The aim of this research is to analyze and evaluate various research findings regarding the effect of the Bosu Ball training method on improving athletes' balance. This type of research is a literature review. Search for this article through the database on Google Scholar with the keywords 'bosu ball' and 'balance'. Based on this search, 5 articles were found (2022 – 2023) that matched the keywords and were worthy of analysis and evaluation. The results of the literature review analysis show that the Bosu Ball training method has consistently proven effective in improving athletes' balance. Then form flexible exercises using a bosu ball, such as using a circuit or combining it with other types of exercise. However, based on the evaluation of the discussion of each research result, it seems that training using the bosu ball is only an additional exercise or not as the main exercise. So the recommendation from the results of this research is to apply bosu ball training by combining other types of training that have characteristics such as strength training, speed training or endurance training, and you can also modify the number of sets or repetitions. The hope is that the physical abilities of other athletes will increase. Further research is also needed to strengthen these findings and further explore the potential benefits of Bosu Ball in improving athletes' physical abilities other than balance as well as the positive impact on athlete performance in various types of sports.
