Presentation of the ATLETAS DA VOZ™ Conditioning Program

Objectives: To present a simple form of vocal and breathing conditioning for voice professionals based on concepts from vocal science. The vocal conditioning program called Voice Athletes Conditioning uses the principles of exercise physiology to gradually improve vocal and respiratory overload to achieve endurance, power, and flexibility. Methods: Due to our personal experience with high voice users, we synthesized a vocal conditioning program (AVCP) that combines voice science, exercise physiology, sports science and physical therapy principles. This is an 8-week program of daily vocal and breathing exercises with overload enhancement each week using different types of breathing devices and semi-occluded vocal tract exercises, designed and developed according to the specific requirements and performance of the voice professional. Reflections: Professional voice users often experience episodes of vocal fatigue that can directly affect their performance and vocal health. As with physical training for athletes, voice exercises can also contribute to improving vocal conditioning, preventing voice disorders, as well as helping to obtain better performance, greater tolerance to fatigue and shorter recovery time. Conclusions: AVCP is an approach that considers the principles of muscle training aimed objectively at the respiratory and vocal muscles, carried out with a variety of breathing devices and specific vocal exercises in search of greater performance time, less physiological stress, and shorter recovery time in the professional use of the voice.

A resistência do fluxo inspiratório modifica a intensidade de uma sessão de pilates? / Does inspiratory flow resistance modify the intensity of a pilates session?

INTRODUÇÃO: As evidências sobre a melhora da capacidade funcional utilizando o Método Pilates não são contundentes. Uma possibilidade de melhorar o efeito de uma sessão de Pilates sobre a capacidade cardiorrespiratória de seus praticantes é utilizar a resistência de fluxo inspiratório (RFI) de forma concomitante. Esse efeito pode ser visualizado através da determinação do limiar glicêmico (LG), técnica utilizada como marcador de intensidade do exercício. OBJETIVO: Testar a hipótese de que a utilização de RFI em uma sessão de pilates antecipa o LG. MÉTODOS: Estudo crossover de corte transversal. Foram avaliados 26 indivíduos de ambos os sexos, sendo 10 do sexo masculino, sadios e com idade entre 20 e 40 anos. Os voluntários foram randomizados para dois protocolos: Protocolo RFI ­ 11 movimentos do Método Pilates com RFI utilizando 20% da pressão inspiratória máxima; e Protocolo sem RFI (SRFI) ­ 11 movimentos do Método Pilates sem RFI. Os dois protocolos foram realizados no mesmo dia, sendo um pela manhã e outro à tarde, conforme randomização feita por sorteio aleatório simples. No repouso e ao final de cada movimento coletas de sangue capilar foram realizadas para dosagem da glicemia e construção da curva glicêmica. O LG foi determinado no menor ponto da curva. RESULTADOS: O LG foi antecipado no protocolo que utilizou RFI, ou seja, no protocolo com RFI o LG foi visualizado no sexto exercício, enquanto no protocolo SRFI o LG foi visualizado no nono exercício (p<0,05). CONCLUSÃO: A RFI antecipou o LG, o que sugere que a RFI aumenta a intensidade de uma sessão de pilates. Isso aventa a hipótese de que a RFI pode proporcionar a médio e longo prazo benefícios adicionais aos praticantes do Método Pilates.

