Higher daily protein intake, with an emphasis on leucine content, is thought to mitigate age-related anabolic resistance, potentially counteracting age-related morphological and functional declines. The present study investigated potential associations between total daily leucine intake and dependent variables, including quadriceps muscle cross-sectional area (CSA) and maximum dynamic muscle strength (1-RM) in a cohort of healthy free-living older individuals of both sexes (n = 67; 34/33 men/women). Participants performed three 24 h dietary recalls and underwent a magnetic resonance imaging exam followed by 1-RM tests. Our results demonstrate moderate associations between total daily leucine and both quadriceps CSA (r = 0.42; p = 0.004) and 1-RM (r = 0.45; p = 0.001). Furthermore, our exploratory biphasic linear regression analyses, adjusted for sex, age, and protein intake relative to body weight, revealed a plateau for daily leucine intake and muscle mass and muscle strength (~7.6–8.0 g·day−1) in older adults. In conclusion, we demonstrated that total daily leucine intake is associated with muscle mass and strength in healthy older individuals and this association remains after controlling for multiple factors, including overall protein intake. Furthermore, our breakpoint analysis revealed non-linearities and a potential threshold for habitual leucine intake, which may help guide future research on the effects of chronic leucine intake in age-related muscle loss.

Introduction: Sarcopenia is a prevalent condition, and that is strongly associated with morbimortality outcomes. The optimal way to diagnose sarcopenia is currently a matter of debate. Despite evidence suggesting differences in body composition and physical performance of individuals from different regions, the diagnosis of sarcopenia in Brazil is still conducted using cutoff values established by international consensus. Therefore, the objective of this study was to establish cutoff values for appendicular muscle mass and muscle strength in a population of elderly outpatients with cardiovascular diseases from the city of São Paulo, using this data to compare populations with sarcopenia diagnosed in Brazil with individuals diagnosed using the European consensus values. Materials and Methods: This was a cross-sectional analysis including 502 older individuals from the SARCOS-Brazil study. All subjects underwent densitometry to assess muscle mass and measure strength using a manual dynamometer. The cutoff values for the SARCOS-Brazil criteria were obtained from the 25th percentile of each variable. Results and Discussion: There was no difference in the prevalence of muscle weakness using the two methods (180 patients, 35.9% of the sample). However, a difference was observed concerning low muscle mass. According to the European criteria, a total of 215 older individuals (42.8%) had low muscle mass and 123 (24.5%) according to the SARCOS-Brazil criteria. The prevalence of sarcopenia was 20.3% according to European criteria versus 13.7% according to the SARCOS-Brazil criteria. The kappa coefficient was 0.79. Conclusion: This study suggests that weakness and muscle mass can, in isolation, predict variables related to past vulnerability outcomes, as well as highlights the possibility of using regional cutoff values for the diagnosis of sarcopenia.

Background:Subjective Memory Complaints (SMC) are common in clinical practice. the clinical significance of these subjective complaints among older individuals is not well understood.Aim:To study and discuss the association between SMC and MCI, underlining the importance of an adequate clinical assessment of SMC in the elderly.Methods:Review of the literature.Results:There is no consistent definition of SMC in the literature. Some prospective studies showed an association with objective memory impairments, conceptualizing SMC as a Pre-Mild Cognitive Impairment. SMC are also currently considered to be a core feature of Mild Cognitive Impairment (MCI). Cross-sectional studies and longitudinal studies showed conflicting results concerning the association between SMC and MCI.Discussion:The understanding of the predictive value of SMC in cognitive decline is still poorly understood. It is important to define criteria aimed to increase specificity of memory complaints, allowing an earlier identification of populations with higher risk of MCI. Future research on this complex association is important to identify SMC individuals at increased risk of conversion to MCI and dementia.

AbstractThe possible roles of selected B vitamins in the development and progression of sarcopenia are reviewed. Age-related declines in muscle mass and function are associated with huge and increasing costs to healthcare providers. Falls and loss of mobility and independence due to declining muscle mass/function are associated with poor clinical outcomes and their prevention and management are attractive research targets. Nutritional status appears a key modifiable and affordable intervention. There is emerging evidence of sarcopenia being the result not only of diminished anabolic activity but also of declining neurological integrity in older age, which is emerging as an important aspect of the development of age-related decline in muscle mass/function. In this connection, several B vitamins can be viewed as not only cofactors in muscle synthetic processes, but also as neurotrophic agents with involvements in both bioenergetic and trophic pathways. The B vitamins thus selected are examined with respect to their relevance to multiple aspects of neuromuscular function and evidence is considered that requirements, intakes or absorption may be altered in the elderly. In addition, the evidence base for recommended intakes (UK recommended daily allowance) is examined with particular reference to original datasets and their relevance to older individuals. It is possible that inconsistencies in the literature with respect to the nutritional management of sarcopenia may, in part at least, be the result of compromised micronutrient status in some study participants. It is suggested that in order, for example, for intervention with amino acids to be successful, underlying micronutrient deficiencies must first be addressed/eliminated.

Dietary protein has a pivotal role in muscle mass maintenance with advancing age. However, an optimal dose and distribution of protein intake across the day as well as the interaction with energy intake for the maintenance of muscle mass and physical function in healthy older adults remain to be fully elucidated. The purpose of this study was to examine the association between muscle mass, strength, and physical function, and the total amount and distribution of protein and energy intake across the day in healthy older individuals. The research question was addressed in a cross-sectional study including 184 Danish men and woman (age: 70.2 ± 3.9 years, body mass: 74.9 ± 12.1 kg, Body Mass Index (BMI): 25.4 ± 3.7 kg/m2) where a 3-day dietary registration, muscle mass, strength, and functional measurements were collected. We found that neither daily total protein intake nor distribution throughout the day were associated with muscle mass, strength, or physical function. Consequently, we do not provide an incentive for healthy older Danish individuals who already adhere to the current internationally accepted recommended dietary protein intake (0.83 g/kg/day) to change dietary protein intake or its distribution pattern throughout the day.

Muscle loss with age has a negative effect on strength and functional independence. Age-related loss of muscle is the result of decreased muscle fiber number and size, which are functions of altered hormonal status, physical inactivity, and variations in nutritional intake. Resistance training has a positive effect on muscle mass and strength in the elderly. Studies of protein or creatine supplementation for increasing muscle mass and strength in older individuals are equivocal. The timing of nutritional supplementation may be more important than the absolute daily intake of supplements. Protein or creatine ingestion proximate to resistance-training sessions may be more beneficial for increasing muscle mass and strength than ingestion of protein or creatine at other times of the day, possibly because of increased blood flow and therefore increased transport of amino acids and creatine to skeletal muscle.
