Return to On-Snow Performance in Ski Racing After Anterior Cruciate Ligament Reconstruction.

The individual variation in on-snow performance outcomes after anterior cruciate ligament (ACL) reconstruction (ACLR) in elite alpine ski racers has not been reported and may be influenced by specific injury characteristics. To report the performance statistics of elite ski racers before and after ACLR and to identify surgical and athlete-specific factors that may be associated with performance recovery. Descriptive epidemiological study. International Ski and Snowboard Federation (FIS) points, FIS ranking, average placing, and average percentage behind the winning time in each race were calculated for 30 national and provincial team ski racers at 1 year before and 3 years after ACLR. Injury characteristics were obtained from operative reports and clinical notes. The mean age at the time of primary ACLR was 21.6 ± 3.5 years. Overall, 27 of 30 (90%) ski racers returned to the same preinjury competition level. Yet, only 16 of 30 (53%) improved in FIS points, and 13 of 30 (43%) improved in FIS ranking, in one of the speed or technical disciplines by 3 years after surgery. Of the skiers who improved in FIS points, 36% sustained multiligamentous injuries, 45% sustained meniscal tears, and 45% sustained chondral lesions. Of those who failed to improve in FIS points, 50% sustained multiligamentous injuries, 50% sustained meniscal tears, and 60% sustained chondral lesions. Meniscal tears and chondral lesions occurred mostly on the lateral side. The medial collateral ligament was involved in 8 of 9 multiligamentous injuries. These findings suggest significant individual variation in the recovery of on-snow performance of ski racers after ACLR, despite returning to the same competition circuit. The pattern of secondary injuries alongside primary ACL ruptures showed little association with improved performance.

Metabolic Phenotyping from Whole-Blood Responses to a Standardized Exercise Test May Discriminate for Physiological, Performance, and Illness Outcomes: A Pilot Study in Highly-Trained Cross-Country Skiers

BackgroundThis study used metabolic phenotyping to explore the responses of highly-trained cross-country skiers to a standardized exercise test, which was part of the athletes’ routine testing, and determine whether metabolic phenotyping could discriminate specific physiological, performance, and illness characteristics.MethodsTwenty-three highly-trained cross-country skiers (10 women and 13 men) participated in this study. Capillary whole-blood samples were collected before (at rest) and 2.5 min after (post-exercise) a roller-ski treadmill test consisting of 5–6 × 4-min submaximal stages followed by a self-paced time trial (~ 3 min) and analyzed using mass spectrometry. Performance level was defined by International Ski Federation distance and sprint rankings. Illness data were collected prospectively for 33 weeks using the Oslo Sports Trauma Research Center Questionnaire on Health Problems. Orthogonal partial least squares-discriminant analyses (OPLS-DA) followed by enrichment analyses were used to identify metabolic phenotypes of athlete groups with specific physiological, performance, and illness characteristics.ResultsBlood metabolite phenotypes were significantly different after the standardized exercise test compared to rest for metabolites involved in energy, purine, and nucleotide metabolism (all OPLS-DA p < 0.001). Acute changes in the metabolic phenotype from rest to post-exercise could discriminate athletes with: (1) higher vs. lower peak blood lactate concentrations; (2) superior vs. inferior performance levels in sprint skiing, and (3) ≥ 2 vs. ≤ 1 self-reported illness episodes in the 33-week study period (all p < 0.05). The most important metabolites contributing to the distinction of groups according to (1) post-exercise blood lactate concentrations, (2) sprint performance, and (3) illness frequency were: (1) inosine, hypoxanthine, and deoxycholic acid, (2) sorbitol, adenosine monophosphate, and 2-hydroxyleuroylcarnitine, and (3) glucose-6-phosphate, squalene, and deoxycholic acid, respectively.ConclusionMetabolic phenotyping discriminated between athlete groups with higher vs. lower post-exercise blood lactate concentrations, superior vs. inferior sprint skiing performance, and more vs. less self-reported illnesses. While the biological relevance of the identified biomarkers requires validation in future research, metabolic phenotyping shows promise as a tool for routine monitoring of highly-trained endurance athletes.