INTRODUCTION: The evidence on the improvement of functional capacity using the Pilates Method is not conclusive. One possibility to improve the effect of a Pilates session on the cardiorespiratory capacity of its practitioners is to use the inspiratory flow resistance (IFR) concomitantly. This effect can be visualized by determining the glycemic threshold (GT), a technique used as an exercise intensity marker. OBJECTIVE: To test the hypothesis that the use of IFR in a Pilates session anticipates GT. METHODS: Cross-sectional crossover study. A total of 26 individuals of both genders were evaluated, 10 of whom were male, healthy, and aged between 20 and 40 years. The volunteers were randomized to two protocols: Protocol IFR - Eleven movements of the Pilates method with IFR using 20% of the maximum inspiratory pressure, and Protocol no IFR (NIFR) - Eleven movements of the Pilates method without IFR. The two protocols were performed on the same day, one in the morning and the other in the afternoon, according to randomization by simple random draw. At rest and at the end of each movement, capillary blood collections were performed to measure blood glucose and construct the glycemic curve. GT was determined at the smallest point on the curve. RESULTS: The GT was anticipated in the protocol that used IFR; that is, in the protocol with IFR, the GT was visualized in the sixth exercise, while in the NIFR protocol, the GT was visualized in the ninth exercise (p<0.05). CONCLUSION: IFR anticipated GT, which suggests that IFR increases the intensity of a Pilates session. This suggests the hypothesis that IFR can provide additional medium and long-term benefits to Pilates method practitioners.

Application of early respiratory training program based on 4E model in children with bronchiolitis obliterans / 中国实用护理杂志

Objective:To explore application effect of early respiratory training schemes based on 4E mode (Engage, Educate, Execute, Evaluate) in children with bronchiolitis obliterans (BO) and provide evidence for the clinical implementation of early respiratory rehabilitation in children with BO.Methods:This was a quasi-experimental study. The children with BO who were admitted to 2 wards of the Department of Respiratory Medicine of Hunan Children's Hospital from January 1 to December 31, 2021 were selected as the research objects. They were randomly divided into the control group and the experimental group, with 23 cases in each group. The control group received routine treatment, nursing and rehabilitation guidance. The experimental group established a multidisciplinary team based on the control group, and used the early respiratory training program based on the 4E model to implement intervention. The clinical symptom severity scale was used to evaluate the improvement of the clinical symptoms of the children within 24 hours of being diagnosed as BO, the day of discharge, and 1 and 3 months after discharge for re-examination, and the hospitalization time of the children and the incidence of adverse events related to respiratory training were counted by using medical records and questionnaires.Results:The clinical symptom severity scores of the experimental group within 24 hours of admission diagnosis and the day of discharge were (20.00 ± 2.51) and (11.30 ± 2.46)points respectively, while those of the control group were (20.57 ± 2.21) and (11.70 ± 2.42) points respectively, with no statistically significant difference ( t=0.81, 0.54, both P>0.05). The clinical symptom severity scores of the experimental group were(10.52 ± 2.31) and (8.55 ± 1.06) points, lower than (12.32 ± 1.39) and (12.45 ± 2.19) points of the control group when they returned to the hospital for re-examination 1 and 3 months after discharge, with a statistically significant difference ( t=3.14, 7.25, both P<0.05). The experimental group was hospitalized for (11.78 ± 1.17) days, which was showter than (13.74 ± 1.63) days in the control group, with a statistically significant difference ( t=4.68, P<0.05). No respiratory training-related adverse events occurred in both groups of children during hospitalization. During home respiratory training after discharge, 1 and 2 respiratory training-related adverse events occurred in the experimental group 1 and 3 months after discharge, respectively, compared with 6 and 9 in the control group. The difference was statistically significant ( χ2=4.64, 5.94, both P<0.05). Conclusions:Early respiratory training solutions based on the 4E mode can improve the clinical symptoms of BO children, shorten the hospitalization time, reduce the number of adverse events related to respiratory training, and promote the recovery of children.

