Lipid profile changes and increased vascular resistance are among the most important cardiovascular risk factors in old age. This study aimed to investigate the effect of 8 weeks of aerobic exercise in water on the lipid profile and plasma levels of endothelin 1 in elderly men with prehypertension.

34 elderly men with prehypertension were randomly divided into two equal groups of exercise in water and control (N=17). Before and after the intervention, blood sampling was done to measure lipid indices and plasma levels of endothelin 1. The Shapiro-Wilk test was used to check the normality of the data, as well as the correlated t-test and the independent t-test respectively was used to check intragroup changes and intergroup differences at a significance level of less than 0.05.

In the training group, fat percentage (P=0.03), weight (P=0.01), body mass index (P=0.01), blood pressure (P=0.001), TG (P=0.00), cholesterol (01 (P=0.02), LDL (P=0.02) and plasma levels of endothelin 1 (P=0.002) had a significant decrease compared to the control group. However, no significant difference was observed in the HDL index of the two groups.

Water exercise, while improving lipid indices, led to a decrease in endothelin-1 levels. It seems that according to the physical conditions of the elderly, performing aerobic exercises in water as a substitute for exercises on land has beneficial effects on the cardiovascular risk indicators of the elderly with high blood pressure; Based on this, experts in the field of sports should pay special attention to this type of exercises in designing sports exercises for the elderly.

Using the best exercise protocol along with taking herbal supplements is one of the methods of managing weight loss and related disorders. The aim of this study was to investigate the interaction effect of polarized exercise with Carvil supplement on lipid profile and metabolic syndrome of obese women.

24 obese women were randomly placed in 3 groups (exercise), (supplement) and (exercise with supplement). The participants of the (exercise with supplement) and (supplement) groups received Carvil three times a day and 2 hours before doing the exercises. Polarized exercises were performed for 4 weeks and 3 sessions per week. Physiological and anthropometric indicators as well as biochemical values ​​were evaluated before the start of training and after the last training session. The data was analyzed using SPSS version 27 software at the significance level (P<0.05).

The results showed that weight, body mass index, and fat mass index were significantly reduced in two groups (exercise with supplements) and (exercise). There was a significant decrease in LDL in the (supplemented with exercise) group, but it was not statistically significant in the other groups due to the observed decreasing trend. A decrease in triglyceride, blood sugar, cholesterol, HDL and insulin levels was observed in all groups, although this decrease was not significant. There was a significant difference in systolic blood pressure in the group (supplemented with exercise) and diastolic blood pressure in the group (supplemented) (P<0.05).

Polarized exercise with Carvil supplement can be effective in improving lipid profile and metabolic syndrome in obese women. However, determining the mechanism and nature of the effect of these exercises along with supplement consumption on lipid profile and metabolic syndrome requires more studies.

One of the main factors in changing the lifestyle of obese people is choosing the correct method of physical activity and following dietary considerations. The purpose of this research was to investigate the effect of eight weeks of circuit training and consumption of red tea on some liver enzymes and lipid profile and insulin changes in obese women.

24 obese women were randomly divided into 4 groups: circuit training, circuit training with red tea consumption, red tea consumption and control. Circuit training was performed for 8 weeks and 3 sessions per week. The subjects of the supplement group also received 2 grams of red tea daily for 8 weeks. Lipid indices, insulin resistance, atherogenic and some liver enzymes were measured before the start of the training program and after the last training session through blood samples. The data was analyzed by Spss software version 21 at a significance level of P≥0.05.

Weight and body mass index were significantly reduced in exercise + supplement and exercise groups (p=0.001). The percentage of fat also decreased significantly in the exercise + supplement and exercise groups (p=0.001 and p=0.004). Total cholesterol levels were significantly reduced in exercise + supplement and exercise groups (p=0.029 and p=0.001). LDL levels were significantly decreased in exercise + supplement and supplement groups (p=0.017 and p=0.037). Triglyceride and HDL levels in the supplement group decreased and increased significantly (p=0.010 and p=0.001). Atherogenic index was significantly decreased in exercise and supplement groups (p=0.021 and p=0.001). ALT liver enzyme levels decreased significantly in the training group (p=0.017).

