Physical Impairments Disrupt the Association Between Physical Activity and Loneliness: A Longitudinal Study.
This study explores the association between physical activity (PA), loneliness and the presence of physical chronic impairments among single older adults. METHODS:: A longitudinal study (N = 575; mean age 76 ± 8 years) was conducted. The association between self-reported weekly minutes of moderate to vigorous PA (MVPA), loneliness and presence of physical impairments was assessed with multilevel analyses at baseline, 3 months and 6 months. RESULTS:: Improvements in MVPA were associated with decreases in loneliness (B = - 0.09; SE = 0.04; p = 0.020): this association became non-significant when including the ...

Clustering of Physical Activity and Sedentary Behavior associated to Risk for Metabolic Syndrome in Older Adults.
This study aimed to investigate the clustering patterns of physical activity (PA), sedentary time (ST), and breaks in sedentary time (BST) and the association between the identified clusters with risk for metabolic syndrome associated with obesity in older adults. Participants included 212 users of community health centers (CHC) in Brazil. A questionnaire about sociodemographic characteristics was used to describe the sample, and PA, ST and BST were evaluated using accelerometers. Waist circumference was measured as an indicator of the risk for metabolic syndrome. A two-step cluster and logistic regression analysis was con...

The Social Context of Sedentary Behaviors and their Relationships with Health in Later Life.
This study examined sedentary behaviors among older adults and explored associations with social context and health measures using cross-sectional data from the National Health and Aging Trends Study (N=1,687). Multivariate models were estimated to explore associations of time in six sedentary behaviors (i.e. television watching, sitting and talking, hobbies, computer use, driving, and resting) with sociodemographic characteristics and level of social engagement, and with health status. Results indicated substantial variability in sedentary behaviors, with television being the most frequent, and resting the least frequent ...

Nutritional and Pharmacological Interventions to Expedite Recovery Following Muscle Damaging Exercise in Older Adults: A Narrative Review of the Literature.
Authors: Clifford T Abstract Exercise-induced muscle damage (EIMD) manifests as muscle soreness, inflammation, and reductions in force generating capacity that can last for several days after exercise. The ability to recover and repair damaged tissues following EIMD is impaired with age, with older adults (≥50 years old) experiencing a slower rate of recovery than their younger counterparts do for the equivalent exercise bout. This narrative review discusses the literature examining the effect of nutritional or pharmacological supplements taken to counter the potentially debilitating effects of EIMD in older adu...

Authors: Boutros GEH, Morais JA, Karelis AD Abstract Physical activity plays an important role for achieving healthy aging by promoting independence and increasing the quality of life. However, current guidelines for physical activity in older adults may be difficult to achieve in an older population. Indeed, there is evidence to suggest that increasing exercise intensity in older adults may be associated with greater reductions in the risk of cardiovascular disease and mortality. Therefore, the idea prescribing high intensity exercise protocols such as high intensity interval training and high intensity resistance...

Use of Physical Activity Questionnaires in People With Dementia: A Scoping Review.
Authors: Farina N, Hughes LJ, Watts A, Lowry RG Abstract Physical activity questionnaires are an important means to assess habitual physical activity. It remains unclear what questionnaires are used and whether they are appropriate for people with dementia who have impaired information recall but are also often largely sedentary. This scoping review aimed to identify and quantify the use of physical activity questionnaires within a dementia population. Eighteen studies met the inclusion criteria for this review. The majority of studies used questionnaires that were validated for use within an older adult population...

The Acute Effects of Mat Pilates on Hemodynamic and Salivary Nitrate Responses After Exercise in Postmenopausal Women.
Authors: Batista JP, Mariano IM, Souza TCF, Costa JG, Giolo JS, Cheik NC, Espindola FS, Everman S, Puga GM Abstract The aim of study was to compare the hemodynamic and salivary responses after Mat Pilates, aerobic, resistance exercise and control. 16 normotensive postmenopausal women performed: PILATES:ten floor exercises; AEROBIC:35 minutes on the treadmill (60 to 70%of heart rate reserve); RESISTANCE: 60% of 1RM; CONTROL:no physical exercise. Blood pressure (BP) and heart rate variability (HRV) were evaluated at rest and 60 minutes after the intervention. Saliva samples were collected at rest, immediately, 30' an...

TV Viewing is Associated With All-Cause Mortality in Older Adults With Hypertension: Findings From a 6-Year Longitudinal Study.
Authors: Lemes ÍR, Sui X, Turi-Lynch BC, Blair SN, Fernandes RA, Codogno JS, Monteiro HL Abstract The purpose of this study was to examine the longitudinal association between TV viewing and all-cause mortality in older adults with hypertension. Sedentary behavior, physical activity, hypertension and other chronic diseases were assessed by face-to-face interviews and confirmed by medical history. Mortality was reported by relatives and confirmed in medical records of the National Health System. The fully- adjusted model showed a direct association between high TV viewing time and all-cause mortality (HR: 1.6...

Effects of Water Immersion on Squat and Split-Squat Kinematics in Older Aged Adults.
This study examined the effect of water immersion on trunk and lower limb kinematics during squat exercises in older aged participants. Twenty-four active older aged adults (71.4 ± 5.4 yrs.) performed squats and split-squats on land and while partially submerged in water. Inertial sensors (100 Hz) were used to record trunk and lower-body kinematics. Water immersion increased the squat depth (squat: P=0.028, d=0.63, split-squat: P=0.005, d=0.83) and reduced the trunk flexion range (squat: P=0.006, d=0.76, split-squat: P
