EFFECT OF FAST-SKIN BODY SUIT ON PROPULSION IN FOUR STROKES BY USING INDIRECT MEASUREMENT OF ACTIVE DRAG (IMAD)

The effect of Fast- skin suit compared to conventional swimsuits on propulsion in four strokes in 16 female national-level swimmers was studied. The propulsion was estimated by Indirect Measurement of Active Drag (IMAD). IMAD is an estimate of the overall propulsive drag on a swimmer measured in conditions near maximal speed. Remarkable difference in propulsive force has been obtained for butterfly swim: 15%, while 5.2% was achieved for backstroke. Our findings also showed that Fast-skin effect is more important in breaststroke; 9.5% than in even front crawl; 7.9%. The method has also enabled us to find out the changes in mean velocities; 5.7% for butterfly and 1.8% for back crawl and for maximal velocities 16.5% for butterfly and 3.4% for back crawl

DETERMINATION OF ARM AND LEG CONTRIBUTION TO PROPULSION AND PERCENTAGE OF COORDINATION IN BUTTERFLY SWIMMING

The Indirect Measurement of Active Drag (IMAD) was used to study the contribution of the legs and arms to propulsion in butterfly swimming. Contrary to MAD (Measuring of Active Drag) system, the IMAD can be used for all strokes and therefore enabled us to study the butterfly swim to estimate not only the percentage of leg and arm contribution to propulsion but also the percentage of swimmers’ arms and legs co- ordinations. The method revealed that the best coordination was 78.% and that the contribution of arms and legs in propulsive force were 92% and 66% and in velocities were 98% and 88% respectively, showing that the swimmers received arm contribution better than leg contribution in propelling and velocity

Effect of self-care training program on quality of life of elders‏

Background & Aims: Nowadays the elderly population is growing all over the world. Diseases and conditions resulting from this evolutionary process can be costly to governments and cause many disabilities which severly affect the erderly’s quality of life. This study aims to determine the effect of self-care training program on quality of life of elderly. Material & Methods: It is a controlled randomized trial which was carried out on 60 elderly referred to Omid’s elderly care center in Borougen city. After convenience sampling, the elderly were randomly assigned to two groups of experimental (n=30) and control (n= 30) groups. The experimental group participated in a three months self- care training program. Data was collected by the Short Form Health Survey (SF-36) and analyzed using SPSS-PC (v.11). Results: The findings showed a significant difference in the mean scores of quality of life between the experimental and control groups (P<0.05) after intervention. Conclusion: Self- care education to elderly about the practices of proper nutrition, exercise, rest and medication can prevent a lot of problems and help them to improve their quality of life

An Assessment of the Effect of Recitation of the Quran on Exam Anxiety in Nursing and Emergency Medicine Students‏

Background & Objective: Anxiety is a feeling of apprehension caused by the feeling of being at risk and can affect the performance of an individual. Today, exam anxiety is increasingly observed among educated people and this situation causes a loss of concentration. Faith increases confidence and patience and strength to deal with problems. The aim of this study was to assess the effect of recitation of the Quran on exam anxiety in nursing and emergency medicine students. Methods: This was a quasi-experimental study performed on nursing and emergency medicine students of Borujen School of Medical Emergency Nursing, Iran. The purposive sampling method was used in the present study and all students participated in this study. The courses presented during one semester for each field of study were randomly divided into two groups. An audio of Maryam Surah, verses 1 to 26, were played for one group before the midterm exams and the other group before the end of term exams for 5 minutes. Data collection was performed using a demographic questionnaire and Spiel berger’s State-Trait Anxiety Inventory (STAI) before all exams. Data analysis was performed using descriptive and analytic statistics (such as independent t-test and paired t-test) in SPSS software. Results: The results of this study showed that the mean levels of apparent anxiety in nursing students during exams without Quran recitation was 48.73±13.52 and during exams with Quran recitation was 44.72±15.26. The average level of hidden anxiety during exams without Quran recitation was 43.33 ± 9.61 and in exams with Quran recitation was 41.36±11.99. A statistically significant difference was observed among these averages (P<0.05). The mean levels of apparent anxiety in emergency medicine students during exams without Quran recitation was 41±12.98 and during exams with Quran recitation was 39.11±11.82. The average level of hidden anxiety during exams without Quran recitation was 41.33±8.78 and during exams with Quran recitation was 38.46±11.01. A statistically significant difference was observed among these averages (P<0.05). Conclusion: The results showed that the sound of the Quran before exams can reduce students’ anxiety levels. Therefore, it is recommended that managers and policy makers consider the results of this study, and play audios of the Quran before exams in order to reduce stress but also take steps to promote familiarity with the Quran