According to the results of the present study, it seems that the use of circular exercises with the help of red tea is probably considered an effective approach for weight loss.

Obesity as a global challenge is caused by positive energy balance. Increasing the intensity of physical activity is related to reducing the risk of cardiovascular diseases, and probably for this reason, it leads to the improvement of blood lipoproteins. Also, in recent years, special attention has been paid to the role of various plants in reducing blood fats and thus reducing obesity-related diseases. Therefore, the aim of the present study was the effect of 6 weeks of intense interval training with fenugreek supplement on lipid profile and body composition indices of overweight and obese women.

The present semi-experimental study was conducted in Birjand, Iran, in 2019. Forty-eight obese and overweight women with an average age of 29.79±7.8 years and a body mass index of 29.29±2.6 kg/m2 were purposefully selected and randomly divided into 4 groups of 12 including; The groups of exercise + placebo, exercise + supplement, supplement and placebo were placed. The exercise groups performed three sessions of intense interval training protocol (shuttle run) at maximum speed during 6 weeks and every week. Blood sampling was done 48 hours before and 48 hours after the training period and taking supplements. The collected data were analyzed using Shapiro-Wilk, covariance and post-hoc Scheffé statistical tests.

Research findings indicated a significant decrease in TG, in the groups of exercise (p=0.001), supplement (p=0.003) and exercise + supplement (p=0.0001), significant decrease TC in exercise groups (p=0.001), supplement (p=0.001), exercise + supplement (p=0.0001), significant reduction of LDL in exercise groups (p=0.001) p), supplement (p=0.002) and exercise + supplement (p=0.0001), significant weight loss in the groups of exercise (p=0.0001), supplement (p=0.007) and exercise + supplement (p=0.0001), fat percentage in exercise groups (p=0.0001), supplement (p=0.0001) and exercise + supplement (p=0.0001) and BMI in the group exercise (p=0.001), supplement (p=0.001) and exercise + supplement (p=0.0001) and no significant change in HDL (p=0.18) and WHR (0.78) were observed.

According to the results of the present study, it appeared that HIIT exercise along with the consumption of fenugreek supplement could be effective in preventing the occurrence of some diseases related to obesity.

Physical inactivity and high-calorie diets have caused obesity and related metabolic diseases, therefore; The aim of this study was to investigate the effect of obesity induction along with endurance training and diet change on weight changes and lipid profiles of male Wistar rats.

The research method was laboratory type. The research subjects included 25 Wistar rats with an age range of 8 to 12 weeks, which were divided into 5 control and experimental groups by targeted selective sampling according to weight and age conditions. In the first stage, 4 days after the weaning period, the food program was started to fatten the rats. A 5-band treadmill was used for endurance training. The training program of the subjects was 30 minutes per day for 8 weeks at a speed of 8 meters per minute. Dependent t-test and one-way analysis of variance were used to analyze the data.

The results showed that there is no significant difference between the pre-test and post-test of the average weight of the obese group + standard diet + aerobics (p = 0.135) and the obese group + standard diet (p = 0.06). Also, there is no significant difference between HDL averages in any of the groups, but there is a significant difference between LDL averages in the control group and other groups (p<0.001).

It seems that endurance exercise has an effect on weight control when a low-fat diet is included.

The aim of this study was to evaluate the effect of 6 weeks of aerobic, resistance, combination (aerobic + resistance) training on serum leptin levels and cardiovascular risk factors in inactive obese girls.

This research was a quasi-experimental study with a pretest-posttest design with a control group. The statistical sample of this study included 28 inactive obese girls who did not participate in any specific exercise program and were voluntarily selected and randomly divided into 4 groups (control, aerobic, resistance). , Combined) were divided into 7 people. Subjects in the aerobic exercise group (3 sessions per week, 40-60 minutes, 60% -70% of maximum heart rate), resistance training and the combined training group (resistance + Aerobic) practiced three sessions a week. Blood samples were collected one day before and 24 hours after the last training session.

