Observational vs coaching feedback on non-dominant whole-body motor skill performance - application to technique training.

We studied the effect of peer- and self-observational feedback versus coaching feedback during technique training on performance in competitive adolescent cross-country skiers. Fifty-four skiers (14.3 ± 0.6 years) were divided into a control group and three intervention groups (dyad practice, video, or coaching feedback), which practiced in the asymmetrical uphill sub-technique G2 on one side (non-dominant side), but not the other (dominant side) for 6 × 30 min over a 5 weeks period, on roller skis outdoors. High-speed performance and skiing economy were assessed on a roller ski treadmill before and after the intervention, and a questionnaire was answered post-intervention. The video feedback (p = .025, d = .65) and coaching feedback (p = .007, d = .89) groups improved high-speed performance during the intervention and an ANCOVA showed a tendency for different change scores between interventions (F3,49  = 2.5, p = .068, η p 2  = .134), with a difference between the coaching feedback and dyad practice (p = .05). No change was seen in skiing economy in any group. Coaching feedback ranked higher on enjoyment compared with dyad practice (p < .001) and led to higher self-perception of improved technique compared with the control group (p = .038). Overall, feedback from a competent coach seems better than observation for improving performance in young athletes, although self-observation through video with attentional cues seems a promising tool for increasing individual feedback when coaching large groups.

Do low-priced ski pass owners perceive a higher quality of life? A case study of the Leisure Card Tirol.

OBJECTIVES: The study investigated a potential correlation between owning a superregional low-cost ski and leisure card, namely the Leisure Card Tirol (LCT), and perceived quality of life (QOL). DESIGN: A cross-sectional, quantitative approach (online questionnaire) was chosen. METHODS: In total, 1588 LCT users as well as 684 non-users (residents living in the Alpine region of Tyrol, Austria) were reached throughout the study period. RESULTS: Compared to non-users, LCT users reported significantly higher scores in all domains of QOL. However, the correlation was neither mediated nor moderated by the level of general physical activity (in contrast to alpine skiing in particular). CONCLUSIONS: As superregional low-cost leisure cards were suggested as a way of facilitating access to skiing-at least according to its buyers-owning the LCT was associated with higher perceived QOL. Subsequent research should elaborate the extent to which this correlation is causal. If there is a causal link, such cards should be actively promoted to improve/maintain residents' QOL.

Nationality and sociocultural factors influence athlete development and sport outcomes: Perspectives from United States and Austrian youth alpine ski racing.

Geographical regions possess distinct sporting cultures that can influence athletic development from a young age. The United States (US) and Austria both produce elite alpine ski racers, yet have distinct sport structures (i.e., funding, skiing prominence). In this exploratory study, we investigated sport outcomes and psychological profiles in adolescent alpine ski racers attending skill development academies in the US (N= 169) and Austria (N= 209). Sport participation and psychological questionnaires (mental toughness, perfectionism, grit, coping, burnout) were administered to athletes. In Austria, athletes participated in fewer extracurricular sports, began competing and training younger, and accumulated less practice hours than athletes in the US. Athletes in the US reported greater burnout than athletes in Austria. Finally, in the US, women accumulated more practice hours and experienced more parental pressure than men, while men accumulated more practice hours in Austria. Austria's skiing-centric sport culture may encourage athletes to fully immerse into the sport, contributing to positive psychological outcomes. Reduced sport opportunities in the US beyond educational institutions may pressure athletes to practice more to ensure continued competitive skiing. Stressors for sport participation will be unique to gender in each country though, given their implicit gender stigmas for sport participation.

Constructing a Talent Identification Index System and Evaluation Model for Cross-Country Skiers.

