Abstract
Background: The strength of the respiratory muscles can be evaluated from static measurements of maximal mouth inspiratory pressure and maximal mouth expiratory pressure. Although these data could be suitable for a number of clinical and research applications, no previous studies had provided the impact of respiratory muscles strength on quality of life among elderly for such tests using a healthy, randomly selected sample of the Egyptian elderly. Objectives: to establish the impact of respiratory muscles strength on quality of life for a randomized sample of elderly Egyptian. Methods: 500 subjects were selected from different elderly senior citizen homes and clubs; 213 man and 287 woman .Their age ranged between of 60 and 80 years, with normal body mass index (20-25) Kg/m2. All subjects were strongly urged to make maximum inspiratory (Mueller maneuver) and expiratory (Valsalva maneuver) efforts through the respiratory pressure meter device and the maximum values of three from seven repetitions that vary by less than 20% was recorded and answer the short form 36 questionnaire. The results: there were no significant correlation between respiratory muscles strength and QOL but men showed statistically significantly higher mean scores of (Role limitations due to physical health), (Role limitations due to emotional problems), (Emotional wellbeing) as well as (General health) than women. There was no statistically significant difference between scores of (Physical functioning), (Energy/fatigue), (Social functioning) as well as (Pain) in men and women
