The Effect of Different Exercise Modalities on Sertoli-germ Cells Metabolic Interactions in High-fat Diet-induced Obesity Rat Models: Implication on Glucose and Lactate Transport, Igf1, and Igf1R-dependent Pathways.

The study aimed to uncover a unique aspect of obesity-related metabolic disorders in the testicles induced by a high-fat diet (HFD) and explored the potential mitigating effects of exercise modalities on male fertility. Thirty mature male Wistar rats were randomly assigned to control, HFD-sole, moderate-intensity exercise with HFD (HFD+MICT), high-intensity continuous exercise with HFD (HFD+HICT), and high-intensity interval exercise with HFD (HFD+HIIT) groups (n=6/group). Intracytoplasmic carbohydrate (ICC) storage, expression levels of GLUT-1, GLUT-3, MCT-4, Igf1, and Igf1R, and testicular lactate and lactate dehydrogenase (LDH) levels were assessed. ICC storage significantly decreased in HFD-sole rats, along with decreased mRNA and protein levels of GLUT-1, GLUT-3, MCT-4, Igf1, and Igf1R. The HFD-sole group exhibited a notable reduction in testicular lactate and LDH levels (p<0.05). Conversely, exercise, particularly HIIT, upregulated ICC storage, expression levels of GLUT-1, GLUT-3, MCT-4, Igf1, and Igf1R, and enhanced testicular lactate and LDH levels. These results confirm that exercise, especially HIIT, has the potential to mitigate the adverse effects of HFD-induced obesity on testicular metabolism and male fertility. The upregulation of metabolite transporters, LDH, lactate levels, Igf1, and Igf1R expression may contribute to maintaining metabolic interactions and improving the glucose/lactate conversion process. These findings underscore the potential benefits of exercise in preventing and managing obesity-related male fertility issues.

Exercise and Urtica Dioica extract ameliorate mitochondrial function and the expression of cardiac muscle Nuclear Respiratory Factor 2 and Peroxisome proliferator-activated receptor Gamma Coactivator 1-alpha in STZ-induced diabetic rats.

INTRODUCTION: Diabetes mellitus can affect and disrupt the levels of PGC1α and NRF2 proteins in the mitochondrial biogenesis pathway. Considering the anti-diabetic properties of Urtica Dioica extract and exercise, this study aimed to investigate the beneficial effects of Urtica Dioica extract and endurance activity on PGC1α and NRF2 protein levels in the streptozotocin-induced diabetic rat heart tissue. MATERIALS AND METHODS: 58 male Wistar rats were divided into five groups (N = 12) including: healthy control (HC), diabetes control (DC), diabetes Urtica Dioica (D-UD), diabetes exercise training (DT), and diabetes exercise training Urtica Dioica (DT-UD). Diabetes was induced intraperitoneally by STZ (45 mg/kg) injection. Two weeks after the induction of diabetes, the rats were stimulated to carry out the exercise (moderate intensity/5day/week) and the gavage of UD extract (50 mg/kg/day) was administered to the rats for six weeks. In this study, the western blotting method was used to measure the levels of PGC1α and NRF2 proteins. Moreover, cardiography was used to evaluate the functional parameters of the heart (ejection fraction & fractional shortening). Finally, the bioluminescence and ELISA methods were used to determine the content of adenosine triphosphate and citrate synthase. RESULTS: The cardiac function parameters, the mitochondrial ATP and the CS content in DC group mice were impaired in comparison with the other study groups and showed a decreasing trend (P < 0.001). The treatment with EX + UD extract was able to minimize the rate of these disorders and acted as a protector of mitochondrial function. There were significant differences in the expression levels of NRF2 (F = 17.7, P = 0.001) and PGC-1α (F = 43.7, P = 0.001) mitochondrial proteins among the different groups. The levels of these proteins were significantly reduced in the DC group in comparison with the HC group (P < 0.001). The treatment with EX or UD extract increased the expression of PGC-1α and NRF2 proteins in the heart muscle of animals in the DT and D-UD groups in comparison with the DC group (P < 0.05). Moreover, the expression of these proteins was more pronounced in the DT-UD group. There was not a significant difference between the DT-UD group and the HC group regarding the expression of these proteins (P > 0.05). CONCLUSIONS: The results of this study showed that treatment with EX and UD extract could treat the disorders which were caused by diabetes in the parameters of cardiac function. Moreover, it was able to improve the expression of the levels of proteins which were involved in mitochondrial biogenesis and its function. Finally, this kind of treatment could attract more attention to the roles of EX and UD extract in the prevention of cardiovascular complications in future studies.