Managing Organizational and Media Stress: The Case of Elite Norwegian Skiers

This case study focuses on how Norwegian ski jumpers performed in the Beijing 2022 Winter Olympics and the following FIS (International Ski and Snowboard Federation) ski flying World Championships 2022 in Vikersund, Norway, despite organizational conflict at the management level and intense and sustained media coverage the entire season. Five athletes (one third of the elite squad) were interviewed about how they coped with the stressors. The results revealed two main responses: One group avoided, as far as possible, hearing or reading about the conflicts and tried to stay in their “bubble” and focus on preparing for competition. The other group chose to follow the conflicts and was more willing to interact with the media, therefore experienced a higher degree of perceived stress, and consequently needed to employ a wider range of coping strategies. The findings highlight the importance of a consistent and effective management strategy in helping athletes to focus on training and competition preparation and insulate them from stressors generated by organizational turbulence and conflicts.

Opularization of Nordic Combined Through the Introduction of New Disciplines in the Program of Various Ranks Competitions.

Topicality. The presented research paper examines and analyzes the regulations for holding Nordic combined competitions at the Olympic and non-Olympic disciplines. The main changes and expansion of sports competition programs, which took place during the last decades and influenced its popularization, have been described. The purpose of the research. Analysis of the dynamics and reasons for the introduction of new disciplines into the program of competitions of various ranks at Nordic combined. Research methods. Analysis and generalization of scientific and methodological literature, theoretical analysis of regulatory documents and documentation of competitive sports activities (detailed analysis of the International Ski and Snowboard Federation`s bulletins) and review of research analytical sources and information from e-resources (search and analysis of historical data). The research results. Based on a detailed analysis of scientific and methodological sources and available Internet sources as well as the new competition rules, it was found that the basis of the Nordic combined competitions is the following disciplines: a) the individual Gundersen competitions (standard normal and large ski jumping hills; 10 km competition in cross-country skiing), the Men's team sprint competition (included into the program of the Winter Olympic Games only for men); b) the mass start (individual competitions), the Women`s individual Gundersen competitions, the Women`s team sprint. This allowed to systematize the peculiarities of competitive activity and highlight the main aspects in the above mentioned disciplines in accordance with the modern rules of the Nordic combined competitions. Findings. Among the reasons for radical changes and innovations into the Nordic combined was a long stagnation and reluctance to make unpopular decisions, which led to a decline, a decrease in popularity and the number of the competition participants. During the 100-year FIS history, the most changes occurred at the end of the 20th – beginning of the 21st century, in particular, the Gundersen method application, the introduction and search for new disciplines, etc.

Performance and jump-to-jump development in the first female ski flying competition in history.

In 2023, for the first time in history, the international ski and snowboard federation (FIS) arranged an official ski flying competition where the 15 highest ranked women were allowed to participate. This study investigated jump-to-jump performance development in female ski flying, with men's results used as reference data. Official FIS data from all six jumps of women were evaluated together with the eight jumps by men. Performance was evaluated by a score, where the distance points compensated by wind were divided by take-off speed, enabling performance to be evaluated across jumps and sexes. Women improved performance by 96% from the first to the sixth jump, with two major leaps; from the first to the second jump and from the first to the second day. In contrast, men mainly improved from training to competition. The best women had performance scores equivalent to the 10-20 best ranked men and the sex-difference between the top 3 athletes was 26.2%. This difference was thereafter compared to similar results in the normal and large hill World championship in Planica 2023, in which sex-differences between the top 3 were 8.6% and 14.6% in normal and large hill. This historical competition showed the importance of gaining practical experience with ski flying on performance, exemplified by the large improvement of female athletes. This, together with the enlarge sex-differences in large compared to normal hills, indicates that female ski jumpers have a particularly large improvement-potential in ski flying and must gain specific experience on this through traning and competitions.

Judging athletic movement in moving images: a critique of agonic reason in representations of alpine sport, seen through the Paltrow v. Sanderson ski crash trial

ABSTRACT This paper concerns the judgement and critique of athletic movement in moving images. Inspired by the ski crash trial case of Paltrow v. Sanderson, and by comparing different media representations of downhill skiing, the essay outlines a framework that discerns as well as connects elements of movement and images, developing the concept of the ‘diorama’ in relation to Deleuze’s notion of the diagram and Kant’s idea of critique. Thus, moving images featuring elite alpine skier Mikaela Shiffrin, fictional character James Bond, and an official skiing game for the international ski federation (World Cup Ski Racing, FIS) figure as comparative material to the animation that played a central role in the celebrity trial. Diorama and diagram are posited on a continuum to assess when and how judgement takes place in each of the exhibits. The essay concludes by discussing how the judging of athletic movement in moving images contributed to Paltrow winning the case, and theoretically by connecting this finding to dioramas and diagrams as tools apt for a framework aiming at the critique of athletic movement in moving images.