Hemodynamic responses during inspiratory muscle exercise in healthy young adults / Respuestas hemodinámicas durante el ejercicio de los músculos inspiratorios en adultos jóvenes sanos / Respostas hemodinâmicas durante exercício muscular inspiratório em jovens saudáveis

ABSTRACT The literature on hemodynamic responses during inspiratory muscle exercise (IME) lacks a consensus. To evaluate and compare hemodynamic responses during an IME session with and without resistive load, 15 sedentary men were subjected to two randomized IME sessions: one with 40% of maximal inspiratory pressure (IME 40%) and another without a resistive load (Sham), both of which were performed for two minutes over eight sessions with one-minute intervals. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), total peripheral resistance (TPR), stroke volume (SV), cardiac output (CO), and heart rate (HR) were measured by infrared digital photoplethysmography during five basal minutes and during the IME sessions. One-way analysis of variance and the Student's t test for paired data were used to analyze hemodynamic response and delta values between sessions. Effect size was evaluated by Cohen's D. A 5% significance level was adopted. SBP responses (sham: ∆−1±2 vs. 40%: ∆−4±2mmHg, p=0.27), DBP (sham: ∆2±1 vs. 40%: ∆1±2mmHg, p=0.60) and MBP (sham: ∆2±1 vs. 40%: ∆0±2mmHg, p=0.28) were similar between sessions. HR increases were higher in the 40% IME session than in the sham session (sham: ∆9±2 vs. 40%: ∆3±2bpm, p=0.001). SV only decreased during the sham session but responses were similar between sessions (sham: ∆−2±2 vs. IME 40%: ∆−6±2ml, p=0.13). Both sessions did not change SBP, DBP, MBP, CO, and TPR, but we observed a greater increase in HR in the IME 40% session. Only the Sham session decreased SV.

RESUMEN No hay consenso en la literatura sobre las respuestas hemodinámicas durante el ejercicio muscular inspiratorio (EMI). El objetivo de este estudio fue evaluar y comparar las respuestas hemodinámicas durante una sesión de EMI con y sin carga resistiva. Para ello, quince hombres sedentarios recibieron dos sesiones aleatorias de EMI: el 40% de la presión inspiratoria máxima (EMI 40%) y sin carga resistiva (sham), realizadas durante dos minutos, ocho sesiones y a intervalos de un minuto. La presión arterial sistólica (PAS), la presión arterial diastólica (PAD), la presión arterial media (PAM), la resistencia periférica total (RPT), el volumen sistólico (VS), el gasto cardíaco (GC) y la frecuencia cardíaca (FC) se midieron mediante fotopletismografía infrarroja digital durante cinco minutos al inicio y durante las sesiones de EMI. Se utilizaron ANOVA unidireccional y la prueba t de Student a datos emparejados para analizar la respuesta hemodinámica y los valores delta entre las sesiones. El tamaño del efecto se evaluó por el d de Cohen. El nivel de significancia adoptado fue de 5%. Las respuestas de PAS (sham: Δ−1±2 vs. 40%: ∆−4±2mmHg, p=0,27), PAD (sham: ∆2±1 vs. 40%: ∆1±2mmHg, p=0,60) y PAM (sham: ∆2±1 vs. 40%: ∆0±2mmHg, p=0,28) fueron similares entre las sesiones. El incremento de la FC fue mayor en la sesión de EMI 40% comparada con la sesión sham (sham: Δ9±2 vs. 40%: ∆3±2bpm, p=0,001). El VS tuvo una disminución exclusiva durante la sesión sham, pero la respuesta fue similar entre las sesiones (sham: Δ−2±2 vs. EMI 40%: ∆−6±2ml, p=0,13). Ambas sesiones no tuvieron cambios en las variables PAS, PAD, PAM, DC y RPT, pero se observó un mayor incremento de la FC en la sesión EMI 40%. Solamente en la sesión sham hubo una reducción del VS.

