Abstract
Purpose: This study aimed to evaluate whether supplementation with L-arginine alone or in combination with physical exercise training can modulate rats' lipid and inflammatory profiles after a single intense exercise session. Methods: Male Wistar rats were divided into four different groups: control (C), trained (T), supplemented with L-arginine (C + A) and trained and supplemented (T + A). Animals from supplemented groups (C + A and T + A groups) received 300 mg/kg animal body weight L-arginine diluted in 30 mL of drinking water for 8 weeks. Exercise training protocol (moderate intensity-70% achieved in the maximum effort test) was held 5 days/week for 8 weeks. Results: Exercise training induced a decrease in the amount of plasma, cholesterol and triglyceride totals, and skeletal muscle VEGF and CINC. Supplementation alone showed a benefit by reducing LDL levels. Conclusion: Training combined with supplementation showed a pronounced reduction in skeletal muscle VEGF and CINC amount. L-arginine supplementation, especially when associated with the regular aerobic physical exercise at moderate intensity was able to improve not only plasma lipid profile but also the inflammatory response of skeletal muscle immediately after an exhaustive physical exercise session.

Abstract
Background During a session of prolonged and exhaustive exercise, such as a marathon race, large quantities of free radicals are produced and can oxidise (ox) several molecules, such as low-density lipoprotein (LDL). To prevent oxidative damage, athletes present higher antioxidant levels. However, the effect of marathon running on the natural IgM or IgG anti-oxLDL autoantibodies is not understood. Thus, we investigated the effect of a marathon race on oxidative stress and the mechanisms of control of this stress. Methods Blood samples of 20 marathon runners were collected 24 hours before, immediately and 72 hours after a marathon race to evaluate: plasma lipid profile; serum levels of oxLDL and anti-oxLDL autoantibodies (IgM and IgG isotype) and total antioxidant capacity (TAC). Maximum oxygen uptake (VO2max) was also determined. Results Immediately after the race, oxLDL and TAC levels decreased in comparison to the basal levels; however, the IgM or IgG anti-oxLDL levels remain unchanged. Whereas no differences were observed in the IgM or IgG anti-oxLDL levels 72h after the marathon, the oxLDL and TAC levels returned to the basal values. Significant positive correlations were observed between oxLDL and LDL-cholesterol before, and 72h after the marathon. Significant negative correlations were observed between oxLDL and VO2max immediately after the marathon and 72 h later, as well as between oxLDL and TAC 72 h after the race. Conclusions Athletes with a higher VO2max and total antioxidant activity presented reduced LDL oxidation. The levels of IgM or IgG anti-oxLDL autoantibodies were not affected by running the marathon.

Abstract
Although exercise increases HDL-cholesterol, exercise-induced changes in HDL metabolism have been little explored. Lipid transfer to HDL is essential for HDL's role in reverse cholesterol transport. We investigated the effects of acute exhaustive exercise on lipid transfer to HDL. We compared plasma lipid, apolipoprotein and cytokine levels and in vitro transfer of four lipids from a radioactively labeled lipid donor nanoemulsion to HDL in sedentary individuals (n = 28) and in marathon runners (n = 14) at baseline, immediately after and 72 h after a marathon. While HDL-cholesterol concentrations and apo A1 levels were higher in marathon runners, LDL-cholesterol, apo B and triacylglycerol levels were similar in both groups. Transfers of non-esterified cholesterol [6.8 (5.7-7.2) vs. 5.2 (4.5-6), p = 0.001], phospholipids [21.7 (20.4-22.2) vs. 8.2 (7.7-8.9), p = 0.0001] and triacylglycerol [3.7 (3.1-4) vs. 1.3 (0.8-1.7), p = 0.0001] were higher in marathon runners, but esterified-cholesterol transfer was similar. Immediately after the marathon, LDL- and HDL-cholesterol concentrations and apo A1 levels were unchanged, but apo B and triacylglycerol levels increased. Lipid transfer of non-esterified cholesterol [6.8 (5.7-7.2) vs. 5.8 (4.9-6.6), p = 0.0001], phospholipids [21.7 (20.4-22.2) vs. 19.1 (18.6-19.3), p = 0.0001], esterified-cholesterol [3.2 (2.2-3.8) vs. 2.3 (2-2.9), p = 0.02] and triacylglycerol [3.7 (3.1-4) vs. 2.6 (2.1-2.8), p = 0.0001] to HDL were all reduced immediately after the marathon but returned to baseline 72 h later. Running a marathon increased IL-6 and TNF-α levels, but after 72 h these values returned to baseline. Lipid transfer, except esterified-cholesterol transfer, was higher in marathon runners than in sedentary individuals, but the marathon itself acutely inhibited lipid transfer. In light of these novel observations, further study is required to clarify how these metabolic changes can influence HDL composition and anti-atherogenic function.

