Stroke disability stems from insufficient neurorepair mechanisms. Improvement of functions has been achieved through rehabilitation or therapeutic agents. Therefore, we combined exercise with a neurovascular protective agent, S-nitrosoglutathione (GSNO), to accelerate functional recovery. Stroke was induced by middle cerebral artery occlusion for 60 min followed by reperfusion in adult male ...

The guideline physical activity levels are prescribed in terms of time, frequency, and intensity (e.g., 30 minutes brisk walking, five days a week or its energy equivalence) and assume that different activities may be combined to meet targeted goals (exchangeability premise). Habitual runners and walkers may quantify exercise in terms ...

Glyceroneogenesis is an important step in the control of fatty acid re-esterification with PEPCK and PDK4 being identified as key enzymes in this process. We have previously shown that glyceroneogenic enzymes such as PDK4 are rapidly induced in white adipose tissue during exercise. Recent studies have suggested that IL-6 regulates ...

Current physical activity recommendations assume that different activities can be exchanged to produce the same weight-control benefits so long as total energy expended remains the same (exchangeability premise). To this end, they recommend calculating energy expenditure as the product of the time spent performing each activity and the activity's metabolic ...

Exercise has been demonstrated to potently protect substantia nigra pars compacta (SN) dopaminergic neurons from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced neurotoxicity. One mechanism proposed to account for this neuroprotection is the upregulation of neurotrophic factors. Several neurotrophic factors, including Brain Derived Neurotrophic Factor (BDNF), have been shown to upregulate in response to exercise. ...

Evidence exists regarding the potential role of exogenous nucleotides as regulators of the immune function in physically active humans, yet the potential use of nucleotides has been hindered by their low bioavailability after oral administration. We conducted a double-blind, placebo-controlled, randomized trial to assess the effect of sublingual nucleotides (50 mg/day) ...

In adipose cells, adipose triglyceride lipase (ATGL) catalyzes the first step in adipocyte triacylglyceride hydrolysis, thereby regulating both basal and hormone-stimulated lipolysis. However, little is known about the molecular mechanism(s) underlying habitual exercise-induced adaptive modulation of ATGL in white adipocytes via alteration in transcription regulator and lipolytic cofactors. Male Wistar ...

Evidence from several studies consistently shows decline in cardiorespiratory (CR) fitness and physical function after disabling stroke. The broader implications of such a decline to general health may be partially understood through negative poststroke physiologic adaptations such as unilateral muscle fiber type shifts, impaired hemodynamic function, and decrements in systemic ...

Speculation exists that a positive affective response experienced during exercise may play an important role in predicting exercise adherence. Previous studies using self-paced exercise protocols have been associated with health benefits and pleasant experiences. However, all of these studies were conducted in laboratories, and consequently, the external validity of the ...

INTRODUCTION: Chronic hemiparetic stroke individuals are at a higher risk of falling. This may be due to balance impairments, cardiovascular deconditioning, and muscle weakness associated with stroke effects. Postural instability associated with fatigue would likely be attained more rapidly for stroke individuals than for healthy individuals. OBJECTIVE: To determine the ...

Expectancy-value models of motivation have been applied to understanding children's choices in areas such as academics and sports. Here, an expectancy-value paradigm is applied to exercising (defined as engaging in physical activity). The notion of perceived cost is highlighted in particular. Two hundred twenty children in third, fourth, and fifth ...

Tendinopathy is a failed healing response of the tendon. Despite an abundance of therapeutic options, very few randomized prospective, placebo-controlled trials have been carried out to assist physicians in choosing the best evidence-based management. Eccentric exercises have been proposed to promote collagen fiber cross-link formation within the tendon, thereby facilitating ...