The results of this study showed that the mean difference in the amount of leptin in the experimental group compared to the control group showed a significant decrease (P = 0.001). Also, 6 weeks of aerobic, resistance and combined training (resistance + aerobic) caused a significant reduction in fat mass (P = 0.001), body mass (P = 0.002), cholesterol (P = 0.001) and triglyceride (001). / 0 = P). The results of the variables show a significant increase in the level of high-density lipoprotein (HDL) (P = 0.002).

Combined exercise (resistance + aerobics) seems to be more effective in reducing serum leptin and cardiovascular risk factors in obese people.

Trampoline rebound is one of the recent interesting exercises. The present study aimed to investigate the effect of six weeks of trampoline rebound exercises on cardiovascular indices, body mass index, and lipid profile of obese and overweight women.

The statistical population of the present quasi-experimental study consisted of 20 obese and overweight women in Zahedan ( (BMI) ≤27.5 kg/m2), and randomly assigned to two groups of exercise (n=10) and control (n=10). The subjects participated in four 90-min sessions of rebound trampoline exercises for six weeks using a trampoline mat. Physiological, BMI, and lipid parameters were measured in two stages of pre-test and post-test. Data were analyzed in SPSS software (version 21) using independent and dependent t-test, as well as an ANCOVA test. A p-value less than 0.05 was considered statistically significant.

The results demonstrated a significant decrease in post-test values ​​of LDL (from 92.90±1.52 to 73.10±3.81), cholesterol (from 182.10±1.96 to 166.30±6.32), triglyceride (from 108.30±1.33 to 95.30±5.35), and body mass index (29.44±1.07 to 27.38±1.02), as well as a significant increase in HDL (from 59.60±2.75 to 77.00± 3.09) and Vo2max (from 45.50±1.31 to 57.80±1.31) in posttest of the training group, compared to their pre-test (P<0.05). Furthermore, there were the same changes in these parameters in the exercise group, compared to the post-test values ​​of the control group (P<0.05).

As evidenced by the results of this study, six weeks of trampoline rebound training had beneficial effects on controlling lipid profile, cardiovascular indices, and body mass index of obese and overweight women. This training protocol is suggested to improve these indicators in the same groups with obesity and overweight, especially for the variety of exercises.

Recently, fitness (bodyweight workout), kickboxing and TRX training have become very popular. The aim of the present study was to determine the effect of a period of fitness-kickboxing and fitness-TRX training on some anthropometric indices and cardiovascular risk factors in overweight women.

Forty overweight women were randomly divided into three groups. The control group included fitness training and the experimental group included fitness training with kickboxing and fitness training with TRX. Subjects performed the training for two months (3 sessions per week). Then anthropometric indices with body composition analyzer and blood samples (to measure blood lipid profile) were measured on two occasions (before the beginning of the course and 48 hours after the end of the course). For analyzing data, paired sample t-test and one-way analysis variance with the significant level of p<0.05 were used.

There was a significant difference between body weight (p=0.001), BFM (p=0.009), BMI (p=0.0001), %BF (p=0.037), WHR (p=0.024) and also total cholesterol (p=0.011) in fitness group, a significant difference between BFM (p=0.012), %BF (p=0.003) and WHR  (p=0.002) and also total cholesterol (p=0.009), HDL (p=0.016) and LDL (p=0.0001) in fitness-kickboxing group and a significant difference between body weight (p=0.0001), BFM (p=0.001), BMI (p=0.0001), %BF (p=0.001), WHR (p=0.0001) and also total cholesterol (p=0.001) and LDL (p=0.004) in fitness-TRX in the pre-and post-test (p<0.05). Furthermore, there was a significant difference between %BF (p=0.003) and also HDL (p= 0.021) and LDL (p=0.0001) in three groups after a period of training.

All three trainings somehow influenced anthropometric indexes and cardiovascular risk factors in overweight women. With the comparison of the three groups, it can be concluded that fitness training is more effective on decreasing %BF and LDL, fitness-kickboxing on decreasing %BF and increasing HDL as well as fitness-TRX training on reducing LDL.

