The purpose of this study was to evaluate the profile of serum iron in spontaneously hypertensive rats after an aerobic physical exercise. To accomplish this, 12 normotensive Wistar rats and 12 spontaneously hypertensive rats were distributed into "physical exercise" and "no physical exercise" groups. The animals in the physical exercise group underwent to an aerobic exercise for a total of 4 weeks. Blood was collected for the analysis of iron. Our results indicate that rats of the physical exercise group had significantly lower serum iron levels after the aerobic exercise protocol compared to the spontaneously hypertensive rats no physical exercise group (F ((3,16)) = 4.4915, p < 0.01). No significant difference was found between no physical exercise groups. The results indicated that the difference in iron may be due to an increased demand for iron, prompted by chronic physical exercise. In addition, erythrocytosis has been associated with increased blood pressure in spontaneously hypertensive rats, suggesting that iron reduction may be related to decreased blood pressure in these animals.

We compared the autonomic and hemodynamic cardiovascular effects of amlodipine and enalapril treatment associated with an aerobic physical training program on spontaneously hypertensive rats.
Phalaris canariensis L. (Pc), known as birdseed is rich in tryptophan. The aqueous extract of Pc (AEPc) treatment reduced systolic blood pressure (SBP) in spontaneously hypertensive rats (SHR) via mec...
Chronological aging in healthy subjects is associated with declines in muscle mass, strength, endurance, and aerobic fitness. Older individuals respond favorably to exercise, suggesting that physical ...
Elevated serum retinol binding protein 4 (RBP4) levels were previously described in insulin-resistance states. Exercise training can improve insulin sensitivity and RBP4, but the time-response effect ...
Urine samples were obtained from a previously completed study that showed lentil consumption attenuates the increase in blood pressure that occurs over time in spontaneously hypertensive rats (SHRs). ...

The aim of this study is to evaluate the effect of muscular exercise on iron metabolism in healthy volunteers. Fourteen healthy male subjects will have to pedal on an ergocycle for 45 minu...
Iron overload is a life-threatening condition that can lead to liver disease, cardiac disease, diabetes and arthritis. Simultaneous supplementation with both iron and AA may place individu...

Several iron compounds are used for fortification, including ferrous sulphate and NaFeEDTA. The absorption profile of these may differ because of differences in their dissolution in the ga...
Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
Anemia characterized by decreased or absent iron stores, low serum iron concentration, low transferrin saturation, and low hemoglobin concentration or hematocrit value. The erythrocytes are hypochromic and microcytic and the iron binding capacity is increased.
Transient reduction in blood pressure levels immediately after exercises that lasts 2-12 hours. The reduction varies but is typically 5-20 mm Hg when compared to pre-exercise levels. It exists both in normotensive and hypertensive individuals and may play a role in excercise related PHYSIOLOGIC ADAPTATION.
Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.
