Italy was one of the most impacted countries by the COVID-19 crisis, with detrimental effects on the world of sports. In this exploratory study, we examined Italian athletes' perceived stress and ...functional/dysfunctional psychobiosocial states during the COVID-19 crisis, comparing current assessment scores with data collected prior to the pandemic. Differences by gender, sport (i.e., individual vs team sport), and competitive level (elite/expert vs novice athletes) were also examined. The perceived stress scale and the psychobiosocial states scale were administered to 1132 competitive athletes about one month after the beginning of Italian lockdown. The comparison between the data collected during COVID-19 with the data collected before the pandemic outbreak revealed highly significant differences with medium to large effects sizes. Findings suggest that the COVID-19 crisis increased athletes' perceived stress and dysfunctional psychobiosocial states, while decreased functional psychobiosocial states. Analysis of variance revealed significant differences by gender on perceived stress and both types of psychobiosocial states, as well as by competitive level on perceived stress and functional psychobiosocial states. Specifically, women reported higher perceived stress and dysfunctional psychobiosocial states scores than men, and lower functional psychobiosocial states scores. Elite/expert athletes reported lower perceived stress and higher functional psychobiosocial states scores than novice athletes. From a practical point of view, training regimens and healthy behaviours during pandemic crises should be introduced as standard habits for health and well-being. The application of specific well-being protocols for women and novice athletes should be encouraged.
Mental health disorders (MHD) in elite athletes is a topic that has received increased attention in recent years. The overall aim of this position statement is to enhance awareness of this important ...topic and to critically discuss optimal service provision for athletes who suffer from MHD. In the first part of the paper a short overview of the research on MHD in elite athletes is provided. Elite athletes seem to have comparable prevalence rates for the most common MHD when compared to non-athletic peers, but there are still many disorders that have not been investigated in athletes. Sport specific situations such as injuries, periods of overtraining and career termination may put athletes at an increased risk of developing MHD. In the second part of the paper, models of service provision for elite athletes suffering from MHD from six European countries are presented, focusing on 1) professional service providers, 2) support systems, 3) diagnostic assessment, 4) clinical treatment, 5) performance during treatment, 6) screening, and 7) education systems. It emerges that competencies, certification issues, and professional boundaries of the involved service providers, as well as the structure of the National Health Care systems differ strongly across European countries, which makes defining a golden standard difficult. In the third part of this paper, the authors provide general recommendations for athletes and coaches, clubs, federations, organizations and scholars that hopefully will inspire stakeholders to optimize their support systems.
•Elite athletes have a similar prevalence rate of MHD as the normal population.•There is so far a lack of knowledge on how to support elite athletes with MHD.•Service provision for MHD vary greatly across European countries.•Recommendations for how to best support elite athlete with MHD are proposed.
Novel state-of-the-art amplifier and cap systems enable Electroencephalography (EEG) recording outside of stationary lab systems during physical exercise and body motion. However, extensive ...preparation time, cleaning and limited long-term stability of conventional gel-based electrode systems pose significant limitations in out-of-the-lab conditions. Dry electrode systems may contribute to rapid and repetitive mobile EEG acquisition with significantly reduced preparation time, reduced cleaning requirements and possible self-application by the volunteer but are known for higher channel failure probability and increased sensitivity to movement artefacts. We performed a counterbalanced repeated measure endurance cycling study to objectively validate the performance and applicability of a novel commercially available 64-channel dry electrode cap for sport science. A total of 17 healthy volunteers participated in the study, performing an endurance cycling paradigm comprising 5 phases: (I) baseline EEG, (II) pre-cycling EEG, (III) endurance cycling, (IV) active recovery, and (V) passive recovery. We compared the performance of the 64-channel dry electrode cap with a commercial gel-based cap system in terms of usability metrics, reliability and signal characteristics. Furthermore, we validated the performance of the dry cap during a realistic sport science investigation, verifying the hypothesis of a systematic, reproducible shift of the individual alpha peak (iAPF) induced by physical effort. The average preparation time of the dry cap was one third of the gel-based electrode caps. The average channel reliability of the dry cap varied between 80±15% (Phase I), 66±19% (Phase III), and 91±10% (Phase V). In comparison, the channel reliability of the gel-based cap varied between 95±3%, 85±9%, and 82±9%, respectively. No considerable differences were evident for the comfort evaluations nor the signal characteristics of both caps. A within-volunteers RM-ANOVA did not show significant effects of the electrode type on the iAPF (F(1,12)=1.670, p=0.221, ηp²=0.122, Power=0.222). However, a significant increase of the iAPF exists from Phase II to Phase IV and V due to exhaustive physical task. In conclusion, we demonstrated that dry electrode cap is equivalent to the gel-based electrode cap based on signal characteristics, comfort and signal information content thereby confirming the usefulness of dry electrodes in sports science and other mobile applications involving ample movement.
