In this quasi-experimental before-after trial, we investigated the effects of a high-intensity, low-repetition inspiratory muscle training (HI-LRMT) protocol on respiratory muscle strength in instrumental musicians. In addition, was to estimate the prevalence of “non-responders” (NRs) in terms of muscle force after intervention. Healthy musicians (n = 48) were divided into 2 groups: HI-LRMT (n = 33) and a control group that did not train (CG, n = 15). The intervention training was a high-intensity, low-repetition inspiratory muscle training program using the PowerBreathe® threshold load pressure device, 2 daily sessions of 30 repetitions per session, with a minimum frequency of 5 days per week, for 12 weeks, 5 min per session. The primary outcome measures were maximal inspiratory pressure and expiratory pressure. Change in PImax over 12 weeks for HI-LRMT vs. control was 30.9 (95% CI 25.5–38.3), with the large effect, confirming worthwhile benefits (ηp2 = 0.61). There were significant changes in PEmax 37.3 (95% CI 19.3–48.1), with a large effect size (ηp2 = 0.33). A third of the participants did not demonstrate improvements in terms of muscle force in instrumental musicians. In conclusion, a 12-week high-intensity, low-repetition inspiratory muscle training program using the PowerBreathe® threshold load pressure device, improved inspiratory and expiratory muscle strength in instrumental musicians.

Background: An inspiratory capacity to total lung capacity (IC/TLC) ratio of ≤25% has emerged as a better marker of mortality in chronic obstructive pulmonary disease (COPD) patients. The relationship among the IC/TLC ratio to lower extremity skeletal muscle function remains unknown. Methods: Thirty-five men with moderate to severe COPD were divided into those with IC/TLC ≤ 25% (n = 16) and >25% (n = 19). The subjects were tested for thigh muscle mass volume (MMT), maximal strength, power output of the lower extremities, and physical activity. Results: Total MMT in the IC/TLC < 25% group was significantly lower (413.91 ± 89.42 cm3) (p < 0.001) than in the IC/TLC > 25% group (575.20 ± 11.76 cm3). In the IC/TLC ≤ 25% group, maximal strength of the lower extremities and muscle peak power output of the lower extremities were 36---56% lower (p < 0.01) than among the patients in the IC/TLC > 25% group. Conclusion: IC/TLC ≤ 25% is associated with reduced maximal strength and peak power output of the lower extremities. IC/TLC ≤ 25% may have an important clinical relevance as an index to determine peripheral muscle dysfunction.

(Lippincott, Williams & Wilkins (LWW), 2015) Zambom Ferraresi, Fabrício; Gorostiaga Ayestarán, Esteban; Hernández, María; Hueto, Javier; Cascante, José; Rezusta, Lourdes; Val, Luis; Antón Olóriz, María Milagros; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
PURPOSE: To compare the effects of 12-week training periods (2 d·wk¯¹) involving resistance training only with the effects of 12-week training periods involving combined resistance (once weekly) and endurance (once weekly) training on strength, endurance performance, and quality of life. METHODS: Thirty-six patients with moderate-to-severe chronic obstructive pulmonary disease were randomized to combined training (REG), resistance training alone (RG), or control (CG) groups. Patients were tested for maximal strength of the upper and lower extremities, power output of the lower extremities, maximal (Wmax) and submaximal exercise capacity, performance on a 6-minute walk test (6MWT), and quality of life. RESULTS: REG and RG induced similar maximal strength gains. Muscle power increased 19% (P ≤.01) and Wmax improved 13% (P < .05) in REG. Reductions (P < .05) in the heart rate and blood lactate at a given submaximal workload were observed in REG. Improvements in 6MWT and quality of life were similar in both training groups. CONCLUSIONS: Compared with a twice-weekly resistance training program, the combination of once-weekly resistance and once-weekly endurance training not only produced similar gains in maximal strength, 6MWT performance, and quality of life but also produced improvements in muscle power and endurance performance. These findings may have implications for the prescription of resistance and endurance exercise for patients with chronic obstructive pulmonary disease.

Efectos de realizar actividad física en la función muscular en EPOC
(Universidad Autonoma de Madrid y Comunidad Virtual Ciencias del Deporte, 2021) Cebollero Rivas, Pilar; Zambom Ferraresi, Fabrício; Hueto, Javier; Cascante Rodrigo, José Antonio; Antón Olóriz, María Milagros; Ciencias de la Salud; Osasun Zientziak
El objetivo de este estudio fue examinar los efectos de un programa de actividad física (AF) de andar en la función muscular en pacientes con EPOC (Enfermedad Pulmonar Obstructiva Crónica), con un seguimiento de 12 meses. Se reclutaron 44 hombres (70,3 ± 6,7 años) diagnosticados de EPOC moderado-severo. El grupo intervención realizó un programa de actividad física (GAF) y el grupo control (GCO) siguió su tratamiento estándar. Se midió la fuerza máxima (1RM) del miembro inferior y superior, la potencia muscular del miembro inferior (50% y 70% 1RM) y la actividad física, antes y después de 12 meses. A los 12 meses, incremento un 8% (P<0,01) la 1RM del miembro inferior en GAF, sin cambios en GCO. La potencia muscular al 50%1RM incrementó un 12% en GAF, disminuyendo un 9% in GCO (P<0,05). Un programa de AF incrementa la fuerza y preserva la potencia muscular del miembro inferior.

