Genetic polymorphism is considered to be associated with human physical performance. The angiotensin I-converting enzyme insertion/deletion (ACE I/D) and the α-actinin-3 gene (ACTN3) R577X polymorphisms have been widely investigated for such associations, and functional ACE I/D and ACTN3 R577X polymorphisms have been associated with sprinter performance. The aim of this study was to determine t...

OBJECTIVE AND METHODS Asthma is often reported by elite athletes, especially endurance athletes. The aim of this article is to review current knowledge of mechanisms and management of exercise-induced asthma (EIA) in adult elite athletes. RESULTS The mechanisms underlying EIA is incompletely understood, but the two prevailing hypotheses are the hyper-osmolarity and the thermal hypothesis. Bot...

This paper estimates the causal effect of elite college admission on students’ chances of reaching top management positions, and decomposes the total effect into a component attributable to ties formed between college peers and a component attributable to other institutional inputs. I construct a novel dataset linking archival records of applications to elite colleges in Chile to the census of ...

Although elite styles are important to the formation of generalised dress styling trends, the elite fashions that appear in the mass media are inaccessible to most consumers. When people buy new mass produced clothing, they choose necessarily from the limited range of styles available in nearby retail stores that are also within their income-based price threshold. In turn, the styles available ...

This study highlights recent observations in tennis which have revealed that the head position and gaze direction during the hitting process distinguished significantly elite players (with significant results in Grand Slam tournaments) from other top players: Elite players spent more time tracking the ball and fix the contact zone (or hitting zone) throughout the hitting action. These character...

the purpose of the present study is to examine the effects of ego depletion on arousal of elite iranian swimmers. the sample comprised elite swimmers invited to the national swimming team as focused and semi focused (36 subjects). the research design was as pre- and post-test—in two phases of ego depletion conditions and the lack of ego depletion conditions in two experimental and control group...

Although a robust literature has demonstrated a positive relationship between education and socio-economic attainment, the processes through which formal schooling yields enhanced economic and social rewards remain less clear. Employers play a crucial role in explaining the returns to formal schooling yet little is known about how employers, particularly elite employers, use and interpret educa...

Despite the variation in swimming performance of elite triathletes is generally small, longitudinal observations of swimming performance in the top 20 elite triathletes in the world compared to that of the remaining field indicate that swimming performance is crucial at Olympic distance triathlon at elite level (Bentley et al., 2008). Therefore, researches that addresses optimization of swim pe...

Investigating the immune system of human immunodeficiency virus (HIV) elite controllers, or HIV-infected individuals who maintain undetectable plasma HIV RNA levels without antiretroviral therapy (ART), has led to advances in our understanding of HIV pathogenesis [1] and may be critical to the development of a functional cure for HIV infection [2, 3]. However, although other studies have shown ...
