When recovery is too sparse under these circumstances, psychological and physical health problems could emerge. These are referred to as nonfunctional overreaching or overtraining syndrome, OTS (Daly et al., 2022; Jones et al., 2017; Kiely, 2018). OTS is typically characterized by a reduction in athletic performance that lasts for several weeks to months, accompanied with mood and sleep disturbances, feelings of depression, respiratory tract infections, weight loss, and other symptoms. The prevalence of this condition is high with approxymately 10-20 % of young adult and about 29 % of young athletes from various sports beeing affected (Matos et al., 2011). To our knowledge, no scientifically valid and reliable measurement system currently exists, which would allow the preventive, early diagnosis of overreaching states that might lead to OTS (Weakley et al., 2022). The aim of this study is to develop and evaluate a multiparameter measurement system to assess the recovery and stress state of high-level athletes. \u0000Methods \u0000Twenty-five male ice hockey players from the highest level Swiss leagues at their respective age group participated (i.e., National League, NL, n = 11, age = 24.8 ± 4.1 years and U20, n = 14, age = 18.5 ± 1.5 years). Over 5-10 weeks during the in-season (i.e., competition phase) measurements were performed on 10 separate days, either after 1 day of passive recovery (T1) or after a day with match/intensive training (T2). The measurement battery included counter movement jump (CMJ), heart rate variability (HRV), executive functions (EF), tympanic temperature (Temp), and Stress Recovery Short Scale (SRSS). \u0000Results \u0000Independent Student’s t-tests showed significant differences (p < 0.05) between timepoints T1 and T2 for CMJ (peak power per body mass), HRV (sympathic and parasympatic indexes), and SRSS (recovery, stress, total score); but not for CMJ (jump height), EF and Temp. \u0000Discussion/Conclusion \u0000We conclude that various measurment parameters, including CMJ performance, HRV indices, and subjective ratings of recovery and stress could provide valuable feedback for athletes, coaches, and medical staff regarding a potential overreaching or OTS state. \u0000References \u0000Daly, E., Pearce, A.

Eriks-Hoogland, Claudio Perret","doi":"10.36950/2024.2ciss037","DOIUrl":"https://doi.org/10.36950/2024.2ciss037","url":null,"abstract":"Introduction \u0000The primary objective of this study is to explore associations between meeting spinal cord injury (SCI)-specific exercise guidelines and the prevalence of shoulder pain in manual wheelchair users (MWU) with SCI in Switzerland. The rationale behind this investigation lies in the high prevalence of shoulder pain among MWU with SCI, impacting their daily activities, leisure- and labor participation, and overall quality of life. Understanding the association between exercise adherence and shoulder pain is crucial, not only for the well-being of the individuals but also for managing healthcare costs associated with pain treatments. \u0000Methods \u0000The study utilizes data from the SwiSCI Community Survey 2022 (Gross-Hemmi et al., 2021), focusing on a cohort of 593 manual wheelchair users (MWU) for a cross-sectional analysis, investigating the reporting of shoulder pain, and adherence to SCI-specific exercise guidelines (Martin Ginis et al., 2018). The guidelines, proposed by Martin-Ginis et al. (2018), encompass aerobic exercise and muscle-specific strength training. Logistic regression analyses were employed to assess the association of meeting these guidelines and the prevalence of shoulder pain, while considering potential confounding factors. \u0000Results \u0000High prevalence of shoulder pain was observed, affecting 40% of the MWU surveyed, which is in line with previous observations. Additionally, the study found that a significant proportion of the population did not meet the recommended guidelines for aerobic exercise (46%) and muscle strength training (64%). Logistic regression analyses showed that non-adherence to aerobic exercise guidelines was associated with 1.55 to 1.97 higher odds of reporting shoulder pain. No association of muscle strength training with the shoulder pain could be found. Therefore, meeting both aerobic and muscle strength guidelines did not yield any association with shoulder pain. Adjustments for potential confounders such as sex, age, lesion level, completeness, time since injury, and mobility scores, did not change the association between adherence to guidelines and shoulder pain. \u0000Discussion/Conclusion \u0000The prevalence of shoulder pain in the study sample is high (40%) and in line with previous publications. Compared to 75% of the Swiss general population being physical active for more than 2.5 hour a week (Bundesamt für Statistik, 2019), only 54% of the study sample is meeting the guidelines for at least the “Starter level” on aerobic exercise (cardiorespiratory, ≥ 2x 20 min/week). Those who are not meeting the aerobic exercise guidelines have 1.55 to 1.97 higher odds to have shoulder pain. Despite foreseen shoulder fitness benefit, 64% is not meeting the guidelines on muscle strength training. To further examine the relation between shoulder use, -exercise and shoulder pain, longitudinal studies on dose-effect are needed. \u0000References \u0000Gross-Hemmi, M.

