Considerations for clients with chronic disease

General principles for training clients with cardiovascular, metabolic, pulmonary and other chronic conditions — clearance, monitoring, medication effects and safe progression.

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

Learning objectives

  • Explain the evidence for exercise as therapy in chronic disease
  • Apply clearance, monitoring and communication with clinicians
  • Recognise medication effects on exercise responses
  • Adapt intensity and progression for common conditions

Before this lesson

Why this matters

Many clients live with one or more chronic conditions. Exercise is an effective therapy across many diseases [pedersen2015], but responses and risks differ, and medications change how the body reacts.

Fundamental principles

  1. Screen and obtain clearance when indicated [riebe2015].
  2. Communicate with the client’s clinicians — ask for restrictions and targets.
  3. Start lower, progress slower than for healthy clients.
  4. Monitor symptoms, RPE, and condition-specific markers (BP, glucose, oxygen saturation where relevant).
  5. Document every session.

Common conditions — key considerations

ConditionKey considerations
HypertensionCheck resting BP; avoid breath-holding; see hypertension
Type 2 diabetesGlucose before/after if on insulin or sulfonylureas; carry fast carbohydrate; foot care
Coronary artery diseaseClinician-defined intensity ceiling; know warning symptoms
COPD / asthmaBreathlessness scales; inhalers available; intervals often better tolerated
OsteoarthritisLow-impact options; pain-monitoring approach
Cancer survivorsFatigue variability; treatment side effects; clearance

Medications that alter responses

ACSM summarises common effects [acsm2021]: beta-blockers lower HR (use RPE); insulin and some oral agents risk hypoglycaemia; diuretics affect hydration and electrolytes; vasodilators can cause post-exercise hypotension (longer cool-down).

Common mistakes and misconceptions

Case study

A 62-year-old with type 2 diabetes on insulin starts training. The trainer agrees targets with the diabetes team, checks glucose before sessions (delaying exercise if below the agreed threshold), keeps glucose tablets available, and schedules sessions 1–2 hours after meals. HbA1c improves over six months alongside medication adjustments by the doctor.

Short-answer & application questions

  1. List medications that change exercise responses and how you would adapt.
  2. Write a communication note to a client’s physician before starting training.
  3. Describe a symptom-monitoring checklist for each session.

Key takeaways

  • Exercise has therapeutic benefits in many chronic diseases, but must be individualised.
  • Medical clearance, clear clinician communication and symptom monitoring are essential.
  • Medications (beta-blockers, insulin, diuretics, etc.) alter heart rate, glucose and fluid responses.
  • Start lower, progress slower, and use RPE alongside other measures.
