Background: People with intellectual disability participate in organised sports to a lesser extent than people in general. The aim of this study was to explore the motivation for engaging in sports among athletes using the theoretical framework of sense of belonging.

Method: Semi-structured online interviews were carried out with athletes (N = 15, 8/7 women/men, 29.5 ± 9 years) with intellectual disabilities.

Results: The main theme 'Empower me to grow as an athlete-adapt the support to help me develop my sport skills and social aspects' showed that motivation, competence, perception, and opportunities were important factors for engaging in sports. Support was an important factor for creating adapted opportunities.

Conclusion: Athletes with intellectual disabilities have motivation, want to feel competent, and to be athletes who belong in sports and develop as such. They also appreciate coaches giving adapted support that enhances understanding and promotes inclusion in the sport community.

PURPOSE: This study aimed to investigate how pole length, incline, and skiing intensity affect lower back muscle activation in elite cross-country skiers. This addressing a critical gap in understanding the biomechanical demands and risk of low back pain of double poling (DP).

METHOD: Eleven elite cross-country skiers performed skiing trials on a treadmill, varying in incline (flat vs. 6°), intensity (two self-selected speeds, training speed and racing speed), and pole lengths. Muscle activity was measured by surface electromyography on the erector spinae thoracic and lumbar muscles, on the left and right side. A motion capture system was used for kinematic analysis of the lower back-pole moment arm and the hip angle during the DP cycle.

RESULTS: Compared to men, female skiers had a significantly higher (p < 0.001), overall muscle activation for the m. erector spinae lumbar on both the left and right side (26% of MVC vs. 15% of MVC, and 28% of MVC vs. 22% of MVC, for the left and right side, respectively). No correlations were found, neither between muscle activation to the lower back-pole moment arm, or to the hip angle.

CONCLUSION: The findings suggest that female skiers experience significantly higher lumbar erector spinae activation during DP, potentially indicating greater susceptibility to back-related issues. The results also highlight the need to tailor training and right adapted equipment to mitigate lower back stress, especially in flat terrain high-intensity conditions. The asymmetrical muscle activity and gender differences underscores the need for further investigation into biomechanical factors influencing back muscle engagement in cross-country skiing.

AIM: Evidence on physical activity (PA), sedentary time, and fitness in adolescents with impairments has been limited. We aimed to compare outcomes in Swedish adolescents with and without impairments and between impairment types.

METHODS: This cross-sectional study, from September to December 2019, comprised of adolescents from 34 mainstream schools within 3 h' drive of Stockholm, Sweden. Parents reported impairment status. PA and sedentary time were measured with accelerometers during school and leisure time on weekdays and weekends. Fitness was estimated using the Ekblom-Bak submaximal cycle test, sports participation was self-reported and multilevel mixed models were used for analyses.

RESULTS: We enrolled 972 adolescents (51% girls), with a mean age of 13.4 ± 0.3 years. Just under a third (31%) had impairments. Adolescents with impairments showed lower PA levels, less adherence to recommendations, lower fitness and less participation in organised sports than those without impairments. Those with learning or visual impairments engaged in less vigorous activity and the former had lower fitness levels.

CONCLUSION: Adolescents with impairments were less physically active, more sedentary and had lower fitness than peers without impairments. This emphasises the need for equitable opportunities for PA, to support long-term health and well-being in adolescents with impairments.

Background

People with intellectual disabilities are less physically active and suffer from ill-health more than the general population. Support staff play an important role in the person's life. This study aimed to explore the support staff's experiences regarding the feasibility of adapted web-based exercise for people with intellectual disabilities.

Method

Participants with intellectual disabilities living in community-based settings were recruited for a web-based exercise study. Eight semi-structured interviews were carried out with their support staff before and after the intervention period.

Results

The main theme, ‘Support staff are crucial for feasibility’ encompasses the importance of communication, structure, and motivation in improving physical activity for people with intellectual disabilities.

Conclusion

The experiences of support staff, indicate that a web-based exercise program is feasible for the target group, and one way to overcome challenges for PA, where the role of the staff is crucial.

