Brief Summary

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.

Conditions

Muscle Fatigue and Muscle Oxygenation

Keywords

Muscle Oxygen Saturation; Muscle Strength; Instrument-Assisted Soft Tissue Mobilization (Graston Technique); Percussion Therapy

Outcome Measures

Primary Outcomes (1)

• Muscle Oxygen Saturation (SmO₂)

  Oxygen saturation will be measured with the MOXY device. It is an infrared measuring device called "near infrared spectroscopy" that measures oxygen saturation and total hemoglobin in muscle capillaries. The device will be attached to the highest point of the muscle and secured with a black sheath and tape to prevent light exposure.

  "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 Outcomes (1)

• Muscle Strength

  "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"

Other Outcomes (2)

• Pain Threshold

  "120 seconds before the warm-up or intervention" "120 seconds after the warm-up or intervention" "120 seconds after exercise"

• Perceived Fatigue

  "Baseline (180 seconds before exercise)" "Post-exercise, immediate (0 minutes)" "Post-exercise (24 hours after exercise termination)" "Post-exercise (48 hours after exercise termination)" "Post-exercise (72 hours after exercise termination)"

Study Arms (3)

instrument-assisted soft tissue mobilization

ACTIVE COMPARATOR

With the Graston method, 2 minutes of soft tissue mobilization will be performed on the biceps muscle before the exercise.

Other: Instrument-Assisted Soft Tissue Mobilization (AISM)

percussion gun

ACTIVE COMPARATOR

A percussion gun will be applied to the biceps muscle for 2 minutes before the exercise.

Other: Percussion Therapy

control

NO INTERVENTION

A 2-minute warm-up will be performed without any application.

Interventions

Percussion Therapy OTHER

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.

Instrument-Assisted Soft Tissue Mobilization (AISM) OTHER

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 minutes, and baby oil will be used to ensure the instrument moves smoothly over the skin.
