Green tea consumption is known to have metabolic effects but is also consumed for supposed calming effects. The aim of the present study was to examine the effects of encapsulated Matcha green tea on heart rate variability metrics during supine rest, as well as on physiological and metabolic responses during both supine rest and moderate-intensity exercise. Methods: Healthy females (n=8, age: 22±3 yrs, body mass: 68±11 kg, height: 162±5 cm) volunteered. The study employed a placebo-controlled, randomised cross-over design. Time-domain heart rate variability metrics during supine rest (n=5) and physiological and metabolic responses using indirect calorimetry techniques during supine rest and 60-min of moderate-intensity (~ 4-METs) treadmill walking (speed: 4.4±0.5 km·h-1) were measured following 3 weeks of 3 g·day-1 of Matcha green tea or placebo. Results: During supine rest with Matcha green tea, all participants had lower heart rates by 13±7% (P=0.01, d= -1.45), higher mean beat-to-beat RR intervals by 16±9% (P=0.03, d=1.25), higher SDNN by 44±32% (P=0.01, d=0.76) and higher pNN50 by 139±139% (P<0.01, d=1.28). Matcha green tea had no effects on the physiological and metabolic responses during supine rest and moderate-intensity treadmill walking (e.g. respiratory exchange ratio, placebo: 0.78±0.04; Matcha: 0.78±0.03, P=0.87). Fat oxidation during supine rest was correlated (r=0.75, P<0.01) with the moderate-intensity walking induced fat oxidation. Conclusions: In young adult healthy females, Matcha green tea beneficially effects heart rate variability metrics during supine rest indicating an alteration in parasympathetic nervous activity and therefore suggestive of a relaxing effect. Matcha green tea did not change the metabolic responses during supine rest and exercise possibly due to the low respiratory exchange ratio in the female cohort. Future work should address the effectiveness of Matcha green tea during conditions of psychological stress.Keywords: Matcha green tea, heart rate variability, rest, walking, substrate oxidation ","PeriodicalId":320142,"journal":{"name":"Dietary Supplements and Nutraceuticals","volume":"54 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139603452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined for supine rest the effects of a 2-week daily intake of NZBC extract on physiological and metabolic parameters in relation to body fat%.Methods: Healthy active men (n=16, age: 24.1±6.0 yr, body mass: 78.2±15.6 kg, BMI: 24.7±4.2 kg·m-2) volunteered. NZBC extract (210 mg of anthocyanins) was consumed with breakfast with a14-day washout. The final ingestion was 2 hours before testing. Physiological and metabolic responses were measured during supine rest (2x10 min), and observations with the lowest 10-minute ventilation were analyzed. Bioelectrical impedance analysis was used to measure body fat%.Results: During supine rest, a 14-day daily intake of NZBC extract had no effect on heart rate, minute ventilation, oxygen uptake, carbon dioxide production, and energy expenditure. However, a 14-day daily intake of NZBC extract decreased the respiratory exchange ratio (baseline: 0.840±0.045, 14-day: 0.820±0.058, P=0.03), increased fat oxidation (baseline: 0.079±0.03, 14-day: 0.088±0.043 g·min-1, P=0.05), and decreased carbohydrate oxidation (baseline: 0.178±0.067, 14-day: 0.143±0.071 g·min-1, P=0.03) during supine rest. Nine of the 16 participants had increased fat oxidation by over 10% during supine rest. For those nine participants, the increases were 26±16%. We did not observe a significant correlation between body fat% and absolute and percentual changes in fat oxidation.Conclusions: In a healthy male cohort, daily intake of New Zealand blackcurrant extract for two weeks was able to increase fat oxidation during supine rest.

The physical and chemical properties of edible films made with zinc oxide ZnONPs and active phenol compounds extracted from pomegranate peel (PPE) were studied. Adding ZnONPs with active phenol compounds from extracted pomegranate peel (PPE) to chitosan films can provide safe edible films, decrease microbial growth, consequently, prolong the shelf life of pomegranates, and improve the physiochemical stability of the pomegranate.

Squalene as a bioactive compound has been shown to have several health benefits specifically in the reduction of diabetic symptoms, including anti-inflammatory effects.Objective: The purpose of the study was to examine effect of squalene on specific parameters regarding energy production and inflammation in those with type 2 diabetes mellitus. These parameters included ATP, NAD/NADH, CoQ10, NFκB, IκB-alpha, IκK-alpha, and IκK-beta.Methods: 150 volunteers were selected for this study split into 5 groups. Group 1 contained 30 healthy participants and served as the control. The remaining 120 participants were split into 4 groups containing 30 volunteers each.
