“…By contrast, the absence of tension in the NT group and the wave pattern of the kinesio tape in the KT group facilitated further stretching. Notably, the present results conflict with the findings of Obst et al 40 that deloading tape lessens fascicle shortening during ankle plantar flexion 40 . However, in Obst et al 40 , the KT was applied in a diamond shape rather than a Y shape, as in the present study, and the ultrasound transducer was positioned above the taped skin.…”

However, in Obst et al 40 , the KT was applied in a diamond shape rather than a Y shape, as in the present study, and the ultrasound transducer was positioned above the taped skin. During the lunge task, the PA showed a significant increase (Z = − 2.67, p = 0.008) after fatigue induction in the ST group at the beginning of the eccentric phase and a significant reduction (Z = − 2.40, p = 0.016) after fatigue induction in the KT group at the end of the concentric phase.…”

“…Overall, the KT during movement generated an appropriate dynamic pressure variation and sufficient periodic compression and decompression of fascia layer. As a result, the magnitude of myofascial loads was distributed locally, thereby impairing the mechanics of activated muscles in a significant way 21 , 40 . The heel-rise fatigue protocol caused the FL to lengthen at the end of the concentric phase of the badminton lunge movement in all three groups (NT, KT and ST).…”

“…Therefore, in 2018, Cimino et al made an effort to detect a possible pathway for functional benefits of KT application by using ultrasound to observe all edges of KT during neutral, flex and extended spine posture 22 . Making use of the ultrasound to discover the area under the skin in real-time, Obst et al in 2019 was able to examine the medial gastrocnemius muscle fascicle during heel rise exercise after applying the diamond shape taping around the ultrasound probe 40 . However, both studies using ultrasound only investigated the area near the tape which may not explain the real mechanism underneath KT.…”

Kinesio taping (KT) is widely used in sports for performance improvement and injury prevention. However, little is known of the behavior of the muscle region beneath the KT with movement, particularly when the muscle is fatigued. Accordingly, this study investigated the changes in the medial gastrocnemius muscle architecture and fascia thickness when using KT during maximum isometric plantar flexion (MVIC) and badminton lunges following heel rise exercises performed to exhaustion. Eleven healthy collegiate badminton players (4 males and 7 females) were recruited. All of the participants performed two tasks (MVIC and badminton lunge) with a randomized sequence of no taping, KT and sham taping and repeated following exhaustive repetitive heel rise exercise. In the MVIC task, the fascia thickness with the medial gastrocnemius muscle at rest significantly decreased following fatigue induction both without taping and with KT and sham taping (p = 0.036, p = 0.028 and p = 0.025, respectively). In the lunge task, the fascia thickness reduced after fatigue induction in the no taping and sham taping trials; however, no significant change in the fascia thickness occurred in the KT trials. Overall, the results indicate that KT provides a better effect during dynamic movement than in isometric contraction.

“…However, no change of MG and LG motoneuron excitability was potentially related to no change in the form of muscle fascia and/or somatic components. Our finding was supported by a recent study showing no change in length of MG muscle fascia when diamond deloading tape was applied with and without stretch [ 30 ]. Additionally, de Jesus et al [ 31 ] showed no difference of KT effect on quadricep isometric strength and single hop performance in healthy adults when paper-off, 50%, 75%, and 100% KT maximal stretch tensions were applied.…”

This study examined the acute effects of stretch tensions of kinesiology taping (KT) on the soleus (SOL), medial (MG), and lateral (LG) gastrocnemius Hoffmann-reflex (H-reflex) modulation in physically active healthy adults. A cross-over within-subject design was used in this study. Twelve physically active collegiate students voluntarily participated in the study (age = 21.3 ± 1.2 years; height = 175.6 ± 7.1 cm; body weight = 69.9 ± 7.1 kg). A standard Y-shape of KT technique was applied to the calf muscles. The KT was controlled in three tension intensities in a randomised order: paper-off, 50%, and 100% of maximal stretch tension of the tape. The peak-to-peak amplitude of maximal M-wave (Mmax) and H-reflex (Hmax) responses in the SOL, MG, and LG muscles were assessed before taping (pre-taping), taping, and after taping (post-taping) phases in the lying prone position. The results demonstrated significantly larger LG Hmax responses in the pre-taping condition than those in the post-taping condition during paper-off KT (p = 0.002). Moreover, the ΔHmax/Mmax of pre- and post-taping in the SOL muscle was significantly larger during 50%KT tension than that of paper-off (p = 0.046). In conclusion, the stretch tension of KT contributes minor influence on the spinal motoneuron excitability in the triceps surae during rest.

An eccentrically lengthening, energy-absorbing, brake-driven model of hamstring function during the late-swing phase of sprinting has been widely touted within the existing literature. In contrast, an isometrically contracting, spring-driven model of hamstring function has recently been proposed. This theory has gained substantial traction within the applied sporting world, influencing understandings of hamstring function while sprinting, as well as the development and adoption of certain types of hamstring-specific exercises. Across the animal kingdom, both spring- and motor-driven muscle–tendon unit (MTU) functioning are frequently observed, with both models of locomotive functioning commonly utilising some degree of active muscle lengthening to draw upon force enhancement mechanisms. However, a method to accurately assess hamstring muscle–tendon functioning when sprinting does not exist. Accordingly, the aims of this review article are three-fold: (1) to comprehensively explore current terminology, theories and models surrounding muscle–tendon functioning during locomotion, (2) to relate these models to potential hamstring function when sprinting by examining a variety of hamstring-specific research and (3) to highlight the importance of developing and utilising evidence-based frameworks to guide hamstring training in athletes required to sprint. Due to the intensity of movement, large musculotendinous stretches and high mechanical loads experienced in the hamstrings when sprinting, it is anticipated that the hamstring MTUs adopt a model of functioning that has some reliance upon active muscle lengthening and muscle actuators during this particular task. However, each individual hamstring MTU is expected to adopt various combinations of spring-, brake- and motor-driven functioning when sprinting, in accordance with their architectural arrangement and activation patterns. Muscle function is intricate and dependent upon complex interactions between musculoskeletal kinematics and kinetics, muscle activation patterns and the neuromechanical regulation of tensions and stiffness, and loads applied by the environment, among other important variables. Accordingly, hamstring function when sprinting is anticipated to be unique to this particular activity. It is therefore proposed that the adoption of hamstring-specific exercises should not be founded on unvalidated claims of replicating hamstring function when sprinting, as has been suggested in the literature. Adaptive benefits may potentially be derived from a range of hamstring-specific exercises that vary in the stimuli they provide. Therefore, a more rigorous approach is to select hamstring-specific exercises based on thoroughly constructed evidence-based frameworks surrounding the specific stimulus provided by the exercise, the accompanying adaptations elicited by the exercise, and the effects of these adaptations on hamstring functioning and injury risk mitigation when sprinting.
