Adequate dietary protein is associated with better physical performance among post-menopausal women 60–90 years

Abstract: Objectives Sarcopenia, the involuntary loss of skeletal muscle with age, affects up to one-quarter of older adults. Evidence indicates a positive association between dietary protein intake and lean muscle mass and strength among older persons, but information on dietary protein’s effect on physical performance in older adults has received less attention. Design Cross-sectional observational analysis of the relationship of dietary protein on body composition and physical performance. Setting Clinical resear… Show more

“…38 Nevertheless, more research is needed in order to confirm this hypothesis because it is well established that an adequate caloric intake is needed to optimally utilize dietary protein to maintain muscle function rather than as E source. 39 Notwithstanding the importance of our results, this study has several limits. First, its cross-sectional design makes it difficult to assess the temporal relationship between protein intake and frailty.…”

“…On the other side, protein consumption seems to be crucial for bone matrix development and overall bone health, especially in young and elderly subjects (Bonjour 2005;Gaffney-Stomberg et al 2009). Moreover, increase in dietary protein intake has also been correlated to a rise in IGF-I, muscle protein synthesis and physical performance, which are linked to bone status gain and decreased fracture risk (Alexy et al 2005;Heaney & Layman 2008;Gregorio et al 2014).…”

“…Dietary proteins have been proposed as potentially important modifiable factors for maintaining physical performance in older adults (3)(4)(5). However, the effect of protein intake or supplementation on physical performance in elderly individuals at a population level remains to be clarified because inconsistent results have been reported in both cross-sectional (3,6) and longitudinal (4,5,7) studies.…”
