The use of local daily food as supplements over expensive drinks is cost–effective for athletes. Hence, SA (carbohydrate) could be recommended as affordable nutrition ingestion. The purpose of this study was to determine the effects of SA, Soy (SO) protein, Sago+Soy (SS) supplementation (combination of carbohydrate and protein), and placebo (PL) during moderate–intensity cycling on subsequent 20–km time trial performance. Materials and Methods: The participants were 12 young male well–trained cyclists from Malaysia. They pedaled at 60% of VO2max for 90 min followed by a 20–km time trial (TT) in the heat. At 20 min intervals during cycling at 60% VO2max, participants consumed either SA, SO, SS, or a PL. The SA, SO, and SS feedings provided 7.5% SA, 7.5% SO, and 7.5% SA+1.5% SO respectively to drink iso–caloric beverages with an estimated energy level ~300 kcal. The average speed and cadence were also recorded during the TT. Results: Time taken for TT for SA, SO, SS, and PL were 42.8±1.8 min, 46.3±2.6 min, 42.7±2.3 min, and 43.2±1.8 min respectively. The TT performance, speed, and cadence of the cyclists did not exhibit any significant differences among the three trials. Conclusion: These data indicated that consumption of sago and soy, and iso–caloric SS (coingestion of sago and soy) during steady–state ride failed to improve the subsequent cycling performance in the heat.

It is recommended that a nutritionist maintain a long-term relationship with each athletics institute. This gap in nutrition knowledge and modifiable nutrition behaviors can be closed by establishing a nutrition teaching and evaluation tool for coaches and young athletes. An overview of soccer nutrition covers the nature of the sport, training, and how nutrition may enhance player performance and recovery. Soccer competitions require players to engage in acyclical and intermittent activity patterns spanning up to 13 kilometers. The limited muscle glycogen reserves are a crucial component of the interface between training, performance, and nutritional support. Diets rich in carbohydrates may optimize muscle glycogen, minimize net glycogen depletion, postpone tiredness onset, and improve soccer performance. However, it is more frequent for the players to take an excessive quantity of protein daily, promoting the myth that extra protein improves strength and performance. More extensive suggestions include that soccer players should take a high CHO diet consisting of nutrient-dense, complex CHO food sources. Thus, despite the precise physiological demands of soccer and the relationship between nutritional preparation and performance, soccer players' dietary habits are frequently marked by a need for more education and misguided traditions. As soccer players and coaches in Iran become more aware of the importance of sustaining optimal macronutrient nutrition, this article discusses potential barriers and various nutrition phases to consider during training, on the day of the competition, and after the competition.

Therefore, the purpose of this research is to investigate the effect of eight weeks of aerobic training and papaya supplement consumption on the lipid profile of men with fatty liver. Materials and Methods: The statistical population of the present study included all men with fatty liver in Yazd city, among whom there were 60 men with an average age of 25 to 35 years and a body mass index between 25 and 35 kg/m2, were randomly divided into four groups of 15 including aerobic exercise group, aerobic exercise group-papaya supplement, papaya supplement group and control group. The subjects of the training and training-supplementary group performed aerobic exercise according to the given program for eight weeks, three sessions per week and each session lasted for 70 minutes. In the same period, the supplement and training groups also received a papaya supplement in the form of capsules at a dose of 30 mg per kilogram of body weight every day after dinner. Karika Papaya Slim capsules produced in the Philippines in 2021 were prepared. Blood samples were taken from the subjects in the fasting state and at night, 72 hours before and after 8 weeks of training. Data analysis at the level of descriptive statistics using mean and standard deviation tests and at the level of inferential statistics after checking the normality of the data by the Shapiro-Wilk test. Two-way analysis of variance and Tukey's post hoc test were used. A significant level was considered in the current research (P<0.05) and all statistical steps were performed using spss25. Results: he present study showed that eight weeks of aerobic training with papaya supplementation had a significant effect on serum levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides (TG) However, there was no significant change in the level of cholesterol (TC) (P>0.05). Conclusion: Based on the results obtained from the present research, it is possible to use aerobic exercise and papaya supplement separately and especially simultaneously to improve the lipid profile of patients with fatty liver.