(Sociedade Brasileira de Pneumologia e Tisiologia, 2017) Zambom Ferraresi, Fabrício; Cebollero Rivas, Pilar; Hueto, Javier; Antón Olóriz, María Milagros; Ciencias de la Salud; Osasun Zientziak
Objective: To evaluate a 24-month supervised, community-based maintenance exercise program after 3 months of pulmonary rehabilitation (PR) in comparison with a 27-month physical activity counseling program, in terms of the effects on maximal muscle strength, muscle power output, and exercise capacity, in individuals with COPD. Methods: Sixty-three men with moderate-to-severe COPD were recruited from two previous studies. Of those 63 participants, 31 were offered 3 months of PR followed by a 24-month supervised maintenance exercise program (24MME group) and 32 were offered a 27-month physical activity counseling program (27MPAC group). Measurements at 3 months and at the end of the study period included maximal strength of the upper and lower limbs, power output of the lower limbs, six-minute walk distance (6MWD), and quality of life. Results: At 27 months, the improvements in maximal strength of the upper and lower limbs were greater in the 24MME group than in the 27MPAC group (37.6 ± 28.3% and 28.4 ± 13.3%, respectively, vs. 8.8 ± 16% and 13.6 ± 16.4%, respectively; p < 0.05), as was the improvement in power output of the lower limbs (24.6 ± 18.4% vs. −2.3 ± 28.5%; p < 0.01). The increase in the 6MWD after 3 months was also greater in the 24MME group than in the 27MPAC group (33.2 ± 36.6 m vs. 2.9 ± 34.7 m; p < 0.05), although there were no differences between the two groups in terms of the Δ6MWD at 27 months (vs. baseline). Conclusions: A supervised, community-based maintenance program is a successful long-term strategy to preserve the benefits of PR on peripheral muscle function and exercise capacity in individuals with COPD. However, physical activity counseling can maintain maximal muscle strength and exercise capacity in such individuals.

Assessment of dyspnea and dynamic hyperinflation in male patients with chronic obstructive pulmonary disease during a six minute walk test and an incremental treadmill cardiorespiratory exercise test
(Elsevier, 2017) Alfonso Imízcoz, María; Bustamante, V.; Cebollero Rivas, Pilar; Antón Olóriz, María Milagros; Herrero, S.; Ciencias de la Salud; Osasun Zientziak
The six minute walk test (6MWT) is a standardized test that provides information on exercise capacity in patients with COPD. It is considered a submaximal test in opposition to incremental cardiopulmonary exercise tests (CPET) that provide valuable information on all the systems involved in exercise. Objectives: 1. To compare the perceptive, physiological responses and degree of dynamic hyperinflation during two exercise tests: the 6MWT and the incremental CPET on a treadmill. 2. To evaluate how dyspnea is related to dynamic hyperinflation (DH) and other functional parameters in both tests. Methods: 29 stable COPD male patients, age 68 ± 5.8 years, mean post-bronchodilator FEV1 57 ± 11%, were recruited. To evaluate dynamic hyperinflation, inspiratory capacity (IC) was measured at rest and upon completing each one of the tests. At the same time, perceived dyspnea and leg discomfort were rated on specific modified Borg scales. Results: The mean walk distance in 6MWT was 494 ± 88 m. The Borg scale rating for shortness of breath upon completing the test was 4.7 ± 2, whilst 2.9 ± 2 for leg discomfort. IC changed from 2.53 ± 0.63 l before to 2.34 ± 0.60 l after completion of the test. In the treadmill CPET, maximal oxygen consumption (VO˙ 2 max) was 21.8 ± 5 mL/kg/min with 6.6 ± 2 dyspnea and 4.3 ± 2 leg discomfort on Borg scales. IC changed from 2.17 ± 0.53 l to 1.20 ± 0.43 l. Conclusions: Dynamic hyperinflation occurs in male COPD patients during submaximal exercise such as the 6MWT. This phenomenon is more pronounced after incremental CPET on a treadmill. Despite being dyspnea the dominant limiting symptom for both tests, we observed different physiological responses.
