Vegan and Omnivorous High Protein Diets Support Comparable Daily Myofibrillar Protein Synthesis Rates and Skeletal Muscle Hypertrophy in Young Adults

AbstractBackgroundIt remains unclear whether non–animal-derived dietary protein sources (and therefore vegan diets) can support resistance training-induced skeletal muscle remodeling to the same extent as animal-derived protein sources.MethodsIn Phase 1, 16 healthy young adults (m = 8, f = 8; age: 23 ± 1 y; BMI: 23 ± 1 kg/m2) completed a 3-d dietary intervention (high… Continue reading Vegan and Omnivorous High Protein Diets Support Comparable Daily Myofibrillar Protein Synthesis Rates and Skeletal Muscle Hypertrophy in Young Adults

Morning Exercise Reduces Abdominal Fat and Blood Pressure in Women; Evening Exercise Increases Muscular Performance in Women and Lowers Blood Pressure in Men

The ideal exercise time of day (ETOD) remains elusive regarding simultaneous effects on health and performance outcomes, especially in women.Purpose: Given known sex differences in response to exercise training, this study quantified health and performance outcomes in separate cohorts of women and men adhering to different ETOD.Methods: Thirty exercise-trained women (BMI = 24 ± 3… Continue reading Morning Exercise Reduces Abdominal Fat and Blood Pressure in Women; Evening Exercise Increases Muscular Performance in Women and Lowers Blood Pressure in Men

Higher protein intake during caloric restriction improves diet quality and attenuates loss of lean body mass

ObjectiveHigher protein intake during weight loss is associated with better health outcomes, but whether this is because of improved diet quality is not known. The purpose of this study was to examine how the change in self-selected protein intake during caloric restriction (CR) alters diet quality and lean body mass (LBM). MethodsIn this analysis of… Continue reading Higher protein intake during caloric restriction improves diet quality and attenuates loss of lean body mass

#Dysbiosis of the gut microbiome impairs mouse skeletal #muscle adaptation to exercise

Dysbiosis of the gut microbiome caused by continuous antibiotic treatment did not affect running activity.Continuous treatment with antibiotics did not result in systemic inflammation as indicated by serum cytokine levels.Gut microbiome dysbiosis was associated with blunted fiber-type specific hypertrophy in the soleus and plantaris muscles in response to progressive weighted wheel running (PoWeR).Gut microbiome dysbiosis… Continue reading #Dysbiosis of the gut microbiome impairs mouse skeletal #muscle adaptation to exercise

Distribution of dietary #protein intake in daily meals influences skeletal #muscle hypertrophy via the muscle clock

Distribution of dietary protein across meals influences muscle hypertrophy•BCAAs are involved in hypertrophic effects of protein feeding distribution•Hypertrophic effects of protein feeding distribution require the muscle clock•Breakfast protein intake is correlated with skeletal muscle functions in older women SummaryThe meal distribution of proteins throughout the day is usually skewed. However, its physiological implications and the… Continue reading Distribution of dietary #protein intake in daily meals influences skeletal #muscle hypertrophy via the muscle clock

VPS39-deficiency observed in type 2 #diabetes impairs #muscle stem cell differentiation via altered autophagy and epigenetics

Insulin resistance and lower muscle quality (strength divided by mass) are hallmarks of type 2 diabetes (T2D). Here, we explore whether alterations in muscle stem cells (myoblasts) from individuals with T2D contribute to these phenotypes. We identify VPS39 as an important regulator of myoblast differentiation and muscle glucose uptake, and VPS39 is downregulated in myoblasts… Continue reading VPS39-deficiency observed in type 2 #diabetes impairs #muscle stem cell differentiation via altered autophagy and epigenetics

Skeletal muscle antagonizes antiviral CD8+ T cell exhaustion

CD8+ T cells become functionally impaired or “exhausted” in chronic infections, accompanied by unwanted body weight reduction and muscle mass loss. Whether muscle regulates T cell exhaustion remains incompletely understood. We report that mouse skeletal muscle increased interleukin (IL)–15 production during LCMV clone 13 chronic infection. Muscle-specific ablation of Il15 enhanced the CD8+ T cell… Continue reading Skeletal muscle antagonizes antiviral CD8+ T cell exhaustion

#Potato Protein Isolate Stimulates #Muscle Protein Synthesis at Rest and with Resistance Exercise in Young Women

Skeletal muscle myofibrillar protein synthesis (MPS) increases in response to protein feeding and to resistance exercise (RE), where each stimuli acts synergistically when combined. The efficacy of plant proteins such as potato protein (PP) isolate to stimulate MPS is unknown. We aimed to determine the effects of PP ingestion on daily MPS with and without… Continue reading #Potato Protein Isolate Stimulates #Muscle Protein Synthesis at Rest and with Resistance Exercise in Young Women

Skeletal #muscle mass in relation to 10 year #cardiovascular disease incidence among middle aged and older adults: the ATTICA study

Skeletal muscle mass (SMM) is inversely associated with cardiometabolic health and the ageing process. The aim of the present work was to evaluate the relation between SMM and 10 year cardiovascular disease (CVD) incidence, among CVD-free adults 45+ years old. The 10 year CVD incidence increased significantly across the baseline SMI tertiles (p<0.001). Baseline SMM showed a significant… Continue reading Skeletal #muscle mass in relation to 10 year #cardiovascular disease incidence among middle aged and older adults: the ATTICA study