A concerning observation is that young cancer patients often lead sedentary or even lying lifestyles, clearly failing to meet the WHO’s recommendation of 60 minutes of moderate-to-vigorous physical activity (PA) daily. This is alarming considering that PA is essential for physical and mental health, e.g., for the development of motor skills and cognitive functions (Bull et al., 2020). However, PA promotion in acute care in Swiss pediatric oncology units is hardly existent. Therefore, the aim of this project is to develop and conduct a physical activity program in a pediatric oncology unit and investigate its effects on cognitive and motor performance.\u0000Methods\u0000Part A of this project involved a qualitative study conducted at the Inselspital Bern’s pediatric oncology unit, aiming to design a tailored PA therapy program. This part included patient interviews and staff surveys. Part B, which is ongoing, focuses on a forthcoming two-arm multicenter crossover-controlled trial. This trial will compare the exercise therapy and PA counseling (intervention group in Bern, n = 40) with standard treatment (control group in Basel, n = 40). Participants will be aged 6-18 years, newly diagnosed with cancer and undergoing cytotoxictreatment for at least six weeks. The 12-week program will consist of thrice-weekly, 45-minute sessions of individualized exercise, aligned with the SK2-guidelines, NAOK, and international Pediatric Oncology Exercise Guidelines (Götte et al., 2022; Wurz et al., 2021). The sessions will focus on motor skills and cognitively challenging PA. In addition, children will receive 4 exercise counseling sessions. To evaluate the study, there will be three measurement points (once at admission, after twelve weeks of intervention and one follow-up after six months). The outcome measures include motor and cognitive performance, physiological and psychosocial functioning.\u0000Results\u0000Initial findings from the qualitative study indicate a strong patient and staff interest in exercise therapy. The study also provided valuable insights for developing and implementing the intervention.\u0000Discussion/conclusion\u0000The results will reveal important insights relevant to research and practice. Adopting a research perspective, the results will shed light on the effects of PA on cognitive performance in acute cancer care. Adopting a more applied perspective, PA has been neglected in Swiss pediatric oncology units so far. Therefore, this study may contribute to proof the effectiveness of PA for childhood cancer patients and thus help implementing it in standard care in the long term.\u0000References\u0000Bull, F.

