Mood and affect and exercise

Jacob D Meyer, Kelli F Koltyn, Aaron J Stegner, Jee-Seon Kim, Dane B Cook
OBJECTIVE: Brain-derived neurotrophic factor (BDNF) has recently emerged as one potential mechanism with which exercise improves mood in major depressive disorder (MDD). This study examined the relationship between changes in serum total BDNF and mood following acute exercise in MDD. It was hypothesized that acute exercise would increase BDNF in an intensity-dependent manner and that changes in BDNF would be significantly related to improvement in depressed mood post-exercise. METHODS: Twenty-four women (age: 38...

Following binding to cannabinoid receptors, endocannabinoids regulate a variety of central nervous system processes including appetite and mood. Recent evidence suggests that the systemic release of these lipid metabolites can be altered by acute exercise and that their levels also vary across the 24-h sleep-wake cycle. The present study utilized a within-subject design (involving 16 normal-weight men) to determine whether daytime circulating endocannabinoid concentrations differ following three nights of partial sleep deprivation (4...

The study investigated whether typical psychological, physiological, and neurophysiological changes from a single exercise are affected by one's beliefs and expectations. Seventy-six participants were randomly assigned to four groups and saw different multimedia presentations suggesting that the subsequent exercise (moderate 30 min cycling) would result in more or less health benefits (induced expectations). Additionally, we assessed habitual expectations reflecting previous experience and beliefs regarding exercise benefits...

Millions of levothyroxine-treated hypothyroid patients complain of impaired cognition despite normal TSH serum levels. This could reflect abnormalities in the type 2 deiodinase (D2)-mediated T4-to-T3 conversion, given their much greater dependence on the D2 pathway for T3 production. T3 normally reaches the brain directly from the circulation or is produced locally by D2 in astrocytes. Here we report that mice with astrocyte-specific Dio2 inactivation (Astro-D2KO) have normal serum T3 but exhibit anxiety-depression-like behavior as found in open field and elevated plus maze studies and when tested for depression using the tail-suspension and the forced-swimming tests...

BACKGROUND: Previous research has shown that gratitude positively influences psychological wellbeing and physical health. Grateful people are reported to feel more optimistic and happy, to better mitigate aversive experiences, and to have stronger interpersonal bonds. Gratitude interventions have been shown to result in improved sleep, more frequent exercise and stronger cardiovascular and immune systems. These findings call for the development of technologies that would inspire gratitude...

OBJECTIVE: To examine the relation between daily diary reports of diabetes-specific social interactions to patient and partner mood and patient self-care behaviors, and whether relations are moderated by unmitigated communion. METHOD: Participants were 70 couples in which 1 person had been diagnosed with Type 2 diabetes in the past 3 years. They were interviewed in-person at baseline and completed daily diary reports on an iPad. Daily diary questionnaires measured support, mood, and self-care behavior (patients only)...

The inflammatory bowel disease (IBD) consisting of Crohn's disease (CD) and ulcerative colitis (UC) are defined as idiopathic, chronic and relapsing intestinal disorders occurring in genetically predisposed individuals exposed to environmental risk factors such as diet and microbiome changes. Since conventional drug therapy is expensive and not fully efficient, there is a need for alternative remedies that can improve the outcome in patients suffering from IBD. Whether exercise, which has been proposed as adjunct therapy in IBD, can be beneficial in patients with IBD remains an intriguing question...

An association between mood disturbance, the inability to lose or to stop gaining weight, and a craving for carbohydrates is manifested by many people who are overweight or are becoming so. In a recent study, we observed that low-calorie weight loss diet lowered not only levels of leptin but also levels of essential amino acid tryptophan (TRP) significantly. The disturbed metabolism of TRP might affect biosynthesis of serotonin and could thereby increase the susceptibility for mood disturbances and carbohydrate craving, increasing the cessation probability of weight reduction programs...

Mood homeostasis present sexually dimorphic traits which may explain sex differences in the incidence of mood disorders. We explored whether diverse behavioral-setting components of mood may be differentially regulated in males and females by exercise, a known modulator of mood. We found that exercise decreases anxiety only in males. Conversely, exercise enhanced resilience to stress and physical arousal, two other important components of mood, only in females. Because exercise increases brain input of circulating insulin-like growth factor I (IGF-I), a potent modulator of mood, we explored whether sex-specific actions of exercise on mood homeostasis relate to changes in brain IGF-I input...

