The present study compares two methods of resistance training on anaerobic power, body composition and skill indicators in futsal players. The statistical sample of this research includes 24 male futsal players with an average age of 20.88 ± 1.98 years randomly divided into 3 groups, which include traditional resistance group (8 people), intense circular resistance group (8 people) and a control group (8 people). people) were divided. All 3 training groups of this research had 3 sessions a week for 90 minutes and regular futsal training, which included ball work and speed movements. The traditional resistance training group was performed with 3 turns, 6 RM intensity, 3 minutes rest between movements, 35 seconds rest between turns, and 5 minutes rest between blocks. Both training protocols were almost similar in terms of training intensity and repetition of movements, but they were different from each other in terms of the duration of the whole training. Variations between and within groups of data were investigated using the two-way mixed analysis of variance test. The results showed that intense circular resistance training, like traditional resistance training, increased anaerobic power (average and peak power), 20m speed, improved body composition (decreased fat percentage and increased muscle mass), decreased best time (FS) and total best time. (TS) in repeated sprints (RSA) and improving agility in futsal players. However, despite the significance of fat percentage in two groups, this amount decreased more in intense circular resistance training than in traditional resistance training (p=0.001). No significant difference was observed in the skill indices of the subjects. According to the obtained results, it can be said that intense circular resistance training is a more suitable training for reducing body fat percentage, especially in futsal players. And it can also be said that the intense circular resistance training protocol (HRC) can be used for speed and anaerobic athletes, especially futsal, who seek to prevent the loss of their strength and speed performance during the season and with the pressure of training and competitions. be useful

According to the obtained results, it can be said that intense circular resistance training is a more suitable training for reducing body fat percentage, especially in futsal players.

Type 2 diabetes is one of the most common metabolic diseases known in the world and is the main cause of death in many countries, affecting many people every year. Chronic hyperglycemia caused by type 2 diabetes causes oxidative stress, therefore this study compared the effect of eight weeks of traditional resistance training and Total Body Resistance Exercise (TRX) on some oxidative and anti-oxidative indicators in women with type 2 diabetes.

Thirty women with type 2 diabetes (age, 40-55 years) participated in the study and randomly were divided into three groups of resistance training (n=10), TRX group (n=10), control group (n=10). The experimental groups performed traditional resistance training and TRX three times a week for eight weeks at an intensity corresponding to 80-65% of a maximum repetition, while the control group did not participate in any training program during this period. Blood samples were taken from all subjects before training and 48 hours after the last training session and were used to determine the serum level of superoxide dismutase (SOD), Glutathione Peroxidase (GPx) and malondialdehyde (MDA). Paired t-test was used to investigate the within-groups differences, and the analysis of covariance using Bonferroni's post-hoc test was used to investigate the differences between groups.

Present study showed that after eight weeks of traditional resistance training and TRX, significant increases in SOD and GPX levels were observed in the two experimental groups (p< 0.05). However, no significant difference was observed in the control group. MDA levels decreased in both traditional and TRX resistance training groups. The results of between-group analysis showed that there is no significant difference between the two groups of resistance training and TRX for SOD, GPX and MDA indices (P>0.05).

Based on said the findings of present study it could be concluded that both training methods can improve oxidative (SOD and GPX) and anti-oxidative (MDA) indices in women with type 2 diabetes.

The purpose of this study was to compare the responses of testosterone, cortisol and creatine kinase in two types of resistance training with and without blood flow restriction. For this purpose, 36 adolescent gymnast boys aged 10 to 14 years participated in a quasi-experimental research design. The subjects (weight 37.11 ± 8.11 kg, height 145.16 ± 11.58 cm, body mass index 17.40 ± 1.77 kg/m2) were randomly divided into three groups; control (n=12), traditional resistance training (n=12), and resistance exercise with blood flow restriction (n=12), respectively. Training protocol includes three motions included leg extension, elbow flexion and bench press. The results of intergroup showed that a variable testosterone after acute exercise in traditional resistance training groups (p=0.653) and resistance exercise with blood flow restriction (p=0.107), was not significant. But changing of cortisol in both groups, traditional resistance training groups (p=0.015) and resistance exercise with blood flow restriction (p=0.015), was significant. creatine kinase increased significantly only in traditional resistance training group (p=0.001). The results showed that in both of them protocol, there was no significant difference between groups in levels of testosterone and cortisol, but in varying creatine kinase was significantly different (p=0.05).

Resistance training as an effective way to get different adaptations of exercise. In the most studies is taken into consideration the increase strength and muscle mass to follow this training method. Recently, it has been considered cardiovascular adaptations such as angiogenesis, increased blood flow to tissue and improve aerobic performance after resistance training. Therefore, the aim of this study was to compare the acute responses to endothelial growth factor-A in two types of resistance training with and without the blood flow restriction.

For this purpose, adolescent gymnast boys aged 10 to 14 years participated in a quasi-experimental research design. The subjects (mean weight 37.11 ± 8.11 kg, height 145.16 ± 11.58 cm, body mass index 17.40 ± 1.77 kg m) were randomly divided into three groups; control (n=12), traditional resistance training (n=12), and resistance exercise with blood flow restriction (n=12), respectively. Training protocol includes three motions included leg extension, elbow flexion and bench press. Blood samples were taken before and half an hour after training. Using T-dependent test to check the results of intergroup and One-Way ANOVA with LSD test was used for evaluating the results of between groups.

The results of inter-group showed that a variable VEGF after acute exercise in traditional resistance training groups (p=0.001) and resistance exercise with blood flow restriction (p=0.001), was significant. The results showed that in both of them protocol, there was no significant difference between groups in levels of VEGF, was not significantly different (p=0.33).

One session Resistance exercise with blood flow restriction compared to high intensity resistance exercise, a similar effect in increasing serum VEGF children athletes and for this reason, such as high intensity resistance exercise seems appropriate to provide Angiogenic adaptation of VEGF and improvement in aerobic performance.
