ObjectivesThe aim of this study was to investigate the effects of continuous (48-hour)
use of Kinesiotaping (KT) on functional and proprioceptive performance in
healthy, physically active men.MethodTwenty-six healthy, physically active men (21.8±2.2 years old) were randomly
allocated into two groups: 1) Kinesiotaping group (KG, tape applied with 40%
tension for rectus femoris activation); 2) Control (CG, tape applied over
rectus femoris without additional tension). Subjects attended the laboratory
on five separate occasions: 1) familiarization; 2) baseline measurement
without tape (BL); 3) immediately post-tape application (T0); 4) 24h (T24);
and 5) 48h (T48) post-tape application. The outcomes were distance in the
single (SHT) and triple hop tests (THT), vertical jump height (VJH),
vertical jump power (VJP), and rate of force development (RFD). A
mixed-model ANOVA was applied to verify differences between and within
groups.ResultsNo significant (p >0.05) differences were found in the SHT and THT between
groups and moments. Likewise, the main effects for VJH, VJP, and RFD were
not significant (p >0.05).ConclusionThe present study demonstrated no significant immediate or prolonged (48h)
effects of KT on functional and proprioceptive performance.
Context: Elastic taping has been widely used for either to facilitate or to inhibit muscle contraction. The efficacy of elastic taping is allegedly ascribed to physiological mechanisms related to subcutaneous tissue and muscle stimulation as a result of tape tension and direction. However, the underlying mechanisms that support the use of elastic taping are still unclear. Objective: To investigate changes in electrophysiological responses after 48 hours of tape application in different directions on the calf muscles of healthy individuals. Design: Within-subjects design. Setting: Research laboratory. Participants: Twenty-seven physically active males (age 18.0 [4.2] y, height 1.65 [0.07] m, body mass 62.3 [10.3] kg) participated. Interventions: Soleus H-reflex responses were evoked through stimulation of the tibial posterior nerve with 2- to 4-second interval between stimuli (32 sweeps) for each condition (baseline: without tape; facilitation: tape applied from muscle origin to insertion; inhibition: tape applied from muscle insertion to origin). Main Outcome Measures: The H-reflex amplitude values were normalized by the maximal direct response (Mmax). Parameters were estimated from a sigmoidal fit of the H-reflex recruitment curve (ascending limb). Results: No significant differences were found for the parameters derived from the recruitment curve of the H-reflex among the conditions (P > .05). Conclusions: The authors’ findings showed that, irrespective of the direction of tape application, the elastic tape applied over the triceps surae does not generate any significant alteration on the excitability of the reflex pathway for different subpopulations of motor units. The authors therefore suggest a re-examination of the current recommendations on taping direction in clinical and sports activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