Physical activity and exercise through different mechanisms can promote health in individuals.The body's bone tissue can alter glucose and fat metabolism under the influence of physical activity and exercise. Therefore, this study was performed with aim to investigate the effect of high intensity interval training (HIIT) on serum levels of under-carboxylated osteocalcin, insulin resistance and lipid profile in overweight girls.

This randomized controlled clinical trial study was performed on 24 overweight female students (body mass index: 28.58±2.38) in Shahid Chamran University of Ahvaz in 2020. The subjects were randomly divided into two groups of 12-member: HIIT and control. The training group practiced for 6 weeks (3 sessions per week), while the control group did not have any regular physical activity. Blood samples were obtained for measurement of serum level of Osteocalcin, glucose, insulin and lipid profile (48 hours before and after the intervention period). Data were analyzed by SPSS software (version 23) and paired-t and independent t-test. P<0.05 was considered statistically significant.

Performing high intensity interval training for 6 weeks led to an increase in serum levels of under-carboxylated osteocalcin (P=0.045), significant decrease in glucose (P=0.026), insulin resistance (P=0.036), triglycerides (P=0.017) and LDL (P=0.04) in overweight girls; while, no significant changes were observed in other components of lipid profile (total cholesterol and HDL) (P≥0.05).

Performing high intensity interval training led to a significant improvement in insulin resistance and some features of the lipid profile (triglycerides and LDL). This may be due to an increase in the endocrine function of the bone (under-carboxylated osteocellin).

The aim of this study was to evaluate the effect of six months’ resistance training and ginger extract on lipid profiles, body composition and selected liver enzymes in obese menopausal women.

In a semi-experimental trial, 48 obese menopause women were randomly and divided into 6 groups including control, ginger extract, resistance training and resistance training -ginger extract. resistance training was performed 3 sessions in a week, 30-60 minutes for 24 weeks. The subjects consumed ginger extract three times a day in 500 mg capsule for 6 months. 24 hours, 3 months and 6 months after the intervention in the 12-hour fasting condition, subjects from each group received blood samples and anthropometric characteristics. Data were analyzed by two-way ANOVA with repeated measures and Tukey post hoc test at the p<0.05.

Six months of resistance training was associated with a decrease in ALT (p=0.016) and AST (p=0.002) in postmenopausal women, but combined exercise-ginger supplementation was no significant effect on ALT and AST in postmenopausal women (P>0.05).

It seems to Longer Periods Regular resistance exercise compared with combined exercise-ginger supplementation have more health benefits for obese menopause women.

Regular physical activity and diet can be effective in preventing cardiovascular disease. Therefore, the purpose of this study was to investigate the effect of 6 weeks of high intensity interval training (HIIT) with nano-curcumin supplementation on factors related to cardiovascular disease such as lipid profile and C-reactive protein (hs-CRP) in overweight girls.

The research method was randomized-experimental with pre-post test design. 48 overweight student girls with mean age of 21.78±0.94 years and BMI equals 28.12±2.1kg/m2 were randomly divided into four groups: training (n=12), training-supplement (n=12), supplement (n=12) and control group (n=12). Supplement groups consumed a 80 mg nano-curcumin capsule daily. Training groups performed an exercise protocol of HIIT training with maximum heart rate for 6 weeks (three sessions per week). The control group did not have any regular exercise. Blood samples were obtained for measurement of lipid profile serum levels (Low Density Lipoprotein (LDL), Total Cholesterol (TC), Triglyceride (TG) and High-Density Lipoprotein (HDL)) and CRP before and after a 6-week period of exercise and supplementation. Data were analyzed by ANOVA and dependent t-test at P≤0.05.

In the supplement-training group, triglyceride (P=0.03) and CRP (P=0.03) significantly decreased, HDL (P=0.034) significantly increased and LDL and cholesterol did not show significant changes (P≥0.05). But there were no significant changes in lipid profile and CRP in the training and supplement groups (P≥0.05).

