Exercise-induced bronchospasm among athletes in Lower Silesia Province

Abstract

A few studies have reported data on the prevalence of exercise-induced bronchospasm in high school and university athletes. Recently published data suggest that exercise-induced bronchospasm may affect up to 39% of American university athletes. To date, no data describing this pathology in athletes from Central Europe have been published. The aim of the present study was to establish the prevalence of exercise-induced bronchospasm in pupils attending sports mastership classes in secondary school as well as students of the University of Physical Education in Wroclaw. The participants were 77 athletes (30 women and 47 men) aged 16–27 years (mean 17.3 years). Only one athlete (1.29%) diagnosed with atopic asthma before testing experienced a fall in forced expiratory volume in one second (12.9% FEV₁) compared with baseline, which showed that the exercise test result was positive. From a clinical point of view, the ventilation disturbance was asymptomatic. In the other participants, there were slight but statistically significant rises in FEV₁ (P < 0.02). The results of our study indicate a very low prevalence of exercise-induced bronchospasm in the population of athletes examined.     

Sports Betting and Other Gambling in Athletes,Fans, and Other College Students

Gambling on college and professional sports and the influence of attending colleges with differing levels of “sports interest” were examined among athletes, sports fans, and other students (N = 10,559) at 119 colleges in the United States using multilevel statistical analysis. Athletes and fans reported more sports gambling compared to other students, with no differences between athletes and fans. Male students were more likely to gamble than female students, but gender did not moderate the relationship between athletic participation and sports gambling. Students attending schools with a greater “sports interest” were more likely to gamble on college sports after adjusting for individual characteristics. Athletes, sports fans, and students attending schools with high “sports interest” are appropriate targets for prevention efforts.

Food attitudes in female athletes: Association with menstrualcycle length

Abstract

The aim of this study was to examine the relationship between indicators of risk of disordered eating, body image and varied menstrual cycle lengths. Altogether, 151 female athletes were invited from 16 sports and 70 female non-athletic controls were recruited from a university lecture class. The participants completed several surveys, including demographics, menstrual cycle history, physical activity, Eating Disorder Inventory (EDI) and the Three Factor Eating Questionnaire (TFEQ). Selected EDI subscales were summed to reflect eating disorder risk and body image. Menstrual cyclicity was based on self-reported cycle length for the last 6 months (normal cycles = 26–32 days, irregular cycles = <26 or >32 days). Athletes overall had more irregular cycles (29.1%) than the non-athletes (15.7%) (P < 0.05). There were significant differences in scores for eating disorder risk, body dissatisfaction, drive for thinness, cognitive restraint (TFEQ) and disinhibition (TFEQ), only when athletes were divided based on menstrual cyclicity (i.e. irregularly cycling athletes had higher scores than athletes with normal menstrual cycle lengths). No differences in these scores were found between non-athletes with normal or irregular menstrual cycle lengths. In conclusion, irregularly short or long menstrual cycle length is associated with subtle indications of higher risk of disordered eating in female athletes.     

Generations: Academic and Athletic Integration of a Southern PWI Basketball Program

Purpose: The purposes of this study were to: (a) analyze the insights and experiences of the 1st African American student-athlete (in basketball) at a prominent predominantly White institution in the Deep South as well as the later insights and experiences of his sons at the same university; and (b) to present a counterstory to the dominant historical rendering of the Civil Rights Movement, the integration of athletics, and the experiences and outcomes of contemporary African American athletes. Method: Using qualitative critical race methodology, investigators conducted and analyzed interviews with the 1st African American to play basketball at a prominent university located in the Deep South and his 2 sons who attended the same university a generation later. Results: Using the lens of critical race theory, the themes conceived from the analysis were the counterstory of agency, counterstorytelling stereotypes, and the salience of everyday racism. Conclusion: Racism is still existent within society, even within college athletics. The holistic success of African American athletes in college is dependent upon their ability to navigate overt and covert racial climates.     

