The aim of this study was to investigate the effects of resistance training on serum Vascular Endothelial Growth Factor (VEGF), basic Fibroblast Growth Factor (BFGF) and plasma level Growth Hormone (GH) and cortisol on sedentary individual men. Therefore, we chose twenty sedentary students who divided in two groups resistance training (RT) (age 24.1 year, height 172.7 cm, weight 67.20 kg, BMI 18.93 kg/m2, %fat 17.6) and control (age 23.6 year, height 173.3 cm, weight 66.2 kg, BMI 20.66 kg/m2, %fat 20.59). After initial blood sampling, Resistance training circle group were active in the period of five weeks, the control group did not exercise in these periods. Finally, to remove temporarily the effects of exercise blood samples were taken 48 hours after the last training session. All data analysis at the significant level P≤0.05 was performed using SPSS 18 software. Independent t-test results showed that resistance training following values level of VEGF (P=0.033) Growth Hormone (P=0.001) compared to control group increased significantly whereas cortisol (0.266) and bFGF (0.086) in between resistance and control group variation non-significant. The test results show that followed by resistance training in posttest, there is a high correlation between values growth hormone and VEGF (r=0.74), the correlation is significant (P=0.014). It seems that resistance training can be increase vascular endothelial growth factor and growth hormone, thereby enhance angiogenesis.

The purpose of this study was to determine the effects of two resistance exercise protocol at different rest intervals on creatine kinase (CK) and lactate dehydrogenase (LDH). For this purpose, twenty untrained men (age 22.5±1.6 yr; high 174±3.4 cm; weight 73.2±3.5 kg) voluntarily participated in the research and randomly assigned in one of two resistance exercise group at rest intervals of 90 s (n=10) and 180 s (n=10). Resistance exercise was done with six repetitions maximum (85%1RM) in four sets. Blood samples were collected from the antecubital vein at pre exercise, immediately post exercise, 6, 24 and 48 hours post exercise. The results indicated that CK and LDH enzymes significantly increased at 24h post-exercise in both groups and continued for 48 hours’ post-exercise (P≤0.0001). But, there were no significant difference of interaction of time × resistance exercise in the CK (P=0.767) and LDH (P=0.250) between groups. It means rest interval between sets did not effect on changes mentioned enzymes. Generally, it can be concluded that rest time intervals between Sets in resistance exercises don't affect cellular damage.

The aim of this study was to determine, the effect of acute consumption of caffeine on maximum strength, muscle endurance (number of repetitions to exhaustion) and the blood lactate in the two different intensity of resistance exercise in trained men. Sixteen bodybuilders (mean age 7.3±50.25 years, Height 27.5 ± 37.177 cm and weight 14.2±5.87 kg) were selected. In the first session the participants performed one repetition maximum (1RM) test after taking placebo capsules, while in the second session they took capsules which contained caffeine (6 mg/kg). In the third session, the participants took placebo capsules and performed repetitions to exhaustion in two tests with 60% 1RM. The levels of blood lactate were immediately measured at this point. In the fourth session, they took caffeine and the same protocol of the third session was executed. In the fifth session, placebo was introduced and the participants performed repetition to exhaustion for the two testes with 80% 1RM and then lactate levels of blood were measured. The next session entailed taking caffeine and the participants did the previous session protocol. The results of independent-samples T-test analysis (P=0.05) showed that caffeine consumption, as compared to placebo, significantly affected the number of repetition to exhaustion with 60% intensity 1RM in leg press item, while there was no significant change in other variables. Consequently, it seems that acute caffeine consumption has increased the number of repetition to exhaustion in low intensity particularly for lower body movements.