HIIT training and nano-curcumin supplementation alone resulted in slight positive changes of lipid profile and CRP. But it seems that doing HIIT training together with nano-curcumin supplementation has a reinforcing effect on each other and they are more effective at preventing cardiovascular diseases.

 Studies have shown that the use of herbal medicines can be effective in prevention and treatment of obesity/overweight and its related disorders. The purpose of the present study was to investigate the effect of nanocurcumin supplementation on anthropometric characteristics, lipid profile and C-reactive Protein (CRP) in overweight girls.

 This is a quasi-experimental study with pretest/posttest design. The subjects were 24 overweight students with a mean age of 22.48±1.64 years and body mass index (BMI) of 27.53±3.29 kg/m2.  After receiving written consent from the subjects, they were randomly divided into two groups of supplement (n=12) and placebo (n=12). Supplement group consumed 80 mg nanocurcumin capsule daily for 6 weeks. Anthropometric indicators (weight, BMI and waist-to-hip ratio) were measured before and after the intervention and blood samples were collected to measure lipid profile parameters (low-density lipoprotein, total cholesterol, triglyceride, and high-density lipoprotein) and CRP level. Data were analyzed by dependent and independent t-tests. The significance level of the tests was set at P≤0.05. 

 Nanocurcumin supplementation for 6 weeks did not significantly affect the anthropometric indicators, lipid profile parameters and CRP level (P>0.05). 

 It seems that the short-term nancurcumin supplementation cannot significantly affect anthropometric characteristics, lipid profile, and CRP level in overweight girls. Therefore, long-term use and different doses of this supplement are recommended.

Cardiovascular diseases, especially atherosclerosis, are among the main causes of mortality in developing countries of Asia and West Asia. The purpose of this study was to investigate the effect of eight weeks of aerobic training on serum lipid profile and fibrinogen in middle-aged men with heart failure.

Twenty men with aged 50 to 60 years, with heart failure grade 1 to 3, and heart power of less than 45% were selected and then randomly divided into experimental and control groups. Aerobic exercise was included of eight weeks of aerobic training with intensity of 35-65% of maximal heart rate with a three-session frequency per week. Fasting blood samples were collected from participants before and after of eight weeks. Data were analyzed by Paired sample t-test and Independent sample t-test.

The results showed that after eight weeks of intervention, mean changes of HDL, TC / HDL ratio and fibrinogen were statistically significant (P<0.05). On the other hand, mean changes in LDL, TG, TC and LDL / HDL ratio were not significant (P>0.05).

The results of this study indicate that performing aerobic exercises along with drug therapy can be useful as a good way to prevent cardiovascular disease in people with heart failure

Cardiovascular disease (CVD) is one of the most important factors of mortality in Postmenopausal women and is most prevalent in postmenopausal women due to the reduced protective role of estrogen. So, this research was done with the aim of effect of 8-week aerobic exercise in water (AW) with or without consumption of Bunium persicum (BP) in levels of hsCRP and lipid profile in postmenopausal inactive women.

This study consisted of postmenopausal and obese women referring to pools in Mashhad who were selected by purposive sampling method and were randomly divided into three groups of 10 each with exercise, supplementation and supplementation whit exercise. Training group for eight weeks (three days) program of aerobic exercise in water with 55-75% of maximum heart rate intensity has eight weeks of supplementation (3 g daily Bunium persicum) consumption and group with both interventions had exercise + supplements. For data analysis, KS test, paired samples t test and one-way ANOVA were used.

Data Analysis showed a significant reduction in levels of hsCRP in BP group (p=0.01) and aerobic power in all three groups had a significant increase (p<0.05), but the changes in hsCRP and aerobic power did not have statistically significant difference between the three groups.

It seems that the daily consumption of BP plays an important role in prevention of CVD occurrence and AW with or without consumption of BP is effective on improvement of aerobic power.

The global epidemic of obesity has affected the general health. The aim of the present study was to compare the effects of low and moderate intensity circuit resistance trainings on the levels of adiponectin and lipid profiles in overweight women.