Using Multivariate Data Analysis to Project Performance in Biathletes and Cross-Country Skiers.

To determine whether competitive performance, as defined by International Biathlon Union (IBU) and International Ski Federation (FIS) points in biathlon and cross-country (XC) skiing, respectively, can be projected using a combination of anthropometric and physiological metrics. Shooting accuracy was also included in the biathlon models. Data were analyzed using multivariate methods from 45 (23 female and 22 male) biathletes and 202 (86 female and 116 male) XC skiers who were all members of senior national teams, national development teams, or ski-university or high school invite-only programs (age range: 16-36y). Anthropometric and physiological characteristics were assessed via dual-energy X-ray absorptiometry and incremental roller-ski treadmill tests, respectively. Shooting accuracy was assessed via an outdoor standardized testing protocol. Valid projective models were identified for female biathletes' IBU points (R2 = .80/Q2 = .65) and female XC skiers' FIS distance (R2 = .81/Q2 = .74) and sprint (R2 = .81/Q2 = .70) points. No valid models were identified for the men. The most important variables for the projection of IBU points were shooting accuracy, speeds at blood lactate concentrations of 4 and 2mmol·L-1, peak aerobic power, and lean mass. The most important variables for the projection of FIS distance and sprint points were speeds at blood lactate concentrations of 4 and 2mmol·L-1 and peak aerobic power. This study highlights the relative importance of specific anthropometric, physiological, and shooting-accuracy metrics in female biathletes and XC skiers. The data can help to identify the specific metrics that should be targeted when monitoring athletes' progression and designing training plans.

Carbohydrate intake in young female cross-country skiers is lower than recommended and affects competition performance.

(1) To evaluate if energy availability (EA), macronutrient intake and body composition change over four training periods in young, highly trained, female cross-country skiers, and (2) to clarify if EA, macronutrient intake, body composition, and competition performance are associated with each other in this cohort. During a one-year observational study, 25 female skiers completed 3-day food and training logs during four training periods: preparation, specific preparation, competition, and transition periods. A body composition measurement (bioimpedance analyzer) was performed at the end of the preparation, specific preparation, and competition periods. Competition performance was determined by International Ski Federation (FIS) points gathered from youth national championships. EA (36-40 kcal·kg FFM-1·d-1) and carbohydrate (CHO) intake (4.4-5.1 g·kg-1·d-1) remained similar, and at a suboptimal level, between training periods despite a decrease in exercise energy expenditure (p = 0.002) in the transition period. Higher EA (r = -0.47, p = 0.035) and CHO intake (r = -0.65, p = 0.002) as well as lower FM (r = 0.60, p = 0.006) and F% (r = 0.57, p = 0.011) were associated with lower (better) FIS-points. CHO intake was the best predictor of distance competition performance (R2 = 0.46, p = 0.004). Young female cross-country skiers had similar EA and CHO intake over four training periods. Both EA and CHO intake were at suboptimal levels for performance and recovery. CHO intake and body composition are important factors influencing competition performance in young female cross-country skiers.

The Alpine Ski World Cup: a ‘game changer’ for the International Ski Federation (1967–1975)?

ABSTRACT On 5 January 1967, the small ski resort of Berchtesgaden in Germany made skiing history. The men's slalom on that day was the first race on the newly created World Cup circuit. While media coverage is booming with the democratisation of television, which the newspaper L’Equipe wants to develop its activities, the international ski scene is undergoing a profound revolution that will have consequences on the very structure of the governing body of world skiing, the International Ski Federation (FIS). If the beginnings of the World Cup were briefly explained by Montérémal, it's interesting to analyse the repercussions and the dynamics that are taking place within the FIS before and after this event. Based on a rich corpus of archives from the FIS, the IOC and the sports daily L’Equipe, this research reveals the dynamics that led to the creation of the Alpine Skiing World Cup, questions the way in which the FIS governing bodies managed the arrival of a private player, L’Equipe, on the international ski scene, and notes the consequences of the creation of the Skiing World Cup on the development and finances of the FIS.

The influence of tactical positioning on performance in sprint cross-country skiing.

