Measuring the nutritional needs of rock climbing athletes can help athletes, coaches, and managers determine the portion of food and portion of the athlete's training. The purpose of this study is to determine the energy requirements and nutritional needs of FPTI rock climbing athletes in Buleleng Regency as recommendations for feeding. This research is a cross-sectional study that seeks to reveal quantitative variables and qualitative comments involving 12 rock climbing athletes. Data collection procedures by measurement of the nutritional needs of rock climbing athletes are carried out by providing an explanation of nutritional needs and measurement procedures, measuring BMI, calculating BMR and SDA, interviews for non-sports and sports physical activities, calculating total energy needs, determining food portions, and discussing the needs and eating of athletes per day. The calculation results show that the athlete's BMI is in the ideal category. The average energy requirement of athletes per day is 4568.45 calories. The average carbohydrate requirement for rock climbing athletes is 2741.07 calories or 685.27 grams. Energy needs that can be met by fat are 1142.11 calories or 126.9 grams. The energy requirement that can be supplied by protein is 685.27 calories or 171.32 grams. Rock climbing athletes require a diet with a rather low intake of protein and carbohydrates to keep body weight low. Adolescent rock climbing athletes must be careful in managing energy consumption which has an impact on growth and achievement.

The problem that arises is the use of technology in 21st-century physical education learning. Educators are required to use technology in every lesson that is carried out, to the demands and learning outcomes. The purpose of this paper is to present the advantages and disadvantages of technology in physical education learning based on the opinions of several previous studies. The writing of this article is a literature review in nature, analyzing reports that are relevant to the use of technology in learning. Literature was obtained using the search application on Google Scholar, Science Direct, Scopus, Web of Science, and books by entering the keywords "21st-century learning", "technology" and "physical education". The literature sources used are 2013-2023. The results of a review of several articles show that technology can help physical education learning, but some argue that physical education learning cannot be done using technology because the teacher's role cannot be replaced.

The main problem is that service is only considered as the beginning of a match. When in fact service is a very important thing in a match, because service is a fast way to get points. One important part of the tennis serve is the skill of coiling or body rotation. The purpose of this service is to provide coiling exercises that are analyzed kinovea application. This service is carried out for 6 weeks with a frequency of 3 times per week. At the beginning and at the end of the meeting the partners' coiling skills were analyzed using the kinovea app. Partners are 30 South Sulawesi novice tennis athletes aged 14-16 years. The result of this dedication was an average increase in coiling skills of 1,267. So this service is necessary in improving coiling skills in order to be able to score points quickly in a match of tennis.

This study analyzes the differences between the concentration levels of the rote low-impact aerobics dance group and the video low-impact aerobics dance group. The subjects in this study were 36 adolescents aged 18-20 years who voluntarily participated. Subjects were divided ordinal pairing into two groups, namely 18 people in the rote low-impact aerobics dance group and 18 people in the video low-impact aerobics dance group. The duration of the exercise is 30 minutes sessions with an intensity of 50-70% HRmax, and the frequency of exercise is 3 times/week for 6 weeks. Concentration levels were evaluated pretest and posttest the intervention using the Grid Concentration Test. The data analysis used the Independent Sample Test with a significant level (p ≤ 0.05). The results showed that there was an increase in the average concentration between the pretest and posttest in the rote low-impact aerobics dance group (scores 6.89 ± 2.45 and 9.56 ± 2.64, p = 0.000), and the video low-impact aerobics dance group (scores 7.39 ± 2.38 and 9.11 ± 2.45, p = 0.000). Based on the pretest and posttest data it was concluded that there was an increase in the level of concentration in both groups, but there was no difference between the rote low-impact aerobics dance and video low-impact aerobics dance on concentration.
