IRCT20230612058457N7 IRCT 2025-06-14 Iran National Science Foundation: (INSF) Investigating the effect of flossing technique on ankle performance in athletes The effects of tissue flossing on ankle range of motion, strength, balance, and jump performance in athletes with limited ankle dorsiflexion: a randomized control trial 2025-06-24 anticipated 44 Complete https://irct.ir/trial/84055 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: In this study, individual simple randomization was performed, whereby each participant was independently assigned to either the intervention or control group. To generate the random sequence, the website www.randomizer.org was used. First, a list of eligible participants was prepared, and then the group allocation sequence was determined using the online tool provided by this website. Stratified randomization was not used in this study. To maintain allocation concealment, the random sequence was prepared by a member of the research team, and participants’ group assignments were carried out using sealed, numbered envelopes, ensuring that participants remained unaware of their group allocation until the moment of assignment. This method helps minimize allocation bias and enhances the scientific rigor of the study. 3 Limited ankle range of motion. Intervention 1: Intervention group: Participants in this group will undergo a tissue flossing intervention. In this method, an elastic flossing band is used to apply compression around the ankle joint (at 50–60% of maximum tension), while performing active movements including ankle pumps, bodyweight squats, and lunges. Each exercise is performed in 3 sets with specific durations (based on the study protocol), and the process is repeated three times per week for a period of six weeks. The aim of this intervention is to improve range of motion, strength, balance, and jump performance through mechanisms such as increased blood flow and temporary changes in fascial tissue properties. Intervention 2: Control group: Participants in this group will perform passive stretching exercises to improve ankle range of motion. These exercises target the calf muscles (gastrocnemius and soleus), with each stretch held for 30 seconds and repeated for 3 sets, with 15 seconds of rest between sets. This intervention is carried out three times per week for a duration of six weeks. The aim of this approach is to increase ankle mobility without the use of tissue compression. Yes - There is a plan to make this available What will be shared: All data will be shared after anonymizing individuals, ensuring their non-identifiability. When: The data access period will start immeduately after the results are printed. To whom: The data will be made available to researchers, organizations, and institutions related to the athletes. Conditions: In order to assist scientific research and promote the implementation of executive goals with a focus on enhancing the performance of athletes. Where to obtain: Mohammad Alimoradi/malimoradi@sport.uk.ac.ir How to obtain: Requests for access to data will be answered within a week. Comments:

This intervention is carried out three times per week for a duration of six weeks. The aim of this approach is to increase ankle mobility without the use of tissue compression. In the current study, the range of motion of the ankle joint is being investigated. Timepoint: Measurements will be taken at baseline (before intervention), as well as 6 and 12 weeks after implementing the protocol. Method of measurement: I tis measured using a goniomete. In the current study, the strength of ankle joint is being investigated. Timepoint: Measurements will be taken at baseline (before intervention), as well as 6 and 12 weeks after implementing the protocol. Method of measurement: It is assessed using an isokinetic dynamometer. In the current study, the dynamic balance is being investigated. Timepoint: Measurements will be taken at baseline (before intervention), as well as 6 and 12 weeks after implementing the protocol. Method of measurement: It is measured using the Y Balance test. In the current study, the vertical jump is being investigated. Timepoint: Measurements will be taken at baseline (before intervention), as well as 6 and 12 weeks after implementing the protocol. Method of measurement: It is measured using the Sargent jump test.
