This study sheds doubt on the impact of the food matrix on anabolism, as it found that eating salmon as a whole-food matrix is similarly anabolic compared to ingesting the same nutrients as an isolated mixture of crystalline amino acids and fish oil following resistance exercise.
- The study tried to assess the effects of eating salmon versus ingesting the same nutrients as an isolated mixture of crystalline amino acids and fish oil on the stimulation of post-exercise myofibrillar protein synthesis and whole-body leucine oxidation rates.
- Ten recreationally active adults performed an acute bout of resistance exercise followed by the ingestion of salmon or the isolated mixture in a crossover fashion.
- The ingestion of salmon resulted in a more prolonged postprandial increase in plasma leucine concentrations...
...which led to a delayed stimulation of whole-body leucine oxidation rates when compared to the ingestion of isolated nutrients during the immediate recovery period after resistance exercise.
- The ingestion of salmon also resulted in lower postprandial insulin concentrations, and larger plasma EPA concentrations.
- However, both the temporal (0-2 or 2-5 h) and cumulative (0-5 h) stimulation of post-exercise myofibrillar protein synthesis rates were not statistically significantly different between the two conditions.
Underpinning the food matrix regulation of post-exercise myofibrillar protein synthesis by comparing salmon ingestion versus the sum of its isolated nutrients in healthy young adults
The findings of this one suggest that the risk of major depressive disorder may be lowered, even among individuals with a high genetic risk, by a higher strength, as measured by grip strength.
- Individuals with low genetic risk and high grip strength had a lower incidence of major depressive disorder compared with individuals with high genetic risk and low grip strength.
- Individuals with high genetic risk and high grip strength also had a lower incidence of major depressive disorder compared with individuals with high genetic risk and low grip strength.
This is the last part of the series of systematic reviews and meta-analyses that this group performs in an effort to synthesize the evidence that links physical activity with breast cancer risk.
This systematic review finds that the literature overall suggests that passive or active normobaric intermittent hypoxia probably has a limited positive effect on health-related outcomes in healthy older adults compared to similar intervention in normoxia.
Key points:
- Passive and active intermittent normobaric hypoxia is likely to have a limited effect on health-related outcomes in healthy older adults, compared to a similar intervention in normoxia.
Here, the combination of exercise and a GLP-1 receptor agonist reduced metabolic syndrome severity, abdominal obesity, and inflammation following an eight-week low-calorie diet, consequently reducing cardiometabolic risk more than exercise or the GLP-1 receptor agonist alone.
- The study investigated improvements in metabolic syndrome, abdominal obesity, and low-grade inflammation during moderate-to-vigorous exercise, liraglutide 3.0 mg/day, or the combination of the two following an eight-week low-calorie diet...
...in a one-year maintenance period following a diet-induced weight loss.
This systematic review and meta-analysis suggests that cold water immersion is likely to benefit the acute recovery of endurance performance and longer-term recovery of muscle strength and power, although this may depend on the nature of the preceding exercise.
- Findings supported that cold water immersion is likely to best facilitate the recovery of endurance performance when the preceding exercise is endurance in nature and particularly when the preceding exercise is performed in the heat:
Findings suggested that that post-exercise cold water immersion is likely to enhance the acute recovery (i.e., 1 h) of endurance performance following exercise in warm-to-hot (26°C to 40°C) conditions...
How accurate is the Oura Ring in estimating energy expenditure?
It can identify major changes between activities and/or intensities but is less responsive to detailed deviations within activities, this study suggests.
- This study aimed to determine the validity of Oura Ring step-count and energy expenditure against indirect calorimetry in the laboratory and a free-living setting against accelerometers and a pedometer.
- Results from the laboratory indicated that the Oura can successfully identify major changes between various activities and/or intensities with acceptable measurement error overall, but is less responsive to detailed deviations within different activities and/or intensities.
