Estoy traduciendo un metaanálisis sobre recomendaciones de la vitamina D:

"Vitamin D is thought to act on myocyte vitamin D receptors to exert its effect on muscle tissue. In prospective studies, lower serum 25OHD levels have been associated with decreased grip strength and appendicular muscle mass in older men and women. Supplementation with vitamin D has improved lower extremity **muscle performance** and reduced risk of falling in several high-quality double blind randomized controlled trials."

¿Cómo se traduce? ¿Rendimiento muscular? ¿desempeño muscular? Muchas gracias por adelantado
