RESUMO

Lower extremity muscle strength (LEMS) and body balance (BB) are essential for older adults to maintain an upright posture and autonomously perform their basic activities of daily living. This study aimed to examine whether LEMS and BB mediate the relationship between physical activity (PA) and health-related quality of life (HRQoL) in a large sample of community-dwelling older adults. This is a cross-sectional study carried out with 802 individuals, 401 males and 401 females (69.8 ± 5.6 years), residents of the Autonomous Region of Madeira, Portugal. PA and HRQoL were assessed by the Baecke Questionnaire and e SF-36, respectively. LEMS was assessed by the Senior Fitness Test and BB by the Fullerton Advance Balance (FAB). The serial mediation pathway model pointed out that LEMS and BB partially mediated the association between PA and HRQoL in approximately 39.6% and 47%, respectively. The total variance in HRQoL explained by the entire model was 98%. Our findings may indicate the role that LEMS and BB play in the relationship between PA and HRQoL in the older population.

RESUMO

BACKGROUND: Physical activity (PA) level is decreased in individuals with Parkinson´s disease (PD). To increase the PA level improves both motor and non-motor symptoms of this population. It is known that gait performance and five times sit-to-stand (FTSTS) are associated with PA level; therefore, it is of great relevance for rehabilitation purposes to understand whether these variables may predict PA level of individuals with PD. OBJECTIVE: To investigate whether gait performance and FTSTS are predictors of PA level. METHODS: Cross-sectional study with individuals with idiopathic PD modified Hoehn and Yahr staging scale between 1.0 and 3.0. The gait performance was measured by Functional Gait Assessment (FGA) and PA level was measured by an accelerometer for one week, during day and night through their time spend in locomotion (locomotion time-LT). Multiple linear regression was conducted with gait performance and FTSTS as independent variables and PA level (LT) as dependent variable. RESULTS: Twenty-two participants were included, mean age 64.82 (8.39) and the mean storage of accelerometer time was 9.866 min (0.33). Both gait performance and FTSTS have moderate significant correlation with PA level (r = - 0.538 p < 0.01 and r = 0.625 p < 0.001, respectively). The linear regression model with FGA and FTSTS was significant (p < 0.05) and predicted 41% of LT. CONCLUSION: Gait performance and FTSTS have important interaction with PA level measured by LT in individuals with PD, and it provides insights on the importance of these variables in predicting the PA level of its population.

RESUMO

Background: Older females have less dynamic postural control and muscle strength than do middle-aged females. Aging-related strength losses may limit balancing performance. Objective: The purpose of this study was to investigate the ability of the Y Balance Test (YBT) and lower limb strength to discriminate between females in 2 age groups, the relationship between YBT distance and the Berg Balance Scale (BBS), and the degree to which performance on YBT distance is related to lower limb strength in middle-aged and older females. Method: The 40 healthy, independently active females were divided into 2 groups: older and middle-aged. The participants underwent measurements of YBT distance using the YBT, maximal muscular strength of the lower limbs using a handheld dynamometer, and the BBS. Results: The YBT distance in 3 directions and lower limb muscle strength for both lower limbs were significantly lower in the older adults than in the middle-aged group. A moderate correlation but insignificant correlation was found between the YBT composite distance and the BBS score. In the older females, YBT distance was significantly positively correlated with strength of the knee flexor and hip abductor. In the middle-aged group, YBT distance was significantly positively correlated with strength of the knee flexor and hip extensor. Conclusions: Performance on the YBT was influenced by the strength of lower limb. We suggested that YBT can be used to alternative as a measurement of dynamic balance. Proper training programs for older people could include not only strengthening exercises but also YBT performance to improve balance. .
