The purpose of study was to explore the effect of CRF training on RSP in older adults.
The study utilized a pilot quasi-experimental design to evaluate pulmonary function tests (PFT) and strength function tests (SFT) at pre- and post-intervention points after twelve weeks with 25 participants aged 60 years and above. An individualized cardio-respiratory fitness (CRF) training protocol, aligned with ACSM guidelines, was conducted three times a week and consisted of a warm-up, conditioning (aerobic, resistance, and balance training), and a cool-down. Aerobic exercises commenced at light intensity (30-39% HRR) for 10-15 minutes and progressed to moderate intensity (40-59% HRR) for 15-20 minutes; resistance training started at light intensity (40-50% of 1 RM) and increased to moderate (51-70%); balance training included progressively challenging movements with gradually reduced support. The cool-down phase focused on flexibility, incorporating active static stretches held for 30-60 seconds.
Significant increases in both FVC and FEV1 were observed from baseline to weeks 8 and 12, indicating improvements in lung capacity and function, while no significant changes were detected in the FEV1/FVC ratio over the study period. Notable enhancements in senior fitness tests were observed, including chair stands, arm curls, flexibility, and agility, particularly in the "8 ft Up and Go" test; the "2 min Step" test exhibited significant improvement only by week 12. Correlation analyses using Pearson’s Correlation Coefficient indicated weak to moderate relationships between lung function and senior fitness measures.
The 12-week CRF training program significantly enhanced pulmonary function, strength, flexibility, and balance in older adults with RSP.
The 12-week CRF training program significantly benefits adults over 60 with restrictive spirometry patterns by enhancing lung capacity (FVC), lung function, strength, flexibility, and dynamic balance. These improvements are vital for supporting daily activities and reducing fall risk, aiding older adults in maintaining independence. Thus, integrating cardiorespiratory fitness training into clinical practice is a practical approach to promoting physical health and extending functional longevity in this population.
