“…The most intensively researched aspect of nutrition in relation to its effects on muscle strength and mass is protein/amino acids (3) , both to address the need for amino acids for protein synthesis as well as recognition of a blunted anabolic response to protein consumption in older age, such that protein requirements may need to be higher in older populations (11,12) . There is now a large body of evidence from intervention studies that evaluate the effects of protein supplementation on muscle strength and mass, although to date, findings have been mixed (14) .…”

“…The benefits of progressive resistance exercise training, to increase muscle strength and mass, are clearly established, either alone (9) or in combination with nutritional supplementation (10) . In comparison, although nutrition was shown to be a key field of research in a recent bibliometric analysis of the most highly cited papers on sarcopenia (3) , the evidence that links differences in habitual diets to the risk of development of sarcopenia (11) , or showing the effectiveness of dietary change as a prevention or treatment strategy, is incomplete (12) . There is a need for new research to improve the understanding of the influences of diet and nutrition on the losses of muscle strength and mass that lead to sarcopenia (13) .…”

“…Sarcopenia is a progressive skeletal muscle disorder that is characterised by loss of muscle strength and mass (1) . First described by Rosenberg in 1989, it has generated huge research interest in the decades since (1)(2)(3) leading to progress in its definition and diagnosis, using agreed thresholds for low muscle strength and mass, and impairments in physical performance (4) . Sarcopenia is now recognised as an independent condition; its International Classification of Diseases-10 code was assigned in 2016 (2) .…”

Micronutrients and sarcopenia: current perspectives

Sarcopenia, a skeletal muscle disorder that is characterised by loss of muscle strength and mass, is common in older populations and associated with poorer health outcomes. Although the individual and economic costs of sarcopenia are widely recognised, current understanding of its pathophysiology is incomplete, limiting efforts to translate research evidence into effective preventive and treatment strategies. While nutrition is a key field of sarcopenia research, the role of differences in habitual diets, and the effectiveness of dietary change as a prevention or treatment strategy, is uncertain. There is a growing evidence base that links low micronutrient intakes to sarcopenia risk and/or its components (low muscle strength and mass, impaired physical performance), although there remain many gaps in understanding. There is some consistency in findings across studies highlighting potential roles for antioxidant nutrients, B vitamins and magnesium; however, the evidence is largely observational and from cross-sectional studies, often describing associations with different muscle outcomes. As low intakes of some micronutrients are common in older populations, there is a need for new research, particularly from well-characterised prospective cohorts, to improve the understanding of their role and importance in the aetiology of sarcopenia and to generate the evidence needed to inform dietary guidelines to promote muscle health.

“…En abril de 2010 los grupos de trabajo sobre caquexia y sobre nutrición en geriatría de la European Society for Clinical Nutrition (ESPEN), intentando actualizar la definición de caquexia, intentó definir también los conceptos limítrofes de precaquexia y sarcopenia (12). Ese mismo mes, el European Working Group on Sarcopenia in Older People (EWGSOP), promovido por las sociedades europeas de geriatría y nutrición clínica, entre otras, publicaron una definición conceptual y operativa de la sarcopenia que ha sido la más utilizada y citada en todo el mundo desde entonces, considerándose por el momento la definición de referencia (8,13). Un año después, el International Working Group on Sarcopenia (IWGS), formado por investigadores europeos y estadounidenses, propuso una definición muy similar a la del EWGSOP (14); y en las mismas fechas otro grupo euroestadounidense promovido por la Society on Sarcopenia, Cachexia and Wasting Disorders (SSCWD) propuso el término sarcopenia con movilidad limitada, siendo el único grupo que seguía usando la palabra sarcopenia para describir solamente la masa muscular (15) (17).…”

Las enfermedades musculares estaban infrarrepresentadas en los libros de texto hasta hace pocas décadas, sin considerar la importancia de la masa y las funciones de los músculos esqueléticos y sus cambios relacionados con el envejecimiento. En 1987 se creó el término sarcopenia para definir la pérdida de masa y función del músculo esquelético y sus importantes consecuencias funcionales. Desde entonces su definición ha progresado con los avances de la investigación. En este artículo se revisan los primeros pasos de esta enfermedad, inicialmente definida solamente por la baja masa muscular, mediante la incorporación progresiva de la función muscular y el rendimiento físico. Se describe luego la aparición de varias definiciones de consenso de sarcopenia alrededor de 2010. Estas definiciones demostraron que la sarcopenia aumenta de forma muy significativa la mortalidad, las caídas y la dependencia funcional. Aunque permitieron que la sarcopenia fuera incluida en la clasificación internacional de enfermedades, no lograron que fuera diagnosticada de forma habitual en la práctica clínica. Se revisan por último las actualizaciones de estas definiciones en los últimos dos años, con la intención de que su traslación a la práctica permita empezar a aliviar las graves consecuencias de la sarcopenia.

“…In fact, the main recommendations for sarcopenia management are exercise and nutritional interventions [3,4]. Even though the role of nutrition in the prevention of sarcopenia forms a key field of research [5], extensive studies are still necessary to establish this fact. With respect to the role of nutrients in improving muscle mass and strength, the majority of the studies to date have extensively reported on the functions of proteins and amino acids, followed by vitamin D and omega 3 fatty acids [3,5,6].…”

Satellite Cells Exhibit Decreased Numbers and Impaired Functions on Single Myofibers Isolated from Vitamin B6-Deficient Mice

Emerging research in human studies suggests an association among vitamin B6, sarcopenia, and muscle strength. However, very little is known regarding its potential role at the cellular level, especially in muscle satellite cells. Therefore, to determine whether vitamin B6 affects the satellite cells, we isolated single myofibers from muscles of vitamin B6-deficient and vitamin B6-supplemented mice. Subsequently, we subjected them to single myofiber culture and observed the number and function of the satellite cells, which remained in their niche on the myofibers. Prior to culture, the vitamin B6-deficient myofibers exhibited a significantly lower number of quiescent satellite cells, as compared to that in the vitamin B6-supplemented myofibers, thereby suggesting that vitamin B6 deficiency induces a decline in the quiescent satellite cell pool in mouse muscles. After 48 and 72 h of culture, the number of proliferating satellite cells per cluster was similar between the vitamin B6-deficient and -supplemented myofibers, but their numbers decreased significantly after culturing the myofibers in vitamin B6-free medium. After 72 h of culture, the number of self-renewing satellite cells per cluster was significantly lower in the vitamin B6-deficient myofibers, and the vitamin B6-free medium further decreased this number. In conclusion, vitamin B6 deficiency appears to reduce the number of quiescent satellite cells and suppress the proliferation and self-renewal of satellite cells during myogenesis.
