The purpose of this study was to determine the effect of high-intensity circuit training with colostrum supplementation on the body composition and health factors of overweight men.

40 healthy overweight middle-aged men were randomly divided into four groups: exercise and colostrum supplement, exercise and placebo, colostrum supplement and control. The training protocol consisted of three sessions per week for eight weeks. Subjects in the supplement and exercise-supplement group took 20 grams of powdered colostrum mixed with 200 ml of water every other day and then consumed it. Before and after supplementation and exercise, the variables of fat percentage, blood lipid, BMI index and waist to hip ratio were measured.

The results showed that the percentage of body fat in the supplement plus training group was significantly reduced compared to the colostrum supplement and exercise-placebo and control groups. Also, blood lipid, BMI and waist-to-hip ratio index showed a significant decrease in the exercise-supplement group compared to the other three groups.

In general, the interaction of high-intensity circuit training and colostrum supplementation causes a significant reduction in body fat percentage, blood fat, BMI, and waist-to-hip ratio.

Methods and Materials: 

40 healthy overweight men were randomly divided into four groups of exercise and colostrum supplement, exercise and placebo, colostrum supplement and control. The training protocol consisted of three sessions per week for eight weeks. Subjects in the supplement and exercise-supplement group took 20 grams of powdered colostrum mixed with 200 ml of water every other day; then, they consumed them. The variables of fat percentage, blood fat, BMI index and waist to hip ratio were measured in all the subjects before and after supplementation and exercise.

The results showed that the percentage of body fat in the supplemental training group was significantly reduced compared to the colostrum supplement and exercise-placebo and control groups. Furthermore, blood fat, BMI and waist-to-hip ratio index showed a significant decrease in the exercisesupplement group compared to the other three groups.

In general, the interaction of high-intensity circuit training and colostrum supplementation causes a significant reduction in body fat percentage, blood fat, BMI, and waist-to-hip ratio. However, the need for more studies seems necessary considering the limitations of the research.

Angiogenesis is a physiological process leading to capillary density enhancement and better blood distribution in skeletal muscles, which triggers in response to physical training. The present study aimed to investigate the changes in physiological factors involved in angiogenesis in response to circuit or traditional resistance training.

Thirty-six healthy sedentary students who were studying at Shahid Rajaee Teacher Training University of Tehran (age: 22.1±2.3 years; height: 172.7±5.1 cm) volunteered to participate in the study (from October 2021 to February 2022). Following a pre-test to evaluate one repetition maximum (1RM) of selected movements (Leg Press, Leg Curl, Leg Extension, Bench Pull, Seated Row, Biceps Curl), subjects randomly divided into Circuit Resistance training (CRT) (training protocol included 4 circles/3 times a week/8 weeks circuit performance/50-55% 1 Repetition Maximum (1RM), n=12), Traditional resistance training (RT) (training protocol included 8 repetition/3 set/3 time per week/8 weeks of same movements with 75% 1RM followed by 2 minutes break to rest between the sets; n=12) and the control group without any regular training (n=12). We assessed the level of Vascular Endothelial Growth Factor (VEGF), plasma level of growth hormone (GH), and Basic Fibroblast Growth Factor (BFGF) to the mentioned training methods. Data were evaluated by utilizing SPSS version 14.

Present findings showed that CRT and RT protocols resulted in significant increases in post-test compared to pre-test in VEGF (P=0.00), GH (P=0.04), and BFGF (P=0.00). In addition, the magnitude of changes in VEGF and GH were significantly greater than the magnitude of changes in control group in post-test (P=0.03, and 0.001, respectively). Furthermore, there was a strong correlation between absolute values of GH and VEGF (r=0.74 and r=0.71) following CRT (P=0.01) and RT (P=0.02).

This study demonstrated that CRT and RT might enhance angiogenesis through an increase in VEGF, bFGF and GH, leading to better blood distribution in muscles.

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.

