Metabolic syndrome training guidelines

Defining metabolic syndrome with harmonised criteria including South Asian waist cut-offs, and prescribing combined exercise, sitting reduction and lifestyle change.

Intermediate Evidence: Strong evidence 3 min read Reviewed 2026-10-31 Status: draft

Learning objectives

  • List the harmonised criteria for metabolic syndrome
  • Apply population-specific waist cut-offs
  • Prescribe combined exercise for metabolic syndrome
  • Integrate sitting reduction, diet and sleep

Before this lesson

Why this matters

Metabolic syndrome substantially raises the risk of cardiovascular disease and type 2 diabetes. It is common among South Asians, often at lower body weights.

Harmonised criteria (3 of 5) [alberti2009]

CriterionThreshold
Waist circumferencePopulation-specific (South Asian commonly ≥90 cm men, ≥80 cm women)
Triglycerides≥150 mg/dL (or treatment)
HDL cholesterol<40 mg/dL men, <50 mg/dL women (or treatment)
Blood pressure≥130 systolic or ≥85 diastolic (or treatment)
Fasting glucose≥100 mg/dL (or treatment)

Prescription

ComponentGuidance
Aerobic150–300 min/week moderate, progressing [garber2011]
Resistance2–3 days/week
SittingBreak up prolonged sitting; high activity offsets sitting risk [ekelund2016]
Sleep7+ hours supports cardiometabolic health [stonge2016]

Common mistakes and misconceptions

Case study

A 42-year-old with a normal BMI but 94 cm waist, high triglycerides and borderline BP adopts walking, strength training and earlier bedtimes. After 6 months, waist and triglycerides fall below thresholds.

Short-answer & application questions

  2. Design a combined programme for metabolic syndrome.
  3. Explain metabolic syndrome to a client.

Key takeaways

  • Metabolic syndrome is diagnosed when 3 of 5 risk factors are present.
  • Waist cut-offs are population-specific; for South Asians commonly ≥90 cm (men) and ≥80 cm (women).
  • Combined aerobic and resistance training improves multiple components.
  • Reducing sitting and improving diet and sleep add further benefit.
