Purpose: This study examined how low-dye tape and navicular sling kinesiotape impacts athletic performance in fatigue conditions in basketball athletes with flat feet. Methods: The current research was conducted on 12 professional basketball players aged 18 to 25 years with flat feet. The Staheli Index, Y Balance test, 20-meter speed test, modified t-test, and Sargent test were employed to assess flat feet, dynamic balance, speed, agility, and power. A basketball-specific performance fatigue protocol was used to induce performance fatigue, and treatments included low-dye taping and navicular sling kinesiotape. Results: Statistical analysis indicated that low-dye taping significantly improved dynamic balance in both fatigued (P=0.01) and non-fatigued (P=0.01) conditions (F=18.33). Additionally, performance fatigue negatively affected dynamic balance in both low-dye taping and non-taping conditions (P=0.01). It also led to impaired performance in the 20-meter speed test in the low dye and Kinesiotape conditions (0.49 and 0.60), as well as a 3.75 cm reduction in the Sargent test in the non-taping condition. Additionally, the low-dye taping condition led to a 0.68-second decrease in agility performance. Conclusion: While fatigue did have an impact on performance, low-dye taping, and Navicular Sling Kinesiotape resulted in a smaller performance decline compared to non-taping conditions. In addition, low-dye taping had a greater effect on performance and flat foot than Navicular Sling Kinesiotape. It is recommended that basketball players with flat feet use low-dye taping and Navicular Sling Kinesiotape.