Moderate-Intensity Exercise Training in Association with Insulin Promotes Heat Shock Proteins 70 and 90 Expressions in Testicular Tissue of Experimental Type 1 Diabetes.

OBJECTIVE: The current research was designed to analyze the effect of moderate-intensity exercise training (MEXT), solely and simultaneous with insulin, on the network between oxidative stress and Hsp70 and Hsp90 chaperones after experimental type I diabetes (DM) induction in rats. MATERIALS AND METHODS: In the experimental study, 36 mature Wistar rats were assigned into control and experimental type I DM-induced groups, and then the diabetic animals were categorized to sedentary type I DM-induced (SDM), exercise training-sole without DM (E), exercise training DM-induced (EDM), insulin-treated sedentary DM-induced (ISDM), and exercise training insulin-treated DM-induced (EIDM) groups. After 6 weeks, Johnson's score was evaluated to analyze the spermatogenesis ratio. RESULTS: The Hsp70 and Hsp90 expression levels, testicular total antioxidant capacity (TAC), protein peroxidation ratio, testicular DNA fragmentation ratio, and mRNA damage were investigated. The animals in EDM and EIDM groups (solely and simultaneously) represented a significant (P<0.05) improvement in Johnson's score, spermatogenesis, and TAC ratios versus SDM animals. Moreover, the DM-induced DNA and mRNA damage and protein peroxidation ratio were significantly (P<0.05) recovered in EDM and ISDM groups, which was more remarkable in the EIDM group. The EDM and EIDM groups exhibited significant (P<0.05) increment in Hsp70 and Hsp90 expression levels versus the control and SEDT1 animals. However, the EIDM group exhibited no significant changes compared to the control animals. CONCLUSION: The EX could ameliorate the EDT1-induced detrimental impact by up-regulating Hsp70 and Hsp90 expressions. Meanwhile, it exerts potentially more effective impact, when it is considered simultaneously with insulin therapy.

Effect of moderate exercises and curcumin on hepatic transcriptional factors associated with lipid metabolism and steatosis in elderly male rat.

BACKGROUND AND PURPOSE: The specific molecular mediators involved in dyslipidemia in older people are not yet clearly understood. The current study was, thus, an attempt to investigate whether moderate aerobic exercises and curcumin administration alleviates the abnormalities caused by aging in the rats' liver. EXPERIMENTAL APPROACH: Thirty-two eight-year-old young rats were classified into five groups, namely, young control, aged control, aged-curcumin, aged-exercise, and aged-curcumin-exercise co-treatment. The rats in the exercise groups were trained on an animal treadmill for 60 min/day five times per week for eight weeks. FINDINGS/RESULTS: The results revealed a significant increase in FAT/CD36, PTP1B, significantly decreased HNF4α genes expression, increase in LDL and cholesterol in the aged group compared to the young control. Compared to those in the young control group, no significant changes in HDL and TG amounts in the aged control were observed. Moreover, compared to the young control, the aged group showed liver histological changes such as fibrosis and mild or grade 1 steatohepatitis. Moderate aerobic exercise and curcumin alone or in combination completely masked this effect. CONCLUSION AND IMPLICATIONS: The findings revealed dyslipidemia and liver steatosis related to aging might be partly associated with changes in hepatic transcriptional factors which can be mitigated via moderate aerobic exercise and curcumin.

The effect of aerobic exercise on the expression of mir-126 and related target genes in the endothelial tissue of the cardiac muscle of diabetic rats.

