There are a limited number of studies in the literature, and it is stated that mental fatigue caused by social media use causes a decrease in upper-extremity movement speed and a decrease in lower-extremity endurance performance. Therefore, this study aims to determine the effects of social media-induced mental fatigue on upper extremity performance.
Mental fatigue is a psychobiological condition that requires prolonged cognitive activity and is characterized by subjective feelings of "tiredness" and "lack of energy." It reduces sport-related decision-making, technical skills, motor control and endurance performances. This has led to a condition known as social media fatigue among many users, where they feel exhausted from repeated exposure to an enormous amount of information from brands. Social media fatigue is "the tendency of social media users to withdraw from social media when they are overwhelmed by too many social media sites, too many friends and followers, and too much time spent online to maintain these connections".Researchers have drawn attention to the negative effects of internet-induced fatigue, which is increasing daily, and emphasized that excessive internet use can lead to physical and psychological problems. Although there are a limited number of studies in the literature, there is a limited number of studies investigating the effects of mental fatigue caused by social media use on upper extremity performance.Therefore, this study aims to determine the effects of mental fatigue caused by social media on upper extremity performance.

| Social Media Fatigue | Other | Mental Fatigue creation protocol: It has been reported that at least 30 minutes of social media use causes mental fatigue and impairs lower extremity and decision-making performance (Fortes et al., 2021). For mental fatigue with social media, participants will be created with 45 minutes of continuous use of social media (instagram, facebook, twitter, youtube) on smartphones by concentrating with headphones. |
| Measure | Description | Time Frame |

| 1-Isometric Elbow Flexion Strength | The participant will sit in a chair with upper arms at their sides, elbow bent 90 degrees, and forearm supinated. A velcro strap attached to a digital dynamometer fixed to a portable wooden platform placed under the chair will be secured tightly around the participant's wrist, proximal to the distal wrist crease. The tester will check the strap's tension to ensure no slack. When instructed, the participant will endeavor to move their hand as forcefully as possible towards the shoulder for 2-3 seconds. Any compensatory movement in trunk extension or lateral flexion outside the tested arm will be observed. | Baseline |

| 2-Hand grip strength | Hand grip strength will be assessed using a Jamar hand dynamometer (Lafayette Instrument Company, USA). The participant will sit holding the dynamometer with the upper arm at the side, elbow bent 90 degrees, and forearm centered between pronation and supination. When instructed, the participant will squeeze the dynamometer as forcefully as possible for 2-3 seconds while the tester verbally encourages. | Baseline |

| 4-Finger reaction test | The participant will be asked to place the dominant hand's index finger on the left button of a computer mouse and press the left button as soon as the green lights up on the traffic light shape on the screen. The time between the light stimulus and the participant's reaction will be recorded in milliseconds. | Baseline |

| 6-Mental stopwatch | The Nine Hole Peg Test (9-DPT) was used to assess the temporal correspondence between actual and imagined movement. The 9-DPT will be administered according to standard protocols. The participant performed the test according to the standard 9-DPT protocol, during which the stopwatch will be started, and the time from the beginning to the end of the test will be recorded. In the imagined 9-DPT, a mental stopwatch will be used, and the same test will be performed with the individual visualizing the same activity while sitting with his/her eyes closed (Allali, 2012). | Baseline |

| 7-Evaluation of position sense | In the study, a Baseline® digital goniometer with a sensitivity of 1° will be used to assess the glenohumeral joint position sense. The tested person will be asked to perform shoulder flexion at 55°, 90° and 125° and to lift the arm from the position adjacent to the body to the angles mentioned (Balke et al., 2011). | Baseline |

| 8-Upper extremity endurance test: | After weighing the body weight, the weight in the hand will be calculated as 2% of the body weight and rounded to the nearest 0.5 kg if it is fractional. The participant will hang from the bed with his/her arm out. He/she should then take the weight in his/her hand and lift it with the "thumb pointing upwards" and the arm at 90° to the horizontal. A metronome set to 60 Hz will then be used to standardize the test, whereby participants will be instructed to raise their arm on the first beat, hold it at 90 abductions for the next beat and then lower it to the starting position on the third beat. The test will be terminated by fulfilling any of the following termination criteria (Moore, Uhl, & Kibler, 2013). | Baseline |
