Recent concerns over the impact of antidepressant medications, including the selective serotonin reuptake inhibitors (SSRIs), on cardiovascular function highlight the importance of research on the moderating effects of specific lifestyle factors such as physical activity. Studies in affective neuroscience have demonstrated robust acute effects of SSRIs, yet the impact of ...

Stress alters brain cell properties and then disturbs cognitive processes, such as learning and memory. In this study, we investigated the effect of postnatal treadmill exercise on hippocampal neurogenesis and spatial learning ability of rat pups following prenatal noise stress. The impact of exercise intensity (mild-intensity exercise vs heavy-intensity exercise) ...

PURPOSE: Exercise training might exert its beneficial effects on myocardial perfusion by inducing coronary vascular adaptations or enhancing collateralization. We evaluated whether long-term exercise-based cardiac rehabilitation started early after ST-elevation acute myocardial infarction (STEMI) improves myocardial perfusion and left ventricular (LV) function. METHODS: Forty-six patients with recent STEMI and residual ...

Some form of exercise is helpful to achieve target heart rate (THR) in patients undergoing dobutamine Technetium-99 Sestamibi (Cardiolite(®)) stress tests. The outcomes of low-level exercise (slow treadmill walking) and isometric exercises to achieve THR during dobutamine Cardiolite(®) stress tests have not been examined. The purpose of this study was ...

Evolution favored individuals with superior cognitive and physical abilities under conditions of limited food sources, and brain function can therefore be optimized by intermittent dietary energy restriction (ER) and exercise. Such energetic challenges engage adaptive cellular stress-response signaling pathways in neurons involving neurotrophic factors, protein chaperones, DNA-repair proteins, autophagy, and ...

Exercise increases resistance against stress-related disorders such as anxiety and depression. Similarly, the perception of control is a powerful predictor of neurochemical and behavioral responses to stress, but whether the experience of choosing to exercise, and exerting control over that exercise, is a critical factor in producing exercise-induced stress resistance ...

Exercise affects neuroplasticity and neurotransmission including dopamine (DA), which modulates drug-taking behavior. Previous research in rodents has shown that exercise may attenuate the rewarding effects of drugs of abuse. The present study examined the effects of high and low exercise on cocaine responses in male Wistar rats that had been ...

Abstract The glucocorticoid hormones corticosterone (CORT) and cortisol influence numerous physiological, morphological, and behavioral functions. However, few studies have addressed possible relationships between individual differences in glucocorticoid concentrations and whole-animal performance or metabolism. Because CORT is important in glucose regulation and energy metabolism and can influence activity levels, we hypothesized ...

Resistance exercise (RE) stimulates growth hormone (GH) secretion in a load-dependent manner, with heavier loads producing larger GH responses. However, new research demonstrates that low-load RE performed with blood flow restriction (BFR) produces potent GH responses that are similar to or exceed those produced following high-load RE. We hypothesized that ...

The growth hormone/insulin like growth factor-I (GH/IGF-I) system occupies a well-known hormonal role and its effects, mainly anabolic and insulin-sensitizing, are mediated through endocrine as well as paracrine/autocrine mechanisms. This system includes the binding proteins, namely growth hormone binding proteins and Insulin-like growth factor I binding proteins (IGFBPs). As expected, ...

Although systemic hypoxia increases the muscle hyperaemic response during 'steady-state' exercise, its effect on dynamic characteristics of this response is not clear. In the present study we first established that hypoxia increases the steady-state hyperaemic response at low workloads during calf exercise. To study dynamic aspects of this response, eight ...

Moderate exercise enhances fish growth, although underlying physiological mechanisms are not fully known. Here we performed a proteomic and metabolic study in white (WM) and red (RM) muscle of gilthead sea bream juveniles swimming at 1.5 body lengths per second. Continuous swimming for four weeks enhanced fish growth without increasing ...

The number of adult stem cells (ASCs) is very small, limiting the regenerative potential of tissues. One of the most studied ASCs in humans is the satellite cell (SC), which proliferates and increases pool size under exercise stress and muscle damage. This review examines the growth factor response to specific ...

The optimal timing of exercise stress testing post primary percutaneous coronary intervention is uncertain with anecdotal evidence suggesting an increased risk of acute myocardial infarction and/or death if performed too early. This has translated into a delayed return to normal life activities following an acute myocardial infarction resulting in an ...

It is often recommended that heavier training intensities (∼70%-80% of maximal strength) be lifted to maximize muscle growth. However, we have reported that intensities as low as 30% of maximum strength, when lifted to volitional fatigue, are equally effective at stimulating muscle protein synthesis rates during resistance exercise recovery. This ...

We investigated the effects of swimming and treadmill exercise on the level of nerve growth factor (NGF) protein and neurogenesis in the hippocampus, and cognitive function of adult rats over a period of 8 weeks. We divided 144 male Sprague-Dawley rats into 3 groups: (1) a control group (COG; total ...

The addition of aerobic exercise (AE) to a resistance exercise (RE) program (concurrent exercise; CE) can interfere with maximum muscle fiber growth achieved with RE. Further, CE appears to markedly affects the growth of myosin heavy chain (MHC) I, but not MHC IIa fibers. The mechanism responsible for this 'interference' ...

Although human cardiomyocytes (CMs) are capable of some cell division, this response is neither sufficient to repair damaged cardiac tissue nor efficient to compensate for pathological stress. Danio rerio (zebrafish) CMs have been shown to have high proliferative capability to completely repair hearts after injury; however, no reports have focused ...

Modest energy restriction combined with resistance training (RT) has been shown in non-lactating women to protect bone during periods of weight loss. However, there is a paucity of research on dietary interventions and exercise in lactating women aimed at promotion of bone health and weight loss. PURPOSE: To investigate the ...

To clarify the structure of the muscle hyperaemic response during submaximal exercise in the supine position, we tested the hypotheses that this response measured in human calf muscle is biphasic or triphasic (growth-only) at low-moderate or high forces, respectively. Ten subjects performed four series of 5-min bout of intermittent contractions ...

Psychosocial factors, such as chronic mental stress and mood, are recognized as an important predictor of longevity and wellbeing. In particular, depression is independently associated with cardiovascular disease and all-cause mortality, and is often comorbid with chronic diseases that can worsen their associated health outcomes. Regular exercise is thought to ...
