Fields neighboring the disciplines of kinesiology and sports science have called for more interdisciplinary work, including the adoption of critical approaches to research. This scoping review explored the degree to which critically-aligned research has developed within these disciplines. The goal was to identify who this research studied, what methods were used, and which theoretical and conceptual frameworks were adopted. Publications between 2010-2022 in six top kinesiology and sports science journals using four databases were searched using keywords to identify critically-aligned research. A multi-step screening process was used to identify and sort articles that adequately fit the criteria of critically-aligned research. The scoping review identified 5666 entries of which 3300 were unique publications. 76 articles were assessed to be critically-aligned. Four themes regarding demographics emerged: Geographic area, gender, race/ethnicity/indigeneity, and inequality/inequity. Regarding methodology, three major theoretical and conceptual frameworks emerged: ecological, socio-economic, and cultural. Overall, a relatively small number of studies fit our search criteria, suggesting that critically-aligned research remains at the margins of the disciplines. For the studies that were critically-aligned, they often centered the Global North and were inconsistent in their application of categories such as race, ethnicity, inequality and equity. These studies were diverse in their methodological approach while relying on ecological, socio-economic, and cultural frameworks. To heed the calls for a more interdisciplinary approach, and to advance the disciplines more generally, kinesiology and sports science should expand their adoption of critical approaches to research.

PURPOSE: To compare the responses in knee joint muscle activation patterns to different perturbations during gait in healthy subjects.SCOPE: Nine healthy participants were subjected to perturbed walking on a split-belt treadmill. Four perturbation types were applied, each at five intensities. The activations of seven muscles surrounding the knee were measured using surface EMG. The responses in muscle activation were expressed by calculating mean, peak, co-contraction (CCI) and perturbation responses (PR) values. PR captures the responses relative to unperturbed gait. Statistical parametric mapping analysis was used to compare the muscle activation patterns between conditions.RESULTS: Perturbations evoked only small responses in muscle activation, though higher perturbation intensities yielded a higher mean activation in five muscles, as well as higher PR. Different types of perturbation led to different responses in the rectus femoris, medial gastrocnemius and lateral gastrocnemius. The participants had lower CCI just before perturbation compared to the same phase of unperturbed gait.CONCLUSIONS: Healthy participants respond to different perturbations during gait with small adaptations in their knee joint muscle activation patterns. This study provides insights in how the muscles are activated to stabilize the knee when challenged. Furthermore it could guide future studies in determining aberrant muscle activation in patients with knee disorders.

Do young adolescents enjoy long distance cycling to school? An exploratory research to understand attitudes and behavior in the NetherlandsIntroduction The change from primary to secondary school has a negative impact on physical activity levels of adolescents. Cycling is an easy way of integrating physical activity into adolescents’ daily life. In the Netherland, cycling is rather common and around 80% of adolescents are cycling to school every day although they have to travel around 9km; however, the percentage dropped dramatically for adults. To maintain the habits of cycling is important to understand the attitude towards cycling and other mode of travel. This study aimed to uncover factors that makes young adolescents cycling to school unpleasant for them , using qualitative method.MethodsAn online interactive map-based questionnaire (Maptionnaire), focus group discussions, carrying a GPS logger and an online travel diary for 5 days, were used to understand attitudes and behavior towards long distance cycling to school in 36 adolescents (12-15 years). ResultsAlthough the majority of participants were cycling to school, only 30% of them chose cycling as their favorite travel mode. More than 80% of participants stated that the car is a more convenient travel mode, because protects you in bad weather and is faster than bicycle. Also, 70% of participants thought cycling in rural areas and along busy roads in city is not safe. A lot of adolescents stated that crowded cycling pathways around the school especially in the morning, makes cycling stressful. Almost half of adolescents doubted whether cycling to school is good for their health. They stated that it is stressful to cycle in overcrowded cycling pathways around the school in the morning. Long distance cycling on windy/rainy days, lack of traffic safety, and crowded cycling pathways around the school in the morning were mentioned as main reasons to make adolescents’ cycling to school unpleasant for them.ConclusionCycling intervention should focus on improving adolescents’ traffic safety perceptions, and to take urgent steps to improve over-crowded cycle lanes at rush hours. Also it is important to educate adolescents on health benefits of cycling. It will help to maintain adolescents’ habit of cycling after reaching the age at which it is possible to ride a moped/car.
