“…Despite the divergent energy availability between groups (Table 1), there were no differences in RMR, sleep or hunger, and substrate utilization, and perceptual responses were comparable between trials. There was, additionally, a large use of fat of ∼1.1 g min −1 exercising at 60% of

{\dot{V}}_{O_{2} \max}

(Table 3) in both groups, which is close to twofold that of the maximal rate of fat oxidation we observed in athletes under normal conditions (Areta, Austarheim, Wangensteen, & Capelli, 2018). Data therefore are in agreement with classic literature (Bergström et al., 1967) which shows that local glycogen and carbohydrate availability are key factors in regulating substrate metabolism, which was the key common factor in both of our groups.…”

Training with low carbohydrate availability (LCHO) has been shown to acutely enhance endurance training skeletal muscle response, but the concomitant energy deficit (ED) in LCHO interventions has represented a confounding factor in past research. This study aimed at determining if achieving energy balance with high fat (EB-HF) acutely enhances the adaptive response in LCHO compared to ED with low fat (ED-LF). In a crossover design, nine well-trained males completed a 'sleep-low' protocol: on day 1 they cycled to deplete muscle glycogen while reaching a set energy expenditure (30 kcal (kg of fat free mass (FFM)) −1). Post-exercise, low carbohydrate, proteinmatched meals completely (EB-HF, 30 kcal (kg FFM) −1) or partially (ED-LF, 9 kcal (kg FFM) −1) replaced the energy expended, with the majority of energy derived from fat in EB-HF. In the morning of day 2, participants exercised fasted, and skeletal muscle and blood samples were collected and a carbohydrate-protein drink was ingested at 0.5 h recovery. Muscle glycogen showed no treatment effect (P < 0.001) and decreased from 350 ± 98 to 192 ± 94 mmol (kg dry mass) −1 between rest and 0.5 h recovery. Phosphorylation status of the mechanistic target of rapamycin and AMP-activated protein kinase pathway proteins showed only time effects. mRNA expression of p53 increased after exercise (P = 0.005) and was higher in ED-LF at 3.5 h compared to EB-HF (P = 0.027). Plasma glucose and insulin area under the curve (P < 0.04) and peak values (P ≤ 0.05) were higher in EB-HF after the recovery drink. Achieving energy balance with a high-fat meal in a 'train-low' ('sleep-low') model did not enhance markers of skeletal muscle adaptation and impaired glycaemia in response to a recovery drink following training in the morning.

“…Mate tea was a good antioxidant due to its high amount of chlorogenic acid and was at the forefront with this feature 15 . However, it showed auxiliary effects on slimming with the high absorption of caffeine in its content, accompanied by sports and a low diet 18 . It has shown successful results depending on the dose in clinical studies with caffeine, epigallocatechin, and a high amount of polyphenol in green tea content.…”

“…Caffeine prevented thermogenesis from induction of cyclic adenosine monophosphate (cAMP) from phosphodiesterase and ensured fat burning not to stop 17 . Mate tea compounds provided high fat burning in individuals who did not exercise, but their effects have not been examined in sedentary individuals 18 . In a study conducted with the preparation of Mate tea on obese people, while the group receiving the placebo remained at the same weight, the gastric emptying period of the obese group taking the preparation was prolonged, and a significant decrease in weight was observed with the support created by the feeling of satiety at the end of the 45 days 19 .…”

“…With catechol-O-methyltransferase (COMT) inhibition of chlorogenic acid and caffeoyl derivatives, increased adrenaline has been observed. With the interaction of chlorogenic acids and caffeine in the content of Mate tea, it created an ergogenic effect in the study 18 . During eight weeks, the consumption of mate tea caused a decrease in glucose, cholesterol, TG, HDL, LDL values of the experimental animal group fed on a high-fat diet.…”

The replacement of consumed with foods containing high carbohydrates, fats and proteins exceed that the daily needs of body, causes many health problems, especially obesity. Complicated health problems have been trying to be solved with drugs, but it is not possible to control diseases if obesity is not resolved. Obesity causes inflammation, insulin resistance, vascular endothelial dysfunction, and Low-Density Lipoprotein (LDL) increase. There are very few weight loss drugs with acceptable side effects, and these drugs are not given to people who are not considered obese according to their body mass index. For this reason, people seek the remedy in over the counter (OTC) (mostly products with active ingredients derived from plants) products or herbal teas. These products, which do not have direct effects, have mechanisms that can help and can be supportive with diet and sports. However, these products and teas that cannot be dosed by a knowledgeable healthcare professional can disrupt the balance of the body and cause various diseases. In this study, the effect levels with the mechanisms supporting weight loss on the biochemical parameters of the active substances in the herbal forms sold and consumed as diet tea, were evaluated.

The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

Exercise-induced aerobic bioenergetic reactions in mitochondria and cytosol increase production of reactive oxygen species. Many efforts have been carried out to identify dietary strategies or micronutrients able to prevent or at least attenuate the exercise-induced muscle damage and stress. A lot of studies are about how effective dietary intervention and oral antioxidant supplementation may be in reducing oxidative stress in athletes who exercise intensively. Commonly used nonenzymatic supplements have been proposed as ways to prevent exerciseinduced oxidative stress and hence improve adaptation responses to endurance training. Plant-derived bioactive compounds can repress inflammation by inhibiting oxidative damage and interacting with the immune system. This review focuses on polyphenols and phytochemicals present in the plant kingdom that have been recently suggested to exert some positive effects on exercise-induced muscle damage and oxidative stress. This review will summarize some of the actual knowledge on polyphenolic compounds that have been demonstrated both to exert a significant effect in exercise-induced muscle damage and to play a biological/physiological role in improving physical performance. Overall, the pooled results show that polyphenols are viable supplements to improve performance in athletes.