BACKGROUND: The aim of this study was to investigate the effect of 8 weeks of aerobic exercise on the expression of mir-126 and some angiogenesis factors in the endothelial tissue of the cardiac muscle of type 2 diabetic rats. METHODS: Sixteen male Wistar rats were divided into two groups: diabetic control and diabetic training. Nicotinamide and streptozotocin injections were used to induce type 2 diabetes. After familiarization, the training group participated in an 8-week exercise protocol on a treadmill with an intensity of 25 m per minute, a slope of 5% and 30 min per session. RT-PCR was used to evaluate the expression of mir-126 and PI3K genes. Expression of raf1, VEGF, blood glucose and insulin was determined by ELISA and insulin resistance was assessed by HOMA-IR homeostasis model. Immunohistochemistry was used to measure the capillary density of the cardiac muscle. Data were analyzed by t-test for independent groups with a significance level of p < 0.05. RESULTS: Diabetes reduces angiogenesis in cardiac tissue, which is associated with a significant reduction in the expression of mir-126, raf1, VEGF and PI3K; while aerobic exercise increased the expression of mir-126, raf1, PI3K, VEGF. Exercise also decreased blood glucose levels and insulin resistance. CONCLUSION: It seems that aerobic exercise can prevent the destructive effects of diabetes by activating the angiogenic pathway of cardiac tissue. Therefore, regulatory processes through mir-126, which are influenced by aerobic exercise, can be a valuable strategy in developing new treatments for diabetes.

Different continuous exercise training intensities induced effect on sertoli-germ cells metabolic interaction; implication on GLUT-1, GLUT-3 and MCT-4 transporting proteins expression level.

Despite other tissues, the effect of different exercise training protocols (ETPs) on the expression levels of metabolic substrates transmembrane transporters in the testicular tissue, remains completely unexplored. Thus, the effects of low, moderate and high-intensity ETPs on the SCs and germ cells potentials in GLUT-1, GLUT-3 and MCT-4 expression levels was investigated in this study. The animals were assigned into 4 groups, including sedentary control, low-intensity continuous (LICT), moderate-intensity (MICT) and high-intensity (HICT) ETPs-induced groups (n = 6/group). The GLUT-1, GLUT-3 and MCT-4 expressions, cytoplasmic carbohydrate storages of SCs and germ cells, the SCs survival and the spermatogenesis and spermiogenesis rates were assessed. The LICT and MICT did not significantly alter the protein expression levels of GLUT-3 and MCT-4 in the SCs and germ cells, while decreased the GLUT-1 protein content versus the sedentary control animals. In contrast, the HICT remarkably suppressed the GLUT-1 and MCT-4 in both SCs, and germ cells and diminished GLUT-3 in SCs and increased in the germ cells. No significant changes were revealed in the cytoplasmic carbohydrate storage in the LICT and MICT groups, while significantly diminished in the HICT group. The HICT group showed a failed spermatogenesis and spermiogenesis, which were not demonstrated in the sedentary control, LICT and MICT groups. In conclusion, the HICT, by reducing the GLUT-1, GLUT-3 and MCT-4 protein contents in the SCs and reducing the SCs survival, can suppress the glucose transmembrane transport and inhibit the lactate export from SCs, which in turn, ends with failed spermatogenesis and spermiogenesis.

Effect of moderate-intensity exercise training on GDNF signaling pathway in testicles of rats after experimental diabetes type 1 induction.

AIMS: The spermatogenesis failure is reported as the main complication for diabetes and the moderate-intensity exercise (EX) is shown to ameliorate the diabetes-induced impairments both at spermatogenesis and sperm levels. Thus, the current study was done to investigate the possible effect of EX in the sole and simultaneous form with insulin on the network between Sertoli and spermatogonial stem cells (SSCs) by focusing on niche factor Glial cell-derived neurotrophic factor (GDNF). METHODS: For this purpose, 30 mature male Wistar rats were divided into control and experimental type 1 diabetes (T1D)-induced groups. Then the T1D-induced animals were subdivided to sedentary T1D-induced (ST1D), EX + T1D, insulin (INS) + T1D and EX + INS + T1D groups. The general histological changes of testicles, mRNA and protein contents of GDNF and its special receptors gfrα1 and c-RET were evaluated and compared between groups. RESULTS: EX in the sole and simultaneous form with INS significantly (p < 0.05) diminished the T1D-induced histological damages, amplified the GDNF expression, and enhanced the gfrα1 and c-RET mRNA and protein contents compared to ST1D group. CONCLUSION: In conclusion, the EX in the sole form promotes spermatogenesis by up-regulating the GDNF signaling system. Moreover, EX remarkably amplifies the insulin-induced ameliorative effect on spermatogenesis.

Moderate-intensity exercise training ameliorates the diabetes-suppressed spermatogenesis and improves sperm parameters: Insole and simultaneous with insulin.

