American Health Journal 4-Minute Interview With Richard Casaburi
In this video interview, Richard Casaburi, PhD, MD, and President of PERF, explains the basics of COPD, therapies available, and especially the importance of rehabilitation in the treatment of COPD. “Exercise doesn’t improve the lungs,” he says, “but it improves everything around them so that the patient is able to do more and feel better.” Dana Jones, a COPD patient, also talks on camera about the beneficial effects of rehabilitation on his own life as he copes with his COPD. “I have tremendous function loss in my lungs,” he says, “but exercise helps my body use oxygen better.”
A Study of Leg Training and Breathing Patterns in COPD Patients
In an article co-authored by PERF board member William Stringer, MD, and published in Lung, the effects of leg training were analyzed in a controlled study of 28 COPD patients and 20 matched control subjects. The group of 28 exercised for 45 minutes a day, 4 days a week for 6 weeks on a stationary bicycle, while the control group did not follow this exercise regimen. During the study, maximal inspiratory and expiratory pressures (MIP and MEP), lung volumes, and two constant-work-rate (CWR) exercise tests (low- and high-intensity) were performed.
American Health Journal 4-Minute Interview With Harry Rossiter
In this video interview, Harry Rossiter, PhD, FACSM, who studies exercise physiology, explains about a study being done to measure the amount of mitochondria in muscles. Mitochondria are the engines that your body uses to propel itself. Dr. Rossiter studies how the mitochondria are increased as a result of an exercise training program.
“There are three pillars to better health,” says Dr. Rossiter, “nutrition, sleep, and physical activity.” People who are very fit, who exercise regularly, have more mitochondria in their muscles, and as a result their bodies perform better. In the case of COPD, an increase in mitochondria helps a patient live a healthier life because the body is functioning more efficiently.
Fatigue and COPD: Staying Active for Healthy Living
Last week, we shared a video featuring an interview with Harry Rossiter, PhD, FACSM, about a study involving mitochondria in muscle tissues and how this relates to the quality of health for COPD patients. In this video, Dr. Rossiter gives a comprehensive presentation to the PEP Pioneers about COPD and exercise. You’ll come away from viewing it with a much better understanding of what exactly is going on inside your body and how your level of exercise has such a significant impact on your well-being, especially if you are coping with COPD.
