Sexual Harassment and Abuse among Young Elite Athletes, Recreational Athletes, and Reference Students: A Prospective Study.
2022
Purpose: To examine the 12-months prevalence and 12-months prospective change in reported sexual harassment and abuse (SHA)-victimization among young elite athletes, recreational athletes, and reference students in three different social settings and identify the perpetrators. Methods: In total, 919 adolescents responded to an online questionnaire in 12th grade (T1) and 13th grade (T2). The sample consisted of elite athletes (n = 482) and recreational athletes (n = 233) attending Norwegian elite sport high schools (n = 26), and reference students (n = 200) attending ordinary high schools with no sport specialization (n = 6). Data were analyzed using Independent sample t-test, Pearson Chi-Sq…
Differences in kinematic and match-play demands between elite winning and losing wheelchair padel players
2020
We aimed to compare the match-play and kinematic demands of the translation and rotation movements of elite wheelchair padel players as a function of match results. Twenty-two elite male players were video-analysed with a two-dimensional direct linear transformation (DLT) -corrected video system across seven matches of a professional tournament. Distance, turns, changes of direction, linear and angular speed, acceleration and the players’ heart rate (HR) were recorded. Losing couples in wheelchair padel covered greater distances than winners (P <0.001; r = 0.024) and did so at a higher speed (P <0.001; r = 0.06), while making greater efforts by accelerating (P <0.001; ∅ = -0.021), braking (…
Effect of mountain ultramarathon distance competition on biochemical variables, respiratory and lower-limb fatigue
2020
The study aimed at assessing the acute physiological effects of running a 65-km vs a 107- km mountain ultramarathon. Nineteen athletes (15 males and 4 females) from the shorter race and forty three athletes (26 males and 17 females) from the longer race were enrolled. Body weight, respiratory and lower limb strength were assessed before and after the race. Blood samples were obtained before, after and 24-h post-race. Body weight loss did not differ between races. A decrease in squat jump height (p<0.01; d = 1.4), forced vital capacity (p<0.01; d = 0.5), forced expiratory volume in 1 s (p<0.01; d = 0.6), peak inspiratory flow (p<0.01; d = 0.6) and maximal inspiratory pressure (p<0.01; d = 0.…
Factors associated with body size perception among adolescent goal-oriented sports participants and non-participants : a cross-sectional Finnish study
2022
Abstract Background Regardless of competitive athletes’ body image pressures, only few studies have focused on adolescent sport participants’ body image and the findings are inconclusive. Furthermore, the role of competitive goals in sports on adolescents’ body size perception has not been studied. We examined the factors associated with adolescents’ competitive goals in sports and body size perception, and the associations between adolescents’ competitive goals in sports and body size perception. Methods The cross-sectional study consisted of 475 goal-oriented sports club participants and 936 reference youths (aged 14–16 years). The study questionnaire included multiple choice items on hea…
Physical activity, use of alcohol and smoking in middle-aged and aging men. A longitudinal study among Finnish male former athletes and controls
2020
It is not known whether decrease in physical activity (PA) is associated with binge drinking among former athletes. The purpose of this study was to investigate the reciprocal associations between PA and use of alcohol among former athletes and controls at four time points. Furthermore, we examined whether there were longitudinal latent profiles related to use of alcohol, smoking and PA during the follow-up. Finnish male former elite athletes (n = 1633) and matched controls (n = 1099) questionnaire-reported their PA, alcohol consumption and smoking at four time points in 1985, 1995, 2001 and 2008. Former athletes were more physically active and smoked less than controls, but in all profiles…
Talent Development Environments in Football: Comparing the Top-Five and Bottom-Five-Ranked Football Academies in Norway
2021
Background: The aim of this study was to examine junior-elite football players’ perception of their talent development environment by comparing clubs ranked as the top-five and bottom-five in the 2017 Norwegian academy classification. Methods: In total, 92 male junior-elite football players recruited from under-19 teams from five professional football club academies took part in the study. The Talent Development Environment Questionnaire (TDEQ-5
Performance in dynamic movement tasks and occurrence of low back pain in youth floorball and basketball players
2020
Abstract Background Prospective studies investigating risk factors for low back pain (LBP) in youth athletes are limited. The aim of this prospective study was to investigate the association between hip-pelvic kinematics and vertical ground reaction force (vGRF) during landing tasks and LBP in youth floorball and basketball players. Methods Three-hundred-and-eighty-three Finnish youth female and male floorball and basketball players (mean age 15.7 ± 1.8) participated and were followed up on for 3 years. At the beginning of every study year the players were tested with a single-leg vertical drop jump (SLVDJ) and a vertical drop jump (VDJ). Hip-pelvic kinematics, measured as femur-pelvic angl…
Mechanical jumping power in young athletes.
1987
Mechanical jumping power was determined for 286 young male athletes representing six sports events and ranging in calendar and skeletal ages from 8.8 to 17.1 and from 7.8 to 18.1 years, respectively. The subjects performed successive maximal vertical jumps on a contact mat for 30 s. The number of jumps and their cumulative flight time after 15 and 30 s were used for calculations of mechanical power. The jumping performances of the young athletes were found to be reproducible from the age of 10-12 years in respect to the angular displacement of the knee and duration of contact. Absolute mechanical power, as well as power related to body weight, increased with calendar and skeletal ages. Of t…
The longer the better: Sleep–wake patterns during preparation of the World Rowing Junior Championships
2016
Recovery is essential for high athletic performance, and therefore especially sleep has been identified as a crucial source for physical and psychological well-being. However, due to early-morning trainings, which are general practice in many sports, athletes are likely to experience sleep restrictions. Therefore, this study investigated the sleep-wake patterns of 55 junior national rowers (17.7 ± 0.6 years) via sleep logs and actigraphy during a four-week training camp. Recovery and stress ratings were obtained every morning with the Short Recovery and Stress Scale on a 7-point Likert-type scale ranging from 0 (does not apply at all) to 6 (fully applies). The first training session was sch…
Kayaking performance is altered in mentally fatigued young elite athletes
2019
Background The present study aimed to assess the impact of 60 min of a cognitive demanding task inducing mental fatigue (Stroop) on kayaking performance in young elite athletes. The second objective was to elucidate the effect of mental fatigue on performance in a population of young under-17 elite athletes of national. Methods Thirteen under-17 elite kayakers completed 60 min of an incongruent Stroop color-word test, or the equivalent time in a control condition in a cross-over study design. Afterwards, participants completed a 2000 m kayaking time trial in which power output, stroke rate and time at the end of 400, 800, 1200, 1600 and 2000 m were recorded. Physiological and perceptual mea…