The current study was conducted to investigate the ameliorative effect of moderate-intensity exercise training insole and simultaneous with insulin on diabetes (DM)-induced pathogenesis at the testicular tissue and sperm level. For this purpose, 36 mature male Wistar rats were divided into six groups, including sedentary control (Con), exercise training (EX), sedentary experimental DM-induced (SDM), exercise training + DM-induced (DM + EX), insulin-treated sedentary DM-induced (DM + INS) and exercise training and insulin-treated DM-induced (DM + INS + EX) groups. Following DM induction, the 6-week exercise training intervention (30 min of moderate-intensity running on a treadmill, once daily [5 days/week]) was considered in EX groups. The tubular differentiation (TDI) and spermiogenesis (SPI) indices, testicular total antioxidant capacity (TAC), superoxide dismutase (SOD) and glutathione peroxidase (GPX) contents, serum testosterone and insulin levels, the apoptosis ratio and sperm parameters were assessed. The exercise in sole (EX) and simultaneous forms with INS (DM + INS + EX group) ameliorated the DM-suppressed spermatogenesis and spermiogenesis indices, up-regulated the serum testosterone and insulin levels, enhanced testicular SOD content, inhibited the apoptosis and improved almost all sperm parameters. In conclusion, exercise training, when simultaneously considered with insulin, fairly boosts the insulin-induced impacts, including the up-regulated testicular endocrine and antioxidant status, spermatogenesis and sperm quality.

Moderate-intensity Exercise Training in Sole and Simultaneous Forms with Insulin Ameliorates the Experimental Type 1 Diabetes-induced Intrinsic Apoptosis in Testicular Tissue.

The aim of this study was to investigate the ameliorative effect of moderate-intensity exercise training in sole and simultaneous forms with insulin on experimental type 1 diabetes (T1D)-induced apoptosis. A total of 36 mature male Wistar rats were divided into six equally sized groups, including sedentary control (Con), moderate-intensity exercise training (E-sole), sedentary T1D-induced (D-sole), moderate-exercise-trained T1D-induced (DE), insulin-treated sedentary T1D-induced (DI) and exercise-trained, and insulin-treated T1D-induced (DEI) groups. The 6-week exercise training intervention was involved 30 min of moderate-intensity running on a treadmill once daily (5 days/week). Next, tubular differentiation (TDI) and spermiogenesis (SPI) indices were assessed. The Bcl-2, Bax and caspase-3 expressions were determined using RT-PCR, immunohistochemistry and western blot techniques. Finally, the TUNEL staining was used to analyze the apoptosis ratio. The moderate-intensity exercise training in the sole and when simultaneously considered with insulin (DEI) maintained testicular cellularity, up-regulated Bcl-2 expression, reduced Bax expression and ameliorated the diabetes-induced apoptosis. We failed to show remarkable alterations in caspase-3 mRNA and protein levels in the DE group versus D-sole animals. In conclusion, the moderate-intensity exercise training is able to potentially protect testicular cells from T1D-induced intrinsic apoptosis via up-regulating Bcl-2 and downregulating Bax expressions. Moreover, it amplifies the insulin-induced anti-apoptotic impacts.

Nandrolone administration with or without strenuous exercise increases cardiac fatal genes overexpression, calcium/calmodulin-dependent protein kinaseiiδ, and monoamine oxidase activities and enhances blood pressure in adult wistar rats.

Misuse of anabolic androgenic steroids (AAS) increases prevalence of cardiovascular abnormalities in athletes, and the underlying molecular mechanism involved in those abnormalities continues to be investigated. The aim of this study was to investigate the effect of chronic nandrolone exposure on alpha and beta-myosin heavy chain (MHC) isoforms gene expression transition, blood pressure related parameters, calcium/calmodulin-dependent protein kinaseIIδ (CaMKIIδ), and monoamine oxidase (MAO) activities in rats' hearts. It was also planned to evaluate the effect of strenuous exercise on cardiac abnormalities induced by nandrolone. Thirty-two male wistar rats were assigned into four groups, namely control, nandrolone, nandrolone with strenuous exercise, and strenuous exercise groups. Nandrolone consumption significantly increased systolic, diastolic, pulse and dicrotic pressure, mean arterial pressure, as well as the amplitude of first peak (H1). Moreover, exercise combined with nandrolone completely masked this effect. The mRNA expression of ß-MHC and the ratio of ß -MHC/α -MHC showed a significant increase in the nandrolone and nandrolone with strenuous exercise groups compared to those in the control group. The values of heart tissue calcium/calmoldulin-dependent protein kinase IIδ (CaMKIIδ), and monoamine oxidase (MAO) in the nandrolone, nandrolone with strenuous exercise and exercise groups were significantly higher than those values in the control group. These findings indicate that nandrolone-induced heart and hemodynamic abnormalities may in part be associated with MHC isoform changes and Ca2+ homeostasis changes mediated by increased CaMKIIδ and MAO activities and that these effects can be provoked via strenuous exercise.

