where the first inequality is an application of the triangle inequality, the second follows from (1) and (2), and the third from the choice of m. Therefore, since our choice of > 0 was arbitrary, we conclude that the subsequence (xnm)→ b. A similar argument using the sequence (zm) given by zm = inf{xm, xm+1, . . .} and the version of Lemma 1.3.7 suitable for infima (see Exercise 1.3.2, which yo...

The aim of this research was to study the effect of warm up with two different type intensity on plasma antioxidant enzymes and damage indices of lipid, protein and DNA after intensive activity in non-athlete males. 12 non athlete students of kharazmi University participated in this study. Firist, subjects VO2peak were measured by Gas analyzer (Meta Max 3B) on the ergometer cycle with increment...

It is common among competitive baseball players to swing bats while in the batter's box in an attempt to improve their batting performance. Players use bats of different weights during this time, and only a few studies have evaluated the optimal bat weight to increase performance. Previous studies have not investigated the optimal rest period after a warm-up with bats of varying weights. Theref...

The purpose of the current research was to study the effect of a warm-up program including submaximal half-squats on vertical jumping ability. Twenty physically active men participated in the study. Each subject performed 5 sets of half-squats with 2 repetitions at each of the following intensities: 20, 40, 60, 80, and 90% of the 1 repetition maximum (1RM) load. Prior to the first set and immed...

The purpose of this review is to determine how throwing overweight and underweight baseballs affects baseball throwing velocity and accuracy. Two studies examined how a warm-up with overweight baseballs affected throwing velocity and accuracy of 5 oz regulation baseballs. One of these studies showed significant increases in throwing velocity and accuracy, while the other study found no signific...

The West Antarctic ice sheet is the last ice sheet of the type cradled in a warm, marine geologic basin. Its perimeter stretches into the surrounding seas allowing warmer ocean waters to reach the undersides of its floating ice shelves and its relatively low surface elevation permits snow-carrying storms to extend well into its interior. This special environment has given rise to theories of im...

BACKGROUND The relation of the warm-up ischemia phenomenon to the presence and intensity of initial myocardial ischemia is unclear. We sought to determine whether the warm-up ischemia phenomenon requires initial myocardial ischemia or can be induced by exercise without ischemia and whether there is a relation between the intensity of initial ischemia and the attenuation of ischemia on reexercis...

BACKGROUND/AIMS Atrial natriuretic peptide (ANP) protects against hypoxia/reoxygenation-induced damage of cultured hepatocytes, thus suggesting a therapeutic potential in the liver. Therefore, the effects of ANP on hepatic ischemia/reperfusion injury after warm ischemia were studied. METHODS Livers of male Sprague-Dawley rats subjected to 60 minutes of warm ischemia at 37 degrees C were perfu...

the six-minute walk test (6mwt) is a well-tolerated test which reflects daily activities and can be easily used in clinical practice. the 6mwt provides information about functional capacity, response to therapy and prognosis across a range of chronic cardiopulmonary conditions. moreover, the 6mwt is sensitive to the common therapies used for chronic obstructive pulmonary disease, such as pulmon...

OBJECTIVE: Cardiac Rehabilitation Program (CRP) is a comprehensive program developed specifically for the patients aims to improve functional exercise capacity, quality of life, and psychosocial status. This study investigate effect CRP in retrospectively on who went through percutaneous coronary interference (PCI) with artery disease (CAD) diagnosis bypass graft (CABG) history.MATERIAL AND MET...
