Official title

Comparison of the Effects of Pre-Exercise Instrument-Assisted Soft Tissue Mobilization and Percussion Therapy on Muscle Using a Crossover Design

Overview

The study aims to investigate the effects of percussion therapy and instrument-assisted soft tissue mobilization (AISM), commonly used in clinical settings, on muscle fatigue, maximum muscle strength, pain threshold, and muscle oxygenation. The study will involve 20 volunteer participants. To achieve the study results, pre-exercise percussion therapy and instrument-assisted soft tissue mobilization (AISM) will be administered using a crossover design. Results will be measured using a digital dynamometer, a moxy oxygen monitor, and a fatigue questionnaire.

Interventions

  • Other Percussion Therapy
    The massage gun will operate at a frequency of 30 beats per second (30 Hz), and percussion therapy will be applied to the muscle for 2 minutes. Percussion therapy will be performed using the device's standard ball head. The force applied by the device will be fixed so that it does not exceed the device's first-stage force setting (approximately 30 pounds). The biceps brachii (dominant arm) will be treated for 2 minutes at 30 Hz, moderate intensity.
  • Other Instrument-Assisted Soft Tissue Mobilization (AISM)
    The arm will be positioned at the edge of the bed in full extension, with the shoulder in 45-degree abduction. The examiner will apply gentle pressure using a 30-degree angled instrument at a rate of 120 strokes/min, aligning the instrument's weight with the fibers of the biceps brachii muscle. The examiner will use a metronome to maintain a consistent pace during treatment, and the instrument angle will be calibrated with a protractor before each subject's treatment. The procedure will last 2 m

Primary outcome measures

  • Muscle Oxygen Saturation (SmO₂) [Time frame: "Baseline (30 seconds before exercise)" "During the entire exercise period (from exercise onset to exercise termination)" "Post-exercise (0 to 2 minutes after exercise termination)"]
Secondary outcome measures (1)
  • Muscle Strength [Time frame: "30, 60, and 90 seconds before the warm-up or intervention" "30, 60, and 90 seconds after the warm-up or intervention" "30, 60, and 90 seconds after exercise"]