RESUMO A literatura carece de um consenso sobre respostas hemodinâmicas durante o exercício muscular inspiratório (EMI). Este estudo buscou avaliar e comparar as respostas hemodinâmicas durante uma sessão de EMI com e sem carga resistiva. Para tanto, 15 homens sedentários foram submetidos a duas sessões randomizadas de EMI: 40% da pressão inspiratória máxima (EMI 40%) e sem carga resistiva (sham), realizadas por dois minutos em oito sessões e com intervalos de um minuto. A pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), pressão arterial média (PAM), resistência periférica total (RPT), volume sistólico (VS), débito cardíaco (DC) e frequência cardíaca (FC) foram medidos por fotopletismografia infravermelha digital por cinco minutos basais e durante as sessões de EMI. Anova de uma via e o teste t de Student para dados pareados foram usados para analisar a resposta hemodinâmica e os valores delta entre as sessões. O tamanho do efeito foi avaliado pelo d de Cohen. Adotou-se nível de significância de 5%. As respostas de PAS (sham: ∆−1±2 vs. 40%: ∆−4±2mmHg, p=0,27), PAD (sham: ∆2±1 vs. 40%: ∆1±2mmHg, p=0,60) e PAM (sham: ∆2±1 vs. 40%: ∆0±2mmHg, p=0,28) foram semelhantes entre as sessões. Os aumentos da FC foram maiores na sessão de EMI 40% do que nas sessões sham (sham: ∆9±2 vs. 40%: ∆3±2bpm, p=0,001). O VS diminuiu exclusivamente durante a sessão sham mas a resposta foi semelhante entre as sessões (sham: ∆−2±2 vs. EMI 40%: ∆−6±2ml, p=0,13). Ambas as sessões não causaram alteração nas variáveis PAS, PAD, PAM, DC e RPT, mas notamos um aumento maior da FC na sessão EMI 40%. Apenas a sessão sham reduziu o VS.

Ventilatory Muscle Strength Six Months After Coronary Artery Bypass Grafting in Patients Submitted to Inspiratory Muscular Training Based on Anaerobioc Threshold: A Clinical Trial

Abstract Introduction Coronary artery bypass grafting (CABG) surgery is associated with a decline in ventilatory muscle strength and lung function. Inspiratory muscle training (IMT) based on anaerobic threshold (AT) has been used to minimize the impact of CABG on these parameters, but the long-term impact is unknown. Objective To test the hypothesis that AT-based IMT improves inspiratory muscle strength and lung function even six months after CABG. Methods This is a randomized controlled clinical trial. In the preoperative period, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), vital capacity (VC) and peak expiratory flow (PEF) rate were assessed. On the first postoperative day, patients were randomized into two groups: AT-based IMT (IMT-AT) (n=21) where the load was prescribed based on glycemic threshold and conventional IMT (IMT-C) (n=21), with load of 40% of MIP. Patients were trained during hospitalization until the day of discharge and were assessed at discharge and six months later. For within-group comparison, paired Student's t-test or Wilcoxon test was used, and independent Student's t-test or the Mann-Whitney test was used to analyze the different time points. A p<0.05 was considered significant. Results At six months after CABG surgery, statistical difference was found between the IMT-AT and the IMT-C groups in MIP (difference between the means of -5cmH2; 95% CI=- 8.21to-1.79) and VC (difference between the means of -2ml/kg;95%CI=-3.87to-0.13). No difference was found between groups in the other variables analyzed. Conclusion IMT-AT promoted greater recovery of inspiratory muscle strength and VC after six months of CABG when compared to conventional training.

Objective: To evaluate the effects of Liu Zi Jue Qigong (LQG)-based breathing training on the curvature and range of motion (ROM) of the thoracic and lumbar spines in different positions. Methods: Forty-seven college students were selected as subjects and randomly divided into an observation group and a control group. In the observation group, 27 subjects received regular LQG-based breathing training for 12 weeks, while 20 subjects in the control group did not receive any intervention. The spine measuring instrument Spinal Mouse was adopted to detect the curvature and ROM of the thoracic and lumbar spines. Results: In the observation group, the changes in the curvatures of thoracic spine in the upright and forward-bending positions showed statistical significance after LQG exercise (P<0.05), while there was no notable difference in the control group. The comparison of ROM of the thoracic spine from the upright position to the forward-bending and load-bearing positions showed statistically significant difference in the observation group (P<0.05), while there was no significant difference in the control group. There was no significant difference in the lumbar curvature and ROM in the two groups after LQG exercise. Conclusion: LQG-based breathing training improves the curvature and ROM of the thoracic spine.

