“…37 Studies have shown that the taped ankle diminished muscle activity and the rate of inversion on the ankle. 17,18,38 This is also demonstrated by wearing an ankle brace, restricting dorsiflexion and plantarflexion 39,40 as compared when there is no tape applied after ground contact during drop landing for LG. 32 Due to the restriction brought about by the tape at the ankle joint, the eccentric action of the gastrocnemius is limited, therefore less energy is absorbed to control the movement, 38 and there is a decreased need to provide mechanical stability.…”

Background: Inversion ankle sprains are among the most common traumatic injuries for both men and women caused by jumping and landing activities. The ankle is protected by the static and dynamic stabilizers to reduce the incidences of injuries. Furthermore, using a non-elastic closedbasket weave taping technique is one of the common interventions to prevent it. Knowledge about the muscle activity reaction of the dynamic stabilizers upon application of tape is limited with varying results. Objectives: To determine the effect of non-elastic closed-basket weave ankle taping on the muscle activity of tibialis anterior, peroneus longus, medial, and lateral gastrocnemius on healthy individuals during jump landing on a hard, flat surface. Methods: This study is a quasi-experimental study using a pre-and post-test design. Peak amplitude muscle activity was assessed and analyzed using surface electromyography (sEMG) after landing from a jump. The pre-test was done by jump landing without tape, after which post-test data was immediately collected after applying the non-elastic closed-basket weave taping. Jump landing was done for three trials for both pre-and post-tests. A paired t-test was used to determine significant differences in pre-post taping. Results: Fifteen healthy participants were included in the study (9 females, 6 males) with a mean age of 21 + 1.03 years old and BMI of 22.74 + 1.63 kg/m 2. No significant difference was observed on peak amplitude muscle activity of the tibialis anterior (p= 0.06), medial gastrocnemius (p= 0.32), and lateral gastrocnemius (p= 0.66) after application of tape. However, a significant difference was observed in the peroneus longus after the application of tape (p= 0.05) during jump landing. Conclusion: Non-elastic closed-basket weave taping decreased the peak amplitude muscle activity of the peroneus longus during jump landing. This research suggests that tape may influence the peroneus longus, and it may or may not be detrimental in reducing the risk of ankle sprains.

“…Ankle orthoses are biomechanically designed using a wide variety of materials to control, limit, and immobilize the motion for ankle joint. This effect of jump performance may be due to a decrease in the ankle range of motion (ROM) in the sagittal plane [ 10 , 11 ], rectus femoris and calf muscle activity [ 8 , 9 , 11 ], or vertical ground reaction force (VGRF) [ 8 , 12 ].…”

Background Ankle orthotics decreases the maximal vertical jump height. It is essential to maximize jump height and minimize ground contact time during athletic performance. However, the effect of ankle orthotics on athletic performance has not been reported. We aimed to investigate the effect of ankle orthotics on squat jump (SJ), countermovement jump (CMJ), and repetitive rebound jump (RJ) performance. Methods Twenty healthy volunteers performed SJ, CMJ, repetitive RJ under no-orthosis and two orthotic conditions (orthosis 1 and orthosis 2). During SJ and CMJ, we measured the vertical ground reaction force and calculated the following parameters: jump height, peak vertical ground reaction force, rate of force development, net vertical impulse, and peak power. During repetitive RJ, the jump height, contact time, and RJ index were measured. A two-dimensional motion analysis was used to quantify the ankle range of motion in the sagittal plane during SJ, CMJ, and repetitive RJ. Results Multivariate analysis of variance and the post hoc test showed orthosis 2 significantly decreased in the vertical jump height (p = 0.003), peak power (p = 0.007), and maximum plantarflexion and dorsiflexion angles (p < 0.001) during SJ Ankle orthoses 1 and 2 did not influence to the RJ performance compared to those using the no-orthosis condition. Additionally, orthosis 2 significantly decreased the jump height at the end of repetitive RJ (p = 0.046). Conclusions These results suggest that ankle orthosis do not affect average RJ performance but should be considered when performing repetitive jumps frequently.

“…Nevertheless, ankle orthotics may have a negative impact on athlete performance in activities such as sprinting [2], cutting [3], jump landing [4,5], and vertical jumping [2]. Furthermore, there is a consensus that ankle orthotics reduces the vertical jump height [6][7][8][9][10][11][12]. This may be due to a decrease in the ankle range of motion (ROM) in the sagittal plane [10,11], rectus femoris and calf muscle activity [8, 9,11], or vertical ground reaction force (VGRF) [8,12].…”

“…Moreover, the in uence of ankle orthotics on jump performance varies depending on the sport type and competition level [10]. Most previous studies focused on the maximum jump height for static vertical jumps such as squat jump (SJ) [8][9][10] or countermovement jump (CMJ) [6][7][8]11]; hence, some studies [6,12] pointed out the difference between the experimental situation and the actual eld situation. Certainly, the maximum jump height is an essential factor for athletic performance.…”

Background: Ankle orthotics decreases the maximal vertical jump height. It is essential to maximize jump height and minimize ground contact time during athletic performance. However, the effect of ankle orthotics on athletic performance has not been reported. We aimed to investigate the effect of ankle orthotics on squat jump (SJ), countermovement jump (CMJ), and repetitive rebound jump (RJ) performance and the relationship between jump performance and restriction in sagittal ankle range of motion. Methods: Twenty healthy volunteers performed SJ, CMJ, repetitive RJ under no-orthosis and two orthotic conditions (orthosis 1 and orthosis 2). During SJ and CMJ, we measured the vertical ground reaction force and calculated the following parameters: jump height, peak vertical ground reaction force, rate of force development, net vertical impulse, and peak power. During repetitive RJ, the jump height, contact time, and RJ index were measured. A two-dimensional motion analysis was used to quantify the ankle range of motion in the sagittal plane during SJ, CMJ, and repetitive RJ. Results: Multivariate analysis of variance and the post hoc test showed a significant decrease in the vertical jump height (p = 0.003), peak power (p = 0.007), and maximum plantarflexion and dorsiflexion angles (p <0.001) during SJ using orthosis 2 compared to those using the no-orthosis condition. Additionally, orthosis 2 significantly decreased the jump height at the end of repetitive RJ (p = 0.046), during which a significant negative correlation was found between jump height and maximum dorsiflexion angle (r = 0.485, p = 0.030). Conclusions: An ankle orthosis-induced restriction of dorsiflexion is associated with a reduction in jump height during static jump and repetitive RJ performance.
