PURPOSE: Numerous studies claim that Taekwondo can effectively help obese children improve their physical fitness. In addition, Taekwondo might help prevent lifestyle diseases and metabolic syndrome caused by obesity. However, studies and reviews on the effectiveness of Taekwondo Poomsae are very few compared to those on Taekwondo Kyorugi. Based on previous reviews, this study aims to clarify the effect of Taekwondo Poomsae training on improving body composition, physical fitness, and blood composition of children and adolescents of different groups. Furthermore, the applicability of Taekwondo Poomsae training is to be determined.METHODS: Two-hundred and two studies were searched via Korea electronic databases RISS, KISS, and DBPIA from March 1 to 3, 2021, and 22 of these were included in this review.RESULTS: Our review confirms that Taekwondo Poomsae is effective in improving the physical condition of developing children and adolescents. However, we cannot assert that this sport is also an effective exercise therapy for special youth groups, such as those who are overweight, obese, or have a metabolic growth or development syndrome.CONCLUSIONS: We suggest that sports implementers, Taekwando experts, coaches, and other sport professionals provide more Taekwondo Poomsae training programs suitable for physical and physiotherapeutic exercises for different ages and groups.
