Introduction: To determine if athletes with coordination impairment (CI) can continue playing wheelchair rugby (WR), while an evidence-based classification system, including impairment tests for CI is not yet available. This is a defensible practise if they show similar activity limitations as athletes with other eligible impairment types (OI) within the same sports class. Methods: Standardised activities were measured in 58 elite WR athletes; 14 with CI and 44 with OI. Wheelchair activities consisted of 20-meter sprint, 12-meter sprint with full stop, intermittent sprint (3-meter sprint, stop, 3-meter sprint, stop, 6-meter sprint with full stop), sprint-curve-slalom-curve, turn on the spot 180°, turn on the spot 90°, stop, turn 90°in the same direction, X-test (short circuit with sharp turns) without the ball. Ball activities consisted of maximal throwing distance, precision throwing short (25% of maximum throw) and long (75% of maximal throw) distance and X-test with the ball (pick-up the ball and dribble whilst pushing). Descriptive statistics were used and Spearman’s Rank correlation was assessed for athletes with CI and OI for each outcome measure. Differences between athletes with CI and OI were assessed using a Mann-Whitney U test. Results: Most activities showed a high correlation with the athlete class in both athletes with CI and athletes with OI. Furthermore, outcome measures of athletes with CI overlapped with athletes with OI in the same sports class for all activities. There was a trend for worse performance in athletes with CI in turn on the spot 90°, stop, turn 90°in the same direction, the short distance one handed precision throw (P 0.11)and in the X-test with the ball (P 0.10). Discussion: Despite the current lack of evidence based impairment tests for CI, it is a defensible practise to not exclude athletes with CI from WR with the current classification system. The trends for differences in performance that were found can support athletes and coaches in optimising performance of athletes with CI.

Endurance athletes seek for the optimal balance in training stress and recovery so they can perform at their best and avoid injuries. The PhD thesis of Ruby Otter at the School of Sport Studies (Hanze University of Applied Sciences) and the Center of Human Movement Sciences (UMCG, University of Groningen) showed that not only physical stress and recovery, but also psychosocial stress and recovery influence performance and injury risk of endurance athletes. During the research project, 115 endurance athletes have been monitored for two years. The athletes kept a daily training log including information about any injuries. Every 1 to 3 weeks the athletes filled out a psychosocial stress and recovery questionnaire and they came into the SportsFieldLab Groningen to perform exercise tests every 6 weeks. Results showed that an increase in stress and a decrease in recovery are associated to decreased performance parameters. An unplanned negative life event disturbed perceived psychosocial stress and recovery over a relatively short period and it impaired performance parameters of runners. In addition, the risk of sustaining an injury increased after increased relative training loads (physical stress). Finally, a new submaximal rowing test has shown to be reliable and practical for predicting maximal performance of rowers. The findings in this thesis support the notion that psychosocial as well as physical stress and recovery play a role in performance changes of endurance athletes. Athletes and coaches could benefit from monitoring physical and psychosocial factors so that training programs can be adapted for each individual.

Rationale/Purpose: High-performance sport systems offer athletes access to a range of experts including excellent coaches. This study examines the macro-, meso- and micro-level factors associated with coaching elite women athletes within a high-performance sport system. Design/methodology/approach: This research was underpinned by constructionism and critical feminism. The data were collected via semi-structured in-depth interviews with 10 international male elite rowing coaches with experience in coaching men and women athletes and analysed using thematic analysis. Findings: The data shows that at the micro-level, coaches differentiate their practices based on the gender of the athlete. These practices are influenced by meso-level factors (perceived value of sport participated by women) and shaped by macro-level factors (socio-cultural background of the coaches). Practical implications: Coaches’ socio-cultural experiences influence their construct of gender and affect their approach to coaching women athletes. Hence identifying macro-level factors can help managers understand coaches’ perspectives, philosophy and practice at a micro-level. https://doi.org/10.1080/23750472.2019.1641139 LinkedIn: https://www.linkedin.com/in/donna-de-haan/

Wheelchair users with a spinal cord injury (SCI) or amputation generally lead an inactive lifestyle, associated with reduced fitness and health. Digital interventions and sport and lifestyle applications (E-platforms) may be helpful in achieving a healthy lifestyle. Despite the potential positive effects of E-platforms in the general population, no studies are known investigating the effects for wheelchair users and existing E-platforms can not be used to the same extent and in the same manner by this population due to differences in physiology, body composition, exercise forms and responses, and risk injury. It is, therefore, our aim to adapt an existing E-platform (Virtuagym) within this project by using existing data collections and new data to be collected within the project. To reach this aim we intend to make several relevant databases from our network available for analysis, combine and reanalyze these existing databases to adapt the existing E-platform enabling wheelchair users to use it, evaluate and improve the use of the adapted E-platform, evaluate changes in healthy active lifestyle parameters, fitness, health and quality of life in users of the E-platform (both wheelchair users and general population) and identify determinants of these changes, identify factors affecting transitions from an inactive lifestyle, through an intermediate level, to an athlete level, comparing wheelchair users with the general population, and comparing Dutch with Brazilian individuals. The analysis of large datasets of exercise and fitness data from various types of individuals with and without disabilities, collected over the last years both in the Netherlands and Brazil, is an innovative and potentially fruitful approach. It is expected that the comparison of e.g. wheelchair users in Amsterdam vs. Sao Paulo or recreative athletes vs. elite athletes provides new insight in the factors determining a healthy and active lifestyle.

Along with the rapidly growing number of disabled people participating in competitive sports, there is an increased need for (para)medical support in disability sports. Disabled athletes experience differences in body composition, metabolism, training load and habitual activity patterns compared with non-disabled athletes. Moreover, it has been suggested that the well-recognized athlete triad, and low energy availability and low bone mineral density in particular, is even a greater challenge in disabled athletes. Therefore, it is not surprising that sport nutritionists of disabled athletes have expressed an urgency for increased knowledge and insights on the nutritional demands of this group. This project aims to investigate energy expenditure, dietary intake, body composition and bone health of disabled athletes, ultimately leading to nutritional guidelines that promote health and optimal sports performance for this unique population. For this purpose, we will conduct a series of studies and implementation activities that are inter-related and build on the latest insights from sports practice, technology and science. Our international consortium is highly qualified to achieve this goal. It consists of knowledge institutes including world-leading experts in sport and nutrition research, complemented with practical insights from nutritionists working with disabled athletes and the involvement of athletes and teams through the Dutch and Norwegian Olympic committees. The international collaboration, which is a clear strength of this project, is not only focused on research, but also on the optimization of professional practice and educational activities. In this regard, the outcomes of this project will be directly available for practical use by the (para)medical staff working with disabled athletes, and will be extensively communicated to sport teams to ensure that the new insights are directly embedded into daily practice. The project outcomes will also be incorporated in educational activities for dietetics and sport and exercise students, thereby increasing knowledge of future practitioners.
