Participation in Team Sports Can Eliminate the Effect of Social Loafing.

2016

The effect known as Ringelmann effect states that as group size increases, individual behavior may be less productive. If this decrease in productivity in groups is attributed to a decrement in individual motivation, it is called social loafing. We tested hypotheses that the collectivism associated with participation in team sports would reduce the level of social loafing compared to people who were not involved in team sports. In one experiment, participants ( n = 72; M age = 21.7 years, SD = 2.0) had to pull a rope individually and collectively. Groups of two, three, four, and six persons were formed from among individuals with no previous sports experience, and of those who had engaged …

Predictor variables for half marathon race time in recreational female runners

2011

Import JabRef | WosArea General and Internal Medicine; International audience; INTRODUCTION: The relationship between skin-fold thickness and running performance has been investigated from 100 m to the marathon distance, except the half marathon distance. OBJECTIVE: To investigate whether anthropometry characteristics or training practices were related to race time in 42 recreational female half marathoners to determine the predictor variables of half-marathon race time and to inform future novice female half marathoners. METHODS: Observational field study at the 'Half Marathon Basel' in Switzerland. RESULTS: In the bivariate analysis, body mass (r = 0.60), body mass index (r = 0.48), body …

Relationship between off-ice testing variables and on-ice speed in women's collegiate synchronized figure skaters: implications for training.

2010

The purpose of the current investigation was to identify any existing relationships between off-ice performance measures and on-ice performance quantified by speed and acceleration. Twenty-seven women (age 19 +/- 1 year; body mass (59.5 +/- 6.8 kg; height 164.6 +/- 6.35 cm; body fat 23.2 +/- 3.9%) who were collegiate synchronized figure skaters volunteered for the investigation. To examine the relationship between off-ice performance and on-ice speed and acceleration, collegiate synchronized skaters were evaluated on various performance tests over a 1-week period. Off-ice tests completed were peak torque for hip abduction and adduction, 40-yard sprint, vertical jump height, 30-second slide …

Diagnosis in track and field performances past the 1988 Ben Johnson doping scandal

1999

Beginning with the early 1960s, a lot of performance supporting effects have been integrated in the structure of track and field training, such as technical progress, theoretical knowledge of the training process, development of societies and medical steps, which among others include the forbidden use of steroids or other doping ‘techniques’. Since the integration of those effects took place quite fast, a logistic growth of world class performances concerning the years 1960–1988 can be observed in many disciplines especially if they were not far developed at the beginning of this period. Eight years (1989–1996) later, doping tests of world class athletes have spread (or should have spread) …

Direct and long-term detection of gene doping in conventional blood samples

2010

The misuse of somatic gene therapy for the purpose of enhancing athletic performance is perceived as a coming threat to the world of sports and categorized as 'gene doping'. This article describes a direct detection approach for gene doping that gives a clear yes-or-no answer based on the presence or absence of transgenic DNA in peripheral blood samples. By exploiting a priming strategy to specifically amplify intronless DNA sequences, we developed PCR protocols allowing the detection of very small amounts of transgenic DNA in genomic DNA samples to screen for six prime candidate genes. Our detection strategy was verified in a mouse model, giving positive signals from minute amounts (20 μl)…

Is it still important to be light in ski jumping?

2019

In ski jumping low body weight development resulted in some serious underweight problems and therefore the International Ski Federation (FIS) decided to solve the problem by relating maximum ski length to Body Mass Index (BMI) in 2004. The present study examined the current relationship between body weight, ski length and performance (jumping distance) in ski jumping. By adopting the BMI regulation to specifications for competition equipment, the FIS succeeded in stopping the alarming development of underweight problems in ski jumping. However, as the results of the present study show, the BMI regulation adopted by the FIS has reduced the advantage of being light, but despite the use of sho…

Developing narrative identities in youth pre-elite sport : bridging the present and the future

2019

Narrative research has contributed to understandings of athletic identity as an evolving story of the self that is creatively put together by the agentic individual but necessarily dependent on broader narratives within which we all live our lives. However, most studies in sport have focused on retrospective ‘big stories’ of athletes’ lives, rather than on-going, future-oriented identity construction through storytelling. In this study, we explored Finnish pre-elite athletes’ emerging stories of the self to understand the processes associated with the narrative selection and the resources they tap into in making sport meaningful to them. Nine women and eight men aged 17–18 were invited to c…

Restoring Harmony in the Lifeworld? : Identity, Learning, and Leaving Preelite Sport

2020

Sport provides many youth participants with a central life project, and yet very few eventually fulfill their athletic dreams, which may lead them to disengage from sport entirely. Many studies have explored the processes of athletic retirement, but little is known about how youth athletes actually reconstruct their relationship with sport and embodiment postretirement. The authors explored these issues in the story of “Pilvi,” a Finnish alpine skier who disengaged from sport in her late adolescence. Employing an existential-phenomenological approach, they conducted six low-structured interviews with Pilvi, combined with visual methods, and identified key themes relating to the body, space,…

The Quantified Athlete: Associations of Wearables for High School Athletes

2018

The adoption of wearable technology in competitive sports can be an advantage to performance and training. Athletes who use personalised data to quantify their performances with the possibilities of sharing with others may use wearables to reinforce the athletic identity. Despite these changes, few studies have actually examined the associations between wearables and developing athletes in their quest for professional sports. Student athletes (n = 437, age = 17y) still in high schools completed a web-based survey about their professional aspirations, athletic identity, and the association with wearables. Wearables were measured by ownership and usage of apps, fitness trackers, or sports wat…