A talent identification index system for male and female cross-country skiers in four age groups (11-12 years old, 13-14 years old, 15-16 years old, and 17-18 years old) was established. The system comprises five body shape indexes ( i =5): Leg-to-Body Ratio (LBR), body fat percentage, maturity status, spreaded brachia index, and upper extremity length. The physiological function indexes ( i =2) are VO2max and haemoglobin mass (Hb). The psychological indexes ( i =5) cover reaction time, perception speed, a quality-of-will scale, an attention test, and operational thinking. The physical fitness indexes ( i =11) comprise upper limb explosiveness, vertical jump, 3000-metre run, orthostatic forward flexion, closed-eyes single-leg stand, standing long jump, 20-metre sprint, pull-ups (males), flexed arm hang (females), hexagon jump, and a Functional Movement Screen (FMS) test. The athletic performance indexes ( i =3) comprise on-snow time trials for 1.2 km, 5 km, and 10 km. The talent identification evaluation model was created using automated evaluation software. The talent identification index system and evaluation standard table for cross-country skiers passed the P60 shortlist and P90 elite boundaries established using the percentile method. Thus, the results of this test profile verify that the evaluative model is objectively effective.

Mindfulness and shooting performance in biathlon. A prospective study.

The aim of the study was to examine the temporal relationship between facets of sport-specific dispositional mindfulness (i e., Awareness, Refocusing, Nonjudgemental attitude) and shooting performance in actual competitions, in a population of 25 elite biathlon athletes. Findings indicated that mindfulness facets were positively associated with shooting performance, with higher levels of Awareness, Refocusing, and Awareness being related to better shooting performance in competitions. In spite of the fact that the explained variance was quite small, even a minor shooting performance enhancement may increase an athlete's chance of winning a biathlon competition.

More than just another bib: group dynamics in an elite Nordic ski team.

The social environment within individual sport teams can have a significant influence on the success, development, and well-being of athletes. We explored elite individual sport athletes' group experiences through the lens of social identity theorising. Participants were six members (4 male, 2 female, Mage = 21.5 years) of a National Development Nordic Ski team. At two time points in the competitive season, we used Social Identity Mapping (Bentley et al., 2020) in combination with semi-structured interviews to explore athletes' experiences as a member of the ski team. Social Identity Mapping provided a visual representation of each participant's social identities and was used to facilitate athletes' views of their group experiences in the semi-structured interviews. Interview data were thematically analysed to explicate participants' perceptions of social identity and cohesion, and their perceived relevance to success and development in elite individual sport. Major themes included social group memberships and identities, the presence of subgroups, the ebb and flow of cohesion and conflict, and teammate and coach influence on the group. On this basis, we argue that social identity mapping can be a valuable resource for athletes and coaches seeking to create a positive and cohesive team environment within an elite individual sport team.

Differences in pacing pattern and sub-technique selection between young and adult competitive cross-country skiers.

The present study describes differences in pacing patterns and sub-technique selection in young compared to adult competitive cross-country skiers. Eleven young male skiers (YOS) (14.4 ± 0.5 years, V ˙ O2peak 63.9 ± 2.8 mL∙kg-1 ∙min-1 ) and eight adult male skiers (ADS) (22.6 ± 4.3 years, V ˙ O2peak 77.4 ± 4.4 mL∙kg-1 ∙min-1 ) performed a free technique rollerski time trial (TT) over a distance of 4.3 km (YOS) and 13.1 km (ADS) to simulate normal racing distances. A GNSS/IMU system was used to track position, speed, and classify sub-techniques. Skiing economy and V ˙ O2peak were measured on an additional day to calculate the relative oxygen demand ( V ˙ O2dem ) in 13 segments of the TT. YOS were slower than ADS in all types of terrain (mean speed difference of 13%), with differences for uphills of 19%, undulating terrain of 11% and downhills of 8% (all P < .05). The mean relative V ˙ O2dem tended to be higher for YOS compared to ADS (120% vs 112% of V ˙ O2peak , P = .09), and the difference was more pronounced in the initial four segments of the race (130% vs 110% of V ˙ O2peak , P < .01). YOS used more of the sub-technique Gear 2 (23 ± 7 vs 14 ± 4%), less Gear 3 (36 ± 7 vs 45 ± 5%), and had more frequent transitions between sub-techniques (18 ± 2 vs 15 ± 3 km-1 ) (all P < .05) than ADS. Over an age-related distance, young skiers tend to exhibit higher mean exercise intensity than adult elite skiers, with a more pronounced positive pacing pattern. Differences in physical ability affect speed and sub-technique selections, implying a need for differentiating technical training for different ages and levels.