Parental Behavior,Cognitive Appraisal,and Motivation in Young Athletes

Purpose: This study tested two hypotheses relating young athletes’ sports motivations to parental behaviors and cognitive appraisal: (1) young athletes’ motivation in sports is related to their parents’ behavior; and (2) this relationship is mediated by cognitive appraisal, even after controlling for competitive level and sports records. Method: This cross-sectional study included 673 young athletes and it measured the athletes’ perceptions of parental behaviors, cognitive appraisal, and sports motivation. Results: Structural equation modeling confirmed Hypothesis 1–the mother’s behaviors accounted for 15 to 16% of the variance in sports motivation, and the father’s behaviors accounted for 12 to 21% of the variance. The correlation patterns differed according to whether the athletes were evaluating the mother’s or father’s behaviors. Hypothesis 2 also was confirmed, for cognitive appraisal partially mediated the relationship between the perception of parental behaviors and sports motivation (34% of the variance was accounted for by the perception of the mother’s behavior; 30% by the father’s). The mediating model did not vary with competitive level or sports records. Conclusion: Parental behaviors and cognitive appraisal need to be taken into account to understand young athletes’ sports motivations.     

Risk and protective factors for mental health in elite athletes: a scoping review

ABSTRACT

The purpose of this scoping review was to provide an overview of studies concerning the mental health (MH) of elite athletes and to provide a methodological, conceptual, and applied overview of factors affecting elite athletes’ MH. A total of nine reviews and 43 empirical studies were evaluated and are reported in three sections: sample characteristics, research design, and factors affecting elite athletes’ MH. These factors were grouped into risk and protective factors and divided into a personal and sport-environmental domain. The studies used quantitative (84%), qualitative (11%), and mixed-method (5%) designs and examined a wide range of sports in different countries. Our review shows that researchers have predominantly examined the prevalence of athletes’ mental ill-health (e.g. depression) and the related factors compromising MH. Potential protective factors such as the feeling of autonomy, positive relations in sport and private life, and adequate recovery were highlighted in the qualitative studies. The discussion appraises the findings through a critical lens, focuses on the current state of the research area and the MH definition, limitations, suggested practical implications (e.g. to provide MH literacy to both athletes and coaches), and future research directions (e.g. examining environments that foster elite athletes’ MH).     

Sleep/wake behaviours of elite athletes from individual and team sports

Abstract

Sleep is an essential component for athlete recovery due to its physiological and psychological restorative effects, yet few studies have explored the habitual sleep/wake behaviour of elite athletes. The aims of the present study were to investigate the habitual sleep/wake behaviour of elite athletes, and to compare the differences in sleep between athletes from individual and team sports. A total of 124 (104 male, 20 female) elite athletes (mean ± s: age 22.2 ± 3.0 years) from five individual sports and four team sports participated in this study. Participants' sleep/wake behaviour was assessed using self-report sleep diaries and wrist activity monitors for a minimum of seven nights (range 7–28 nights) during a typical training phase. Mixed-effects analyses of variances were conducted to compare the differences in the sleep/wake behaviour of athletes from two sport types (i.e. individual and team). Overall, this sample of athletes went to bed at 22:59 ± 1.3, woke up at 07:15 ± 1.2 and obtained 6.8 ± 1.1 h of sleep per night. Athletes from individual sports went to bed earlier, woke up earlier and obtained less sleep (individual vs team; 6.5 vs 7.0 h) than athletes from team sports. These data indicate that athletes obtain well below the recommended 8 h of sleep per night, with shorter sleep durations existing among athletes from individual sports.

