Background: Myostatin has been proposed as a candidate biomarker for frailty and sarcopenia. However, the relationship of myostatin with these conditions remains inconclusive. Objective: To determine the association of serum myostatin concentration with body composition, physical fitness, physical activity level, and frailty in long-term nursing home residents. We also aimed to ascertain the effect of an exercise program on myostatin levels. Methods: We obtained study data on 112 participants from long-term nursing homes. Participants were randomly assigned to a control or an intervention group and performed a 6-month multicomponent exercise program. Serum myostatin levels were analyzed by ELISA. Assessments also included body composition (anthropometry and bioelectrical impedance), physical fitness (Senior Fitness Test), physical activity level (accelerometry), and frailty (Fried frailty criteria, Clinical Frailty Scale, and Tilburg frailty indicator). Results: The concentration of myostatin at baseline was positively correlated with: a leaner body composition (p < 0.05), and a higher number of steps per day and light and moderate-vigorous physical activity in women (p < 0.005); greater upper and lower limb strength, endurance, and poorer flexibility (p < 0.05) in men; and better performance (less time) in the 8-ft timed up-and-go test in both women (p < 0.01) and men (p < 0.005). We observed higher concentrations of serum myostatin in non-frail than in frail participants (p < 0.05). Additionally, we found that the implemented physical exercise intervention, which was effective to improve physical fitness, increased myostatin concentration in men (p < 0.05) but not in women. The improvements in physical condition were related with increases in serum myostatin only in men (p < 0.05–0.01). Conclusions: Higher serum levels of myostatin were found to be associated with better physical fitness. The improvements in physical fitness after the intervention were positively related to increases in myostatin concentrations in men. These results seem to rule out the idea that high serum myostatin levels are indicative of frailty in long-term nursing home residents. However, although the direction of association was opposite to that expected for the function of myostatin, the use of this protein as a biomarker for physical fitness, rather than frailty, merits further study.

Desenvolveu-se este estudo com três propósitos principais: a) comparar a aptidão física relacionada à saúde (AFRS) entre os rapazes rurais e urbanos; b) verificar se ocorre associação entre o nível de atividade (NAF: inativo, moderadamente ativo, ativo e muito ativo) e a AFRS, por domicílio; c) verificar qual a proporção dos classificados como inativos, moderadamente ativos, ativos e muito ativos que atinge os critérios de referência para uma recomendada AFRS, por domicílio. Mensurou-se 101 rapazes rurais e 130 urbanos, voluntários, com idades entre 17 e 20 anos. O NAF foi estimado através do questionário desenvolvido por Pate (1995), traduzido e adaptado por Nahas (2001). A AFRS foi medida e analisada seguindo a AAHPERD (1988). As variáveis com distribuição normal foram analisadas através da estatística F (p < 0,05) e as sem distribuição normal através do teste de Kruskal-Wallis (p < 0,05). Os resultados obtidos possibilitam concluir que: os rapazes rurais possuem uma AFRS significativamente (p < 0,05) melhor que a dos urbanos; a associação entre o NAF e a AFRS é de baixa magnitude; dos rapazes rurais e urbanos classificados como inativos e moderadamente ativos nulas e/ou mínimas são as proporções deles que atendem os critérios de referência no conjunto dos componentes da AFRS; já, dos classificados como ativos e muito ativos as proporções são maiores, porém não ultrapassando 20%
