Exclusion criteria

Exclusion criteria: Individuals with advanced cardiovascular disease, clinically significant arrhythmias, severe COPD or FEV1 less than 50% predicted, uncontrolled hypertension, or any acute or chronic illness incompatible with the safe implementation of the exercise protocol People with a history of allergy to fish oil or omega-3, continuous use of omega-3 supplements in the last three months, use of smoking cessation medication, and addiction to other tobacco and narcotic substances (except cigarettes in the target groups) were excluded from the study.

Design outcomes

Primary

MeasureTime frame
Interleukin-6 (IL-6). Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: Serum IL-6 levels will be determined using commercially available human ELISA kits (ZellBio, Germany), based on the sandwich enzyme-linked immunosorbent assay (ELISA) method.;C-reactive Protein (CRP). Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: Serum CRP levels will be measured using the CRP US kit (USA). Quantitative determination of high-sensitivity C-reactive protein (hs-CRP) in human serum will be performed by the immunoturbidimetric assay, according to the manufacturer’s instructions.;IL-6/hs-CRP. Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: The IL-6 to hs-CRP ratio is calculated by dividing the serum concentration of IL-6 (expressed in pg/mL) by the serum concentration of hs-CRP (expressed in mg/L).;Clara Cell Protein (CC16). Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: Serum Cla

Secondary

MeasureTime frame
Systolic and Diastolic Blood Pressure (SBP, DBP). Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: Systolic and diastolic blood pressure will be measured from the participant’s right arm using a digital blood pressure monitor, Beurer BM20. Before measurement, participants will rest in a seated position for 25 minutes. Blood pressure will be recorded three times at 5-minute intervals, and the average of the three measurements will be considered the final blood pressure value.;Body composition indices (height, weight, body fat percentage, and BMI). Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: Participants’ height will be measured using a stadiometer, Seca model 769, made in Germany, with an accuracy of 1 millimeter. Body weight will be recorded using a Camoushita body scale with an accuracy of 0.1 kilograms. Body fat percentage will be determined using a caliper, model SH5020.Calculation of Body Mass Index (BMI)Body Mass Index will be calculated using the following formula: BMI (kg/m2) = weight (kg) / height (m2).;24-hour food reminder. Timepoint: Primary outcomes will be assessed at two time points: At baseline (pre-test), 24 hours before the initiation of any exercise training or omega-3 supplementation; After eight weeks of intervention (post-test), 48 hours following the completion of the HIIT program and/or omega-3 supplementation. Method of measurement: During the intervention period, participants in the e
