The plasma triglyceride post-fed state has been mentioned as a predictor for the formation of the atherosclerotic process with possible progression to cardiovascular disease. In contrast, exercise has become an important strategy for reducing levels of circulating triglycerides by promoting increase of lipoprotein lipase activity. Analyzes the eff ects of light combined physical exercise in metabolic variables in elderly physically active post-prandial women. Twenty elderly women (mean 68.02 ± 9.06 years) who had attend of Active Health Programme / Rio Claro-SP, Brazil per one year, often twice a week. The study was divided into two days and in the fi rst day were collected anthropometric measurements, inquiry dietary and level of habitual activity. The second day consisted of a protocol of light physical activity divided into three parts, stretching, aerobic exercise and resistance exercise. Blood samples were collected before and after workout. A signifi cant reduction in blood glucose due to the combined exercise was observed, but no diff erence in triglycerides concentration before and after workout was found. We conclude that light combined physical exercise can promote reduced serum glucose and maintain the triglycerides concentration in physically active elderly in the fed condition.

Young (60 days), pregnant (P) or non-pregnant (NP) rats were fed during pregnancy or for 21 days (the NP) a normal (17%) or a low (6%) protein diet. Serum glucose and insulin levels and pancreas insulin content in the fed state; total area under serum glucose curve (AG) after a glucose load and serum glucose disappearance rate (Kitt) after insulin administration; as well as 86Rb outflow, 45Ca uptake and insulin secretion by isolated pancreatic islets in response to glucose were evaluated. Serum glucose was lower in 17%-P (12%) and 6%-P (27%) than in corresponding NP-rats. Serum insulin was higher in 17%-P (153%) and 6%-P (77%) compared to the corresponding NP-rats. Pancreatic insulin was higher in 6%-rats (55%) than in 17%-rats. No differences were found in AG among the groups whereas Kitt was lower in 6%-NP and higher in 6...

Male Wistar rats were allocated into the following groups: sedentary control, trained control, sedentary diabetic, trained diabetic. Diabetes was induced by alloxan (32 mg/kg, b.w. iv). The physical training protocol consisted of 1 h swimming session/day, 5 days/week for 8 weeks supporting a load corresponding to 90% of maximal lactate steady state. After the experimental period, blood was collected to measure serum glucose, insulin, triglycerides, albumin, insulin-like growth factors-I (IGF-I), and growth hormone (GH). Pituitary gland was removed for GH quantification. Diabetes increased blood glucose and triglycerides and decreased insulin, IGF-I, serum and pituitary GH. Physical training decreased glucose and triglycerides, and also counteracted the reduction of serum IGF-I in diabetic rats. In conclusion, physical training recovered...

Participaram do estudo 15 mulheres e 12 homens (23 ± 2,3 anos) não-atletas, agrupados segundo o nível de aptidão cardiorrespiratória determinado através de teste de campo progressivo e exaustivo. As concentrações de TG e CT foram avaliadas duas horas após o almoço em duas diferentes condições: a) sem exercício e b) com execução de um exercício exaustivo previamente ao almoço -ambas realizadas com uma semana de intervalo. Anova two way para medidas repetidas não revelou diferenças para as concentrações de TG e CT, a despeito do exercício físico. O nível de aptidão cardiorrespiratória associado a uma sessão de exercício físico exaustivo de curta duração não promoveu alterações na lipemia pós-prandial.. Palavras-chave: Atividade Física.

The aim of the present study was to analyze glucose homeostasis and blood lactate during an exercise swimming test in rats treated with alloxan during the neonatal period and/or fed a high calorie diet from weaning onwards. Rats were injected with alloxan (200 mg/kg, i.p.) or vehicle (citrate buffer) at 6 days of age. After weaning, rats were divided into four groups and fed either a balanced diet or a high-caloric diet as follows: C, control group (vehicle + normal diet); A, alloxan-treated rats fed the normal diet; H, vehicle-treated rats fed the high-caloric diet; and HA, alloxan-treated rats fed the high-caloric diet. Fasting serum glucose levels were higher in groups A and AH compared with the control group. The Homeostatic Model Assessment index varied in the groups as follows: H>A>HA = C. There were no differences in free fatty aci...

Half of the animals were submitted to swimming exercise training (trained), 1 h/day, 5 days/week during 8 weeks, with an overload equivalent to the AT. The other half was kept sedentary (sedentary). At the end of the experimental period, the rats were submitted to an oral glucose tolerance test and to another LMT. Then, the animals were sacrificed at rest or immediately after 20 minutes of swimming exercise at the AT intensity for pancreatic islets isolation. At the end of the experiment mean workload (% bw) at AT was higher and blood lactate concentration (mmol/L) was lower in the trained than in the control group. Rats trained at the AT intensity showed no alteration in the areas under blood glucose and insulin during ...

Osteotomy was performed on the upper third of the right tibia of rats. Physical training consisted of swimming 1 h per d with a load of 5% body weight and therapy with medium-intensity ultrasound was applied for 5 min daily. Young adult male Wistar rats were divided into four groups: (1) osteotomized sedentary animals with no ultrasound treatment (OSnUS); (2) trained with no ultrasound treatment (OTnUS); (3) sedentary with ultrasound treatment (OSwUS); and (4) trained with ultrasound treatment (OTwUS). The animals were sacrificed for the following analyses: muscle glycogen and serum alkaline phosphatase on the 5 th , 10 th , 20 th and 30 th days and histological slices of the bone on the 5 th and 20 th days. The results show that ultrasound is better in the initial phases of the process of bone tissue repair and physical exercise at the end of bone consolidation. These facts suggest that the treatments herein used prove favorable to the bone regenerative process, as the overall ossification process has been accelerated.

Some studies show the importance of physical exercise to prevent and minimize various neurological disorders. It is believed that the positive effects of exercise on brain functions are mediated by brain insulin and insulin-like growth factor-1 (IGF-1) signaling. In this study, we investigate the role of swimming exercise training on hippocampus proteins related to insulin/IGF-1 signaling pathway in Type 1 diabetic rats and its effects on spatial memory. Wistar rats were divided into four groups namely sedentary control, trained control, sedentary diabetic (SD), and trained diabetic (TD). Diabetes was induced by Alloxan (ALX) (32 mg/kg b.w.). The training program consisted in swimming 5 days/ week, 1 h/day, per 6 weeks, supporting an overload corresponding to 90% of the anaerobic threshold. We employed ALX-induced diabetic rats to explore learning and memory abilities using Morris water maze test. At the end of the training period, the rats were sacrificed 48 h after their last exercise bout when blood samples were collected for serum glucose, insulin, and IGF-1 determinations. Hippocampus was extracted to determinate protein expression (IR, IGF-1R, and APP) and phosphorylation (AKT-1, AKT-2, Tau, and b-amyloide proteins) by Western Blot analysis. All dependent variables were analyzed by two-way analysis of variance with significance level of 5%. Diabetes resulted in hyperglycemia and hypoinsulinemia in both SD and TD groups (P < 0.05); however, in the training-induced group, there was a reduction in blood glucose in TD. The average frequency in finding the platform decreased in SD rats; however, exercise training improved this parameter in TD rats. Aerobic exercise decreased Tau phosphorylation and APP expression, and increased some proteins related to insulin/IGF-1 pathway in hippocampus of diabetic rats. Thus, these molecular adaptations from exercise training might contribute to improved spatial learning and memory in diabetic organisms. V C 2014 Wiley Periodicals, Inc.
