The aim of this study is to examine the impact of 6 weeks of intermittent intense aerobic training specifically designed for football on professional players' time to reach exhaustion (Tmax), maximal oxygen consumption (VO2max), minimum speed to reach maximum oxygen consumption (vVO2max), and anaerobic threshold (LTP2). Twenty-eight club football players (average age 20.5±4 years, weight 69.8±2 kg, height 175.6±1.2 cm, fat mass 11.59±1.7 kg, fat-free mass 58.56±6.9 kg, body mass index 17.56±3.4 kg/m2) from the Tehran Ground Force team, participating in the Azadegan Cup One Country League, were purposefully selected and randomly divided into two groups: control (n=14) and experimental (n=14). The training regimen included 6 weeks of intermittent intense aerobic exercise (HAF) with 4 sessions per week and six ball movement drills on a specially designed course. The training intensity was set at 75% for the first two weeks, 85% for the following two weeks, and 90% of the maximum heart rate for the final two weeks. Analysis of covariance was used to compare the groups based on the research design (pre-test-post-test with control group) with a significance level of P ≤ 0.05, and data analysis was conducted using SPSS version 18 software. The results of the covariance analysis revealed a significant enhancement in the measured parameters in the experimental group compared to the control group, specifically in VO2max (P=0.023), Tmax (P=0.027), vVO2max (P=0.038), and LTP2 (P=0.041). The findings of this study suggest that after 6 weeks of intensive aerobic training for football (HAF), both aerobic and anaerobic indicators improve in football players.

Peripheral neuropathy is the most important factor in the incidence of foot and amputation in diabetes. the purpose of this study was to investigate the effect of aerobic exercise in water and land on the irritability of sensory of the hands and soles of the diabetic patients. 24 participants were assigned randomly in three groups Control, aerobics on land, aerobics in water. Aerobic training involved 12-weeks (2 times·week-1). Before and after the training period, the marks on the hand and the foot of the patients were measured and recorded by the neurothesiometer machine. MANKOVA and dependent t-test were used to analyze the data. The results of MANKOVA test for intergroup comparisons in the post-test did not show a significant difference in any of the variables of sensory irritability in the soles of the feet and hands between the groups (P≥0.05).The results of intra-group comparisons using dependent t-test showed that aerobic exercise in water has a significant effect on the sensory irritability scores of the palms and soles of the feet of diabetic patients (P≤0.05).However, this significant effect was seen only in the scores of the soles of the aerobic exercise group on land (P≤0.05);Also, the control group did not show a significant difference in any of the variables from pre-test to post-test (P ≥0.05). the result that aerobic exercise in water is due to the creation of hydrostatic pressure, it can have more impact on the bottom of the palm and foot of the diabetic patients.

Positive effects of doing exercise on physiological factors is evident, and findings of cognitive and psychological effects of exercise are expanding. Nowadays, aerobics has become very popular among females. The present study aimed to investigate predictability of aerobics trainers and inactive females via cognitive, perceptual, and attentional variables. To this end, 160 females of Tabriz (19-50 years old) were selected through a random cluster sampling technique. The Wechsler Memory Scale (WMS), spatial cueing test, and short form of Physical Self-Descriptive Questionnaire were used to measure variables and discriminant analysis used for data analyzing. The results showed that all the memory, attention and some of the physical self-perceived features could predict aerobics trainers and inactive females with different percentages; the physical self-perceived variable was the best predictor of aerobics trainers and inactive females. It seems that the effects of exercise on physical self-perception factors is more than cognitive and attention factors.

 Overweight is recognized as one of the biggest health problems in the world. Obesity not only causes limitations in life but also causes many metabolic and respiratory diseases. The best way to reduce this obesity is to balance the energy consumed and consumed. The purpose of the present study was to compare the aerobic and Pilates exercise with weight loss diet on respiratory and anthropometric indices of overweight and obese women.

