Multiple causes contribute to the prolonged reaction-times (RT) observed in elderly persons. The involvement of antagonist muscle co-activation remains unclear. Here the Mm. Biceps and Triceps Brachii activation in 64 apparently healthy elderly (80 ± 6 years) and 60 young (26 ± 3 years) subjects were studied during a simple RT-test (moving a finger using(More)
BACKGROUND Fatigue or lack of interest can reduce the feasibility of intensive physical exercise in nursing home residents. Low-volume exercise interventions with similar training effects might be an alternative. The aim of this randomised controlled trial was to investigate the feasibility of Whole Body Vibration (WBV) in institutionalised elderly, and its(More)
BACKGROUND AND AIMS Performance variability of reaction time is regarded as an important parameter for cognitive functioning with aging. We investigated three types of variability, diversity (or variability between persons), dispersion (variability across trials within one task) and inconsistency (variability across testing occasions), while distinguishing(More)
This study evaluated whether reaction times (RT) and performance variability are potential markers for the early detection of Alzheimer's disease (AD). Cognitively healthy elderly (n = 218), persons with amnestic MCI (a-MCI) (n = 29) and patients with AD (n = 50) were examined with RT tasks with increasing complexity, subdividing RT into a decision and a(More)
The purpose of the study was to examine the acute effect of a strength training session on brain-derived neurotrophic factor and insulin-like growth factor 1. Furthermore, the influence of a 10-week strength training program on brain-derived neurotrophic factor (BDNF) and insulin-like growth factor-1 (IGF-1) resting levels and memory performance was(More)
Ageing is associated with a chronic low-grade inflammatory profile (CLIP). Physical exercise could circumvent the deleterious effects of CLIP by influencing circulating inflammatory mediators and neurotrophic growth factors. This study aimed at assessing whether 12 weeks of progressive strength training (PST) influences circulating brain-derived(More)
We have used a multiplex bead array assay to detect simultaneously 25 different circulating cytokines in 35 control subjects (young versus old) and 29 patients (young versus old) with acute infection. Intracellular PBMC levels of heat shock proteins (Hsp) were determined using flow cytometry. Levels of MIG and IL-6 were higher in the elderly normal subjects(More)
PURPOSE To examine the influence of a selective noradrenaline reuptake inhibitor (SNRI) on the exercise-induced increase in circulating brain-derived neurotrophic factor (BDNF). METHODS In a double-blind, placebo-controlled, crossover design, 11 young, healthy male subjects were treated with either placebo or reboxetine. On each occasion, they performed a(More)
BACKGROUND Heat shock proteins (Hsp) are ubiquitously synthesised in virtually all species and it is hypothesised that they might have beneficial health effects. Recent studies have identified circulating Hsp as an important mediator in inflammation - the effects of low-grade inflammation in the aging process are overwhelming. While much is known about(More)
BACKGROUND Age-related losses of muscle mass, strength, and function (sarcopenia) pose significant threats to physical performance, independence, and quality of life. Nutritional supplementation could positively influence aspects of sarcopenia and thereby prevent mobility disability. OBJECTIVE To test the hypothesis that a specific oral nutritional(More)
