Primary purpose: TREATMENT

Brief summary: This study aims to investigate the acute effects of local vibration applied after induced fatigue of the wrist flexor muscles on grip strength and upper extremity reaction time.

Detailed description: This randomized controlled study will be conducted with a minimum of 42 participants who meet the inclusion and exclusion criteria. Participants will be randomly assigned to one of three groups: control, 50 Hz local vibration, or 100 Hz local vibration.

Eligibility criteria: Inclusion Criteria:

1. Female individuals aged 18-25

Exclusion Criteria:

1. Having an open wound in the area where local vibration is applied
2. A history of previous or current upper extremity injury
3. Use of anti-inflammatory drugs
4. Having a diagnosis of epilepsy

Primary outcomes:
measure: Hand Grip Strength Measurement
timeFrame: Change in hand grip strength from baseline following intervention or rest
measure: Upper Extremity Reaction Time Measurement
timeFrame: Change in upper extremity reaction time from baseline following following intervention or rest
Secondary outcomes:
Other outcomes:
measure: Fatigue Perception and Relief Sensation After Vibration or Rest
timeFrame: Change in baseline fatigue perception and relief sensation following intervention or rest
measure: Post-Fatigue Fatigue Rating
timeFrame: Change in baseline fatigue following muscle exhaustion protocol