Efetividade de diferentes protocolos e cargas utilizadas no treinamento muscular inspiratório de indivíduos com DPOC: uma revisão sistemática / Eficacia de diferentes protocolos y cargas utilizadas en el entrenamiento muscular inspiratorio de personas con EPOC: una revisión sistemática / Effectiveness of different protocols and loads used in inspiratory muscle training of individuals with COPD: a systematic review

RESUMO A doença pulmonar obstrutiva crônica (DPOC) provoca alterações no sistema musculoesquelético, afetando inclusive os músculos respiratórios e levando ao aumento da dispneia e à redução da capacidade funcional. Nesse sentido, o treinamento muscular inspiratório (TMI) deve fazer parte do programa de reabilitação pulmonar. Diversos estudos já demonstraram sua eficácia, contudo, ainda é necessário investigar qual a melhor forma de realizá-lo. Assim, o objetivo deste estudo foi investigar por meio de uma revisão sistemática a efetividade de diferentes protocolos e cargas de TMI sobre os desfechos de força e resistência dos músculos inspiratórios, bem como de capacidade funcional e redução da dispneia. Trata-se de uma revisão sistemática realizada de acordo com o protocolo PRISMA. A busca foi realizada em fevereiro de 2021, nas seguintes bases de dados: PubMed, SciELO, PEDro. Para a busca dos artigos, os seguintes descritores foram empregados: "COPD"; e "breathing exercises, resistive training, respiratory muscle training". Um total de 398 pacientes foram incluídos nos 10 estudos selecionados, todos previamente diagnosticados com DPOC. Foram utilizados diferentes dispositivos para o TMI, e os protocolos variaram em relação às cargas e progressão. O dispositivo mais utilizado entre os artigos foi o Threshold, com carga estabelecida de acordo com a porcentagem da pressão inspiratória máxima (30-80%), reajustada de acordo com novas medições a cada uma ou duas semanas. Houve semelhança de resultados positivos encontrados tanto em treinamentos com cargas baixas quanto com cargas altas, havendo uma melhora na força muscular inspiratória, capacidade funcional e dispneia. No entanto, mais estudos são necessários para definir o melhor protocolo de TMI para DPOC.

RESUMEN La enfermedad pulmonar obstructiva crónica (EPOC) produce cambios en el sistema musculoesquelético, incluidos los músculos respiratorios, lo que provoca un aumento de la disnea y reducción de la capacidad funcional. En este sentido, el entrenamiento de la musculatura inspiratoria (EMI) debe formar parte del programa de rehabilitación pulmonar. Varios estudios ya reportaron su eficacia, pero todavía es necesario investigar la mejor manera de realizarlo. Por lo tanto, el objetivo de este estudio fue investigar, basándose en una revisión sistemática, la efectividad de diferentes protocolos y cargas de EMI en los resultados de fuerza y resistencia de la musculatura inspiratoria, así como en la capacidad funcional y la reducción de la disnea. Esta es una revisión sistemática que siguió el protocolo PRISMA. Se realizó una búsqueda de datos en febrero de 2021 en las siguientes bases de datos: PubMed, SciELO y PEDro. Para estas búsquedas se utilizaron los siguientes descriptores: "COPD" y "breathing exercises, resistive training, respiratory muscle training". Un total de 398 pacientes se incluyeron en los 10 estudios seleccionados, y todos los participantes habían recibido diagnóstico previo de EPOC. Se utilizaron diferentes dispositivos para EMI, y los protocolos variaron con relación a cargas y progresión. Entre los artículos, la herramienta más utilizada fue Threshold, con carga según el porcentaje de presión inspiratoria máxima (30-80%), reajustada conforme nuevas medidas cada una o dos semanas. Se encontraron resultados positivos similares en el entrenamiento con bajas cargas y en el con altas cargas, con mejora de la fuerza de la musculatura inspiratoria, de la capacidad funcional y de la disnea. Sin embargo, se necesitan más estudios para definir el mejor protocolo de EMI para EPOC.