The purpose of the present study was to describe body composition and anthropometric profile of Iranian football league referees and their relation to the specific fitness tests. Subjects included 70 Iran Premier League men referees as samples that were targeted and accessible. Indices of anaerobic, aerobic performance, body composition and anthropometrics were measured using a standard configuration of the National Football Academy. To determine the relationship between the variables the correlation coefficient of Pearson was used. Iranian football league referees had mean age of 36.37±4.45 years, height of 179.59±6.05 cm, body mass of 75.53±6.2 kg, %BF of 15.11± 3.97, VO2MAX of 54.57±2.82 ml/kg/min and peak & average anaerobic powers 532.66±40.98 & 518.50± 37.72 w, respectively. Also, between anthropometric indices, standing height, weight, length of the lower limb, wrist diameter, elbow and knee diameter with anaerobic power and standing height and diameter of the ankle significant relationship was observed with aerobic power (P≤0.05). Therefore, it seems that indicators such as: tall stature, low body mass index, high VO2MAX and anaerobic power could be important for Football referees’ talent identification and to determine inclusion criteria in regard to elite referees’ selection.

The aim of this study was to examine the effects of a BCAA supplementation on markers of muscle damage followed eccentric exercise in basketball players. Twenty-six elite male basketball players (mean ±SD age, 29.04±3.55 years; weight, 89.54±8.98 kg; BMI, 25.43±1.44 kg.m2; body fat percentage, 14.30±3.60) volunteered to participate in the study and were selected randomly and assigned to supplement (n=13) and placebo (n=13) groups. The damaging exercise consisted eccentric exercise (15 set and 10 repetitions per set). Creatine kinase (CK), lactate dehydrogenase) LDH), maximal voluntary contraction (MVC), muscle soreness was measured immediately before the damaging exercise and at 24, 48, 72 and 96 hours’ post-exercise. Data were statistically analyzed using SPSS 18 (P<0.05). There was significant reduction in CK, LDH and muscle soreness in the BCAA group compared to the controls (P<0.05). In addition, the recovery of MVC was greater in the supplement group (P<0.05). BCAA supplement decreases eccentric exercise induced muscle damage and improves recovery in male basketball players.

In this study, we investigate the effect of treadmill running with consumption of 1.25 dihydroxyvitamin D3 on NGF levels in Parkinsonian rats’ striatum induced by 6-hydroxy-dopamine. 48 rats (weight 276± 10g and age 12 week) were divided into 6 groups: control, sham، control Parkinson, exercise + Parkinson, vitamin D3 + Parkinson, vitamin D3 + exercise + Parkinson. Exercise group: five days per week for 4 weeks during the light cycle. Rats were run twice per day at a speed of 15 m/min separated by at least 1 hr; each running bout lasted 15 min for a total of 30 min per day. Parkinson supplement group in during study period received 1 µg/ml/kg VD3 intraperitoneally Two times per week. To induce Parkinson, 250 mg/kg in volume 5m/l of 6-hydroxydopamine (6-OHDA) was administered into striatum by a stereotaxic apparatus. NGF level in the striatum were measured by ELISA. Alone-intensity exercise the protocol presented in this study, nerve growth factor levels Increased but not significant(P=0.372). On the other, the supplementation VD3 alone levels of nerve growth factor (P=0.002) to increase significantly، also combining it with exercise could NGF levels (P=0.0001) shows a significant increase. Our findings show that pre-treatment with treadmill running and consumption supplement of 1.25 dihydroxyvitamin D3 have a protective role against 6-OHDA induced toxicity.

The purpose of the present study was to examine the effect of 8 weeks of Combined (resistance and Proprioceptive neuromuscular facilitation) training on Muscular performance and Functioning, and the degree of disability of patients suffering from multiple sclerosis. To this end, thirty-seven male and female subjects with Multiple Sclerosis were randomly- purposefully assigned to the experimental (n=19, age=34.53±6.51, Weight=67.02±13.14, EDSS=2.55±1.21) and control (n=18, age=36.78±4.93, Weight=66.92±10.13, EDSS=2.88±0.97) groups. The experimental group received a combined (resistance and Proprioceptive neuromuscular facilitation) training program for 8 weeks. In the experimental group, the Muscular performance and Functioning, and the degree of disability of the subjects were evaluated before and after the training protocol. The obtained Data were analyzed using independent T-test and paired sample T-test. The Results showed that 8 weeks of Combined training caused a significant increase in lower body strength (P=0.001), upper body strength (P=0.001), Dynamic balance (P=0.001), flexibility (P=0.001), gait speed and endurance (P=0.001) factors. But there was seen no statistically significant gain in the degree of disability factor (P=0.32). Therefore, a period of 8 weeks of Combined training (resistance and PNF) caused a significant increase of strength, balance and speed and distance of walking, without lowering the degree of disability factor. Therefore, it is suggested that this type of training be considered as part of the intervention in the rehabilitation program and improvement of patients.

