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