ABSTRACT Chronic obstructive pulmonary disease (COPD) changes the musculoskeletal system, including the respiratory muscles, which are responsible for increasing dyspnea and reducing functional capacity. Several studies have already showed the effectiveness of inspiratory muscle training (IMT); therefore, it should be part of the pulmonary rehabilitation program. However, assessing the best way to do it is still necessary. Thus, this study aimed to evaluate, by a systematic review, the effectiveness of different IMT protocols and loads on the outcomes of inspiratory muscle strength and endurance, functional capacity, and dyspnea reduction. This systematic review was performed in accordance with the PRISMA protocol. Studies were searched in February 2021 in the PubMed, SciELO, PEDro. For the search, the following keywords were used: "COPD" and "breathing exercises, resistive training, respiratory muscle training." A total of 398 individuals previously diagnosed with COPD were included in the 10 selected studies. Different IMT devices were used and protocols varied in relation to loads and progression. Threshold was the most used IMT device. Its load was established according to the percentage of maximal inspiratory pressure (MIP) (30-80%) and readjusted according to new measurements taken every one or two weeks. Respiratory muscle training with both low loads and high loads presented positive results, however, establishing which is the best IMT protocol for individuals with COPD is not possible yet. Inspiratory muscle strength, functional capacity, and dyspnea get better with IMT.

Telematics program of breathing exercises and mindfulness for post-coronavirus disease 2019 patients

SUMMARY OBJECTIVE: The coronavirus disease 2019 pandemic is an economic, social, and health challenge. During the coronavirus disease 2019 lockdown, a telematics platform for respiratory physiotherapy and mindfulness was created, aiming to reduce dyspnea and anxiety and to increase quality of life in post-coronavirus disease 2019 patient. METHODS: A quasi-experimental study was performed on post-coronavirus disease 2019 patients, with breathing exercises and mindfulness with remote supervision by a respiratory physiotherapist. Dyspnea on exertion (Mahler Scale), quality of life (EuroQol-5D score), and anxiety (State-Trait Anxiety Inventory questionnaire) were measured before and after the rehabilitation program. RESULTS: A total of 20 subjects completed the program, with a significant decrease in the measures of dyspnea on exertion (p<0.001), state anxiety (p=0.004), and trait anxiety (p=0.001) and a significant increase in quality of life (p=0.016). CONCLUSIONS: Coronavirus disease 2019 should be treated using a multidisciplinary approach that includes respiratory rehabilitation. At present, there are few studies on respiratory rehabilitation and mindfulness in post-coronavirus disease 2019 patients. The results of this study showed that the implementation of breathing exercises and mindfulness with remote supervision was effective in decreasing dyspnea and anxiety and in increasing quality of life in post-coronavirus disease 2019 patients during confinement.

To explore the clinical efficacy and possible mechanism of Tai Ji Quan for post-stroke depression (PSD), literature related to Tai Ji Quan and PSD were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full- text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), and PubMed, screened and then summarized. The results showed that Tai Ji Quan could effectively improve the depression and quality of life of stroke patients, and there were differences in the clinical efficacy among different training programs. Tai Ji Quan has the characteristics of "regulating mind", "regulating breath", and "regulating body". It may achieve the effect of "combined physique-spirit treatment" by improving social psychology, increasing the level of neurotrophin, regulating neuroendocrine, reducing inflammatory factors, and regulating neural circuits.

