El presente estudio surge como fruto de la experiencia como instrumentista de viento, que ha llevado a tomar consciencia sobre los distintos problemas que son comunes a los instrumentistas de esta familia; aunque, concretamente, se ha partido de la observación de los saxofonistas. El adecuado trabajo de la técnica respiratoria diafragmática en el aula instrumental, tranquilizará el sistema nervioso, facilitará la comunicación entre los hemisferios cerebrales y equilibrará la energía del músico; trabajo que se verá potenciado gracias a la aplicación de diversas técnicas respiratorias durante el proceso de aprendizaje respiratorio en clase. Este artículo muestra un estudio exploratorio acerca de los principales problemas que aquejan a los músicos y las formas de afrontarlo desde el aula de Saxofón que siguen los docentes; así, se ha podido comprobar que, a nivel pedagógico, la escasez bibliográfica queda justificada por la falta de importancia didáctica que se le da en el aula.AbstractThe present study arises as a result of the experience as an instrumentalist of wind, which has led to taking awareness of the various issues that are common to the instrumentalists of this family; Although, in particular, has started from the observation of the saxophonists. Proper work of the diaphragmatic breathing technique in the instrumental classroom, reassured nervous system, will facilitate communication between the cerebral hemispheres and balance the power of the musician; work, which will be enhanced through the application of different breathing techniques during the process of respiratory learning in class. This article shows an exploratory study about the main problems afflicting musicians and forms of address it from the classroom of saxophone following teachers; Thus, is has been found that educational level, the bibliographic shortage is justified by the lack of didactic importance given in the classroom.

Tuberculosis (TB) is a contagious disease caused by the bacterium Mycobacterium Tuberculosis and can spread from one person to another through the sputum droplet air transmission of the patient. Non-pharmacological management of pulmonary tuberculosis includes bed rest, semi-fowler position, comfortable environment, personal hygiene, diaphragm breathing. The purpose of this EBN is to determine the effect of diaphragmatic breathing and pocketed lip breathing on the handling of breathlessness in patients with ineffective respiratory disorders with mycobacterium tuberculosis (pulmonary TB). The implementation strategy used the techniques of literature review obtained through the online search process. The search was conducted via Google Scholar. Pursed lip breathing and diapragmatic breathing are effective in the management of breathlessness in patients with ineffective breathing patterns.

This study compared undifferentiated ratings of perceived exertion (RPE) during short duration, very high intensity cycle exercise using high and low resistance. 30 recreationally trained males (24.2 ± 2.4 yr.) were memory-anchored to the Borg 15-category scale. The high and low resistance exercises were defined by 30-sec. maximum tests assigned in counterbalanced order, with resistances set before testing during an orientation session. High resistance was 10% of body mass. Low resistance resulted in the same total work as the high resistance over the 30-sec. sessions (± 5%) but increased pedal rate. RPE was taken at 8, 13, 18, 23, and 28 sec. during the high and the low resistance exercises. Measurements were compared using a 2-way repeated-measures analysis of variance. RPE was significantly greater ( p = .005) for the high than the low resistance exercise at each interval. RPE increased when the subjects were required to pedal against a greater resistance and produce the highest forces. These RPE data are consistent with data from both aerobic cycle and resistance exercise. The data suggest that instantaneous force production, not summed work, is a primary determinant of RPE. All of these observations support Cafarelli's theoretical model of effort sense. In conclusion, as an individual generates more force during high resistance exercise than in light resistance exercise, a potential explanation of our results is that the increased motor outflow and corollary sensory signal lead to a greater sense of effort.

