Psychological and behavioural factors of unintentional doping: A preliminary systematic review

2018

In some cases, doping in sport is an intentional goal-directed behaviour, but research suggests that it might also occur accidentally when athletes inadvertently or unintentionally consume banned performance-enhancing drugs via food, supplements, or medication. Because research into the psychological factors of unintentional doping is still emerging, this paper aims to conduct a preliminary systematic review of all the existing literature concerning the psychology of unintentional doping in sport. The systematic review was carried out via an extensive search of Medline, PsycINFO, PsycTESTS, PsycARTICLES, and Web of Science, and reports from World Anti-Doping Agency. Among the 2110 articles …

‘I was excited to train, so I didn’t have problems with the coach’: dual career athletes’ experiences of (dis)empowering motivational climates

2019

In addition to investing in athletic development, adolescent elite athletes are expected to complete their secondary education. As a result of this expectation and the demands of sport and education, they may struggle to sustain high levels of motivation for both domains. Grounded in theoretical tenets of empowering coaching, this study sought to explore student–athletes’ perceptions of empowering and disempowering motivational climates and their possible implications for athletes’ dual career experiences. Semi-structured interviews were conducted with 17 Finnish student–athletes, and the data were thematically analysed. The analysis indicated that a majority of the athletes had experiences…

Exploring the Life Form of a Student Athlete Afforded by a Dual Career Development Environment in Finland

2020

The current paper introduces a case study conducted in one of the most well-established athletic talent development environments in Finland, with the focus on the environment’s ecological dynamics and organizational culture, in light of its recent effort to rebrand itself as a dual career development environment. Our analysis has been inspired by the holistic ecological approach and ecological dynamics, wherein the authors have considered a dual career development environment from the point of view of its transactions with agentic individuals and affordances for student athletes in the study domain, the sports domain, and the private domain. The authors believe our findings can provide othe…

The Relationship between Motivational Climate and Personal Treatment Satisfaction among Young Soccer Players in Norway: The Moderating Role of Suppor…

2020

Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study&rsquo

Validity and Reliability of a New Optoelectronic System for Measuring Active Range of Motion of Upper Limb Joints in Asymptomatic and Symptomatic Sub…

2019

The aim of this study was to evaluate the validity of the Veloflex infrared dynamic angle-meter (Veloflex-IDA) and the intra- and inter-rater reliability when measuring the ranges of motion (ROMs) of the upper limb joints. Thirty-five healthy and 20 symptomatic participants were evaluated. Twelve upper limb movements were measured in two sessions with the Veloflex-IDA, which is a device composed of a camera that tracks the trajectory of retro-reflective markers. In addition, a goniometer was used in the first session to evaluate concurrent validity. Validity and agreement were evaluated by Pearson correlation coefficient (r) and Bland&ndash

Predictive Strength of Physical Education-Centered Physical Literacy Indicators on Physical Activity

2021

This study examined the predictive strength of selected physical education (PE)-centered physical literacy indicators on elementary school students’ accelerometer-measured moderate to vigorous intensity physical activity (PA). The study was a cross-sectional study with a sample of 450 Finnish children (M = 11.26 [0.32]; nfemales = 194; nmales = 256). Data on a set of predictor variables (motor competence, in-class PE moderate- to vigorous-intensity PA [MVPA], health-related fitness, and PE motivation and enjoyment) and total MVPA as a single outcome variable were collected. The entire model explained almost 30% of MVPA (R2adj = .298). Cardiorespiratory endurance (β = 0.42, 95% confidence in…

Finnish students’ enjoyment and anxiety levels during fitness testing classes

2020

Background: Fitness testing is a commonly applied learning and teaching practice implemented in both secondary and elementary school physical education (PE). Many teachers believe that by using a variety of different tests, they are able to provide students with feedback regarding their fitness status, and furthermore, increase students’ willingness to be physically active later in their lives. However, empirical evidence concerning students’ affective responses during fitness testing classes is limited. Purpose: The primary aim of the study was to investigate whether students’ perceptions of enjoyment and anxiety differed between two different types of fitness testing classes and PE in gen…

2020

The objective of this study was to analyze the associations of various individual- and environmental-related factors with subgroups of daily, frequent, moderate and low moderate-to-vigorous physical activity (MVPA) among children and adolescents. Data were obtained from the Finnish School-age Physical Activity (FSPA) study 2016 from 4677 national representative 11-, 13-, and 15-year-old children and adolescents. MVPA and individual- and environmental-related factors were assessed by a questionnaire and analyzed by two-level logistic regression. Seventeen of the twenty-one variables were statistically significantly associated with MVPA. However, only three variables were statistically signif…

Cross-sectional association between active commuting and perceived commuting stress in Austrian adults: Results from the HOTway study

2020

Abstract Objective Little is known about the acute psychological stress responses caused by commuting. Evidence for the benefits of active commuting (e.g., walking, cycling) is usually based on studies without measurements in free-living environments and without consideration of daily variations in stress. This study investigated the association between commuting mode (active, passive) and perceived commuting stress, assessed on multiple days immediately after commuting. Methods Adults participating in the cross-sectional ‘Healthy On The way’ (HOTway) study between 2016 and 2017 in Graz, Austria, were included. Participants completed an online survey and responded to statements about percei…

Effects of marathon fatigue on running kinematics and economy

2007

International audience; The influence of marathon fatigue on both running kinematics and economy was investigated with 8 subjects. The measurements included a treadmill test at 3 steady submaximal speeds performed before and after the marathon. One complete left leg cycle was videotaped at 100 Hz from the left side at each speed. The analysis included contact time (braking and push-off') and flight time as well as displacements and angular velocities of the left hip and knee. This analysis was complemented by the measurements of the electromyographic (EMG) activity of the gastrocnemius muscle at each running velocity, and energy expenditure (E) of the last 30.s at the 2 slowest speeds. The …