Does Age Matter? A Qualitative Comparison of Motives and Aspects of Risk in Adolescent and Adult Freeriders.

Recent research has shown multiple motives for high-risk sport participation derived from research on adult participants. The aim of this study was to provide insights into motives and risk-related aspects in adolescent high-risk sport participants and to compare those findings with adults performing the same activity. Semi-structured interviews were conducted with 24 adolescent (14-20 years) freeriders (skiers/snowboarders who ski outside the protected areas of a ski resort) and 24 adult freeriders (26-41 years). A content analyses was done using MAXQDA software. Both cohorts reported the motives Challenge (adolescents: 92%, adults: 88%), Freedom/Pleasure (adolescents: 88%, adults: 75%), Friends (adolescents: 88%, adults: 79%) and Balance (adolescents: 63%, adults: 63%). However, the description of friends differed between adults and adolescents. Whereas adolescents mostly referred to a community and shared interests, adults described the importance of trust and the development of deep friendships through the activity more often. Nature was a major motive in adults (83%) but not in adolescents (29%). Most of the adults have already experienced a major accident or close call (n = 19; 79%), contrary to adolescents (n = 7; 29%). Adolescents learned about the risks in freeriding primarily through their families (n = 10) and the ski club (n = 9). Some adults reported to have realized the risks involved in freeriding after starting with the activity due to experienced negative outcomes. Both cohorts were largely motivated by the same motives. As the new generation of freeriders seems to receive more instructions about risk reduction, it might be interesting to see if this educational approach results into less accidents or close calls in this group.

Quality of life, concern of falling and satisfaction of the sit-ski aid in sit-skiers with spinal cord injury: observational study.

STUDY DESIGN: Observational study. OBJECTIVE: To describe (1) user satisfaction, (2) the Quality of Life (QoL) and (3) fear of falling in individuals with tetraplegia or paraplegia who used a mono-ski for sit-skiing. SETTING: Spinal units and Sport associations. METHODS: An observational study of people with spinal cord injury (SCI) who used a sit-ski. Participants were recruited in various SCI rehabilitation centers and sport associations. Participants completed three assessment tools: the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST 2.0); the World Health Organization Quality of Life (WHOQoL-BREF); the Spinal Cord Injury Fall Concern Scale (SCI-FCS). Results were evaluated with chi-squared test and Kolmogorov-Smirnov's test and the significance was set for p values < 0.05. RESULTS: Fifteen participants were included. Results showed positive and statistically significant values for all the items of the SCI-FCS related to fear of falling, and for most of the items of the WHOQoL-BREF related to QoL and the QUEST 2.0 related to satisfaction with the device. CONCLUSIONS: This study highlights that sit skiing is correlated with high levels of satisfaction with the mono-ski, increases in QoL, and low levels of fear of falling. In adding these findings to the existent literature, it can be stated with more certainty that sit-skiing is a sport that can be recommended in rehabilitation and sports therapy programs.

Snowboarders' Knowledge of the FIS Rules for Conduct on Ski Slopes.

The objective of the present study is to assess snowboarders' general perceptions of safety and knowledge of existing rules and both active and passive knowledge of the International Ski Federation (FIS) regulations in order to contribute to defining target groups for specific educational interventions in the field of injury prevention. Data were drawn from random interviews conducted with 918 snowboarders during the 2017-2018 winter season at five ski resorts located in the Spanish Pyrenees. To collect the data, a questionnaire assessing personal characteristics (gender, age, origin, and self-reported skill), general perception of safety, general request for rules, and knowledge of existing rules was used. Pearson's Chi-squared tests were performed to compare characteristics between groups. The study revealed, for accident prevention purposes, a concerning lack of general knowledge of existing rules. Risk-inducing situations that could result in severe injuries were largely assessed incorrectly. The appropriate intuitive behavior increases with age and experience: youths and beginners are less able to implement the FIS rules than older and more experienced snowboarders. Stakeholders, such as parents, ski resorts, clubs or schools, should direct educational efforts at high-risk groups. Further research is needed to determine the causal relation between snowboard-related injuries and disregard of FIS rules.

