Some people think that old persons should not make too much effort or should save their strength and rest because of their age. They think themselves too old to do some physical activities because they think that it is too late to start exercising‚ exercising can put them falling down and they cannot follow physical activities because they are not able to do it. In the contrary this article show how these old people should do exercise because of the benefits for the body‚ the maintenance of health

fatigue life and tensile strength for magnesium alloy were investigated in this study. At least 20 specimens were tested to obtain the scatter data of fatigue limit‚ fatigue life and tensile strength‚ respectively. The probability distributions of fatigue limit‚ fatigue life and tensile strength were evaluated by using Normal distribution and Weibull distribution function. The values of the Weibull modulus‚ m were 159‚ 10‚ 175 for fatigue limit‚ fatigue life and tensile strength‚ respectively. Therefore

totally dependent on other persons in daily life. The vast majority of individuals with RA belong to FC II. Pain‚ stiffness‚ and fatigue generally occur early in the course of RA. Reduction of body function‚ such as range of motion (ROM)‚ muscle strength‚ and aerobic capacity‚ may follow. As previously summarized by van den Ende et al (5)‚ 50% of patients with RA displayed decreased hand ROM at their first rheumatology visit. Two years later‚ reduced ROM was found in large joints; the decreased

Properties of paper Physical Properties Basis Weight or Grammage The basis weight‚ substance or grammage is obviously most fundamental property of paper and paperboard. The Basis weight of paper is the weight per unit area. This can be expressed as the weight in grams per square meter (GSM or g/M2)‚ pounds per 1000 sq. ft. or weight in Kgs or pounds per ream (500 sheets) of a specific size. Paper is sold by weight but the buyer is interested in area of paper. The basis weight is what

mechanical stre ngth of cement by applying Compressive and Tensile tests on Cement-Sand mortar. Standards: ¾ Compressive strength of cement using mortar cubes: B.S.12 – Part 2 ASTM : C 109 ¾ Tensile strength of mortar using briquettes: B.S.12 – Part 2 ASTM : C 109 General Discussion: In these tests (Compressive and Tensile tests) we measured the mechanical strength of the hardened cement. These tests are done on cement – sand mortar and not on the hardened cement itself‚ the r eason

manufacture ribs‚ stiffeners and other elements from the PPS composites. The individual components are welded together to form a strong‚ inseparable unit. This process eliminates the need for costly drilling & riveting operations & achieves higher strength and safety – reducing weight & saves time and money. Components made from PPS composites remain hard‚ impact-resistant‚ stiff & stable‚ even when exposed to high temperatures. PPS is also resistant to aviation fuel‚ engine and hydraulic

Volleyball Components of Fitness are the different types of components an athlete uses when playing a sport or event. In volleyball there are three specific components of fitness that are mostly described in the sport‚ Agility‚ Power and Strength. 1. Agility The word Agility is defined as‚ “The ability to perform a series explosive power movements in rapid succession in opposing directions (e.g. Zig-zag running or cutting movements).” Agility is a major component needed

BENEFITS OF PHYSICAL FITNESS The benefits of physical fitness are numerous and include better health‚ greater strength‚ more flexibility‚ increased energy‚ improved appearance‚ and a more positive attitude and mood. Regular exercise can lead to both immediate and long-term benefits. Regular physical activity has been shown to reduce the morbidity and mortality from many chronic diseases. The benefits of fitness far outweigh the inconveniences of regular exercise. To reap the maximum benefits of

observed that “exercise and temperance can preserve something of our strength in old age.” Aristotle stressed the need for exercise to maintain “a healthy mind in a healthy body.” In the Misneh Torah‚ the twelfth century Jewish scholar and physician‚ Rabbi Moses Maimonides‚ strongly recommended daily exercise and warned that “anyone who sits around idle and takes no exercise will be subject to physical discomforts and failing strength.” Early in the eighteen century‚ the renowned British physician