Abstract
The objective of this study was to determine the effect of a marathon run on serum lipid and lipoprotein concentrations and serum muscle enzyme activities and follow their recovery after the run. These blood concentrations were measured before, immediately after, and serially after a marathon run in 15 male recreational runners. The triglyceride level was significantly elevated postrace, then fell 30% below baseline 1 day after the run, and returned to baseline after 1 week. Total cholesterol responded less dramatically but with a similar pattern. High-density lipoprotein cholesterol remained significantly elevated and low-density lipoprotein cholesterol was transiently reduced for 3 days after the run. The total cholesterol/high-density cholesterol ratio was significantly lowered for 3 days. Serum lactate dehydrogenase activity significantly doubled postrace and then declined but remained elevated for 2 weeks. Serum creatine kinase activity peaked 24 hr after the run, with a 15-fold rise, and returned to baseline after 1 week. The rise of these enzymes reflects mechanically damaged muscle cells leaking contents into the interstitial fluid. It is concluded that a prolonged strenuous exercise bout in recreational runners, such as a marathon, produces beneficial changes in lipid blood profiles that are significant for only 3 days. However, muscle damage is also evident for 1 week or more from the dramatic and long-lasting effect on enzyme levels. Laboratory values for these runners were outside normal ranges for some days after the race.

Abstract
Proposed mechanisms for the cardioprotective benefits of exercise include decreased lipid deposition and increased reverse cholesterol transport (RCT). RCT involves the efflux of tissue free cholesterol into high-density lipoprotein (HDL) particles, esterification by lecithin:cholesterol acyltransferase (LCAT), transfer to other lipoproteins by cholesterol ester transfer proteins (CETP), and liver excretion. We tested the hypothesis that RCT is enhanced in athletes and that this can occur without large increases in plasma HDL cholesterol (HDL-C) mass levels. Fasting venous blood was drawn from 13 sedentary men and 11 athletes exercising at the rate of 5,185 +/- 501 kcal/wk. Compared with controls, athletes had similar age, body mass index (BMI), HDL-C (P > .1) and apolipoprotein (apo) A-1 (P > .5) levels, and lower low-density lipoprotein cholesterol (LDL-C) (P < .05) and apo B (P < .03) levels. The net mass of free cholesterol transported (NMCT) out of cultured human fibroblasts into the athletes' serum was greater than that for controls (25.5 +/- 8.0 v 7.1 +/- 2.6 micrograms/mL/h, P = .048). The efflux component of this transport correlated with HDL-C and apo A-1 levels and was similar between groups (P = .24), suggesting that athletes' antiatherogenic NMCT findings were due to decreased cholesterol influx into the cells. Athletes had increased plasma LCAT (20.3 +/- 2.1 v 13.9 +/- 1.5 micrograms/mL/h, P = .028) and CETP activities (69.7 +/- 4.5 v 21.5 +/- 4.8%/mL/h, P < .001). The NMCT positively correlated with CETP and LCAT activities and inversely with apo B levels and the cardiac risk ratio apo B/A-1.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The acute effects of low-intensity exercise on plasma lipids were assessed in 22 healthy, normolipidaemic volunteers [mean age (SEM) 21.1 (0.2) years] of whom 11 were untrained and 11 endurance trained. Each subject walked for 2 h on a treadmill at a speed selected to elicit 30% [29.8 (3.9)%] of his or her maximal oxygen uptake. All subjects consumed a similar diet, i.e. 48% of energy from carbohydrate, for 2 days prior to the test. Pre-exercise, high-density lipoprotein (HDL) cholesterol concentration was higher in the trained group than in the untrained group [0.88 (0.06) mmol.l-1 vs 0.73 (0.09) mmol.l-1, P less than 0.05]. The walk elicited an increase in blood lactate concentration (P less than 0.01) but glucose homeostasis was well maintained by both groups. After 2 h of walking total cholesterol had increased by 13 (0.6)% (P less than 0.05). HDL cholesterol concentration increased by 17 (1.6)%, so that the ratio of total to HDL cholesterol was lower after the walk than pre-exercise (P less than 0.05). In the endurance-trained group HDL cholesterol concentration increased progressively, being 7.9 (2.4)% higher after 1 h and 19.7 (1.6)% higher after 2 h. A different response was evident in the untrained group where a rise after the 1st h [25.1 (2.3)%] was followed by a decrease towards pre-exercise values. These results show that one prolonged bout of low-intensity exercise modifies lipoprotein metabolism and hold out the interesting possibility that this response may differ in trained and untrained individuals.