The Multidisciplinary Process Leading to Return From Underperformance and Sustainable Success in the World's Best Cross-Country Skier.

PURPOSE: To investigate the factors associated with underperformance and the subsequent changes in training characteristics and supportive actions when returning to the world's best cross-country skier. METHODS: The participant is the most decorated winter Olympian, with 8 Olympic gold medals, 18 World Championship titles, and 114 World Cup victories. Training data were categorized by training form (endurance, strength, and speed); intensity (low, moderate, and high); and mode (running, cycling, and skiing/roller skiing). In addition, test data were retrospectively analyzed, and interviews were performed with the participant and her support team. RESULTS: After the competitive season, the participant had 8 weeks without systematic training and an evaluation process aiming to detect the factors contributing to underperformance. Here physiological, technical, and psychological challenges were detected. As a consequence, the participant included less high-intensity training (1.2 vs 2.1 sessions/wk, P = .011); more moderate-intensity training (0.9 vs 0.4 sessions/wk, P = .016); and more low-intensity training (6.9 vs 5.9 sessions/wk, P = .036) during the general preparation phase but with similar total endurance training load as previous season. In addition, more strength training (1.6 vs 1.1 h/wk, P = .036) and new ski-specific strength exercises were included. Finally, the athlete's autonomy when planning and adjusting training was increased, nontraining stressors were reduced, more frequent testing was included, systematic mental training was initiated, her nutritional strategy was adjusted, and her asthma treatment was optimized. CONCLUSIONS: Overall, the current case study could be used as a framework for the holistic approach to treating an overtraining condition and for generation of new hypothesis in this exiting area.

An Exploration of Sensation Seeking in Persons With Disabilities in Rehabilitation.

PURPOSE: This study reports the findings of a study about sensation-seeking or high-risk/challenging sports in persons who have disabilities. DESIGN: Exploratory, cross-sectional, and descriptive. METHODS: Two hundred and twenty-three recruitment e-mails were sent to potential participants. Data were collected through Qualtrics. FINDINGS: Mean score for Contextual Sensation Seeking Questionnaire for Skiing and Snowboarding (M = 30.21, SD = 8.18) was significantly lower than a sample of able-bodied skiers and snowboarders, t(239) = 2.75, p = .006. Mean for impulsive sensation seeking was lower than the same sample of able-bodied athletes cited in a previous study, t(240) = 4.56, p = .001. Means for the Zuckerman Kuhlman Personality Questionnaire subscales were impulsivity (M = 1.98, SD = 4.05) and sensation seeking (M = 6.75, SD = 2.68). CONCLUSIONS: This group scored lower in sensation seeking compared to able-bodied high-risk/challenging sports activities participants. Sensation seeking is not a motivating factor in this sample. CLINICAL RELEVANCE: Nurses could encourage rehabilitation patients to engage in challenging activities for personal and group mastery.

Freeriding-Only a need for thrill?: Comparing different motives and behavioural aspects between slope skiers and freeride skiers.

OBJECTIVES: To compare professional freeride skiers (an experienced high-risk cohort) with recreational freeride skiers (a less experienced high risk cohort) and slope skiers (a low-risk sport cohort) in regard to their motives and their reported accident involvement. DESIGN: Case-control study. METHODS: In an online survey, skiers completed the German Sensation Seeking, Emotion Regulation and Agency Scale and the German Accident and Close Calls in Sport Inventory. Freeriders were further asked about their risk-management strategies and their use of safety equipment. For every professional freerider (total 31; 29% female) within the sample, two matched controls (age, gender) were allocated (slope skier and recreational freerider). Univariate analyses of variance (ANOVAs) and Chi-square differences were calculated. RESULTS: Freeriders showed significantly higher sensation seeking scores than slope skiers. No differences were found in the experience of agency while participating; however freeriders experienced higher agency transfers after the activity than slope skiers. No further motivational disparities between recreational or professional freeriders were shown. Both freeride samples reported a significantly higher accident and close call involvement than slope skiers. Accident and close call involvement was not predicted by motives of participation. CONCLUSIONS: Freeriding might provide beneficial transfer effects as shown through a higher agency transfer, for participants into aspects of everyday life. Nevertheless it should not be ignored that the potential behavioural gain of freeriding is at the cost of a higher risk which is underlined by the higher involvement in accidents and experienced close calls of freeriders compared to slope skiers.

