Here, one year of protein supplementation in comparison to an isocaloric-control supplement appeared to affect neither the muscle protein synthesis rate at basal or postprandial state nor the skeletal muscle metabolomein healthy older Danes.
- The skeletal muscle mass decreases with age and the responsiveness of aging muscles protein synthesis rate to protein intake seems to deteriorate.
- This study investigated the impact of 12 months of protein supplementation with or without physical exercise training on the basal and postprandial muscle protein synthesis and the skeletal muscle metabolome of healthy older Danes (> 65 years, 29 females/37 males).
- Subjects were randomized to follow one of five intervention groups:
* Carbohydrate
* Collagen protein
* Whey protein
* Home-based light resistance training with whey protein
* Center-based heavy-load resistance training with whey protein.
- One year of daily protein or carbohydrate supplementation neither seemed to alter the basal nor the protein-stimulated postprandial muscle protein synthesis rate in healthy older adults.
- In contrast to previous findings, no differences in basal protein synthesis rates between males and females were observed.
Effect of 1-year daily protein supplementation and physical exercise on muscle protein synthesis rate and muscle metabolome in healthy older Danes: a randomized controlled trial (open access)
The findings of this one suggest that dietary carbohydrate and exercise may generate independent and interactive effects on the plasma metabolome, resulting in the generation of distinct metabolic phenotypes that may influence appetite regulation and perhaps energy intake.
- This study aimed to determine the interactive effects of carbohydrate and exercise on the plasma hormonal and metabolite responses and explore potential mediators of exercise-induced changes in appetite and energy intake across nutritional states.
- In a randomised-crossover fashion, 12 male participants completed four study visits that involved the consumption of a control (water) or carbohydrate beverage (75 g maltodextrin, 300 kcal), followed by a 30-minute rest or exercise session (75% V'O2max on a cycle ergometer).
In this one, low upper and lower limb strength were associated with higher all-cause mortality risk in Chinese older adults with a mean age of 84.98 years.
- This study aimed to examine the association of upper limb strength and lower limb strength with all cause mortality based on the Chinese Longitudinal Healthy Longevity Survey.
- Participants were 2442 older adults (aged 84.98 ± 11.94 years) recruited from eight longevity areas in China.
The aim of this paper was to overview methods and results of studies that compared acute changes in muscle strength after bouts of maximal eccentric and concentric resistance exercise.
- "Perhaps the main implication of the current work is that ECC resistance exercise prescriptions should account for the muscle group being exercised...
"...The elbow flexors are more susceptible to acute strength loss and damage from ECC exercise than are muscles of the lower limbs...
In this one, a multimodal exercise training intervention was found to be an effective strategy in improving muscular strength, agility, dynamic balance and depressive symptoms in men with mild-to-moderate Alzheimer's disease.
- The aim of this study was to investigate the effect of multimodal exercise training on aerobic endurance, muscular strength, agility, dynamic balance, cognitive status, and depressive symptoms in men with mild-to-moderate Alzheimer's disease.
- A total of 25 elderly men with a diagnosis of mild-to-moderate Alzheimer's disease were randomly categorized into a a multimodal exercise training program or a control group.
The findings of this one in mice suggest that adolescent exposure to THC may promote an enduring “pseudo-lean” state that superficially resembles healthy leanness but might in fact be rooted in adipose organ dysfunction.
- A THC administration regimen that approximates daily human use of a low psychoactive dose of the drug dampened body weight gain in adolescent mice.
- When treatment was stopped, THC-treated mice expended more energy than did vehicle-treated controls and, by the time they reached adulthood, transitioned to a different metabolic state.
In this one, even though the consumption of 42.5g mixed nuts per day for 16 weeks was associated with some favorable cardiometabolic risk factor changes, it was not associated with statistically significant changes on LDL-c or Lp(a) in individuals with overweight and obesity.
- The aim of this randomized controlled trial was to examine the effects of mixed nut supplementation on Lp(a), lipid profiles, and inflammation in individuals with overweight and obesity.
- Participants randomly assigned to the intervention group were provided with 42.5 g/day packets of mixed nuts consisting of 25.5 g of nut mixture (cashews, almonds, macadamia nuts, Brazil nuts, pecans), 5 g of pistachios, 5 g of walnuts, and 7 g of peanuts.
