OBJECTIVE: Immune challenges result in sickness responses such as decreased activity, fever, and spatial learning deficits. While these responses occur simultaneously, they are not usually evaluated concurrently or for an extended time. The purpose of this study was to examine how an immune challenge affected activity and temperature responses in animals tested concurrently in the Morris water maze (MWM) over 5 days and how aging interacts with such responses. METHOD: An accepted model of aging, adult ( n = 10; 5-6 months) and aged ( n = 7; 22 months) male Brown-Norway rats were implanted with a telemetry device (Mini Mitter, Oakmont, PA) to continuously monitor temperature and activity following an immune challenge...

BACKGROUND: Peripheral arterial disease (PAD) is a common cardiovascular pathology affecting mobility in elderly. Osteoarticular diseases (ODs), responsible for functional limitations and confounding leg symptoms, may interfere with exercise therapy. This study evaluates the feasibility and effectiveness of a structured home-based exercise programme on rehabilitative outcomes in a cohort of elderly PAD patients with and without coexisting ODs. PATIENTS AND METHODS: Patients were enrolled from 2002 to 2016 in an exercise programme prescribed and controlled at the hospital and based on two daily 10-minute home walking sessions below the self-selected speed...

Isometric handgrip (IHG) training is effective in reducing blood pressure (BP), but little is known about the occurrence of acute hypotension by post-isometric exercise hypotension (PIEH) and the underlying mechanisms. Ten sedentary hypertensive elderly people (seven women and three men) individuals, with a mean age of 73.2±2.2 years and systolic BP (SBP) of 135.1±6.5, were included; they were hypertensive for 13.2±6.9 years and were receiving medications. These patients underwent two experimental sessions of isometric exercise using a portable hydraulic handgrip dynamometer: (i) sham session with 3% of maximal voluntary isometric contraction (MVIC) and (ii) experimental isometric session with 30% MVIC, completing a total of 8 sets of 1 min contraction and 1 min rest pause (overload of work = 51...

Chronic diseases-including cancer, cardiovascular diseases, and metabolic conditions such as diabetes and obesity-account for over 60% of overall global mortality. Sedentary time increases the risk for chronic disease incidence and mortality, while moderate to vigorous physical activity is known to decrease risk. Most Americans spend at least half of their time sedentary, with a trend toward increasingly sedentary lifestyles, and few Americans achieve recommended levels of physical activity. Time spent outdoors has been associated with reduced sedentary time and increased physical activity among children/youth and the elderly, but few population-based studies have examined this relationship among working age adults who may face greater constraints on active, outdoor time...

Background: Aging causes physiological changes which affect the quality of sleep. Supervised physical exercise is an important therapeutic resource to improve the sleep of the elderlies, however there is a low adherence to those type of programs, so it is necessary to implement an exercise program which is feasible and effective. The study aimed to test the hypothesis that a semi-supervised home exercise program, improves sleep quality and daytime sleepiness of elderlies of the community who present poor sleep quality...

PURPOSE: Physical inactivity behavior at middle age or older is a major risk factor for cardiovascular disease. However, the effects of levels of habitual physical activity on arterial stiffness in elderly population remain unclear currently. Therefore, the purpose of this study was to demonstrate whether the effects of habitual physical activity could attenuate arterial stiffness in elderly individuals via a meta-analysis. METHODS: We searched the Medline and Embase databases from January 1997 through November 2017, using the medical subject headings "older population", "physical activity" (e...

BACKGROUND: Essential hypertension (EP) is characterized by blood pressure (BP) elevations, which often lead to target organ damage and cardiovascular illness. The following study investigates whether aerobic exercise programs with different intensities could reduce the magnitude of BP rise. METHODS: Patients with essential hypertension were recruited from the Baoshan Community Health Service Center. A total of 46 patients were finally selected and randomly assigned into two groups: control group (CON) included patients who did not participate in exercise intervention training; treatment group (TRG) included patients who participated in 12-week brisk walking training (60-min of brisk walking, three times a week for a total of 12 weeks)...

