Inclusion criteria
Inclusion criteria: Healthy young adults aged between 18 and 50 years; Absence of previous diagnosis of chronic diseases, such as diabetes mellitus (type 1 or type 2), hypertension, cardiovascular diseases, neuromuscular or metabolic disorders; No use of continuous medications, including antihypertensives, antidiabetics, anti-inflammatory drugs, beta-blockers, or any other medication that may influence metabolism, the cardiovascular system, or muscle function; No use of supplements or ergogenic substances (e.g., creatine, caffeine, beta-alanine) in the 30 days prior to participation in the study; Absence of musculoskeletal injuries, chronic pain, orthopedic conditions, or any other physical limitation that prevents prolonged sitting (minimum of 3 hours); Consent to follow all research protocol guidelines, with availability to participate in the experimental session and complete all study stages
Exclusion criteria
Exclusion criteria: Interruption or non-completion of any phase of the study, including initial screening, anthropometric assessments, reference tests, or the experimental session; Development of any acute condition (e.g., fever, infection, acute injury) or diagnosis of a chronic condition during the screening and data collection period that may interfere with the study outcomes; Intake of alcohol, caffeine, medications, or ergogenic supplements within the 24 hours prior to the experimental session; Participants with elevated levels of sedentary behavior (e.g., more than 12 hours/day sitting) or engaging in vigorous physical activity (>300 minutes/week) that may influence the study results; Exposure to environmental conditions that may alter thermoregulation or cardiovascular function (e.g., sunburn, hot baths close to the experimental session)
