The requisite combination of speed, power, and strength necessary for a bobsled push athlete coupled with the difficulty in directly measuring pushing ability makes selecting effective push crews challenging. Current practices by USA Bobsled and Skeleton (USABS) utilize field combine testing to assess and identify specifically selected performance variables in an attempt to best predict push performance abilities. Combine data consisting of 11 physical performance variables were collected from 75 subjects across two winter Olympic qualification years (2009 and 2013)...

BACKGROUND: The Goldman dilemma presented athletes with a Faustian bargain that guaranteed winning an Olympic gold medal in their sport but resulted in certain death 5 years later. Athletes' responses to Goldman's bargain were reported from 1982 to 1995. Several studies subsequently evaluated people's willingness to accept the bargain proposed in the Goldman question. Our study updates Goldman's question using contingent-behavior questions, a preference-elicitation method widely applied in economics, marketing and psychology to understand people's choice behavior...

It is important to understand factors associated with sport participation for youth with intellectual and developmental disabilities (IDD). With a sample of 414 Special Olympics (SO) athletes, this study examined how frequently involved athletes differ from other youth who are less involved in SO. Results showed that frequently involved athletes are older, have more sport-specific parental support, stronger athlete-coach relationships, and more positive SO experiences than other athletes. These factors were predictive of SO involvement, even after controlling for athlete characteristics, including behavior problems and adaptive behavior...

Purpose To describe the occurrence of imaging-depicted sports-related stress injuries, fractures, and muscle and tendon disorders during the 2016 Summer Olympic Games in Rio de Janeiro, Brazil. Materials and Methods Data on radiologic examinations were collected and retrospectively analyzed centrally by two board-certified musculoskeletal radiologists (with a third musculoskeletal radiologist acting as an adjudicator in case of discrepancies). Descriptive data on all imaging examinations by using radiography, ultrasonography (US), and magnetic resonance (MR) imaging were collected and analyzed according to imaging modality, country of origin of the athletes, type of sport, and type and location of injury...

This study aimed to determine which contractile properties measured by tensiomyography (TMG) could better differentiate athletes with high- and low-power values, as well as to analyse the relationship between contractile properties and power production capacity. The contractile properties of the vastus medialis (VM), rectus femoris (RF) and vastus lateralis (VL) of an Olympic women's Rugby Sevens team (n = 14) were analysed before a Wingate test in which their peak power output (PPO) was determined. Athletes were then divided into a high-power (HP) and a low-power (LP) group...

Rowers need to combine high sprint and endurance capacities. Muscle morphology largely explains muscle power generating capacity, however, little is known on how muscle morphology relates to rowing performance measures. The aim was to determine how muscle morphology of the vastus lateralis relates to rowing ergometer performance, sprint and endurance capacity of Olympic rowers. Eighteen rowers (12♂, 6♀, who competed at 2016 Olympics) performed an incremental rowing test to obtain maximal oxygen consumption, reflecting endurance capacity...

Men outperform women in sports requiring muscular strength and/or endurance, but the relative influence of "nurture" versus "nature" remains difficult to quantify. Performance gaps between elite men and women are well-documented using world records in second, centimeter or kilogram sports. However, this approach is biased by global disparity in reward structures and opportunities for women. Despite policies enhancing female participation (Title IX legislation), USA women only closed performance gaps by 2 and 5% in Olympic Trial swimming and running, respectively, from 1972 to 1980 (with no change thereafter through 2016)...
