The purpose of the present study was to survey the effect of Neurobion supplement with exhaustive exercise of boxing on Lactic Acid, LDH, CK and CRP in amateur male boxers. 12 amateur male boxers with mean age of 19.14±2:02 years,71.35 ±6.25 weight and body fat percent 8.81± 0.65were randomly assigned to two groups of experimental and control in crossover experimental design and they consumed supplement and placebo for two consecutive weeks amount one 5cc Ampoule. The subjects performed exhaustive exercise of boxing included impact punches to boxing bag in 3 rounds with 1 minute rest between each rounds with intensity of 80-90% of MHR with polar heart measure (made of Finland) in two consecutive weeks. The investigation has done in two phases that one phase was supplement condition and placebo condition was another’s. The subject’s blood samples were collected in 4 times pretest, immediately, 2 and 6 hours after exercise for measuring lactic acid, LDH, CK and CRP levels. The results of factorial analysis showed that levels of Lactic Acid, LDH, CK and CRP were significantly lower in supplement condition compare placebo condition. Generally, consuming (B1, B6 and B12) has special affected on metabolism and enzymatic process during metabolic process and it would decrease fatigue indexes cell damage factors after an exhaustive exercise.

A and B apolipoproteines plays an important role in transport of cholesterol and incidence of cardiovascular diseases, particularly atherosclerosis. The purpose of this study was to evaluate the impact of a severe bout of aerobic exercise on plasma levels of apolipoprotein A, B and blood lipid profiles in non-athlete females. In this semi-experimental study, 20 female volunteered and randomly assigned into training (n=10) and control (n=10) groups. The exercise protocol was 1.5 miles cooper aerobic endurance test. Fasting blood samples were taken before and after exercise to assess the variables (for control group only one step). Data were analyzed using t-test. The results revealed that after exercise, the amounts of Apo-A, HDL and TG were significantly increased, but the declines of Apo-B, LDL and TC and were not significant (p>0.05). It can be concluded that even a single bout of aerobic exercise performed with high intensity lasting can lead to a positive effects on some cardiovascular risk factors such as HDL-C and Apo-A.

Caffeine is one of the most widely used material in the world is, although little nutritional value but as an ergogenic allowed to have attracted the attention of many competitive athletes. The purpose of this study was to investigate the effect of caffeine consumption on muscle strength and endurance in elite middle distance runners. For sampling due to the small population of targeted and available methods were used, the total population of the 14 runners with an average age of 23.32 ± 0.04 years, height of 178.17 ± 1/12 cm, weight of 65.62 ± 1.11 kg and VO2 max 62.32 ± 2.44 ml/kg/min Which has a history of winning competitions in provincial and national championships were attending. To participate in the research and double blind study and randomly divided to two groups: Supplement and placebo. The Supplement group, received 6 mg/kg caffeine and placebo (rice flour). In tests session, the muscle strength and endurance were evaluated with one-repetition maximum and 70% 1RM repetitions tests in Leg press and bench press respectively. Independent t-test was used Showed that the average strength and muscular endurance in the Supplement group was significantly increased compared to placebo. Statistical analysis showed that there was significant increase in strength and endurance in the caffeine group; (P˂0.05). While there were no significant changes in placebo group. Based on these findings, it can be concluded that consumption of 6 mg/kg caffeine significantly improved muscular strength and endurance in the elite middle distance runners.

Nowadays, coaches were concerned to the plyometric as an effective way to strengthen the functions in fast and explosive athletes The aim of the present study, compared the effects of six weeks of plyometric training on anaerobic power of the lower extremities is the taekwondo and fencing Players. The statistical population this quasi-experimental study are taekwondo and fencing girls in Tabriz in 2013 years, of which 7 taekwondo and 7 fencer were selected by available sampling and were divided into two experimental groups. Both group for six weeks (three days per week) did plyometric exercises. For the analyze data used from the Kolmogorov-Smirnov test for normality of data and the correlated two-way ANOVA test to examine the assumptions. The statistical results showed that plyometric training significantly increase the explosive power of lower extremity. There is no significant difference between taekwondo and fencing in effect of plyometric training on anaerobic power. It is concluded that plyometric exercises as a method of low-cost training, accomplished and fruitful along with other training methods can be used.

strength is considered as an important index for athlete's progression and the type of resistive exercise hasan importantrole in developing it, The aim of this study was to evaluate the effect of eight weeks of isotonic and isokinetic training on maximal voluntary isometric torque (MVIT) of knee extensor muscles. 24 active men randomly divided intothree groupsincluding: isotonic, isokinetic, and control groups. MVIT of knee joint or maximal voluntary isometric knee extensor torque in experimental and control groups were measured before and after eight weeksconcentric exercise training; Dependent t-testand one-way-ANOVA were used for data analysis (α=0.05). The results indicated that mean MVIT increased significantly in both isotonic and isokinetic groups; whereas there was no significant difference between two groups. According to the results, it seems that both isotonic and isokinetic training will improve static strength, but there is no difference between the effects of these two methods on strength improvement.

