUSION: Differential muscle activity patterns appear between right shoulder symptomatic, right wrist symptomatic, and asymptomatic violinists, presenting the possibility of altered biomechanical responses to physical symptoms that vary with symptom location.
