BACKGROUND Age-related decline in muscle power may be an early indicator of balance deficits and fall risk, even in nonfrail adults. This study examined the dose-dependent effect of power training on balance performance in healthy older adults. METHODS One hundred twelve community-dwelling healthy older adults (69 +/- 6 years) were randomized to 8-12 weeks of power training at 20% (LOW), 50% ...
Objective: The aim of this study was to investigate the effect of eight weeks of high intensive exercise on selected biomechanical and anthropometrical variables in elite wrestlers. Methods: Sixteen young wrestlers (age 19.1±1 years and weight 74.9±17.3 kg) attending the national Greco-Roman camps participated in this study. Biomechanical and anthropometrical variables included...
The atomic force microscope ~AFM! is a powerful tool for investigating surfaces at atomic scales. Harmonic balance and power balance techniques are introduced to analyze the tapping-mode dynamics of the atomic force microscope. The harmonic balance perspective explains observations hitherto unexplained in the AFM literature. A nonconservative model for the cantilever–sample interaction is devel...
this paper compares the value relevance of book value and dividends versus book value and reported earnings. the main purpose of this study explains which of dividends, book value and earnings are more value relevance. thus, we have examined 98 firms of tehran stock exchange over a period 1377-1382. our methodology of examining the information content of various income statement and balance she...
Heat transfer in internal combustion engines is one of the most significant topics. Heat transfer may take place through thermal conduction and thermal convection in spark ignition engines. In this study, valve cover heat transfer and thermal balance of an air-cooled engine are investigated experimentally. The thermal balance analysis is a useful method to determine energy distribution and effi...
