  1. Chapter 12 Resistance-Training Strategies for Individuals with Coronary Heart Disease

  2. Coronary Heart Disease (CHD) • Caused by atherosclerosis • Hardening of arteries • Blood flow reduced through coronary arteries to heart muscle • Typically results in chest pain and/or heart damage

  3. Managing CHD • Resistance-training programs • Cardiovascular exercise • Proper diet • Lifestyle modifications • E.g., stress management, smoking cessation

  4. Prevalence of CHD • Leading cause of death for men and women in US • CHD-related event occurs approximately every 29 seconds • Death related to CHD occurs approximately every minute

  5. Prevalence of CHD • Risk of CHD: • Men = 49 percent • Women over age 40 = 32 percent

  6. Etiology of CHD • Atherosclerosis • Build up of fatty material and plaque in coronary arteries • Narrowed coronary arteries cause flow of blood to heart to slow or stop

  7. Etiology of CHD • Symptoms: • Chest pain • Shortness of breath • Heart attack • Others

  8. Risk Factors for CHD • Family history • Poor diet • Lack of exercise • Excess cholesterol • Smoking • Diabetes

  9. Cardiac Rehabilitation • Comprehensive, long-term program • Includes: • Medical evaluation • Prescribed exercise • Cardiac risk factor modification • Education • Counseling

  10. Cardiac Rehabilitation • Designed to limit physiologic and psychological effects of cardiac illness among other benefits • Incorporates latest research in exercise prescription

  11. Research Supports Resistance Training • Improves mood and muscular strength • Limits: • Angina • ST segment depression • Cardiovascular complications • Pulmonary complications

  12. Research Supports Resistance Training • Increases muscular strength • Alleviating stress related to performing activities of daily living • Improves overall quality of life • Increases bone density • Countering effects of immunosuppressive therapy

  13. Research Supports Resistance Training • Increases lean body mass • May create more favorable blood lipid levels • Increases cardiovascular conditioning • Lowers blood pressure • Enhances insulin uptake

  14. Program Design Considerations • Requires physical and cardiopulmonary exercise test • Test results form basis of exercise program • ACSM has specific guidelines

  15. Exercise Testing Considerations • Can safely use 1 RM assessment on individuals with CHD • Can perform maximal strength testing two to four weeks post-event • RM should fall within 8 to 15 RM range to ensure assessment of strength

  16. Exercise Testing Considerations • Use electrocardiogram (EKG) monitoring during RM testing to detect arrhythmias • Monitor blood pressure during 1 RM assessment for hypertensive clients

  17. Exercise Testing Considerations • Systolic blood pressure should not exceed 30 to 40 mm Hg • Refer to Table 12.2 • Other testing methods available

  18. Program Components • Exercise selection critical • Not all exercises appropriate • Exercises must increase strength and lean body mass • Minimizing adverse effects • Continually emphasize proper performance

  19. Program Components • Exercises should mimic activities of daily living • Refer to Table 12.3 • Major goal of training: • Gain muscular strength • Minimum rest time of two minutes between sets

  20. Program Components • Perform whole-body workouts two to three days per week • Ideally perform resistance training before cardiovascular work • Keep training format the same each time • See sample 24-Week Program
