PURPOSE: The present longitudinal study assessed cardiorespiratory capacity and running economy of Olympic athletes over several decades to measure changes in fitness in an elite group during aging. METHODS: Twenty-six male runners training for the 1968 Olympics were recruited. Heart rate, VO2max, ventilation, and running economy were measured in 1968, 1993, and 2013. In 2013, 22 of the original runners participated: three passed away between 1993 and 2013, and one declined to participate...

Robert A Nash
Doctored photographs can shape what people believe and remember about prominent public events, perhaps due to their apparent credibility. In three studies, subjects completed surveys about the 2012 London Olympic torch relay (Experiment 1) or the 2011 Royal Wedding of Prince William and Kate Middleton (Experiments 2-3). Some were shown a genuine photo of the event; others saw a doctored photo that depicted protesters and unrest. A third group of subjects saw a doctored photo whose inauthenticity had been made explicit, either by adding a written disclaimer (Experiment 1) or by making the digital manipulation deliberately poor (Experiments 2-3)...

PURPOSE: There is a limited amount of home advantage research concerned with winter sports. There is also a distinct lack of studies that investigate home advantage in the context of para sport events. This paper addresses this gap in the knowledge by examining home advantage in the Winter Paralympic Games. METHODS: Using a standardised measure of success, we compared the performances of host nations at home with their own performances away from home between 1976 and 2014...

Although there is research providing physiologically-based guidance for the content of the taper, this study was the first to examine how coaches actually implement the taper. The purpose of this study was to examine the taper planning and implementation processes of successful Olympic coaches leading up to major competitions and how they learned about tapering. Seven track and field coaches participated in semi-structured interviews exploring their tapering processes. To be considered for inclusion, coaches were required to have coached one or more athletes to an Olympic or Paralympic medal...

Rugby Sevens, a new Olympic sport, features high intensity intermittent running and contact efforts over short match durations, normally six times across two to three days in a tournament format. Elite Rugby Sevens seasons often include over a dozen competitive tournaments across less than nine months, demanding deliberate and careful training-stress balance and workload management alongside development of the necessary physical qualities required for competition. Focus on running and repeated power skills, strength, and match-specific conditioning capacities is advised...

Biathlon is an Olympic sport combining cross-country skiing with the skating technique and rifle shooting. The sprint (7.5 km for women and 10 km for men) includes two shootings between the three laps of skiing. The aims of the current study are to compare biathletes of different performance-levels and sex on total race time and performance-determining factors of sprint races in the biathlon World Cup. The top 10-performers (G1-10) and results within rank 21-30 (G21-30) in 47 sprint races during the 2011/2012 to 2015/2016 World Cup seasons were compared regarding total race time, course time, shooting time, range time, shooting performance (rate of hits) and penalty time...

The purpose of this study was to suggest a ranking prediction model using the competition record of the Ladies Professional Golf Association (LPGA) players. The top 100 players on the tour money list from the 2013-2016 US Open were analyzed in this model. Stepwise regression analysis was conducted to examine the effect of performance and independent variables (i.e., driving accuracy, green in regulation, putts per round, driving distance, percentage of sand saves, par-3 average, par-4 average, par-5 average, birdies average, and eagle average) on dependent variables (i...

The aim of this study was to test the hypothesis that pomegranate juice supplementation would blunt acute and delayed oxidative stress responses after a weightlifting training session. Nine elite weightlifters (21.0 ± 1 years) performed two Olympic-Weightlifting sessions after ingesting either the placebo or pomegranate juice supplements. Venous blood samples were collected at rest and 3 min and 48 h after each session. Compared to the placebo condition, pomegranate juice supplementation attenuated the increase in malondialdehyde (-12...

Joost Jansen, Godfried Engbersen
It is often believed that the Olympic Games have become more migratory. The number of Olympic athletes representing countries in which they weren't born is thought to be on the rise. It should, however, be noted that migration in the context of sports is hardly a new phenomenon. In this paper we hypothesise that, as a reflection of global migration patterns and trends, the number of foreign-born Olympians hasn't necessarily increased in all countries. Furthermore, it was expected that the direction of Olympic migration has changed and that foreign athletes increasingly come from a more diverse palette of countries...

A laboratory investigation of UV-C effects was conducted over a 62-h period: a much higher dose than in classic UV-C treatment was applied to five pigments and two painting binders used by prehistoric humans. Colorimetric parameters were compared to a control to see if UV-C can change pigment and binder color. Infrared spectroscopy, scanning electron microscopy, inductively coupled plasma and X-ray crystallography were also carried out to confirm colorimetric measurement. In order to understand how microorganism may physically deteriorate paintings, limestone blocks were painted and monitored until their complete colonization by algae, cyanobacteria, fungi and/or mosses...

Use of performance-enhancing drugs concern not only elite Olympic and Paralympic Games' athletes but also amateur athletes, who are making increasing use of substances and/or methods. Furthermore, a new frontier reached by the doping is the use of genes. World Anti- Doping Agency (WADA), expressly prohibited the participation in competitive sports by the athlete in case of taking banned substances to treat disease in the event that the above assumption implies an excessive improvement of performance. This study aims to analyze and show the doping control as an essential part of the anti-doping program to promote and protect the integrity of sport and athlete's health...

INTRODUCTION: KIR2DS5 is an activating human NK cell receptor of lineage III KIR. These include both inhibitory KIR2DL1, 2 and 3 and activating KIR2DS1 that recognize either the C1 or C2 epitope of HLA-C. In Europeans KIR2DS5 is essentially monomorphic, with KIR2DS5*002 being predominant. Pioneering investigations showed that KIR2DS5*002 has activating potential, but cannot recognize HLA-A, -B, or -C. Subsequent studies have shown that KIR2DS5 is highly polymorphic in Africans, and that KIR2DS5*006 protects pregnant Ugandan women from preeclampsia...
