The Effect of Continuous and Intermittent Training on Ghrelin
Hormone in Non-Athlete Obese Women
M. Kamyabnia , Sh. Soheily, E. Yadegari Hematabadi
Abstract
The aim of this study was to describe the effect of continuous and intermittent
training on ghrelin hormone in non-athlete obese women. For this purpose, 30
obese female students (BMI ≥ 26) who volunteered to participate in this study
were selected and randomly assigned to three groups (continuous training, intermittent training and control). The experimental training groups performed
training three days a week for 12 weeks at a definite intensity and distance.
Before and after 12 weeks of training, ghrelin (Elisa protocol), weight, BF%,
BMI and Vo2max were measured. Data were analyzed by one-way analysis
of variance. Results showed that continuous and intermittent training had a
significant effect on ghrelin, body weight, BF%, BMI and Vo2max (P≤0.05 ).
There was no significant difference between the two types of training. It seems
that physical training (continuous and intermittent) significantly increases the
levels of plasma ghrelin.

An Investigation of Abilities and Importance of Computer Skills
in Iran Sport Organizations
S. Mohammadi, N. Esmaili, N. Salehi
Abstract
Sport managers can complete their tasks and projects more efficiently than
before using computers and related software. As a result, it seems necessary
for sport managers to gain fundamental computer abilities which can help to
promote organizational goals. Therefore, in order to investigate the abilities
and importance of computer skills in Iranian sport organizations, 137 managers
were selected as the sample and responded to a researcher-designed questionnaire with proper face and content validity (panel of experts), construct validity
(exploratory and confirmatory factor analysis) and reliability (alpha Cronbach).
Descriptive and inferential statistics (ANOVA, MANOVA) were used for data
analysis. Results showed a significant difference between the rate of abilities
and importance of computer skills in Physical Education Organization, sport
federations and the General Office of Schools Physical Education. Also, the
results of MANOVA showed a significant difference among the subscales of
the importance of computer skills in completing sport management tasks and
projects. Overall, it can be noted that because of the extensive nature of sport
section, diversity of activities and early changes in data, managers are required
to use computer skills with their most abilities so that organizational processes
can be performed with more speed and accuracy and less expenditure.

The Effect of 12 Weeks of Combination Training Program on
Serum Leptin, C-Reactive Protein (CRP) and Insulin Resistance
Index (HOMA-IR) in Overweight Men
R. Abbasi Bakhtiari, B. Abedi
Abstract
The aim of this study was to examine the effect of 12 weeks of combination
training (CT) program on serum leptin, C-reactive protein (CRP) and insulin
resistance index (HOMA-IR) in overweight men. In this quasi–experimental
study, 30 sedentary men (age 20.97±1.9 years, BMI 26.47±0.75 kg/m-2) were
randomly divided into the experimental group (EG: n=20) and the control
group (CG: n=10). The EG performed CT which included aerobic exercise:
60%-70% of their VO2max for 20 min. and resistance exercise: 2 sets of 10
repetitions at 70% of 1 repetition maximum. The CG did not perform any
physical exercises. At the end of the end of the CT, blood samples were collected from the EG. Leptin, CRP and insulin resistance index were measured
before and 12 weeks after the training. Descriptive statistics were used and for
the inferential analysis, paired t test was conducted. At the end of the 12th week,
there were a significant reduction in serum CRP (1.45±0.27 mg. l-1 versus
1.39±0.3 mg. l-1, P<0.05), leptin (7.27±0.68 ng.ml-1 versus 7.24±0.65 ng.ml-1,
P<0.05) and insulin resistance index (1.6±0.14 versus 1.5±0.23, P<0.05). It
was concluded that 12 weeks of combination training could decrease leptin,
CRP and insulin resistance index in overweight men, and this improvement
was accompanied with increased cardiorespiratory fitness and decreased body
fat which was independent of measurable changes in weight and BMI.

The Effect of Isometric Contraction in Lactic Acid Production on
an Active Limb and Its Effect on Lactic Acid of an Inactive Limb
M. Kasb Parast, H. Tabatabaei, A. Memari, P. Zarei, R. Abdi
Abstract
The aim of this study was to investigate the effect of isometric muscle contraction in generating lactic acid on an active limb and its effect on the amount of lactic acid of an inactive limb. 12 non-athlete
male students from Islamic Azad University (Tehran South branch)
who aged between 20 and 22 (21.8 ± 4.12) and did not have regular
sport training over the past two years participated in this study. Firstly,
the amount of lactic acid was measured in active and inactive hands at
rest before the protocol. Subjects participated in an advisory session
where procedures were explained and they were prepared to perform
the protocol in the next session. Before the protocol, lactic acid was
measured at rest to assure that the subjects did not have any physical
activity. Then, the subjects performed isometric contraction until exhaustion. Isometric contraction was performed: a weight equal to 70%
of maximum strength of elbow flexors was selected for every subject.
Then, they held the weights at an angle of 90̊ of elbow and upper arm
until exhaustion for 45 seconds. This 2-minute procedure was repeated
with 15-second rests. Immediately after the aforesaid procedure, the
amount of lactic acid of active and inactive limbs was measured. The
data were analyzed using dependent t test and the results showed that
after isometric contraction, lactic acid was accumulated in the active
muscles (α=0.01). With regard to the measurement of lactic acid in the

inactive limb immediately after the training, the results indicated that
the transfer of lactate in the blood to the inactive limb was not to such
an extent that it could affect the limb (α=0.01). On the other hand, the
subjects did not report fatigue in their inactive limb after the isometric
training which approved the present results. The results of this study
did not approve the effects of accumulated lactic acid in the active limb
and its transfer to the inactive limb and they were inconsistent with the
theory of transfer of power and muscular endurance from trained limb
to untrained limb (cross transfer theory).

A Comparison of Two Methods of Selected Strength and Flexibility Training on Shooting Range and Dribbling Speed in Soccer
Players of Tehran Premier League
M. Chaleh Chaleh, Sh. Nazari, H. Sedghi, A. Shakibirad
Abstract
The aim of this study was to compare two methods of selected strength
and flexibility training on shooting range and dribbling speed in soccer
players of Tehran premier league. 30 soccer players of soccer premier
league teams in Tehran city (mean age 21.73+2.87 yr, height 178.33+5.39
cm and weight 72.86+5.75 kg) who were preparing themselves to
participate in the competitions of 2010-2011 season volunteered to
participate in the study. Subjects were randomly divided into strength
(n=15) and flexibility (n=15) training groups. First, all subjects were
informed about the purpose, requirements and the experimental protocols
of the investigation. Afterwards, dribbling speed and shooting range tests
were conducted to measure these variables. After 8 weeks of strength and
flexibility training, the tests were performed again. Data were analyzed
by paired and independent t-student tests. Results showed that the
selected strength training had a significant effect on the shooting range
and dribbling speed of the soccer players (P=0.000). This was true for the
selected flexibility training as well (P=0.000). Also, there was a significant
difference between the effects of the two methods on the shooting range
of the soccer players (P=0.008) and on the dribbling speed of the soccer
players (P=0.001). According to the results, it can be concluded that both
strength and flexibility training improve shooting range and dribbling
speed and they can be suggested to the soccer players. In addition, strength