{"title":"Who’s better? Adaptive comparative judgment of dance performances","authors":"Eric Jeisy","doi":"10.36950/2024.2ciss051","DOIUrl":"https://doi.org/10.36950/2024.2ciss051","url":null,"abstract":"Introduction \u0000Adaptive Comparative Judgment (ACJ) is a promising digital assessment method that allows measurement of performance or competencies by repeated comparisons of two items. Whereas ACJ is becoming a popular assessment method in educational measurement there are no such studies or published use cases in the context of sport or physical education-related teacher education (Bartholomew & Jones, 2022). To address this research gap, an explorative and comparative study was conducted to investigate whether ACJ offers an advantage over the traditional form of criteria-oriented scoring (TA) in the evaluation of students' dance performances. \u0000Methods \u0000In four face-to-face examinations the dance performances of 61 student teachers (82% female) were assessed by two lecturers in each case (n = 5; Age M = 50, 3 women, 2 men). Each lecturer scored independently on an 18-point scale on five different evaluation categories (e.g., technical quality). In addition, the dance performances were videotaped, and the same five lecturers assessed the dance performances again using the ACJ tool Comproved. To analyze interrater agreement and reliability, intraclass correlation (ICC) was calculated for the traditional assessment (Sato, 2022). The reliability of the ACJ was analyzed by calculating scale separation reliability (SSR; Verhavert et al., 2019). A Spearman’s rank correlation analysis was conducted to analyze whether there is a correlation between the ranked results of the two assessment methods. To assess the validity of the assessment methods, a focus group interview was conducted with the lecturers involved in the study. \u0000Results and Discussion \u0000Both assessment methods are characterized by very high and high reliability values (TA: ICC = 0.974, 95% confidence interval (CI): 0.955-0.985 p < .001; ACJ: SSR: 0.83, Ability [-5.97, 4.99], Misfit [-1.68, 1.34]). In particular, the ICC of the TA is higher than comparable results in dance research (Sato, 2022). There are doubts as to whether the lecturers really scored independently of each other at the face-to-face examinations. The ranked results of both methods correlate with a very strong effect (Spearman’s-Rho: rs -.818, p < 0.001). However, detailed analyses show some differences. The answer to the question of who delivered the best dance performance differs depending on the assessment method. In addition, in the traditional assessment, many scores fall on a value at which the dance examination is just passed (10 points). The results of the focus group interview are still being analyzed and will be presented at the conference. \u0000References \u0000Bartholomew, S. R., & Jones, M. D. (2022).

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. \u0000Methods \u0000Two 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. \u0000Results \u0000RSN 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. \u0000Discussion/Conclusion \u0000To 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.","PeriodicalId":415194,"journal":{"name":"Current Issues in Sport Science (CISS)","volume":"112 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139799840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eccentric training shows greater gains in muscle strength and mass with lower cardiovascular and metabolic demands (Douglas et al., 2017; Roig et al., 2009). This, combined with the time-efficient components, makes eccentric training particularly attractive for use in athletes with spinal cord injury (SCI). Despite an increasing number of studies focusing on eccentric training in the lower extremities, little is known about the effects in upper body extremities. Therefore, the main objective of this study was to investigate the feasibility of an eccentric arm-crank training protocol and its effects on upper body performance in elite athletes with SCI.\u0000Methods\u0000Nine strength training experienced elite athletes (median (Q1-Q3) age 29 (25–35) years) 6 men, 6 (3-10) years active as elite athlete, 12 (10-13) hours of weekly training) with SCI were recruited. The athletes were active in various wheelchair sports including basketball, cycling and athletics. The athletes performed twenty eccentric arm-crank training sessions (2-3 sessions/week for 10-12 weeks), during which intensity (74-182% of predetermined maximal aerobic power) and duration (8-14 min) were progressively increased. The following parameters were assessed before and after the intervention: maximal strength (one repetition maximum (1RM) bench press, grip strength), anaerobic performance (Wingate test), aerobic performance (V̇O2peak-ramp test), arm circumferences. The normal training routine was continued during the study.\u0000Results\u0000Nine athletes with paraplegia successfully completed the eccentric arm-cranking protocol. The cardiometabolic demands of the training sessions were relatively low at an intensity of 69% (66-76) of maximum heart rate. The athletes improved their maximal aerobic power (+3%, p = 0.047) and increased their arm circumferences (+1-3%, p ≤ 0.027). The further parameters showed no significant improvements, nevertheless most athletes showed individual improvements in all parameters.\u0000Discussion/Conclusion\u0000Twenty sessions of progressive eccentric arm-cranking, added on top of the normal training routine, improved performance in elite athletes with SCI. The individual improvements found in the athletes are clinically relevant as in this well-trained population, any further gains in upper body performance can be difficult to reach. Nevertheless, such progress can make a critical difference in competition. These preliminary data suggest that our protocol is a feasible method for improving upper body performance in elite athletes using eccentric strength training.

