Effects of age on physiological and psychological functioning among COPD patients in an exercise program

Area of Science:

• Gerontology
• Pulmonology
• Rehabilitation Medicine

Background:

• Older adults with chronic illnesses, such as chronic obstructive pulmonary disease (COPD), are at higher risk for psychological distress.
• Age-related differences in physiological and psychological responses to exercise interventions in older adults with COPD are not fully understood.

Purpose of the Study:

• To examine the effect of age on physiological and psychological functioning in older adults with COPD undergoing a rehabilitation program.
• To compare the outcomes of a 30-day exercise, education, and stress management program between younger-old and older-old adults with COPD.

Main Methods:

• Sixty-four older adults with COPD participated in a 30-day multimodal rehabilitation program including exercise, education, and stress management.
• Physiological (e.g., ergometry, 12-minute walk), cognitive (e.g., memory, psychomotor speed, concentration), and psychological (e.g., anxiety, depression) assessments were conducted pre- and post-intervention.
• Data were analyzed using repeated measures multivariate analysis of variance, with age (median split at 67.5 years) as a between-subject factor.

Main Results:

• Both younger-old and older-old participants with COPD demonstrated improvements in physiological functioning and psychological well-being.
• The exercise program showed a potentially greater positive effect on physiological functioning, concentration, and short-term memory in the younger-old group.
• Significant gains in overall psychological well-being were observed across both age groups.

Conclusions:

• A 30-day rehabilitation program involving exercise, education, and stress management is beneficial for both younger and older adults with COPD.
• While younger-old individuals may experience more pronounced cognitive benefits, all participants achieve significant improvements in physical and mental health.
• Age should be considered when tailoring rehabilitation strategies for older adults with COPD to maximize functional and psychological outcomes.