Abstract
The effect of clomipramine on plasma lipoproteins, including high density lipoprotein (HDL) subfractions in five healthy males was investigated. The concentrations of total plasma cholesterol and low density lipoprotein cholesterol decreased slightly while that of total HDL-cholesterol showed a small increase, giving a decrease (p less than 0.05) in the ratio of total plasma cholesterol to HDL-cholesterol. The level of HDL2-cholesterol increased (p less than 0.01) with clomipramine treatment while there was no significant change in the concentration of HDL3-cholesterol. Gradient gel electrophoresis showed that administration of the drug was associated with an increase in the relative concentration of HDL2a as well as of HDL2b and a decrease in that of HDL3b/3c. The plasma concentration of apolipoprotein (Apo) A-I showed a small but insignificant increase. These changes in lipoprotein profile are characteristic of those associated with a decrease in coronary risk.

Abstract
The effect of diet on exercise-induced changes in the plasma concentrations of lipoproteins was examined in six healthy male subjects during walks of 37 km on each of four successive days. With a high-carbohydrate diet (85% of the calories as carbohydrate) there was an increase (P less than .05) in the concentration of very-low-density lipoprotein (VLDL)-cholesterol and VLDL-triglyceride and a decrease (P less than .01) in the concentration of high density lipoprotein (HDL)-cholesterol, due mainly to a decrease in HDL3-cholesterol (P less than .01), and HDL-protein (P less than .001). In contrast, a high-fat diet (75% fat) produced a decrease (P less than .01) in the concentration of VLDL-cholesterol and VLDL-triglyceride with increases (P less than .01) in HDL-protein concentration and in HDL-cholesterol concentrations that arose largely from an increase (P less than .001) in HDL2-cholesterol. Gradient gel electrophoretic analysis showed an increase (P less than .01) in the relative concentration of HDL2b (subspecies of diameter 10.57 nm) with a decrease (P less than .01) in the concentration of HDL2a (9.16 nm) plus HDL3a (8.44 nm) with the high-fat diet, but no significant or consistent change with the high-carbohydrate diet. There was no change in the level of the apolipoprotein E-rich HDL subfraction with either diet. Plasma lecithin:cholesterol acyltransferase activity decreased (P less than .05) with the high-fat diet but not with the high-carbohydrate diet. Thus, diet can strongly influence the changes that occur in plasma lipoprotein concentrations during prolonged low-intensity exercise.

Abstract
Fifty-five healthy, sedentary, nonsmoking, and nonobese 24- to 26-year-old men who had low plasma concentrations of high density lipoprotein (HDL) cholesterol were selected for a study of the effect of short-term exercise on plasma lipid and lipoprotein concentrations. The participants were randomized into two groups. Of these, 28 were assigned to a 9-week program of submaximal aerobic exercise three times weekly, and 27 were assigned to a nonexercising control group. Changes in physical fitness were assessed by increments in estimated maximal oxygen consumption; this increased by 15% in the exercise group (p less than 0.001) but remained unchanged in the control group. During the study, body weights and skinfold thicknesses of both groups remained essentially unchanged after 9 weeks. There was no significant difference between the trial groups in total cholesterol, HDL cholesterol, calculated low density lipoprotein cholesterol, or in the HDL2 and HDL3 subfractions. Triglyceride levels were lower by 19 mg/dl in the exercise group as compared to the control group (p less than 0.05). We conclude that moderate aerobic exercise of 9 weeks duration in the absence of weight loss in young males with initially low HDL cholesterol did not influence their HDL cholesterol levels.

Abstract
The acute effect of running a 42.2 km marathon race on plasma lipoproteins was investigated in 12 female subjects (aged 21 to 41 years). During the race there was a significant increase (P less than 0.01) in the concentration of total plasma cholesterol. The mean post-race concentration of high density lipoprotein cholesterol (HDL-C) was 64.0 +/- 16.2 (SD) mg 100 ml-1, compared with 52.1 +/- 14.0 mg 100 ml-1 before the race, representing a significant increase (P less than 0.002). There was no significant difference in the concentration of very low density lipoprotein (VLDL) or low density lipoprotein (LDL) before and after the exercise. The mean concentration of the cholesteryl ester moiety of the HDL increased from 43.7 +/- 12.3 to 54.3 +/- 15.7 mg 100 ml-1 (P less than 0.002), while there was no significant changes in the concentration of the unesterified cholesterol, phospholipid, triacylglycerol or protein moieties of the HDL. The relative proportions of apolipoproteins A-I, A-II, C and E remained unchanged during the exercise. The changes in the concentration of each of the lipoprotein fractions observed during the marathon varied considerably between subjects. The individual increases in the concentration of HDL-C ranged from 4.1 to 28.4 mg 100 ml-1, while both increases and decreases in individual concentrations of VLDL and LDL as well as of total plasma cholesterol were observed. These observations suggest that women undergo greater changes in HDL-C concentration that men during acute exercise, while considerable variation between individuals occurs.
