What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
physical examinationOther
Sarcopenia assessment: The SARC-F questionnaire is a screening tool developed by Malmstrom and Morley in 2013, used to assess sarcopenia in older adults. This scale evaluates difficulties experienced by older individuals across five components: strength, assistance with walking, rising from a chair or bed, climbing stairs, and falls. Each item is scored on a scale of 0-2 (0: none, 1: some, 2: a lot). For the item regarding falls, however, the scoring is as follows: 0: none, 1: one to three times, and 2: four or more times. The total score on the scale ranges from 0 to 10. A score of four or higher indicates that an individual is at risk for sarcopenia. A study on the Turkish validity and reliability of the scale was conducted by Bahat et al. in 2018. Permission to use the scale was obtained from the corresponding author.
physical examinationOther
Handgrip strength: This is a measure used to assess muscle strength and serves as a primary criterion for probable sarcopenia, according to the EWGSOP2 (European Working Group on Sarcopenia in Older People 2) guidelines. Grip strength will be measured separately for each hand using a standard hand dynamometer (Baseline brand, 200 lb LITE hydraulic hand dynamometer). During the measurement, the participant will be seated with their shoulder in adduction and neutral rotation, the elbow flexed at approximately 90°, the forearm in a neutral position, and the wrist in slight extension. Three measurements will be taken for each hand, with short rest intervals between them; the mean of these measurements will be used for analysis.
physical examinationOther
Five-times-sit-to-stand test: This is a fundamental method for measuring muscle strength-assessing lower-extremity muscle strength, functional capacity, and fall risk-that serves as an alternative or a complement to handgrip strength, in accordance with EWGSOP2 criteria. The purpose of the test is to measure the strength and endurance of the lower-extremity (leg) muscles. The individual crosses their arms across their chest and stands up from-and sits back down on-a chair of standard height, without using their hands for assistance. The time required to complete five consecutive full sit-to-stand cycles is recorded in seconds using a stopwatch. According to the EWGSOP2 consensus, a duration of more than 15 seconds for these 5 repetitions is considered an indicator of low muscle strength (probable sarcopenia).
physical examinationOther
4-meter walking speed: The 4-meter walk test is a practical assessment used to gauge an individual's general health status, physical fitness, and the rate of biological aging. Speed is determined by dividing the 4-meter distance by the time taken to cover it, expressed in meters per second (m/s). During the test, the individual walks 4 meters along a flat path at a normal, comfortable pace, while the time elapsed is measured in seconds using a stopwatch. The calculation follows the formula: Speed = 4 ÷ Time Elapsed (in seconds). For instance, walking 4 meters in 4 seconds results in a speed of 1.0 m/s. Completing the 4-meter distance in more than 5 seconds (a speed below 0.8 m/s) is considered a slow walking pace and may indicate potential health risks-such as an increased risk of falls, muscle loss (sarcopenia), cognitive decline, or other general health issues. Speeds of 1.0 m/s or higher generally indicate a healthy and normal level of functional capacity.
| Study group | Role | What they receive |
|---|---|---|
| obese patients with type 2 diabetes mellitus | This study is designed as a cross-sectional, descriptive research project. Participants will include patients presenting to the internal medicine outpatient clinic who have a diagnosis of Type 2 diabetes mellitus (T2DM) for a duration of 5 years or longer and a body mass index (BMI) greater than 30 kg/m². Given that hyperglycemia and the metabolic/microvascular consequences of diabetes can have a cumulative effect on muscle mass and quality over time, a duration of >5 years since the T2DM diagnosis is proposed as a screening/risk criterion for sarcopenia. Patients who meet the inclusion criteria and consent to participate will be referred to the Department of Physical Medicine and Rehabilitation for assessment of muscle strength, gait speed, and sarcopenia risk. Handgrip strength, the 5-times-sit-to-stand test, and the 4-meter walk test will be conducted by a physiatrist (specialist in Physical Medicine and Rehabilitation) and a physiotherapist, following a standardized protocol.

What is being measured
The primary outcome is the main question the study is designed to answer.
risk of sarcopenia
SARC-F survey. Scale Title: Strength, Assistance with walking, Rise from a chair, Climb stairs, and Falls (SARC-F) Questionnaire.
Score Range: 0-10 points.
Interpretation: Higher scores indicate a higher risk of sarcopenia and greater severity of sarcopenia-related symptoms and functional limitations. A total score of 4 or higher indicates a positive screening result for sarcopenia risk.
Measured: through study completion, an average of 1 year
Secondary outcomes (3)
muscle strength
Hand grip strength Hand grip strength will be assessed using a hand dynamometer. Grip strength will be measured in kilograms (kg). Higher values indicate greater muscle strength, whereas lower values indicate reduced muscle strength and may be associated with an increased risk of sarcopenia.
Measured: through study completion, an average of 1 year
lower-extremity strength, functional capacity, and fall risk
Five-times sit-to-stand test Description: The Five-Times Sit-to-Stand Test (5xSTS) will be used to assess lower extremity muscle strength and functional performance. Participants will be instructed to stand up from a seated position and sit down five consecutive times as quickly as possible, with their arms crossed over their chest, without using their arms for support. The time required to complete all five repetitions will be recorded in seconds.
Interpretation: Shorter completion times indicate better lower extremity muscle strength and functional performance, whereas longer completion times indicate poorer functional performance and may be associated with an increased risk of sarcopenia.
Measured: through study completion, an average of 1 year
general health status, physical condition
The 4-meter walk test Description: The 4-Meter Walk Test (4MWT) will be used to assess usual gait speed as an indicator of physical performance. Participants will be instructed to walk a 4-meter distance at their usual comfortable walking speed. The time required to complete the distance will be recorded in seconds, and gait speed will be calculated in meters per second (m/s) by dividing the distance walked by the completion time.
Interpretation: Higher gait speed values indicate better physical performance, whereas lower gait speed values indicate poorer physical performance and may be associated with an increased risk of sarcopenia.
Measured: through study completion, an average of 1 year
