Improved performance has been reported for master runners (i.e. athletes older than 40 years) in both single marathons and single ultra-marathons. This study investigated performance trends of age group ultra-marathoners competing in all 100 km and 100 miles races held worldwide between 1971 and 2013. Changes in running speeds across years were investigated for the annual ten fastest 5-year age...
Abstract The objective of this study was to evaluate the influence thermal shock on oocytes used in production vitro embryos (IVP) high productivity Holstein cows day follicular aspiration (OPU; 0), 30, 60 and 90 days before OPU. From mean temperature 0 previous days, they were classifed into comfort group (TC; up 15°C) heat stress (HS; above groups.Anegative observed viable (total grade I). pe...
BACKGROUND Thrombelastography is a useful tool in assessment of hemostasis. Beside the traditional variables, the velocity curve and the variable delta have lately earned attention. The velocity curve provides knowledge about the speed of clot formation including information about thrombin generation. Delta, which only reflects enzymatic coagulation, allows the determination of the origin of hy...
BACKGROUND Microvascular injury (MVI) after coronary ischemia-reperfusion is associated with high morbidity and mortality. Both ischemia and reperfusion are involved in MVI, but to what degree these phases contribute is unknown. Understanding the etiology is essential for the development of new potential therapies. METHODS AND FINDINGS Rats were divided into 3 groups receiving either 30 minut...
the purpose of this study was to investigate the effects of short term creatine monohydrate as an ergogenic supplement on the sprint performance and muscular strength of wrestlers. 20 wrestlers were selected randomly and divided into two groups. one group was placebo group (control) and the other group was creatine supplement group (experimental). in a double blind project, subjects' speed...
OBJECTIVE To evaluate sarcopenic indices in relation to respiratory muscle strength (RMS) in elderly people. METHODS This study included 65 volunteers over the age of 60 (30 men and 35 women). The skeletal muscle mass index (SMI) was measured using bioimpedance analysis. Limb muscle function was assessed by handgrip strength (HGS), the Short Physical Performance Battery (SPPB), and gait speed...
در این پژوهش از 30 راس گاو هلشتاین با روزهای آبستنی 270 روز، در قالب طرح بلوک های کامل تصادفی با اندازه گیری های تکرار شده استفاده شد. گاوها به طور تصادفی به سه تیمار آزمایش و بر اساس تعداد زایش به دو بلوک (یک بار زایش کرده و چند بار زایش کرده) اختصاص داده شدند. تیمارهای آزمایشی شامل دوره خشکی معمول 60 روز، دوره خشکی 45 روز و دوره خشکی 30 روز بود. نتایج به دست آمده نشان داد که گاوهایی با طول دو...
BACKGROUND Slow walking speed in elderly people predicts increased morbidity and mortality. We examined factors that may be associated with decreased habitual walking speed in older men and women. METHODS Older (range: 60-88 years, mean = 72.5 years) men (n = 25) and women (n = 24) were recruited. The Short Physical Performance Battery, body composition, VO(₂peak) on a treadmill, VO₂ and rate...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
