Learning in sport : from life skills to existential learning

2020

Youth sport is habitually promoted as an important context for learning that contributes to a person’s broader development beyond sport-specific skills. A growing body of research in this area has operated within a life skills discourse that focuses on useful, positive and decontextualised skills in the production of successful and adaptive citizens. In this paper, we argue that the ideological discourse of life skills, underpinned by ideas about sport-based positive youth development, has unduly narrowed the research on learning in sport to only what is deemed functional, teachable, and economically productive. After considering the problems associated with the currently dominant life skil…

Relationship between Training Load Management and Immunoglobulin A to Avoid Immunosuppression after Soccer Training and Competition: A Theoretical Fr…

2021

Immunoglobulin A (IgA), which is the main effector against upper respiratory tract viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been related to training load management. The aim of this systematic review was to establish the relationship between training load and salivary IgA based on current evidence in order to avoid immunosuppression after exercise and players´ vulnerability to virus contagion. A systematic review of relevant articles was carried out using two electronic databases (PubMed and Web of Science) until 19 May 2021. From a total of 127 studies initially found, 23 were included in the qualitative synthesis. These studies were clustered depen…

A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes

2021

BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…

Field location and player roles as constraints on emergent 1-vs-1 interpersonal patterns of play in football

2017

This study examined effects of player roles on interpersonal patterns of coordination that sustain decision-making in 1-vs-1 sub-phases of football in different field locations near the goal (left-, middle- and right zone). Participants were fifteen U-16 yrs players from a local competitive amateur team. To measure interpersonal patterns of coordination in the 1-vs-1 dyads we recorded: (i) the relative distance value between each attacker and defender to the centre of the goal, and (ii), the relative angle between the centre of the goal, each defender and attacker. Results revealed how variations in field locations near the goal (left-, middle- and right-zones) constrained the relative dist…

Young athletes’ significant experiences in sport : critical sociological reflections on athlete development

2017

AbstractThe aim of this article is to provide a sociological perspective on athlete development by using the theoretical framework of socialization and life course. Significant experiences are used as an interpretational tool to study young athletes’ perceptions of their socialization process. The research data, which were collected at a sports upper secondary school, consist of life historical interviews with 26 young athletes aged 14–17 years. Through content analysis, their significant experiences in sports were divided into four categories and then analyzed further in relation to the Habermasian dualistic reality of the lifeworld and the system. The results were the following. First, no…

Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 Background: Muscle strengthand poweris a determining feature of performance in many different sports and thephysiologicalfactors that affect muscle functionare many. Previous studies have mostly concernedadult athletes, while researchfeaturing young elite athletes or differences between sports have been scarce. Purpose: The study’s purposeis to investigate possibleconnectionsbetween physiological factors such as resting metabolic rate, protein intake, and fat-free mass and muscle functionamong young elite athletes in southern Norway.Differences between sport-groupswere alsoinvestigated. Method: A total of 36young elite athlet…

Relationship between inflammatory biomarkers and testosterone levels in male master athletes and non-athletes.

2021

Background Aging is often associated with low-grade systemic inflammation and reduced anabolic hormone levels. To investigate whether lifelong exercise training can decrease the age-related low-grade inflammation and anabolic hormone levels, we examined hormonal and inflammatory parameters among highly-trained male masters athletes and age-matched non-athletes. Methods From 70 elite power and endurance master athletes – EMA (51.3 ± 8.0 yr), 32 young controls - YC (23.7 ± 3.9 yr) and 24 untrained age-matched controls - MAC (47.2 ± 8.0 yr) venous blood was drawn to measure inflammatory parameters (interleukin-6 [IL-6], tumor necrosis factor-α [TNF-α] and interleukin-10 [IL-10]) and circulatin…

Participation and performance trends in 100-km ultra-marathons worldwide

2014

The aims of the present study were to (1) investigate the participation trends for the origin of athletes competing in 100-km ultra-marathons and (2) determine the nationalities of athletes achieving the fastest 100-km race times worldwide. Race times and nationality from 112,283 athletes (15,204 women and 97,079 men) from 102 countries who completed a 100-km ultra-marathon worldwide between 1998 and 2011 were investigated using single- and multi-level regression analyses. The number of finishers increased exponentially, both for women and men. Most of the finishers (73.5%) were from Europe, in particular, France (30.4%). The number of finishers from Japan, Germany, Italy, Poland and the Un…

European athletes dominate performances in Double Iron ultra-triathlons - A retrospective data analysis from 1985 to 2010

2014

International audience; We investigated the participation and performance trends of ultra-endurance triathletes from all nationalities competing in a Double Iron ultra-triathlon (7.6-km swim, 360-km cycle and 84.4-km run) from 1985 to 2010. A total of 1854 athletes participated in 92 Double Iron ultra-triathlons. The majority of the winners came from Europe with 72 victories, followed by North America with 17 victories. The race time for the European ultra-triathletes was 1340 (s=95.3) min, decreasing highly significantly (r(2)=0.28; P<0.0001) across the years. North American ultra-triathletes finished the races within 1556 (s=124.5) min; their race time showed no changes across the years (…
