Meaning in elite sport – A narrative review of scholarship in sport psychology
No full textIntroduction
Athletes’ heart-felt stories about their experiences in elite sport almost naturally evoke the notion of meaning. However, although various scholars and practitioners have suggested the concept of meaning to the sport psychology audience in the past two decades (e.g., Beckmann, 2023; Ravizza, 2002; Ronkainen & Nesti, 2020), its study in this discipline is still in the early stages compared to established psychological scholarship on the topic. To promote meaning as a complementary lens for research and applied work in sport psychology, the presentation aims to introduce the concept informed by psychological inquiry, and to synthesize and critically comment on the extant scholarship. For this, the wider meaning in life literature will be drawn on to give an overview of components, sources, pathways, and qualities of meaning and set it apart from the related concept of purpose.
Methods
A narrative review of 15 studies on meaning (n = 10) and purpose (n = 5) from elite sport contexts was conducted.
Results
The scholarship on meaning and purpose in elite sport revealed itself diverse in terms of employed study designs (quantitative, qualitative), methodologies and theoretical frameworks (e.g., narrative inquiry, phenomenology), conceptualizations of meaning and purpose (e.g., existential meaning, purpose in coaching), interpretations of meaning (intrapsychic or relational), and topics researched in relation to it (e.g., forced migration, injury experiences). To date the literature base on meaning and purpose in elite sport is characterized by fragmentation and largely imprecise use of the concept.
Discussion/Conclusion
To assist future empirical research and increase conceptual clarity of meaning in elite sport, sport psychology should integrate knowledge from its parent discipline psychology. Additionally, to make the somewhat abstract notion of meaning tangible for sport practitioners, more applied questions must be addressed. Through this, meaning could offer a truly holistic approach to well-being and mental health research and practice in sport. Importantly, “working” with meaning requires personal positioning, since conceiving of meaning as performance enhancement tool or as existential concern has major implications for how it is investigated and for how or whether it should be increased.

Unveiling the shadows - Substance use among para-athletes: A qualitative study with Swiss elite para-athletes
No full textBackground
Despite the growth of para-sport, little research has been conducted on psychotropic substance use among Swiss elite para-athletes (McDuff et al., 2019; Rice et al., 2016; Weber et al., 2022). This study is among the first to explore this under-researched area, focusing on athletes’ perceptions and mental health concerns related to substance use.
Methodology
Adopting a qualitative research design, this study conducted semi-structured interviews with fifteen (N = 15) active Swiss adult elite para-athletes from nine different summer and winter sports. Thematic analysis was employed to interpret the interview data, focusing on athletes\u27 perceptions and experiences related to substance use (Guest et al., 2012).
Findings
On the one hand, an increase in athletic level and professionalisation seem to leave little room for the use of substances that could be detrimental to athletic performance. On the other hand, the results suggest that stress, negative emotions, physical pain, and a background of substance use may be positively associated with substance use in elite para-athletes (Lardi et al., in preparation).
Conclusion
The findings suggest a need for targeted interventions and support systems within athletic federations. Proposed measures include the development of comprehensive prevention strategies, regulatory frameworks, and treatment programs tailored to the unique needs of para-athletes. This study contributes valuable insights into substance use among Swiss elite para-athletes, advocating for specialized interventions to support athlete well-being.

Brain-IT: Targeting the brain using information technology for secondary prevention of mild neurocognitive disorder
No full textIntroduction
A collaborative international guideline recommends physical exercise (PE) for the secondary prevention of mild neurocognitive disorder (mNCD; Veronese et al., 2023). PE is proposed to promote brain plasticity, maintain or increase cognitive reserve, and alleviate the pathological state in individuals with mNCD, which is characterized by an abnormal accumulation of proteins, excessive oxidative stress, metabolic disorder, and neuroinflammation within the brain (Lu et al., 2023). Individuals with mNCD often also have disrupted self-regulatory capacity to flexibly adapt to daily life challenges. This capacity is supported by the central autonomic network (CAN), which can be viewed as an integrated component of an internal regulatory system in which the brain controls visceromotor, neuroendocrine, and behavioral responses that are critical for goal-directed behavior, adaptability, and health (Thayer, 2009). To maximize the effectiveness of secondary prevention of mNCD, interventions should be designed to also target this network specifically. This could be achieved by combining motor-cognitive training with resonance breathing guided by heart rate variability biofeedback (HRV-BF). HRV-BF training aims to increase cardiac autonomic control, enhance homeostatic regulation, and regulate emotional state. It is effective in improving cardiac autonomic control, cognitive functioning (in particular executive functions), and emotional regulation (i.e., by decreasing symptoms of depression, anxiety, and stress) across different age groups and clinical populations (Laborde et al., 2022; Lehrer et al., 2020). Evidence also supports a causal role of cardiac autonomic control in modulating plasma Alzheimer’s disease-related biomarkers (Min et al., 2023). Although HRV-BF has been suggested as a complementary treatment (Lehrer et al., 2020), its combination with motor-cognitive training remains to be investigated.
