Abstract
Study purpose. This study aims to determine the relationship between physical activity (PA), body mass index (BMI), and body fat percentage in final-year students at the junior high school level.
Methods. This research is quantitative with a correlational research design. The subjects in this study were 9th-grade students at SMP Negeri 1 Jogoroto who were selected using random sampling techniques. A total of 58 students (29 boys and 29 girls) were randomly selected and volunteered to participate in this study. PA levels were measured using the IPAQ questionnaire, body fat percentage was measured using the Tanita InnerScan Body Composition Monitor scales model BC-541, and BMI was obtained from the formula = body weight (kg)/body height² (m). The data analysis technique uses descriptive statistical tests and Spearman’s rho rank correlation with the help of Microsoft Excel 2016 and SPSS version 25.
Results. The results of the correlation test show that the correlation coefficient is negative and the significance is greater than 0.05 between PA and BMI (r = −0.162, p = 0.225 > 0.05) and body fat percentage (r = -0.095, p = 0.480 > 0.05). It can be said that these two relationships are weak, while BMI and body fat percentage have a positive correlation and significance less than 0.05 (r = 0.779, p = 0.000 < 0.05), indicating that BMI and body fat percentage have a strong correlation.
Conclusions. The conclusion is that PA is negatively correlated with BMI and body fat percentage, although neither relationship is significant. However, BMI was found to have a positive and significant correlation with body fat percentage in students. Therefore, it is recommended that students maintain their PA in line with WHO recommendations and keep their BMI within the normal range. If your BMI is normal, it is likely that your body fat percentage is also normal.

DOI: https://doi.org/10.56984/8ZG7D19FZ3B

Abstract
Study purpose. The objective of this study was to assess the effect of training at high altitudes and under hypoxic conditions on athletes’ endurance and power capabilities.
Methods. A literature review was conducted using POP software on Scopus, PubMed, and Google Scholar, focusing on studies published between 2020 and 2022 regarding altitude training and endurance. Key data extracted included author, sample characteristics, study design, training protocol, measurements, and study results. Thirteen articles were identified and analyzed to investigate the impact of low-oxygen training on athletes’ physical capacity.
Results. The literature review indicated that altitude and hypoxia training can increase anaerobic capacity, total hemoglobin mass (tHb), and peak aerobic performance in athletes. However, significant variation was observed in individual responses to such training, indicating that not all athletes respond the same way to similar training conditions.
Conclusions. Training at altitude and under hypoxic conditions can provide significant physiological benefits, but responses to this training vary among individuals.

DOI: https://doi.org/10.56984/8ZG007D4I1D

Abstract
This study aims to analyze rosella flower extract supplementation on superoxide dismutase (SOD) levels after physical activity. This experimental research uses a pre- and post-control group design. Subjects were selected using a purposive sampling technique. A total of 20 healthy men aged 19–25 years participated in this study and were divided into two groups, namely group K1 with a placebo and group K2 with rosella flower extract at a dose of 500 mg. Data collection began with gathering data on subject characteristics. Next, the subjects were asked to warm up and perform physical activity in the form of running 2400 meters at moderate intensity. One hour after running 2400 meters, blood was drawn for a pre-test to measure SOD levels. Then, supplementation interventions were administered according to the respective groups: a placebo for K1 and rosella flower extract at a dose of 500 mg for K2. Sixty minutes after the supplementation intervention, a post-test blood draw was conducted. The study’s findings demonstrated that administering 500 mg of rosella flower extract after physical exercise significantly increased superoxide dismutase levels (p < 0.05*). Furthermore, there was also a notable rise in the control group’s superoxide dismutase levels (p < 0.05*). It can be concluded that a physiological increase in SOD levels is a result of moderately intense physical activity. However, administering rosella flower extract after physical exercise is also recommended as an additional supplement to further boost the body’s antioxidant levels and maintain health.

DOI: https://doi.org/10.56984/8ZG2EF85A3

Abstract
The aim of this study was to analyze the potential of exercise massage on ischemic muscle pain and ROM after exercise. This experimental research uses a pre and post control group design. Research subjects were selected using purposive sampling technique. Next, the subjects were divided into 2 groups, namely group (K1) which was not given special treatment and group (K2) which was given sports massage. A total of 18 healthy men participated in this study. Our first procedure is preparing research administration and permission to borrow facilities and infrastructure. Next, we screened respondents who were used as research subjects based on inclusion and exclusion criteria and filled out Informed Consent. On the day of the research, all subjects collected data on the characteristics of the research subjects, then warmed up, and then the subjects did exercises in the form of treadmill training with an intensity of 50-60% of their maximum ability. The intensity of the exercise was monitored using a polarizer. Exercise is carried out for 15 minutes. 30 minutes after exercise, all subjects had pre-test data taken to measure ischemic muscle pain and Range of Motion. After collecting pre-test data, subjects carried out interventions based on their respective groups. After being given the intervention, the subject carried out post-test data collection. The intensity of ischemic muscle pain was measured using VAS and ROM was measured at the knee joint using a goniometer. The results of our study reported that the group given exercise massage was able to reduce the intensity of systemic muscle pain and increase ROM significantly (P < 0.05). Providing sports massage after exercise can reduce ischemic muscle pain and increase ROM. Considering that pain intensity and ROM are necessary to support body function, our research findings can be used as an alternative to support physical performance.
