Inclusion criteria
Inclusion criteria: ? Adult women aged 61 to 90 ? Women who have not engaged in regular exercise within the past 3 months ? Women capable of performing moderate exercise ? Women with sarcopenia or at risk according to AWGS criteria ? Women who have completed the informed consent form ? Women who can participate in the study for 12 weeks
Exclusion criteria
Exclusion criteria: ? Individuals with a history of major cardiovascular or cerebrovascular events within the previous 6 months, including myocardial infarction, worsening angina, stroke, or severe heart failure, or those presenting with high-risk symptoms such as chest pain or syncope during exercise stress testing. ? Individuals with uncontrolled hypertension (resting systolic blood pressure =180 mmHg or diastolic blood pressure =110 mmHg) or severe cardiovascular conditions, including clinically significant arrhythmias, that may increase the risk associated with participation in the intervention. ? Individuals with severe musculoskeletal disorders (e.g., recent fractures or surgery, severe osteoarthritis, chronic low back pain, or lower-extremity pain) that would hinder participation in step or treadmill exercise. ? Individuals with neurological disorders (e.g., Parkinson’s disease or gait impairment resulting from brain lesions) that markedly compromise balance and walking ability. ? Individuals with severe respiratory diseases or severe anemia that limit the ability to perform exercise. ? Individuals who are pregnant, likely to become pregnant during the study period, or in the postpartum recovery period (according to institutional criteria), as well as those taking medications or having medical conditions that may substantially influence muscle mass or metabolism, such as long-term systemic corticosteroid use, active cancer treatment, or uncontrolled thyroid dysfunction. ? Individuals who have experienced substantial body weight changes within the previous 3 months (unintentional rapid weight loss or gain), which could confound the interpretation of study outcomes.
