Methods	Study design: Unclear how participants were assigned to intervention/control groups Total duration of study: 5 weeks of education followed by 30 days of exercise Details of any run‐in period: None documented Number of study centres and location: Unclear. Voronezh State Medical University, Russia Study setting: Not explicitly stated Withdrawals: Not stated Date of study: Not stated
Participants	Number recruited: Not stated Number completed: 60 (30 intervention group, 30 control group) Mean (SD) age: Intervention group 49.8 (1.11) years. Control group 49.94 (0.95) years Age range: Not stated Gender (M/F): Intervention group 8/22. Control group 7/23 Mean (SD) BMI: Intervention group 32.87 (0.37). Control group not stated Severity of condition: Assessment of asthma severity included the number of exacerbations, calls to emergency service, and hospital admissions in the past 12 months. Diagnostic criteria: Asthma diagnosis based on assessment of symptoms, medical history, health status, and spirometry parameters according to GINA Baseline lung function: Intervention group: mean (SD) FEV1 61.17 (0.84); mean (SD) FVC 65.40 (0.66). Control group: mean (SD) FEV1 59.92 (0.80); mean (SD) FVC 64.69 (2.67) Smoking history: Not stated Asthma treatment: Not stated Inclusion criteria: Aged 18 to 60 years. Diagnosis of asthma. Diagnosis of metabolic syndrome according to International Diabetes Federation (IDF) criteria Exclusion criteria: Not stated
Interventions	Intervention: Standard pharmacologic therapy in addition to exercise and education. Education consisted of 5 x 1.5‐hour group seminars on the management and prevention of asthma and metabolic syndrome. Exercise was conducted daily for 30 days, after the education course. Comparison: Standard pharmacologic therapy Concomitant medications: Standard pharmacologic therapy Excluded medications: Not stated
Outcomes	Primary outcomes: Not explicitly defined Secondary outcomes: Not explicitly defined The following outcomes are reported: asthma severity (exacerbation rate, emergency calls, hospital admissions), asthma symptoms (VAS), asthma control (ACT), spirometry, quality of life (SF‐36), anthropometrics (waist circumference, BMI), blood pressure, metabolic syndrome markers (fasting glucose, glucose tolerance test, lipid profile). Time points reported: Baseline and 12 months
Notes	We contacted study authors to clarify eligibility criteria, but have received no response. It is unclear: (1) how participants were assigned to the intervention or control groups; and (2) what type of physical exercise(s) the participants in the intervention group performed and the dosage of exercise (intensity, number of sessions per week, number of weeks).