This experimental study was performed as pretest and posttest in Tehran. Women in their 30s and 50s who were overweight and obese (BMI above 25) were randomly selected and were divided into experimental groups (n = 10) and control (n = 11) (n = 21). Participants in the experimental group were involved in aerobics classes for 8 weeks (3 times a week) and they also went on a weight loss diet. The control group did not have any activity, but they were also given a weight loss diet. Body composition and spirometry were used to measure body composition (Weight, body mass index, lean mass and body fat percentage) and respiratory indics (Forced expiratory volume in 1 second, Forced vital capacity), respectively. Then, using SPSS software version 21, the data were analyzed with t-tests for independent groups.

Weight loss was significant in both aerobic (P = 0.01) and control (P = 0.04). The percentage of body fat and lean mass did not differ significantly between the two groups. Among the respiratory indicators, the volume of forced exhalation increased significantly in the first second in the aerobic group (P = 0.05). Compulsory vital capacity did not differ significantly in either group over 8 weeks (P = 0.15) and (P = 0.37).

8-week aerobic exercise with weight loss diet more effective than diet without physical activity on anthropometric and respiratory parameters and reduce the risk of obesity in people.

This research aims at studying the effect of aerobic sport on capacity of visual memory among sedentary students regards the role of cognitive styles. The sample of this research is 24 ones 20-30 years old female students at University of Tabriz that do not have any record of experience or activity in aerobic sport and put in three groups. Group Embedded Figures and Corsi Block Test were used for gathering information. Aerobic sport training was conducted for 16 sessions in all three groups. Data were analyzed by descriptive and inferential statistical t-test and one-way ANOVA and repeated measure. The results of this research showed that sport activity increased visual memory capacity. But as regards the observed results, no difference was seen in visual work memory in cognitive styles. These results show participants in sport activities can improve cognitive functions like as working memory

Effective use of medications as methadone with exercise training can facilitate the development of healthy. The aim of this study was to compare the effect of different training with methadone on fibrinogen and lipid profile of addicted men.

90 addicted men are treated in prison (36.8 ± 4.3yrs) were randomly divided into six groups (n=15): control, Narcotics Anonymous(NA), aerobic training + methadone, aerobic training + methadone reduction, resistance training + methadone, Resistance training + methadone reduction. Experimental groups performed training for 12 weeks, three sessions in week. Aerobic training consisted of 4 to 8 sets, 3-min at 80–90 % maximum heart rate (HRmax) on a cycle ergometer. Resistance training performed with 8 to 12 repetitions, 3 sets and 70-85% one repetition maximum(1RM). Data were analyzed by SPSS software and Multiple analysis of variance (MANOVA) and Tukey post hoc test at the significant level (P≤0.05).

The high-density lipoproteins (HDL) level of blood in the training groups was significantly increased (P≤00001) compared to the control group. Also, low-density lipoproteins (LDL, P≤0.005), Triglycerides (TG, P≤0/008), Total Cholesterol (P≤0/014 and fibrinogen (P≤00001) levels were significantly reduced in the training groups compared to the control group. Also, the aerobic training groups had a greater effect of all the measured variables than the resistance training.

regular exercise, especially aerobic and resistance exercises with a reduction in methadone has a favorable effect on inflammatory factors and ultimately the health of addicted people

Physical and cognitive activities have positive effects on cognitive functions, but have been rarely applied in combination with each other. Therefore, the aim of present study was to investigate the effect of physical activity with different levels of cognitive load on the cingulate cortex's brain waves. The present study is semi-experimental. 30 sedentary female students with an average age 22.63 ± 1.92 years were selected by convenience sampling and equally divided into three groups (physical activity without cognitive load, physical activity with cognitive load and control). The experimental groups practiced specific training program for 16 sessions, but the control group performed their daily activities. Brain waves, before and after the training program, was recorded using EEG device in resting position and with open eyes. Fz, Cz and Pz data in the Delta, Theta, Alpha and Beta brain waves were analyzed using MANCOVA and Bonferroni post-hoc test in the significant level of 0.05. The results showed a significant decrease for Delta brain wave in Fz and a significant increase for Alpha brain wave in Pz among participants into both experimental groups. On the other hand, there was no significant difference between the effects of physical activity with and without cognitive load on the cingulate cortex's brain waves. According to the findings of the present study, physical activity with and without cognitive load could possibly provide the conditions for stimulation of neurons in the cingulate cortex, which may lead to adaptation in the nervous system.

