The Training and Development of Elite Sprint Performance: an Integration of Scientific and Best Practice Literature.
2019
Despite a voluminous body of research devoted to sprint training, our understanding of the training process leading to a world-class sprint performance is limited. The objective of this review is to integrate scientific and best practice literature regarding the training and development of elite sprint performance. Sprint performance is heavily dependent upon genetic traits, and the annual within-athlete performance differences are lower than the typical variation, the smallest worthwhile change, and the influence of external conditions such as wind, monitoring methodologies, etc. Still, key underlying determinants (e.g., power, technique, and sprint-specific endurance) are trainable. In th…
Influence of Psychological Factors in Federated Futsal and Lifeguard Athletes, Differences by Gender and Category
2021
This research aims to analyse the differences in optimism, resilience, engagement and competitive anxiety as a function of the sport modality practiced in lifeguarding (individual sport) and futsal (team sport); the sport category by age (cadet or youth) and gender. The LOT-R optimism questionnaire, the Connor-Davidson Resilience Scale (CD-RISC-10), the Utrecht Work Engagement Scale (UWES) and the Competitive Anxiety Scale (SAS-2) were applied to a sample of 189 participants (139 men and 50 womwn) aged between 14 and 17 years. The following statistical tests are performed: Cronbach's alpha, Pearson's linear correlation, Student's t-test, Kolmogorov-Smirnov test, Levene's test and multivaria…
Do perceived justice and need support of the coach predict team identification and cohesion? Testing their relative importance among top volleyball a…
2011
Objectives: Based on findings in organizational psychology, the aim of the present study was to test the relevance of perceived justice and need support of the coach in team sports. Specifically, two studies examined their relation with athletes’ team identification and team cohesion. Design: Two cross-sectional, questionnaire studies conducted after a midseason game day. Methods: In study 1, Belgian top level female volleyball players (N ¼56; M ¼22.33) and male handball players (N ¼35; M ¼23.59) completed web-based questionnaires assessing athletes’ perceived justice and need support of the coach and their team identification and cohesion. In study 2, Norwegian top level female handball pl…
Antidoping Science
2018
The ineffectiveness of antidoping programs in elite sport, largely due to human and political factors, is leading to a new resolve and greater transparency of antidoping authorities and those stakeholders interested in drug-free sport. The perception by the public, athletes, and the World Anti-Doping Agency (WADA) of antidoping science and current drug testing programs in elite sport varies widely from "ineffective" to "robust and reliable." Here, we discuss why a careful and considered reevaluation of the underlying premise of antidoping science is needed to bring this unique application of predictive/diagnostic science more in line with other areas of medicine. We show how the validity of…
Oxygen uptake kinetics and energy system's contribution around maximal lactate steady state swimming intensity
2017
Made available in DSpace on 2018-11-26T17:20:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-02-28 Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Ministry of Education of Brazil The purpose of this study was to examine the oxygen uptake ((V) over dotO(2)) kinetics and the energy systems' contribution at 97.5, 100 and 102.5% of the maximal lactate steady state (MLSS) swimming intensity. Ten elite female swimmers performed three-to-five 30 min submaximal constant swimming bouts at imposed paces for the determination of the swimming velocity (v) at 100% MLSS based on a 7 x 200 m intermittent incremental protocol until voluntary exhaustion to find the v associated…
Impact of oral contraceptive use and menstrual phases on patellar tendon morphology, biochemical composition, and biomechanical properties in female …
2013
Sex differences exist with regards to ligament and tendon injuries. Lower collagen synthesis has been observed in exercising women vs. men, and in users of oral contraceptives (OC) vs. nonusers, but it is unknown if OC will influence tendon biomechanics of women undergoing regular training. Thirty female athletes (handball players, 18–30 yr) were recruited: 15 long-term users of OC (7.0 ± 0.6 yr) and 15 nonusers (>5 yr). Synchronized values of patellar tendon elongation (obtained by ultrasonography) and tendon force were sampled during ramped isometric knee extensor maximum voluntary contraction to estimate mechanical tendon properties. Furthermore, tendon cross-sectional area and lengt…
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) …
Toward a conceptual understanding of acute cultural adaptation: A preliminary examination of ACA in female swimming
2012
This paper considers a novel approach to researching adaptation in transnational athletes. The first part introduces a conceptualisation of acute cultural adaptation (ACA), which extends the current literature in sport psychology by offering original insights into mechanisms underpinning adaptive processes to a new cultural site during an interim relocation. Rereading a self-determination theory through the lens of cultural epistemology, the proposed theorisation suggests that ACA is realised in everyday practices drawing on a range of material and symbolic cultural resources to satisfy basic psychological needs. The second part of the paper engages the conceptualisation of ACA to make sens…
A Gamified Mobility Experience
2020
We believe in the use of urban games to define new enjoyable experiences, change citizens’ unsustainable habits and educate them to new environment-and social-friendly ones. This paper presents MUV, an innovative action that has the power to engage citizens and foster sustainable mobility behaviors. MUV complements engaging HMIs with a participatory method within an iterative innovation process called the virtuous cycle (understand, involve, co-create, implement, experiment). The innovation process has led to a new game dynamic: Mobility as a Sport. It results in a rewarding personal mobility experience; the same rewarding sensations the athletes feel when they improve their results.
Er supermosjonisme sunt? : kartlegging av helsevariabler blant mannlige langdistanseløpere og syklister.
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Introduction: Physical activity is well documented as an important factor for good health. There are however some people who train far beyond the national recommendations for 6 physical activity combined with work and family life. The research done on «high volume exercisers» is limited, specially the health variables. Objective: The purpose with this master paper is to investigate if high volume exercise is healthy. By identifying different health variable it may point to how the body responds to high training volume. Method: 41 male high volume exercises (18 to 50 years) were included in this cross-sectional study. The compila…