Numerous sports organizations and sports policymakers are committed to enable more inclusive sport. Led by the idea of a sport for all, everyone should be able to participate in sport regardless of gender, sexuality, dis_ability, race, or class.\u0000Inclusive sport does not only require specific structural conditions. It also demands social actors who have the skills to deal with the challenges of social diversity in an open, appreciative, and innovative way. Coaches, officials, teachers, journalists, and economists working in the field of sport need to be familiar with the topics of gender equity, diversity, and inclusion. This is where the project “Understanding and Experiencing Diversity” (funded by the Swiss Federal Office for Sport) comes in. It aims to develop and test a concept for promoting gender and diversity competence in sport-related higher education, thus enabling social actors to shape sport in a diversity-conscious and inclusive way.\u0000Methods\u0000The project is being carried out over a period of three years and consists of four project phases. After a phase of conceptual clarification regarding the theoretical framework and terminology, current approaches to gender and diversity competence (in the sport studies context) are being critically analysed. Against this background, phases three and four of the project will focus on the development of a sport-related teaching concept for gender and diversity competence and its testing at three different universities.\u0000Results/Discussion\u0000The understanding of gender and diversity competence developed in this project is theoretically based on the “trilemma of Inclusion” by Boger (2019). It thus refers to inclusion and non-discrimination as a complex structure of normalization, deconstruction, and empowerment. This is also linked to an intersectional perspective on social differentiation and discrimination (Degele & Winker, 2011).\u0000Regarding the promotion of gender and diversity competence in higher education, the attitude of social actors towards diversity and inclusion proves to be particularly important. This aspect has not yet been systematically considered in the context of sport-related higher education in German-speaking countries. The teaching concept developed in this project therefore emphasizes the aspect of attitude (Rischke et al., 2017).\u0000References\u0000Boger, M. A. (2019).

Women are more likely affected by AMS than men (Richalet et al., 2012). AMS can affect exercise performance. However, the effects of the menstrual cycle (MC) on physiological responses to exercise and on tolerance to high-altitude (HA) remain underexplored. It has been reported that ovarian hormones stimulate ventilation in normoxic conditions (Saaresranta & Polo, 2002). Early findings suggest that running economy is lower in the mid-luteal (ML) compared to the early-follicular (EF) phase in normoxia (Goldsmith & Glaister, 2020). However, cycling efficiency at HA has not been explored yet. Thus, we investigated the effects of acute HA exposure on ventilatory responses at rest and during exercise in healthy females during two different phases of their MC. \u0000Methods \u0000Sixteen eumenorrheic women (age: 33 ± 7 yr; MC length: 27 ± 2 days; not taking any hormonal contraceptive) took part in this study. First, over a 6-month period, the participants’ MC were monitored using a calendar method. Then, they reached the Torino Hut (3,375 m) by cable car and spent one night at HA on two different MC phases; i.e., during the early-follicular (EF; MC day 4 ± 1) and the mid-luteal (ML; day 20 ± 2) phases. Each time, they underwent a submaximal (1.2 W/kg) test on a cycle ergometer ~17 h after arrival at HA. In addition to this, participants filled in two questionnaires, the Lake Louise AMS Score and the Groningen Sleep Quality Scale, ~16 h after arrival at HA. \u0000Results \u0000Resting ventilation was significantly higher during EF compared to ML (15.2 ± 1.9 vs. 13.2 ± 2.5 L/min, p = 0.039), while no differences were found for ventilation during exercise (53.9 ± 13.2 vs. 53.5 ± 13.4 L/min, p = 0.695), cycling efficiency (21.7 ± 0.0% vs. 19.8 ± 0.0%, p = 0.244), saturation at rest (92.4 ± 1.3 vs. 91.3 ± 3.2%, p = 0.142) and during exercise (87.2 ± 5.7 vs. 89.0 ± 4.0%, p = 0.528). Moreover, no differences in the Lake Louise AMS (2.2 ± 1.5 vs. 1.7 ± 1.5, p = 0.266) or Groningen (8.0 ± 3.3 vs. 7.5 ± 3.4, p = 0.668) scores were noted between the two MC phases. \u0000Discussion/Conclusion \u0000Despite a slightly higher resting ventilation during EF, when both oestrogens and progesterone are at their lowest levels, there were no differences in ventilatory responses to exercise and in AMS between the different phases of the MC. Consequently, there is currently very little evidence to aptly recommend a specific MC phase for mountaineering or any other HA activities (Burtscher et al., 2023). Further investigations are requested to assess whether other physiological responses to HA may be influenced by hormonal variations. \u0000References \u0000Bärtsch, P., & Swenson, E. R. (2013).

