A similar study was done by Mondal (2015), the results show that Bangladeshi youths outperform Indian youths in terms of lower-body dynamic strength (standing broad jump) and cardiorespiratory fitness (cooper reduced test). Chan et al. (2016) compared the muscle strength and endurance components of Hong Kong and international elite athletes (Norwegian, French, and Scandinavian), finding that Hong Kong athletes had less leg muscular strength and endurance than the three countries. Finally, the researchers recommend that strength and conditioning specialists create customised training programmes for Hong Kong athletes. ...
The purpose of the research was to investigate the health-related physical fitness of youth athletes from Bangladesh and India. The forty athletes from each country, Bangladesh (n=40) and India (n=40) were chosen using a simple random sampling method. The researchers selected Bangladeshi athletes from the Jashore district in Bangladesh and Indian athletes from the Murshidabad and Birbhum districts of West Bengal, India. Those who competed in at least one district-level competition were included in the study. For the study, the researchers chose male athletes between the ages of 17 and 21 years. The study included lower body explosive strength in the standing broad jump test, upper body muscular strength in the pull-up test and cardio-respiratory endurance in the cooper test as variables. The data was analysed using descriptive and inferential statistics (independent t-test), with the significance level set at 0.05. An independent sample t-test shows that Bangladeshi and Indian youth athletes standing broad jump t(78) = 2.10, sig. = 0.039; pull-ups t(78) = 1.68, sig. = 0.099; cooper test t(78) = 2.34, sig. = 0.022 respectively. The findings revealed a substantial difference in leg explosive strength and cardio-respiratory endurance, but no substantial difference in upper body muscular strength between Bangladeshi and Indian youth athletes.

Research purpose. Football is popular in the society across the world. Everyone always watches football matches. Nowadays, there are many football schools for kids or young athletes. Thus, there is a need for a model of exercise that is appropriate for young athletes. This study aimed to create a model of group defense exercise in a football game. It referred to 13-year-old football school students. It was designed using psychological and physiological characteristics of the 13-year-old.
Materials and methods. The study participants were 120 football players aged 12 to 13. The study used a research and development method (R&D) through Borg and Gall model. Data was obtained from observation, interview and questionnaires. Data analysis techniques used expert judgments and three steps from Miles and Huberman, namely reduction of data, display of data, and making conclusions.
Results. The findings show that the model of defense exercise in football for a 13-year-old football school player has 13 variations of the exercise. It was created based upon the psychological and physiological characteristics of a young player.
Conclusions. The result of the study is a recommendation for teachers or coaches to improve the defense exercise in football as player needs.
... This is characterized by a decrease to the loss of muscle contraction ability in a certain period. Muscle fatigue refers to reducing muscle response to a stimulus (Chan et al., 2016). According to Burleigh et al., (2020) muscle fatigue that occurs in high-intensity exercise is caused by several factors, including high levels of acidity due to increased production of lactic acid; inadequate concentrations of blood glucose, liver glycogen and muscle glycogen for energy production; and the inadequacy of food and drinking arrangements before and during the exercise (Temesi et al., 2011). ...
Muscle fatigue is a common problem experienced by athletes when undergoing exercise. Sports snacks are an effective solution for preventing them because they can be consumed between workouts without requiring a particular time. However, the availability of sports snacks is still rarely traded in the market. The purpose study is to produce a nastar based on a mixture of banana flour and tempeh (named B-Star Snack) as a sports snack that can prevent muscle fatigue. The research was carried out in July - December 2020 at the Food Technology Lab, Department of Nutrition, Denpasar Health Polytechnic, where wheat flour as the main ingredient for making nastar was substituted with tempeh flour and banana flour with the five combinations of banana flour and tempeh mixtures. All observations were analyzed by ANOVA. Especially for the results of the organoleptic test, in order to meet the assumption of a normal distribution, the data is transformed into an interval scale using the successive interval method. There was a significant difference in the preference for B-Star Snack between formulas (p = 0,014). The most preferred is the combination of tempeh and banana flour (40:60%). The B-Star Snack with a 40:60% combination contains the complete nutrition of both macro and micronutrients. The B-Star Snack with a tempeh and banana flour 40:60% as much as 100 grams per serving can be recommended to prevent muscle fatigue due to the exercise.

Athletes who boarded have an organized eating arrangement, so the dietary intake is more assured. The objective of this study was to analyze the differences of energy, macronutrients intake, nutritional status, and V2 max between boarding and nonboarding football athletes aged 13 - 18 years. A cross-sectional study was done in 32 people who divided into two groups (boarding and non-boarding football athletes).The collected datas included food intake using 6x24 hoursfood recalls, height using microtoise, weight using digital scales, BMI for Age using WHO Anthro Plus, body fat percentage using Bioelectrical Impedance Analysis, VO2 max using Cooper Test 2.4 km. Nutrient values were analyzed using NutriSurvey. Statistical analysis using Independent TTest. There were significant differences between energy and macronutrient intake (p=0.001), body fat percentage (p=0.004), and VO2 max score (p=0.001) of boarding and non-boarding athletes. Energy and macronutrient intake of boarding and non-boarding athletes were still in the deficient category; however, the average nutritional intake of boarding athletes were still higher than non-boarding athletes. Most nutritional status of athletes based on BMI/Age were in normal category (87.5% in boarding athletes and 62.5% in non-boarding athletes). There was no over in non-boarding athlete. However, there were 12.5% of boarding athletes in the over fat category. 25% of non-boarding athletes were in the under fat category, while in boarding athletes, none of athlete in under fat category. 62.5% boarding athletes had VO2 max score at a very good level, while 87.5% of non boarding athletes were in enough category.