Entrenamiento muscular inspiratorio en pacientes con insuficiencia cardíaca: una revisión de revisiones / Inspiratory muscle training in patients with heart failure: a review of reviews

RESUMEN: El objetivo de esta revisión fue conocer la influencia del entrenamiento muscular inspiratorio (EMI) sobre la capacidad aeróbica y la fuerza muscular inspiratoria (FMI) en pacientes con insuficiencia cardíaca (IC). Realizamos una revisión de revisiones sistemáticas en PubMed y Web of Science hasta agosto de 2019. Se identificaron un total de 2053 artículos, de los cuales 4 se seleccionaron para esta revisión. Se utilizó la herramienta 'Assessment of Multiple Systematic Reviews 2' (AMSTAR-2) para evaluar la calidad de los estudios. En los estudios incluidos se examinaron un total de 10 intervenciones diferentes con 250 pacientes (rango edad media= 53-76 años). Todos los estudios presentaron nivel de confianza alto (AMSTAR-2). El EMI presentó mejoras significativas sobre la capacidad aeróbica (test de la marcha de 6 minutos: 46.66-71.04 metros; p<0.05 y VO2pico: 2.59-2.65 mL/kg-1/min-1; p<0.01) y la FMI (presión inspiratoria máxima: 16.57-23.36 cmH2O, p<0.05) en comparación al grupo control. Programas de intervención de EMI con una duración de 12 semanas reportaron mayores mejorías sobre la capacidad aeróbica y la FMI en comparación a programas de intervención de menor duración. El EMI es un tratamiento importante y necesario en la rehabilitación cardíaca de pacientes con IC. Son necesarios más estudios que analicen los efectos de diferentes rangos en las características del EMI.

ABSTRACT: The aim of this review was to understand the influence of inspiratory muscle training (IMT) on aerobic capacity and inspiratory muscle strength (IMS) in patients with heart failure (HF). We conducted a review of systematic reviews in PubMed and Web of Science up to August 2019. A total of 2053 articles were identified, of which 4 were selected for this review. The 'Assessment of Multiple Systematic Reviews 2' (AMSTAR-2) tool was used to assess the quality of the studies. In the included studies, a total of 10 different interventions with 250 patients (mean age range = 53-76 years) were examined. All the studies presented high confidence level (AMSTAR-2). IMT showed significant improvements in aerobic capacity (6-minute walk test: 46.66-71.04 meters; p<0.05 and VO2peak: 2.59-2.65 mL/kg-1/min-1; p<0.01) and IMS (maximal inspiratory pressure: 16.57-23.36 cmH2O, p<0.05) in this population compared to the control group and IMF in this population. IMT intervention programs lasting 12 weeks reported greater improvements in aerobic capacity and IMS compared to shorter intervention programs. IMT is an important and necessary treatment in cardiac rehabilitation of patients with HF. More studies are needed to analyze the effects of different ranges of the IMT characteristics.

Protocol-optimizing study of combining Tuina and horse-riding squat exercise for knee osteoarthritis / 针灸推拿医学（英文版）

Objective: To evaluate the efficacy of Tuina (Chinese therapeutic massage) manipulation plus horse-riding squat exercise in treating knee osteoarthritis (KOA) and optimize the combining protocol. Methods: Based on a 2×2 factorial design, 120 eligible KOA patients were randomized into a manipulation group (group A1B2), a manipulation plus horse-riding squat group (group A1B1), a sitting knee-adjustment group (group A2B2 group), and a sitting knee-adjustment plus horse-riding squat group (group A2B1), with 30 cases in each group. The intervention was conducted three times a week, lasting for four weeks. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) was taken as the major measure for efficacy evaluation (including three component scores, pain, stiffness, and daily function, and total score). Results: The three component scores (pain, stiffness, and daily function) and the total score of WOMAC showed significant differences after the intervention in the four groups (P<0.05). There were significant inter-group differences in the WOMAC stiffness score amongst the four groups after the intervention (P<0.05). In group A1B1, the step length, stride, walking speed, and knee joint flexion angle changed significantly after treatment (P<0.05). After the intervention, the step length changed significantly in group A1B2 (P<0.05), and the walking speed changed significantly in group A2B1 (P<0.05). There were no significant differences in the step length, stride, walking speed, or knee joint flexion angle among the four groups (P>0.05). The extensor peak torque at 180 °/s changed significantly in group A1B2 after treatment (P<0.05). Neither the intra-group nor the inter-group comparisons of the four groups revealed significant differences in the other isokinetic muscle strength parameters (P>0.05). The main effect of manipulation showed significant in affecting the WOMAC pain and total scores (P<0.05). The main effect of horse-riding squat exercise showed significant in affecting the WOMAC pain and stiffness scores (P<0.05). Conclusion: The four treatment protocols all can improve the symptoms of KOA, for instance, relieving pain and stiffness, and enhancing daily function. Group A2B1 produces the most eminent effect in relieving joint stiffness. The main effects of both manipulation and horse-riding squat exercise are significant in reducing pain. Besides, the main effect of horse-riding squat exercise is significant in relieving joint stiffness.