The effect of short-term coenzyme Q10 supplementation and pre-cooling strategy on cardiac damage markers in elite swimmers.

Strenuous physical exercise and hyperthermia may paradoxically induce oxidative stress and adverse effects on myocardial function. The purpose of this study was to investigate the effect of 14-d coenzyme Q10 (CoQ10) supplementation and pre-cooling on serum creatine kinase-MB (CK-MB), cardiac Troponin I (cTnI), myoglobin (Mb), lactate dehydrogenase (LD), total antioxidant capacity (TAC), lipid peroxidation (LPO) and CoQ10 concentration in elite swimmers. In total, thirty-six healthy males (mean age 17 (sd 1) years) were randomly selected and divided into four groups of supplementation, supplementation with pre-cooling, pre-cooling and control. During an eighteen-session protocol in the morning and evening, subjects attended speed and endurance swimming training sessions for 5 km in each session. Blood sampling was done before (two stages) and after (two stages) administration of CoQ10 and pre-cooling. ANCOVA and repeated measurement tests with Bonferroni post hoc test were used for the statistical analysis of the data. There was no significant statistical difference among groups for the levels of CK-MB, cTnI, Mb, LD, TAC, LPO and CoQ10 at the presampling (stages 1 and 2) (P>0·05). However, pre-cooling and control groups show a significant increase in the levels of CK-MB, cTnI, Mb, LD and LPO compared with the supplementation and supplementation with pre-cooling groups in the post-sampling (stages 1 and 2) (P<0·05), except for the TAC and CoQ10. Consequently, CoQ10 supplementation prevents adverse changes of myocardial damage and oxidative stress during swimming competition phase. Meanwhile, the pre-cooling strategy individually has no desired effect on the levels of CK-MB, cTnI, Mb, LD, LPO, TAC and CoQ10.

Effect of Short-term Coenzyme Q10 Supplementation and Precooling on Serum Endogenous Antioxidant Enzymes of Elite Swimmers.

Emami, A, Tofighi, A, Asri-Rezaei, S, and Bazargani-Gilani, B. Effect of short-term coenzyme Q10 supplementation and precooling on serum endogenous antioxidant enzymes of elite swimmers. J Strength Cond Res 32(5): 1431-1439, 2018-This study aimed to investigate the effect of the use of a 2-week precooling strategy and supplementation coenzyme Q10 (CoQ10) on superoxide dismutase (SOD), catalase (CAT), and serum glutathione peroxidase (GPx) in elite, adolescent swimmers during heavy and regular trainings and recording of freestyle swimming. Thirty-six healthy males (mean ± SD; age: 17.5 ± 1.1 years, body fat content: 14.55 ± 1.75%) were randomly selected and divided into 4 groups of CoQ10 (300 mg·d), precooling (immersion in the water at 18 ± 0.5° C), supplementation with precooling, and control, each with 9 participants. During an 18-session protocol in the morning and evening, participants attended speed and endurance trainings for 5 km every session. A 3-stage blood sampling was conducted before the first recording and before and after the second recording in 800, 200, and 50 m. Repeated measurement and the Bonferroni correction were used for the statistical analyses of the data (α = 0.05). According to the results, there was no significant difference between the mean serum level of SOD, CAT, and GPx in the groups at the first stage of blood sampling (p > 0.05). At the third stage, a significant difference was observed among all groups (p < 0.05). At the second stage, precooling and control groups show a significant increase compared with the supplementation and supplementation with precooling groups (p < 0.05). As an antioxidant essential for adenosine triphosphate synthesis, CoQ10 supplementation prevented adverse changes of antioxidant enzymes during heavy trainings and swimming recording and decreased the serum level, while precooling individually increased serum level of antioxidant enzymes by itself.

Nandrolone administration with or without strenuous exercise promotes overexpression of nephrin and podocin genes and induces structural and functional alterations in the kidneys of rats.