The purpose of this study was to examine the influence of tactical positioning on performance in the heats of sprint cross-country (XC) skiing among men and women and the consistency of overtaking events over repeated competitions on the same racecourse. Thirty male and thirty female elite to world-class level skiers within each competition [(sprint International Ski and Snowboard Federation (FIS) points: 40 ± 21 vs. 35 ± 24)] performed two repeated world-cup competitions at four different venues (two in the classical and two in the skating style) between 2017 and 2020. The intermediate rankings at five checkpoints were analysed using television broadcasts of the competitions. Sprint time-trial (STT) rank correlated positively with the final rank for the seven men's (ρ = .54-.82, P < .01) and the eight women's (ρ = .40-.80, P < .05) competitions, while one of the classical competitions for males did not correlate significantly (P = .23). The strength of the correlation coefficients between intermediate ranks and final ranks during the heats increased gradually from the first to the last checkpoint among both sexes in the classical style (τ = ~0.26 to ~0.70) and in the skating style (τ = ~0.22 to ~0.82), in which the majority of performance-variance was decided before the start of the finish sprint. For both sexes, ~20 and 16 overtaking events were observed in each heat for the classical and skating style, respectively. There was a significant sex-difference in the number of overtaking events in one out of the 16 competitions (P < .01), but no differences across seasons for any competition (P = .051-796). Overall, this study showed the importance of tactical positioning for performance in sprint XC skiing, with the number of overtaking events being relatively consistent for competitions performed on the same racecourse.

Impact of the revised starting lottery in the alpine speed events on performance of the top athletes

Before the 2016/17 season, the International Ski Federation conducted major changes to its starting lottery, which defines the starting order in advance of each race of the speed disciplines. As part of this change, the top seeded athletes from then on were able to pick a starting position. Therefore, the aim of this study is two-folded. First, we explored the pick behavior of the top athletes and analyzed if they were able to identify favorable starting positions. Second, we investigated the influence of the rule change on competitive balance. Our sample consisted of 322 races with 17,725 individual performances of the seasons 2011/2012 to 2020/2021 and all our analysis were run separately for Women’s Downhill, Women’s Super G, Men’s Downhill and Men’s Super G. We could show that for all disciplines and both genders athletes heavily preferred to start around starting position 7. To start from such positions only led to significantly better rankings in Men’s Super G (z = 2.04, p = .041), but common language effect size showed the same trend for Women’s Super G (CL: 51.9%) as well as Men’s (CL: 53.3%) and Women’s Downhill (CL: 53.6%) competitions. In addition, male starters seeded among the top 7 performed significantly better after the rule change (Downhill: z = 2.95, p = .002; Super G: z = 2.89, p = .002), whereas they performed worse in Women’s Super G (z = -2.77, p = .005). Our findings indicate that there is a change in competitive balance for men’s competitions but not for women’s competitions. In addition, combining these findings with the detected picking preferences of the top athletes, we conclude our work with suggestions for further adaptions of the starting lottery.

The return from underperformance to sustainable world-class level: A case study of a male cross-country skier.

Purpose: To determine the main factors associated with unexpected underperformance and prospectively describe the holistic process of returning to sustainable world-class level in a male cross-country skier. Methods: Longitudinal training data was retrospectively analyzed across nine seasons (2012-2013 to 2020-2021), and categorized into training forms (endurance, strength, and speed), intensities [low- (LIT), moderate- (MIT), and high-intensity training (HIT)], and modes (specific and non-specific). Performance data was obtained from the International Ski and Snowboard Federation. Following two seasons of unexpected underperformance (2019-2020 and 2020-2021), the participant was prospectively followed in the process of returning to sustainable world-class level (2021-2022). Day-to-day training data and physiological tests were analyzed, and interviews with the participant and the head coach conducted. Results: Longitudinal training data from 2012-2013 to 2018-2019 demonstrated a non-linear 30% increase in total training volume (from 772 to 1,002h), mainly caused by increased volume of ski-specific endurance training without changes in intensity distribution. Coincidingly, the participant gradually reached a world-class performance level. After two seasons of unexpected underperformance with relatively similar training volumes and intensity distributions as in the preceding seasons, the possible contributing factors were identified: lack of training periodization, limited monitoring and intensity control, particularly in connection with a "extreme" regime of training with low carbohydrate availability and days including two MIT sessions, as well as lack of systematic technique training and follow-up by coaches on a daily basis. Consequently, the return to world-class level included the introduction of a clear micro-cycle periodization, more systematic physiological monitoring and testing, more accurate intensity control, increased carbohydrate intake during and between sessions, as well as increased emphasize on technique training and an assistant coach present during day-to-day training. Conclusion: These longitudinal data describe the main factors leading to unexpected underperformance, in addition to providing unique insights into the corresponding process of returning to sustainable world-class level in a male cross-country skier. The holistic approach described in this case study may serve as a theoretical framework for future studies and practical work with underperforming endurance athletes.

