Environmental Conditions, Air Pollutants, and Airways

2019

Air pollution is a major problem worldwide, which could be even more serious for athletes who train in urban environments. Exercise increases minute ventilation and exposure to pollutants, but the literature on the effects of air pollution in athletes is relatively scarce, with the exception of chlorine exposure in athletes of aquatic sports and air pollution secondary to ice resurfacing in athletes performing in ice arenas. Although air pollution may exert detrimental effects on athletic performance, little has been published on this topic. The largest body of information regards the impact of air pollution during urban active transport, i.e., walking and cycling in cities, due to the pote…

The Development of the Brief Eating Disorder in Athletes Questionnaire

2014

MARTINSEN, M., I. HOLME, A. M. PENSGAARD, M. K. TORSTVEIT, and J. SUNDGOT-BORGEN. The Development of the Brief Eating Disorder in Athletes Questionnaire. Med. Sci. Sports Exerc., Vol. 46, No. 8, pp. 1666–1675, 2014. Purpose: The objective of this study is to design and validate a brief questionnaire able to discriminate between female elite athletes with and without an eating disorder (ED). Methods: In phase I, 221 (89.5%) adolescent athletes participated in a screening including the Eating Disorder Inventory-2 (EDI2) and questions related to ED. All athletes reporting symptoms associated with ED (n = 96, 94.1%) and a random sample without symptoms (n = 88, 86.3%) attended the ED Examinatio…

Athletes’ regulation of emotions experienced during competition: A naturalistic video-assisted study.

2015

This study aimed to identify the type and effectiveness of emotional regulation strategies used by table tennis players to manage their emotions experienced during competition. Using a naturalistic video-assisted approach, 30 interviews were conducted with 11 national table tennis players. Ten emotions were identified in the participants’ transcriptions: anger, anxiety, discouragement, disappointment, disgust, joy, serenity, relief, hope, and pride. Qualitative analyses of participants’ transcriptions revealed the emergence of 4 categories pertaining to emotion regulation: (a) regulation efforts comprising: (i) antecedent-focused regulation (e.g., attention deployment, cognitive change); (i…

Convolutional Neural Network-Based Human Movement Recognition Algorithm in Sports Analysis

2021

In order to analyse the sports psychology of athletes and to identify the psychology of athletes in their movements, a human action recognition (HAR) algorithm has been designed in this study. First, a HAR model is established based on the convolutional neural network (CNN) to classify the current action state by analysing the action information of a task in the collected videos. Secondly, the psychology of basketball players displaying fake actions during the offensive and defensive process is investigated by combining with related sports psychological theories. Then, the psychology of athletes is also analysed through the collected videos, so as to predict the next response action of the …

Cultural sport psychology: a critical review of empirical advances

2016

Despite a long standing assertion that sociocultural domain is one of the factors constituting human psychological phenomena, sport psychological science has only recently begun to examine culture as the principal basis of physical activity and sport participants’ behaviour, wellbeing, engagement, and performance outcomes. Emphasizing the centrality of culture in bringing meaning to athlete careers and life projects, I summarise empirical literature explicitly positioned within cultural sport psychology (CSP). Specifically, I focus on two areas of psychological inquiry – acculturation and athletic career – in which the CSP theoretical tenets and agenda stimulated emergence of novel research…

Translation and Reliability of the Preliminary Spanish Version of the Sport Imagery Questionnaire

2012

The purpose of this study was to examine the reliability of the preliminary Spanish version of the Sport Imagery Questionnaire (SIQ). The SIQ was developed to examine five cognitive and motivational functions of imagery use. Participants were 81 athletes competing in soccer (n = 43) and roller skating (n = 38), ranging in age from 14 to 29 years (M = 18.10, SD = 3.16). Reliability was evaluated through internal consistency analyses of the scale. Cronbach’s alpha coefficients were high indicating that the scale is a reliable instrument for the measurement of imagery use in Spanish athletes. Further psychometric research should now examine factor structure and imagery use across competitive l…

2019

Despite the general consensus regarding the implementation of self-report measures in the training monitoring, there is a lack of research about their applicability and comprehensibility among developing athletes. However, this target group needs special considerations to manage the increasing training demands while maintaining health and performance. This study deals with challenges of applying recovery-stress questionnaires which were validated with adult populations among developing athletes and presents a possible approach to enhance their applicability. In two phases, the Acute Recovery and Stress Scale (ARSS), a 32-adjective list covering eight scales, and the 8-item derived version, …

Psychomotor and Motor Speed in Power Athletes Self-Administering Testosterone and Anabolic Steroids

1988

Abstract The effect of self-administered testosterone and anabolic steroids on psychomotor and motor speed were studied among five top-level power athletes. The experiment included a 26-week intensive strength training period in association with the use of exogenous hormones and a 6-week follow-up after drug withdrawal. Six athletes not using exogenous hormones served as a control group. The results indicated a similar, and in most cases insignificant, improvement (0–10%) in performance in both groups in both the simple and more complicated motor and psychomotor tests. Only in maximal vertical speed related to body weight was there more improvement in the experimental group, from 122.2 to 1…

The Acute Effect of Low Intensity Aerobic Exercise on Psychomotor Performance of Athletes with Nocturnal Sleep Deprivation

2018

Objectives: Psychomotor performance is a vital factor which decisively affects the athletic performance. The purpose of the research was to investigate the acute effects of low intensity aerobic exercise on psychomotor performance of athletes with nocturnal sleep deprivation. Methods: Sixteen professional female volleyball players with mean age of 22.3 ± 2.6 years old were studied twice in a balanced, randomized design. The participants were asked to fill the Pittsburgh sleep quality index (PSQI) prior to the beginning of the study and their nocturnal activity was recorded at 1-minute intervals and scored with the Actiwatch sleep analysis. The study used the Vienna Test System to measure co…