Methods
We systematically designed, developed, and evaluated a novel training concept (called ‘Brain-IT’) specifically for older adults with mNCD. It addresses the mechanism of action described above. The projects’ methodology (Manser & de Bruin, 2021) followed the guidelines of the Medical Research Council for the development and evaluation of complex interventions as well as the Multidisciplinary Iterative Design of Exergames (MIDE) - Framework. The Brain-IT project was structured in three phases. In phase 1, we systematically combined a comprehensive literature synthesis (Manser & de Bruin, 2021) with qualitative research including primary end users (older adults with mNCD), secondary end users (physiotherapists, occupational therapists, healthcare professionals), exergaming researchers, as well as experts from the exergaming industry (Manser et al., 2023) to specify a set of design requirements for the Brain-IT training concept. In phase 2, possible concepts were co-designed and elaborated based on the set of design requirements defined in phase 1. The first prototype of the resulting Brain-IT training concept (Manser & de Bruin, 2021) then entered the iterative cycle of feasibility, usability, safety, and acceptance testing and integrating study results for further development based on co-design until an "acceptable" solution was achieved. In this regard, we conducted a pilot randomized controlled study (RCT) including 18 individuals with mNCD. (Manser et al., 2023) Finally, in phase 3, the effectiveness of the addition of the Brain-IT training to usual care to improve global cognitive functioning is investigated in a RCT including 41 individuals with mNCD (study protocol: Manser et al., 2023). As secondary objectives, the effects of the Brain-IT training on: (1) domain-specific cognitive functioning, (2) spatiotemporal parameters of gait, (3) instrumental activities of daily living and (4) psychosocial factors (i.e. quality of life, and levels of depression, anxiety, and stress), and (5) cardiac vagal modulation are explored. Additionally, brain structure and function is evaluated by magnetic resonance imaging to explore underlying neural changes of the training in relation to adaptations in cognitive performance.
Results
Ten secondary end users, exergaming researchers, and experts from the exergaming industry (80% females) and eight older adults with mNCD (38% females) contributed to the qualitative research (Manser et al., 2023) which allowed us to successfully integrate all the acquired knowledge of phase 1 to determine a set of design requirements (Manser & de Bruin, 2021). This set of design requirements built the basis for phase 2, where we developed a first prototype of the Brain-IT training concept. Our reflections on the design considerations and our proposed solutions are summarized in (Manser & de Bruin, 2021; Manser et al., 2023). The Brain-IT training concept represents a guideline for applying a combination of exergame-based motor-cognitive training and HRV-BF training by standardizing the training characteristics as well as the structure and content of training and can be implemented with different hardware and software solutions. For an overview, the Brain-IT training consists of a personalized and individually adapted multi-domain exergame-based simultaneous motor–cognitive training with incorporated cognitive tasks combined with HRV-BF training. It is adopted with a deficit-oriented focus on the neurocognitive domains of (1) learning and memory, (2) executive function, (3) complex attention, and (4) visuospatial skills. Each participant is instructed to train ≥ 5x/week for ≥ 24 min per session resulting in a weekly training volume of ≥120 min. All training sessions are planned to take place at participants’ homes. In this project, we used technology of Dividat AG, Polar, and Kubios Oy to implement our training concept. In the pilot RCT we showed that Brain-IT training is feasible (mean adherence and compliance rates of 85.0 and 84.1%, respectively) and usable (mean system usability scale = 71.7 ± 15.4). In addition, high levels of exergame enjoyment, an increase in exergame enjoyment, and internalization of training motivation with large effect sizes (p = 0.03, r = 0.75 and p = 0.03, r = 0.74, respectively), as well as acceptable perceived usefulness were observed. Phase 3 is ongoing. To date, 41 participants were included into the study, of which two withdrew consent before pre-measurements, two dropped-out during intervention (one in each group), and 29 (72.6 ± 9.3 years; 24.1% females) successfully completed the study. Preliminary data suggest significant effects with large effects sizes in favor of the intervention group for global cognitive functioning (F(1, 29) = 4.692, p = 0.039, partial η2 = 0.153) as well as immediate (F(1, 29) = 6.501, p = 0.018, partial η2 = 0.213) and delayed (F(1, 29) = 5.227, p = 0.031, partial η2 = 0.179) verbal recall. The remaining (underpowered) statistical analyses revealed no significant effects, but favorable changes in descriptive statistics with small to moderate effects in favor of the intervention group, especially with regards to quality of life.
