The purpose of this study is to research the knowledge of pregnant women towards sport activities using data mining algorithms. Statistical population includes all healthy pregnant women referring to health centers in Gorgan city (Iran) in 2014 from which 429 were chosen as the sample using cluster random sampling. The questionnaire included 65 questions in 6 sections each relating to one knowledge level. Data related to each knowledge level were categorized by decision tree algorithms (CHAID, CART C5.0, QUEST) to predict general knowledge with 3 knowledge descriptions (good, medium, poor) and 5 knowledge descriptions (very good, good, medium, poor, very poor) and then were compared. Also the relationship of these knowledge levels was compared using regression algorithms and SVM. Results show that most of the population has a good and medium knowledge and their knowledge about sport during pregnancy is suitable. In predicting the level of knowledge using decision tree in both prediction level (5 label and 3 label), C5.0 algorithm had the most accurate prediction. Also in comparison, SVM algorithm and SVM regression algorithm had better results with the least error. As a result, it can be said that Extracted rules from algorithms helps to estimating the level of knowledge faster than traditional statically way and provide education regarding exercises during pregnancy for the health of mother and fetus.
Background. The aim of this study was to assess the health-related behaviour of women practising judo and ju-jitsu in comparison with others (active and physically inactive).
Material and methods. The study involved 414 women aged 18 to 30. For comparison purposes, they were divided into three groups. Group 1 (n=56) were women practising judo or ju-jitsu. Group 2 (n=166) were persons practising other types of regular physical activity and Group 3 (n=192) included those who did not engage in organized physical activity of any kind. The study used the Juczynski Health-Related Behaviours Inventory and the authors’ own survey.
Results. The studied judo and ju-jitsu athletes were characterized by a high or average level of health behaviours (on average 85.87). The total score of the intensity of health behaviours achieved by amateur athletes practising combat sports and martial arts was higher than the results of the other groups (p<0.01).
Conclusion. Women practising martial arts were characterized by a high overall index of health behaviours – they more often paid attention to correct eating habits and preventive health behaviours, among others. This may testify to the intellectualization of athletic and health-related training and the transfer of desired behaviours to everyday life.
Background and Objectives: Nonalcoholic fatty liver disease is the most common chronic liver disorder and is also currently considered as the hepatic manifestation of metabolic syndrome. Regular exercise training may decrease fatty liver disease complications, although its impact is not yet clear. This study aimed to evaluate the effects of six weeks of aerobic training on liver enzymes and other factors contributing to metabolic syndrome in young inactive women. Methods: In this quasi-experimental study, 37 inactive overweight women were randomly divided into an experimental and a control group. The experimental one participated in a controlled aerobic training program (5-minute interval walking) at 65-90% maximum heart rate for 6 weeks, 45-90 minutes per session and 4 sessions per week. Blood samples were taken following 12 hours of fasting, both before and after the training program. Results: The levels of aspartate aminotransferase and alkaline phosphatase decreased in both groups. Alanine aminotransferase level, weight and waist circumference were significantly decreased in the experimental group following the 6-week exercise training (P<0.05). High-density lipoprotein concentration was significantly increased in both groups. Gamma-glutamyl transferase level was decreased in the experimental group, but increased in the control group. The results showed no significant difference in the basic profile of participants, liver enzymes concentration and lipid profile between the experimental and control group. Conclusion: Six weeks of aerobic training may help prevent hepatic damage through decreasing serum levels of liver enzymes, anthropometric factors and some metabolic syndrome factors associated with nonalcoholic fatty liver disease.
Background and Objectives: The aim of the present study was to investigate the effect of six weeks of volleyball training on lipid and lipoprotein profiles of elite high school male volleyball players in the Golestan Province (Iran) during preparation season for an international championship in France. Methods: Training group included 12 elite volleyball players in students' premier league and control group included 12 healthy non-athlete male students. The training group practiced at 60-85% of maximum heart rate for six weeks, 90 minutes per session, six sessions per week and three sessions a day (first session: technical practice, second session: tactical practice and third session: technical/tactical practice). Blood samples were taken after 12 hours of fasting both before and after the training. Results: Level of total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C) and LDL-C/HDL-C increased in the training group (P> 0.05). However, there was a significant difference between the two groups in TC and LDL-C levels (P<0.05). Level of triglyceride, VLDL, and TC/HDL-C reduced in the training group after six weeks of training (P> 0.05). Conclusion: Our results show that the six-week volleyball training during the preparation season can cause abnormalities in plasma lipid profile.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