Elite athletes' attitudes towards the use of placebo-induced performance enhancement in sports

Abstract

While an increasing number of research is devoted to the understanding of placebo effects in sports, athletes' experiences with and attitudes towards the use of placebo for performance enhancement remain poorly understood. In this study, 79 elite athletes from different sports were surveyed on five issues related to placebo use in sports. Results showed that 47% of the athletes have experienced placebo effects in the past. A majority of the athletes (82%) thought that placebos could affect their sports performances. A wider use of placebos in sport settings was endorsed more by those who have experienced placebo effects in the past than those who did not (P = .005). Regardless of past experience with placebo, more than half of the athletes (53%) would accept an unknown but legitimate substance from the coach, and 67% of them would not mind a placebo-linked deception if that was effective. These findings confirm that most elite athletes believe in the power of placebos in enhancing sports performance, and those having a positive past experience exhibit slightly more favourable attitudes in contrast to those without such experiences.     

Chronic participation in externally paced,but not self-paced sports is associated with the modulation of domain-general cognition

Abstract

The present study investigated the role of chronic sport participation in the modulation of vigilance and inhibitory control. We also aimed to disentangle the relative contribution of different types of sport expertise and sport-related fitness to the exercise-cognition relationship. Three groups of young adults differing in their chronic sport expertise (externally-paced sports, n?=?22, self-paced sports, n?=?22, non-athletes, n?=?22) took part in the study. Participants completed a cardiovascular fitness test, a hand-eye coordination test and two different types of vigilance tasks: (1) Psychomotor Vigilance Task (PVT) and (2) Oddball Task, which were designed to gain insight into the cognitive processes involved in sustaining attention over time and allocating selective attention by exerting inhibitory control, respectively. No differences were found in PVT performance between the two athlete groups and between self-paced sports athletes and non-athletes, whereas athletes from externally-paced sports outperformed non-athletes. Crucially, athletes from externally-paced sports also differed from those of self-paced sports and non-athletes in the Oddball task, showing less omission and commission errors. The sport expertise effect was independent of participant’s cardiovascular fitness while hand-eye coordination modulated vigilance and inhibitory control performance. Our findings add novel empirical evidence to the role of expertise in cognitively demanding sports as an important factor in the relationship between exercise and cognition.     

Gender differences in the perceived impact that athlete leaders have on team member emotional states

ABSTRACT

Emotional contagion has been recognized as a variable influencing individual behaviour and team functioning. In particular, leaders within the team have been suggested to have a significant impact on their teammates through the expression of their emotions. As a result, the aim of this study was to provide greater insight into how different athlete leaders impact the emotional state of their team members, and whether gender differences existed in these relationships. Participants were 295 university student-athletes (200 male and 95 female) recruited from four universities in the UK. Data were collected in a two-step process. First, a voting/rating procedure was conducted within team to identify dominant task, motivational, social and external leaders. Then, participants completed the emotional contagion subscale of the Measure of Empathetic Tendency to rate the impact different athlete leaders had upon their emotional state. A MANOVA was conducted to explore gender differences in reported emotional susceptibility by leadership role. Subsequent ANOVAs highlighted significant differences between leadership role scores for female participants only. The results suggest that female athletes are more susceptible to emotional influence than male athletes. Furthermore, female athletes experienced a greater variation in the perceived emotional influence of different leadership roles in the team.     