Discussion/Conclusion
The development of novel (exergame-based) training concepts is greatly facilitated when it is based on a theoretical framework. Applying the MIDE-framework resulted in a structured, iterative, and evidence-based approach that led to the identification of multiple key requirements for the exergame design as well as the training components that otherwise may have been overlooked or neglected. This resulted in a user-centered, personalized, and highly innovative training concept that is feasible, usable, and highly accepted by individuals with mNCD. Preliminary data regarding the effectiveness of the intervention is promising, suggesting that the training significantly improved global cognitive functioning, verbal immediate, and delayed recall with large effect sizes, and tends to be beneficial in improving quality of life. To be able to conclude about the effectiveness of the Brain-IT training concept, a full-scale confirmatory randomized controlled superiority trial is warranted.

Development of basic motor competencies and connections with sport participation
No full textIntroduction
During childhood, children develop their motor competencies. Basic motor competencies (BMC) are a central prerequisite for participation in sport activities (Herrmann et al., 2016) and form the basis for sport-specific skills (Hulteen et al., 2018). In school, children have a choice of formal (e.g. sports club) and informal (free play) settings in which they can engage in sports activities (Neuber & Golenia, 2018). Children who are active in sports clubs have a higher level of BMC (Herrmann et al., 2017).
Methods
As part of the longitudinal study “Development of basic motor competencies in childhood (EMOKK-study)”, funded by the Swiss National Science Foundation (SNSF), the BMC of N = 659 preschool children (51% boys) and N = 393 1st and 2nd grade children (49.4% boys) were assessed at two measurement points. In addition, parent questionnaires were used to assess the children’s sport participation. In initial analyses, the development of BMC was calculated using ANCOVA, with age as a covariate.
Results
Differences between girls and boys could be observed in preschool as well as in 1st and 2nd grade. Boys showed better performance in “object-movement” whereas girls were better in “self-movement”. From first to second grade, sports club participation increased (F(1, 467) = 28.546, p < .001, η2 = .058). In both measurement points, boys were more often active in sport clubs than girls. First and second graders who were active in a sports club performed significantly better in both competence areas (“object-movement”: t1: p < .001, d = .42; t2: p < .001, d = .68; “self-movement”: t1: p = .002, d = .38; t2: p = .001, d = .40) than children who were not.
Discussion
Children who were active in club sports show a higher level of BMC, which seems to persist in the longitudinal section. This indicates an early selection effect and the importance of BMC for club sport. In further analyses, variables on informal sport activities will also be considered.

Effect of catecholamines stimulation via hand cooling and the priming effect on the oxygen consumption kinetics
No full textIntroduction
Priming effect has been shown to accelerate the oxygen consumption (V̇O2) kinetics. This phenomenon could be explained by muscle oxygen (O2) enhanced delivery, motor unit recruitment or intracellular O2 enhanced utilization (Goulding et al. 2023). Catecholamines such as epinephrine (E) and norepinephrine (NE) are known to impact the cardiovascular system as well as the respiratory system and metabolic effects (Zouhal et al. 2008). The aim of this study is two folds. Observing the effect of increased E and NE induced by cold-water hand immersion on V̇O2 kinetic during heavy intensity exercise bout (HCWR). Compare the effect of cold-water hand immersion and previous HCWR on V̇O2 kinetic to see if the sympathetic system could partially explain the priming effects.
Methods
Ten healthy active males (mean ± SD, age 23 ± 5 years, body mass 71 ± 6.5 kg) participated in this study. An incremental test was performed on ergometer to prescribe the intensity for the HCWR exercise (∆ 25%). Participants did an 8 min HCWR normal bout (NO), followed by 8 min rest and a second bout (SB) and hand cooling bout (HC) at heavy intensity in a randomized order. For the HC condition, participants put hands in cold water (0°C) for 2 min then directly did the HCWR. Blood samples has been taken at rest, before and directly after the HCWR.