Cerebral palsy (CP) is a movement disorder that results from non-progressive motor injuries originating before, during, or immediately after birth. Exercise plays a significant role in motor improvement. This study was conducted to investigate the effect of circuit exercise training on the gross motor function of children with spastic diplegia cerebral palsy.

This clinical trial was performed on 34 cerebral palsy children, who were divided into two equal groups of 17 experimental (circuit training with one session per week of occupational therapy) and occupational therapy group.The GMFM-88 was used to evaluate gross motor function changes before and after 12 weeks of exercise. Circuit exercises training were performed three times a week for 12 weeks. These exercises were designed in three sets and each set consisted of 6 stations. The duration of activity and rest in each station was equal to 30 seconds.

The results of statistical tests showed that all components of gross motor function, in both exercise and occupational therapy group (except lying and rolling) significantly improved (P <0.05). However, in the intergroup comparison, a significant improvement was observed in gross motor function and its components in the circuit exercise training group compared to the occupational therapy group (p = 0.01).

The results of this study showed that circuit exercise trainings with occupational therapy can further improve the performance of gross motor movements in children with Spastic diplegia cerebral palsy compared to occupational therapy.

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.

Exercise or physical activity is one of the main ways for improving health and having a healthy lifestyle. The aim of this study was to investigate the effect of 6-weeks high intensity interval training (HIIT) on Musclin and insulin in overweight female students. In 2017, 20 overweight young female students of Alzahra University (range: 20-28 yrs.) were selected and divided into two groups: control and HIIT. Training group performed high intensity circuit training consisting of six stations (40 s exercise/40 s active recovery) 3 days a week for 6 weeks while control group continued their usual daily activities. Blood samples collected before and after the research period and analyzed for Musclin, insulin and glucose. Repeated measures ANOVA used for statistical testing. After 6 weeks, there were no significant difference between two groups in serum Musclin changes (P ₌ 0.89). Similar results were also observed for glucose (P ₌ 0.54) and insulin resistance (P ₌ 0.15), while these changes were significant in insulin values (P ₌ 0.008). Six weeks of high Intensity Circuit Interval Training, did not affect Musclin levels in overweight female students; due to the lack of relation between Musclin and insulin resistance, this Myokine probably cannot considered as an effective factor in the insulin resistance process and health.

Scientific findings are noted began occurrence of risk factors in childhood particularly concerned with changes in the pattern of body mass index (BMI) and lifestyle. Evidence suggests that some people, despite having normal cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) levels, are still prone to cardiovascular disease. However, those at risk for clinical detection of atherosclerotic heart disease (CHD) should be specifically evaluated for certain clinical indicators. The purpose of this study is to document the effect of a four weeks circuit training program on the level of plasma fibrinogen in trained wrestlers. This quasi-experimental study was performed on 20 young wrestlers from Khorasan (mean age 19.7 years, BMI 25.5 kg/m2 and 3 to 5 years experience in wrestling) in 2012. Subjects during the Calling, voluntarily chosen and randomly divided into control (n=10) and experimental (n=10) groups. Subjects of experimental group received eight sessions per week for four weeks (four days in the morning and evening shifts) were exercised; that each training session was dedicated to wrestling and circuit training based on wrestling techniques. Subjects of control group did not perform any exercise in four weeks. Weight, body fat percentage, BMI and fibrinogen were measured before and after exercise. Independent two-sample t-test and paired t-test were used compare variable mean. The Results showed that subjects of experimental group in the amount of body fat, (7% decrease; p=0.002) weight (3.5% decrease; p<0.001), BMI (2% decrease; p<0.001), and fibrinogen (8% decrease; p=0.014) significantly reduced after circuit training. Generally four-week circuit training based on wrestling techniques significantly reduced plasma fibrinogen and appears to reduce body fat percentage of subjects (which is evident in this study) is the reason for the decrease in plasma fibrinogen in experimental subjects which ultimately leads to reduced risk of coronary artery disease and ultimately reducing heart strokes in athletes.