The aim of this study was to evaluate the effect of two methods of aerobic and resistance training on plasma levels of omentin-1, CRP and aerobic capacity of overweight and obese women. Twenty-two overweight and obese women volunteered to participate in this study. They were randomly assigned in two groups of aerobic (Mean age: 40.64±7.76y, BMI: 30.40±4.94 kg/m2, body fat percent: 27.31%±2.98) and resistance exercises (Mean age: 40.91±6.82y, BMI: 31.69±4.81 kg/ m2, body fat percent: 26.94%±2.99). The aerobic training program included jogging and running activities with 55%-75HRmax for 30-60 minutes, 3 sessions a week, and resistance training included a weight training program with 75% 1RM for 3 sets and 3 sessions per week for eight weeks. Blood samples were collected before interventions and 24 hours after the last training session in a fasting condition. The results showed eight weeks of aerobic and resistance training interventions caused significant decrease in C-reactive protein, and significant increase on Omentin-1 and aerobic capacity of both groups (p<0.001); but there were non-statistically significant differences between C-reactive protein, Omentin-1 levels and aerobic capacity of both groups (p>0.05). The results revealed the effectiveness of both aerobic and resistance training on C-reactive protein, Omentin-1 levels, and cardiorespiratory endurance of both groups. It seems that short term exercise interventions have similar effects on these metabolic indexes.

The purpose of this study was to achieve a non-pharmacological effective way to modify behavioral problems in mothers with ADHD children. The statistical population at Qom city was determined by a general call for mothers with ADHD children, and 20 subjects were selected as samples through simple random sampling.
The research samples were randomly assigned into two equal groups of experimental and control group, and pre-test, post-test and follow-up tests were conducted on them. The experimental group experienced aerobic training 8 weeks, per week 3 sessions for 45 minutes. Anxiety and depression questionnaires of DASS-21 (1995) and life orientation of Sheyer & Carver (1985) and Happiness of Oxford (1989) were used. The ANCOVA’s statistical model was used to analyze data. The findings showed that aerobic exercise in the posttest and follow-up stages reduced the depression and anxiety of mothers of ADHD children and increased their life orientation and happiness in the experimental group. According to the findings of this study, it is suggested that aerobic exercises be used as an appropriate therapeutic strategy, free of side effects, and available to improve the physical and mental health of mothers with ADHD children.

The objective of this study was to perform a narrative review of the literature to determine the adaptations of physiological performance following high-intensity interval training (HIT). High-intensity interval training generally refers to repeated bouts of relatively brief intermittent exercise, often performed with an all-out effort or at intensity close to that which elicits VO2peak. Depending on the training intensity, a single effort may last from a few seconds to up to several minutes, with multiple efforts separated by up to a few minutes of rest or low-intensity exercise. An apparent characteristic of this type of training is the very low training volume. A single high-intensity exercise bout requires the ATP provision of both aerobic and anaerobic metabolism. By increasing the intense frequent bouts and performing in an intermittent practice with recovery among the bouts, the demand of the muscular cells and metabolic pathways will change and then alter contribution of aerobic metabolism for ATP provision. As a result, both aerobic and anaerobic energetic systems are involved in ATP resynthesis. Overall, Physiological adaptations involving in performance improvement following HIT can refer to closed and synchronized interactions of peripheral adaptations (in skeletal muscle), neural (motor unites and CNS) and cardiovascular adaptations. Therefore, by applying this type of training can expect a wide range of metabolic and performance adaptations that result in improvement of both aerobic and anaerobic systems. These findings show that high-intensity interval training with very low volume can cause major adjustments in body and suggests high-intensity interval training is a time-efficient strategy.

