Summary: This study compares the kinetic and kinematic differences between accentuated eccentric loading (AEL), traditional loading, and cluster sets in the bench press. The findings suggest that inter-repetition rest has an influence on concentric performance, particularly mean power and mean velocity, and may be beneficial when using higher loads and sustained power outputs. Additionally, accentuated eccentric loading may alter loading parameters compared to traditional loading conditions.

Summary: This study aimed to investigate the role of oral microbiota profiles and oral nitrate-reducing capacity in explaining individual differences in blood pressure (BP) lowering following dietary nitrate supplementation. The results showed that women with hypertension had lower salivary nitrite concentrations and reduced abundance of nitrate-reducing bacteria compared to normotensive women. Oral nitrate reductase (NaR) activity did not differ significantly between pregnant and nonpregnant women, but it tended to be lower in hypertensive women. Oral NaR activity was associated with both baseline diastolic BP and changes in diastolic BP after acute nitrate intake.

Summary: This systematic review and meta-analysis examined the impact of dietary nitrate supplementation on resistance exercise performance. Six studies were analyzed and showed that nitrate supplementation improved repetitions-to-failure, mean power, and mean velocity but had no effect on peak power or peak velocity. Subgroup analyses suggested that back squats were more likely to be enhanced and dosing regimens may influence the efficacy of nitrate supplementation. Additional studies are needed to further understand the effects of dietary nitrate supplementation on resistance exercise performance.

Summary: The study found that using arch technique increases latissimus dorsi activation while decreasing shoulder loading, helping to minimize time spent in the sticking region where most lift efforts fail. These technique-specific differences can be utilized in performance or rehabilitation programs to increase muscular output of some muscles without increasing overall loading.

Summary: This study aimed to evaluate the effects of a dietary supplement (Diuripres®) containing magnesium, orthosiphon extract, hawthorn, and hibiscus on blood pressure, vascular health, and metabolic parameters in individuals with high-normal blood pressure or stage I hypertension. The results showed that supplementation with Diuripres® significantly reduced systolic and diastolic blood pressure, as well as improved cardiovascular health indicators.

Summary: The study found that magnesium (Mg) supplementation has limited effects on body weight and obesity measures in patients with type 2 diabetes mellitus (T2DM), but can significantly reduce systolic and diastolic blood pressure in these patients. Subgroup analysis suggested that Mg supplementation for more than 12 weeks, at doses higher than 300 mg/day or inorganic forms, could be particularly effective in reducing blood pressure in T2DM patients. Further research is needed to provide more reliable evidence on the benefits of Mg supplementation for this patient population.

Summary: In patients with CKD, higher serum magnesium levels are associated with lower systolic and diastolic blood pressure, as well as a reduced risk of hypertension and CKD progression. Further research is needed to investigate whether magnesium supplementation could optimize blood pressure control and prevent disease progression in this population.

Summary: This study found a significant positive association between magnesium and systolic blood pressure among patients with hypertensive crises. This positive association of serum magnesium with systolic blood pressure was maintained after adjusting for covariates, suggesting a potential role of magnesium in blood pressure among patients with hypertensive crises.

Summary: This study examined the acute effects of lower-body high-intensity interval loading (HIIT) on explosive upper- and lower-body strength, as well as the combined effect of HIIT and bench-press loading versus HIIT and squat loading on the explosive upper- and lower-body strength. The findings indicate that lower-body explosive strength is acutely reduced by preceding lower-body HIIT, and both squat and bench-press explosive strength are similarly reduced when combined with lower- or upper-body strength loading.

Summary: In this study, a randomized trial was conducted on overweight and slightly obese individuals, and it was found that oral magnesium supplements had no significant effects on arterial stiffness and blood pressure. The effects of magnesium citrate, magnesium oxide, and magnesium sulfate were also not significantly different.

Summary: This study found that combined magnesium and vitamin D treatment may be more effective in increasing serum 25OHD concentrations compared to vitamin D supplementation alone in overweight and obese individuals, and it also has the potential to lower baseline systolic blood pressure.

Summary: Astaxanthin supplementation leads to a slight decrease in diastolic blood pressure in adults, especially in patients and participants from Asian countries. This effect is more pronounced with a dosage of > 12 mg/day supplementation.

Summary: This study analyzed the results of 24 randomized controlled trials and found that individuals with type 2 diabetes who received magnesium supplementation had significant reductions in fasting plasma glucose, glycated hemoglobin, systolic blood pressure, and diastolic blood pressure. The effects of magnesium supplementation were influenced by factors such as age, body mass index, disease duration, magnesium level, glycemic control condition, magnesium formulation, dosage, and duration of intervention.

Summary: This study analysed the effect of creatine supplementation on performance improvement in a bench pressing strength test and evaluated muscle fatigue and metabolic stress during a 20-minute recovery period. The results showed that the creatine group had more repetitions after supplementation, but experienced greater metabolic stress and muscle fatigue during the recovery period.

Summary: This study revealed the crucial role of vascular endothelial NPR1 in ANP-mediated blood pressure regulation. ANP lowers blood pressure by activating potassium channels and modulating G-protein signaling pathways in endothelial cells. Furthermore, ANP's blood pressure regulation depends on RGS2 in the acute phase but is independent of RGS2 in the chronic phase.