Individuals with intellectual disability (ID) are less physically active than individuals without ID, and rarely reach the recommended daily level of physical activity (PA). It is understood that both social interaction and the ability to perform physical work affect participation in daily activity as well as PA. Individuals with ID generally have a higher risk of hypertension and obesity-related cardiovascular diseases than individuals without ID. Professional service providers, teachers and parents are often those being asked about potential challenges related to PA, as it is more seldom that this knowledge comes from the target group (ID) themselves. This identifies a lack of knowledge about PA and sports for individuals with ID. The aim of this study was to identify perceptions of, and motivation for, PA and sports among adolescents with ID. Twelve Swedish male and female adolescents with ID participated in the study, which comprised one semi-structured interview. The interviews identified three main categories: Activity, Surroundings and Body- and health awareness. Adolescents with ID seemed intrinsic motivated to participate in PA, organised sports and activities in general. Support from significant others, teachers, family and friends and support as well as the feeling of joy are connected to normative beliefs which all seem crucial. The participants were aware of their limitations, but sometimes feel bullied and afraid of being excluded, which relates to their normative beliefs. Participation in PA and organised sports may be positively associated with health, but limitations such as lack of awareness and support from society challenge the perception of ‘fitting in’. This research has raised the voice of adolescents with ID and identified the need for increased knowledge of their perceptions for a more inclusive world. School PE is an arena where adolescents can still be reached regarding PA and thereby should be prioritised. 

Adults with intellectual disability (ID) have higher degree of sedentary lifestyle and participate in physical activity less compared to the general population. The aim of this cross-sectional study was to analyse if participation in Special Olympics increase the level of physical activity (PA) and influence physical health aspects such as BMI, muscular strength and aerobic fitness for people with ID. Data were analysed from the Special Olympics Sweden Invitational Games 2020, on athletes (n=38) and non-athletes with ID (n=20), of strength (partial sit-up-, seated push-up-, handgrip- and timed sit to stand test), aerobic fitness (2 min step up test), BMI and a PA-questionnaire. Athletes showed higher levels of PA moderate intensity, both groups had high BMI, low levels of aerobic fitness and strength. This study indicate that Special Olympics athletes and non-athletes with ID need to increase their physical activity of both strength training and PA higher intensity to improve physical health aspects.

Purpose: This study aimed to investigate how rifle carriage and skiing speed during biathlon roller skiing affect range of motion (ROM) in joint angles and equipment (skis and poles), the vertical distance between shoulders and treadmill (vertdist), as well as possible sex differences associated with rifle carriage. Methods: Fourteen biathletes (6 women, 8 men) roller-skied on a treadmill at submaximal and simulated race speeds, with (WR) and without (NR) a rifle, using gears 3 and 2. Kinematical data for the whole body, poles, roller-skis, rifle, and treadmill were monitored using a 3D motion capture system. Movements determined as flexion/extension (x), abduction/adduction (y), and/or internal/external rotation (z) were analyzed for the hip, shoulder, thorax, knee, ankle, elbow, poles, and roller skis. ROM (the difference between maximal and minimal angles) in joints and equipment, and vertdist were analyzed over six skiing cycles during each condition (WR and NR) and speed. Results: The maximal vertdist was lower for WR compared with NR (gear 3: 1.53 ± 0.06 vs 1.54 ± 0.06 m; gear 2: 1.49 ± 0.06 vs 1.51 ± 0.06 m; both p &lt; 0.001). ROM in the upper body was altered when roller skiing WR (movements decreased in thorax and shoulder (x) and increased in elbow (only gear 3) (x), thorax (only gear 2), and shoulder (y) and (z); all p &lt; 0.05) and increased with speed, without differences between sexes (p &gt; 0.05). Conclusion: Since rifle carriage and speed appear to affect the kinematics of roller skiing, coaches, and biathletes are advised to perform skiing technique training under competition-like conditions (i.e., at race speeds while carrying the rifle). 

This study investigated micro-pacing strategies during sit para-biathlon. Six elite sit para-biathletes wore a positioning system device during the world-championships in three different competition formats (Sprint, Middle-distance, and Long-distance). Total Skiing Time (TST), penalty-time, shooting-time, and Total Race Time (TRT) were analysed. One-way analyses of variance were used to compare the relative contributions of TST, penalty-time, and shooting-time to TRT across the three race formats. Statistical parametric mapping (SPM) was used to determine the course positions (clusters) where instantaneous skiing speed was significantly associated with TST. The contribution of TST to TRT was lower for the Long-distance (80 & PLUSMN; 6%) compared to the Sprint (86 & PLUSMN; 5%) and Middle-distance (86 & PLUSMN; 3%) races, however this difference was not statistically significant (p > 0.05). The proportional contribution of penalty-time to TRT was significantly greater (p < 0.05) for the Long-distance (13 & PLUSMN; 6%) compared to the Sprint (5 & PLUSMN; 4%) and Middle-distance (4 & PLUSMN; 3%) races. Statistical parametric mapping (SPM) revealed specific clusters where instantaneous skiing speed was significantly associated with TST. For example, over all laps during the Long-distance race, the fastest athlete gained 6.5 s over the slowest athlete in the section with the steepest uphill. Overall, these findings can provide insights into pacing strategies and help para-biathlon coaches and athletes optimise training programmes to improve performance.
