The test of the sprint running skills of the University of Muhammadiyah Surakarta (UMS) Rugby athletes is the analysis of this study, where the athletes tested are athletes who play as defenders. In this research, the type of research used is quantitative research with ex post facto methods. Collecting research data using valid tests. Then analyzed with categorization and SPPS to determine the average running speed of rugby athletes. The results showed that two athletes were in poor condition, two were in the moderate category, three were in high condition, and three were in excellent condition. Meanwhile, the average running speed of all athletes is in the moderate category.

Abstract

Starting or continuing physical activity, especially for non-athletes, can be a challenge due to muscle injuries caused by physical activity. Therefore, the present study aimed to investigate the short-term effect of beta-hydroxy beta-methyl butyrate (HMB) supplementation on muscle and liver damage caused by a period of resistance activity in non-athletic females. Among the volunteers, 16 female non-athletes with an average age of 21.75±1.18 years, a body mass index of 24.83±2.67 kg/m2, and a weight of 63.43±8.46 kg were randomly selected as a statistical sample. The subjects were randomly divided into two groups of eight people, HMB supplement and placebo. Daily and for six days, the subjects of the supplement group received 3 mg of beta-hydroxy beta-methyl butyrate powder. The placebo group received 3 grams of starch in tablet form. After six days of loading, the subjects performed a resistance activity session with an intensity of 75-80 percent 1RM. Blood samples were taken in five stages, including before supplementation, before training, immediately, 1 hour, and 24 hours after sports activity. To compare the results, a 5x2 analysis of variance test was used. The results showed that the consumption of HMB supplements significantly affected the serum levels of Creatine kinase (CK) and lactate dehydrogenase (LDH) enzymes in the blood and the amount of aspartate aminotransferase (AST) and alanine aminotransferase enzyme activity in the blood of intragroup interactions (p less than 0.05). On the other hand, there was no significant difference between the serum levels of CK enzyme and the activity of ALT and AST enzymes between the two supplement and placebo groups (p more than 0.05). There was no significant difference in the serum level of LDH enzyme between the two supplement and placebo groups (P less than 0.05). Although the results of the present study showed that consuming 3 grams of HMB supplement reduces the LDH response after resistance training, this supplement cannot be used as an independent factor for reducing muscle damage markers following intense physical activities. As a new achievement, it is recommended that HMB supplements be taken more cautiously to reduce indicators of muscle damage.

Abstract

Changes in the level of teacher competency are continually improved through evaluation, ensuring that the learning that is applied to students remains innovative. The goal of this study was to discover physical education teachers' self-evaluation of teaching effectiveness. This study is descriptive that employs the survey approach. Fifty-one elementary school physical education teachers in South Sulawesi Province (aged 20 to 58 years) volunteered to participate in this study. The Self-Evaluation of Teacher Effectiveness Questionnaire in Physical Education (SETEQ-PE) was utilized in this study to assess teacher effectiveness in teaching physical education. This efficacy is measured using six components: learning environment, teacher and student evaluation, application of learning content, use of technology, teaching methodologies, and lesson execution. The findings revealed that the overall average physical education teachers' teaching effectiveness score was in the high range (140). In terms of gender, male instructors have a high average score (139.5), whereas female teachers have a very high average score (139.5). (142). Even though female teachers have a higher score than male teachers, there is no significant difference in their scores, with a significance value of 0.731. Given the small sample size of this study, additional research should be undertaken on a broader scale to investigate other aspects that may influence teaching effectiveness.

Abstract

Instillingnoble values in sports at school, especially physical education subjects, is not optimal at the high school level because of its unstable nature. The problem in research is that many students still do not have a sportsmanlike attitude when they accept defeat. Besides, they do not have a sense of responsibility and discipline in the group during practical subjects. The purpose of this study was to determine the contribution of the noble values of sports to the attitude of responsibility and discipline. This study uses a quantitative method which is quantitative with a regression test. The population and the sample are 60 random students. In calculating the regression coefficient, the value is positive, and the result of the equation in the constant is 22.191, which means that the consistency value is 22.191. With a contribution of 17.00 percent. This study concludes that the noble value in sports on affective responsibility and discipline shows an outstanding category.

Abstract

The problem in this study is that the portion of mental training given to athletes is not well designed. The results of the athlete's performance are much less consistent with what was found that motivational factors were the cause of weak drive during the practices. This research aimed to establish the motivation of Riau Gymnastics athletes. The population consisted of 16 gymnastics athletes in Kuantan Singingi Regency using a total sampling technique of 16 athletes. The instrument used in this research is a questionnaire. Based on the results of the questionnaire, it was determined that the performance score percentage of two athletes (12.50 percent) was in the excellent category, eight athletes (50 percent) were in the high category of motivation, and one athlete (6.25 percent) had poor motivation. Based on the average score, the motivation of the Riau Gymnastics athletes to face the Porprov X Kuantan Singingi is in the moderate category because the psychological aspects are not paid enough attention to by the coach when coaching the training program.
