The main goal of this research was to detennine effects of a submaxiamal aerobic exercise on rate of changes of ferritin, iron and TIBC blood plasma in
young patients with Talassemia Major. Standard Balke test was used on a treadmil that consisted of 25 stages and in order to be aware of risks involved during exercise, electrocardiogram leads were placed on subjects. Blood samples
were collected and analyzed in three stages, before, immediately after and 36 hours after test. Ten patients with Thalassemia Major were selected randomly and tested. Data were analyzed using statistical methods such as paired T- Test and Multi-regression. The results indicate: 1) the amount of ferritin decreased significantly during exercise compared with rest stage. 2) The amount of ferritin
in recovery period increased compared with exercise stage. 3) Iron and TIBC were not changed in either exercise or rest stage. 4) There was a positive correlation between ferritin, iron and TIBC recovery (r = 0.74). 5) Ferritin decreased below 65% HR.R, but increased above this level.

The propose of this study was to collect descriptions using the Deify Method and appoint the degree of criteria importance from subjects in the field of free-style and Greco-Roman Wrestling. Subjects in this study were coaches (20) and Wrestlers (30) of national teams. The Dlfy Method classifies national coaches selection criteria in 8 dimensions.’ social, athletic, characteristic-Perceptual, scientific - speciality, Personal, Management skills, Sentimental-human and business antecedent of Speciality. Each of these Dimension had numerous subgroups. The degree of importance of fundamental dimensions was specified with researcher-prepared questionnaire. Importance conclusions of this study were as follows . Between coaches and wrestlers there was a significant difference in grading of coaching dimension. Grading of coaching dimension by all subjects was as follows .‘ characteristic - perceptual, specially , social, speciaty, sentimental - Human skills, management skills, scientific - specialty, athletic specialty, business antecedent of specialty and individual specialty.

The aim of this study was to evaluate the effects of a selected plyometric training program on the functional and structural changes in the heart after explosive exercise which is combined with a regular program in soccer. Thirty male college students, who voluntarily participated in this study, were randomly divided into experimental and control groups. The training program consisted of a selected plyometric exercise 3 days/week for 12 weeks. Some heart
characteristics were obtained and measured by using a non-invasive echocadiogram (one, two, dimensions). A significant increase was observed in the interseptal wall diameter (IVSS, and IVSD) and the posterior wall thickness
of the left ventricle of in systole and diastole (PWS and FWD) (P< O. 05,

The purpose of this investigation was to study the effects of and compare two interval weight training programs with two different recovery times (Long-term and short-term) on some muscular functions (anaerobic power, force, strength and endurance) in high school students of Esfahan who were randomly assigned
to either long-term or short-term interval weight training group, respectively.
Before and after 12 weeks of training, the subjects were tested by a series of
specific experiments. The subjects in each groups carried out the same special
interval weight-training program (Delorm-Watkins method), three times a week for 12 weeks. However, the recovery periods between sets of training were
different. Group 1 and Group 2 experienced 160 second and 40 seconds rest
between sets of training respectively. The pretest post-test difference analyses for
dependent variables indicated significant improvement in muscular force and
anaerobic power of legs and muscular force of dominant leg in Group 1 (long rest) (P

45 subjects, pulmonary patients who are victims of chemical warfare, were selected during the period of 2000-2001 for study. By applying the spirometeric indices including force expiratory volume first (FEV1) and forced vital capacity
(FVC), physical tolerance of the subjects to activity though six minute walking test changes were measured and tested. The subjects were placed in three groups:
1. Swimming group 2. Running group 3. control group Each group consisted of 15 subjects (Chemical warfare injured) who proved to be qualified for the research. Each group undertook specific swimming and running exercises
independently. statistical methods applied includ " data analysis, descriptive statistics, T Test and variance analysis of multiple variables. By applying the principle of overload, the swimming and running groups were made to do the
exercises at the highest degree. The results, based on P < 0.001, shows there was
is a significant difference in the FEV1 of the lungs swimming and running groups. Concerning physical tolerance to exercises, there is also a significant difference between the two groups (running and swimming) on the one side, and the control group on the other side.

The purpose of this study was to determine the effects of eight weeks of aerobic and anaerobic training on a number of cardiovascular risk factors of
male students at Shahid Chamran University. Study groups consisted of 36 volunteers aged 20-30 years from different colleges, who were randomly divided in control, aerobic and anaerobic groups.
Cardiovascular risk factors such as C- T, HDL-C, LDL-C, VLDL-C, TG,
RF, BMI, fat percent, BPI and BPz were measured in all! samples during
pre-test. Then, the aerobic and anaerobic groups took part in 8 weeks predetermined physical programs, while the members of the control group were asked not to take part in any kind of physical training programs during this period. All of the samples used regular university's self-service food program. After 8 weeks, research varia bless were again measured as post-test. Descriptive statistic, M40VA, and Tucky test at the significant level of P _ 0105 were used to test the hypotheses. The findings were as follows..
There was a significant reduction in C- T of both aerobic and anaerobic groups (P=O.OOl), but there was no significant difference between aerobic and anaerobic groups. The amount of HDL-C was significantly increased in aerobic
and anaerobic groups. The amount of VLDL-C, LDL, C and TG had not significantly changed after 8 weeks of training. Although, this level in aerobic and anaerobic groups (special in aerobic group) were reduced, not the finding was non-significant. There was significant reduction in RF of both aerobic and anaerobic groups (P