Pompa, D, Carson, HJ, Beato, M, di Fronso, S, and Bertollo, M. Attentional focus effects on lower-limb muscular strength in athletes: A systematic review. J Strength Cond Res 38(2): 419-434, ...2024-Evidence links an athlete's focus of attention to enhancing strength performance. However, additional research is needed to investigate the applicability of studies beyond the tasks and population currently examined. Therefore, we aimed to systematically review studies concerning attentional focus effects on strength characteristics on lower-limb tasks in athletes. Scopus, Web of Science, and EBSCO databases were searched using PRISMA PERSIST guidelines and keywords related to the focus of attention, force production processes, and athletes. Subjects were categorized: world class (tier 5); elite (tier 4); highly trained (tier 3); trained/developmental (tier 2); nonathletes (tiers 1-0); and mixed (different levels). Fifteen of 296 studies met the inclusion criteria. Included studies investigated the focus of attention effects on performance ( n = 6), between skill levels ( n = 2), and for learning ( n = 5), with respect to subject preference ( n = 1); one study did not state the aim. Studies achieved an average risk of bias score of "excellent"; however, findings suffered in the assessment of certainty. Only 2 studies reported an advantage for one type of attentional focus (external focus) across conditions ( g = 0.13-0.42) with tier 2 and mixed tier athletes. Research does not address the needs of elite athletes, and there is limited evidence on each type of strength characteristics and muscle action. There is also a need to incorporate methodological steps to promote task-relevant instructions. Research should focus on contextualized information within professional practice to offer stronger translational implications for athletes and coaches.
The central nervous system seems to have an important role in fatigue and exercise tolerance. Novel noninvasive techniques of neuromodulation can provide insights on the relationship between brain ...function and exercise performance. The purpose of this study was to determine the effects of transcranial direct current stimulation (tDCS) on physical performance and physiological and perceptual variables with regard to fatigue and exercise tolerance. Eleven physically active subjects participated in an incremental test on a cycle simulator to define peak power output. During 3 visits, the subjects experienced 3 stimulation conditions (anodal, cathodal, or sham tDCS-with an interval of at least 48 h between conditions) in a randomized, counterbalanced order to measure the effects of tDCS on time to exhaustion at 80% of peak power. Stimulation was administered before each test over 13 min at a current intensity of 2.0 mA. In each session, the Brunel Mood State questionnaire was given twice: after stimulation and after the time-to-exhaustion test. Further, during the tests, the electromyographic activity of the vastus lateralis and rectus femoris muscles, perceived exertion, and heart rate were recorded. RM-ANOVA showed that the subjects performed better during anodal primary motor cortex stimulation (491 ± 100 s) compared with cathodal stimulation (443 ± 11 s) and sham (407 ± 69 s). No significant difference was observed between the cathodal and sham conditions. The effect sizes confirmed the greater effect of anodal M1 tDCS (anodal x cathodal = 0.47; anodal x sham = 0.77; and cathodal x sham = 0.29). Magnitude-based inference suggested the anodal condition to be positive versus the cathodal and sham conditions. There were no differences among the three stimulation conditions in RPE (p = 0.07) or heart rate (p = 0.73). However, as hypothesized, RM- ANOVA revealed a main effect of time for the two variables (RPE and HR: p < 0.001). EMG activity also did not differ during the test accross the different conditions. We conclude that anodal tDCS increases exercise tolerance in a cycling-based, constant-load exercise test, performed at 80% of peak power. Performance was enhanced in the absence of changes in physiological and perceptual variables.
Various methods have been employed to investigate different aspects of the brain activity modulation related to the performance of a cycling task. In our study we examined how functional connectivity ...and brain network efficiency varied during an endurance cycling task. To this purpose, we reconstructed EEG signals at source level: we computed current densities in 28 anatomical regions of interest (ROIs) through the eLORETA algorithm, then we calculated the Lagged Coherence of the 28 current density signals to define the adjacency matrix. To quantify changes of functional network efficiency during an exhaustive cycling task, we computed three graph theoretical indices: local efficiency (LE), global efficiency (GE) and Density (D) in two different frequency bands, Alpha and Beta bands, that indicate alertness processes and motor binding/fatigue respectively. This analysis was conducted for six different task intervals: pre-cycling, initial, intermediate and final stages of cycling, active recovery and passive recovery. Fourteen participants performed an incremental cycling task with simultaneous EEG recording and RPE monitoring to detect participants’ exhaustion. LE remained constant during the endurance cycling task in both bands. Therefore, we speculate that fatigue processes did not affect segregated neural processing. We observed an increase of GE in the Alpha band only during cycling, that could be due to greater alertness processes and preparedness to stimuli during exercise. Conversely, although D did not change significantly over time in the Alpha band, its general reduction in the Beta bands during cycling could be interpreted within the framework of the neural efficiency hypothesis, which posits a reduced neural activity for expert/automated performances. We argue that the use of graph theoretical indices represents a clear methodological advancement in studying endurance performance.
Background
The COVID-19 pandemic impacted on the sporting field, with athletes constrained in home isolation without the possibility to train and compete in their usual environments. This situation ...has been investigated within the theoretical frameworks of athletic identity and cognitive emotion regulation.
Objectives
The objectives of our investigation were to: (a) validate the athletic identity measurement scale (AIMS) for use in Italian language; and (b) explore differences by gender, typology of sport (individual vs. team), and competitive level (elite vs. non-elite) in athletic identity and in cognitive emotion regulation during the Covid-19 lockdown period.
Methods
To achieve these objectives, the reliability and construct validity of the Italian version of the AIMS have been tested in Study
1
. Multivariate and univariate analyses were run to evaluate differences between different groups of athletes in Study
2
.
Results
Results from Study
1
suggest a 3-factor higher order model of athletic identity. Results from Study
2
highlight that, during this lockdown period, elite athletes and team sports athletes show higher athletic identity. Cognitive emotion regulation strategies are different for gender and for competitive level. Finally, athletes with higher athletic identity tend to ruminate and catastrophize more.
Conclusions
The present multi-study paper contributes to the theoretical field with a validated measure of athletic identity in Italian language. It also provides some practical implications that could apply in this situation of isolation and can be extended to cases such as those of injury or illness.