The aim of this study was to investigate the effect of aerobic-resistance training on visceral adipose tissue, serum omentin-1 and insulin resistance in ovariectomized (OVX) rats. Fifty Female Wistar rats (weight, 180±5g) were divided accidental and according body weight into five groups: SHAM (n=20) and OVX (n=30) groups. OVX rats were subdivided into 2 Ovx+sedentary (Sedentary; n=20) groups and one aerobic-resistance training (Ovx+Exe; n=10) group. Two weeks after surgery, one group of OVX rats and one group of SHAM rats were sacrificed and omentin-1, insulin resistance and visceral fat were measured. The other OVX rats were randomly divided into the following subgroups: 1) OVX and sedentary (Sedentary); 2) OVX and Exercise (Ovx+Exe). The exercise consisted of 8 weeks of aerobic-resistance exercise (3 days/week, 20 m/min, 60 min/day, 10% slope, Load; 3% body weight, attached to tail), three days a week. After complete anesthesia, the abdominal cavity was rapidly opened and blood samples were collected. All intraabdominal fat were dissected out and weighed immediately. Omentin-1 was measured by rat omentin ELISA kit. HOMA-IR was used to estimate the insulin resistance. There was no significant differences between weights means all groups. After two weeks of surgery, there was no significant difference between visceral fat, omentin-1 and HOMA-IR in SHAM2 compared to OVX2. After eight weeks, combined aerobic-resistance training in Ovx+Exe significantly decreased visceral fat gain induced via ovariectomy by 21/4% compared to the level observed in Sedentary; whereas, visceral fat significantly increased by 92.5% in OVX2 compared to SHAM2 (p<0.05). Omentin-1 increased in Ovx+Exe compared to Sedentary and SHAM, by56/5% and51/6%, respectively; whereas it was significantly decreased by3/1% in Sedentary compared to SHAM (p<0.05). HOMA-IR induced via ovariectomy significantly decreased by74.7% in Ovx+Exe compared to Sedentary; whereas, it significantly increased by 193.7% in OVX2 compared to SHAM2 (p<0/05). Also, HOMA-IR decreased in Ovx+Exe compared to SHAM2, but it was n ́t significant. 8 week aerobic-resistance training successfully decreased visceral fat and insulin resistance via increasing omentin-1. So, it seems that 8-week aerobic-resistance training with 70-85% Vo2max is suitable for controlling body weight gain, decreasing visceral fat and insulin resistance and increasing omentin-1 in menopause period.

Cortisol and BDNF are two factors that affect the human brain neurogenesis. The purpose of this study was to comparison the effect of two exhaustive aerobic and anaerobic physical activity on serum BDNF and cortisol levels and their relationship together in active men. 16 active students divided into two groups randomly. Tests used in this study consisted of Cunningham and Faulkner test for anaerobic group and Astrand test for aerobic group. blood sample was taken before and immediately after exhaustion. T-test results showed that both acute exhaustive anaerobic and aerobic exercise increases significantly BDNF level (P<0/05). Also, Serum cortisol levels following Implementation of aerobic and anaerobic exercise to exhaustion decreased significantly (P<0/05) and increased non significantly (P>0/05), respectively. There was no significant correlation between cortisol and BDNF levels in the two groups. Likewise, independent samples t-test showed no significantly different between aerobic and anaerobic groups in BDNF and COR levels. The present results indicate exhaustive aerobic and anaerobic exercise had significant and positive impact on serum BDNF. Due to the lack of correlation between these two factors can be stated that probably run acute aerobic and anaerobic activity is not increased COR to the extent that suppresses BDNF levels in active individuals, therefore is not a threat to the health of the nervous system.

The purpose of this research was study of acute effects of aerobic exercise, core stability exercise and static stretch on elite women shooters performance. For this Sixteen female shooters participated in the study randomly assigned to four groups of Aerobic: five minutes of aerobic activity, Core stability: five-minute Core stability movements on the floor, stretch: five-minute total body static stretching and Control. All subjects carried out four protocols in two consecutive days as the cross design. After each Protocol, participants performed 20 shots with air pistol. Shooting performance analyzed by Scatt Shooting Training System. The data analyzed by the ANOVA with repeated measures method. Aerobic group's Record, significantly higher than other groups. Shot group was higher between aerobic with core stability and stretch groups, significantly. It was shown significant difference between aerobic group with stretching and control groups, in the stability on center of target. However, the difference in fluctuations of the aiming point was not significant between four groups. The results suggested that moderate intensity aerobic in a way that engages the neuromuscular coordination can improve shooting performance.