The Impact of Priming on Speed Reduction on a Ski Slope.

We tested a field-adapted priming procedure (a technique used to subtly activate mental representations and guide behavior) on a ski slope, with the goal of reducing risk behavior in winter sports. At cableway stations, skiers were initially exposed eight times to a prevention poster displaying a logo and a "slow down" message. The "slow down" concept was activated on the ski slope by exposing skiers (or not) 10 times to the logo featured on the poster. We used a radar device to measure the skiers' speed data just before a slope intersection. We hypothesized that the mean speed would be lower in the presence of the logo than in its absence. As predicted, the speed was lower (by 0.9 km/h) when the skiers had been primed (i.e., exposed to the logo). This decrease was relevant, since any reduction in speed downhill will reduce kinetic (impact) energy and thus the risk of injury in a collision. The effect of priming was statistically significant at noon and in the afternoon but not in the morning. Our pilot study is the first to show that a priming procedure can influence the speed of skiers at a dangerous location. Our findings open up new perspectives for the prevention of risk behavior in winter sports.

The Minne-Loppet Motivation Study: An Intervention to Increase Motivation for Outdoor Winter Physical Activity in Ethnically and Racially Diverse Elementary Schools.

PURPOSE: To test the effectiveness of an intervention to increase motivation for physical activity in racially diverse third- through fifth-grade students. DESIGN: Natural experiment. SETTING: Elementary schools in Minneapolis, Minnesota. PARTICIPANTS: Two hundred ninety-one students in 18 Minne-Loppet Ski Program classes and 210 students in 12 control classrooms from the same schools. INTERVENTION: The Minne-Loppet Ski Program, an 8-week curriculum in elementary schools that teaches healthy physical activity behaviors through cross-country skiing. MEASURES: Pretest and posttest surveys measured self-determination theory outcomes: intrinsic exercise motivation, intrinsic ski motivation, autonomy, competence, and relatedness. ANALYSIS: Hierarchical linear regression models tested treatment effects controlled for grade, race, sex, and baseline measures of the outcomes. RESULTS: Minne-Loppet program students showed significantly greater motivation to ski (ß = 0.95, 95% confidence interval [CI]: 0.15-1.75) and significantly greater perceived competence (ß = 0.78, 95% CI: 0.06-1.50) than students in control classrooms. Treatment effects for general exercise motivation and perceived competence differed by race. African American students in Minne-Loppet classes showed significantly greater general exercise motivation (ß = 1.08, 95% CI: 0.03-2.14) and perceived competence (ß = 1.95, 95% CI: 0.91-2.99) than African American students in control classes. CONCLUSION: The Minne-Loppet program promoted perceived competence and motivation to ski. Future improvements to the Minne-Loppet and similar interventions should aim to build general motivation and provide support needed to better engage all participants.

Relations Between Self-Reported and Linguistic Monitoring Assessments of Affective Experience in an Extreme Environment.

INTRODUCTION: Approaches for monitoring psychosocial health in challenging environments are needed to maintain the performance and safety of personnel. The purpose of the present research was to examine the relationship between 2 candidate methods (self-reported and linguistics) for monitoring affective experience during extreme environment activities. METHODS: A single-subject repeated-measures design was used in the present work. The participant was a 46-year-old individual scheduled to complete a self-supported ski expedition across Arctic Greenland. The expedition lasted 28 days, and conditions included severe cold, low stimulation, whiteouts, limited habitability, and threats to life and limb. During the expedition, the participant completed a daily self-report log including assessment of psychological health (perceptions of control and affect) and a video diary (emotion). Video diary entries were subjected to linguistic inquiry and word count analyses before the links between self-report and linguistic data across the expedition period were tested. RESULTS: Similarities in the pattern of self-reported and linguistic assessments emerged across the expedition period. A number of predictable correlations were identified between self-reported and linguistic assessments of affective/emotional experience. Overall, there was better agreement between self-reports and linguistic analytics for indicators of negative affect/emotion. CONCLUSIONS: Future research should build on this initial study to further test the links between self-reported affect and emotional states monitored via linguistics. This could help develop methods for monitoring psychological health in extreme environments and support organizational decision making.

