Association between respiratory capacity, quality of life and cognitive function in elderly individuals

OBJECTIVE

To investigate associations between respiratory capacity, quality of life and cognitive function in elderly individuals.

METHODS

The sample included 386 elderly individuals (232 women). Respiratory capacity assessment was based on maximal expiratory pressure measured at peak expiratory flow. Subjects were classified according to peak expiratory flow values adjusted for sex, age and height of individuals with normal (peak expiratory flow curve <80% and >60%) or reduced (peak expiratory flow curve < 60%) respiratory capacity. The World Health Organization Quality of Life Questionnaire and the Mini-Mental State Examination were used to assess quality of life and cognitive function, respectively.

RESULTS

Elderly women with reduced respiratory capacity scored lower on the Mini-Mental State Examination (p=0.048) and quality of life questionnaire (p=0.040) compared to those with normal respiratory capacity. These differences were not observed in men (p>0.05).

CONCLUSION

Reduced respiratory capacity was associated with poorer quality of life and cognitive function in elderly women. These associations were not observed in elderly men.

Short-term respiratory exercise effects, different environments, pulmonary functional and physical capacity in elderly

Abstract Introduction: Aging is often associated with reduced functional capacity (FC) and respiratory muscle strength (RMS). Objective: To verify the short-term aquatic and land-based respiratory exercise effects on RMS, pulmonary function, FC and palmar grip strength (PGS) in healthy elderly women. Methods: A blinded, randomized, controlled clinical trial was conducted. The sample was composed by 32 elderly women, randomized in two groups: Land-Based Group (LG), and Hydrotherapy Group (HG). Exercise program was performed in two weekly sessions (40 minutes each), during four weeks. Evaluations (anthropometry, manovacuometry and spirometry) were performed; FC by the 6-minute Walk Test (6MWT), and PGS test. All evaluations were performed before and after four-week intervention. Results: About RMS evaluation, there was an improvement in the Maximum Expiratory Pressure (MEP) values from 63.8 ± 19 to 74 ± 20 (p = 0.007) of HG. LG had an increase in forced expiratory flow (FEF) between 25-75% of forced vital capacity (FEF 25-75%) from 82 ± 29 to 101 ± 26 (p = 0.04). There was no statistically significant PGS improvement and walking 6MWT distance in both groups. HG presented lower values of Initial Heart Rate and Diastolic Blood Pressure, both pre (p = 0.006) and post 6MWT (p = 0.041). Conclusion: It may be suggested that, in the short-term, the respiratory exercise aquatic protocol has positive effects on the MEP and cardiovascular parameters in elderly.

The Role of Physical Activity on Mood State and Functional Skills of Elderly Women

Introduction:

Ageing is associated with several physical, psychological and behavioral changes. These changes are closely related with global health and functional capacity in the elderly. Mood disturbances are common among the elderly and may significantly increase apathy, resulting in decreased habitual physical activity levels.

Materials and Methods:

The purpose of this cross-sectional study was to evaluate the mood state and functional motor capacities of elderly women engaged in a public physical activity program in Brazil and compare them with physically inactive elderly. Thirty elderly women were included in the study and categorized into two groups: physically active group, composed of participants enrolled on a public physical activity program (n = 16, 69±5 years) and physically inactive group (n = 14, 68±4 years). Total mood disturbance was assessed using the Profile of Mood States, whereas functional motor capacity was evaluated with the Sitting and Rising test. Independent t test and Mann-Whitney U] were used to compare groups.

Results:

The physically active group had lower total mood disturbance (p=0.02), confusion (p<0.01), tension (p<0.01), hostility (p=0.05) and fatigue (p=0.01) compared to the physically inactive group. There were no group differences regarding vigor, depression and sitting and rising performance (p>0.05).

Conclusion:

Lack of difference in functional motor capacity between the physically active and inactive elderly may be explained by the absence of exercise systematization in these programs.
