Julia C Basso, Joan I Morrell
BACKGROUND: Though voluntary wheel running (VWR) has been used extensively to induce changes in both behavior and biology, little attention has been given to the way in which different variables influence VWR. This lack of understanding has led to an inability to utilize this behavior to its full potential, possibly blunting its effects on the endpoints of interest. NEW METHOD: We tested how running experience, sex, gonadal hormones, and wheel apparatus influence VWR in a range of wheel access "doses"...

Metabolic stress is a physiological process that occurs during exercise in response to low energy that leads to metabolite accumulation [lactate, phosphate inorganic (Pi) and ions of hydrogen (H(+))] in muscle cells. Traditional exercise protocol (i.e., Resistance training) has an important impact on the increase of metabolite accumulation, which influences hormonal release, hypoxia, reactive oxygen species (ROS) production and cell swelling. Changes in acute exercise routines, such as intensity, volume and rest between sets, are determinants for the magnitude of metabolic stress, furthermore, different types of training, such as low-intensity resistance training plus blood flow restriction and high intensity interval training, could be used to maximize metabolic stress during exercise...

The present study determined changes in appetite-regulating hormones and energy intake after high-intensity interval exercise (HIIT) under hypoxic conditions in trained female athletes. Fifteen female athletes completed three trials on different days of either HIIT under hypoxic conditions (HYP), HIIT under normoxic conditions (NOR), or rest in normoxia (CON). Exercise trials consisted of two successive sets of eight repeated bouts of a 6-s maximal sprint separated by a 30-s rest. Blood samples were obtained to measure plasma acylated ghrelin, glucagon-like peptide-1 (GLP-1), and metabolite concentrations...

Sarcopenia is defined as low muscle function (walking speed or grip strength) in the presence of low muscle mass. A simple screening test - the SARC-F - is available to identify persons with sarcopenia. The major endocrine causes of sarcopenia are diabetes mellitus and male hypogonadism. Other causes are decreased physical activity, loss of motor neuron units, weight loss, inflammatory cytokines, reduced blood flow to muscles, very low 25(OH) vitamin D levels and decreased growth hormone and IGF-1. Treatment for sarcopenia includes resistance and aerobic exercise, leucine enriched essential amino acids, and vitamin D...

Decreased anabolism because of alterations in the insulin-like growth factor 1 (IGF-1)/growth hormone (GH) axis and increased catabolism induced by proinflammatory cytokines like tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) have been reported to contribute to muscle wasting in chronic heart failure (CHF). However, it is unclear whether exercise training could modulate anabolic and catabolic markers in CHF patients. The purpose of this study was to investigate the effects of exercise intervention on anabolic and catabolic markers for patients with CHF...

The number of childhood cancer survivors is increasing as survival rates improve. However, complications after treatment have not received much attention, particularly metabolic syndrome. Metabolic syndrome comprises central obesity, dyslipidemia, hypertension, and insulin resistance, and cancer survivors have higher risks of cardiovascular events compared with the general population. The mechanism by which cancer treatment induces metabolic syndrome is unclear. However, its pathophysiology can be categorized based on the cancer treatment type administered...

High-intensity exercise suppresses appetite partly through changes in peripheral appetite-regulating hormones. Lactate and interleukin-6 (IL-6) mediate the release of these hormones in animal/cell models and may provide a mechanistic link between exercise intensity and appetite regulation. The current study examined changes in appetite-regulating hormones, lactate, and IL-6 after different intensities of running. Eight males completed four experimental sessions: 1) Moderate-intensity continuous training (MICT; 65% VO2max); 2) Vigorous-intensity continuous training (VICT; 85% VO2max); 3) Sprint interval training (SIT; repeated "all-out" sprints); 4) Control (CTRL; no exercise)...

Excessive positive energy balance is a major factor leading to obesity. The ability to alter the appetite-regulating hormones leptin, adiponectin, and ghrelin may help decrease excessive energy intake. Exercise and exposure to extreme temperatures can independently affect these appetite-regulating hormones. PURPOSE: To determine the effect of exercising in different environmental conditions on the circulating concentrations of leptin, adiponectin, and ghrelin. METHODS: Eleven recreationally-trained male participants completed 3 separate 1 h cycling bouts at 60% Wmax in hot, cold, and room temperature conditions (33°C, 7°C, 20°C), followed by a 3 h recovery at room temperature...

Type 1 diabetes mellitus (T1DM) is characterized by the loss of insulin secreting cells due to a directed autoimmune process, which is linked to oxidative stress and inflammation. Exercise training is known to induce several benefits by reducing inflammation and improving antioxidant defenses. In this context, exercise training may be considered as an efficient and relatively inexpensive non-pharmacological tool for diabetes treatment, added to the usual insulin administration. Unfortunately, most people with T1DM do not reach the recommended levels of physical activity due to concerns with hypoglycemic episodes...
