[en] Introduction: Sarcopenia can be defined, according to EWGSOP (European Working Group on Sarcopenia in Older People) criteria, as the loss of strength, mass and muscle function secondary to aging. Furthermore, it is usually associated with an increased risk of falls and fragility fractures. In different reviews, a prevalence of sarcopenia has been recorded between 5-13% in patients older than 60 years, 20% in people older than 70 years and 50% of those older than 80 years, so it represents a major health problem. The interest of this project lies in the increase in life expectancy in people over 65 years of age, which is associated with a greater aging of the population. Therefore, with the aim of improving their quality of life, it would be interesting to carry out a prevention of sarcopenia, or once established, propose a physiotherapy treatment. Objective: To verify if a program of muscular strengthening and cardiovascular resistance improves muscular strength, physical performance and functional status of older adults with sarcopenia. Material and methodology: A single blind randomized controlled study with a sample of 40 over 65 years, diagnosed with sarcopenia, is proposed. They will be divided into two groups, one of them will carry out a therapeutic exercise program based on muscular strengthening and cardiovascular resistance (research group) and the other will not carry out the intervention (control group). Both groups will continue with their usual physical therapy treatment. This intervention will take place over 12 months and will consist of 3 weekly sessions lasting one hour. Pre-intervention, post-intervention and at three months, the variables of sociodemographic data, anthropometric measures, level of physical activity, quality of life, fragility, muscular strength, cardiovascular function, respiratory function, physical performance, perceived effort and risk of falls will be evaluated. Applicability: If the results obtained confirm the alternative hypothesis, the program will show significant results after the intervention period, maintaining the effect during follow-up and these being greater than in the control group. Its impact on participation would represent an advance in the approach to this table and could be extrapolated to other contexts.

[gl] Introdución: A sarcopenia defínese según criterios do EWGSOP (European Working Group on Sarcopenia in Older People) como a perda de forza, masa e función muscular secundaria ao envellecemento. Ademais, asóciase cun aumento do risco de caídas e fracturas por fraxilidade. En diferentes revisións, rexistrouse unha prevalencia de sarcopenia entre o 5-13% en pacientes maiores de 60 anos, do 20% nas persoas maiores de 70 anos e do 50% das maiores de 80 años, polo que representa un importante problema sanitario. O interese deste proxecto radica no incremento da esperanza de vida en maiores de 65 anos que vai asociado cun aumento do envellecemento da poboación. Polo tanto, co obxectivo de mellorar a súa calidade de vida, sería interesante levar a cabo unha prevención da sarcopenia, ou unha vez establecida, plantexar un tratamento fisioterápico. Obxectivo: Comprobar se un programa de fortalecemento muscular e resistencia cardiovascular mellora a forza muscular, o rendemento físico e o estado funcional dos adultos maiores con sarcopenia. Material e metodoloxía: Plantexase un estudo controlado aleatorizado simple cego cunha mostra de 40 maiores de 65 años, diagnosticados de sarcopenia. Dividiranse en dous grupos, un deles realizará un programa de exercicio terapéutico baseado no fortalecemento muscular e na resistencia cardiovascular (grupo experimental) e outro non realizará a intervención (grupo control). Ambos grupos continuarán co seu tratamento de fisioterapia habitual. Esta intervención levarase a cabo durante 12 meses e realizaranse 3 sesións semanais dunha hora de duración. Preintervención, postintervención e aos tres meses, avaliáranse as variables de datos sociodemográficos, medidas antropométricas, nivel de actividade física, calidade de vida, fraxilidade, forza muscular, función cardiovascular, función respiratoria, rendemento físico, esforzo percibido e risco de caídas. Aplicabilidade: Se os resultados obtidos confirman a hipótese alternativa, o programa mostrará resultados significativos tras o período de intervención, manténdose o efecto durante o seguimento e sendo estes maiores que no grupo control. A súa repercusión na participación, supoñería un avance na abordaxe do cadro clínico e podería transferirse a outros contextos.
