In this study, the effects of vibration training on physical fitness factors in elderly
females investigated. 40 subjects with age 61/09±6/24 yrs, weight 65/84±11/98
kg, height 156/99±5/06 cm and body mass index 26/64±4/23 kg/m2 voluntary
participated in this study and were divided in vibration (n=16), non-vibration
(n=14) and control (n=10) groups. The vibration group performed exercises on
the device (JET VIB) for 10 days with 35-40Hz frequency, 12 mm amplitude and
eight positions. The non-vibration group performed the same exercises (in
position, set and time) on the turned off device. The control group did not
exercise during the study. Leg and hand strength (dynamometer), flexibility (sit
and reach), balance (standing time on one leg) and body composition (skinfold
with caliper) were measured. Paired sample t test and one way ANOVA used
for data analysis. In within group analysis, vibration group showed significant
increase in right (p=0/02) and left hand strength (p=0/01), leg strength
(p=0/008), Flexibility (p=0/005) and left leg balance (p=0/006). In non vibration
group just significant increase in right hand strength (p=0/01). There was no
significant change in control group. Between group analysis showed, significant
increase in right (p=0/006) and left hand strength (p=0/003), leg strength
(p=0/004) and left leg balance (p=0/01) in vibration group comparison with to
other groups. There was no significant change in right leg balance (p=0/),
Flexibility (p=0/005) and body composition in any of groups. Due to the results
short term vibration training can improve flexibility, strength and balance in
elderly subjects.

The purpose of this study was to investigate the relationship between success
on an over 6000m summit and results of physical fitness tests that normally are
performed by mountaineering federation to select mountaineers for climbing
high mountains. Therefore in this study, relationship between the results of
these tests in 8 female climbers (age, 34.4±8.7year, height, 163.9±5.9cm, body
mass, 60.6±3.8kg) and their performance and success while ascending Mera
Peak (6654m) were assessed. Results showed that none of the cooper test,
long jump, chin up, and sit up tests; and also weekly training volume, age, body
mass, BMI, and percent of body fat were significantly correlated to climbing
ability at altitude, summiting, or incidence of acute mountain sickness.
Summiting was only related to climbing ability over 5000m in 2 days before
summiting (p=0.039) and sleeping history over 3000m (p=0.002). In conclusion,
physical fitness near to sea level could not guaranty climbing ability, summiting,
and healthy mood at high altitude. Climbing and sleeping history at high altitude
may be better criteria for a successful upcoming climb.

Aim: The aim of this study was to determine the effect of basketball specific and general training on physical and physiological fitness in male basketball players trained. Methodology: The statistical population of this research was 18 basketball players trained invited to Asad Abad preparation camp. 12 players out of the total number participated in this study were ranked by fitness level and randomly assigned to a specific (N=6) and general training groups (N=6). Each player completed a special questionnaire to be healthy during the study period. The specific and general training groups have performed the trainings in interval model three sessions per week for 6 weeks; each session was 40 minutes. Results: Cohen’s effect coefficient percent and independent samples t-test were used to analyze the data collected in pre-test and post-test. Significant differences were shown in aerobic power, feet explosive power, fatigue index, fatigue percentage, maximum anaerobic power, mean anaerobic power, and running sprint (P≤0/05). There were no significant differences in maximum running sprint; total time repeated running sprint ability, minimum anaerobic power, agility, and distance running (P≤0/05). Conclusion: The results of this study have suggested that the basketball movement specific training circuit should be used to improve aerobic power, fatigue index, and fatigue percentage. Also, classical training has suggested in order improving feet explosive power, maximum anaerobic power, means anaerobic power, and running sprint.

Introduction: Whole Body Vibration (WBV) as a new method and supplement for neuromuscular training, cause mechanical stimulation in this system. Propose: The aim of present study was to determine the effect of Whole Body Vibration training (WBVT) on some factors of the physical fitness, growth hormone and IGF-1 concentration in trained girl students. Materials and methods: twenty female of physical education students with a mean and standard deviation of age (21.75 ± 2.2 Yr.), weight (54.25 ± 7.28 kg) and BMI (20.1± 2.44 kg/m2) were selected and randomly divided into two groups: experimental (n=10) and control (n=10). WBVT for 10 days with frequencies 30 Hz and amplitude of 10 mm in six different body positions were performed. Blood samples were collected 24 hours before and after WBVT. Data were analyzed by dependent t test and paired t test. Results: The statistical analysis showed, WBVT lead to significant increase of strength, speed, power, growth hormone and IGF-1 concentrations in experimental group (P<0.05), while agility in this group was not significantly changed (P>0.05). Conclusion: WBV training program can be used as modern training methods and supplements along with other training methods to improve the levels of anabolic hormones and physical fitness factors.

The aim of present study was comparison of advanced physical fitness profile between Olympic soccer team members of Iran according to playing position. 29 Invited soccer players to the 17th national Olympic soccer team of Iran dispatched to 17th Asian Olympics Games, Incheon 2014 )mean age of 20.39± 2.01 yrs(, divided into five group of goalkeepers, defenders, midfield players, wingers and attackers according to playing position participated in the study. Body composition parameters (including body mass index, body fat percentage), isokinetic force (peak torque, agonist/antagonist ratio, work fatigue, total work of extension and flexion), aerobic power by analysis of respiratory gases and anaerobic power and fatigue index by Wingate test were packaged for data collection. Descriptive statistics (i.e., mean ± standard deviation) and inferential statistics (i.e., one way ANOVA with Hopkins post hoc after subtracting data  of pre- post) used for analysis data. While it was unbelievable the findings did not show any significant difference between five groups of present study. It seems that Olympic soccer team players of Iran has not prepared in a conditioning principle and based on playing position for participate in 17th Asian games. Moreover it supposed that national players spent most of the preparation periods & specific based conditioning workouts on their clubs, hence due to the short time of conditioning in the national camps trainings, players have not dispatched to the games with favorable preparation.
