“…To date, studies that have examined changes in HMW adiponectin with acute exercise have primarily been conducted in healthy populations, with only one study completed in obese men (25) or in an animal model (12). Results show that in healthy persons, there is little or no change in plasma adiponectin oligomer concentrations with acute exercise (4,20).…”

“…In addition, we have shown that seven consecutive days of vigorous exercise training is sufficient to induce improvement in insulin sensitivity in type 2 diabetic patients (18). A recent publication using rodents also suggests that high-intensity exercise increases plasma HMW adiponectin more so than low-intensity exercise ( 12). However, whether short-term moderate-or high-intensity exercise can produce a similar effect in obese adults is unknown.…”

ObJEcTIVE: To evaluate the effect of prolonged intensive aerobic exercise and acute energy deficit (180 km ultra-marathon race) on serum leptin, adiponectin, resistin and visfatin levels and their association and interaction with serum cortisol and insulin levels in highly trained ultra-endurance runners. DESIGN: The study included 17 highly trained ultra-endurance male athletes (mean age 51.29±6.84 years and body mass index (ΒΜΙ) 23.51±1.90) participating in the 5 th Olympian Race held in Greece on May 2010. Anthropometric values were assessed; serum cortisol, insulin, leptin, adiponectin, resistin and visfatin levels were measured at baseline, post-exercise and ~20 hours after the end of the race. RESULTS: All hormonal values of the post-exercise and recovery status were corrected for plasma volume changes. The estimated energy deficit during the ultra-endurance event was about 5000 Kcal. At the end of the race serum resistin levels were elevated (p<0.001) and serum leptin levels were reduced (p<0.001) and failed to reach pre-exercise levels, although showing a tendency towards restoration. No significant changes were noted in serum adiponectin and visfatin levels. cONcLUsIONs: Ultra-endurance aerobic exercise and acute negative energy balance lead to an up-regulation of serum resistin levels and a down-regulation of serum leptin levels.

“…Eder (2009) corroborates the results of this study, finding that intermittent training showed an increase in depletion of post-exercise VLDL-TAG and decrease in hepatic deposits of TAG, suggesting higher transport of triacylglyceride to the periphery, seeking to replenish the intramuscular deposits in the post exercise. Garekani et al (2011) points out that the total fat levels in animals with high and moderate levels of exercise are lower compared to sedentary animals, because such alterations also depend on the adaptations the body realizes in the metabolism to meet the energy expenditure during the practice of the exercise.…”

Can the Intermittent Training Generate Alterations on the Liver Tissue of Rats Submitted to a Hyperlipidic Diet?

SUMMARY Studies indicate that increasing physical activity and decreasing levels of fat in the liver help to decrease the risk of morbidity from liver conditions. This study aimed to evaluate the effects of an eight week intermittent training program on the liver tissue of rats subjected to a hyperlipidic diet. The study consisted of 30 male Wistar rats, divided into the following groups: Sedentary Control (SC) Exercise Control (EC) (fed on standard feed and water) Sedentary Obese (SO) and Exercise Obese (EO) (fed on bacon, ham, sausage, biscuits, soda and standard feed), which performed intermittent training through electrically stimulated jumps, with three sets of 12 repetitions, three times per week for eight weeks. At the end of the training period, the animals were euthanized, and their livers removed for histological processing and hematoxylin and eosin staining (HE). Soon afterwards, caryometric analysis of the hepatocyte nuclei was performed. From the presented results it can be seen that the hepatocyte nuclei of the obese animals were smaller in relation to those of the control animals, therefore, exercise combined with an appropriate diet proved to be efficient in not causing alterations in the hepatocyte nuclei, conserving normal cell function and reducing the chances of the appearance of tissue damage. Furthermore, exercise in isolation cannot be considered a protective factor against the alteration of the liver cells.