Increased Maximal Expiratory Pressure, Abdominal and Thoracic Respiratory Expansibility in Healthy Yoga Practitioners Compared to Healthy Sedentary Individuals

Abstract Background Increasing thoracic expansion is effective at reducing blood pressure in hypertensive subjects. Yoga prescribes many respiratory techniques with a growing number of practitioners. However, very little is known whether sedentary or yoga practitioners show measurable differences in their respiratory patterns. Objective This study aims to demonstrate differences between healthy sedentary individuals and healthy yoga practitioners regarding maximal respiratory pressures and thoracic and abdominal respiratory expansibility. Methods Maximal inspiratory and expiratory pressures (MIP and MEP, respectively) were evaluated by manovacuometry, while respiratory expansion was assessed by the cirtometry of abdominal (CA), thoracic xiphoidal (CTX), and thoracic axillary (CTA) circumferences at rest (end expiratory moment) and at full inspiration in healthy sedentary individuals (SED) and yoga practitioners (YOGA). A delta derived from rest and full inspiration measures (ΔCA, ΔCTX, and ΔCTA, respectively), followed by a percentage of each item (ΔCA/CA, ΔCTX/CTX, and ΔCTA/CTA) was then calculated. Groups were compared by means of an unpaired Student's t-test, with a significance level p < 0.05. Results All respiratory expansion measures were significantly higher in in the YOGA group. A significantly higher MEP (cmH2O) was also detected in yoga practitioners: SED 89.3 ± 19.3 and YOGA 114.7 ± 24.8 ( p = 0.007), along with decreased heart rate at rest (bpm): SED 84±6 and YOGA 74±15 ( p = 0.001). Conclusions Yoga practitioners have shown greater thoracic and abdominal expansion and increased MEP, when compared to healthy sedentary individuals, as well as significantly lower heart rates at rest and body mass index (BMI). However, whether or not these findings are related to respiratory patterns is uncertain.

Pulmonary rehabilitation for COVID-19: a living systematic review protocol

Objective This living systematic review aims to provide a timely, rigorous and continuously updated summary of the evidence available on the role of pulmonary rehabilitation in the treatment of patients with COVID-19. Design This is the protocol of a living systematic review. Data sources We will conduct searches in the L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that maps PICO questions to a repository maintained through regular searches in electronic databases, preprint servers, trial registries and other resources relevant to COVID-19. No date or language restrictions will be applied. Eligibility criteria for selecting studies and methods We adapted an already published common protocol for multiple parallel systematic reviews to the specificities of this question. We will include randomized trials evaluating the effect of pulmonary rehabilitation as monotherapy or in combination with other interventions-versus sham or no treatment in patients with COVID-19. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will pool the results using meta-analysis and will apply the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to assess the certainty of the evidence for each outcome. Ethics and dissemination No ethics approval is considered necessary. The results of this review will be widely disseminated via peer-reviewed publications, social networks and traditional media.
