Study purpose. This study aims to analyze and highlight the potential of Sea Cucumber in reducing oxidative stress and inflammation caused by exercise. Materials and methods. The study is a type of systematic review research using searches from various journal databases such as Science Direct, Pubmed and Web of Science. The inclusion criteria in this study were journals published in the last 5 years which discussed sea cucumber, oxidative stress, inflammation and exercise. Furthermore, the exclusion criteria in this research are journals that are not reputable or are not indexed by Scopus and Web of Science. A total of 1038 articles from the Science Direct, Pubmed and Web of Science databases were identified. A total of 8 articles that met the inclusion criteria were selected and analyzed for this systematic review. For standard operations, this study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) assessment. Results. The results of this systematic review research report that the strong phenolic content found in Sea Cucumber has anti-oxidant properties which may reduce oxidative stress. Furthermore, the anti-inflammatory properties of sea cucumbers have the potential to reduce uncontrolled inflammation caused by intense exercise. Conclusions. The phenolic content in sea cucumbers has strong anti-oxidant properties in reducing oxidative stress. In addition, the anti-inflammatory properties of sea cucumbers may reduce uncontrolled inflammation caused by exercise. In this case, sea cucumbers have an anti-inflammatory effect by suppressing the secretion of pro-inflammatory cytokines. Through this systematic review, we recommend that future studies should perform clinical trials on the potential effects of sea cucumber on oxidative stress biomarkers and inflammatory biomarkers after exercise.

This study aims to analyze the effectiveness of the gymnastic learning model, which makes students more active during learning to improve students rolling skills. This type of research is an experiment with a pre and post-test design. 34 people with an average age of 15 years, consisting of 16 men and 18 women, participated in this study. Subjects were divided into two groups the experimental and control groups. They were taking research subjects using a purposive sampling technique. The control group carried out an independent study according to the instructions from the teacher, while the experimental group was treated with a play learning model according to the treatment program that had been made in each lesson. The forward roll skill test instrument uses a forward roll skill test sheet which contains a forward roll assessment indicator, which consists of 10 assessment indicators, starting from the initial phase, the primary phase, and the final phase for the forward roll movement. Data analysis was performed using the SPSS application with the Paired t-test method. This study's results reported a significant difference in the experimental group (p
