    Inspiratory fraction as a marker of skeletal muscle dysfunction in patients with COPD
    (Elsevier, 2017) Cebollero Rivas, Pilar; Zambom Ferraresi, Fabrício; Hueto, Javier; Antón Olóriz, María Milagros; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
    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.

    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.

    Effects of simple long-term respiratory care strategies in older men with COPD
    (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.