A total of 54 overweight women [31.56±2.24 years, 80.45±9.4 kg, 28.3±6.21 kg/m2] were randomly assigned into three groups of moderate intensity circuit resistance training (MICT), low intensity circuit resistance training (LICT), and control. Exercise training program was conducted for eight weeks, three sessions per week. Before and after the exercise training program, the levels of adiponectin and lipid profiles were measured. For data analysis, descriptive statistics, analysis of covariance test and Bonferroni post hoc test were used. Data analysis was performed in SPSS, version 20, with the significance level set at p≤0.05.

At the beginning of the study and before applying the exercise protocol, there was no difference in baseline adiponectin between the groups (p>0.05). The results indicated that adiponectin levels significantly increased after eight weeks of moderate-intensity circuit resistance training as compared with control group (p=0.027), but changes in adiponectin levels were not statistically significant in low intensity group (p=0.14). Decrease in the levels of LDL-c (p=0.001), cholesterol (p<0.001), and TG (p<0.001) and increase the levels of HDL-c (p<0.001) were significant in moderate intensity group compared to those of the control group.

According to the results obtained in the present study, moderate-intensity circuit resistance training has been shown to be effective in increasing adiponectin, therefore, the lipid profiles in this group had a significant improvement related to these changes.

It seems that changes in sodium and potassium balance and lipid profile associated with blood pressure levels.  Aerobic exercise as known as a blood pressure levels modified factors. The aims of this study were to investigate the correlations between plasma sodium and potassium changes, lipid profile and blood pressure following aerobic exercise in academic active men.

In This study, 65 academic active men selected with Purposeful sampling as study subjects. Then all subjects randomly allocated in control and experimental (water and out water training) groups. In pre-test and after aerobic exercise with %70 of maximal heart rate intensity, all lipid variable (HDL, LDL, VLDL, TG, TC), blood pressure and plasma sodium and potassium measured.  To compare difference and correlations one-way ANOVA and Pearson correlation used, respectively. 

Correlation between changes in systolic and plasma sodium levels (r=0.86) after an aerobic exercise intervention in water (r=0.88) and outside water (r=0.90) slightly increased. The association of diastolic blood pressure levels with plasma sodium levels (r=0.07) after an intervention in aerobic training in water (r=0.08) and out of water (r=0.11) increased insignificantly. Intervention of aerobic exercise in water and outside water did not have a significant effect on the association of blood pressure with lipid variables (p≥0.05).

Intervention of aerobic exercise in water and outside water has no significant effect on the relationship between systolic and diastolic blood pressure levels with sodium and potassium levels and lipid variables.

Various types of exercise cause damages at cellular levels in muscles. Muscle damages caused by exercise increase levels of C-reactive protein (CRP) in blood. The aim of this study was to assess effects of resistance training and ta-hydroxy beta-methylbutyric acid (HMB) supplementation on responses of high sensitivity C-reactive protein (hs-CRP) and lipid profiles to strenuous activity in adult male rats.

In total, 32 healthy rat were randomly divided into four major groups of training, supplement, training-supplement and control groups. The experimental group carried out eccentric resistance for two weeks, five days a week. Supplementary groups received supplemental HMB daily for up to 450 mg/kg body weight per day using gavage. In general, one session of strenuous eccentric resistance activity (stepping down from ladder with a gradient of 80% by closing 120% 1RM at the back of the rat tails) was carried out 24 h before and after the intervention (supplementary and training). Data analysis was carried out using ANOVA and Tukey post hoc test at P ≤ 0.05.

Results showed that HMB supplementation and eccentric resistance training alone included no effects on hs-CRP, cholesterol, triglycerides, LDL-C and HDL-C in adult male rats after strenuous activity (P < 0.05). However, combination of HMB supplementation and eccentric resistance training included a significant effect on these variables after a strenuous activity in adult male rats (P= 0.001).

Based on the results, combination of supplemental HMB and eccentric resistance training may help improve inflammatory statuses and lipid profiles.