In their search, the editors of the Swiss girls’ magazine ‘KALEIO – For Girls (and the Rest of the World)’ learnt that the topic is ‘out’. But although we see more and more equalization of sport-related behavior (e.g., Hartmann-Tews, 2009), promoting girls in sport still makes sense.\u0000Methods\u0000The results stem firstly from an overview article, in which international findings were summarized. Secondly, data come from reanalyzes of two representative MOBAK studies, where children were measured by gender-neutral MOBAK-tests and parents were questioned about their children’s physical activity behaviors.\u0000Results\u0000The overview article (Adler & Gramespacher, 2021) compiled international findings on the activity behavior of girls and boys during the transition from kindergarten to grade one. The studies available report on gender-stereotypical behavior of children – and girls stand out here in different ways. Further evidence of gender-stereotypical behavior can be shown by reanalysis of MOBAK-data with 1st graders (Gramespacher et al., 2022) and 3rd graders (Gramespacher et al., in press): Overall, reanalyzed MOBAK-data show, that there is a difference in basic motor competencies that might be explained by gender-stereotype sport socialization – and this clearly is a disadvantage for the girls in some motor competencies.\u0000Discussion/Conclusion\u0000Presented data point out the still existing need for action in promoting girls in sport. We must discuss the complexity associated with the promotion of girls in all fields of sport and in this realm, we must define specific goals of promoting girls in sport (e.g., Kugelmann, 2002). But in future, we should consider the role of differentiation in research and sports practice: Shouldn’t we differentiate in general for all different types of learners without classifying?\u0000References\u0000Adler, K., & Gramespacher, E.

However, the understanding of the role of sport in the resettlement of refugees is limited by a narrow focus on policy-led integration outcomes and player participation (Nunn et al., 2021). Moreover, refugee men prevail as the dominant participants, in not only sporting programs, but also within the research that informs the sport resettlement agenda (Ekholm et al., 2019). Therefore, the participation of refugee women in sport policy and programming is largely understood through refugee men's experiences, where the role of sport in resettlement and the daily lives of refugee women is less well understood. This research, guided by postcolonial feminism, examined how sport is deployed as a resettlement and integration policy tool for refugee backgrounded women living in Melbourne, Australia, and aimed to determine the relevance of sport in the lives of refugee backgrounded women. \u0000Methods \u0000Bacchi (2009) framework for policy analysis examined three government sport policies texts that represented refugee integration as a ‘problem’ to be managed through sport. Interviews with policy actors and sport program providers investigated practices and discourses underpinning refugee women’s inclusion in sport programming. Ethnographic fieldwork conducted over a 12-month period with a culturally diverse community football club, explored the role of sport in the lives of refugee backgrounded mothers and their children. Data was analysed using critical discourse analysis and thematic analysis. \u0000Results \u0000Factors at policy level, i.e. the tokenistic presence of women and girls in policy texts, and programming level, i.e. their inclusion into male dominated spaces shaped by neoliberal agendas, continue to resist refugee women’s participation in mainstream sport. Refugee women’s secondary presence in policy and programming was reinforced by temporary, sporadic and competitive funding opportunities that were heavily reliant on participation numbers and hegemonic masculinity, preserving the privilege of the status-quo. Integration in the policy texts was understood as belonging to the dominant Anglo-Australian culture, but belonging was contested, and the refugee mothers in this study understood belonging as being to their own cultures. Their sporting club was a space of belonging, stress relief, social connection, agency and cultural maintenance. The sport club was an important part of their lives as individuals, and was an important aspect of parenting and motherhood. \u0000Discussion/Conclusion \u0000Our study indicates that policy level and policy actors that promote the inclusion and integration of refugees through sport regularly marginalise refugee women and place them as tokenistic participants.