Results
Just before exercise, all conditions were different, but HC E (1.095 ± 0.64 nmol/ml) increased by 347% while HC NE (6.98 ± 1.89 nmol/ml) matched values from SB NE (6.89 ± 2.22 nmol/ml). At the end of exercise, no significant difference has been found between NO E (1.44 ± 1.06) and HC E (1.54 ± 1.38 nmol/ml) while SB E (2.35 ± 1.55 nmol/ml) was significantly higher than both conditions but no differences have been found between HC (20.15 ± 8.76 nmol/ml) and SB (20.41 ± 9.74 nmol/ml) NE. V̇O2 kinetic has been sped up for both HC and SB by increasing the absolute primary prime amplitude of HC (33.88 ± 0.96 ml/min/kg),SB (34.60 ± 0.86ml/min/kg) compared to NO (32.75 ± 0.65 ml/min/kg) and reducing the prime amplitude of HC (3.22 ± 0.51 ml/min/kg), SB (2.90 ± 0.64 ml/min/kg) vs NO (3.87 ±0 .56 ml/min/kg) of the slow component of V̇O2.
Discussion/Conclusion
Catecholamines stimulation via hand cooling accelerated the V̇O2 kinetics enhancing the primary phase and reducing the slow component. This effect seemed to follow the priming effect but with less intensity. Increased O2 delivery appeared to be a common feature of both conditions, Motor neuron excitability due to increased NE was also a likely hypothesis, as both HC and SB had the same values just before exercise. Finally, intra-muscular enhancement illustrated by improved intracellular partial pressure kinetics and mitochondrial O2 utilization might explain the effects of catecholamines and part of the priming effect. Mitochondrial “warm-up” could be influenced by both catecholamines and priming effect resulting in a better production of adenosine triphosphate.

Are there specific molecular adaptations of skeletal muscle to repeated sprint training in hypoxia?
No full textIntroduction
Athletes increasingly engage in repeated sprint training that consists of repeated short all-out effort (< 10 s) interspersed by short recoveries (< 60 s). When performed in hypoxia (repeated sprints in hypoxia, RSH), it may lead to greater training effect than in normoxia (RSN). However, the mechanisms underlying this superior training effect of RSH are unclear. Specifically, the role of muscle metabolic response to RSH is still debated and results are heterogeneous. Clarifying the molecular pathways of skeletal muscle adaptations to RSH may thus provide new insights into the role of hypoxia-induced response to training.
Methods
Two groups of healthy young men (randomized) performed three training sessions/week for three weeks. Each training session consisted in six series of six sprints (6 s effort/24 s rest) in either normoxia (RSN, n = 7) or normobaric hypoxia (FiO2 = ~13%, RSH, n = 9). Before and after the training period, vastus lateralis muscle biopsies, a repeated sprint ability (RSA) test and a Wingate test were performed. Metabolic muscle adaptations were studied with proteomics and western blotting.
Results
RSN and RSH similarly improved power output (p < 0.05) during the RSA test (RSN: + 7.2 ± 7.7% vs. RSH: + 7.9 ± 6.6%) and the Wingate test (RSN: + 1.3 ± 3.6% vs. RSH: + 4.4 ± 5.0%). Proteomics revealed a decrease in several processes involved in oxidative phosphorylation, confirmed by Western Blot with a reduction (p < 0.05) in complexes I (- 19 ± 30%) and V (- 15 ± 24%) protein levels in response to both RSN and RSH. RSN and RSH increased (p < 0.05) protein levels of the hypoxia inducible factor 1α (HIF-1α, + 111 ± 50%) and vascular endothelial growth factor A (VEGFa, + 91 ± 60%). Protein levels of the glycolytic enzyme hexokinase II increased (+ 119 ± 183%, p < 0.05) after both training types. Only RSH induced increased glucose transporter 4 (GLUT4, + 31 ± 18%, p < 0.05) protein level, suggesting specific glycolytic adaptations in response to hypoxia, supported by proteomics data. This specific adaptation may be triggered through the signaling of S100A protein family as we observed an increased S100A13 protein level (+ 467 ± 353%, p < 0.05) and Akt phosphorylation (+ 21 ± 21%, time x group interaction, p < 0.05) as well as several other S100A proteins in proteomics only after RSH training.
Discussion/Conclusion
To conclude, RSH did not exhibit in greater performance improvement compared to RSN. However, it further improved the glycolytic phenotype compared to RSN, possibly through specific S100A13 proteins signaling. Thus, we suggest that the reported superiority of RSH to RSN in the literature may stem from superior glycolytic adaptations triggered through the activation of a specific pathway involving S100A13 protein. The potential role of S100A13 protein in skeletal muscle adaptative responses to exercise is novel and the present results open new research perspectives in this field