The influence of race tactics for performance in the heats of an international sprint cross-country skiing competition.

The purpose of this study was to examine the influence of race tactics for performance in the heats of an international sprint cross-country (XC) skiing competition in the classical style. Thirty elite male XC skiers (age: 24±3 years, sprint International Ski Federation [FIS] points: 61±27) performed a sprint time-trial (STT) followed by one to three 'knock-out' heats on a 1.7 km racecourse. An integrated GNSS/IMU system was used to determine position, sub-technique distribution and kinematics. Positioning was analysed using the television broadcast of the race. STT rank correlated positively with the final rank [(rs (28) = .72, P = .001)]. The top-two finishers in each heat were on average ~3.8% slower in the heats compared to the STT (237.1±3.9 vs. 228.3±4.0 seconds, P = .001). On average, the skiers performed ~10 overtakings per 100 meters from the start to the last uphill segment but only ~3 overtakings per 100 meters in the last two segments in each heat. 93.8% of the top-two finishing skiers positioned themselves at top 2 before approaching the final uphill, in which the top-two finishers and the skiers ranked 3-4 were generally faster than those ranked 5-6 in the heats (both, P = .01). Here, top-four skiers employed 5.3% longer cycle lengths and 3.4% higher cycle rates in the diagonal sub-technique than skiers ranked 5-6 (all, P = .01). The present study demonstrates the importance of race tactics for performance in the heats of sprint XC skiing, in which the main performance-determining factors in the present racecourse were a front position when approaching the final uphill segment combined with the ability to ski fast in that segment. In general, this illustrates how accurate racecourse analyses may help skiers to optimize their race-individual race-strategies in the heats of sprint XC skiing competitions.

Estimating skills level in recreational skiing: Development and validation of a practical multidimensional instrument.

Skiing and snowboarding are both popular recreational alpine sports, with substantial injury risk of variable severity. Although skills level has repeatedly been associated with injury risk, a validated measure to accurately estimate the actual skills level without objective assessment is missing. This study aimed to develop a practical validated instrument, to better estimate the actual skills level of recreational skiers, based on the criteria of the Dutch Skiing Federation (DSF), and covering five different skill domains. A sample of Dutch recreational skiers (n= 84) was asked to fill in a questionnaire reflecting seven, a priori chosen predictors by expert opinion, to ski downhill and to be objectively evaluated by expert assessors. The instrument was developed to have a multidimensional character and was validated according to the TRIPOD guideline (Transparent reporting of a multivariable prediction model for individual prognosis or diagnosis). The sample reported an overall incorrect self-reported estimation of their skills, compared with the observed skill score. The instrument showed good calibration and underwent multiple validation methods. The estimated skills score showed to be closer to the observed scores, than self-reportage. Our study provides a practical, multidimensional, and validated instrument to estimate the actual skills level. It proved to better reflect the actual skills levels compared with self-reportage among recreational skiers.

Effect of Polydimethylsiloxane Oil Lubrication on the Friction of Cross-Country UHMWPE Ski Bases on Snow.

Silicone oils are known for their excellent lubricating properties, low toxicity and are ice-, snow-, and hydrophobic. With the upcoming ban on fluorine-containing glide products imposed by the International Ski Federation (FIS), novel glide enhancers for skis are desperately needed. Here, the effect of four silicone oil viscosities (10, 20, 50, and 100 cSt) have been evaluated at three temperatures and snow conditions ranging from −10 °C dry snow to +5 °C wet snow. In dry snow conditions, the shear forces introduced by the silicone oil film increased friction significantly compared to a ski without any treatment. On wet snow, the increased hydrophobicity from the silicone oils reduced the friction by 10%. While commercial glide wax outperformed the silicone oils, this study reports the silicone oils do have desirable friction reducing properties for wet conditions.

