Randomized Controlled Trial

Some concerns

Aged 50 years or older; willing to comply with study procedures and follow-ups; able to communicate and provide written informed consent.

Fractures or severe arthritis in the past 6 months; chronic kidney disease (stage III and over); contraindications for magnetic resonance imaging (MRI); use of anabolic hormones in the past 3 months; current disability or limited functional ability; advanced, active or uncontrolled diseases, such as poorly controlled diabetes (HbA1c >9.0%), hyperthyroidism or thyroid insufficiency, Cushing’s syndrome, adrenal insufficiency, or others judged by principal investigators; dementia, cognitive impairment or other sensory impairment limiting communication and understanding of the study; milk allergy or lactose intolerance.

This study aimed to examine the effects of Sarcojoint® plus resistance exercise on muscle mass, muscle strength, and physical performance among community-dwelling middle-aged and older persons in a 12-week double-blinded randomized controlled trial.

We used a computer-generated allocation to generate random codes as a simple randomized method and placed them in concealed envelopes. These procedures were performed by an independent researcher who did not participate in participant screening, intervention, or data analysis. Research nurses confirmed that the envelopes remained sealed until the initial assessment was completed, and the participants were kept blinded during the entire process.
