It is well-known that multitasking impairs the performance of one or both of the concomitant ongoing tasks. Previous studies have mainly focused on how a secondary task can compromise visual or auditory information processing. However, despite dual tasking being critical to motor performance, the effects of dual-task performance on proprioceptive information processing have not been studied yet. The purpose of the present study was, therefore, to investigate whether sensorimotor task performance would be affected by the dual task and if so, in which phase of the sensorimotor task performance would this negative effect occur. The kinematic variables of passive and active knee movements elicited by the leg drop test were analyzed. Thirteen young adults participated in the study. The dual task consisted of performing serial subtractions. The results showed that the dual task increased both the reaction time to counteract passive knee–joint movements in the leg drop test and the threshold to detect those movements. The dual task did not affect the speed and time during the active knee movement and the absolute angle error between the final and the target knee angles. Furthermore, the results showed that the time to complete the sensorimotor task was prolonged in dual tasking. Our findings suggest that dual tasking reduces motor performance due to slowing down proprioceptive information processing without affecting movement execution.

Children and adolescents with disabilities (CAWD) represent 11% of Israeli children and adolescents. The 10 core indicators of the Global Matrix on Para Report Cards of physical activity (PA) of CAWD were used to create the 2022 Israeli Para Report Card. A panel of four experts reviewed resources and synthesized evidence of PA behaviors and policies for CAWD in Israel, converted the data to grades, and charted subcategories of language, sex, and disability across population. Data sources were surveys, reports, and memberships in sport federations and clubs. Among CAWD, levels of participation in daily PA were poor (<20%; Grade F), and participation of CAWD in sports was even lower (<10%; Grade F). A lack of environmental infrastructure may explain the low levels of participation. Females, Arabic speakers, and physiological CAWD need particular attention. Establishing governmental policies and interventions is required to increase overall PA and participation in sports among CAWD.

The objectives of this work were (a) to adopt the Active Healthy Kids Global Alliance Report Card methodology to evaluate the state of physical activity (PA) for French children and adolescents with disabilities (CAWD) and (b) to identify the strengths, weaknesses, opportunities, and threats (SWOT) perceived by French PA experts for promoting PA among CAWD. The harmonized Active Healthy Kids Global Alliance Report Card development process was used to assign a grade to the 10 common PA indicators. SWOT templates were completed by PA experts and then collapsed in a summary figure. Despite increasing efforts to provide active opportunities to CAWD, concerning low grades were assigned to behavioral indicators. SWOT analysis provided important insights for the promotion of PA in CAWD. This work highlighted the need for the inclusion of CAWD in a comprehensive national PA surveillance system and for more efficient strategies promoting PA specifically targeting CAWD in France.

South Korea has developed its first Para Report Card on physical activity (PA) for children and adolescents with disabilities. Five national surveillance databases were used to evaluate PA indicators based on the benchmarks and grading rubric provided by Active Healthy Kids Global Alliance. Report card evaluation committees were invited to grade and assess the results using strengths, weaknesses, opportunities, and threats analysis. Five indicators (overall PA, D+; organized sports and PA, D−; active transportation, D−; physical fitness, D+; and government, A+) and one additional indicator (sleep, C−) were assigned a letter grade. The other five indicators were graded as incomplete. The Para Report Card revealed a significant gap between the behavioral-indicator grades (D− to D+) and the policy-indicator grade (A+), suggesting that government strategies and investment have not yet been translated into behavioral PA among children and adolescents with disabilities.

We present two studies examining the relationship between athlete leadership quality and team resilience and explored the mediating effect of team identification. In Study 1, 194 soccer players (M age = 18.50, SD = 4.49) from eight national teams participated. Structural equation modeling showed cross-sectionally that the four types of athlete leadership qualities were positively related to the characteristics of resilience and negatively to vulnerability under pressure. Team identification was shown to be a mediator of these relationships. Study 2, with four different time-points, involved 208 young soccer players (M age = 16.05, SD = 3.39) from two professional clubs (i.e., La Liga). Cross-lagged panel models revealed that task leadership quality (Times 1–2) was positively related to the characteristics of resilience (Times 3–4) and negatively to vulnerability under pressure (Times 3–4). However, team identification did not mediate these relationships. Therefore, practitioners should consider the perceptions of leader quality to achieve benefits during competition.
