Research in Sport Medicine and Technology

Abstract
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.

Background and aims:
In many communities, the sport as a method of therapy is used to improve the
disabled and veterans' health which has been a useful and effective. The aim of
this study was to examine the effect of aerobic exercise on general health and
serotonin levels in inactive veterans. Material and method: Based on semi
experimental design 40 veterans, 25 percent impaired and with age average
40/3±1/4, were selected and randomly divided into two experimental and control
groups. Subjects in the experimental group participated in a period of 12 week’s
aerobic exercise training program, which done 3 times a week at 50-65 percent
of Vo2max. Control group did not participate in any exercise program during
study period. General health of the subjects and its subscales was measured by
the General Health Questionnaire (GHQ). Serotonin levels, VO2max, percent
body fat and BMI before and after training for both groups were measured
respectively. Data were analyzed using t-tests at 5% alpha error level was
performed using SPSS version 16. Results: Data analysis showed significant
difference between the two groups in general health. The difference in
psychosomatic subscales, anxiety and insomnia, social dysfunction and
depression were observed between two groups. Also, the results of this study
showed that after 12 weeks aerobic exercise, percent body fat, BMI and lipid
profile decreased significantly in training group. VO2max and serotonin also
increased significantly compared with the control group (p<0.05). Conclusion:
Aerobic exercise for inactive veterans maybe effective in reducing serotonin
levels and increasing general health and placed in line health promotion
programs.

Overweight is one of the most important reasons for increasing the liver enzymes that causes liver and cardiovascular disease. The purpose of this research is to investigation the effects of 12weeks training on liver enzymes. Subjects of this research is 26 woman with BMI≥29 and average age Between 42 to 52, they divided to two main groups: experimental and control group n=13. 24 hours before training and 48 hours after sampling, body composition and oxygen maximum, were done for all of the subjects. Experimental group have done 12 weeks endurance training that contains 3 session between 40 to 80 percent of heart beat and duration of 15 to 30 min. Data was analyzed by using of covariance and T test,(a≤0./05),results showed that in experimental group there is significant increase in oxygen maximum (p=0/006) and significant decrease observed in BMI (p=0/001). But not observed significant change in ALT enzymes (p=0/493) and AST (p=0/403). Results showed that the impacts of 12 weeks endurance training on liver enzymes of those women was not significant because of not preparing of subjects, also high level of BMI in both groups are possible. Therefore, non significant increase of ALT exercise group be investigated, the longer half life of this enzyme is (40+12) hours. So, it seems that we need more than 48hours to recovery the enzyme.
