Abstract: Background: Energy requirement (ER) for a competition day depends on the amount of energy consumed. Planning energy intake strategies is particularly important for decathlon athletes, who compete in track and field events over two days. However, few studies have reported how decathletes manage their energy intake. The aim of this study was to estimate the total energy intake (TEI) and total energy expenditure (TEE) of decathletes during competition days, considering with specific factors related to energy balance (EB). Methods: Eight athletes were analyzed who completed the decathlon in official track and field events. The TEI was calculated using photographs of all the food and beverages consumed by the athlete. TEE was estimated using a triaxial accelerometer-based method. The EB was calculated by the difference between TEI and TEE. Results: Over the two competition days (48 hours), the TEE for decathlon athletes was 7,984±202 kcal, with a negative EB observed on Day 2. The physical activity level (PAL) exceeded 2.3 on each day of the competition. EB was more strongly associated with TEI/kg than with TEE/kg, and was negative on Day 2. Conclusion: Competition days for decathlon athletes involve high intensity exercise. On Day 2 of the competition and the following competition day, there might be an energy deficiency. It is necessary to focus on strategies for energy intake after the competition ends in the future.

Abstract: Introduction: A goal kick is awarded when the whole of the ball passes over the goal line, on the ground or in the air, having last touched a player of the attacking team, and a goal is not scored. The purpose of this study was to find out the relationship of selected angular kinematic variables with the performance of goal kick technique of soccer goalkeepers in Ethiopia's higher premier league. Method: Purposive sampling technique was used for choosing highly skilled goalkeepers. In the present study, a total of seventeen male goalkeepers (18 to 30 years of age) who had participated in the Ethiopian premier league participated. Goal kick technique was divided into three phases, such as the stance phase, the execution phase and the follow-through phase. All goalkeepers were given three trials and the best trial was used for analysis. Each participant performed three goal kicks with maximum strength that were video recorded with a camera (nikon d3200) positioned 9 m away from the place of the kick at the height of 0.95m. The silicon coachpro 7 and kinovea software were used for analyzing the data. The Joint Point Method was used in order to obtain the values of selected angular kinematic variables by developing a stick figure. The height of the Center of Gravity was calculated by segmentation method. The relationship of selected angular & linear kinematic variables with the performance of goal kick soccer goalkeeper was obtained by spearman rank correlation method. Conclusion: During stance phase, hip joint (left and right), ankle joint right, shoulder joint right and elbow joint left, do have a significant relationship with the performance of goal kick in soccer goalkeeper. At the time of execution phase, angular kinematic variables such as ankle joint left, hip joint right, shoulder joint right and elbow joint right do show a significant relationship with the performance of goal kick in soccer goalkeeper. Whereas the elbow joint left and wrist joint left were insignificant relationships. At the time of follow-through phase, ankle joint right, elbow joint left and hip joint were significant.

Abstract: A sports coach is a total package individual who is competent and well-equipped for the role we are demonstrating. Coaches with the best level of training and the most years of experience in the sport have invested more in their education and are better at adjusting the content of the training to the developmental stages of children and adolescents. The main purpose of the study is to explore the experiences of PE teachers is sports coaching in times of COVID-19 Pandemic. On the professional aspect, the informants were able to bring their MAPEH teaching skills into practice in their own municipalities and provinces. As a result of the researcher's inability to travel, online communication and interviews were used as data collection methods to elicit the informants' experiences. This part includes the presentation, analysis, and interpretation of data gathered from the six informants from Guimaras, Aklan, Iloilo City, Ajuy, Potatan, and Pavia. It includes (1) Adversities of COVID-19 Pandemic with sub-themes of learning and training modalities and versatility of sports coaching strategies and styles (2) The Resiliency in Virtual Hubs with sub themes of life cycle on social media and (3) Discernments in the Midst of Global Dilemma with subthemes of internal enthusiasm and mind setting. Encouraging athletes to reset their mindsets to see quarantine as a learning opportunity, organizing suitable guidance, educating and motivating athletes to use proper preventive behavior, and establishing acceptable living isolation conditions. Some types of circuit-based body mass resistance training may aid aerobic adaptation. The athlete's needs should be taken into account when organizing sports skills training. The acronym AGAMER was a practical and feasible intervention that can be used by any PE teacher and coach in their respective field of expertise.
