Improving Function of Patients with COPD

1. Improving Function of Patients with COPD Sarah Demarest, Rachel Flaherty, Ali Hafele, & Beth Niebuhr Bellarmine University

2. PICO Question • Aerobic interval exercise compared to strength training http://thenutrifarm.com/can-you-stop-the-progression-of-copd/

3. COPD & Exercise Characteristics • Limited • Exercise capacity • Ventilatory constraints (http://www.livingwellwithcopd.com/en/what-is-copd.html)

4. COPD Training A) Dyspnea B) Leg Fatigue C) Lactate Concentration Interval Continuous (Kortianou, 2013)

5. COPD Training • Oxygen Uptake (VO2) • Minute Ventilation (VE) Interval Continuous (Kortianou, 2013)

6. Benefits of Interval Training Peripheral Muscle Ventilatory Tolerate high intensity exercise Limited increase of lactate Prolonged tolerance to ventilation Lower perception of dyspnea • Increases ms oxidative capacity • Increases cross sectional area of Type I and IIa fibers • Decreases Type IIb fibers • Limited increase of lactate • (Information provided by: Vogiatzis, 2002; Kortianou, 2013)

7. 12 Week Exercise Program for Patients with COPD Initial sessions Freq: 3-4x/wk Mode: 20-30s on/30-40s off Intensity: 80% max work load Duration: 15-20mins Increasing Intensity 5-10% of peak capacity Use 10-point Borg scale - Legs 5-6 - Dyspnea 3-4 • Increasing Time • - 30-90 mins (including rest) (Information provided by: Vogiatzis, 2002; Kortianou, 2013)

8. Benefits of Interval Training  Interval° Continuous 5 9 13 17 21 25 Training Session (Information provided by: Vogiatzis, 2002; Kortianou, 2013)

9. Clinical Implications: Interval vs. Continuous Indications: • work related training • improve domestic function • less dyspnea with ADL’s (Vogiatzis, 2002) (Voiatzis, 2002)

10. Strength Training For COPD Pts • Reasons to Strength Train • Muscle atrophy • Dyspnea • Low tolerance levels • De-conditioned • Resistance training is preferred if peripheral muscle atrophy is the main limiting factor over cardiovascular issues (Information provided by Ortega, 2002; Spruit, 2002)

11. Strength Training Results • Increased: • FEV1 • Power for cycle ergometry • QOL • Peripheral muscle force • Muscle endurance • Muscle strength (Clark, 2000) (Information provided by: Spruit, 2002; Wright, 2003)

12. Benefits of Strength Training • Improved pulmonary function • Improved endurance capacity • Improved general well-being (Information provided by: Wright, 2003, Clark, 2000)

13. Strength Training in Patients with Mild COPD 12 week Training Program: • Patients with mild COPD • 2x/week • Cycling/walking warm-up and cool-down • 3x10 reps of 8 individual weight exercises: • bench press (triceps) • body squat (quadriceps) • squat calf (medial and lateral gastroc; soleus) • latissimus (latissimus dorsi) • arm curls (biceps) • leg press (quadriceps, hamstrings, gluteals) • knee flexion (quadriceps) • hamstrings (Clark, 2000)

14. (Kaelin, 2001)

15. Conclusion Patients with COPD have decreased strength and endurance capacity Resistance training can allow for strength and endurance gains Patients are better able to tolerate interval training compared to continuous The optimal exercise treatment program for patients with COPD is a combination of resistance training and interval training for improving function.