Refinement of saliva microRNA biomarkers for sports-related concussion

BackgroundRecognizing sport-related concussion (SRC) is challenging and relies heavily on subjective symptom reports. An objective, biological marker could improve recognition and understanding of SRC. There is emerging evidence that salivary micro-ribonucleic acids (miRNAs) may serve as biomarkers of concussion; however, it remains unclear whether concussion-related miRNAs are impacted by exercise. We sought to determine whether 40 miRNAs previously implicated in concussion pathophysiology were affected by participation in a variety of contact and non-contact sports. Our goal was to refine a miRNA-based tool capable of identifying athletes with SRC without the confounding effects of exercise.MethodsThis case-control study harmonized data from concussed and non-concussed athletes recruited across 10 sites. Levels of salivary miRNAs within 455 samples from 314 individuals were measured with RNA sequencing. Within-subjects testing was used to identify and exclude miRNAs that changed with either (a) a single episode of exercise (166 samples from 83 individuals) or (b) season-long participation in contact sports (212 samples from 106 individuals). The miRNAs that were not impacted by exercise were interrogated for SRC diagnostic utility using logistic regression (172 samples from 75 concussed and 97 non-concussed individuals).ResultsTwo miRNAs (miR-532-5p and miR-182-5p) decreased (adjusted p < 0.05) after a single episode of exercise, and 1 miRNA (miR-4510) increased only after contact sports participation. Twenty-three miRNAs changed at the end of a contact sports season. Two of these miRNAs (miR-26b-3p and miR-29c-3p) were associated (R > 0.50; adjusted p < 0.05) with the number of head impacts sustained in a single football practice. Among the 15 miRNAs not confounded by exercise or season-long contact sports participation, 11 demonstrated a significant difference (adjusted p < 0.05) between concussed and non-concussed participants, and 6 displayed moderate ability (area under curve > 0.70) to identify concussion. A single ratio (miR-27a-5p/miR-30a-3p) displayed the highest accuracy (AUC = 0.810, sensitivity = 82.4%, specificity = 73.3%) for differentiating concussed and non-concussed participants. Accuracy did not differ between participants with SRC and non-SRC (z = 0.5, p = 0.60).ConclusionSalivary miRNA levels may accurately identify SRC when not confounded by exercise. Refinement of this approach in a large cohort of athletes could eventually lead to a non-invasive, sideline adjunct for SRC assessment.     

Personality and Intelligence Characteristics of Selected High School Athletes and Nonathletes

Abstract

Selected high school athletes (junior and senior lettermen in baseball, basketball, football, swimming, and wrestling) were compared with nonathletes from the same population for differences in selected profile scales, as indicated by the Minnesota Multiphasic Personality Inventory (MMPI), and intelligent quotients (I).

Personality characteristics in terms of MMPI categories of hypochondriasis (Hs), depression (D), hysteria (hy), psychopathic deviation (Pd), femininity (Mf), paranoia (Pa), and psychasthenia (Pt) distinguished betweeen athletic and nonathletic groups. Femininity and intelligence were significantly lower for all athletic groups when compared with the nonathletic group. Hypochondriasis was significantly higher for all athletic groups, except swimmers, when compared with the nonathletic group. Only hypomania (Ma) and the validity scale (K) failed to differentiate between athletic and nonathletic groups.     

Sport,how people choose it: A network analysis approach

Abstract

In order to investigate the behaviour of athletes in choosing sports, we analyse data from part of the We-Sport^® database, a vertical social network that links athletes through sports. In particular, we explore connections between people sharing common sports and the role of age and gender by applying “network science” approaches and methods. The results show a disassortative tendency of athletes in choosing sports, a negative correlation between age and number of chosen sports and a positive correlation between age of connected athletes. Some interesting patterns of connection between age classes are depicted. In addition, we propose a method to classify sports, based on the analyses of the behaviour of people practising them. Thanks to this brand new classifications, we highlight the links of class of sports and their unexpected features. We emphasise some gender dependency affinity in choosing sport classes.     

Personality Traits of Women in Team Sports vs. Women in Individual Sports

Abstract

The problem under investigation was to determine if were distinguishing personality traits when women who compete in team sports were compared to women who compete in individual sports. The subjects were chosen from a selected group of 156 women AAU athletes and the 1964 United States Olympic team. Those women who agreed to take part in the study were sent a copy of Form A of the Sixteen Personality Factor Questionnaire, which was the instrument used to measure selected personality factors. Differences between groups were analyzed by means of the t test.

The results indicated that women athletes who compete in individual sports rated higher on the personality factors of dominance, adventurousness, sensitivity, introversion, radicalism, and self-sufficiency and lower on the factor of sophistication when compared to women athletes who compete in team sports. No differences were found in the factors of sociability, intelligence, stability, surgency, conscientiousness, suspecting, guilt-proneness, high self-sentiment, or high ergic tension.