BACKGROUND: Cardiovascular diseases (CVD) are the leading cause of mortality. In 2014, they were responsible for 38.9% of all causes of death in Germany. One major risk factor for CVD is a lack of physical activity (PA). A health-promoting lifestyle including regular PA and minimizing sitting time (ST) in daily life is a central preventive measure. Previous studies have shown that PA decreases in older age; 2.4-29% of the people aged over 60 years achieve the World Health Organization recommendations...

BACKGROUND: Aging-related loss of muscle and strength with increased adiposity is prevalent among older people in long-term care (LTC) facilities. Studies have shown that people with sarcopenic obesity (SO) are at high risk of declining physical performance. At present, no interventional studies on residents with SO in nursing homes have been conducted in the literature. The objectives of this study include appraising the changes in body composition and physical performance following resistance training among residents with SO in LTC facilities...

Surgery in combination with risk factors such as poor physical and nutritional status have detrimental effects on short- and long-term aspects of recovery and quality of life, especially in elderly patients whose functional reserve is limited. Strategies to minimize these effects and accelerate return to baseline levels have focused on the intra- and post-operative period; however, this may not be the most opportune time to intervene. Instead, the preoperative period may be a more emotionally salient and physically enabling time to initiate an intervention aimed at attenuating surgical stress and enhancing recovery after surgery...

Despite increasing longevity, many old people are not in good health. There has been an increase in the prevalence of age-associated multi-morbidity (two or more chronic conditions in the same person). Also, severe infections, such as pneumonia, remain significant causes of mortality and morbidity in this aging group. Many chronic health conditions share risk factors such as increasing age, smoking, a sedentary life style and being part of a lower socioeconomic group. However, despite this, multi-morbidities often co-occur more commonly than would be predicted...

BACKGROUND: Higher levels of physical activity and cardiorespiratory fitness are positively related to serum 25-hydroxyvitamin D [25(OH)D] concentrations; however, the response of 25(OH)D concentrations to chronic endurance exercise training is unclear. Therefore, the purpose of this study was to elucidate whether serum 25(OH)D concentrations were directly increased by 5 weeks of endurance exercise training and influenced by changes in body fat in elderly men. METHODS: Twenty elderly Japanese men were randomized to either the 5-week endurance exercise training group (ET group; N = 10) or the sedentary control group (SC group; N = 10)...

Accurate monitoring of sedentary behaviour and physical activity is key to investigate their exact role in healthy ageing. To date, accelerometers using cut-off point models are most preferred for this, however, machine learning seems a highly promising future alternative. Hence, the current study compared between cut-off point and machine learning algorithms, for optimal quantification of sedentary behaviour and physical activity intensities in the elderly. Thus, in a heterogeneous sample of forty participants (aged ≥60 years, 50% female) energy expenditure during laboratory-based activities (ranging from sedentary behaviour through to moderate-to-vigorous physical activity) was estimated by indirect calorimetry, whilst wearing triaxial thigh-mounted accelerometers...

INTRODUCTION: Sarcopenic obesity (SO) is a term that refers to an increase of fat mass together with a decrease of muscle mass, which is suffered by a high percentage of elderly population. Physical activity seems to be a good strategy to prevent it getting worse. However, genetic factors related to the aging process and to elderly's physical fitness could have an influence on it. AIM: To determine if elderly women > 60 who practice physical activity regularly had differences in sarcopenic obesity according to the I/D polymorphism from the ACE (angiotensin converter enzyme) gen...

The 'classical' distribution of type 2 diabetes (T2D) across the globe is rapidly changing and it is no longer predominantly a disease of middle-aged/elderly adults of western countries, but it is becoming more common through Asia and the Middle East, as well as increasingly found in younger individuals. This global altered incidence of T2D is most likely associated with the spread of western diets and sedentary lifestyles, although there is still much debate as to whether the increased incidence rates are due to an overconsumption of fats, sugars or more generally high-calorie foods...
