Before and after intervention periods frailty status, blood pressure, heart rate, and a set of physical performance capabilities and cognitive domains were assessed.

Evidence-based recommendations for resistance and power training to prevent frailty in community-dwellers.

Frailty is a reversible state of reduced resilience to stressful events resulting from a multisystem impairment of the human body. As frailty progresses, people become more vulnerable to numerous adverse events, including falls and fractures, cognitive decline, disability, hospitalization, nursing home placement, and death. As such, substantial health care costs are associated with frailty.

The aim of this study was to examine the relationships between isometric handgrip (HG) strength and isokinetic strength data of the glenohumeral rotator muscles. Twelve (Female = 50%) Brazilian Sitting Volleyball (SV) national team players volunteered. Measures of maximal grip strength were obtained by a HG dynamometer Jamar® and isokinetic measures of peak torque (PT) and total work (TW) during shoulder rotations movements were obtained with a Biodex isokinetic dynamometer at speed of 60°/s and 180°/s.

The importance of objectively measuring functional tests in complement to self-report assessments in patients with knee osteoarthritis.

Background: Osteoarthritis (OA) is a chronic degenerative disease which can result in chronic pain, loss of joint function and consequently decline in quality of life.

Research Question: A variety of instruments that measure the different dimensions of health status in patients with OA are available. However, despite the fact that WOMAC and other questionnaires and scales may provide additional understanding regarding the patient's condition, some studies have reported discrepancies between patients' perceptions and their actual ability to perform the task.

Effects of Combined Resistance and Power Training on Cognitive Function in Older Women: A Randomized Controlled Trial.

The present study compared the effects of traditional resistance training (TRT) and combined power training (PT) and TRT (PTRT) on cognitive parameters and serum brain-derived neurotrophic factor (BDNF) levels in non-demented, well-functioning, community-dwelling older women. Forty-five older women were randomized into one of three experimental groups: TRT, PTRT, and control group (CG). Cognitive tests explored global cognitive function, short-term memory, and dual-task performance.

A Training Program Using an Agility Ladder for Community-Dwelling Older Adults.

Aging impairs physical and cognitive functions and limits daily activities. Agility training can improve or maintain physical functioning in older people. The purpose of this study is to report the physical fitness benefits of a training program for independent community-dwelling older adults using an agility ladder.

Dynamic Resistance Training Improves Cardiac Autonomic Modulation and Oxidative Stress Parameters in Chronic Stroke Survivors: A Randomized Controlled Trial.

Stroke survivors are at substantial risk of recurrent cerebrovascular event or cardiovascular disease. Exercise training offers nonpharmacological treatment for these subjects; however, the execution of the traditional exercise protocols and adherence is constantly pointed out as obstacles. Based on these premises, the present study investigated the impact of an 8-week dynamic resistance training protocol with elastic bands on functional, hemodynamic, and cardiac autonomic modulation, oxidative stress markers, and plasma nitrite concentration in stroke survivors.

Periodized and non-periodized resistance training programs on body composition and physical function of older women.

Background And Purpose: Although combining classical resistance (RT) and power training (PT) might be an efficient strategy to achieve optimal enhancements in body composition and physical function in older adults, the most effective approach to combine these different types of exercise training is still unknown. Periodization, an organizational model that refers to a succession of cycle that will vary in exercise intensity and/or volume to allow for the training stimulus to remain biologically challenging and effective, may represent an interesting approach. Among the different types of periodization, daily undulating periodization (DUP) has attracted considerable attention given its superiority in comparison to nonperiodized (NP) RT programs to elicit neuromuscular improvements in young adults.