Fat tissue is secretion hormones such as chemerin and Omentin. Adipokine of the Omentin that is Contains 313 amino acids thatsecreted most of visceral adipose tissue and there is two wayomentin- 1 and omentin-2. However omentin 1, is the most common form of human blood circulation.The aim of present study was to investigateEffect of the Comparison 12 weeks aerobic andResistance exercise on levels of Omentin-1 plasma and Blood pressure in hypertensive elderly women. In this study, 45 hypertensive elderly women were chosen and Selectively divided in to three groups, control (n=15; Age: 56.2 ±9.8; Systolic blood pressure 131 ±0.87; Diastolic blood pressure 78.9±0.56) and the rest were divided into two groups experiment (n=30; Age: 55.10 ± 6.08; Systolic blood pressure 132.8 ± 1.36; Diastolic blood pressure 77.6 ± 0.78). The training program included aerobic, Resistance exercises which were conducted increasingly, 3 times a week for 12 weeks. Blood samples and measure the blood pressure of participants were taken before starting the exercise training and also24 hours after the last training session. Data were evaluated using analysis of variance and Tukey test at a significance level p≤0.05 was done. Found then 12 weeks of exercise it does not occurs significant differences in the levels of omentinand diastolic blood pressure in Group training and alsosignificant differencesin systolic blood pressurein the group resistance. But itdoes occurs significant changes in systolic blood pressure in thegroup aerobic. 12-week aerobic exercise, Resistance, have not been able to arrange causes increase omentin and decrease in and diastolic blood pressure But 12 weeks of aerobic exercise has been able reduced systolic blood pressure in the subjects.

For many years gradualtapering was done. New theories with an emphasis on two-stage tapering Suggest that the load of training reduced gradually and then a few days before the race, the load of training rise again. Therefore the aim of this research is Study the effect of two-stage tapering in compare with gradualtapering on serum lactate, testosterone and cortisol in male swimmers. In this semi-experimental study 12 young male swimmers (with age ranging from 14 to 17 years) as available sampling were selected. Subjects based on their final record were divided in to two groups: two-stage tapering group (N = 6) gradualtapering group (N=6). Before and after the completion of 2 weeks tapering Program, performance test and blood samples were taken for assessment serum levels of lactate, testosterone and cortisol. To evaluate the result paired T-test and ANCOVA (analysis of Covariance) were used. after 2 weeks of tapering program, in two-stage tapering group compared with pre-test, serum levels of lactate and cortisol was increased significantly (P>%5). But in gradualtapering group compared with pre-test, serum levels of cortisol was increased significantly (P> %5). changes in serum lactate and testosterone levels in two-stage tapering group compared with gradualtapering group was not significant (P> %5). While increase in serum cortisol levels in two-stage tapering group compared with gradualtapering group was significant (P> %5). Generally it can be said, that likely two-stage tapering strategies compare then gradualtapering strategies have more catabolic effect.

The aim of current study was to evaluate the effect of 8 weeks aerobic training and 2 weeks detraining on Vascular and Cellular Adhesion Molecules in Middle aged women. The study population of women employees Shiraz University of Medical Sciences were referred to the University Sports Club, among them, 24 people were volunteers selected as sample And randomly divided into experimental and control groups.Trainings consisted of eight weeks of aerobic exercise, three times per week, to run of 55 to 65% of maximum heart rate and then; had detraining for two weeks. Venous blood samples were collected in the first week, the eighth week and the tenth week. To analyze the data we used of Kolmogorov-Smirnov test, analysis of variance with repeated measurements. Results showed that 8 weeks aerobic training and two weeks of detraining had no significant effect on vascular and intracellular adhesion molecules in middle-aged women. Therefore, it can be concluded that the exercise protocol and the period of detraining cannot favorable impact on intercellular adhesion molecules and vascular on middle-aged women.
