NCT07574788

Brief Summary

This study will be conducted between May and August 2026 at Aydın Adnan Menderes University, Faculty of Health Sciences, with male individuals aged 18-35. For the study, cases will first be divided into 3 groups by computer-assisted randomization.The first group will be the Flex-i bar group, the second group will be the Theraband Flex bar group, and the third group will be the Sham bar group. Group 1 will perform the exercises with the Flex-i bar, while Group 2 will perform them with the Theraband Flex bar. The control group will perform the exercises with a rolling pin.After group assignment of cases is completed, demographic information such as age, height and weight of the participants will be recorded. Then, pre-exercise assessments of the participants will be conducted. The assessment will include proprioception, reaction time, power and upper extremity performance. Following the initial assessment, each group will perform their exercises with their own exercise material. Measurements will be repeated after the exercises. Measurements will be taken three times during the assessments and the best result will be recorded.

Outcome Measures

Primary Outcomes (2)

  • Proprioception

    Joint position sense will be assessed using an inclinometer.(Baseline 12-1057 digital inclinometer)

    Immediately before and immediately after a single session intervention (within the same day)

  • Reaction Time

    Reaction time will be measured using a computerized reaction time test.(Blazepod)

    Immediately before and immediately after a single session intervention (within the same day)

Secondary Outcomes (2)

  • Power

    Immediately before and immediately after a single session intervention (within the same day)

  • Upper Extremity Performance

    Immediately before and immediately after a single session intervention (within the same day)

Study Arms (3)

A-Flexi bar

EXPERIMENTAL

For the flexi-bar exercise, the participant will be in a standing position. The participant will be shown movements in different angles and positions. Then, the participant will be given a flexi-bar and asked to hold the exercise bar and swing it correctly according to the desired movements. In flexi-bar exercises, a 1-minute rest period will be given after each exercise to account for possible fatigue.

Other: flex-i bar

B-Theraband Flex-Bar

EXPERIMENTAL

The participant will be in a standing position. The participant will be shown movements in different angles and positions. They are preferred because they increase grip strength, strengthen the upper extremities, hands and feet with bending or swinging movements, and enable soft tissue movements effectively. Blue color will be preferred for the exercise and a 1-minute rest period will be given after each exercise.

Other: Theraband Flex-Bar

C-Rolling pin

OTHER

Rolling pin; a standard size (100cm) rolling pin will be used in the control group. A 1-minute rest period will be given after each exercise.

Other: Rolling-pin

Interventions

A single session of oscillatory exercise using a Flexi-Bar applied to the upper extremity.

A-Flexi bar

A single session of upper extremity exercise using a Theraband Flex-Bar.

B-Theraband Flex-Bar

A single session of upper extremity exercise using a rolling pin.

C-Rolling pin