Effect of Cold on Proprioception and Cognitive Function in Elite Alpine Skiers.

PURPOSE: To determine the effect of cold ambient conditions on proprioception and cognitive function in elite alpine skiers. METHODS: 22 high-level alpine skiers and 14 control participants performed a proprioceptive-acuity (active movement-extent discrimination) and a cognitive (planning task) test in cold (8°C) and temperate (24°C) ambient conditions. RESULTS: All participants displayed an increase in thermal discomfort and the amount of negative affects in the cold environment (all P < .05). Average proprioceptive acuity was significantly better in the elite skiers (0.46° ± 0.12°) than in the control group (0.55° ± 0.12°) (P < .05) and was not affected by cold ambient conditions, except for a shift in the pattern of error (over- vs underestimation, P < .05). Cognitive performance was similar between elite skiers and control participants in temperate environments but decreased in the cold in the control group only (P < .05) becoming lower than in elite skiers (P < .05). CONCLUSION: Elite alpine skiers showed a significantly better proprioceptive acuity than a control population and were able to maintain their performance during a cognitive task in a cold environment.

Grade and speed have greater influence on HR and RPE than ability, sex, and age in alpine skiing.

The purpose of this study was to investigate the influence of ski slope grade, skiing speed, skiing ability, sex, and age on HR, RPE, and energy expenditure responses during recreational alpine skiing. Thirty-eight participants were divided by age, sex, and skiing ability. Instructor- and self-paced skiing conditions were conducted on 10° and 19.8° slopes. Skiing HR was recorded, RPE collected at the end of each run, and energy expenditure calculated. The pertinent results of this study demonstrate that the interactions of grade × speed, speed × age, and grade × age and the main effects of speed and grade significantly influenced %HRmax, mean HR, RPE, and energy expenditure during skiing. When %HRmax is taken into account, the older skiers skied at a greater relative intensity than the young skiers. The sex, age, and skiing ability main effects did not have a significant influence on mean HR, RPE, and energy expenditure. These data demonstrates that increased speed and grade results in increased physiological stress. Using mean, HR data may not be the best option for assessing physiological stress during exercise in the older athlete as it does not account for the influence of the ageing process.

Effect of ski geometry on aggressive ski behaviour and visual aesthetics: equipment designed to reduce risk of severe traumatic knee injuries in alpine giant slalom ski racing.

BACKGROUND/AIM: Aggressive ski-snow interaction is characterised by direct force transmission and difficulty of getting the ski off its edge once the ski is carving. This behaviour has been suggested to be a main contributor to severe knee injuries in giant slalom (GS). The aim of the current study was to provide a foundation for new equipment specifications in GS by considering two perspectives: Reducing the ski's aggressiveness for injury prevention and maintaining the external attractiveness of a ski racer's technique for spectators. METHODS: Three GS ski prototypes were defined based on theoretical considerations and were compared to a reference ski (Pref). Compared to Pref, all prototypes were constructed with reduced profile width and increased ski length. The construction radius (sidecut radius) of Pref was ≥ 27 m and was increased for the prototypes: 30 m (P30), 35 m (P35), and 40 m (P40). Seven World Cup level athletes performed GS runs on each of the three prototypes and Pref. Kinetic variables related to the ski-snow interaction were assessed to quantify the ski's aggressiveness. Additionally, 13 athletes evaluated their subjective perception of aggressiveness. 15 sports students rated several videotaped runs to assess external attractiveness. RESULTS: Kinetic variables quantifying the ski's aggressiveness showed decreased values for P35 and P40 compared to Pref and P30. Greater sidecut radius reduced subjectively perceived aggressiveness. External attractiveness was reduced for P40 only. CONCLUSIONS: This investigation revealed the following evaluation of the prototypes concerning injury prevention and external attractiveness: P30: no preventative gain, no loss in attractiveness; P35: substantial preventative gain, no significant loss in attractiveness; P40: highest preventative gain, significant loss in attractiveness.