Across 3 experiments, we rely on theoretical advancements that connect movement, embodiment, and reward-seeking behavior to test the proposal that walking incidental to routine activity (heretofore referred to as "incidental ambulation")-not specifically "exercise"-is a robust facilitator of positive affect. Experiment 1 reveals that ambulation facilitates positive affect even when participants are blind to the purpose of this activity. Experiment 2 further demonstrates the robustness of this effect of incidental ambulation by documenting its operation under conditions of low interest, as well as its power to override expectations of mood worsening...

UNLABELLED: Stress urinary incontinence (SUI) has an independent will, uncontrolled leakage of urine from the bladder during exercise, sneezing, coughing, laughing, bending or lifting heavy objects. It leads to an increase in abdominal pressure, resulting in a failure of muscular-ligamentous. This problem affects both women and men. Can lead to serious mental disorders such as depression, low self-esteem and dignity, decline in social status, deterioration of mood, anxiety and a decrease in sexual activity...

Neurocognitive deficits are common with brain tumors. If assessed at presentation using detailed neurocognitive tests, problems are detected in 80 % of cases. Neurocognition may be affected by the tumor, its treatment, associated medication, mood, fatigue, and insomnia. Interpretation of neurocognitive problems should be considered in the context of these factors. Early post-operative neurocognitive rehabilitation for brain tumor patients will produce rehabilitation outcomes (e.g., quality of life, improved physical function, subjective neurocognition) equivalent to stroke, multiple sclerosis, and head injury, but the effect size and duration of benefit needs further research...

Although colloquial wisdom and some studies suggest an association between regular aerobic exercise and emotional well-being, the nature of this link remains poorly understood. We hypothesised that aerobic exercise may change the way people respond to their emotions. Specifically, we tested whether individuals experiencing difficulties with emotion regulation would benefit from a previous session of exercise and show swifter recovery than their counterparts who did not exercise. Participants (N = 80) completed measures of emotion response tendencies, mood, and anxiety, and were randomly assigned to either stretch or jog for 30 minutes...

UNLABELLED: Fibromyalgia is a chronic pain syndrome that is associated with maladaptive plasticity in neural central circuits. One of the neural circuits that are involved in pain in fibromyalgia is the primary motor cortex. We tested a combination intervention that aimed to modulate the motor system: transcranial direct current stimulation (tDCS) of the primary motor cortex (M1) and aerobic exercise (AE). In this phase II, sham-controlled randomized clinical trial, 45 subjects were assigned to 1 of 3 groups: tDCS + AE, AE only, and tDCS only...

BACKGROUND/OBJECTIVE: Very low-carbohydrate, high-fat (LC) diets are used for type 2 diabetes (T2DM) management, but their effects on psychological health remain largely unknown. This study examined the long-term effects of an LC diet on psychological health. METHODS: One hundred and fifteen obese adults [age: 58.5 ± 7.1 years; body mass index: 34.6 ± 4.3 kg m(-2) ; HbA1c : 7.3 ± 1.1%] with T2DM were randomized to consume either an energy-restricted (~6 to 7 MJ), planned isocaloric LC or high-carbohydrate, low-fat (HC) diet, combined with a supervised exercise programme (3 days week(-1) ) for 1 year...

This group study explored how an intervention of diet and lifestyle, including a vegan diet, fruit and vegetable juicing, nutritional supplements, regular exercise, and destressing techniques, would affect 27 subjects with anxiety, depression, poor memory, dementia, Alzheimer's disease, Parkinson's disease, history of stroke, or multiple sclerosis. Several subjects had overlapping conditions. Videotaped testimonials were obtained describing subjective results. Testimonials stated multiple benefits across all conditions addressed by the study, with subjects often reporting substantial benefits...

Pain during delivery is unique because it is accompanied by powerful emotions. Emotions that occur in women during labor and delivery are closely tied to upbringing and culture in which they were raised and consequently with the sensation of experienced pain. According to the Melzack-Wall Theory of Pain, general mood is directly related to the intensity and quality of pain and it is therefore justifiable to presuppose that certain psychosocial factors will be linked with the intensity and quality of pain experienced during childbirth...

Long-duration exercise has been linked with the psychological model of flow. It is expected that the flow experience is characterized by specific changes in cortical activity, especially a transient hypofrontality, which has recently been connected with an increase in cognitive performance post-exercise. Nevertheless, data on neuro-affective and neuro-cognitive effects during prolonged exercise are rare. The cognitive performance, mental state, flow experience, and brain cortical activity of 11 ultramarathon runners (6 female, 5 male) were assessed before, several times during, and after a 6-h run...
