Self-regulation (SR) in pre-schoolers is a strong predictor of different aspects of mental health and wellbeing. However, SR only recently has been examined concerning physical activity and its effects on cognitive performance. In the present study, 49 preschool children aged 4–5 years were submitted to classroom movement breaks (CMBs) of 15-min with different degrees of difficulty. Before beginning the intervention, SR (i.e., head, toes, knees and shoulders test, HTKS) and skill levels were assessed for tasks demand adjustment to individual resources and the counterbalanced assignment of the participants to the groups. Similarly, after the intervention, the performance on the HTKS was re-evaluated. There was a general intervention effect on the SR of pre-schoolers, regardless of the difficulty level of the task [F (3) = 11.683, p-value < 0.001, η²p = 0.438]. Nevertheless, it seems that only when CMBs stimulate the children cognitively with optimal difficulty, is it possible to obtain benefits. We recommend providing teachers with professional support when implementing physical activity breaks in their daily program to generate an individualized level of cognitive load that would allow children to reach the optimal challenge point.

Background: The objective of this study was to analyze the impacts of a comprehensive physical exercise program with cognitive involvement during the school day on the executive functions and interpersonal skills of 5- and 6-year-old children. Methods: A total of 68 children participated in a 3-week pre–post intervention. Results: The results showed significant improvements in executive functions and interpersonal skills under the experimental conditions compared to the control group. These positive effects were observed to persist after a three-week follow-up. Conclusions: Therefore, the ActivaMotricidad program, which focuses on developing fundamental motor skills through cognitive, cooperative, and coordinative challenges, can serve as a useful and low-cost tool to achieve the objectives of comprehensive development and sustainability for children in early childhood education.

Background: Attentional resource allocation during sports practice is associated with the players’ perceived mental load. However, few ecological studies address this problem by considering the players’ characteristics (e.g., practice experience, skill and cognition). Therefore, this study aimed to analyse the dose-response effect of two different types of practice, each with different learning objectives, on mental load and motor performance by using a linear mixed model analysis. Method: Forty-four university students (age 20.36 ± 3.13 years) participated in this study. Two sessions were conducted, one based on a standard rules 1 × 1 basketball situation (“practice to maintain”) and one with motor, temporal and spatial restrictions in 1 × 1 tasks (“practice to learn”). Results: “Practice to learn” produced a higher perceived mental load (NASA-TLX scale) and a worse performance than “practice to maintain”, but was moderated by experience and inhibition (p = 0.001). The same happens in the most demanding restriction (i.e., temporal, p < 0.0001). Conclusion: The results showed that increasing the difficulty of 1 × 1 situations through restrictions harmed the player’s performance and increased their perceived mental load. These effects were moderated by previous basketball experience and the player’s inhibition capacity, so the difficulty adjustment should be based on the athletes themselves.

Background/Objectives: Anterior cruciate ligament (ACL) injury is common in interaction sports and has severe physical and psychological consequences. Recent research suggests that neurocognitive factors, such as proactive inhibitory control, may influence injury risk. The present work compares the proactive inhibitory performance ability of athletes with no ACL injury and ACL-rehabilitated athletes (ACLR). Methods: This study involved 60 athletes from interaction sports (30 with no history of ACL injury and 30 ACL rehabilitated athletes). During the experimental session, participants performed an executive go–no-go task to assess proactive inhibitory control. Results: The ACLR group exhibited higher adjusted-precision response times (p = 0.011), higher inhibitory failures response times (p < 0.001), poorer accuracy (p = 0.003), and higher commission error rate (p = 0.026) than the group of athletes with no history of ACL injury. Conclusions: Athletes rehabilitated from an ACL injury show inferior performance in proactive inhibitory control, evidenced by lower accuracy and higher reaction times than athletes without a history of injury. Consequently, physiotherapists and exercise professionals should consider cognition during ACL injury rehabilitation and physical retraining before returning to sporting activity.

Endurance physical exercise is accompanied by subjective perceptions of exertion (reported perceived exertion, RPE), emotional valence, and arousal. These constructs have been hypothesized to serve as the basis for the exerciser to make decisions regarding when to stop, how to regulate pace, and whether or not to exercise again. In dual physical-cognitive tasks, the mental (executive) workload generated by the cognitive task has been shown to influence these perceptions, in ways that could also influence exercise-related decisions. In the present work, we intend to replicate and extend previous findings that manipulating the amount of executive load imposed by a mental task, performed concomitantly with a submaximal cycling session, influenced emotional states but not perceived exertion. Participants (experienced triathletes) were asked to perform a submaximal cycling task in two conditions with different executive demands (a two-back version of the n-back task vs. oddball) but equated in external physical load. Results showed that the higher executive load condition elicited more arousal and less positive valence than the lower load condition. However, both conditions did not differ in RPE. This experimental dissociation suggests that perceived exertion and its emotional correlates are not interchangeable, which opens the possibility that they could play different roles in exercise-related decision-making.

Background: Cognitive load is an important factor influencing anterior cruciate ligament (ACL) injuries. However, few studies have systematically manipulated and quantified cognitive load to examine its biomechanical and neurophysiological consequences. Purpose: This study aimed to investigate the impact of varying cognitive load levels on biomechanical variables associated with ACL injury risk. The study further explored whether individual cognitive performance was related to alterations in ACL injury risk indicators and examined prefrontal cortical activity as an objective marker of mental workload. Study Design: Controlled laboratory study. Methods: A total of 30 athletes engaged in team sports performed a single-leg drop vertical jump (SL-DVJ) under 5 cognitive conditions of varying complexity using a modified Go/No-Go task. Biomechanics, behavioral, and prefrontal hemodynamic data variables were recorded. Cognitive performance was assessed through a computerized Go/No-Go task. Results: Higher cognitive load significantly increased peak ground-reaction forces and altered joint kinematics, specifically reducing knee flexion and increasing knee abduction during landing, especially in conditions that required high cognitive demand ( P < .001). These changes were accompanied by increased prefrontal hemoglobin (OxyHb) concentrations, suggesting elevated cortical activation. Furthermore, lower cognitive performance, notably lower accuracy and higher precision-adjusted response time, was associated with more pronounced biomechanical patterns (such as greater ground-reaction forces) and an increase in the risk of ACL injury ( r = −0.471, P < .01; r = 0.650, P < .001, respectively). Conclusion: An increased cognitive load altered the biomechanics of movement during an SL-DVJ, leading to a potential for increased risk of ACL injury. Moreover, athletes with poorer cognitive control may have been more susceptible to these effects. Prefrontal cortex (PFC) activity increased under conditions of higher cognitive demand. The pattern of regional activation varied according to the type of stimulus (eg, higher OxyHb concentrations for the ventrolateral PFC were observed during the change goal-stimulus condition), suggesting a specific functional organization of the PFC according to the particular demands of executive control. Clinical Relevance: These findings highlight the importance of integrating cognitive challenges into injury prevention and rehabilitation strategies. The findings emphasize the need to consider cognitive load as a central variable in injury risk mitigation and to evaluate cognitive performance as a potential prognostic indicator.
