In this one, interrupting periods of what otherwise would be prolonged sitting every 30 minutes for 3 minutes of resistance training led to reductions in postprandial glucose and insulin response by 32% and 26%, respectively.
- In this randomized crossover study, 30 participants with a mean age of 25.4 years completed two intervention arms, beginning at ~1700 h: prolonged sitting for 4 h; and sitting with regular activity breaks of 3 min of resistance exercises every 30 min.
- Interrupting periods of prolonged sitting by regularly performing resistance exercise breaks in the evening reduces postprandial glucose and insulin response in the overall study population by 32% and 26% respectively.
- Clinically meaningful reductions in postprandial glucose and insulin responses were observed across all BMI categories...
"...indicating that healthy adults across the BMI spectrum could benefit from interrupting prolonged sitting in the evening with regular short bouts of resistance exercises."
- However, the magnitude of the effect did appear to differ by BMI category.
Breaking Up Evening Sitting with Resistance Activity Improves Postprandial Glycemic Response: A Randomized Crossover Study
This one not only brings forth evidence that challenges the current crossover concept, it also suggests that low-carb diets may also reverse features of pre-diabetes and future metabolic disease risk.
- The article (mostly) used data from these two papers:
- The data from these studies sheds doubt to the popular concept that human athletes are unable to extract any meaningful degree of energy from fat oxidation during exercise at intensities >85%VO2max.
In this one, high intakes of seafood, and particularly small fish rich in n-3 fatty acids, was associated with a lower risk of 10-year fatal and non-fatal cardiovascular disease risk in Greek adults with a mean age of 45.2 years.
- Less than one-10th of the study participants consumed >1 serving of small fish rich in n-3 fatty acids per week.
- Participants who consumed >2 servings per week of seafood had at least 27% decreased risk of developing CVD and 74% lower 10-year risk of dying due to CVD.
Interestingly, using NMR spectroscopy, this one suggests that newly manifest type 2 diabetes-associated dyslipoproteinemia does not significantly change the total concentrations of the lipoproteins produced in the liver, but selectively their subclass distributions.
- In the present study, German long time blood donors that were assumed to be healthy according to the rules applying for blood donors were examined.
Impaired fasting glucose, impaired glucose tolerance or manifest type 2 diabetes were not known for this group before they were included in this study.
In this one, 3 isocaloric meals with different macronutrient compositions showed different postprandial metabolic profiles, with postprandial exercise altered substrate oxidation and preventing hyperglycemia induced by an high-carbohydrate meal.
- The study aimed to assess the collective effects of 3 isocaloric meals: higher in carbohydrate (74.2% energy), fat (64.6% energy), or protein (39.5% energy) on energy expenditure and clinical and metabolomic biomarkers in men with normal weight or overweight/obesity.
- The 3 isocaloric diets varying in macronutrients showed distinctive postprandial metabolic profiles, while exercise altered substrate oxidation and inhibited the hyperglycemia induced by the higher-carbohydrate meal.
This systematic overview suggests that the literature overall confirms the existence of the physical activity paradox in healthcare workers.
- The physical activity paradox states that even though leisure-time (particularly moderate-to-vigorous) physical activity promotes health, more relative time spent on (particularly moderate-to-vigorous) physical activity during work seems to impair health.
- This systematic overview found that, in healthcare workers, occupational physical activity is primarily conducted at light to moderate-intensity and leisure-time physical activity at light- to high intensity.
This one found no differences in the postprandial rise in muscle protein synthesis rates following ingestion of 30g protein provided either as cheese or as milk protein at rest or during recovery from exercise in healthy, young males.
- The study compared the impact of ingesting 30g protein provided in the form of cheese or milk protein concentrate on postprandial muscle protein synthesis rates in vivo in 20 healthy, young males.
- An increase in circulating amino acid concentrations following the ingestion of 30g protein provided either as cheese or milk protein was observed.
