An observational study in Physical Activities, Muscle Strength and Digital Addiction, sponsored by Ondokuz Mayıs University. Active, not recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 30 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-03-02.
Sponsored by Ondokuz Mayıs University · Observational
Results from muscle strength assessment methods commonly used in physiotherapy can vary due to their lack of objective results and their reliance on the individual's muscle strength. Digital muscle testing devices provide objective results because they provide numerical data based on the resistance applied by the individual performing the measurement. These data can objectively identify weakness in specific muscles or muscle groups that may occur due to decreased physical activity levels in university students, and they will also be useful in developing an individualized exercise program.
2,426 studies on the registry are indexed under Motor Activity; 1,161 are open to participants now.
This study's planned enrollment of 140 is above the median of 100 across 292 observational studies indexed under Motor Activity.

Lafayette Muscle Strength Devices
The Lafayette muscle strength measurement device is a digital dynamometer used to objectively and numerically assess maximum isometric muscle strength. The device provides a more precise and repeatable measurement than manual muscle testing, providing a reliable method for assessing muscle strength. It can be used with various attachments for different muscle groups and is frequently used in rehabilitation, performance analysis, and clinical research. A high score indicates high muscle strength.
Time frame: 1 year
International Physical Activity Questionnaire - Short Form (IPAQ-SF)
The IPAQ-SF is an internationally standardized self-report questionnaire developed to determine individuals' physical activity levels. This seven-question short form assesses \*\*walking, moderate-intensity, and vigorous-intensity physical activities\*\*, as well as \*\*sitting time\*\*, over the past seven days. Using participant-reported duration and frequency data, physical activity level is calculated in \*\*MET-minutes/week\*\*. Its rapid administration and applicability to large populations make it a valid and reliable measurement tool for population-based research and clinical trials. Participants can use physical activity levels of Low, Moderate, or High based on their MET score, depending on the day and time. A higher MET value indicates a higher level of physical activity.
Time frame: 1 year
Quality of Life (SF-12)
Quality of Life will assess with SF-12. The SF-12 is a short self-report questionnaire developed to assess individuals' general health status and quality of life. A shortened version of the SF-36, this scale consists of 12 questions and assesses physical and mental health components (Physical Component Summary (PCS) and Mental Component Summary (MCS). Due to its short administration time and practicality, it is frequently used in clinical research, community health studies, and rehabilitation. A high score indicates a high level of life quality. Scores range from 0 to 100. 0 points: Worst health status and 100 points: Best health status. Higher scores indicate better physical or mental health. Lower scores indicate worse health status.