AbstractPrior research about the effects of the amount of exercised muscle mass upon cardiovascular responses (CVR) has neglected a potential bias related to total exercise and concentric/eccentric duration. Autonomic responses and perceived exertion (RPE) were compared in resistance exercises performed with larger and smaller muscle mass and matched for total exercise and concentric/eccentric duration. Twelve men performed 4 sets of 12 repetitions of unilateral (UNI) and bilateral (BIL) knee extensions at 70% of 12RM. Increases in CVR were always greater at the last set of BIL over UNI, as were SBP (35% vs. 23%), DBP (36% vs. 23%), HR (40% vs. 26%), RRP (90% vs 53%) and CO (55% vs 39%). No difference between protocols was found for autonomic modulation before and after exercise, but BIL induced significantly greater changes than UNI from baseline for R-R intervals (−13% vs. −7%), SDNN (−38% vs. −17%) and rMSSD (−41% vs. −21%). The rate of perceived exertion in the last set was higher in BIL than UNI (7.6±0.5 vs. 6.6±1.4 OMNI-RES; P<0.05) and did not correlate with any CVR. Thus, CVR were greater in resistance exercise performed with larger than smaller muscle mass. This information is relevant for patients with high cardiovascular risk.

The primary purpose of this study was to examine the acute effects of one versus two doses of a multi-ingredient pre-workout supplement on energy expenditure during moderate-intensity treadmill running. In addition, our second aim was to investigate the responses of associated metabolic factors (i.e., substrate utilization, measures of gas exchange), perceived exertion, and resting cardiovascular variables with one and two doses of the pre-workout supplement. Twelve females (mean ± SD: age = 25.3 ± 9.4 years; body mass = 61.2 ± 6.8 kg) completed three bouts of 30 min of treadmill running at 90% of their ventilatory threshold on separate days after consuming one dose of the pre-workout supplement (1-dose), two doses (2-dose), and a placebo. There were no differences among conditions for energy expenditure, fat or carbohydrate oxidation, respiratory exchange ratio, oxygen consumption, or heart rate across exercise time. The two-dose group, however, had lower (p = 0.036) ratings of perceived exertion (11.8 ± 1.7) than the one-dose (12.6 ± 1.7) and the placebo (12.3 ± 1.2) at the 20-min time point of exercise as well as greater resting systolic blood pressure (110 ± 10 mmHg) compared to the one-dose (106 ± 10 mmHg) and the placebo (104 ± 10 mmHg) conditions. Both the one-dose and two-dose conditions had greater increases in diastolic blood pressure compared to the placebo. Thus, our findings indicated that the present pre-workout supplement had no performance-enhancing benefits related to energy metabolism but did attenuate feelings of exertion.

Context: Muscle dysfunction is common in patients with chronic ankle instability (CAI). Blood flow restriction (BFR) may enhance muscle responses during exercise and provide an opportunity to enhance muscle adaptations to ankle rehabilitation exercises; however, there is no evidence examining the effect of BFR on muscle function in CAI patients. Objective: Examine the effects of BFR on muscle activation and oxygen saturation during submaximal ankle eversion and dorsiflexion exercises in individuals with CAI. Design: Cross-over study design. Setting: Laboratory setting. Patients (or Other Participants): Nineteen young adults with a history of CAI. Interventions: Participants performed 4 sets (30, 15, 15, and 15) of eversion and dorsiflexion resistance exercises at 30% of maximum voluntary isometric contraction during 2 conditions, BFR and control. For BFR, a cuff was applied above the knee at 80% of blood flow occlusion. For control, the cuff was not inflated. Main Outcome Measures: Fibularis longus and tibialis anterior electromyography muscle activation, lower-leg muscle oxygen saturation, and ratings of perceived exertion were recorded during exercises. Results: Average grand mean muscle activation was 5.6% greater during eversion (P = .03) and 7.7% greater during dorsiflexion (P = .01) resistance exercises with BFR compared with control; however, the magnitudes of the effects of BFR were only clinically important during the dorsiflexion exercises. Lower-leg muscle oxygen saturation was 31% to 44% lower (P < .001) during BFR exercises. Ratings of perceived exertion were significantly higher during BFR exercises (P < .001). Conclusions: Greater muscle activation and hypoxia were present during submaximal resistance exercise with BFR in participants with CAI. Greater muscle activation and hypoxia during BFR exercises may be important acute responses mediating the training-related muscle adaptations that have been observed with BFR. The presence of these acute responses in CAI patients supports further research examining BFR as a potential ankle rehabilitation tool.

