Immediate Effects of Kinesio and Dynamic Taping on Functional Performance in Adolescent Volleyball Players with Patient-Reported Ankle Instability: A Cross-Sectional Experimental Study

In the high-stakes world of competitive sports, the difference between a victory and a defeat often comes down to split-second decisions and the body's ability to react instantly. For athletes who jump, land, and change direction with explosive force, the ankle is a critical pivot point. When this joint feels unstable or gives way, it is often due to a condition known as functional ankle instability. This is not necessarily a broken bone or a torn ligament that requires surgery, but rather a lingering sense of weakness and a lack of confidence in the joint's ability to support the body during complex movements. It is a feeling that a sprain is about to happen again, even when the tissue has healed. To combat this, many athletes turn to taping, a method where elastic strips are applied to the skin to provide support. Two popular types are kinesio taping, which is designed to stimulate the skin and improve the body's internal sense of position, and dynamic taping, which aims to absorb the shock of movement and reduce stress on the tissues. The question that has long puzzled coaches and medical professionals is whether these strips actually help an athlete perform better right now, or if they simply offer a psychological comfort.

A team of researchers in Turkey set out to answer this question by looking directly at the performance of young volleyball players. Volleyball is a sport defined by vertical leaps and rapid landings, making the players particularly susceptible to ankle injuries. The study focused on adolescent athletes, a group whose bodies are still developing and whose neuromuscular control systems are maturing. The researchers recruited twenty-nine players from youth teams, all of whom had reported feelings of instability in their ankles. To ensure they were studying the right group, they used a specific questionnaire that identified players who felt their ankles were unreliable. These athletes were then divided into three groups. One group received no treatment at all, serving as a baseline to see how they performed naturally. The second group had their ankles wrapped with kinesio tape, applied by a physiotherapist to support the muscles and ligaments on the outside of the foot. The third group received dynamic tape, applied in a crisscross pattern over the same area to absorb mechanical stress.

The experiment was straightforward and immediate. Before any tape was applied, every athlete performed a series of rigorous physical tests designed to measure their power, balance, and coordination. They hopped on one leg as far as they could, performed three hops in a row, crossed over a line while hopping, and timed how quickly they could hop six meters. These tests are standard ways to gauge how well the lower body functions under pressure. Immediately after the taping was applied, the athletes repeated the exact same tests. The researchers were looking for any measurable difference in distance or speed that could be attributed to the tape. They compared the results of the taped groups against the untaped group and also looked at how each individual athlete changed from before the tape to after.

The results were clear and consistent across the board. The study found that neither the kinesio tape nor the dynamic tape provided a statistically significant boost to the athletes' performance. The players who received tape did not jump farther, hop faster, or land more stably than the players who received no intervention at all. In fact, when the researchers looked closely at the individual scores, they saw a mixed picture. Some athletes did slightly better after the tape was applied, while others performed slightly worse, and many showed no change. This lack of a uniform improvement suggests that the tape did not create a universal mechanical advantage. The researchers noted that the elastic nature of the tape allows for a great deal of movement, which might mean it simply cannot restrict the joint enough to alter the biomechanics of a high-speed hop. Furthermore, the idea that stimulating the skin would instantly improve complex muscle coordination did not hold up in this immediate timeframe.

The study also considered the unique nature of the participants. These were adolescents, whose bodies are still growing and whose movement patterns are not yet fully fixed. The researchers suggested that because their nervous systems are still developing, the way they respond to external support like tape might be different from how adults respond. The lack of improvement could also be due to the fact that the benefits of taping, if they exist, might require time to build up rather than appearing instantly. Previous research has shown similar results, where taping helps with the feeling of stability but does not necessarily translate into better scores on performance tests.

Ultimately, the findings suggest that for adolescent volleyball players with ankle instability, applying tape immediately before a game or practice is unlikely to enhance their physical performance. While the tape might offer a sense of security or perceived support, it did not make them jump higher or move faster in the tests conducted. The researchers concluded that if the goal is to improve immediate functional performance, taping should not be relied upon as a solution. Instead, the focus should remain on other methods of training and rehabilitation that build strength and control from within the body. The study serves as a reminder that in sports medicine, what feels supportive is not always what makes an athlete perform better, and that the most effective tools for improvement are often the ones that require time and effort to develop.