The effect of wind on jumping distance in ski jumping depends on jumpers’ aerodynamic characteristics

Several studies have suggested re-evaluation of the wind compensation system (WCS) of the International Ski Federation (FIS). It was introduced in 2009, and since then, the system has been modified considerably, but major shortcomings have still remained. The present study compared the effect of tail/head wind on two reference jumps with different aerodynamic properties (Cd and Cl) during the flight phase. Jump distance and total tangential wind speed data of world cup competitions of the season 2020/2021 were used to analyse the FIS WCS and to offer basic information of wind effects. The correlation between the total tangential wind speed and the jump distance varied strongly among the analysed jumping rounds and showed a big variation in the effect of FIS WCS. According to the computer simulation, a steady head/tail wind during the entire flight phase did not show big difference in jump distance between the jumps with different aerodynamic properties. However, wind had a “reverse” effect on the jumps: when applied to the early flight phase, tail wind increased, and head wind decreased the jumping distance. It seems that the favourable wind conditions at the early flight phase may result in an unfair advantage-disadvantage when the current FIS WCS is used. Therefore, based on the present results, the FIS WCS needs to be further discussed and quality of jumpers’ aerodynamic properties re-examined.

The financial challenges of hosting sports events: a problem of insufficient separation between decision-making and decision-control

ABSTRACT Research question: This article aims to explain that poorly functioning separation between decision-making, decision-control, and risk-bearing is a fundamental reason for the financial underperformance of major or large sport events. We look at empirical data from four major sports events hosted in Norway: The 1994 Lillehammer Winter Olympics, the 2011 International Ski Federation (FIS) World Skiing Championship, the 2014 FIDE Chess Olympiad, and the 2017 International Cycling Union (UCI) World Road Cycling Championships. All these events suffered financially. Research methods: The study data were collected from 66 semi-structured interviews and different types of documents, like guides and reports filed by different stakeholders, applications for financial support, collaboration agreements, protocols of meetings, e-mail correspondence, financial statements, and budgeting documents. Results and findings: Through an examination of the previous literature, our analysis confirms drivers and symptoms of financial problems at sport events. These are: the exaggerated focus on legitimising the event, soft-budget practices, interference by political interests, and so on. We argue that many of these factors could have been handled better if a more consequent separation of risk-bearing, decision-making, and decision-control was in place. Implications: We propose a better separation between the decision-making and decision-control function, by means of a permanent and independent entity that is responsible for the decision-control function. Such an institution could enhance knowledge transfer, contribute competence and skills, and improve the financial outcome of a sports events.

Comparison of Race Time-Differences Between and Within Para and Able-Bodied Cross-Country Skiers.

PurposeTo compare differences in race time (i.e., the average percent difference in race time for each skier compared to the winner, RTdiffs) between female and male Para and able-bodied (AB) skiers, and to examine whether RTdiffs change across seasons.MethodsRace data from World Cups (WCs), World Championships (WCHs), and Paralympic/Olympic Winter Games (PWG/OWGs) of the 2011–2020 seasons was extracted from the website of the International Paralympic Committee and the International Ski Federation. All individual distance races for female and male visually impaired standing (VI), physically impaired sitting (SIT) and standing (STAND), and AB skiers with ≥10 competitors were included in the analyses. We investigated the main effect of skiing groups (i.e., VI, STAND, SIT, and AB skiers) and sex on RTdiffs for top-3 and top-8 skiers. Furthermore, the main effect of season and skiing group on RTdiffs for top-3 and top-8 skiers were investigated. All models were adjusted for distance, skiing style (classical- and freestyle), and event type (WC, WCH, and PWG/OWG).ResultsRTdiffs were significantly larger in Para compared to AB skiers (top-3: 2.1 vs. 0.9%; top-8: 6.2 vs. 2.1%, all p < 0.01), and in female compared to male skiers (top-3: 1.8 vs. 1.3%; top-8: 4.9 vs. 3.5%, all p < 0.05). For top-3 skiers, RTdiffs did not significantly differ between the Para categories (all p > 0.2), while for top-8 skiers RTdiffs were significantly larger for VI compared to SIT and STAND (7.0 vs. 5.5 and 5.6%, respectively, all p < 0.05). RTdiffs were stable across the 2011–2020 seasons for top-3 skiers (VI: 1.7–3.6%, STAND: 1.1–2.2%, SIT: 1.0–3.9%, AB: 0.4–1.1%; all p > 0.1) and top-8 skiers (VI: 3.4–12.0%, STAND: 2.6–5.7%, SIT: 1.9–5.9%, AB: 0.1–1.7%; all p > 0.1).ConclusionThe larger RTdiffs in Para compared to AB skiers indicate larger variability in performance, which are in part disability related. Female skiers displayed larger RTdiffs than their male counterparts, indicating larger variability in performance among the female skiers. Our results provide insights about performance demands in Para cross-country skiing, which is of relevance for coaches and skiers.