Escalas de percepção subjetiva de esforço têm sido usadas há bastante tempo para se referir à intensidade de esforço no exercício aeróbio. Somente há pouco tempo foi validada a escala de OMNI-RES para exercício resistido, de modo que sua aplicação em algumas populações ainda é escassa. Assim, o objetivo deste estudo foi avaliar a efetividade da escala de OMNI-RES em mulheres idosas hipertensas. Vinte e uma voluntárias (60.2±3,8 anos, IMC de 28,7±1,2 Kg/m2), realizaram quatro sessões de exercício resistido randomicamente ordenadas. Duas das sessões eram para membros inferiores (MI), com intensidades de 60% e 80% de 15 RM, e as outras duas, para membros superiores (MS), com as mesmas intensidades. As sessões tiveram três séries de 15 repetições e intervalos de 90 segundos. Ao final de cada série, mediu-se a frequência cardíaca e a percepção subjetiva foi referida pelas mulheres. Para a análise estatística, foi utilizado o teste de ANOVA two-way. A frequência cardíaca se apresentou significativamente mais elevada nas sessões a 80% de 15RM em relação a 60% de 15RM em todas as séries, tanto de membros superiores quanto de membros inferiores. Nos protocolos para MI, as mulheres referiram pontuações na escala de OMNI-RES sempre significativamente maiores ao final das três séries, com intensidade de 80% em relação a 60% de 15 RM (6,1±0,1 versus 3,7±0,1; 6,1±0,1 versus 3,8±0,2 e 6,1±0,1 versus 3,9±0,2 para as 1ª, 2ª e 3ª séries a 80 e 60% respectivamente). Nos protocolos para MS a pontuação na escala de OMNI-RES foi igualmente maior para os exercícios a 80% de 1RM em todas as séries (6,1±0,1 versus 3,5±0,1; 6,1±0,1 versus 3,5±0,1 e 6,1±0,1 versus 3,6±0,1 para as 1ª, 2ª e 3ª séries a 80 e 60% respectiva  mente). Os valores de pontuação foram equivalentes à classificação de razoavelmente leve e compatível com treino de endurance muscular segundo a escala de OMNI-RES nos exercícios a 60% de 15 RM e razoavelmente pesado e compatível com treinamento de hipertrofia para a intensidade de 80% de 15RM. Concluiu-se que a escala de OMNI-RES representa adequadamente a intensidade adotada em exercícios resistidos com características de Resistência Muscular Localizada (RML) e hipertrofia em mulheres idosas hipertensas. THE USE OF THE OMNI-RES SCALE IN HYPERTENSIVE ELDERLY abstract Scales of perceived exertion have been used for some time to refer to the intensity of effort in an aerobic exercise. Only recently the OMNI-RES scale has been validated for resistance exercise, as a result of that its application in some populations is still scarce. Thus, the purpose of this study was to evaluate the effectiveness of the OMNI-RES scale in elderly women with hypertension. Twenty one volunteers (60,2 ± 3,8 years, BMI 28,7 ± 1,2 Kg/m2), undertook four sessions of resistance exercise ordered randomly. Two of those sessions were for lower limbs at intensities of 60% and 80% of 15RM, and the other two were for upper limbs with the same intensity. The sessions had 3 sets of 15 repetitions and intervals of 90 seconds. At the end of each series it was measured the heart rate and the subjective perception was reported by the women. For statistical analysis, it was used the two-way ANOVA test. Heart rate was significantly higher in sessions at 80% with 15RM than at 60% with 15RM in all series, both upper limbs and lower limbs. In the protocols for lower limbs, the women always reported significantly higher scores on the OMNI-RES at the end of the three series with an intensity of 80% compared to 60% with 15 RM (6,1 ± 0,1  versus 3,7 ± 0,1; 6,1 ± 0,1 versus 3,8 ± 0,2 and 6,1 ± 0,1 versus 3,9 ± 0,2 for the 1st, 2nd and 3rd grades 80 and 60% respectively). The values in scores were equivalent to the classification of fairly mild consistent with muscle endurance training according to the OMNI-RES scale on the exercises at 60% with 15 RM and fairly heavy and consistent with hypertrophy training at an intensity of 80% with 15RM. It was concluded that the OMNI-RES scale adequately represented the adopted intensity in resistance exercises with features of RML and hypertrophy in hypertensive elderly women.