Among the various adverse effects of nandrolone administration with or without strenuous exercise, kidney abnormalities, where there are associations between nandrolone decanoate consumption, have not been well defined yet. The aim of this study was to investigate the effect of nandrolone decanoate intake with or without strenuous exercise on nephrin and podocin gene expressions, cystatin C, oxidative DNA damage, and histological changes in the kidneys of rats. Thirty-two male wistar rats were assigned into four groups, namely control, nandrolone, nandrolone with strenuous exercise, and strenuous exercise groups. After six weeks of treatment, the results revealed a significant increase in the nephrin and podocin gene expression, plasma cystatin C, and the amount of 8-OHdG in the kidney tissue; as well as a decrease in creatinine clearance in nandrolone and nandrolone with strenuous exercise groups compared to the control group. Moreover, compared to the control group, the nandrolone and the nandrolone with strenuous exercise groups, showed histological changes such as fibrosis and kidney tissue cells proliferation. These findings indicate that nandrolone induces kidney abnormalities, which may in part be associated with overexpression of nephrin and podocin genes mediated by oxidative stress, which was manifested in increased 8-OHdG in kidney tissue.

The effect of nandrolone treatment with and without enforced swimming on histological and biochemical changes in the heart and coronary artery of male rats.

OBJECTIVE: Chronic anabolic androgenic steroid (AAS) consumption increases incidence of cardiovascular abnormalities in athletes and mechanisms underlying those abnormalities continue to be investigated. This study examines whether nandrolone consumption induced cardiac and coronary artery wall abnormalities via oxidative stress. It was also designed to determine whether enforced swimming augmented possible cardiotoxic effects of nandrolone in rat heart. METHODS: Twenty-four male Wistar rats were divided into 3 groups: control, nandrolone, and nandrolone with enforced swimming. Nandrolone group received 10 mg/kg body weight nandrolone 3 times a week for 6 weeks. Nandrolone group with enforced swimming received the same amount of nandrolone and was forced to swim with excess weight of 20% body weight. RESULTS: After 6 weeks of treatment, results indicated proliferation of heart muscle and coronary smooth muscle cells and lipid peroxidation; significant rise in levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), nicotinamide adenine dinucleotide phosphate oxidase, homocysteine (Hcy), apolipoprotein B, low-density lipoprotein, and cholesterol, as well as severe fibrosis in heart tissue and around coronary arteries of nandrolone and nandrolone with enforced swimming groups compared with control group. CONCLUSION: These findings strongly support idea that nandrolone intake by sedentary rats and exercised rats induced heart abnormality mediated by oxidative stress, which was manifest in increased lipid peroxidation, Hcy, and 8-OHdG in heart tissue.

The effect of regular aerobic exercise on reverse cholesterol transport A1 and apo lipoprotein a-I gene expression in inactive women.

BACKGROUND: Atherosclerotic cardiovascular disease is currently a cause of mortality in some parts of the world. The ATP-Binding Cassette Transporter (ABCA1) gene prepares instructions to produce the ATP-binding cassette transporter protein whose operation is for export of phospholipids and cholesterol, outside cells where they are limited to Apolipoprotein A1 (apoA1). Increased ABCA1 activity could inhibit atherosclerosis. OBJECTIVES: In the present study, the effect of aerobic exercise was investigated on gene expression and biochemical parameters. PATIENTS AND METHODS: The participants included 36 inactive women, which were randomly assigned to control (CON) and experimental (EX) groups. The EX group performed 12 weeks of aerobic exercise and the CON group remained inactive. Fasting blood samples were collected 24 hours before the first session and 48 hours after completion of the course. The ABCA1 and APOA1 gene expressions were measured using semi-quantitative-RT-PCR. Data were analyzed by the SPSS software (version 18). RESULTS: A significant increase in blood ABCA1 (EX group P < 0.002, t = - 9.876) and Apo A-I (EX group P < 0.05, t = 2.76) gene expression was shown following the 12 weeks of training. Plasma high-density lipoprotein-cholesterol (HDL-C) concentration increased (P < 0.001, t = 4.90 respectively) while plasma low-density lipoprotein-cholesterol (LDL-C) concentration decreased (P < 0.001, t = 4.27) in the EX group compared with the CON group. CONCLUSIONS: Aerobic exercises can increase ABCA1 and APO-A1 gene expression. Induction of these genes can effectively prevent cardiovascular disease.