The aim of this study was to determine the correlation of vital capacity of 11 to 17-year-old girl students measured by spirometry and allometry equation. For this purpose, a number of 311 girl students with average of age 14±3 years and average of weight 48/83±9 Kg and average of height 153±76 cm were selected and their vital capacity were calculated by spirometer and also through allometric equation. Then, the statistical method of Piersson's Correlation coefficient was used to assess the correlation between two method of measurement of vital capacity. The statistical method of t test in independent groups was used to assess the difference between vital capacity’s mean of athlete group and non-athlete. the analysis of the data showed that allometric equation enjoys high validity in determining the vital capacity of 11 to 17 years old girl students. (r=0.83 and α=0.86). and there is not difference between vital capacity’s mean of athlete group and non-athlete. There for the result of this research shows that allometric equation can be used for determining the vital capacity of girl students in the conditions when exercise laboratory and spirometer are not available.

This study designed to investigate the influence of length of curcumin supplementation on antioxidant capacity of adolescent taekwondo players at ephemeral taekwondo tournament. For this purpose, 30 adolescent taekwondo players (age: 15.13±2.96 yrs, height: 173.17±7.29 cm and weight: 59.82±10.83 kg) were assigned randomly to three groups: middle term group, n=10), short term group, n=10) and Placebo, n=10). Middle term group received curcumin 48 hrs before tournament until tournament opens start and short term group received curcumin (totally 140 and 70 mg respectively) between competitions (10 minute competitions, 3 times with 1-hour interval). Placebo group received placebo during 48 hrs before and between competitions. One hour following last competition, blood samples were collected and used for determination of antioxidant enzymes including GPX and CAT enzymes activity and MDA level. ANOWA results showed that GPX activity (U/mg pro) in Middle term group was increased significantly (P=0.0001); Whereas, CAT activity (U/mg pro) were not significant differences (P=0.098). Also, there was no significant differences in MDA level (Nmol/ml) between all 3 groups (P=0.437) but, it was insignificantly lower in mid-term in compare to short-term and lower in this both groups in compare with placebo. These findings suggested that curcumin consumption 48 hrs before short term competitions may be affects antioxidant enzymes concentration and promotes antioxidant capacity of adolescent athletes during heavy competitions. This strategy can accelerate recovery from repeated stresses during ephemeral tournament.

The aim of this study was to investigate the effect of long-term L-carnitine supplementation and endurance training on the blood lipid profile and plasma levels of lipoprotein lipase. In this semi experimental study, 20 non-athlete students randomly divided into two groups of supplementation (n = 10, mean age 20.1±0.9 years, weight 74.2±2.5 kg, height 176.1±4.8cm) and placebo (n = 10, mean age 20.1±0.6 years, weight 67.7±4.6 kg, height 177.7±4.6cm), respectively. HDL, total cholesterol (TC), LDL, VLDL, lipoprotein lipase, RF and body fat percentage evaluated for a period of six weeks and 3 days a week. of training according to the principle of overload. The intensity training 65-75% Maximum heart rate each subjects. During this period the group supplementation used 13mg of L-Carnitine per each kilogram of body weight and the group placebo used just 3 mg of starch per each kilogram of their body weight. The two groups were studied before and after training for TG, TC, HDL, LDL, VLDL, RF as well as lipoprotein lipase. The data analyzed using SPSS-20 and independent and dependent T student test. Our findings showed a significant increase in HDL (P<0.05) and decrease in TC, body fat percentage of the group supplementation (P<0.05), but considering the BMI and the amount of TG, LDL, VLDL, RF and lipoprotein lipase there was no significant change observed. Based on the finding of this study, we can say that if young people use L-Carnitine besides their aerobic training this may increase their HDL and decrease TC, and body fat. But for the effects on lipid parameters and lipoprotein lipase in L-Carnitine use besides aerobic training we need more research.
