While there is a consensus among researchers that warm-up practices positively influence sports performance, there remains ongoing de- bate about which specific stretching techniques during the warm-up phase are most effective. This study aims to investigate the effects of static and propri- oceptive neuromuscular facilitation (PNF) stretching techniques, applied dur- ing the warm-up phase over an 8-week period, on the anaerobic power and static balance performance of professional taekwondo athletes. Material and Methods: This cross-sectional study included 30 voluntary taekwondo ath- letes aged between 18-25 years. The vertical jump test was used to measure anaerobic power performance, while the flamingo balance test assessed bal- ance performance. The collected data were analyzed using IBM Statistics soft- ware. Results: In this study, there was no statistically significant difference between the balance and anaerobic power performances of taekwondo ath- letes, neither in the pre-test and post-test scores, nor between the groups (p>0.05). Therefore, it can be concluded that 8 weeks of static and PNF stretching techniques during the warm-up phase did not directly affect the anaerobic power and balance performance of taekwondo athletes. Conclu- sion: In conclusion, the findings highlight that neither static stretching nor PNF stretching alone is sufficient to elicit improvements in anaerobic power and balance performance in professional taekwondo athletes during the warm- up phase. Future research could refine warm-up protocols for taekwondo ath- letes by combining stretching and activation strategies, building on these findings.en10.5336/sportsci.2024-105905info:eu-repo/semantics/openAccessBalancestatic stretchinganaerobic powerWarm-updynamic stretchingArticle17135421305910
