RESUMO
Low back pain (LBP) is a health problem that affects 70-80% of the population in Western countries. Because of the biomechanical relationship between the lumbar region and the hip, it is thought that strengthening the muscles of this joint could improve the symptoms of people with LBP. The objective of this study is to evaluate the current evidence on the efficacy of hip strengthening exercises to reduce pain and disability in people with LBP. Clinical trials were collected from the PubMed, PEDro, and Scopus databases published up to September 2022. Based on the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and using CASP and PEDro tools for methodological quality assessment, we selected studies that included hip strengthening exercises as part of LBP treatment and measured pain and/or disability parameters. Among the 966 records identified in the search, a total of 7 studies met the established selection criteria. Overall, participants who performed hip strengthening exercises had significantly improved in pain and disability. The methodological quality of the included studies was assessed as "good". In conclusion, the addition of hip muscle strengthening exercises iterating interacted with LBP, effectively improving pain and disability.
RESUMO
Sports performance in athletes can be limited by respiratory factors, so it is understandable to propose that inspiratory muscle training (IMT) can improve respiratory function and exercise performance. Power-Breathe® (PwB) is a sectorized respiratory muscle training tool that uses a resistive load to train IMT. There is currently a growing interest in respiratory muscle training, so we set out to systematically assess the effects of IMT with PwB on respiratory parameters and athletic performance in physically active, healthy adults. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, the Cochrane and PEDro scales to assess methodological quality, effect size using the Rosenthal formula, and the Cochrane tool for estimation of risk of bias, studies searchable in Medline, Web of Science, and Cochrane. In addition, for the performance of the meta-analysis, the documentation and quantification of the heterogeneity in each meta-analysis were directed through the Cochran's Q test and the I2 statistic; in addition, a publication bias analysis was performed using funnel plots. Of the total of 241 studies identified in the search, 11 studies for the systematic review and nine for the meta-analysis met the exclusion and/or inclusion criteria. IMT, with PwB, showed significant improvements in maximal inspiratory pressure (MIP) and substantial improvements in forced vital capacity (FVC) in the meta-analysis results. Also, sports performance was significantly increased by IMT with PwB. In conclusion, the use of PwB is an IMT tool that improves respiratory and sports performance.
RESUMO
Resumen La enfermedad inflamatoria intestinal (EII) incluye la enfermedad de Crohn (EC) y la colitis ulcerosa (CU). El tratamiento farmacológico en la EII presenta pérdida de eficacia y efectos secundarios, por esta razón es necesario el planteamiento de estrategias alternativas, como la práctica de actividad física (AF), como coadyuvante terapéutico. El propósito de este estudio fue evaluar la efectividad de las intervenciones de AF como herramienta para aumentar la condición física, la calidad de vida relacionada con la salud (CVRS) y mejorar la sintomatología en pacientes con EC y CU, identificando el componente de AF óptimo. Se realizó una revisión mediante una búsqueda en las bases electrónicas de datos Medline (PubMed), SciELO y Cochrane Library Plus, que incluyó ensayos controlados aleatorios de los últimos 10 años que relacionaran la EII y la AF, hasta el 31 de enero de 2022. Se incluyeron 4 estudios con un total de 133 pacientes. La realización de AF de pacientes con EII (CU y EC) aumentó (p>0.05) la capacidad física, la masa muscular esquelética, la densidad mineral ósea y la CVRS, incrementando significativamente (p<0,05) el estado de ánimo. Además, disminuyó significativamente (p<0,05) la inflamación intestinal y las manifestaciones extraintestinales. Se observó una tendencia de reducción (p>0,05) de la fatiga, la tensión arterial y la restauración de la microbiota. La AF moderada y realizada regularmente durante un mínimo de 8 semanas, favorece la mejoría del paciente con EII a nivel físico, psicológico, la CVRS y la sintomatología.
Abstract Inflammatory bowel disease (IBD) includes Crohn's disease (CD) and ulcerative colitis (UC). Pharmacological treatment in IBD presents a loss of efficacy and side effects, inviting to consider alternative strategies, such as the practice of physical activity (PA), as a therapeutic adjuvant. The purpose of this review was to evaluate the effectiveness of PA interventions as a tool to increase physical fitness, and health-related quality of life (HRQoL) and improve the symptomatology in patients with CD and UC, identifying the optimal PA component. The review was performed, by searching the electronic databases Medline (PubMed), SciELO, and Cochrane Library Plus, including randomized controlled trials from the last 10 years that related to IBD and PA, until January 31, 2022. We found four studies with a total of 133 patients. The performance of PA in patients with IBD (UC and CD) increases (p>0.05) physical capacity, skeletal muscle mass, bone mineral density, and HRQoL, significantly (p<0.05) increasing mood. In addition, it significantly (p<0.05) decreases intestinal inflammation and extraintestinal manifestations. A trend of reduction (p>0.05) of fatigue, blood pressure, and microbiota restoration was observed. Moderate PA and performed regularly for a minimum of eight weeks, favors the improvement of the IBD patient at the physical, psychological, HRQoL, and symptomatology levels.
